Physical activity and exercise

مَا تَذَرُ مِن شَيۡءٍ أَتَتۡ عَلَيۡهِ إِلَّا جَعَلَتۡهُ كَٱلرَّمِيمِ

and it reduced everything it came up against to shreds

قَالَ قَآئِلࣱ مِّنۡهُمۡ لَا تَقۡتُلُواْ يُوسُفَ وَأَلۡقُوهُ فِي غَيَٰبَتِ ٱلۡجُبِّ يَلۡتَقِطۡهُ بَعۡضُ ٱلسَّيَّارَةِ إِن كُنتُمۡ فَٰعِلِينَ

[Another of them] said, ‘Do not kill Joseph, but, if you must, throw him into the hidden depths of a well where some caravan may pick him up.’

ٱذۡهَبُواْ بِقَمِيصِي هَٰذَا فَأَلۡقُوهُ عَلَىٰ وَجۡهِ أَبِي يَأۡتِ بَصِيرࣰ ا وَأۡتُونِي بِأَهۡلِكُمۡ أَجۡمَعِينَ

Take my shirt and lay it over my father’s face: he will recover his sight. Then bring your whole family back to me.’

وَمِنَ ٱلنَّاسِ مَن يَتَّخِذُ مِن دُونِ ٱللَّهِ أَندَادࣰ ا يُحِبُّونَهُمۡ كَحُبِّ ٱللَّهِۖ وَٱلَّذِينَ ءَامَنُوٓاْ أَشَدُّ حُبࣰّ ا لِّلَّهِۗ وَلَوۡ يَرَى ٱلَّذِينَ ظَلَمُوٓاْ إِذۡ يَرَوۡنَ ٱلۡعَذَابَ أَنَّ ٱلۡقُوَّةَ لِلَّهِ جَمِيعࣰ ا وَأَنَّ ٱللَّهَ شَدِيدُ ٱلۡعَذَابِ

Even so, there are some who choose to worship others besides God as rivals to Him, loving them with the love due to God, but the believers have greater love for God. If only the idolaters could see- as they will see when they face the torment- that all power belongs to God, and that God punishes severely

۞إِنَّ قَٰرُونَ كَانَ مِن قَوۡمِ مُوسَىٰ فَبَغَىٰ عَلَيۡهِمۡۖ وَءَاتَيۡنَٰهُ مِنَ ٱلۡكُنُوزِ مَآ إِنَّ مَفَاتِحَهُۥ لَتَنُوٓأُ بِٱلۡعُصۡبَةِ أُوْلِي ٱلۡقُوَّةِ إِذۡ قَالَ لَهُۥ قَوۡمُهُۥ لَا تَفۡرَحۡۖ إِنَّ ٱللَّهَ لَا يُحِبُّ ٱلۡفَرِحِينَ

Qarun was one of Moses’ people, but he oppressed them. We had given him such treasures that even their keys would have weighed down a whole company of strong men. His people said to him, ‘Do not gloat, for God does not like people who gloat

قَالُواْ ٱبۡنُواْ لَهُۥ بُنۡيَٰنࣰ ا فَأَلۡقُوهُ فِي ٱلۡجَحِيمِ

They said, ‘Build a pyre and throw him into the blazing fire.’

Go with this shirt of mine and cast it upon the face of my father so that he may come to seeing. Joseph said, " Take my shirt to Jacob, for his pain has not ceased from the time he saw the shirt stained with the wolf's blood. The balm will also be my shirt. " When they took the shirt from Egypt, the morning breeze was commanded to take the shirt's scent to Jacob's nostrils so that, before Joseph's messenger could give the good news, he would receive it from the Real's mes- senger and recognize the Real's perfect gentleness and favor toward him. According to the tasting of the recognizers, this is the divine breeze that wanders furtively around the world to the doors of the breasts of the faithful and the tawḤīd-voicers to see where there may be a limpid breast and an empty secret core in which to dwell. Her love came to me before I knew love- it came across a carefree heart and took poss

Among the people are some who take peers apart from God, loving them as if loving God. And those who have faith are more intense in love for God. If this were the only verse in the whole Qur'an about the faithful and God's friends, their eminence and honor would be complete, for the Lord of the Worlds is saying, “They love Me intensely and more completely than the unbelievers love their objects of worship.” Do you not see that every once in a while the unbelievers set up another idol and take up another object of worship. Like poor people, they are content with something carved of wood. Then, when they can, they take down the wooden one and make another from silver or gold. If their love for their object of wor- ship is real, why do they turn away from it toward another? They say that a man met a woman recognizer, and her beauty exercised its influence over his heart. He said, “'My all i

It did not leave anything any soul or property that it came upon without making it like decayed bones like something that is withered and in scattered pieces.

And in Musa, when We sent him to Fir'awn with a manifest authority (38)But (he) turned away along with his hosts, and said: "A sorcerer or a madman. (39)So We took him and his armies, and dumped them into the sea (Yamm), for he was blameworthy (40)And in 'Ad when We sent against them the barren wind (41)It spared nothing that it reached, but blew it into broken spreads of rotten ruins (42)And in Thamud, when they were told: "Enjoy yourselves for a while! (43)But they insolently defied the command of their Lord, so the Sa'iqah overtook them while they were looking (44)Then they were unable to rise up, nor could they help themselves (45)(So were) the people of Nuh before them. Verily, they were a people who were rebellious (46) Lessons from the Destruction of Fir'awn, 'Ad, Thamud, and the People of Nuh Allah the Exalted said, وَفِي مُوسَىٰ إِذْ أَرْسَلْنَاهُ إِلَىٰ فِرْعَوْنَ بِسُلْطَان

One of them namely Judah said ‘Do not kill Joseph but cast him throw him into the bottom of a well ghayābat al-jubb is the darkest recess of a well; a variant reading has the plural ghayābāt so that some caravan might pick him up if you are to do anything’ of what you desire in the way of separating Joseph from us so content yourselves with this solution.

Yet there be people who take to themselves compeers idols besides God that is other than God loving them by magnifying them and being subservient to them as God is loved that is as their love of Him; but those who believe love God more ardently than those who love their compeers because the former never reject God whereas the latter when faced with hardship soon abandon those compeers for God; If he if you O Muhammad (s) were to see those who did evil by taking to themselves compeers when idh here denotes idhā they see read either as active yarawna ‘they see’ or passive yurawna ‘they are made to see’ the chastisement you would see a grave sight that this is because the might the power and the vanquishing altogether a circumstantial qualifier belongs to God and that God is terrible in chastisement according to one reading the person listening to the verse governs the verb yarā ‘he sees’ a

Narrated Abu Tha'labah Al-Khushani:"I said: 'O Messenger of Allah! We are a people who hunt.' He said: 'If you send your dog and you mentioned the Name of Allah upon it, and he catches something for you, then eat it.' I said: 'Even if he kills it?' He said: 'Even if he kills it.' I said: 'We are a people who shoot (at game).' He said: 'What you catch with your bow, then eat it.'" He said: "Then I said:'Indeed we are a people who travel. We come across Jews, Christians, and Zoroastrians, and we do not find vessels other than theirs.' He said: 'If you do not find other than them, then wash them with water, then eat and drink from it

It was narrated that Salamah bin Nufail Al-Kindi said:"I was sitting with the Messenger of Allah when a man said: 'O Messenger of Allah! The people have lost interest in horses and put down their weapons, and they say there is no Jihad, and that war has ended.' The Messenger of Allah turned to face him and said: 'They are lying, now the fighting is to come. There will always be a group among my Ummah who will fight for the truth, for whom Allah will cause some people to deviate, and grant them provision from them, until the Hour begins and until the promise of Allah comes. Goodness is tied to the forelocks of horses until the Day of Resurrection. It has been revealed to me that I am going to die and will not stay long, and you will follow me group after group, striking one another's necks. And the place of safety for the believers is Ash-Sham

It was narrated that Abu Hurairah said:"The Messenger of Allah said: 'There is goodness tied to the forelocks of horses until the Day of Resurrection. And horses are of three types: Those that bring reward to man, those that are a means of protection for a man, and those that are a burden (of sin) for a man. As for those that bring reward, they are kept for the cause of Allah and for Jihad. No fodder enters their stomach but for everything that enters their stomachs, reward is written for him, even if he puts them out to pasture.'" And he quoted the Hadith

Narrated Al-Bara' bin 'Azib: That the Messenger of Allah (ﷺ) said: "Bring me a shoulder blade or tablet." Then he wrote: Not equal are those of believers who sit. 'Amr bin Umm Maktum who was behind him said: "Is there an exemption for me?" So the following was revealed: Except those who are disabled. There are narrations on this topic from Ibn 'Abbas, Jabir and Zaid bin Thabit. This Hadith is Hasan Sahih and it is a Hadith that is Gharib from the narration of Sulaiman At-Taimi from Abu Ishaq. And Shu'bah and Ath-Thawri reported this Hadith from Abu Ishaq

Narrated 'Abdullah bin 'Umar: A man came to Prophet (ﷺ) seeking permission to go for Jihad. So he said: 'Do you have parents (living)? ' He said: 'Yes.' He said: 'Then it is for them that you should perform Jihad.'" [Abu 'Eisa said:] There is something on this topic from Ibn 'Abbas. This Hadith is Hasan Sahih. (One of the narrators) Abul-Abbas is the blind (Al-A'ma) poet (Ash-Sha'ir), from Makkah, and his name is As-Sa'ab bin Farrukh

A five-staged comprehensive search of the literature was conducted in Medline, Web of Science and SciVerse Scopus using keywords

Reducing the decline in physical activity during pregnancy: a systematic review of behaviour change interventions.: Purpose: Physical activity (PA) typically declines throughout pregnancy. Low levels of PA are associated with excessive weight gain and subsequently increase risk of pre-eclampsia, gestational diabetes mellitus, hypertension disorders, delivery by caesarean section and stillbirth. Systematic reviews on PA during pregnancy have not explored the efficacy of behaviour change techniques or related theory in altering PA behaviour. This systematic review evaluated the content of PA interventions to re

Postural tachycardia syndrome: a heterogeneous and multifactorial disorder.

Postural tachycardia syndrome (POTS) is defined by a heart rate increment of 30 beats/min or more within 10 minutes of standing or head-up tilt in the absence of orthostatic hypotension; the standing heart rate is often 120 beats/min or higher. POTS manifests with symptoms of cerebral hypoperfusion and excessive sympathoexcitation. The pathophysiology of POTS is heterogeneous and includes impaired sympathetically mediated vasoconstriction, excessive sympathetic drive, volume dysregulation, and deconditioning. POTS is frequently included in the differential diagnosis of chronic unexplained symptoms, such as inappropriate sinus tachycardia, chronic fatigue, chronic dizziness, or unexplained spells in otherwise healthy young individuals. Many patients with POTS also report symptoms not attributable to orthostatic intolerance, including those of functional gastrointestinal or bladder disorde…

The reticular-activating hypofrontality (RAH) model of acute exercise.

We present here a comprehensive, neurocognitive model to account for the psychological consequences of acute exercise. There is a substantial amount of disparate research and the proposed mechanistic explanation meaningfully integrates this body of brain and behavioral data into a single, unified model. The model's central feature is a cascading, two-step process. First, exercise engages arousal mechanisms in the reticular-activating system. This activation process, which involves a number of neurotransmitter systems, has several interrelated effects on cognition and emotion but, in general, has evolved to facilitate implicit information processing. Second, exercise disengages the higher-order functions of the prefrontal cortex. This deactivation process, which is caused in part by resource limitations, also has several interrelated effects but, in general, has evolved to keep the ineffi…

An update: salivary hormones and physical exercise.

Saliva contains cells and compounds, of local and non-local oral origin, namely inorganic, organic non-protein, protein/polypeptide, and lipid molecules. Moreover, some hormones, commonly assayed in plasma, such as steroids, are detectable in oral fluid and peptide/protein, and non-steroid hormones have been investigated. The sports practice environment and athletes' availability, together with hormone molecule characteristics in saliva and physical exercise behavior effects, confirm this body fluid as an alternative to serum. This review focuses on the relation between salivary steroids and psycho-physiological stress and underlines how the measurement of salivary cortisol provides an approach of self-report psychological indicator and anxiety change in relation to exercise performance. The correlation between salivary and plasma steroid hormone (cortisol, testosterone, and dehydroepian…

Interventions that involve parents to improve children's weight-related nutrition intake and activity patterns - what nutrition and activity targets and behaviour change techniques are associated with intervention effectiveness?

Parent involvement is an important component of obesity prevention interventions. However, the best way to support parents remains unclear. This review identifies interventions targeting parents to improve children's weight status, dietary and/or activity patterns, examines whether intervention content and behaviour change techniques employed are associated with effectiveness. Seventeen studies, in English, 1998-2008, were included. Studies were evaluated by two reviewers for study quality, nutrition/activity content and behaviour change techniques using a validated quality assessment tool and behaviour change technique taxonomy. Study findings favoured intervention effectiveness in 11 of 17 studies. Interventions that were considered effective had similar features: better study quality, parents responsible for participation and implementation, greater parental involvement and inclusion …

Natural rewards, neuroplasticity, and non-drug addictions.

There is a high degree of overlap between brain regions involved in processing natural rewards and drugs of abuse. "Non-drug" or "behavioral" addictions have become increasingly documented in the clinic, and pathologies include compulsive activities such as shopping, eating, exercising, sexual behavior, and gambling. Like drug addiction, non-drug addictions manifest in symptoms including craving, impaired control over the behavior, tolerance, withdrawal, and high rates of relapse. These alterations in behavior suggest that plasticity may be occurring in brain regions associated with drug addiction. In this review, I summarize data demonstrating that exposure to non-drug rewards can alter neural plasticity in regions of the brain that are affected by drugs of abuse. Research suggests that there are several similarities between neuroplasticity induced by natural and drug rewards and that, …

Lifestyle and mental health.

Mental health professionals have significantly underestimated the importance of lifestyle factors (a) as contributors to and treatments for multiple psychopathologies, (b) for fostering individual and social well-being, and (c) for preserving and optimizing cognitive function. Consequently, therapeutic lifestyle changes (TLCs) are underutilized despite considerable evidence of their effectiveness in both clinical and normal populations. TLCs are sometimes as effective as either psychotherapy or pharmacotherapy and can offer significant therapeutic advantages. Important TLCs include exercise, nutrition and diet, time in nature, relationships, recreation, relaxation and stress management, religious or spiritual involvement, and service to others. This article reviews research on their effects and effectiveness; the principles, advantages, and challenges involved in implementing them; and t…

The relationship of autonomic imbalance, heart rate variability and cardiovascular disease risk factors.

Cardiovascular disease (CVD) is the leading cause of death and disability worldwide. The understanding of the risk factors for CVD may yield important insights into the prevention, etiology, course, and treatment of this major public health concern. Autonomic imbalance, characterized by a hyperactive sympathetic system and a hypoactive parasympathetic system, is associated with various pathological conditions. Over time, excessive energy demands on the system can lead to premature aging and diseases. Therefore, autonomic imbalance may be a final common pathway to increased morbidity and mortality from a host of conditions and diseases, including cardiovascular disease. Heart rate variability (HRV) may be used to assess autonomic imbalances, diseases and mortality. Parasympathetic activity and HRV have been associated with a wide range of conditions including CVD. Here we review the evide…

The pathophysiology of the aging skeleton.

In recent decades the population of both elderly men and women has grown substantially worldwide. Aging is associated with a number of pathologies involving various organs including the skeleton. Age-related bone loss and resultant osteoporosis put the elderly population at an increased risk for fractures and morbidity. Fortunately, in parallel our understanding of this malady has also grown substantially in recent years. A number of clinical as well as translational studies have been pivotal in providing us with an understanding of the pathophysiology of this condition. This article discusses the current concepts of age-related modulation of the skeleton involving intrinsic factors such as genetics, hormonal changes, levels of oxidative stress, and changes in telomere length, as well as extrinsic factors such as nutritional and lifestyle choices. It also briefly outlines recent studies …

Adult hippocampal neurogenesis, a once unorthodox concept, has changed into one of the most rapidly growing fields in neuroscience. The present report results from the ECNP targeted expert meeting in 2007 during which cellular plasticity changes were addressed in the adult brain, focusing on neurogenesis and apoptosis in hippocampus and frontal cortex. We discuss recent studies investigating factors that regulate neurogenesis with special emphasis on effects of stress, sleep disruption, exercise and inflammation, a group of seemingly unrelated factors that share at least two unifying properties, namely that they all regulate adult hippocampal neurogenesis and have all been implicated in the pathophysiology of mood disorders. We conclude that although neurogenesis has been implicated in cognitive function and is stimulated by antidepressant drugs, its functional impact and contribution to…

A faith-based and cultural approach to promoting self-efficacy and regular exercise in older African American women.

The health benefits of regular exercise are well documented, yet there has been limited success in the promotion of regular exercise in older African American women. Based on theoretical and evidence-based findings, the authors recommend a behavioral self-efficacy approach to guide exercise interventions in this high-risk population. Interventions should be developed that are age appropriate, group delivered in the community, focused on a single behavior, and only include general health education as a secondary purpose. Suggested cultural tailoring of exercise interventions includes addressing beliefs about exercise, focusing on the "possible self," promoting participants as "cultural consultants," and spiritual and religious strategies.

The effects of fasting on metabolism and performance.

An overnight fast of 8-10 h is normal for most people. Fasting is characterised by a coordinated set of metabolic changes designed to spare carbohydrate and increase reliance on fat as a substrate for energy supply. As well as sparing the limited endogenous carbohydrate, and increased rate of gluconeogenesis from amino acids, glycerol and ketone bodies help maintain the supply of carbohydrate. Many individuals undergo periodic fasts for health, religious or cultural reasons. Ramadan fasting, involving 1 month of abstention from food and fluid intake during daylight hours, is practised by a large part of the world population. This period involves a shift in the pattern of intake from daytime to the hours of darkness. There seems to be little effect on overall daily dietary intake and only small metabolic effects, but there may be implications for both physical and cognitive function. The …

The health benefits of yoga and exercise: a review of comparison studies.

Objectives: Exercise is considered an acceptable method for improving and maintaining physical and emotional health. A growing body of evidence supports the belief that yoga benefits physical and mental health via down-regulation of the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system (SNS). The purpose of this article is to provide a scholarly review of the literature regarding research studies comparing the effects of yoga and exercise on a variety of health outcomes and health conditions. Methods: Using PubMed((R)) and the key word "yoga," a comprehensive search of the research literature from core scientific and nursing journals yielded 81 studies that met inclusion criteria. These studies subsequently were classified as uncontrolled (n = 30), wait list controlled (n = 16), or comparison (n = 35). The most common comparison intervention (n = 10) involved e…

Factors that may impede the weight loss response to exercise-based interventions.

The results of exercise programmes designed to reduce body fat are disappointing. However, the reporting of weight loss as mean values disguises those individuals who do lose significant amounts of fat. Why some participants produce significant exercise-induced fat loss whereas others lose little or increase fat stores is likely to be an outcome of a range of behavioural (e.g. sleep deprivation, caloric intake), inherited (e.g. muscle fibre type, gender) and physiological (e.g. hyperinsulinaemia, hypothyroidism) factors. The following review highlights possible factors involved in weight loss and discusses how individual differences may determine the extent of weight loss after an exercise intervention. Finally, implications for the treatment and prevention of obesity are discussed.

Features and management of compulsive exercising in eating disorders.

Compulsive exercising is a common feature of patients with eating disorders. It is reported more frequently by patients with restricting-type anorexia nervosa than with other eating disorders. It is associated with higher eating disorder psychopathology, dietary restraint, general psychopathology, and specific personality features (ie, higher levels of perfectionism, persistence, and lower novelty seeking). It is a potent maintaining mechanism of eating disorder psychopathology, and it increases the risk of overuse injuries, bone fractures, and cardiac complications. It also appears to be a predictor of poor treatment outcome. Literature are lacking regarding its treatment, but cognitive-behavioral therapy in its enhanced form appears to be a promising treatment in hospitalized patients.

Chronobiology of sleep in humans.

Periodic circadian (24-h) cycles play an important role in daily hormonal and behavioural rhythms. Usually our sleep/wake cycle, temperature and melatonin rhythms are internally synchronized with a stable phase relationship. When there is a desynchrony between the sleep/wake cycle and circadian rhythm, sleep disorders such as advanced and delayed sleep phase syndrome can arise as well as transient chronobiologic disturbances, for example from jet lag and shift work. Appropriately timed bright light is effective in re-timing the circadian rhythm and sleep pattern to a more desired time, ameliorating these disturbances. Other less potent retiming effects may also be obtained from the judicious use of melatonin and exercise.

Brain neurotransmitters in fatigue and overtraining.

Since the publication of the serotonin hypothesis, numerous theories involving the accumulation or depletion of different substances in the brain have been proposed to explain central fatigue. Although the theoretical rationale for the "serotonin-fatigue hypothesis" is clear, several seemingly well-conducted studies have failed to support a significant role for 5-hydroxytryptamine in the development of fatigue. As brain function appears to be dependent upon the interaction of a number of systems, it is unlikely that a single neurotransmitter system is responsible for central fatigue. Several other mechanisms are involved, with evidence supporting a role for the brain catecholamines. Fatigue is therefore probably an integrated phenomenon, with complex interaction among central and peripheral factors. When prolonged and excessive training happens, concurrent with other stressors and insuff…

Exercise builds brain health: key roles of growth factor cascades and inflammation.

Human and other animal studies demonstrate that exercise targets many aspects of brain function and has broad effects on overall brain health. The benefits of exercise have been best defined for learning and memory, protection from neurodegeneration and alleviation of depression, particularly in elderly populations. Exercise increases synaptic plasticity by directly affecting synaptic structure and potentiating synaptic strength, and by strengthening the underlying systems that support plasticity including neurogenesis, metabolism and vascular function. Such exercise-induced structural and functional change has been documented in various brain regions but has been best-studied in the hippocampus - the focus of this review. A key mechanism mediating these broad benefits of exercise on the brain is induction of central and peripheral growth factors and growth factor cascades, which instruc…

Fibromyalgia--management of a misunderstood disorder.

Purpose: The purpose of this article is to review (a) what is currently known about the pathophysiology of fibromyalgia (FM), (b) how to identify patients who are susceptible to this disorder, and (c) the recommended pharmacological and nonpharmacological treatment options. Data sources: Data sources include reviews and original research from scholarly journals and Internet sites. Conclusions: There are approximately 6 million individuals in the United States diagnosed with FM, making it the third most prevalent rheumatologic disorder in this country. Failure to identify a specific causal mechanism for FM has resulted in a shift in the focus of research from etiology to treatment (Baumstark & Buckelew, 2002). Based on the literature, the most successful interventions for reduction of chronic symptoms in the FM patient is a combination of education, psychological assistance, and exercise,…

Diabetes and Ramadan: review of the literature.

During the month of Ramadan, Muslims fast every day from dawn to sunset. In the healthy subject, this fasting does not have any harmful consequences on health. However, it can induce several complications for patients with diabetes. The aim of this review twofold: first, it seeks to give some clues about methodological aspect of research during Ramadan and to show the impact of various diabetes monitoring and treatment, including biochemical and clinical parameters, diet and caloric intake, drug intake when fasting. Second, it intends to determine whether or not Ramadan fasting induces complications in patients with types 1 and 2 diabetes and ultimately to elaborate some advice as to the management of fasting patients. Several studies have shown that Ramadan fasting did not alter biochemical parameters in patients with type 2 diabetes. However, other studies have shown that there is eith…

Autonomic nervous system interaction with the cardiovascular system during exercise.

There is considerable recent evidence that parameters thought to reflect the complex interaction between the autonomic nervous system and the cardiovascular system during exercise testing can provide significant prognostic information. Specific variables of great importance include heart rate (HR) response to exercise (reserve), HR recovery after exercise, and multiple components of HR variability both at rest and with exercise. Poor HR response to exercise has been strongly associated with sudden cardiac death and HR recovery from a standard exercise test has been shown to be predictive of mortality. In addition, there are limited studies evaluating the components of HR variability at rest and during exercise and their prognostic significance. Research continues seeking to refine these exercise measurements and further define their prognostic value. Future findings should augment the po…

Gender-specific care of the patient with diabetes: review and recommendations.

Background: Men and women differ in their experience of diabetes mellitus (DM). For optimal prevention and treatment of the disease, these differences must be acknowledged. Unfortunately, most studies of diabetes have focused almost exclusively on men. Objective: The purpose of this review was to survey the literature about the sex-specific features of DM and to make recommendations for the gender-specific care of patients. Methods: An initial literature search was performed with Google Scholar and MEDLINE (1995-2005) using the search terms sex/gender, women, diabetes mellitus, and coronary artery disease, and specific topic headings such as polycystic ovary syndrome. The bibliographies of articles were used extensively to augment the search, and more specific search terms were included. The strength of each recommendation was assessed. Results: : Even when women were included in clinica…

Dance training is superior to repetitive physical exercise in inducing brain plasticity in the elderly.

Animal research indicates that a combination of physical activity and sensory enrichment has the largest and the only sustaining effect on adult neuroplasticity. Dancing has been suggested as a human homologue to this combined intervention as it poses demands on both physical and cognitive functions. For the present exploratory study, we designed an especially challenging dance program in which our elderly participants constantly had to learn novel and increasingly difficult choreographies. This six-month-long program was compared to conventional fitness training matched for intensity. An extensive pre/post-assessment was performed on the 38 participants (63-80 y), covering general cognition, attention, memory, postural and cardio-respiratory performance, neurotrophic factors and-most crucially-structural MRI using an exploratory analysis. For analysis of MRI data, a new method of voxel-…

Physical activity and quality of life.

Physical activity (PA) professionals and participants recognize enhanced quality of life (QoL) as a benefit of and motivator for PA. However, QoL measures are often problematic and rarely consider the participants'perspective. This paper focuses on recent findings from a larger project on the role of QoL in PA and health promotion. More specifically, we focus on the views of participants and potential participants to better understand the relationship of PA and QoL. In earlier stages of the project we began with a conceptual model of QoL and developed a survey. We now focus on participants' views and ask two questions: 1) what is QoL? and 2) how does PA relate to QoL? We first asked those questions of a large sample of university students and community participants as open-ended survey items, and then asked focus groups of community participants. Overall, participants' responses reflecte…

Physical activity in U.S. adults with diabetes and at risk for developing diabetes, 2003.

Objective: Given the risk of obesity and diabetes in the U.S., and clear benefit of exercise in disease prevention and management, this study aimed to determine the prevalence of physical activity among adults with and at risk for diabetes. Research design and methods: The Medical Expenditure Panel Survey is a nationally representative survey of the U.S. population. In the 2003 survey, 23,283 adults responded when asked about whether they were physically active (moderate or vigorous activity, > or =30 min, three times per week). Information on sociodemographic characteristics and health conditions were self-reported. Additional type 2 diabetes risk factors examined were age > or =45 years, non-Caucasian ethnicity, BMI > or =25 kg/m(2), hypertension, and cardiovascular disease. Results: A total of 39% of adults with diabetes were physically active versus 58% of adults without diabetes. Th…

Inverse association between physical inactivity and mental health in men and women.

Purpose: The Aerobics Center Longitudinal Study (ACLS) provides the opportunity to evaluate associations between measures of physical activity and mental health in a large and well-characterized population of men and women. Methods: Participants were 5451 men and 1277 women (20-88 yr) who completed a maximal fitness treadmill test and self-report measures of habitual physical activity, depressive symptoms (Center for Epidemiological Studies Scale for Depression; CES-D) and emotional well-being (General Well-Being Schedule; GWB). To evaluate the dose-response gradient of the association, we classified the sample, separately for men and women, into three levels of relative cardiorespiratory (CR) fitness (low, moderate, high) on the maximal treadmill test, and four levels on a physical activity index of weekly walking, jogging, and running. Results: In both men and women, there was a signif…
