Physical exercise has proven to be an extremely useful tool in health enhancement, health maintenance, and rehabilitation in addition to its role in conditioning for competitive sports. Exercise is defined as activity that involves the generation of force by the activated muscles. While various sport activities and events involve a wide range of metabolic power production, exercise for fitness and health occupies two discrete areas of the power scale: relatively low intensity that promotes… Expand
Basic Principles Regarding Strength, Flexibility, and Stability Exercises
Static flexibility programs have been shown to improve joint range of motion and tolerance to stretch but do not appear to reduce the risk of musculoskeletal injury and may impair muscle performance immediately after a static stretch. Expand
Evidence-based risk assessment and recommendations for exercise testing and physical activity clearance in apparently healthy individuals.
Given this risk-benefit relationship, the PAR-Q is an appropriate method to identify those at higher risk across a wide age span and should be used in conjunction with appropriate clinical guidelines for guiding individuals towards graduated PA. Expand
Age-and-exercise-related effects on cardiac power output
Overall cardiac function was greater in the active men, compared with age-matched, sedentary controls, and body composition had a significant impact on the interpretation of CPO data, indicating that healthy ageing is associated with reductions in overall cardiac function. Expand
Task Failure during Exercise to Exhaustion in Normoxia and Hypoxia Is Due to Reduced Muscle Activation Caused by Central Mechanisms While Muscle Metaboreflex Does Not Limit Performance
Close to task failure, muscle activation is lower in hypoxia than in normoxia, indicating that metaboreflex activation has a minor impact on sprint performance and dissociation between the recovery of EMGRMS and performance. Expand
Exercise preferences among men with prostate cancer receiving androgen-deprivation therapy.
Investigation of acceptability of and preferences for physical activity participation in men receiving androgen-deprivation therapy for prostate cancer and the small number of participants meeting ACSM and AHA guidelines suggest feasibility of and support the need for the development of exercise programs in this population.

An Adequate Interset Rest Period for Strength Recovery During a Common Isokinetic Test
It is suggested that a 1:3 work:rest ratio is sufficient during a common isokinetic strength test, as an effective method of standardizing rest periods in isokinetics testing. Expand

Whilst the assessment of quality of life (QoL) and well-being has burgeoned in the past 50 years, there still remains relatively little research into its treatment in psychology, in spite of theExpand
Comparison the prevalence and severity of dysmenorrhea among athletes and non-athletes and its relation with body composition.
It seems that performing regular exercise can be used as a preventing, treating or supplementary method in control of the early dysmenorrhea. Expand
The Interplay Between Quality of Life and Resilience Factors in Later Life: A Network Analysis
Age-related challenges and transitions can have considerable social, psychological, and physical consequences that may lead to significant changes in quality of life (QoL). As such, maintaining highExpand
Complementary and Alternative Medicine Therapy Use of Western Turkish Students for Menstrual Symptoms
Background: This study was conducted to determine the methods of complementary and alternative (CAM) use for the treatment of perimenstrual symptoms. Methods: The sample of this descriptive andExpand
