PURPOSE Muslim athletes may continue training and competing while they are fasting. There is a concern about negative effects of fasting on sports performance. This study aimed to investigate the influence of two training time frames on athletes' body composition and performance during Ramadan fasting. METHODS An observational study was conducted and thirty four male volunteer athletes from d...

BACKGROUND Falls are one of the most common medical complications post-stroke. Physical exercise, particularly exercise that challenges balance, reduces the risk of falls among healthy and frail older adults. However, exercise has not proven effective for preventing falls post-stroke. Falls ultimately occur when an individual fails to recover from a loss of balance. Thus, training to specifical...

introduction: to cope with novel changes, organizations must think beyond environmental compatibility and seek to take advantage of potential opportunities. a paradigm for this is the enhancement of organizational flexibility, speed, quality, and agility. human resources are the most important tool for enhancement of organizational agility and the most valuable asset of each organization and co...

The purpose of this study was to determine the ability of the elderly central nervous system to modulate spinal reflex output to functionally decrease a spinally induced balance perturbation. In this case, the soleus H reflex was used as the source of perturbation. Therefore, decreasing (down training) of the soleus H reflex was necessary to counteract this perturbation and to better maintain p...

the purpose of the present study was to compare the effects of one- and two-session(s)-per-week training programs on musculoskeletal and cardiovascular indices in sedentary female university students. 111 voluntary sedentary female university students were randomly divided into three groups (one session groups (os): n=37, mean age 21.02±1.73 years, two sessions group (tn): n=35, mean age 21.17±...

In this paper a new form of the homptopy perturbation method is used for solving oscillator differential equation, which yields the Maclaurin series of the exact solution. Nonlinear vibration problems and differential equation oscillations have crucial importance in all areas of science and engineering. These equations equip a significant mathematical model for dynamical systems. The accuracy o...

insulin – like growth factor – i (igf-1) plays a role in the skeletal muscle in the development, growth, repair, and maintenance of the tissues in an autocrine / paracrine as well as endocrine fashion. the aim of the present study was to investigate the response of growth factors to two different training methods. 14 male volunteers were selected and divided randomly into two groups. group a (p...

BACKGROUND Little is known about the epidemiology of dog sport-related injuries. This study examines injuries among handlers and dogs in the sport of dog agility. METHODS A cross-sectional pilot study captured data on demographics, exposures, and injury for a sample of agility handlers and dogs. Logistic regressions predicted odds of injury. RESULTS Survey of 217 handlers and 431 dogs ident...
