Endurance exercise training results in profound adaptations of the cardiorespiratory and neuromuscular systems that enhance the delivery of oxygen from the atmosphere to the mitochondria and enable a tighter regulation of muscle metabolism. These adaptations effect an improvement in endurance performance that is manifest as a rightward shift in the 'velocity-time curve'. This shift enables athl...

the purpose of the present research was to examine the effect of one bout of exhaustive aerobic exercise with two different intensities on levels of serum mda in male smokers. for this purpose, 12 male smokers (age: 22.08 ±1.31 years, percent of body fat: 17.26 ±4.92% and body mass index: 23.21±2.96 kg/m2) were voluntarily selected and randomly participated in a crossover design in three situat...

The purpose of this study was to investigate the effects of creatine monohydrate supplementation on exercise performance and contractile variables in aerobic-anaerobic training rats. Twenty 90-day-old male Sprague Dawley rats were divided into two groups - creatine (Cr) and controls (K). The creatine group received creatine monohydrate as a nutritional supplement, whereas the control group was ...

BACKGROUND Several studies document reliable brain health benefits of acute exercise bouts. However, no prior studies have explored such effects among those living with co-morbid overweight/obesity and type 2 diabetes (T2DM), both of which are conditions associated with cognitive performance decrements. PURPOSE To examine the impact of a 30-min bout of moderate-intensity aerobic exercise on e...

Background Cordyceps militaris has been used in pre-workout supplement blends intended to improve aerobic performance. Mushroom blends containing Cordyceps may serve as an ergogenic aid by improving oxygen kinetics and delaying fatigue, but there is limited data on the effects of this ingredient during exercise. The purpose of this study was to determine the effects of 3 weeks of supplementatio...

OBJECTIVES To evaluate effects of stationary cycling to music versus interactive video game cycling on psychosocial functioning in obese adolescents. METHODS 30 obese adolescents aged 12-17 years were randomized to twice weekly laboratory-based sessions of stationary cycling to music or interactive video game cycling for a 10-week trial. Participant's self-reported measures of scholastic comp...

background: the purpose of this study was to investigate the effects of two types of rehabilitation techniques, including aerobic and strengthening exercises on patients with knee rheumatoid arthritis (ra). methods: 48 male patients with knee ra were randomly assigned into 3 groups, including aerobic exercises, strengthening exercise, and control. the two first groups completed their treatment ...
