BACKGROUND Mitochondrial dysfunction may represent a pathogenic factor in Huntington disease (HD). Physical exercise leads to enhanced mitochondrial function in healthy participants. However, data on effects of physical exercise on HD skeletal muscle remains scarce. We aimed at investigating adaptations of the skeletal muscle mitochondria to endurance training in HD patients. METHODS Thirteen...

Mental demands have been associated with increased risk of injuries; however, its influence on muscle fatigability remains unclear. The aim of this study was to investigate the interaction of mental workload and physical workload on muscle fatigability during repetitive shoulder work. Twelve young participants, balanced by gender, performed shoulder abduction exercises until exhaustions at thre...

BACKGROUND Single-set resistance training (SSRT) improves strength and function in older adults with COPD. However, its effect on quality of life (QOL) has not been evaluated. This study evaluated the effect of SSRT on QOL in COPD patients enrolled in pulmonary rehabilitation (PR) and identified relationships between muscular strength, endurance and QOL. METHODS Nineteen men and women (70.5 ±...

The relationship between physical activity and health-related physical fitness was evaluated in 282 Taiwanese adolescents 12-14 years of age. The subjects were randomly selected from the 7th, 8th and 9th grades in two junior high schools in Taiwan. Physical activity was estimated as total daily energy expenditure and energy expenditure in moderate-to-vigorous physical activity from 24-hour acti...

The purpose of this study was to assess the relationships between obesity and measures of back and core muscular endurance in firefighters. Methods. A cross-sectional study was conducted in career firefighters without low back pain. Obesity measures included body mass index (BMI) and body fat percentage assessed with air displacement plethysmography. Muscular endurance was assessed with the Mod...

Background. Irisin is the result of the proteolysis of fibronectin type III domain-containing protein 5, the levels of which are determined by physical activity. Objective(s). This study aims to identify changes in FNDC5 gene expression and the heart muscle irisin levels in male rats following 8 weeks resistance and endurance training. Methods. Fifteen male rats (10-12 weeks old and 331.8&plu...

Speed, heart rate, lactate and uric acid alterations led to reduced performance and hamper the health status of endurance horses. The aim of this study was to investigate on the effects of speed, heart rate, lactate and uric acid on the performance of Arabian horses during a 120 km endurance race. One hundred and eighty four Arabian endurance horses were physically examined and blood samples we...
