This investigation evaluated whether moderate-intensity cycle ergometer training affects satellite cell and molecular responses to acute maximal concentric/eccentric resistance exercise in middle-aged women. Baseline and 72 h postresistance exercise vastus lateralis biopsies were obtained from seven healthy middle-aged women (56 ± 5 years, BMI 26 ± 1, VO2max 27 ± 4) before and after 12 weeks of...

A design algorithm is derived, for a calculating minimum allowable electrical clearances in alternating and direct current “permissible” equipments, which are authorized to operate in gassy mines and tunnels under Part 18 of Title 30, Code of Federal Regulations [1]. The calculated clearances apply to operations at altitudes ranging up to 12 000 ft (3658 m) above sea level. The minimum allowabl...

The aim of this study was primarily to determine the reliability and factor validity of four muscular endurance tests, and secondly, to identify gender differences in muscular endurance tests. For this purpose, a new muscular endurance test was constructed for pupils aged between seven and eight (CROCO). The research was done on a sample of 71 pupils aged between seven and eight (35 girls and 3...

background: given widespread deleterious health effects of an augmented inflammatory state, identification of therapies that reduce inflammation is critical. the purpose of the present study was to investigate the effects of 10 weeks endurance training on pro-inflammatory cytokines and their relationships with cortisol and testosterone hormones in sedentary young men. methods: twenty sedentary ...

Endurance exercise has been shown to improve metabolic outcomes in obesity and type 2 diabetes; however, the physiological and molecular mechanisms for these benefits are not completely understood. Although endurance exercise has been shown to decrease lipogenesis, promote fatty acid oxidation (FAO), and increase mitochondrial biosynthesis in adipose tissue, muscle, and liver, its effects on in...

Endurance, marathon-type exertion is known to induce adverse changes in the immune system. Increased airway hyper-responsiveness and airway inflammation are well documented in endurance athletes and endurance exercise is considered a major risk factor for asthma in elite athletes. Yet, the mechanisms underlying this phenomenon are still to be deduced. We studied the effect of strenuous enduranc...

research has shown that chronic, long and exhausting endurance training programs cause iron deficiency. this problem can have a negative effect on physical performance. the aim of this research was to study the effect of endurance training and iron supplement on anemic indexes [hemoglobin (hb), hematocrit (hct), red blood cell (rbc), total iron binding capacity (tcbc) and ferritin], and cytochr...
