The present study examined associations between the ciliary neurotrophic factor (CNTF) 1357 G --> A polymorphism and the muscle strength response to a unilateral, upper arm resistance-training (RT) program among healthy, young adults. Subjects were 754 Caucasian men (40%) and women (60%) who were genotyped and performed a training program of the nondominant (trained) arm with the dominant (untr...
PURPOSE The purpose of the current study was to characterize the role of aerobic exercise in the gene expression of the angiotensin-converting enzyme (ACE) and the β2-adrenergic receptor (ADRB2) in untrained men. METHODS Twenty untrained middle-aged men were randomly assigned to exercise (Exe) and control (Con) groups. The Exe group performed aerobic exercises for eight weeks. ACE mRNA and AD...
A treadmill walking test was developed in order to provide a suitable method of assessing the fitness levels of sedentary middle-aged men (mean age, 44.3 yrs) at submaximal intensity. The incremental stages of the test enabled subjects to terminate the workload whenever undue discomfort was experienced. The test procedure was used in a preliminary experiment to compare the cardiovascular and me...
The purpose of this study was to determine whether acute hypoxia alters the deoxygenation level in vastus lateralis muscle during a 30 s Wingate test, and to compare the muscle deoxygenation level between sprint athletes and untrained men. Nine male track sprinters (athletic group, VO2max 62.5 ± 4.1 ml/kg/min) and 9 healthy untrained men (untrained group, VO2max 49.9 ± 5.2 ml·kg(-1)·min(-1)) pe...
conclusions the present study has demonstrated that a combination of exercise and silymarin can improve body composition and adiponectin levels. background silymarin has powerful antioxidant properties, but its effects on athletic performance are poorly understood. objectives the present study was undertaken to evaluate the effects of 4 weeks of endurance or strength exercise, with or without s...
