objective(s): previous studies showed that skeletal muscle microcirculation was reduced in chronic heart failure. the aim of this study was to investigate the effects of endurance training on capillary and arteriolar density of fast and slow twitch muscles in rats with chronic heart failure. materials and methods: four weeks after surgeries (left anterior descending (lad) artery occlusion), chr...

The effect of resistance exercise on blood lipids is not clear yet. The purpose of this study was to examine the cholesterol responses to a heavy resistance leg press exercise emphasizing on the eccentric movement 24 and 48 hours following exercise and to quantify the cardiorespiratory responses of the exercise bout in an attempt to clarify the exercise characteristics that may be responsible f...

The purpose of this study was to examine the effects of isokinetic resistance exercise on torque development and movement time of individuals with cerebral palsy. Subjects (N = 30) 10 to 20 years of age were matched and assigned to one of three treatment groups: IR, isokinetic resistance; NR, repetitive practice with no resistance; and C, control. The treatment protocol consisted of exercising ...

the aim of the present study was to investigate the response of plasma visfatin to resistance exercise intensity and its relationship with insulin resistance, growth hormone and il-6. after familiarization and determining their maximum strength (1-rm), 15 healthy young subjects (age: 26.2±4.1 yr, weight: 75.1±9.1 kg) performed three resistance exercise sessions at intensities of 30%, 55% and 80...

Background: Theophylline may reverse steroid resistance and decrease inflammation in patients with chronic pulmonary disease and sulfur mustard (SM) induced bronchiolitis. This study was designed to assess the effects of low-dose theophylline on improvement of pulmonary function tests (PFTs) of SM exposed patients.Methods: In this comparative observational study, a group of SM-exposed victims d...

the purpose of this study was to evaluate the effect of short time circuit-resistance exercise with difference intensities on ghi/igf-i growth axis in healthy male students. for this purpose, 27 male students with mean and standard deviation of age 21.40±1.78 yr, height 172±0.45 cm, weight 68.85±5.39 kg were selected and randomly divided into three resistance exercise groups (each group, 9 subj...

BACKGROUND Among central and peripheral factors contributing to exercise intolerance (EI) in heart failure (HF), the extent to which skeletal muscle (SM) energy metabolic abnormalities occur and contribute to EI and increased fatigability in HF patients with reduced or preserved ejection fraction (HFrEF and HFpEF, respectively) are not known. An energetic plantar flexion exercise fatigability t...

introduction: strength training has an important role in the exercise programs of normal individuals and athletes and it also has numerous benefits on the health of human body and spirit. one of the types of these exercise is eccentric resistance exercise which is associated with negative physiological changes. thus: this study examined the effects of a single bout of eccentric resistance exerc...
