The purpose of this study was to determine the effect of eccentric exercise on correlated motor unit discharge (motor unit synchronization and coherence) during low-force contractions of the human biceps brachii muscle. Eight subjects (age, 25 +/- 7 yr) performed three tasks involving isometric contraction of elbow flexors while EMG (surface and intramuscular) records were obtained from biceps ...

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...

methylsulfonylmethane (msm) is a sulfur-containing compound commonly found in diet and known to reduce oxidative stress. this trial was conducted to determine whether single dose supplementation with msm attenuates post-exercise oxidative stress in healthy untrained young men. sixteen untrained men volunteered for this study. participants were randomized in a double-blind placebo-controlled fas...

The aim of this study was to investigate alterations in haemoglobin conformation and parameters related to oxidative stress in whole erythrocytes, membranes, and plasma after a single bout of exercise in a group of young untrained men. Venous blood samples from eleven healthy young untrained males (age = 22 ± 2 years, BMI = 23 ± 2.5 kg/m(2)) were taken from the antecubital vein before an increm...

The study investigates the effects of eccentric exercise of the quadriceps on proprioception of the knee in weight and non-weight bearing tasks. Proprioception of the exercised leg was assessed at 120° and 150° of knee extension in 15 healthy adults (age 25.0 ± 3.6 yrs) before, immediately after, and 24h following eccentric exercise of the quadriceps. Three tests of proprioception were performe...
