Fifteen elite amateur players volunteered participate. conducted during competitive matches the official season. Plasma concentrations were measured before after matches. Peak values for creatine kinase activity observed 24 h match. There no significant change between time points blood lactate concentration but secretion rate per unit surface significantly reduced Sweat ammonia increased...

This study was aimed at investigating the effects of a 21‐week period progressive strength or endurance training on peripheral blood mononuclear cells (PBMC) antioxidant enzyme gene expression and activity in healthy middle‐aged untrained men. Strength ( n =11) =12) were performed twice week, including resistance exercises to activate all main muscle groups cycle‐ergometer pedaling, respectively. mRNA levels catalase, glutathione peroxidase (GPx), mitochondrial superoxide dismutase (MnSOD)...

Changes in nuclear factor kappaB (NF-kappaB) activation induced peripheral blood mononuclear cells (PBMC) by acute eccentric exercise and submaximal training were investigated.Eleven subjects carried out two bouts of separated 6 wk training.Soreness, vertical jump height, plasma creatine kinase significantly modified after the first bout. NF-kappaB activation, p50 p65, phospho-IkappaBalpha phospho-IKK protein level, Mn-SOD expression increased PBMC, whereas IkappaBalpha level was reduced....

This study aimed to examine the relationship existing between maximum strength values in 2 common resistance training row exercises (bilateral bench pull [BBP] and one-arm cable [OACR]) short sprint performance elite kayakers. Ten junior kayakers (5 women 5 men) were tested on different days for 1 repetition (1RM) maximal voluntary isometric contraction both exercises. Moreover, a 12-m kayak was performed dew pond record split times (2, 5, 10 m), peak velocity, distance completed considering...

Purpose: The mechanical properties of resistance-training machines are a variable that may help to optimize sports performance and injury prevention protocols. purpose this study was examine two non-gravity-dependent training modalities on muscle structure function.
