Introduction: Skeletal muscle is a flexible and ever changing tissue and the role of costameric proteins in its response to different stimuli is not well defined. The aim of this study was to investigate the effect of progressive resistance exercise on β1 integrin and vinculin proteins in fast and slow twitch skeletal muscles of male rats. Methods: Twelve male Wistar rats (weight: 298±5.2 gr...

Background. BDNF and NT-4/5 have been proposed to be involved in the coordinated adaptations of the neuromuscular system to the elevated level of activity, but an activity-dependent expression of neurotrophins in skeletal muscle is not well established. Objectives. We, therefore, investigated the effect of one session of resistance exercise on mRNA expression of some neurotrophins in Slow and ...

We investigated the acute and long-term effects of low-intensity resistance exercise (knee extension) with slow movement and tonic force generation on muscular size and strength. This type of exercise was expected to enhance the intramuscular hypoxic environment that might be a factor for muscular hypertrophy. Twenty-four healthy young men without experience of regular exercise training were as...

muscle-derived neurotrophins are thought to contribute to the adaptation of skeletal muscle to exercise. the nt-4/5 protein is one of the family members of neurotrophins that remains rather unknown compared to other members. the aim of this present study was to determine the effect of one session of resistance exercise on the levels of nt-4/5 protein in soleus and flexor hallucislongus muscles ...

The purpose of this study was to examine the influence of exercise order on strength and muscle volume (MV) after 12 weeks of nonlinear periodized resistance training. The participants were randomly assigned into 3 groups. One group began performing large muscle group exercises and progressed to small muscle group exercises (LG-SM), whereas another group started with small muscle group exercise...

Strength and Conditioning Journal 13 in their training regimes (18, 25). It appears that explosive exercises tend to enhance an athlete’s ability to generate high rates of force development (18, 22, 25, 54), whereas slow exercises tend to impair this ability (24, 25, 50). Almost any exercise can be performed explosively depending upon the resistance used. Several studies and review articles hav...
