the aim of this study was to determine the short-term (1 session) and long-term (36 sessions) effects of various exercise training (endurance, sprint, and combined) on plasmatic indexes of muscle damages (lactate dehydrogenase, creatine kinase, and malondialdehyde). for this purpose, 40 young rats (3 months old) were randomly divided into four groups including control, endurance, sprint, and co...

background: the aim of this study was to investigate muscle damage indicators and electromyography activities of quadriceps muscles at 25° of hip flexion in untrained healthy females after an eccentric exercise induced muscle fiber damage.   methods : a total of 14 healthy females participated in this pre-experimental study. the subjects performed maximal eccentric quadriceps contractions at 25...

fasting induces short-term physiological adaptations which spare the body's remaining carbohydrate stores and mobilize lipid stores to provide a substitute fuel for many tissues and organs, especially skeletal muscle. rodent studies show that regular occurrence of fasting then refeeding, stimulates adaptations in muscle which make the animal better placed to withstand a further period of fastin...

Purpose: An appropriate activity of the knee agonist -antagonist muscles is important to resist against abnormal abduction-adduction moments loads around knee joint and reduce the risk of knee injuries. Exercise training has been commonly used as an intervention to improve neuromuscular activity within the synergic and/or agonist-antagonist muscles. However, maximizing the effectiveness of exer...

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 ...

abstract background: chronic obstructive pulmonary disease (copd) is currently the fourth cause of mortality worldwide. patients with copd experience periods of dyspnea, fatigue, and disability, which impact on their life. the objective of this study was to investigate the effect of short‑term inspiratory muscle training on exercise capacity, exertional dyspnea, and pulmonary lung function. mat...

satellite cells (scs) are the most abundant skeletal muscle stem cells. they are widely recognized for their contributions to maintenance of muscle mass, regeneration and hypertrophy during the human life span. these cells are good candidates for cell therapy due to their self-renewal capabilities and presence in an undifferentiated form. presently, a significant gap exists between our knowledg...
