Filter by:The main objective of this study is to determine the effectiveness of a nutritional intervention (olive leaf extract) combined with a specific training session (MICT or SIT) on PDH activation (as well as other protein expressions) and exercise-induced muscle fatigue.
This is a monocentric study comparing hamstring and quadriceps neuromuscular fatigue after simulated soccer game, anaerobic and aerobic training sessions. The purpose of this study was: 1. To quantify the decrease of isometric force immediately after a simulate soccer game. 2. To characterize peripheral and central fatigue between hamstring and quadriceps muscles and described the kinetics of recovery after specific tasks of soccer training. 3. To compare the level neuromuscular fatigue induced by anaerobic and aerobic training. 4. To highlight correlation between neuromuscular fatigue and performance markers.
Potential factors involved in neuromuscular fatigue were classified into two categories: 1) central factors involving the central nervous system and neural pathways, and 2) peripheral factors occurring within the muscle beyond the neuromuscular junction. In adults, it has been shown that peripheral factors contribute to a large part of the fatigue induced by repeated maximal contractions. However in children, central factors could account for the development of fatigue to a greater extent. Force-generating capacity and musculotendinous stiffness could be two of the discriminatory factors accounting for the differences in the neuromuscular fatigue between children and adults. Force production capacity and musculotendinous stiffness vary as function of muscle length. Naturally, they could differ depending on the muscle groups studied. The main aim of the present protocol is to compare the effect of knee extensors and ankle plantarflexors length on the development and aetiology of neuromuscular fatigue, in children and adults. The investigators formulated the hypotheses that at short muscle length force and low musculotendinous stiffness, differences in force between children and adults would be reduced. Thus neuromuscular fatigue development and aetiology would be similar between both groups. The results of the present protocol will allow to better understanding of the aetiology of neuromuscular fatigue in children and help improving training or rehabilitation programs.
