TL;DR: In conclusion, maximal voluntary contraction force and SR Ca2+ uptake were impaired and muscle soreness was elevated after a high-level soccer game, with faster recovery of SR function in comparison with MVC force, soreness and muscle glycogen.

TL;DR: The present data suggest a role of the Na+-K+ pump in the control of K+ homeostasis and in the development of fatigue during repeated high-intensity exercise.

TL;DR: The present data suggest that short-term intensified training, even for trained soccer players, can increase muscle Na(+)-K(+) pump alpha(2)-isoform expression, and that cessation of training for 2 wk does not affect the expression of Na( +)-K (+) pump isoforms.

TL;DR: The present data suggest that both short- and long-term exercise performances can be improved with a reduction in training volume if speed endurance training is performed and that the Na(+)-K(+) pump plays a role in the control of K(+) homeostasis and in the development of fatigue during repeated high-intensity exercise.

TL;DR: Inactivity slows VO(2) kinetics in association with a reduction of muscle oxidative capacity and repeated high-intensity running performance and intensified training of already well-trained athletes can improve mechanical efficiency and repeated sprint performance.
