TLDR
The dynamics of lactate accumulation in working muscle was studied in three subjects performing maximal bicycle exercise of 2, 6, and 16 min duration.Abstract:
The dynamics of lactate accumulation in working muscle was studied in three subjects performing maximal bicycle exercise of 2, 6, and 16 min duration. In separate experiments, the two longer maxima...read more

Adaptations of muscular tissue to training.
TL;DR: E XERCISE-TRAINING, if sufficiently vigorous, brings about adaptive increases in performance capacity made possible by adaptations in the skeletal muscles, in the cardiovascular system, and in the autonomic nervous system.
Journal ArticleDOI
The role of emotions on pacing strategies and performance in middle and long duration sport events.
TL;DR: It is suggested that training sessions teach the athlete to select optimal pacing strategies by associating a level of emotion with the ability to maintain that pace for exercise of different durations, which is then adopted in future events.

TL;DR: Changes in skeletal muscle in five morbidly obese female subjects who had biopsies of the gastrocnemius muscle after hypocaloric dieting resulted in a significant increase in the intracellular muscle calcium content, which may account for the observed changes in muscle function.

Sleep as a Restorative Process and a Theory to Explain Why
TL;DR: It is proposed in this chapter that it is the differing energy demands of the activity/inactivity rhythm that chiefly determine the degradative/synthetic rhythm, such that the synthetic period inevitably coincides with the inactive or rest period.
Journal ArticleDOI
The failing inspiratory muscles under normoxic and hypoxic conditions.
TL;DR: It was concluded that respiratory muscles, working against high inspiratory resistances, fall as pressure generators sooner during low oxygen breathing, resulting in a shorter endurance time, a faster rate in the shift of the electromyographic power spectrum, and a greater rate of increase in blood lactate concentrations.
