During whole body exercise in health, maximal oxygen uptake (V̇o2max) is typically attained at or immediately before the limit of tolerance (LoT). At the V̇o2max and LoT of incremental exercise, a fundamental, but unresolved, question is whether maximal evocable power can be increased above the task requirement, i.e., whether there is a "power reserve" at the LoT. Using an instantaneous switch fr...

Physiological testing of elite athletes requires the correct identification and assessment of sports-specific underlying factors. It is now recognised that performance in long-distance events is determined by maximal oxygen uptake (V(2 max)), energy cost of exercise and the maximal fractional utilisation of V(2 max) in any realised performance or as a corollary a set percentage of V(2 max) that...

parathyroid hormone (pth) is the major factor of calcium homeostasis. this hormone increases calcium uptake in intestines through stimulation of the active formation of vitamin d and eventually increases bone density. the aim of this study was to investigate the effect of one session of resistance and endurance activity on pth and alp in untrained young girls (mean age 21.9±1.23 yrs, height 161...
