... to stress-enhanced anti-oxidative defence mechanisms and the nature of responses to hormones, restricted diet and lower environmental temperature corroborate the concept. On the other hand neither the increase in mortality rate and accumulation of lipofuscin nor the reproductive senility have been shown...

... span with temperature, rate of energy expenditure, growth rate and activity. It is concluded that the theory rests on a weak theoretical basis and even on a series of highly nonplausible assumptions and that, furthermore, the evidence experimentally accumulated is, with a few odd exceptions...

... for 30 min produced a 3.4°C rise in muscle temperature (Tm) and was associated with a significant (p < 0.001) reduction in maximal time to peak tension and half relaxation time of the twitch, but was without affect on maximal twitch, tetanic (20 and 50 Hz) and voluntary tensions. However, at 10 Hz...
