Šildymo ir šaldymo poveikis raumens nuovargiui ir atsigavimui, jo priklausomumas nuo lyties ir raumens susitraukimo greičio / The effect of warming and cooling on muscle fatigue and recovery depending on gender and muscle contraction rate

The majority of physiological processes and various other processes taking place in the body are closely related to changes in body temperature (Shellock & Prentince, 1985; Bennett, 1990). The temperature of the human body is constant throughout one’s life. It is approximately 37ºC and it constantly adjusts itself to changes in environment, relative air humidity, the level of radiation, atmosphere pressure and thermo isolation. During long-term physical load, in case of illness or in conditions of extreme body temperature may be in the range from 32ºC to 40ºC or even more (Wilmore & Costill, 2004).
It could be hypothesized therefore that the muscle warmed prior to the load to be undertaken, when the leg is extended and flexed in the knee joint at high (500, 450o / s) and average (180o / s) speed depending on gender will increase muscle force and muscle capacity to a greater extent than the cooled muscle, but after lowering the temperature muscle resistance to fatigue will increase.
Though considerable research has been done already certain questions still remain to be cleared up, namely:
1. how warming affects muscle fatigue and recovery of female knee extensors and flexors when the leg is being flexed and extended in the knee joint at the fixed 500o / s speed;
2. how muscle contraction function of female and male knee extensors and flexors depends on temperature when the leg is being flexed and extended in the knee joint at the fixed 450o / s and 180o / s peed.
Though there... [to full text]
