[Maximal oxygen consumption and various physiological and somatic characteristics of students of the Bialystok Medical Academy 1976-1977 and 1980-1986]. / Maksymalne pochlanianie tlenu oraz niektóre cechy fizjologiczne i somatyczne studentów Akademii Medycznej w Bialymstoku w latach 1976-1977, 1980-1986.

In students (men) of the 2nd course maximum oxygen uptake and some physiological features (rest systolic rate, vital lung capacity, the strength of flexors of both hands) and somatic ones (body weight, height) specific to a marked degree of physical fitness were assessed. The authors tried to find whether there exists a correlation between actual motion activity, cigarette smoking and self assessment of the health state by the students. The results of studies are presented in 16 tables and compared with the literature data.

Basing on clinical and radiological examinations as well as the perfusion of J125 iodoantipyrine in the patella it was found that 39% of paviors and 34.8% floorers exhibited changes resulting from overloading of that joint. Both groups revealed a high correlation between changes due to overloading and length of employment.

Effect of tenotomy and denervation on the early post-exercise glycogen recovery in skeletal muscles of the rat.

The role of passive tension and innervation in the early (1 and 3 h) post-exercise glycogen repletion was studied in different types (fast-twitch-glycolytic (FG), fast-twitch-oxidative-glycolytic (FOG) and slow-twitch-oxidative (SO) rat skeletal muscles. Immediately after a 30 min exercise the rats were anaesthetized and the muscles were subjected to the following surgical procedures: 1) left intact, 2) tenotomized, 3) denervated, 4) tenotomized and denervated. A group of resting rats was handled in the same way. It was found that tenotomy had no effect on glycogen levels in the muscle of resting rats. It, however, delayed the postexercise glycogen repletion in the FOG muscle. Denervation lowered the resting glycogen level only in the FG muscle. It resulted in further reduction of the glycogen level one hour after the exercise in this muscle. In the 3rd hour after the exercise the glycogen level in FG-denervated muscle was equal to that in the intact one. In the FOG and SO muscle denervation affected neither the resting glycogen level nor its recovery after the exercise.
