The post-exercise glycogen recovery in tissues of trained rats.

The post-exercise glycogen recovery in myocardium, liver, diaphragm muscle and musculus biceps femoris was compared in untrained and trained rats. The glycogen level in myocardium of the trained rats was significantly higher than that in the untrained ones only immediately after the exercise-test and on the second day after the exercise. The liver glycogen levels on each of the examined post-exercise days were similar in both groups and did not differ from the control values. The post-exercise glycogen recovery in the diapraghm muscle of the untrained rats was also similar to that in the trained animals. In musculus bicpes femoris similar post-exercise supercompensation was found in both groups except on the second day when the glycogen level in the trained animals was significantly higher than that in the untrained ones. The results suggest that it is necessary to separate the effects of training from those of the last bout of exercise in the training program when the effect of training is examined.

Animals↗

[Maximal oxygen consumption and various physiological and somatic characteristics of students of the Białystok Medical Academy 1976-1977 and 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.

Isotonic capacitive transducer.

A transducer which changes the angle or elongation into voltage was designed and built. The principle of functioning of this device and technical details were described.

Effects of strychnine and picrotoxin on the activity of laryngeal and phrenic motoneurons during stimulation of vagus nerve.

Effects of strychnine and picrotoxin on the activity of laryngeal and phrenic motoneurons during stimulation of vagus nerve. Acta Physiol. Pol., 1977, 28 (1): 1-11. In paralyzed cats the activity of "single fibres" in the recurrent laryngeal nerve and phrenic nerve was recorded. The afferent part of the vagus nerve was stimulated electrically at a frequency of 200 Hz, the duration of one impulse was 1 msec and voltage values used were 0.1, 0.2 and 0.3 V. Stimulation was carried out in paralyzed animals and then after intravenous administration of strychnine 0.3 mg/kg and picrotoxin 1.0 mg/kg. Administration of the drugs was sufficient to induce in both nerves appearance of additional impulses of varying amplitude. Stimulation after administration of strychnine and picrotoxin caused partial inhibition of the activity of both nerves (less significant than before administration of drugs). The authors believe that the mechanisms of presynaptic and postsynaptic inhibition participate in the activity of nervous pathways conveying the inhibitory effect of the vagus nerve to the laryngeal and phrenic motor neurons.

The effect of estradiol on carbohydrate utilization during prolonged exercise in rats.

Female--castrated and male-sham operated rats were subjected to five hours of swimming. It was found that estradiol administered to female rats promotes a supercompensatory pattern of glycogen recovery in the myocardium at the end of the fifth hour of exercise. The hormone markedly delayed the glycogen mobilization from the liver during the first hour of swimming. Glycogen level in m. biceps femoris was essentially unchanged by estradiol both at rest and during exercise. Estradiol signifcantly increased glycogen level in m. masseter of resting rats. Hypoglycaemia developing at the end of the fifth hour of exercise was less pronounced in the estradiol--treated female rats than in the animals from other groups. It may be concluded that estradiol exerts a "sparing" effect on carbohydrate reserves during exercise in rats.
