The possibility of local reduction of subcutaneous fatty tissue was investigated in the project discussed in this article. Only one male participated in the experiment. During the experiment the participant trained his abdomen doing additional cardio training for two weeks, while in the following two weeks the abdomen was not trained at all. Instead of abdomen training, only cardio training was performed. This was repeated until the end of the experiment which lasted 9 weeks. The sum of thickness of all 7 observed skin folds was counted. Then, percentage of thickness of abdomen skin folds in relation to all skin folds was calculated. Each successive measurement was compared with the previous one to assess the decrease or increase of abdomen skin fold percentage in relation to all measured skin folds. We put the decreases and increases into a contingency table and calculated probability by using the Fisher’s exact test. Statistical significance was determined at 0.05 level. The local reduction of subcutaneous fatty tissue at abdomen was proven. However, the problem needs more scientific results to conclude this question completely.

We have examined the effect of 5 week cycling endurance training program on the sarco(endo)plasmic reticulum Ca2+ ATPase isoforms (SERCA1 and 2) and myosin heavy chain (MyHC) in the vastus lateralis muscle as well as on the oxygen uptake to power output ratio (VO2/PO) during incremental cycling. Fifteen untrained men performed an incremental cycling exercise until exhaustion before and after moderate intensity training. Muscle biopsies were taken from vastus lateralis before and after training program. Training resulted in higher (P = 0.048) maximal oxygen uptake (VO2max) as well as in higher power output reached at VO2max (P = 0.0001). Moreover, lower (P = 0.02) VO2/PO ratio determined during incremental moderate intensity cycling (i.e. 30-120 W) as well as lower (P = 0.003) VO2/PO ratio reached at VO2max were observed after the training. A significant down regulation of SERCA2 protein (P = 0.03) and tendency (P = 0.055) to lower SERCA1 content accompanied by lower (P<10-4) plasma thyroid hormone concentration, with no changes (P = 0.67) in MyHC composition in vastus lateralis muscle were found after training. We have concluded that the increase in mechanical efficiency of cycling occurring during first weeks of endurance training is not related to changes in MyHC composition but it may be due to down-regulation of SERCA pumps.

Both intensive training and bed confinement impair orthostatic tolerance, however, moderate training may exert beneficial effect on cardiovascular adjustment to gravitational stimuli. It was hypothesized that moderate training attenuates effects of bed rest. To test this assumption 24 healthy male volunteers aged 20.8±0.9 yrs were subjected to 6° head down bed rest (HDBR) for 3 days before and after 6 weeks of moderate endurance training. Before and after HDBR graded LBNP tests (-15, -30, -50 mmHg) were performed. During these tests heart rate (HR), stroke volume (SV), blood pressure (BP), plasma catecholamines, ACTH, adrenomedullin, atrial natriuretic peptide, plasma renin activity (PRA) and hematocrit were determined. HDBR did not systematically influence LBNP tolerance up to -50 mmHg, but it enhanced rates of reduction of SV, cardiac output and systolic BP and increased elevations of HR and PRA. Training did not alter significantly effects of HDBR on LBNP-induced changes in HR, SV, CO and TPR but it attenuated decrease in systolic BP and diminished increases in plasma noradrenaline and PRA. In conclusion, training has negligible effect on the HDBR-induced changes in central hemodynamics during LBNP but may increase vascular sensitivity to some vasoconstricting factors.

Twelve male, sedentary volunteers (22.0 ± 0.7 yrs) were submitted to three weeks of a bicycle ergometer training, consisting of 45 min exercise (at 70% VO2max), 4 times in the first week and 3 times in the next 2 weeks. They performed four incremental exercise tests with the power output increased by 50 W every 3 min until volitional exhaustion: two before training (C1 and C2), and after one (T1) and three (T3) weeks of training. Before and after each load the plasma noradrenaline (NA), adrenaline (A) and blood lactate (LA) concentrations were determined in venous blood samples as well as plasma growth hormone (HGH) and cortisol concentrations before and at the end of exercise. A decrease in NA concentration was found already after 1 week of training at power output of 100 W (p<0.01) and 200 W (p<0.05). Similar decline was maintained after 3 weeks of training. No significant training-induced differences in plasma A concentration were found, however, the thresholds for both catecholamines were significantly shifted towards higher values after 3 weeks of training. One week of training caused a decrease in the pre-exercise (p<0.01), as well as post-exercise (p<0.05) plasma cortisol and HGH concentrations. It was concluded that endurance training induced a decrease in HGH, cortisol and NA concentration already after one week of training. A decline of pre-exercise plasma HGH and cortisol levels with time of experiment may, in part, indicate familiarization to exercise protocol.

The sphingomyelin signalling pathway has been shown to function in different skeletal muscle types. The aim of the present study was to examine the effect of endurance training on the functioning of the pathway in the muscles. The experiments were carried out on two groups of male Wistar rats: sedentary and trained for six weeks. 24h after cessation of the training rats were anaesthetized and samples of the soleus, red and white section of the gastrocnemius were taken. The content and composition of sphingomyelin-fatty acids and ceramide - fatty acids was determined by means of gas-liquid chromatography. The content of sphingosine and sphinganine was determined by means of high-pressure liquid chromatography. The activity of neutral Mg++-dependent sphingomyelinase was determined spectophotometrically using trinitrophenylaminolauroyl-sphingomyelin as the substrate. It has been found that training reduces the total content of sphingomyelin- and ceramide-fatty acids, increases the content of sphinganine and does not affect the content of sphingosine in individual muscle types. The activity of the enzyme in the muscles is also elevated. It is concluded that training affects functioning of the sphingomyelin -signalling pathway in skeletal muscles. The reduction in the content of ceramide may contribute to elevation in glucose uptake in skeletal muscles observed after training.

Endurance training is considered as a factor impairing orthostatic tolerance although an improvement and lack of effect have been also reported. The mechanisms of the changes and their relation to initial tolerance of orthostasis are not clear. In the present study, effect of moderate running training on hemodynamic and neurohormonal changes during LBNP, a laboratory test simulating orthostasis, was investigated in subjects with high (HT) and low (LT) tolerance of LBNP. Twenty four male, healthy subjects were submitted to graded LBNP (-15, -30 and -50 mmHg) before and after training. During each test heart rate (HR), stroke volume (SV) and blood pressure, plasma catecholamines, ACTH, adrenomedullin, atrial natriuretic peptide, and renin activity were determined. Basing on initial test, 13 subjects who withstood LBNP at -50 mmHg for 10 min were allocated into HT group and 11 subjects who earlier showed presyncopal symptoms to LT group. Training improved LBNP tolerance in six LT subjects. This was associated with attenuated rate of HR increase and SV decline (before training, at -30 mmHg DHR was 21 ± 4 beats/min and SV – -36± 8 ml while after training the respective values were 8 ± 4 beats/min and -11± 6 ml). No differences in hemodynamic response were found in HT subjects and those from LT group whose LBNP tolerance was unchanged. In neither group training affected neurohormonal changes except inhibition of plasma ACTH rise in subjects with improvement of LBNP tolerance. It is concluded that some subjects with low orthostatic tolerance may benefit from moderate training due to improvement of cardiac function regulation.
