Scientific monograph is a result of 2-year project work in researching physical activity habits in Slovenian children. This is one of the most important fields in assuring health in children and later adults. However, the current state is not so nice, implicating quick and successful interventions to allow the children enough physical activity. Scientific monograph is divided in ten scientific contributions that deals with integral analysis and initiatives for healthier life style in children.
Oxidative stress is often associated to inactivity-mediated muscle atrophy. We developed in erythrocytes a new minimally invasive method to determine peptide synthesis rate in human tissues. Application of the new method to skeletal muscle suggests that disuse atrophy is associated to oxidative stress induction as well as to compensatory activation of the glutathione system.
The aim of the study was to investigated the effect of 21 day horizontal bed rest on cutaneous cold and warm sensitivity and on behavioural temperature regulation. On the 1st and 22nd day of the bed rest we tested the cutaneous temperature sensitivity. Results indicate that there was a significant increase (p(0.05) in the minimal detectable warm stimulus. We conclude that although the ability to detect warm stimuli was reduced after bed rest, these changes appear to be too small to result in significant changes in the behavioural thermoregulatory responses.
Much can be done in this field if certain approaches are taken into consideration at the work planning stage. We can use analytical methods, such as the Method of Temporary Observations anda method for the evaluation of postural load during work, when positioning stressful lesson factors. This can be done in simple way in the field of time rationalisation as well as in the field of dimensional work adjustment to pupils. Research results show that by using a planned directed approach in this field, it is possible to achieve, a higher level of efficiency with normal levels of fatigue.
The aim of this study was to investigate the effects of endurance respiratory muscle training on endurance performance in normoxic and hypoxic conditions. In conclusion, the aforementioned endurance respiratory muscle training protocol enhances aerobic capacity in hypoxia without a concomitant enhancement of exercise performance. Endurance respiratory muscle training does not appear to be beneficial for improving performance under normoxic conditions.
