[Effect of oxyhydromassage therapy on some physiological parameters].

The oxygen uptake of the living organism through the cardiorespiratory system is one of the most basic physiological procedures, and the capacity for the oxygen uptake is an important parameter of both the health and the performance of the living organism. During the past decade several experiments have been performed in order to elaborate a hyperoxygenisation method which avoids the respiratory system. The consumption of oxygen-rich mineral water and its application in hydromassage are also such methods.

Antioxidant status of interval-trained athletes in various sports.

Muscular exercise results in an increased production of free radicals and other forms of reactive oxygen species (ROS). Further, developing evidence implicates cytotoxins as an underlying etiology of exercise-induced stimuli in muscle redox status, which could result in muscle fatigue and/or injury. Two major classes of endogenous protective mechanisms (enzymatic and nonenzymatic antioxidants) work together to reduce the harmful effects of oxidants in the cell.

[Physiological characteristics of the health status of workers performing physical labor].

It was examined the physical fitness of 165 male laborer with a special respect to their physical performance. The research covered other factors, as well such as the somatic and circulatory parameters, the maximal oxygen uptake estimated by Astrand, i.e.

[Circulatory and respiratory parameters in children at cardiovascular risk].

Physical performance, pulse rate, blood pressure and respiratory functions (vital capacity, forced expiratory volume and maximal voluntary ventilation) in rest and during physical loading were studied in children of parents having had myocardial infarction under the age of 45. Children with normal and increased skinfold width, and with low resp. normal HDL-cholesterol levels were selected.

Study of the anaerobic metabolism during the preparation of runners.

The anaerobic threshold of 37 male and 16 female athletes was studied under laboratory conditions and in the field (4.0 mmol.l-1 lactic acid accumulation was considered as anaerobic threshold).
