Clinical Trial Summary

The main objective of the study is to evaluate the physiological-biochemical effects of physical training under artificially altered climatic conditions (using a hypoxic thermoclimatic chamber) in particular to determine the effect of such training on exercise capacity and physiological response, including the effect of training in high-performance athletes. The study will evaluate the effects of physical training and the simultaneous application of hypoxia and heat/cold on aerobic and anaerobic capacity and the physiological response of the human body. The aim of the study is to find the most favourable environmental conditions for physical training in order to maximise physical performance.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Measurement of aerobic capacity (endurance)	Measurement of maximal oxygen uptake and determination of ventilatory thresholds (ergospirometry)	7 days before training and 7-10 days after the training. Training will last 4 weeks.
Primary	Measurement of anaerobic capacity	Measurement of maximal anaerobic power (Wingate Anaerobic Test)	7 days before training and 7-10 days after the training. Training will last 4 weeks.
Primary	Blood analysis	indicators of muscle damage, inflammatory markers (interleukins), oxidative stress, lactate concentration, tissue oxygenation, selected hormones (including erythropoietin) and enzymes, HIF (hypoxia inducible factor), selected vitamins, morphology (including reticulocytes), rheology and blood biochemistry	Before (10 min) and after (3 min) the first and last training. The training will last 4 weeks and will consist of 12 workouts
