Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Subjects will undergo 5 whole body cryotherapy sessions (cryosauna) scheduled for a fixed time of day, performed daily for 5 days. The time of a single session will be 2-3 minutes, at a temperature of - 150°C. After each therapeutic session in the cryosauna, the subject will undergo a 15-minute warm-up on cardio equipment: stationary bike 5 minutes, rowing machine 5 minutes, treadmill 5 minutes. Adherence to the intervention will be monitored by a member of the study team.
Intervention code [1] 324896 0
Rehabilitation
Comparator / control treatment
The comparison group will also undergo a cryosauna treatment, without cold stimuli (the cryosauna will not be activated). Placebo therapy will be performed every day for 5 days, time analogous to the experimental group 2-3 minutes, at ambient temperature. After each therapeutic session in the cryosauna, the subject will undergo a 15-minute warm-up on cardio equipment: stationary bike 5 minutes, rowing machine 5 minutes, treadmill 5 minutes.
Control group
Placebo
