A Randomized Controlled Trial to Investigate the Effects of Balneotherapy on Cardiac Autonomic Regulation and Exercise Performance in Healthy Adolescents Undergoing Real 1600-meter Altitude Training and Athlete Training.
In Brief
A clinical study evaluating Control Group：Natural Recovery, Hot water immersion group, and 1 other intervention for Altitude Training Adaptation and 4 related conditions. Completed, enrolled 27 participants across 1 site.
Detailed Summary
This randomized controlled trial aims to investigate the effects of balneotherapy (hot spring bathing) on cardiac autonomic nervous system function and exercise performance in healthy athletes undergoing high-altitude training. Participants will be randomly assigned to the intervention group (receiving hot spring baths three times per week (38°C, 20 minutes) combined with high-altitude training), the control group (receiving routine recovery protocols combined with high-altitude training), or the hot water immersion group (receiving hot water baths three times per week (38°C, 20 minutes) combined with high-altitude training). Primary outcome measures include heart rate variability (HRV) indices and exercise performance indicators. Secondary outcomes include blood lactate, peripheral oxygen saturation (SpO2), and subjective fatigue. These findings may provide evidence for non-pharmacological interventions to enhance high-altitude training adaptation and exercise recovery.
Study Details
Timeline
Arms & Interventions
Control group participants will undergo the same altitude training protocol (altitude 1600 meters) for 4 weeks. After each training session, participants will receive standard recovery procedures, including 20 minutes of passive rest in a thermoneutral environment (room temperature 24°C), supplemented with mild hydration and self-selected stretching. No hydrothermal intervention will be provided.
The hot water immersion group will undergo a 4-week altitude training at 1600 meters above sea level. Subjects will receive a 20-minute hot water immersion (daily tap water, 38°C±1°C) in a standardized indoor hot spring facility. The immersion protocol involves soaking the body below the chest for 20 minutes, followed by a 10-minute rest before leaving the facility. Three times per week.
The hot spring immersion group will undergo a 4-week high-altitude training at an altitude of 1600 meters. Subjects will receive a 20-minute hot spring therapy (natural hot spring water, 38°C ± 1°C) in a standardized indoor hot spring facility. The immersion protocol involves soaking the body below the chest for 20 minutes, followed by a 10-minute rest before leaving the facility. Three times per week.
