A Randomized Controlled Trial Investigating the Effects of Balneotherapy on Cardiac Autonomic Modulation and Athletic Performance in Healthy Adolescents Undergoing Simulated Altitude Training

What this Trial Is About

Researchers are evaluating the effects of balneotherapy, or hot spring bathing, on the heart's autonomic nervous system and exercise performance in healthy young athletes aged 11 to 17 undergoing high-altitude training. The goal is to understand how these therapies influence adaptation to altitude and recovery during exercise. This randomized controlled trial compares hot spring therapy, hot water immersion, and routine recovery methods. Participants will be divided into three groups: one receiving natural recovery with passive rest after altitude training at 1600 meters, one receiving hot water immersion baths at 38°C for 20 minutes three times per week, and one receiving natural hot spring baths under the same conditions. Each intervention lasts 4 weeks during the altitude training period. Both immersion groups include a 10-minute rest after bathing. Throughout the study, researchers will measure heart rate variability indices and exercise performance through a 1000-meter ergometer test at multiple time points during and after the training period. Secondary measures include blood lactate levels, oxygen saturation, and perceived fatigue. Monitoring occurs during and one month after the interventions to assess recovery and adaptation effects.
