Effect of Hot Spring Therapy on Autonomic Nervous System and Exercise Performance During Altitude Training

19. Mai 2026 aktualisiert von: Ziyue Ou, Macao Polytechnic University

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

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.

Waffen und Interventionen

Teilnehmergruppe / Arm
Intervention / Behandlung
Aktiver Komparator: Natural Recovery Group
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.

Aktiver Komparator: Hot water immersion group
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 includes whole-body immersion up to the neck for 20 minutes, followed by a 10-minute rest before leaving the facility. Three times per week.

Maßnahmenbeschreibung
Zeitfenster
Heart Rate Variability (HRV) - RMSSD
Zeitfenster: Baselines were measured at the formal start of the experiment, at night during the 2nd, 3rd, and 4th weeks (post-intervention) after ascending the plateau, and post-tests were conducted one week after descending the plateau.
Root mean square of successive differences (RMSSD) between normal heartbeats, measured from a 5-minute seated ECG recording in a quiet, temperature-controlled (22-24°C) room after 15 minutes of rest. A higher RMSSD value indicates stronger parasympathetic activity. Unit: milliseconds (ms). Baseline, Week 2, Week 3 (post-intervention).
Baselines were measured at the formal start of the experiment, at night during the 2nd, 3rd, and 4th weeks (post-intervention) after ascending the plateau, and post-tests were conducted one week after descending the plateau.
1000-meter ergometer test.
Zeitfenster: Baseline measurements were taken before the official start of the experiment and during the 3rd and 4th weeks after ascending to the plateau.
Perform a 1000-meter all-out test on a rowing ergometer. Protocol: sprint at maximum effort to measure the shortest time. Record time. Units: seconds. Baseline, Week 3, Week 4.
Baseline measurements were taken before the official start of the experiment and during the 3rd and 4th weeks after ascending to the plateau.
