Effect of Hot Spring Therapy on Cognitive Function Recovery During Altitude Training
2026년 5월 19일 업데이트: Ziyue Ou, Macao Polytechnic University
A Randomized Controlled Trial Investigating the Effects of Balneotherapy on Cognitive Performance, Cerebral Hemodynamics, and Exercise Capacity in Healthy Adults Undergoing Simulated Altitude Training
This randomized controlled trial aims to investigate the effects of hot spring bath therapy on cognitive function recovery, cerebral hemodynamics, and athletic performance in athletes undergoing altitude training.
Participants will be randomly assigned to either a hot spring intervention group, a hot water control group, or a blank control group.
The hot spring intervention group receives hot spring baths (38°C, 20 minutes) combined with altitude training; the hot water control group receives hot water baths (38°C, 20 minutes) combined with altitude training; and the blank control group receives standard recovery procedures combined with altitude training.
Primary outcome measures include cognitive performance assessments (Stroop test, psychomotor vigilance test) and cerebral hemodynamic indicators (functional near-infrared spectroscopy, transcranial Doppler ultrasound).
Secondary outcomes included exercise capacity (maximal oxygen uptake, triathlon performance, 500-meter test), blood lactate, and hematological parameters (white blood cells, neutrophils, platelets).
These findings may provide evidence for non-pharmacological interventions to enhance cognitive recovery and brain adaptation during altitude training.

활성 비교기: 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.
