简要总结
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.

研究组 & 干预措施
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±0.5°C) in a standardized indoor hot spring facility. The immersion protocol includes partial-body immersion up to the xiphoid process (lower chest) for 20 minutes, followed by a 10-minute rest before leaving the facility. Three times per week.
干预措施: Hot water immersion group (Behavioral)
Hot Spring Immersion Group
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 ± 0.5°C) in a standardized indoor hot spring facility. The immersion protocol includes partial-body immersion up to the xiphoid process (lower chest) for 20 minutes, performed three times per week, followed by a 10-minute rest before leaving the facility.
干预措施: hot spring immersion group (Behavioral)
Natural Recovery Group
Control group participants will undergo the same altitude training protocol (altitude 1600 meters) for 4 weeks. Participants underwent a 20-minute quiet seated rest at 16:00 on Tuesdays, Thursdays, and Saturdays, with ad libitum water consumption permitted and electronic devices prohibited.
