Aktywny 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.

Aktywny 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 involves soaking the body below the chest for 20 minutes, followed by a 10-minute rest before leaving the facility.
Three times per week.

Heart Rate Variability (HRV) - RMSSD
Ramy czasowe: 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.

HRV - SDNN
Ramy czasowe: 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.
|
Standard deviation of NN intervals (normal-to-normal R-R intervals), reflecting overall autonomic modulation.
Unit: milliseconds (ms).
Baseline, Week 2, Week 3, Week4, post-tests
|
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.

|
Peripheral Oxygen Saturation (SpO2)
Ramy czasowe: one month.
|
Resting peripheral oxygen saturation measured via fingertip pulse oximeter after 10 minutes of seated rest.
Unit: percentage (%)
|
one month.
|
|
Rating of Perceived Exertion (RPE)
Ramy czasowe: one month.
|
Borg 6-20 scale rating of perceived exertion recorded immediately after each training session.
Higher scores indicate greater subjective effort.
Unit: score (6-20).
Daily during intervention
|
one month.
|
|
Maximum oxygen uptake
Ramy czasowe: The baseline measurement was taken before the official start of the experiment, and the post-test was conducted one week after descending from the plateau.
|
Testing maximum oxygen uptake on a rowing ergometer combined with a cardiopulmonary function tester.
Protocol: Using a graded incremental protocol to test maximal oxygen uptake (VO2max).
Units: mL·kg-1 ·min-1.
Baseline, Week 5.
|
The baseline measurement was taken before the official start of the experiment, and the post-test was conducted one week after descending from the plateau.
|
|
30-second anaerobic power.
Ramy czasowe: The tests are scheduled before entering the plateau (baseline), during the 4th week of plateau training, and 1 week after leaving the plateau.
|
Perform a 30-s all-out test on a rowing ergometer.
Protocol: sprint at maximum effort to measure the 30-second average power.
Record power.
Units: watt.
Baseline, Week 4,1 week after altitude training.
|
The tests are scheduled before entering the plateau (baseline), during the 4th week of plateau training, and 1 week after leaving the plateau.
