Effects of endurance exercise and half-bath on body composition, cardiorespiratory system, and arterial pulse wave velocity in men with intellectual disabilities.

The study included only 24 men, and all had intellectual disability without other medical disabilities, so results may not apply to women or people with additional conditions. The paper does not report a primary outcome or blinding. The half-bath group did not show the same oxygen uptake or heart rate increases as the exercise group, so it cannot be treated as an exercise substitute. The explanation that heat and cooling increased blood supply and metabolism is an assumption, not a measured mechanism.

Do not conclude that half-bath alone improves heart and breathing measures. The study showed clear increases in oxygen uptake and heart rate only in the aerobic exercise group.
