### DSWTT Treatment Program  
The water therapy and DSWTT programs administered in this study are presented in Table 2. After fatigue induced by exercise program progression, the subjects were asked to identify the effects of DSWTT program on fatigue recovery and muscle damage enzymes.  
The subjects in WEG actively participated in a water treatment program involving a tap-water bath (standard \(3\times 3\times 1.5\) m, horizontal \(\times\) vertical \(\times\) height) maintained at \(34\pm 1\)\({}^{\circ}\)C. The subjects in the DSWEG actively performed the same DSWTT program similar to the WEG but in a deep-sea water bath, which was maintained at \(34\pm 1\)\({}^{\circ}\)C (Figure 1). The subjects in the CG underwent dynamic recovery on the ground. The subjects of the study, which were first conducted by research director by group, were thoroughly educated in advance to perform the program with an accurate attitude on the DSWTT program (lower body, upper body, back body, whole body).  
The DSWTT program was used by reconstructing the items used by [PERSON] et al. The program was organized in the order of warm-up, treatment (lower body, upper body, back, body stretching and massage treatment), and cool-down phases. The time required for each phase was 2-5 min, lasting a total of 25 min. The DSWTT program consists of 7 lower body exercises, 8 upper body exercises, and 2 full body exercises. Each action was performed by an expert. The composition of the DSWTT program, treatment sites, and the time are shown in Table 2.

Table 1: General characteristics of subjects.  
In the DSWTT program environment, DSWEG was warmly heated with a regenerative boiler using the unique characteristics and properties of DSW with 34.03% salinity and pH 7.81 water depth of 0.5 m. The main elements included magnesium 1270 mg/L, calcium 367 mg/L, potassium 357 mg/L, sodium 11,033 mg/L, manganese 1.9 mg/L, zinc 0.68 mg/L, and iron 018 mg/L. WEG used tap water supplied by K-water to warm up. Considering the characteristics of this study, a special bathtub was installed in the room \(3\times 3\times 1.5\) m (horizontal \(\times\) vertical \(\times\) height), and the program was applied while maintaining a depth of \(1.2\pm 0.1\) m.
