Complete raw and aggregated data for muscular performance and heart rate variability outcomes.

This Excel file contains the full dataset used in the analyses, structured into three sheets: “Muscular Performances”: individual pre- and post-intervention scores for maximal handgrip force (HGF, kg), push-ups completed (PU, units), plank hold duration (PL, seconds), and rating of perceived exertion (RPE). The sheet includes group allocation and descriptive statistics (means and standard deviations) for both the intervention and control groups. “HRV SU”: raw pre- and post-intervention heart rate variability (HRV) data recorded in the supine position, including time-domain and frequency-domain metrics (e.g., RMSSD, LF, HF, total power, LF/HF ratio), along with descriptive statistics. “HRV ST”: raw pre- and post-intervention HRV data recorded in the standing position, including the same HRV metrics as above, with individual values and group-level descriptive statistics. All variables are presented here in their original units exactly as collected during the experimental procedures.
