  1. Data are Spearman’s ρ correlation coefficients, with 95% confidence intervals across 100 Bootstrap samples are presented.
  2. BP 1RM a one-repetition maximal value for bench press, BP power the maximal power output during the 40% of 1RM in a bench press.
  3. *p < 0.05, **p < 0.001. A p-value < 0.05 indicates statistical significance, while a p-value < 0.01 represents strong statistical significance.
