This study aimed to investigate the relationship between RSImod and RSI in various jumping movements in 60 female university volleyball players and to evaluate the validity of these indices in performance evaluation. Spike jumps, block jumps, counter movement jumps, and rebound jumps were measured as jumping movements, and RSImod and RSI were calculated using an Enode device. As a result, a moderate correlation was found between spike jumps and counter movement jump RSImod (r = 0.497; p < 0.001), and between block jumps and counter movement jump RSImod (r = 0.433; p < 0.05). However, compared with previous studies targeting male players, it was revealed that the correlation coefficients were lower in female players.
