The Impact of Running-Based and Drop Jumping Interval Interventions on Cardiorespiratory Fitness and Anaerobic Power of Collegiate Volleyball Players: A Comparative Analysis of Inter-Individual Variability in the Adaptive Responses

Figure 4. Residuals in individual changes in response to interval jumping and interval running over the training period in peak power output (PPO), average power output (APO), change of direction (COD) squat jump (SJ), and countermovement jump (CMJ). Individual residuals in percentage change are shown by triangles, and mean group residuals in percentage change is shown by horizontal bars. † Significantly greater changes than interval running.
