This study examined the relationship between subjective ratings of overall wellness and neuromuscular performance throughout a 6-week intensive offseason strength and conditioning program. Thirty experienced NCAA Division II baseball players completed all phases of the program. A comprehensive wellness rating and 5 countermovement jumps (CMJ5) were measured and averaged for 4 phases of training. Pre-and post-testing measures of strength and speed also were evaluated. Internal consistency of the wellness rating for each phase ranged α = 0.77-0.92, and CMJ5 velocities had decent consistency (ICCα = 0.88, TE = 0.19 m·s-1, CV = 5.90%). The training program evoked significant (p < 0.01) improvements in front squats (d = 0.55), trap bar deadlifts (d = 0.62), chin ups (d = 0.39), 30-yd dash (d = 0.39), with no change in the 300-yd dash (p > 0.05), where d is the treatment effect size. Average CMJ5 velocities (m·s-1 ) were similar for the preparation phase (1.90 ± 0.25), eccentric phase (1.91 ± 0.28), strength & power phase (1.91 ± 0.24), and recovery phase (1.91 ± 0.30; F = 0.04, p = 0.99, ηp 2 = 0.001). No significant correlations were observed for preor post-testing measures of wellness ratings in comparison to any performance measures, including a composite standardized score from each performance test at pre-testing (r = 0.22, p = 0.26). The CMJ5 exhibited too high of a typical error to determine a change in neuromuscular status. Additionally, the wellness rating did not reflect changes in relation to performance.
