Abstract
- Cabarkapa, D, Cabarkapa, DV, Philipp, NM, Knezevic, OM, Mirkov, DM, and Fry, AC. Pre-post practice changes in countermovement vertical jump force-time metrics in professional male basketball players. J Strength Cond Res 37(11): e609-e612, 2023--Despite the countermovement vertical jump (CVJ) being one of the most popular noninvasive and time-efficient methods for monitoring neuromuscular status, there is a lack of scientific literature focused on examining fatigue-induced alterations in performance in elite athletes. Thus, the purpose of this study was to examine changes in force-time metrics pre-post practice in professional male basketball players. Seventeen athletes competing in first-tier and second-tier national basketball leagues in Europe participated in this study. While standing on a uniaxial force plate sampling at 1,000 Hz, each athlete completed 3 CVJs pre-practice and post-practice. The practice consisted of individual and team shooting drills, position-specific player development drills, 5-on-0 offensive actions, and 5-on-5 play, including full-court transition (;2 hours). The findings reveal that pre-post practice changes in force-time metrics seemto be phase specific. Despite a trivial increase in eccentric mean force (920.4 6 100.2, 929.4 6 100.0 N), most changes were observed within the concentric phase of the CVJ. The concentric phase duration increased pre-post practice (0.233 6 0.027, 0.242 6 0.033 seconds), whereas concentric impulse (262.9618.8, 258.6621.6 N·s), peak velocity (2.9360.22, 2.8660.22m·s21), mean force (2052.46179.2, 2002.76188.2 N), mean power (3,165.56269.5, 3,030.96326.8W), and peak power (5,523.46607.3, 5,246.6 6663.7W) experienced a significant decrease. Moreover, alongside longer contraction time(0.66360.065, 0.68660.074 seconds), lower vertical jump height (41.0 6 6.8, 38.9 6 6.6 cm) and reactive strength index-modified (0.634 6 0.113, 0.579 6 0.111 m·s21) values were observed post-practice. Overall, these findings may allow practitioners to detect fatigue-induced changes in CVJ forcetime metrics in professional male basketball players that can ultimately improve the acute and longitudinal training-adaptation monitoring process.
