Abstract Details:

Purpose: From a strength-and-conditioning perspective, identifying exercise movements, stimuli, and assessments in the weight room that enhance sport-specific movements is critical. However, the ecological validity of many standard performance assessments and training movements is lacking in team sports. In basketball, players often run, or are in a whole-body movement pattern prior to jumping. Running vertical jump may provide the most ecological valid version of the vertical jump in basketball. The purpose of this study was to investigate the correlation between deadlift bar velocity metrics, running start vertical jumps, and traditional fixed-foot, countermovement jump reach verticals in Division II, NCAA male basketball athletes.

Methods: A sample of male collegiate basketball athletes (n = 14; aged = 21 ± 2 y; ht. = 186.1 ±10.4 cm; wt. = 85.1 ± 13.3 kg; BIA BF% = 11.3 ± 4.0 %) participated this study. Participants were asked to complete two, fixed-feet, countermovement jump reach verticals (VJ), two running start vertical jumps (rVJ), and a multiple-repetition hex-bar deadlift max as dictated by the strength and conditioning coach from which a bar velocity device was used to calculate peak force, peak power, peak velocity, mean power, and mean velocity during the deadlift. Both VJ attempts and then both rVJ attempts were completed during the same session, but each attempt was separated by at least one minute. The deadlift protocol took place on the following day, approximately 22 hours later. Peak force, peak power, and mean power were also calculated relative to each participant’s body mass and fat-free mass. Pearson correlations were run to investigate the relationships between vertical jump performances and bar velocity metrics.

Results: There was a strong correlation between VJ and rVJ (r= 0.95, VJ = 67.8 ± 9.1 cm; rVJ = 82.2 ± 10.4 cm). However, eVJ was weakly-to-moderately correlated with peak force (2047 ± 297 N) (r = 0.44), peak velocity (0.91 ± 0.18 m/s) (r = 0.23), mean velocity (0.52 ± 0.10 m/s) (r = 0.22), peak power (1698 ± 482 W) (r = 0.24), mean power (816 ± 244 W) (r = 0.20) for the deadlift. VJ was weakly-to-moderately correlated with peak force (N) (r = 0.31), peak velocity (m/s) (r = 0.29), mean velocity (m/s) (r = 0.23), peak power (W) (r = 0.31), mean power (W) (r = 0.25) of the deadlift. Alternatively, rVJ was moderately-to-strongly correlated with relative peak force (N/kg, r = 0.76; N/kg FFM, r = 0.75), relative peak power (W/kg, r = 0.41; W/kg FFM, r = 0.36), and relative mean power (W/kg, r = 0.56; W/kg FFM, r = 0.49 for the deadlift. Furthermore, VJ was moderately-to-strongly correlated with relative peak force (N/kg, r = 0.59; N/kg FFM, r = 0.54), relative peak power (W/kg, r = 0.56; W/kg FFM, r = 0.51), and relative mean power (W/kg, r = 0.42; W/kg FFM, r = 0.38) of the deadlift.

Conclusion: These data show rVJ and VJ are strongly correlated. Interestingly, the strength of the relationships between each version of the vertical jump and bar velocity or absolute power/force metrics from deadlift were moderate to low. However, when power and force were expressed relative to body mass or FFM, rVJ showed stronger relationships. PRACTICAL APPLICATIONS: The running vertical jump could be utilized as an ecologically valid performance metric in DII, male basketball players and correlates more with lower-body force and power production than the traditional, fixed-foot, countermovement jump reach verticals.
