Description
PURPOSE: Characterize DSI scores and evaluate longitudinal changes in DSI and its constituent variables in collegiate Olympic weightlifters.
METHODS: Male and female weightlifters performed three trials of CMVJ and IMTP once per week during the final eight-week peaking period prior to competition. Mixed effects models were computed to identify week-to-week differences in DSI, CMVJ, and IMTP performance (α = 0.05). Cohen’s d effect sizes were calculated comparing between each week and baseline.
RESULTS: Significant changes in CMVJ peak propulsive force, IMTP peak force, and DSI were not detected throughout the testing period. Effect sizes were small for between-week comparisons in DSI, which decreased from baseline in Weeks 3, 5, and 7.
CONCLUSION: DSI did not significantly change across the eight-week period, although small magnitudes of between-week change were detected. These results suggest practitioners can perform less frequent DSI tests and still capture relevant strength and power profiles of their athletes.
