dc.description.abstractBackground: The relationship between the external load lifted and movement velocity can be modeled by a simple linear regression, and the variables derived from the load-velocity (L-V) relationship were recently used to estimate the maximal neuromuscular capacities during 2 variants of the back-squat exercise. Hypothesis: The L-V relationship variables will be highly reliable and will be highly associated with the traditional tests commonly used to evaluate the maximal force and power. Study Design: Twenty-four male wrestlers performed 5 testing sessions (a 1-repetition maximum [1RM] session, and 4 experimental sessions [2 with the concentric-only back-squat and 2 with the eccentric-concentric back-squat]). Each experimental session consisted of performing 3 repetitions against 5 loads (45%-55%-65%-75%-85% of the 1RM), followed by single 1RM attempts. Level of Evidence: level 3. Methods: Individual L-V relationships were modeled from the mean velocity collected under all loading conditions from which the following 3 variables were calculated: load-axis intercept (L-0), velocity-axis intercept (v(0)), and area under the line (A(line) = L-0.v(0)/2). The back-squat 1RM strength and the maximum power determined as the apex of the power-velocity relationship (P-max) were also determined as traditional measures of maximal force and power capacities, respectively. Results: The between-session reliability was high for the A(line) (coefficient of variation [CV] range = 2.58%-4.37%; intraclass correlation coefficient [ICC] range = 0.98-0.99) and generally acceptable for L-0 and v(0) (CV range = 5.08%-9.01%; ICC range = 0.45-0.96). Regarding the concurrent validity, the correlations were very large between L-0 and the 1RM strength (r(range) = 0.87- 0.88) and nearly perfect between A(line) and P-max (r = 0.98-0.99). Conclusion: The load-velocity relationship variables can be obtained with a high reliability (L-0, v(0), and A(line)) and validity (L-0 and A(line)) during the back-squat exercise.en_US
