Methods: 29 subjects were assigned to either a velocity-deficit group (VD: n = 7; 71.3 \u00b1 6.1 y) or force-deficit group (LD: n = 22; 74.3 \u00b1 7.9 y) depending on the slopes of their force-velocity curves relative to a reference curve based on maximum force and velocity values from the sample. Initial loads were set at 60% 1RM. Changes in loads for targeting force or velocity deficits were determined by the ability to maintain either 70%, or 90%, respectively, of their peak power across 3 sets of 8 repetitions. Peak power values were determined using the values from the previous session. Subjects\u2019 powers were tested before and after training at loads of 40, 50, 60, 70, and 80% 1RM. A Wilcoxon\u2019s signed rank test was used to test the sample and the two groups for shifts in percent at which peak power was achieved (%1RMpp) by assessing the number of subjects with peak power at each load. <strong>Results:<\/strong> At baseline, mean %1RMpp values were: LPVD: 74.3 \u00b1 7.9%; LPFD: 68.7 \u00b1 9.8%; with no significant differences between groups (p &gt; .05). At post-test, %1RMpp was significantly different from baseline on the leg-press exercise for both groups, with the LPVD showing a larger effect size (p = .027, r = .591) than the LPFD (p = .021, r = .357)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Purpose: This study examined the impact of 3 months of velocity-based training on leg-press strength, power, and load-velocity relationships in older adults demonstrating either a velocity or force deficit.
