The objective of this research is to examine the effects of eccentric loading protocol across different time courses using two different conditions (105% repetition maximum and 125% repetition maximum) on a horizontal jump to potentiate activation. Fourteen (n = 14) participants (age 21 ± 1.5; height 171.4 ± 4.8 cm; body mass 65.9 ± 5.4 kg) performed standing broad jump (SBJ) trials on two separate test sessions at least 96 h apart. Each participant needed to undergo baseline (pre) of the jumping and was measured. Next, 105% (105RM) and 125% (125RM) leg presses were performed. After performing the leg press, subjects needed to perform SBJ at 3, 6, 9, and 12 min. The difference in SBJ performance between 105% (105RM) and 125% (125RM) has been analyzed for statistical significance. The statistical significance has been set at p > 0.05. There were significant differences across the time, p = 0.00 (p < 00.5) but no significant differences for both conditions, p =.85 (p > 0.05). However, the highest mean for 105% 1RM improvement was recorded at 6 min (T6 = 2.549) whereby for 125% 1RM, it was found at 3 min (T3 = 2.545) respectively. In conclusion, pre-conditioning loading at 105% 1RM and 125% 1RM is effective in improving SBJ performance at 3 and 6 min after loading. © 2020, Springer Nature Singapore Pte Ltd.
