“…Single-leg hop test aims to assess the integration of neuromuscular control, lower limb muscle strength, ability to perform movements that challenge knee stability, and to evaluate progress in knee rehabilitation. 1,2 Single-leg hop test is one of the predictors, with a good correlation, of dynamic knee stability. 1 From several studies done before, the single-leg hop test showed hope as a tool to predict whether patients with anterior cruciate ligament injury can return to high-level physical activity without experiencing further episodes of knee instability after non-operative rehabilitation.…”

Background: Functional activities mostly done in daily life such as jumping, walking, running, and stairs ascending-descending require dynamic stability of the knee. The knee joint dynamic stability is required to have effective and efficient functional activities and to avoid injury when performing them. It can be achieved by increasing muscle strength through strengthening exercises with the aim of balancing the agonist muscles (quadriceps femoris) and antagonist muscles (hamstring) using the agonist- antagonist paired set (APS) method.Aim: The aim of this study is to find out the effect of strengthening exercise using APS method, compared to traditional set (TS) method, on single-leg hop performance.Material and Methods: The subjects of this study were 14 untrained healthy men aged 18-40 years old divided into 2 intervention groups, APS group and TS group. The variable evaluated was the distance of single-leg hop (SLH).Results: The results of this study showed a significant increase in SLH distance in APS group (p=0.005) and TS group (p<0.001) with no significant difference between the two groups (p = 0.933).Conclusion: Quadriceps femoris and hamstring muscle strengthening exercises in both APS and TS methods increase SLH distance although there is no difference between them. The APS method has an advantage compared to the TS method in terms of a relatively shorter time with comparable results.

Post-activation performance enhancement (PAPE) is an improvement to voluntary muscle performance following a conditioning activity. There is evidence of fatigue resistance deficits in non-exercised muscles following unilateral fatiguing exercise of a contralateral muscle. The purpose of this study was to determine if a unilateral conditioning exercise protocol could induce PAPE in a contralateral, non-exercised muscle in young healthy adults. Thirty-two recreationally trained (n = 16) and athletically trained (n = 16) participants (16 males; age: 22.9 ± 2.03 years; height: 1.81 ± 0.06 m; weight: 82.8 ± 9.43 kg, and 16 females; age: 23.1 ± 2.80 years; height: 1.67 ± 0.07 m; weight: 66.4 ± 11.09 kg) were randomly allocated into two groups (dominant or non-dominant limb intervention). The experimental intervention, involved a conditioning exercise (4-repetitions of 5-seconds knee extension maximal voluntary isometric contractions: MVIC) with either the dominant (DOM) (n = 16) or non-dominant (ND) (n = 16) knee extensors with testing of the same (exercised) or contralateral (non-exercised) leg as well as a control (no conditioning exercise: n = 32) condition. Testing was performed before, 1-minute and 10-minutes after a high intensity, low volume, conditioning protocol (2 sets of 2x5-s MVIC). Pre- and post-testing included MVIC force and F100 (force developed in the first 100 ms: a proxy measure of rate of force development) and unilateral drop jump (DJ) height and contact time. There were no significant MVIC peak force or EMG nor DJ height or contact time interactions (intervention x limb dominance x time). The pre-test (0.50 ± 0.13) dominant leg MVIC F100 forces exceeded (p = 0.02) both post-test and post-10 min by a small magnitude 8.7% (d = 0.31). There was also a significant (p = 0.02) time x intervention leg x testing leg intervention, although it was observed that the control condition was as likely to demonstrate small to large magnitude changes as were the dominant and non-dominant legs. Following the conditioning activity, there was no significant evidence for non-local improvements (PAPE), or performance decreases.
