Abstract

This research examined the priming effects of back squats (BS) and rear foot elevated split squats (RFESS) on bilateral countermovement jumps (CMJ), right single-leg countermovement jumps (RCMJ), and left single-leg countermovement jumps (LCMJ) in well-trained athletes. Seventeen male participants, all trained in competitive team sports including basketball, football, and handball (age: 24.2 ± 5.2 years; weight: 72.6 ± 8.2 kg; 1RM BS: 122.79 ± 11.7 kg; 1RM RFESS: 78.26 ± 10.9 kg) performed 3 sets of 3 repetitions of both exercises at 80% of their 1RM as conditioning activities (CAs), before executing CMJ, RCMJ & LCMJ at 0, 4, 8, and 12 minutes post-CA. Although no significant differences were noted between the two CAs, significant improvements were observed after BS at 4 minutes for CMJ (+14.4 %, 6.1cm), RCMJ (+10.4 %, 2.0cm), and LCMJ (+13.7%, 2.6cm), as well as at 8 minutes for CMJ (+8.4 %, 3.5 cm), RCMJ (+11.3%, 2.1cm), and LCMJ (+12.4%, 2.4cm). For the RFESS, significant results were observed at 4 minutes for CMJ (+7.9%, 3.4cm), RCMJ (+11.2%, 2.2cm), and LCMJ (13.7%, 2.5cm), and at 8 minutes for CMJ (+7.1%, 2.9cm), RCMJ (+11.2%, 2.1cm), and LCMJ (+10.6 %, 2.0cm). These results demonstrate that both BS and RFESS effectively prime bilateral and unilateral vertical jumping performance at 4 and 8 minutes post-CAs. Practitioners can use either option to enhance jump performance in training or before competition. However, for bilateral jumps at 4 minutes post-CA, BS shows greater percentage improvements than RFESS. Practitioners should exercise caution when applying the priming effect in contrasting training scenarios.
