It has previously been shown that a loaded warm-up may improve power performances. We examined the acute effects of loaded dynamic warm-up on change of direction speed (CODS), which had not been previously investigated. Eight elite badminton players participated in three sessions during which they performed vertical countermovement jump and CODS tests before and after undertaking the dynamic warm-up. The three warm-up conditions involved wearing a weighted vest (a) equivalent to 5% body mass, (b) equivalent to 10% body mass, and (c) a control where a weighted vest was not worn. Vertical jump and CODS performances were then tested at 15 seconds and 2, 4, and 6 minutes post warm-up. Vertical jump and CODS significantly improved following all warm-up conditions (P < .05). Post warm-up vertical jump performance was not different between conditions (P = .430). Post warm-up CODS was significantly faster following the 5% (P = .02) and 10% (P < .001) loaded conditions compared with the control condition. In addition, peak CODS test performances, independent of recovery time, were faster than the control condition following the 10% loaded condition (P = .012). In conclusion, the current study demonstrates that a loaded warm-up augmented CODS, but not vertical jump performance, in elite badminton players.
此前已有研究表明，负重热身可能会提高力量表现。我们研究了负重动态热身对变向速度（CODS）的急性影响，这在之前尚未被研究过。八名精英羽毛球运动员参加了三个阶段的测试，在进行动态热身之前和之后，他们进行了垂直纵跳和CODS测试。三种热身条件包括穿着（a）相当于体重5%的负重背心、（b）相当于体重10%的负重背心，以及（c）不穿负重背心的对照条件。然后在热身结束后15秒、2分钟、4分钟和6分钟测试垂直纵跳和CODS表现。在所有热身条件下，垂直纵跳和CODS均显著提高（P < 0.05）。不同条件下热身结束后的垂直纵跳表现没有差异（P = 0.430）。与对照条件相比，在5%（P = 0.02）和10%（P < 0.001）负重条件下，热身结束后的CODS明显更快。此外，在10%负重条件下，无论恢复时间如何，CODS测试的峰值表现均快于对照条件（P = 0.012）。总之，当前研究表明，在精英羽毛球运动员中，负重热身增强了CODS，但没有增强垂直纵跳表现。
