摘要

背景:北欧腿筋运动(NHE)有助于预防腿筋拉伤。假设/目的:本研究旨在探讨北欧式腿筋运动中的偏心力与举重单次最大重量之间的关系。假设 NHE 时的偏心力与负重举的单次最大重量(1RM)相关:方法:招募无腿筋撕裂史的健康学生橄榄球运动员参加。测量两条腿在 NHE 期间的偏心峰值力(即握腿部位的垂直峰值力),同时逐渐前倾至俯卧姿势,持续三秒钟。负重举起的 1RM 是根据负重举起三次所能举起的重量(x 千克),用估算公式(x 千克/0.93)计算得出的。使用斯皮尔曼等级相关系数检验了NHE期间左右偏心力峰值、左右总力量和负重举的1RM之间的相关性,所有数值均根据体重进行了校正:在NHE过程中,左右腿的偏心力峰值和双腿的偏心力总峰值分别为3.8±1.1 N/BM、3.8±1.2 N/BM和7.6±2.1 N/BM。举重的 1RM 为 1.9 ± 0.3 kg/BM。研究发现,负重举的 1RM 与左右腿的偏心力峰值以及双腿的偏心力总峰值之间存在微弱的相关性(r = 0.34-0.37):本研究揭示了NHE时的偏心力峰值与负重举的1RM之间的微弱相关性。

Relationship between Peak Eccentric Force during the Nordic Hamstring Exercise and One Repetition Maximum Deadlift Performance.

Background: The Nordic hamstring exercise (NHE) is useful for preventing hamstring strain injuries. However, its adoption rates in the sports field are currently low, necessitating a safe and efficient introduction.

Hypothesis/purpose: The purpose was to examine the relationship between the eccentric force during the NHE and the one repetition maximum of deadlift. It was hypothesized that the eccentric force during the NHE would be correlated with the one repetition maximum (1RM) of the deadlift.

Study design: Cross-sectional study.

Methods: Healthy student rugby players with no history of hamstring tears were recruited to participate. The peak eccentric forces during the NHE, which is the vertical peak force on the part holding the leg, were measured in both legs, while gradually leaning forward to a prone position over three seconds. The 1RM of deadlift was calculated from the weight that could be raised three times during a deadlift (x kg) using the estimated formula (x kg / 0.93). The correlation between the left and right peak eccentric forces during the NHE, the total left and right forces, and the 1RM of the deadlift was examined using Spearman's rank correlation coefficient, with all values corrected for body mass.

Results: During the NHE, the peak eccentric force of the right and left legs and the total peak eccentric force of both legs were 3.8 ± 1.1 N/BM, 3.8 ± 1.2 N/BM, and 7.6 ± 2.1 N/BM, respectively. The 1RM of deadlift was 1.9 ± 0.3 kg/BM. Weak correlations (r = 0.34-0.37) were found between the 1RM of the deadlift and the peak eccentric force in the right and left legs and the total peak eccentric force of both legs.

Conclusion: The present study revealed a weak correlation between the peak eccentric force during the NHE and 1RM of deadlift.

Level of evidence: 2c.
