UNASSIGNED: The purpose of this study was to determine if grip strength was a risk factor for injury. It was hypothesized that pitchers with weaker grip strength would have a higher likelihood of sustaining a shoulder or elbow injury compared with pitchers with stronger grip strength.
UNASSIGNED: Case-control study; Level of evidence, 3.
UNASSIGNED: All professional pitchers from a single Major League Baseball organization were included. Dominant and nondominant grip strength were measured after each pitching outing throughout the 2022 season. Injuries over the course of the season were recorded, and data were compared between pitchers who sustained a shoulder or elbow injury and those who did not.
UNASSIGNED: Overall, 213 pitchers were included, of whom 53 (24.9%) sustained a shoulder or elbow injury during the season. The mean grip strength for all pitchers was 144.0 ± 20.8 lb (65.3 ± 9.4 kg). The mean dominant-arm grip strength was 142.6 ± 20.8 lb (64.7 ± 9.4 kg) for pitchers who did not sustain a shoulder or elbow injury and 148.2 ± 20.9 lb (67.2 ± 9.5 kg) for pitchers who did sustain an injury, with no significant group difference in grip strength (P > .05). Furthermore, there were no significant differences in change in grip strength over the course of the season between the groups.
UNASSIGNED: There was no significant difference in mean grip strength or change in grip strength over the course of a single season between professional baseball pitchers who sustained a shoulder or elbow injury and those who did not.
■这项研究的目的是确定握力是否是受伤的危险因素。据推测,与握力较强的投手相比,握力较弱的投手承受肩部或肘部受伤的可能性更高。
■病例对照研究;证据水平,3.
■包括来自单个美国职棒大联盟组织的所有职业投手。在整个2022赛季的每次投球后,都测量了主要和非主要的握力。记录了整个赛季的受伤情况,并比较了肩肘受伤的投手和未受伤的投手之间的数据。
■总的来说,包括213个投手,其中53人(24.9%)在本赛季肩部或肘部受伤。所有投手的平均握力为144.0±20.8磅(65.3±9.4千克)。对于没有遭受肩部或肘部伤害的投手,平均优势臂握力为142.6±20.8磅(64.7±9.4千克),对于遭受伤害的投手,平均优势臂握力为148.2±20.9磅(67.2±9.5千克)。两组握力比较差异无统计学意义(P>.05)。此外,在整个季节中,两组间握力的变化没有显著差异.
■在一个赛季中,遭受肩部或肘部受伤的职业棒球投手与没有受伤的职业棒球投手之间的平均握力或握力变化没有显着差异。
