Injuries in professional baseball players have become exceedingly common. Efforts to mitigate injury risk have focused on the kinetic chain, shoulder motion, and so forth. It is unclear whether grip strength is related to injury risk in professional baseball pitchers.
PURPOSE/HYPOTHESIS: 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.
Case-control study; Level of evidence, 3.
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.
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 ( > .05). Furthermore, there were no significant differences in change in grip strength over the course of the season between the groups.
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.
职业棒球运动员受伤已变得极为常见。减轻受伤风险的努力主要集中在动力链、肩部运动等方面。目前尚不清楚握力是否与职业棒球投手的受伤风险相关。
目的/假设：本研究的目的是确定握力是否为受伤的风险因素。研究假设为，与握力较强的投手相比，握力较弱的投手肩部或肘部受伤的可能性更高。
病例对照研究；证据等级为3级。
纳入来自一个美国职业棒球大联盟组织的所有职业投手。在2022赛季的每次投球训练后，测量其优势手和非优势手的握力。记录该赛季期间的受伤情况，并对肩部或肘部受伤的投手与未受伤的投手的数据进行比较。
总体而言，共纳入213名投手，其中53名（24.9%）在该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）。未发生肩部或肘部受伤的投手优势手臂平均握力为142.6±20.8磅（64.7±9.4千克），受伤的投手为148.2±20.9磅（67.2±9.5千克），两组握力无显著差异（P>0.05）。此外，两组在赛季期间握力的变化也无显著差异。
在一个赛季中，肩部或肘部受伤的职业棒球投手与未受伤的投手相比，平均握力及握力变化均无显著差异。
