Exclusion criteria included pain during throwing, history of surgery, or upper\u2010extremity injuries within 12 months. Catchers performed 5 throws for each of the following throwing conditions: squatting throwing, standing throwing, and maximum effort throwing. Catchers were outfitted with a wearable sensor sleeve that recorded the medial elbow torque, arm speed, and shoulder rotation. Ball velocity was measured using a radar gun.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Final analysis included 42 catchers (mean age, 11.5 \u00b1 1.2 years; mean catcher experience, 16.7 \u00b1 10.3 months). The medial elbow torque was significantly greater during maximum effort throwing (19.0 \u00b1 5.2 Nm) than during squatting throwing (14.3 \u00b1 5.4 Nm) and standing throwing (15.7 \u00b1 4.7 Nm) (both\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001); there was no significant difference between squatting throwing and standing throwing. Multiple linear regression analysis showed that the ball velocity was significantly positively associated with the medial elbow torque during squatting throwing and standing throwing (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .023 and\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .029, respectively).

Increased medial elbow torque was associated with greater ball velocity during squatting throwing and standing throwing and with decreasing hip joint IR ROM on the throwing side during squatting throwing. Evaluation and stretching of the hip joint IR ROM on the throwing side may be important to decrease elbow stress during squatting throwing in youth baseball catchers.<\/jats:p>\n
