The purpose of this study was to investigate if lumbopelvic-hip control was correlated with shoulder and elbow joint moments and drive leg ground reaction force (GRF) in high school baseball pitchers. The hypothesis was that poorer lumbopelvic-hip control would be correlated with higher joint moments and lower drive leg GRF.<\/jats:p>\n                    <jats:p>Study design: Cross-sectional study.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"methods\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Lumbopelvic-hip control was assessed based on the anterior-posterior pelvis angular displacement using the single-leg lift test (SLLT) on each limb. Peak shoulder horizontal adduction and internal rotation and elbow varus moments during pitching were calculated using inverse dynamics. The correlations between lumbopelvic-hip control and the biomechanical variables (i.e., normalized joint moments, peak anterior GRF, and anterior GRF impulse) were analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"results\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Sixty healthy high school pitchers (age: 15.8 \u00b1 1.3) recruited from local baseball training facilities participated. The lumbopelvic-hip control while standing on the drive leg had a moderate correlation with the peak shoulder horizontal adduction moment during pitching (r=.301, p=0.02) but not with peak shoulder internal rotation moment (p=0.19), elbow varus moment (p=0.95), peak anterior GRF (p=0.95), or anterior GRF impulse during the drive (p=0.61). Lumbopelvic-hip control while standing on the lead leg was not correlated with any variables.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"conclusions\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Poorer lumbopelvic-hip control was moderately correlated with greater shoulder horizontal adduction moment during throwing among high school baseball pitchers.
