“…There were several potential limitations to the study that may have influenced the type and number of injuries reported. These included the inability to determine and control the inherent random variation in injury typically observed in high-collision team sports 8, 38 ; the strength and conditioning status of the athletes and variations in the type of equipment used 2, 17, 29, 30, 35, 64 ; weather conditions and variations in field conditions 2 ; differences in postural/joint integrity, musculoskeletal structure, and biomechanics of movement 9, 28, 70, 72 ; coaching style and play calling 2, 7, 24, 35 ; quality of officiating and foul play 71 ; player position and actual versus average time of exposure to injury 25, 29, 33 ; sport skill level, intensity of play, and fatigue level at time of injury 9, 23, 33, 36, 64, 70, 71 ; an athlete's ephemeral response to help seeking, injury, and subsequent pain 1, 9, 11, 35, 40, 52 ; player eligibility 2 ; unreported congenital/developmental factors predisposing an athlete to additional injury 9, 30, 35, 71, 77 ; or simply unforeseen mishap. 28, 38 Also, there is always the opportunity for an injury to go unreported despite the comprehensive nature of any reporting system, 35 and although our study revealed significant and unique differences in injury causes, generalizability of the findings across the country may not be warranted because of varying environmental, field, and injury management conditions.…”
