Abstract

Context: Lumbopelvic control (LPC) and balance training programs are popular in the sport of basketball, but there is little research to indicate whether significant improvements in lumbopelvic control and balance are evident after completion of a training program. Objective: The objective of this study is to determine if conducting a six week lumbopelvic control and balance training program will lead to improvement in lumbopelvic control and balance in high school male basketball players. Design: This study will be a repeated measures design. Setting: High School in Western Pennsylvania. Patients and Other participants: This study includes 15 varsity and junior varsity basketball players. Fourteen players completed the study. The average age was 15.21+/-0.71 years old. Average height was 180.82+/-1.8cm, and average weight was 69.63+/-0.64kg. Inclusion criteria was healthy subjects who have not had shoulder, hip, or abdominal surgery within the year and have not had a shoulder, hip, or abdominal injury in the past six months. All participants were members of the boys' basketball team at the high school with a sport physical on file. Exclusion criteria will include those who have had shoulder, hip or abdominal surgery within the past year and those who have had a shoulder, hip or abdominal injury within the past six months. Interventions: The single leg raise test (SLRT) abdominal fatigue test (AFT), and the modified star excursion balance test (SEBT) were completed before and after performing a six week lumbopelvic and balance training program two times a week. The training program consisted of a progression of lumbopelvic and balance exercises based on level of difficulty and conducive to the sport of basketball. Main Outcome Measures: The dependent variables are the distances reached for both legs in three directions (anterior, posteromedial, and posterolateral) of the SEBT, degrees of anterior/posterior tilt of the pelvis in SLRT, and time held in AFT. Results: Significant differences were shown in the SLRT left leg (F1,13=7.556, P=0.017, ES= -0.80, 95% CI= -1.57 to -0.03). No significant differences were shown in the SLRT right leg, AFT, or SEBT in all directions. Large effect sizes were shown in AFT, all right leg SEBT directions, and SEBT left leg anterior direction. Moderate effect sizes were shown in SLRT right leg, SEBT posterolateral left leg, and SEBT posteromedial left leg. Conclusion: The six-week LPC and balance intervention program could be used to increase LPC, but do not show an ability to improve dynamic balance.
