Prior Injury, Health-Related Quality of Life, Disablement, and Physical Activity in Former Women's Soccer Players.

CONTEXT: Former collegiate athletes may be at risk for negative health outcomes such as lower health-related quality of life (HRQoL), greater disablement, and lower lifetime physical activity (PA) participation. A history of severe sport injury may play a role in these outcomes. OBJECTIVE: To assess the role of prior sport injury in self-reported HRQoL, levels of disablement, and PA behaviors of former National Collegiate Athletic Association Division I women's soccer players. DESIGN: Cross-sectional study. SETTING: Online survey. PATIENTS OR OTHER PARTICIPANTS: Former Division I women's soccer players (n = 382, age = 36.41 ± 7.76 years) provided demographics and injury history and completed the Patient-Reported Outcomes Measurement Information System (HRQoL), the Disablement in the Physically Active Scale (disablement), and the Godin Leisure Time Physical Activity Questionnaire (PA). MAIN OUTCOME MEASURE(S): The dependent variables were the physical and mental component summary scores for HRQoL and disablement and the frequency of moderate-to-vigorous PA. Means, SDs, and correlations among the main outcome variables were examined for those who reported a severe injury (n = 261) and those who did not (n = 121). To address our primary aim, we conducted multiple regression analyses to predict HRQoL, disablement, and PA based on a history of severe injury, accounting for age. RESULTS: Having a severe injury significantly predicted worse physical HRQoL and worse physical disablement. Severe injury predicted a >2-point decrease and 5-point increase on the respective scales. Injury status did not predict mental HRQoL, mental disablement, or PA. CONCLUSIONS: Most participants reported sustaining a prior severe soccer-related injury, which may have had a negative long-term effect on health outcomes for former women's soccer players. Athletic trainers should be aware of the risk for decreased HRQoL and increased disablement with injury and encourage continued monitoring of relevant patient-reported outcomes.

Substrate utilization during and after exercise in mild cystic fibrosis.

PURPOSE: To determine substrate utilization and energy expenditure during maximal and submaximal exercise and recovery in adolescents with cystic fibrosis (CF) and healthy age-matched controls (C). METHODS: Ten clinically stable CF patients (four girls, six boys; age = 10-22 yr) were matched by body mass index, age, gender, and Tanner stage to healthy controls. Subjects completed VO(2peak) testing and submaximal exercise (20 min) on a cycle ergometer at a relative intensity of 50% VO2(peak) and at an absolute power output (PO). Metabolic parameters were assessed during exercise and recovery (20 min). RESULTS: Similar respiratory quotient (RQ) values occurred in both groups during maximal exercise and recovery, despite differences in the maximal PO [CF = 114 (60-180) W and C = 171 (105-280) W, P = 0.006], the total work completed [CF = 27 (9.0-54.3) kJ and C = 55 (25.3-126.5) kJ, P = 0.008], or the VO(2peak) value attained [CF = 30.6 (8.5-45.2) mL kg(-1) min(-1) and C = 40.6 (29-64.5) mL kg(-1) min(-1), P = 0.027]. Submaximal exercise at the same absolute PO resulted in similar RQ values during exercise and recovery despite higher heart rates and average VO2 [CF = 18.8 (9.3-28.7) mL kg(-1) min(-1) and C = 15.2 (6.5-20.1) mL kg(-1)min(-1), P = 0.031] values in CF adolescents, and submaximal exercise at the same relative intensity also resulted in similar RQ values despite significantly greater average PO in the C group [CF = 38.7 (12.3-80) W and C = 67.8 (25.5-140) W, P = 0.039]. Excess postexercise oxygen consumption (EPOC) was greater in CF [2.79 (1.14-5.24) L O2] than C [1.46 (0.56-2.80) L O2] after submaximal exercise at a fixed PO (P = 0.036) but not after the relative exercise bout. CONCLUSIONS: Habitual physical activity participation does not warrant adjustment of macronutrient intake ratios in adolescents with mild to moderate CF, but total caloric intake may need to be increased based on the level of EPOC and upon the intensity and the duration of the habitual activity.
