Using bike share could increase physical activity and improve health. This study used the social-ecological model to identify predictors of frequent bike share trips for different purposes. Participants residing in the U.S. were recruited via Amazon Mechanical Turk (MTurk). Self-report trip purposes were used to group participants into using bike share for commuting only (n = 260), social/entertainment only (n = 313), exercise only (n = 358), dual or triple-purpose (n = 501), and purposes other than commuting, social/entertainment, and exercise (n = 279). Results showed that at the intrapersonal level, perceived use of bike share to be helpful for increasing physical activity was a significant predictor for all groups, except for the other purpose group. Adjusting outdoor activity based on air quality was a significant predictor for the dual or triple-purpose group. At the interpersonal level, having four or more friends/family using bike share was a significant predictor for the other purpose group. At the community level, distance to the nearest bike share within acceptable range was a significant predictor for social/entertainment and dual or triple-purpose groups. The findings suggest that it is important to consider factors at multiple levels for predicting bike share usage. Moreover, health educators and policy makers should adopt different strategies for promoting bike share usage based on trip purposes.

Purpose: This pilot study aimed to determine the feasibility of hip corrective taping to improve self-reported knee pain and lower extremity joint kinematics in basketball players with patellofemoral pain. Patients and Methods: A single group pre-test and post-test design. Collegiate basketball players with patellofemoral pain were recruited. Three-dimensional hip and knee joint kinematics were measured during two tasks, single-leg squat (SLS) and lay-up jump (LUJ), and each task was conducted under no-taping and taping conditions. Subjective report of pain was compared between no-taping and taping conditions only during SLS. Results: Twelve collegiate basketball players with patellofemoral pain (median age, 22.7 [2.5] years; mean height, 173.8 ± 7.4 cm; mean weight, 72.5 ± 12.8 kg) participated in this study. Compared with no-taping, the use of hip corrective taping significantly increased the hip abduction angle at the instant of the maximal vertical ground reaction force during LUJ (no-taping vs taping: 0.6° ± 6.3° vs 3.3° ± 5.1°, p = 0.029), and also caused a trend of decreased maximal hip internal rotation angle during SLS (no-taping vs taping: 8.0° ± 6.6° vs 4.7° ± 6.9°, p = 0.050). Hip corrective taping also improved self-reported knee pain during SLS (no-taping vs taping: 3.4 ± 1.7 vs 2.6 ± 1.0, p = 0.046). Conclusion: Hip corrective taping may be used as an effective intervention for athletes with patellofemoral pain during basketball-related tasks.

While most studies have focused on investigating the preventive effects of physical activity on metabolic risk, the longitudinal impacts of metabolic syndrome (MetS) on activity levels is poorly understood. This study aims to examine the influence of MetS on initial activity levels and the trajectory of activity levels in Latina and African American female children over 12 months (n = 55, 9 ± 1 years). Metabolic measures, including fat and lean tissue mass by BodPod, fasting glucose, lipids, blood pressure, and waist circumference, were collected at baseline. Moderate-to-vigorous physical activity and sedentary behavior by accelerometry were collected on a quarterly basis. There were no significant differences in either initial activity levels by MetS status (Moderate-to-vigorous physical activity: 33 ± 12 mins/day for MetS, 48 ± 28 mins/day for Non-MetS, p = .12; sedentary behavior: 408 ± 57 mins/day for MetS, 421 ± 72 mins/day for Non-MetS, p = .67). Longitudinal declines in moderate-to-vigorous physical activity (p = .038) and increases in sedentary behavior (p = .003) were found. Daily sedentary behavior increased by 82.64 more minutes in youth with MetS than in those without over one year (p = .015). This study yields the first evidence of the adverse effect of MetS on sedentary behavior. Targeted intervention strategies to reduce progressive sedentariness evident in minority youth with MetS are warranted.
