Adherence to exercise rehabilitation has been shown to be an important factor that may influence successful treatment. In professional athletes, a significant reduction in exercise adherence delays recovery. The aim of this study was to explore barriers to and facilitators of exercise rehabilitation adherence in injured volleyball athletes. Eight professional volleyball athletes were recruited, and qualitative data were collected using semistructured interviews. All athletes had completed their rehabilitation program after they had suffered a musculoskeletal injury. All data were analyzed using thematic analysis after the investigators ensured that saturation had been reached. Pain was identified as a significant barrier to exercise adherence by all athletes. The provision of social support, including mental, practical, and task related, also had a significant positive impact. The athletes’ ability to develop the necessary coping strategies and confidence on performing exercises at home was also mentioned as a factor that affected exercise adherence, although less often.

The U.S. Report Card on Physical Activity for Children and Youth has tracked 10 physical activity (PA) indicators common to the Active Healthy Kids Global Matrix since 2014. This article expands on the U.S. report cards by presenting PA indicator assessments among children and adolescents with disabilities. Grades for indicators were assigned based on a search of peer-reviewed articles presenting nationally representative data. The Global Matrix 3.0 benchmarks and grading framework guided the process. Grades for overall PA, sedentary behaviors, organized sports, and school were F, D+, D+, and D, respectively. Insufficient evidence existed to assign grades to the remaining six indicators. There is a need in the United States for targeted PA promotion strategies that are specific to children and adolescents with disabilities. Without a commitment to this effort across sectors and settings, the low grades identified in this para report card are expected to remain.

Left–right differential erector spinae (ES) muscle strengthening is required to correct ES muscle imbalances. The objective was to test the effect of 6 body positions on the differential activation of the ES muscles. In 14 able-bodied young women, using a surface electromyography system, the bilateral ES muscles activity at the third lumbar (ESL3) and the 10th (EST10) and 6th (EST6) thoracic vertebral levels was measured with the contralateral arm and leg lifted in the prone and quadruped conditions and with a single arm lifted in the quadruped position. Results showed that the activity of the ESL3 was symmetrical (P > .05) and significantly smaller than that of the thoracic ES muscles in all body positions (P < .01). The EST10 and EST6 were differentially activated in all tests (P < .001). Besides, the differential activation was higher in the contralateral-arm and -leg lift in the quadruped position than in the other positions. In conclusion, contralateral-arm and -leg lift and single-arm lift in the quadruped and prone positions are capable of differentially activating the ES muscles on one side more than the other side. Further studies are recommended to examine the effectiveness of these exercises on the correction of ES muscle imbalances in clinical populations.

This study assessed the effectiveness of a passive back support exoskeleton during a mechanical loading task. Fifteen healthy participants performed a simulated patient transfer task while wearing the Laevo (version 2.5) passive back support exoskeleton. Collected metrics encompassed L5-S1 joint moments, back and abdominal muscle activity, lower body and back kinematics, center of mass displacement, and movement smoothness. A statistical parametric mapping analysis approach was used to overcome limitations from discretization of continuous data. The exoskeleton reduced L5-S1 joint moments during trunk flexion, but wearing the device restricted L5-S1 joint flexion when flexing the trunk as well as hip and knee extension, preventing participants from standing fully upright. Moreover, wearing the device limited center of mass motion in the caudal direction and increased its motion in the anterior direction. Therefore, wearing the exoskeleton partly reduced lower back moments during the lowering phase of the patient transfer task, but there were some undesired effects such as altered joint kinematics and center of mass displacement. Statistical parametric mapping analysis was useful in determining the benefits and hindrances produced by wearing the exoskeleton while performing the simulated patient transfer task and should be utilized in further studies to inform design and appropriate usage.

Evaluating athletes’ knowledge of and attitudes toward sports-related concussions is important. However, there is limited research involving South Asian athletes, partly due to the lack of a valid and reliable tool. This study, therefore, aimed to translate and validate the Rosenbaum Concussion Knowledge and Attitude Survey—Student Version, an established tool used to measure knowledge and attitude toward concussion, into Urdu. Rosenbaum Concussion Knowledge and Attitude Survey—Student Version was translated into Urdu using the standard guidelines and then completed by 369 athletes participating in contact sports at different universities in Pakistan. Confirmatory factor analysis was performed on the Concussion Attitude Index items to examine the underlying factorial structure. Construct validity of Concussion Attitude Index factors was also investigated using convergent and discriminant validity. The results showed that the Urdu version of the Rosenbaum Concussion Knowledge and Attitude Survey—Student Version has good psychometric properties and is a valid and reliable tool for evaluating Urdu-speaking athletes’ knowledge of and attitudes toward concussions.

The purpose of this study was to provide new knowledge about the temporal and contextual aspects of the alcohol–sport relationship. Eight U.K. student-athletes completed the Alcohol Use Disorders Identification Test in their final year at university, 18 months, and 30 months after graduation. They also completed semistructured interviews about their drinking motives, behaviors, and life circumstances. Results showed that participants reduced their alcohol consumption after leaving university, but despite the onset of some adult responsibilities, most were still drinking at hazardous levels. After university, drinking took place with old friends, new colleagues, and new sporting teammates. At all time points, social drinking motives were the most prevalent. Findings demonstrate a relationship between alcohol and sport that is cemented at university but continues beyond it. Targeted interventions to reduce the role of alcohol in the social experience of sport are needed to support long-term athlete health.
