Many runners prefer to listen to music. Removing music may impact exercise performance and possibly gait retraining adherence. Increased step-rate accuracy and adherence were compared between music and metronome in-field gait retraining. Thirty healthy individuals were allocated to groups (music or metronome) then completed a pretest running assessment while step-rate was collected. Target step-rate was calculated (+5% above preferred). After five in-lab, guided gait retraining sessions, participants were told to continue practicing on their own for approximately 1-month while step-rate and running mileage were monitored remotely via an app. Participants returned for a posttest to collect step-rate and were categorized as adherent or nonadherent based on their monthly activity. A 2 × 2repeated measures ANOVA was performed to determine differences in step-rate (group by time). A Fisher's exact test and odds ratio examined the relationship between group and adherence. The music and metronome groups increased step-rate (<i>p</i> < .001) from pretest to posttest. A significant association between group and adherence was found (<i>p</i> = .045).

Moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), sedentary behavior, and sleep were assessed using accelerometers in combination with a questionnaire. Physical fitness was tested through body mass index, forced vital capacity, 50-m sprint, standing long jump, sit-and-reach, gender-specific 800/1000-m run, and pull-ups/sit-ups. MVPA was significantly associated with better performance in the 50-m sprint (<i>β</i> = -0.29, 95% <i>CI</i> = -0.47 to -0.11) and the standing long jump (<i>β</i> = 14.50, 95% <i>CI</i> = 8.07 to 20.93), while LPA was significantly associated with sit-and-reach (<i>β</i> = 5.23, 95% <i>CI</i> = 2.11 to 8.35).

To manage these demands, practitioners track training load, travel variables and athlete-reported outcome measures (AROMs), which reflect subjective perceptions of fatigue, sleep and soreness. Despite their widespread use in professional sports, no prior studies have assessed how these factors jointly influence player well-being and performance across an NBA season. This study examined the impact of on-court training load and travel demands on AROM responses and individual in-game performance among 14 NBA players. Data included training load, travel-related variables (elevation, time zone changes, nights away), AROMs and game performance metrics. Multi-level modelling (MLM) assessed relationships between 5- and 10-day cumulative loads, travel demands and performance outcomes. Results showed that defensive performance varied significantly with elevation (p = 0.005), time zone acclimation (p = 0.055) and 5-day load (p = 0.065). Time zone acclimation also negatively influenced mood, though other AROMs (fatigue, soreness, sleep and stress) were unaffected.
