Background: In 2011, physical inactivity was described as the Cinderella risk factor for noncommunicable diseases. This metaphor was used to highlight the disjunct between the advancing evidence on physical inactivity as a risk factor for ill health, its high prevalence, and the paucity of global policy response or priority afforded to physical activity. This paper describes the strategic actions of the International Society for Physical Activity and Health (ISPAH) to raise the profile of physical activity as a global public health priority. Methods: From 2008, ISPAH coordinated a long-term advocacy strategy to advance the status of physical activity and promote its presence as a priority within global health policy. The society employed an advocacy mix that reflected contemporary advocacy theory and models. Results: Through 6 advocacy deliverables, aligned to the global calendar of United Nations and World Health Organization policy developments, ISPAH seized the opportunity to advance physical activity policy and strategies to inform global noncommunicable disease action planning and align with the Sustainable Development Goals. ISPAH’s successful execution of global advocacy for physical activity highlights the importance of leadership, clear objectives, progressive action, timeliness, partnerships, and persistence. Conclusion: As a result of strategic global advocacy since 2008, the field in 2024 is better positioned in relation to global professional mobilization, policy, and technical support for physical activity. However, despite impressive progress across more than 12 years, and the innovation of the Global Action Plan on Physical Activity, the work of global advocacy for physical activity is far from complete.

The Current Status of Leisure Constraints, Leisure Sports Behaviors, and Active Aging Among Chinese Older Adults
Yajun Qiu, Yi Shang, Haibo Tian, and Dongjun Yang
Background: Against the backdrop of China’s active response to population aging, an increasing number of older adults are participating in leisure sports activities to enrich later life and experience active aging. However, when participating in these activities, older adults encounter constraints that affect their leisure sports behaviors. Methods: To understand the current state of leisure constraints, leisure sports behaviors, and active aging among Chinese seniors, we collected 1,581 surveys from older adults in Zhejiang Province, China. A stepwise regression model was used to explore the relationships between leisure constraints and leisure sports behavior as well as between leisure sports behavior and active aging. Results: The respondents’ leisure sports were characterized by light-intensity, moderate duration, high-frequency, and long-term participation with various leisure constraints, such as a lack of organized leisure sports activities. However, the respondents reported that their aging status was positive. Leisure constraints were negatively associated with leisure sports behavior, and self-constraint had a significant impact on leisure sports behavior. Leisure sports behavior positively affected the active aging of older participants and was positively associated with the four subdimensions of active aging: health, participation, security, and lifelong learning. Conclusion: High-frequency and long-term participation in leisure sports is an effective strategy for Chinese seniors to promote active aging. However, there are still many constraints that limit the leisure sports behaviors of older adults. Implications: The findings may inspire Chinese older adults to achieve active aging through leisure sports and provide support for the literature.

This study investigated the effect of oral and topical sodium bicarbonate (SB) on soccer-specific performance during simulated soccer exercise. In a block randomized, double-blind, crossover design, 10 collegiate male soccer players (stature: 181.7 ± 3.2 cm, body mass: 81.7 ± 10.5 kg) performed soccer-specific performance tests (countermovement jumps, Illinois agility, 8 × 25 m repeated sprints) throughout a 90-min soccer-specific aerobic field test (SAFT90) following 0.3 g/kg body mass SB in capsules (SB-ORAL), 0.9036 g/kg body mass PR Lotion (SB-LOTION), or placebo capsules and lotion (PLA). Soccer-specific performance tests were conducted pre-SAFT90, during half-time and post-SAFT90. Blood samples were analyzed for acid–base balance (pH; bicarbonate,
Validation of Linear and Nonlinear Gait Variability Measures Derived From a Smartphone System Compared to a Gold-Standard Footswitch System During Overground Walking
Vincenzo E. Di Bacco and William H. Gage
Smartphones, with embedded accelerometers, may be a viable method to monitor gait variability in the free-living environment. However, measurements estimated using smartphones must first be compared to known quantities to ensure validity. This study assessed the validity and reliability of smartphone-derived gait measures compared to a gold-standard footswitch system during overground walking. Seventeen adults completed three 8-minute overground walking trials during 3 separate visits. The stride time series was calculated as the time difference between consecutive right heel contact events within the footswitch and smartphone-accelerometry signals. Linear (average stride time, stride time standard deviation, and stride time coefficient of variation) and nonlinear (fractal scaling index, approximate entropy, and sample entropy) measures were calculated for each stride time series. Bland–Altman plots with 95% limits of agreement assessed agreement between systems. Intraclass correlation coefficients assessed reliability across visits. Bland–Altman plots revealed acceptable limits of agreement for all measures. Intraclass correlation coefficients revealed good-to-excellent reliability for both systems, except for fractal scaling index, which was moderate. The smartphone system is a valid method and performs similarly to gold-standard research equipment. These findings suggest the development and implementation of an inexpensive, easy-to-use, and ubiquitous telehealth instrument that may replace traditional laboratory equipment for use in the free-living environment.

Concussion History Moderates Trunk Motion and Lower Extremity Biomechanical Relationships During Jump Landing and Cutting
Kayla M. Kowalczyk, Eric J. Shumski, Julianne D. Schmidt, and Robert C. Lynall
Concussion history, trunk motion, and lower extremity biomechanics associate with musculoskeletal injury risk. We aimed to examine the interaction between concussion history and trunk motion as possible modifiable factors for injury risk biomechanics during jump landing and cutting. Division I female athletes (24 with, 20 without concussion history) performed jump landings and jump-to-cuts at 45° in the opposite direction of the landing limb. We used multiple linear regressions with interaction terms to examine ankle dorsiflexion angle, knee flexion and abduction angle, and external knee flexion and abduction moment. We observed a group by trunk flexion interaction for nondominant external knee flexion moment (P = .042) during jump landing. Concussion history associated with increased external knee flexion moment as trunk flexion increased. We observed a group by trunk flexion interaction for the dominant limb dorsiflexion angle (P = .044), and group by trunk lateral bending interactions for the dominant (P = .039) and nondominant limb (P = .016) external knee flexion moment during cutting. During cutting, concussion history associated with decreased dominant dorsiflexion angles as trunk flexion increased, and decreased dominant and nondominant external knee flexion moment as lateral bending toward the planted limb increased. Concussion history associated with atypical biomechanics as trunk flexion and lateral bending increased.
Menthol Mouth Rinsing Improves Cycling Performance in Trained Adolescent Males Under Heat Stress
Kierstyn V. Hawke, Erica H. Gavel, David J. Bentley, and Heather M. Logan-Sprenger
Purpose: This study investigated the effect of menthol (MEN) mouth rinsing (MR) on cycling performance during a modified variable cycle test (M-VCT) in adolescent athletes under hot conditions (31.4 ± 0.9 °C, 23.4 ± 3.7% relative humidity). Methods: Trained adolescent male cyclists (n = 11, 16.7 ± 1.3 years, height 176.6 ± 8.8 cm, body mass 65.8 ± 11.6 kg, maximal oxygen uptake 62.97 ± 7.47 ml·kg−1·min−1) voluntarily completed three trials (familiarization and two experimental) of a 30-min M-VCT, which included five 6-min laps consisting of three 6-s accelerations and three 10-s sprints throughout each lap. In a randomized crossover design, MEN (0.01%) or placebo (PLA) (crystal-light), was swilled for 5 s before the start of each lap (total of 6 MR). Power output, distance (in kilometers), core temperature, heart rate, perceptual exertion, thermal stimulation (thermal comfort and thermal sensation), and blood lactate concentration were recorded. Results: MEN MR significantly improved M-VCT mean power output by 1.81 ± 1.57% compared to PLA (MEN, 177.8 ± 31.4 W; PLA, 174.7 ± 30.5 W, p < .001, 95% confidence interval [1.73, 4.46], d = 1.53). For maximal intermittent sprints, 6- and 10-s mean power output was significantly higher with MEN than PLA (6 s, p = .041, 95% confidence interval [0.73, 27.19], d = 0.71; 10 s, p = .002, 95% confidence interval [11.08, 35.22], d = 1.29). There was no significant difference in core temperature, heart rate, blood lactate concentration, or any perceptual measure between trials (p > .05) despite significantly higher work with MEN. Conclusion: 64% of athletes (7/11) improved M-VCT performance with MEN. The results of this investigation suggest that a MEN MR may improve power output during a sport-specific stochastic cycling task in elite adolescent male cyclists.
