Summary: The purpose of this study was to determine the criterion validity of the ACT24 recall tool for estimating sedentary versus active time and time spent in activity domains. The results showed that ACT24 is accurate for group-level estimation of sedentary and active time. The domain-specific agreement tends to be higher for more commonly reported and longer duration activities.

Summary: The study revealed that leisure sedentary time of 8+ hours per day is associated with an increased risk of stroke, especially among individuals under 60 years of age with low physical activity levels. This highlights the importance of promoting physical activity and reducing sedentary behavior in younger individuals.

Summary: The daily combination of activities has a significant impact on fitness and adiposity in children, with differing optimal time durations for each outcome. Balancing both fitness and adiposity, the overall optimal time-use composition includes approximately 10.2 hours of sleep, 9.9 hours of sedentary time, 2.4 hours of light physical activity, and 1.5 hours of moderate-to-vigorous physical activity.

Summary: The study utilized machine learning to develop race-specific heart failure risk prediction models and identified natriuretic peptide levels as the most important predictor of heart failure risk across races. Additionally, troponin levels in Black individuals and ECG-based Cornell voltage in White individuals were significant predictors of heart failure risk. There were distinct differences in heart failure risk factors between different races.

Summary: Sedentary time is associated with higher mortality risk in individuals accumulating less than 22 min of MVPA per day. Higher levels of MVPA are associated with lower mortality risk regardless of the amount of sedentary time.

Summary: According to the results of this study, community dwelling adults who were highly physically active and performed frequent sedentary breaks were less likely to have high blood pressure during a 2-year follow-up. Therefore, strategies for controlling high blood pressure should consider both physical activities and leisure sedentary breaks in the adult population.

Summary: Promoting physically active travel is important for population health. We used travel survey data from 41,628 Australian adults to investigate the influence of sociodemographic and environmental attributes on active and sedentary travel durations. Decision tree modeling helped identify at-risk subgroups and inform policy interventions.

Summary: This study examined the relationship between move-ment behavior composition and polysubstance use among grade 6-10 students. Results showed that sleep was negatively associated and screen time was positively associated with polysubstance use. Reallocating physical activity or screen time into sleep was associated with lower polysubstance use, except for boys in grades 9-10 where reallocating physical activity into screen time or sleep was associated with greater polysubstance use.

Summary: This study aimed to assess and compare sedentary time (ST) of university students before and during the COVID-19 pandemic. The results showed that even during a global pandemic lockdown, individuals who were previously more physically active and had less sedentary time showed more health-promoting behavior in terms of ST. Efforts to promote physical activity and reduce sedentary behavior are always valuable. Since sedentary time increased and was worryingly high in all subgroups analyzed, multidimensional approaches should be targeted to tackle sedentary behavior and promote the health of university students.

Summary: This study aimed to investigate the impact of screen time on health and academic performance on school days and non-school days, and identified different screen time profiles using cluster analysis. The results showed that adolescents with higher screen time had poorer health behaviors and academic performance, while those with lower screen time showed the opposite pattern.

Summary: This study examines the views of professionals from different disciplines involved in delivering walking environments in Auckland, New Zealand. The results indicate a consensus on the complexity associated with providing quality walking environments in a car-dominated city, as well as the importance of the quality of street environments. The study highlights the need for higher interdisciplinary collaboration, reviewed delivery processes, and better-quality data in urban retrofit efforts.

Summary: The study found that machine learning models achieved good accuracy in measuring bowling volume, ball release speed, and perceived intensity zone for fast bowlers. Placing the IMU on the dominant wrist improved the classification accuracy of PIZ, but there was no additional benefit of combining IMUs on the dominant and non-dominant wrists for all measures.

Summary: The study compared the accuracy of different devices in measuring human movement location, showing strengths and weaknesses in different environments. Holux was more accurate in parks and housing estates, while Garmin performed better in city centers. The location accuracy of Holux and Garmin was found to be comparable to that of Qstarz, making them suitable instruments for locating physical activity.

Summary: AMPK, a cellular energy sensor, plays a key role in metabolic adaptations to endurance training and its activation during exercise is influenced by factors such as exercise intensity, muscle glycogen, and fitness level. The study found that disrupting cellular energy charge is the most influential factor for AMPK activation during endurance exercise.

Summary: This study investigates the factors influencing respiratory exchange ratio (RER) during continuous exercise. It identifies exercise duration, dietary intake, and sex as the most influential factors on RER. The study also suggests that current models cannot fully explain the variability in RER and calls for further research on older subjects, females, and other factors that could explain additional variability.

Summary: The aim of this research was to examine the relationship between perceived organisational support, motivation, and intention to continue in referees. The study found differences in motivation between early-career referees and seasoned referees, and perceived organisational support was found to moderate sport-related motivation. Furthermore, the results suggest that the effects of motivation, perceived organisational support, and intention to continue vary across different groups of referees.

Summary: Differences in workload exist between netball playing positions and competition levels, and this study compares the workloads of elite players during national and international competitions. The results show that internal workload is greater in national competitions, while PlayerLoad is greater in international competitions. There are also positional differences in workloads between the two competitions. Additionally, workloads are generally higher when playing against higher-ranked international opponents.

Summary: The purpose of this study was to investigate whether there is nonergodicity in the relationship between daily carbohydrate intake and perceived recovery status. The results showed that carbohydrate intake did not influence recovery status for most individuals, but the influence of dietary carbohydrate intake on daily recovery differed at the group and individual level. Therefore, practical recommendations should be based on individual-level analysis.
