Which intensities, types, and patterns of movement behaviors are most strongly associated with cardiometabolic risk factors among children?
ConclusionIn conclusion, greater than a dozen movement behavior characteristics were associated with cardiometabolic risk factors within both the most and least mature participants. Movement intensities within the moderate and vigorous intensity ranges were the most consistent correlates of these risk factors.Graphical abstract (Source: Journal of Sport and Health Science)

Impact of age on host responses to diet-induced obesity: Development of joint damage and metabolic set points
ConclusionThese findings indicate that the HFS Weanling group animals were better able to cope with the dietary challenge of an HFS diet than the HFS Adult group animals. Interestingly, when assessing various serum pro-inflammatory markers, no significant differences were detected between the HFS Adult and HFS Weanling groups. Although details regarding the mechanisms underlying an increase in knee joint damage scores in the HFS Adult group remain to be elucidated, these findings indicate that dietary exposure time maybe less important than the age at which a HFS diet is introduced. Moreover, increases in serum pro-inflamm...

Age-related changes in proprioception of the ankle complex across the lifespan
Conclusion: The test method of AMEDA is sensitive to age differences in ankle complex proprioception. For proprioception of the ankle complex, young adults had significantly better scores than children, adolescents, old adults, and very old adults. The middle-aged group had similar level of ankle proprioceptive acuity to the young adults. The scores for males and females were not significantly different. Examination of the range of the scores in each age group highlights the possible level that ankle complex movement proprioceptive rehabilitation can reach, especially for those 75–90 years of age.Graphical Abstract (Sour...

Motivational processes in physical education and objectively measured physical activity among adolescents
ConclusionThe findings of the current study support the applicability of the SDT-based model in explaining the antecedents of objectively measured MVPA of adolescents. In order to enhance adolescents’ daily MVPA, special focus should be put on increasing their intrinsic motivation towards physical education.Graphical abstract (Source: Journal of Sport and Health Science)

Effect of high-intensity interval training in adolescents with asthma: the eXercise for Asthma with Commando Joe's® (X4ACJ) trial
Conclusions: HIIT represents an effective tool for improving aerobic fitness and maintaining BMI in adolescents, irrespective of asthma status. HIIT was well tolerated by those with asthma, who evidenced a similar aerobic fitness to their healthy peers and responded equally well to a HIIT programme.Graphical abstract (Source: Journal of Sport and Health Science)

Enhanced inhibitory control during re-engagement processing in badminton athletes: An event-related potential study
ConclusionModeration of brain cortical activity in badminton athletes was more associated with their ability to rapidly inhibit a planned movement and reengage with a new movement compared with nonathletes. The superior inhibitory control and more efficient neural mechanisms in badminton athletes compared with nonathletes might be a result of badminton athletes’ professional training experience.Graphical abstract (Source: Journal of Sport and Health Science)

Correlation Network Analysis Shows Divergent Effects of a Long-Term, High-Fat Diet and Exercise on Early-Stage Osteoarthritis Phenotypes in Mice
ConclusionDespite minimal group-level effects of chronic diet-induced obesity and voluntary wheel running on knee OA pathology under the current test durations, diet and exercise substantially altered the relationships among systemic and local variables associated with early-stage knee OA. These results suggest that distinct pre-OA phenotypes may exist prior to the development of disease.Graphical Abstract (Source: Journal of Sport and Health Science)

Implementing physically active learning: Future directions for research, policy, and practice
ConclusionThe present study is the first to identify PAL implementation factors using a combined multi-stakeholder perspective. To achieve wider PAL adoption and implementation, future interventions should be evidence-based and address implementation factors at the classroom level (e.g., approaches and delivery environments), school level (e.g., communities of practice) and policy level (e.g., initial teacher training).Graphical Abstract (Source: Journal of Sport and Health Science)

The potential of a year-round school calendar for maintaining children's weight status and fitness: Preliminary outcomes from a natural experiment
ConclusionThe year-round school calendar had a small beneficial impact on children's weight status but not CRF. It is unclear if this benefit to children's weight would be maintained because gains made in the summer were largely erased during the school year. Trajectories of weight and CRF gain/loss were consistent with the structured days hypothesis.Graphical Abstract (Source: Journal of Sport and Health Science)

Effects of obesity on breast size, thoracic spine structure and function, upper torso musculoskeletal pain and physical activity in women
ConclusionThis study is the first to demonstrate that increased obesity levels were associated with compromised kyphosis and loading of the thoracic spine, as well as increased symptoms of upper torso musculoskeletal pain and reduced time spent in physical activity in women living in the community. We recommend further research to determine whether evidence-based interventions designed to reduce the flexion torque generated on the thoracic spine can improve these symptoms of upper torso musculoskeletal pain and the ability of women with obesity to participate in physical activity.

Modeling the dose-response rate/associations between VO2max and self-reported physical activity questionnaire in children and adolescents
ConclusionHealth practitioners should be aware that encouraging greater PA (same dose) in inactive and underweight children will result in greater gains in VO2max (response) compared with their active and overweight/obese counterparts.Graphical abstract (Source: Journal of Sport and Health Science)
