Abstract Exercise is known to induce several neural and muscular adaptations, such as increased muscle mass functional capacity in older adults. In this study, we investigated its impact on the neuromuscular control of gait among young adults, divided into two groups: more active (young: n=15; 5185 ± 1471 MET-min/week; old: n=14; 6481 4846 MET-min/week) less participants 1265 965 1473 859 MET-min/week). Maximal isometric tests ankle knee extension revealed a reduction force with differences associated level physical activity at level. Gait mechanics no significant between adults contrast, exhibited shorter steps, higher mechanical cost, greater collision heel strike. These changes cannot be attributed solely reductions strength. Instead, they are likely result modifications properties muscles Specifically, wider activation (and coactivation) lumbar sacral motor pools well different timing were observed. Also, their muscle-tendon stiffness was reduced. conclusion, our findings highlight that age-related decline efficiency exacerbated by sedentary lifestyle. Even modest increases appear preserve improve walking performance. This suggests interventions aiming enhance levels could mitigate declines mechanics.

Dance is a promising health resource for older adults, but empirical evidence remains inconsistent. The lack of synthesised regarding program design, dose, and delivery limits understanding factors influencing participation outcomes. This scoping review aimed to map the scope, range, effectiveness dance programs people, identify gaps opportunities future research practice. Searches across five databases (September 2023) identified 148 studies evaluating 116 (≥4 weeks) adults (≥55 years, N = 8060), interventions delivered clinical groups were excluded. Intervention design charted against TIDieR reporting checklist. Program outcomes including adherence, safety, positive tests into established taxonomies. Demographic information, details, implementation often insufficiently reported. Participant differed by age with underserved communities underrepresented. Programs varied extensively in key prospective 'active ingredients', approach, facilitator expertise, class size. While was physically safe, adherence rates are comparable other community exercise programs. Less than 40% assessments showed change, more consistent benefits physical endurance, strength, function, moderate impacts on psychosocial health, limited cognitive brain falls risk. meaningful, adaptable, low-cost adults. Key advancing include improved access groups, suitability assessments, strategies support engagement theory-informed approaches, incorporation participant practitioner insights. Identification ingredients' may improve causal pathways mechanisms optimise impacts. Stronger practices will facilitate comparisons robust synthesis. provides critical knowledge foundation guide approaches offers recommendations.

Anterior cruciate ligament (ACL) injuries are prevalent and movement patterns linked to an increased risk of ACL damage can be seen in youngsters under the age 10. Though processes underlying these programs mostly unclear, prevention systems have been demonstrated lower rates injury. Biomechanical alterations following injury children not extensively studied. In this study, we examine manner which modifications bio-mechanical variables for preadolescent female soccer players affected by F-MARC 11+ injury-preventing warm-up program. Our hypothesis was that training would enhance peak knee valgus moment (PKVM), key factor injuries. Other kinematic kinetic factors connected were also investigated. An intervention group a control created from total 62 athletes who recruited teams. in-season sessions attended fifteen times. Motion capture information pre post-season gathered while doing activities such as double-leg leap, single-leg jump, unanticipated cutting preplanned cutting. A biomechanical modeling system called OpenSim used determine angles moments extremity joints. According results experiment, during got had PKVM than those group. This study suggests ways improve programs, especially jobs, reduce other factors.

Abstract Background Ageing populations experience greater risks associated with health and survival. It increases the relevance of identifying variables mortality. Grip strength (GS) has been identified as an important biomarker for all cause cardiovascular mortality, however, its prognostic value not studied in Lithuania. The aim present study is to evaluate relationship GS vital status a representative sample Lithuanian 45–72-year-old urban population during period 12 years follow-up explore associations all-cause mortality from diseases (CVD). Methods Within framework international Health, Alcohol Psychosocial Factors Eastern Europe (HAPIEE) 7,115 men women 45–72 age were examined baseline survey (2006 2008).
