AOP was consistently associated with greater PA, especially moderate-to-vigorous PA; meta-analysis showed a moderate positive correlation with high heterogeneity (r = 0.60, 95% confidence interval (95%CI): 0.34-0.78, p = 0.0004; I² = 99.2%). AOP was also linked to less sedentary behavior: children were sedentary 38% of the time outdoors vs. 67% indoors. Meta-analyses showed a small, significant negative correlation with sedentary time (r = -0.05, 95%CI: -0.07 to -0.02, p < 0.0043; I² = 7.0%) and a small, non-significant correlation with screen time (r = -0.19, 95%CI: -0.38 to 0.02, p = 0.0638; I² = 98.9%).

{"title":"The influence of body posture and added mass on intrinsic and extrinsic foot muscle activation and force output during common foot strengthening exercises.","authors":"John W A Osborne,Hylton B Menz,Karl B Landorf,Glen A Whittaker,Matthew Cotchett,Luke A Kelly","doi":"10.1016/j.jshs.2025.101110","DOIUrl":"https://doi.org/10.1016/j.jshs.2025.101110","url":null,"abstract":"BACKGROUNDIntrinsic and extrinsic foot muscles contribute to foot and lower limb function. This knowledge provides opportunities to target these muscles in exercise and rehabilitation. However, a barrier is the limited understanding of how prescribed exercises affect muscle activation and force output. This study examined muscle activation and torque production about the metatarsophalangeal joints of intrinsic and extrinsic foot muscles during common foot strengthening exercises. The secondary aim was to determine whether the addition of a postural change (leaning forward) or addition of mass can further increase muscle activation and torque.METHODSFifteen healthy participants (9 males, 6 females; age = 36.5 ± 8 years, mean ± SD) participated. Muscle activation was measured using fine-wire electromyography (EMG) electrodes for 2 intrinsic and 2 extrinsic muscles, and surface EMG electrodes for 4 superficial muscles. Metatarsophalangeal joint torque was measured using a custom toe dynamometer. Participants attended one 90-min session and performed 16 exercises. Five included the addition of leaning forward and 3 the addition of mass (20% of participant's mass) to compare their effects on muscle activity and torque.RESULTSMuscle activation and metatarsophalangeal joint torque varied considerably across exercises. Both the addition of leaning forward and the addition of mass increased muscle activation and metatarsophalangeal joint torque, with the addition of leaning forward producing a 35% median increase in torque about the metatarsophalangeal joints.CONCLUSIONMany common exercises, despite high muscle activation, produce relatively low metatarsophalangeal joint torque, raising questions about their clinical value. Adding a forward lean significantly increases toe flexor muscle activity and torque, reaching levels greater than added mass and comparable to walking.","PeriodicalId":48897,"journal":{"name":"Journal of Sport and Health Science","volume":"6 1","pages":"101110"},"PeriodicalIF":11.7,"publicationDate":"2025-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145777293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aging weakens these stress-response systems, disrupting proteostasis and increasing vulnerability to sarcopenia. High-intensity training (HIT) can counteract these declines by activating protective pathways such as the HSP response. HSPs are highly responsive to stress, examining their regulation during aging is important, as altered HSP activity is linked to the progressive loss of muscle mass.METHODSThis study investigated the abundance and phosphorylation of HSPs in skeletal muscle from healthy, active young and older adults (n = 7 per group), assessed at baseline and again in the older group following 12 weeks of HIT. Using calibrated Western blotting on both whole-muscle homogenates and pooled single muscle fibres, we quantified HSP content and phosphorylation to determine how aging and exercise influence stress-responsive protein regulation at both the tissue and cellular levels.RESULTSIn whole muscle homogenates, HSPs (HSP72, HSP27, and αB-crystallin) did not differ between young and older adults, while higher phosphorylation of small HSPs (sHSPs): phospho-HSP27 at Serine15 (pHSP27 Ser15) and phospho-αB-crystallin at Serine59 (pαB-crystallin Ser59) (∼1.8-fold and ∼2.9-fold, respectively) were found in muscle from older adults, indicating higher cellular stress associated with aging. A 12-week HIT intervention in older adults reduced homogenate pHSP27 Ser15 and pαB-crystallin Ser59 abundances to similar levels found in young adults. Total HSPs typically displayed a distinct fiber-type profile in both age groups, with more in type I compared to type II fibers, distinguished by the presence of myosin heavy chain I (MHCI) or MHCII. Phosphorylation at pHSP27 Ser15 and pαB-crystallin Ser59 was not different between type I and type II fibers. The HIT in older adults decreased total and phosphorylated sHSPs in both type I and type II fibers but increased HSP72 in type I fibers.CONCLUSIONHIT has the potential to mitigate age-related cellular stress and modulate protein expression patterns in aging skeletal muscle and, perhaps, has the potential to delay age-related muscle decline, thereby improving muscle health in older adults.","PeriodicalId":48897,"journal":{"name":"Journal of Sport and Health Science","volume":"162 1","pages":"101111"},"PeriodicalIF":11.7,"publicationDate":"2025-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145777292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, increased life expectancy is accompanied by a decline in functional capacity and a heightened risk of age-related diseases, ultimately leading to reduced quality of life. Interventions that support physiological function in later life and hence extend healthspan are therefore of considerable importance. Among these, regular physical exercise is strongly associated with numerous health benefits and is recognized as a key strategy for promoting healthy aging and extending healthspan. In this review, we highlight the impact of an active lifestyle, particularly regular physical activity, on the major hallmarks of aging. These include genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis, impaired macroautophagy, deregulated nutrient sensing, mitochondrial dysfunction, cellular senescence, changes in the extracellular matrix, stem cell exhaustion, altered intercellular communication, chronic inflammation, dysbiosis, and psychosocial isolation. A deeper understanding of the mechanisms by which exercise confers these benefits will aid in enhancing both physical and mental health in the elderly and in mitigating the onset of aging-associated diseases.","PeriodicalId":48897,"journal":{"name":"Journal of Sport and Health Science","volume":"1 1","pages":"101108"},"PeriodicalIF":11.7,"publicationDate":"2025-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145688964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
