While short-term passive heat acclimation (e.g., ≤7 days of warm-water immersion) enhances whole-body heat loss in young adults, evidence of its efficacy in older adults is lacking. Thus, we examined whether 7-days warm-water immersion would improve whole-body heat loss in older adults.METHODSTwelve habitually active older men (median [IQR] age: 68 [64-73] years; peak oxygen uptake (V̇O2peak): 34.1 [29.4-36.1] mLO2·kg-1·min-1) completed 7 consecutive days of ~90-minutes warm-water immersion (~40 °C) with core (rectal) temperature clamped at ~38.5 °C for the final 60 minutes. Before and after the warm-water immersion intervention, whole-body total (evaporative + dry) heat loss was measured via direct calorimetry during three, 30-minute bouts of cycling at increasing fixed rates of metabolic heat production (150, 200, 250 W·m-2), each separated by 15-minutes rest, in a hot-dry environment (40 °C, ~13% relative humidity). Rectal temperature and heart rate were measured continuously.RESULTSFollowing 7 days of warm-water immersion, whole-body total heat loss was elevated by 23 [95% confidence interval: 14, 31] W·m-2 across exercise bouts (acclimation-effect: P < 0.001; interaction: P = 0.598). This was paralleled by reductions in core temperature and heart rate of 0.3 [0.2, 0.4] °C and 11 [8, 14] beats·min-1 (both, acclimation-effect: P < 0.001; interaction: P = 0.288), respectively.CONCLUSIONSSeven consecutive days of warm-water immersion improved whole-body heat loss and reduced core temperature and cardiovascular strain across light-to-vigorous intensity exercise in habitually active older men. Passive heat acclimation may be an efficacious alternative to exercise-heat acclimation to improve heat-loss capacity. Studies are warranted to assess effectiveness in more heat-vulnerable populations.","PeriodicalId":18500,"journal":{"name":"Medicine & Science in Sports & Exercise","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142988719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we present an objective validation of five generations of ActiGraph sensors to characterize potential differences in output arising from changes to hardware or firmware.METHODSAn orbital shaker generated accelerations from 0 to 3700 milli-g in a randomized order to test the wGT3X-BT, GT9X, CentrePoint Insight Watch (CPIW) 1.0 and 2.0, and the GT3X+ devices used in the 2011-2014 National Health and Nutrition Examination Survey (NHANES). Absolute (±50 milli-g) and relative (±5%) raw vector magnitude (VM) agreement to a NIST-calibrated accelerometer (3DM) was the primary outcome for static offset (delta from 3DM VM at 0 g), drift (delta VM start - minus end), and dynamic response.RESULTSWe observed inter-generation differences [(Mean ± SD) -27.5 ± 8.7 mg (GT9X) to 4.8 ± 32.0 mg (GT3X+)] and intra-generational variability in static offset that carried over to lower shaker accelerations (< ~1300 milli-g), but these variations were mitigated with post-hoc calibration or integrated units (e.g., counts, MIMS). All generations fell within the ±5% of the 3DM across the tested acceleration range and were within ±50 mg of the 3DM below 3000 milli-g's. Drift was small [0.91 ± 0.27 mg (GT3X+), 0.07 ± 0.31 mg (GT9X)] relative to ≥1000 milli-g VM signal.CONCLUSIONSUsing an orbital shaker and criterion accelerometer we found small differences in the raw output of five ActiGraph generations across a range of accelerations typical of free-living data. However, the devices largely fell within established limits of agreement to the NHANES GT3X+ devices and variability was minimized with auto-calibration or when data was expressed in MIMS or counts.","PeriodicalId":18500,"journal":{"name":"Medicine & Science in Sports & Exercise","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142988771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, it sought to explore the impact of exercise training on AD pathology, specifically focusing on the modulation of glial responses and the effects of OPC perivascular clustering.METHODSThree-month-old C57BL/6 and APP/PS1 mice were divided into four groups: wild-type sedentary, wild-type exercise, sedentary AD, and exercise AD groups. The Barnes maze test was conducted to analyze spatial learning and memory. Enzyme-linked immunosorbent assay (ELISA) analysis, Immunofluorescence staining, Fluro-Jade C staining, TUNEL staining, Sholl analysis, and 3D rendering analysis were employed to detect Aβ 1-42, tau hyperphosphorylation, typical amyloid plaques, abnormal tau phosphorylation, neuronal damage, apoptosis, neurodegeneration, microglial and astrocytic activation and phenotypic polarization, and OPC perivascular clustering.RESULTSBehavioral results revealed that long-term exercise training ameliorated cognitive deficits in APP/PS1 mice. Histopathological analysis showed a reduction in amyloid deposition and decreased tau hyperphosphorylation. Immunofluorescence and Fluro-Jade C staining indicated that exercise attenuated neuronal damage, degeneration, and apoptosis. Sholl and 3D rendering analysis demonstrated that exercise mitigated spatially dependent glial phenotypic changes surrounding amyloid plaques in the AD cortex and hippocampus. Further, immunofluorescence staining revealed that exercise alleviated plaque-associated glial changes in these regions. Exercise also alleviated the reduction of microglial SIRPα and reduced synaptic loss mediated by microglial and astrocyte phagocytosis. Lastly, exercise mitigated OPC senescence and cellular senescence-induced OPC perivascular clustering in AD mice.CONCLUSIONSExercise can counteract AD pathological features by modulating glial responses and reducing OPC senescence and perivascular clustering near amyloid plaques, highlighting its potential as a therapeutic strategy for AD.","PeriodicalId":18500,"journal":{"name":"Medicine & Science in Sports & Exercise","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142988766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The HG and LG groups underwent an 8-week gymnastics program with different levels of cognitive load, while the SC group participated in a static course. Pre- and post-intervention assessments included VSWM tests and simultaneous monitoring of PFC oxyhemoglobin (HbO) concentration.RESULTSThe results showed time-related improvements in response accuracy and d-prime (d') from the pretest to posttest for both the HG and LG groups but not for the SC group. Additionally, the HG group demonstrated higher response accuracy and d' compared to the SC group at the posttest. Although VSWM-related HbO concentration was higher during task conditions requiring higher WM load compared to low WM load, no intervention effect was found. Further correlation analysis controlling for intervention-related fitness changes revealed positive associations between time-related changes in VSWM performance (response accuracy and d') and HbO concentration across all participants, with a similar correlation between response accuracy and HbO remaining specifically in the HG group but not other groups.CONCLUSIONSThese findings suggest that a 8-week gymnastics program can enhance VSWM performance and such cognitive benefits may be maximized by incorporating higher cognitive loads into the intervention. Despite the positive correlations between time-related changes in PFC oxygenation and VSWM performance, the gymnastics programs did not alter task-related PFC oxygenation, suggesting that intervention-induced VSWM improvement may not be solely dependent on changes in task-related PFC oxygenation.","PeriodicalId":18500,"journal":{"name":"Medicine & Science in Sports & Exercise","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142988770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Limited evidence supports their accuracy in sedentary adults with overweight or obesity during controlled exercise interventions. The purpose of this study was to compare EE estimated by the ACSM walking equation versus EE measured by indirect calorimetry during a 24-week aerobic exercise intervention, and identify potential modulators for their accuracy.METHODSData from the exercising groups (8 or 20 kcal·kg body weight-1·week-1) of the E-MECHANIC study were utilized in this ancillary analysis (N = 103). Every 2 weeks for the initial 8 weeks and monthly thereafter, EE was measured via indirect calorimetry during absolute (2 mph, 0% grade) and relative (65-85% VO2peak) workload exercise. Resting metabolic rate, VO2peak, and body composition were assessed at baseline and follow-up. An EE offset factor (EOF) was calculated to express measured EE as a percentage of the estimated EE at each workload (EOF < 100% represents an overestimation of ACSM estimated EE).RESULTSThe accuracy of the equation decreased with increasing exercise workload (0.44%, 9.2%, and 20.3% overestimation at absolute, relative, and maximal workloads, respectively, at baseline) and overestimation of EE was greater after the exercise intervention. Furthermore, race, sex, age, fat mass, and VO2peak were identified as modulators for equation accuracy. Greater overestimation of EE was observed in Black compared to white females, particularly at lower exercise workloads.CONCLUSIONSThese findings support future efforts to improve the accuracy of metabolic equations, especially in diverse populations. Researchers should account for exercise efficiency adaptations when using metabolic equations to prescribe exercise precisely.","PeriodicalId":18500,"journal":{"name":"Medicine & Science in Sports & Exercise","volume":"64 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142439245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
