Twenty-three healthy young adults (23.8 ± 0.3 years) performed 7 trials in a randomized crossover fashion: CON (non-exercise control), K (on-ball kneeling, 5 min), fK (fragmented on-ball kneeling, 2 × 2.5 min), S (on-ball sitting, 5 min), fS (fragmented on-ball sitting, 2 × 2.5 min), SK (5-min sitting before 5-min kneeling) and KS (5-min kneeling before 5-min sitting). Arterial stiffness in Cardio-ankle vascular index (CAVI) was measured at baseline (BL), immediately (0 min), and every 10 min after exercise, and its changes from BL (ΔCAVI) were calculated. Area under curve (AUC) of ΔCAVI was calculated for SK and KS. The results showed that relative to CON, ΔCAVI decreased at 0 min and 10 min in K and fK, and remained decreased at 20 min in fK only. However, ΔCAVI in S and fS increased with time similarly, with no difference relative to CON. Though ΔCAVI decreased at 10 min in SK, it decreased at both 0 min and 10 min in KS, relative to CON. AUC of ΔCAVI was greater in KS than in SK. The study indicated that compared to continuous mode, fragmented kneeling results in more arterial stiffness improvements, while fragmented sitting exerts no additional effects. When kneeling and sitting are combined, kneeling before sitting elicits more arterial stiffness improvements than sitting before kneeling.","PeriodicalId":12005,"journal":{"name":"European Journal of Applied Physiology","volume":" ","pages":"1633-1640"},"PeriodicalIF":2.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143440058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Classification guidelines commonly refer to relative reliability, focusing on Pearson correlation coefficients (rp) and intraclass correlation coefficients (ICC). On those, the standard error of measurement (SEM) and the minimal detectable change (MDC) are often calculated in addition to the variability coefficient (CV). These, however, do not account for systematic or random errors (e.g., standardization problems). To illustrate, we applied common reliability statistics in sports science on simulated data which extended the sample size of two original counter-movement-jump sessions from (youth) elite basketball players. These show that excellent rp and ICC (≥ 0.9) without a systematic bias were accompanied by a mean absolute percentage error of over 20%. Furthermore, we showed that the ICC does not account for systematic errors and has only limited value for accuracy, which can cause misleading conclusions of data. While a simple re-organization of data caused an improvement in relative reliability and reduced limits of agreement meaningfully, systematic errors occurred. This example underlines the lack of validity and objectivity of commonly used ICC-based reliability statistics (SEM, MDC) to quantify the primary and secondary variance sources. After revealing several caveats in the literature (e.g., neglecting of the systematic and random error or not distinguishing between protocol and device reliability), we suggest a methodological approach to provide reliable data collections as a precondition for valid conclusions by, e.g., recommending pre-set acceptable measurement errors.","PeriodicalId":12005,"journal":{"name":"European Journal of Applied Physiology","volume":" ","pages":"1511-1526"},"PeriodicalIF":2.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12174282/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143406449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This inevitably has resulted in a lower number of repetitions performed in TS compared to CS, thereby leading to a suboptimal hypertrophic stimulus. The present study aimed to compare the impact of CS and TS protocols, both performed with the same number of sets and repetitions, but with loads adjusted to the same range of repetitions in reserve (RIR) on muscle hypertrophy.Methods: Ten resistance-trained volunteers (7 men and 3 women, 21.0 ± 1.5 years, 64.3 ± 6.9 kg, and 169.3 ± 6.2 cm) participated in this study. Participants performed two training protocols over an 8-week period, with two weekly sessions consisting of 5 sets of 12 repetitions of the leg press and leg extension exercises. The study employed a within-participant, unilateral design where one limb performed a TS protocol and the contralateral limb performed 3 clusters of 4 repetitions with a 20-s intra-set rest period of the same exercises (CS). Muscle thickness was assessed via ultrasound and thigh lean tissue mass was assessed by dual-energy X-ray absorptiometry pre- and post-study.Results: Results showed similar increases in muscle thickness (p < 0.001, ES = 0.56, and p = 0.012, ES = 0.42, respectively) and lean tissue mass (p = 0.002, ES = 0.11, and p < 0.001, ES = 0.13, respectively) in both CS and TS conditions.Conclusion: In conclusion, when sets, repetitions, and load adjustments were equalized based on RIR, a CS protocol elicits similar increases in muscle thickness and lean mass compared to a TS protocol.","PeriodicalId":12005,"journal":{"name":"European Journal of Applied Physiology","volume":" ","pages":"1725-1734"},"PeriodicalIF":2.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12174233/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143390177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ten articles provided reliability data, but only one articles under the appropriate conditions. Most studies sufficiently controlled nutrition during trials but not in the days leading to the trials or just before the trials. Thus, there is a paucity in protocols that combine justification and reliability with optimal nutritional support and mimic the true demands of a road-cycling race.

However, whether these impairments translate to changes in whole-body heat exchange during exercise-heat stress remains unknown. Therefore, following either a night of normal sleep or 24 h of sleep deprivation, 10 young men (mean (SD): 23 (3) years) completed three 30-min bouts of semi-recumbent cycling at increasing fixed rates of metabolic heat production (150, 200, 250 W/m2), each separated by a 15-min rest in dry heat (40 °C, ~ 13% relative humidity). Rates (W/m2) of whole-body total heat exchange (dry + evaporative) were measured continuously and expressed as peak responses [mean of the final 5-min of exercise at the highest metabolic heat production (250 W/m2)]. Body heat storage was quantified as the temporal summation of heat production and loss. Core temperature, indexed by rectal temperature, was measured continuously. Relative to normal sleep, sleep deprivation did not modify whole-body heat exchange (evaporative (-6 [-18, 5] W/m2; P = 0.245), or dry (7 [-5, 19] W/m2; P = 0.209; sleep deprivation-normal sleep mean difference [95%CIs]) and therefore total heat loss (1 [-14, 15] W/m2; P = 0.917).

A promising stimulus to improve microvascular health is ischemic conditioning (IC). We examined whether a single session of IC could improve microvascular reactivity to sPLM in young adults.Methods: This was a blinded, crossover, randomized clinical trial. Participants were seated in an isokinetic dynamometer that passively moved the knee 90° at a frequency of 1 Hz while superficial femoral artery leg blood flow (LBF) was measured. The absolute and the relative peak changes in LBF were calculated as the difference from baseline. The time to peak was calculated from the start of sPLM to peak LBF. The total area under the curve (AUC) was the sum of LBF above baseline during the hyperemic response. For IC, the cuff was placed around the dominant thigh and repetitively inflated (225 mmHg) for 5 min, then deflated for 5 min (total 45 min). For sham IC, the cuff was inflated to 25 mmHg. The sPLM response was re-assessed ten minutes after IC.Results: Twelve individuals completed the study (age 27 ± 3 years, 50% female). When controlling for resting LBF, heart rate, and sex, there was an interaction effect for absolute and relative peak change in LBF (p ≤ 0.048) but not time to peak or total AUC (p ≥ 0.17).Conclusion: We show an acute bout of IC may improve the peak vasodilatory response to sPLM, potentially due to \"preconditioning\" the microvasculature.","PeriodicalId":12005,"journal":{"name":"European Journal of Applied Physiology","volume":" ","pages":"1653-1663"},"PeriodicalIF":2.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143472440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
