Twenty-three participants (training age: 7.2 ± 3.5 years) completed a within-participant design, performing four sets of unilateral leg presses to momentary failure twice weekly for 8 weeks. In one leg, the knee flexion range of motion (ROM) was fixed at approximately 5-100°, while for the other leg, participants used their maximum individualized ROM (5-154 ± 7.8°). Quadriceps muscle thickness was assessed via B-mode ultrasonography in the proximal, central, and distal regions of the mid- and lateral thighs. Bayesian analyses were conducted to quantify treatment effects and provide inferential estimates using credible intervals and Bayes Factors (BF). Univariate and multivariate analyses indicated 'moderate' (BF = 0.14 to 0.22) and 'extreme' (BF < 0.01) evidence in support of the null hypothesis, respectively. Within-condition analyses revealed small-to-medium hypertrophic adaptation in both conditions, with absolute increases ranging from 1.08 mm to 1.91 mm. These findings suggest that both knee flexion ROMs are similarly effective for promoting quadriceps femoris muscle hypertrophy over a relatively short training-period in resistance-trained individuals.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"986-994"},"PeriodicalIF":2.3,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143670246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Instrumented mouthguards (iMGs) were worn by players competing in the 2023 Farah Palmer Cup season (13 teams, 217 players) during 441 player-matches. Maximum peak linear acceleration (PLA) and peak angular acceleration (PAA) per-event were used as estimates of in vivo HAE (HAEmax), linked to video analysis-derived contact-events and analysed using mixed-effects regression. Back-rows had the highest number of contact-events per full-match (44.1 [41.2 to 47.1]). No differences were apparent between front-five and centres, or between half-backs and outside-backs. The probability of higher HAEmax occurring was greatest in ball-carries, followed by tackles, defensive rucks and attacking rucks. Probability profiles were similar between positions but the difference in contact-events for each position influenced HAEmax exposure. Overall, most HAEmax were relatively low. For example, the probability of a back-row experiencing a PLA HAEmax ≥25g was 0.045 (0.037-0.054) for ball carries (1 in every 22 carries), translating to 1 in every 2.3 full games. This study presents the first in-depth analysis of contact-events and associated HAEmax in semi-elite women's rugby union.

Sprint-derived maximum torque (Tmax) was strongly correlated with torque intercepts for CP fresh (r = .558, p = .020) and after accumulated work (r = .556, p = .020). The cadence relationships demonstrated a large negative correlation between maximum cadence (Cmax) and optimum cadence (Copt) from the sprint test and the 15 s, 3 min and 12 min cadence recorded during CP after accumulated work (r = -0.541 to -0.634, p = 0.006 to 0.025).

LMMs identified both interactive and independent relationships on test indices. Interactions highlighted the influence of VTE generally reduced during peak-post maturational stages (- 0.5-2.5 YPHV), while maturational growth was predominantly more influential on performance development. Findings identified that lowered weekly VTE during maturational peak-post growth periods led to equivalent performance development. With maturational growth more influential, findings highlight the potential to misattribute longitudinal performance development toward training engagement and question the benefit of heightened physiological-focused engagement circa-post PHV stages.

Maximal 2000 m efforts for both ergometer and on-water (n = 340 of each) were collected from 162 national and international athletes (78 women, 84 men) over 16 years. A linear mixed model predicted on-water performance from static ergometer performance (physiological capability), accounting for day of on-water testing (environmental condition effects). On-water delta was the difference between predicted and actual on-water performance. The model revealed significant fixed effects (intercept = 17.70 s, 95% CI = [8.43, 26.97], p < 0.001; ergometer coefficient = 0.87, 95% CI = [0.81, 0.93], p < 0.001), and random effects for year ranged from -15.43 s to 47.98 s (median = -6.29 s). On-water delta ranged from -32.8 s (faster than predicted) to 51.1 s (slower). On-water delta provides a new dependent variable that can be used to quantify technical ability in future investigations. The current data provide contextual on-water delta values from a large sample of high-level athletes, and the outlined modelling approach can be applied to new datasets to provide population-specific quantifications of technical ability.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"1-9"},"PeriodicalIF":2.3,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143978553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inverse dynamics applied to the centre of mass provided accurate estimations of force-velocity relationship parameters (Pmax, F0, v0, SFV, xopt) and technical variables (RFmax, DRF). Somatic maturity was determined from peak height velocity (PHV). Performance increased with maturation in girls and boys (p < 0.001, d = 0.86‒2.78) accompanied by increases in relative Pmax from pre to post-PHV (p < 0.011‒0.001, d = 0.98‒5.20). Increases in relative Pmax were predominantly due to more velocity-oriented profiles (p < 0.007‒0.001, d = 0.76‒1.41). xopt, RFmax and DRF also increased with maturation (p < 0.030‒0.001, d = 0.87‒3.40). Pmax increases in girls and boys throughout maturation enabling them to reduce sprint times. Both girls and boys increased Pmax through a shift to more velocity-oriented profiles. However, plateaus in F0 and RFmax were present from pre-PHV in girls, while boys had slower development from mid-PHV. Improving Pmax through increases in F0 and RFmax, while maintaining a velocity-oriented profile, will likely benefit youth sprint performance.

Research has demonstrated that load-based biofeedback systems may be able to reduce the loading experienced during running, potentially decreasing injury occurrence or enhancing rehabilitation. This study aimed to examine if varying accelerometer location in a load-based visual biofeedback system altered participants ability to reduce loading (peak tibial and sacral accelerations). Participants (n = 27), were randomly divided into 1 of three conditions; tibial, sacral, or treadmill-based biofeedback. In each condition, participants ran for 6 minutes (baseline), followed by 10 minutes with biofeedback (location varying based on group), and for a further 6 minutes without biofeedback. Linear mixed models that included time and biofeedback location as fixed effects, and participants as a random effect, demonstrated a significant main effect for time (p < 0.001) and biofeedback location (p = 0.05) for peak tibial accelerations, and a significant effect of time for peak sacral accelerations (p < 0.001). Practically, it appears that all biofeedback locations were effective at reducing both tibial and sacral peak accelerations and may have utility in the prevention and rehabilitation of running injuries.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"1-9"},"PeriodicalIF":2.3,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143988495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
