Examining countermovement jump performance and dynamic balance among male high school athletes with varying levels of sports specialization. J Strength Cond Res XX(X): 000-000, 2025-Specializing at a young age may limit an athlete's motor development, since focusing on a single sport potentially exposes athletes to less variety of movements and neuromuscular demands. However, there are few studies examining the association between sport specialization and movement performance/control. The purpose of this study was to compare countermovement jump performance and dynamic balance among high school athletes of varying levels of sports specialization. 110 male high school athletes completed countermovement jump testing and the Y-Balance Test (YBT). Ground reaction forces were recorded during countermovement jumps and used to derive peak force, peak velocity, peak power, jump height, and the modified reactive strength index. Y-Balance Test composite scores were calculated to assess dynamic balance across multiple directions, for the dominant and non-dominant limbs. Athletes were grouped into high (n = 46), moderate (n = 39), and low (n = 25) specialization groups based on their sport participation habits. There were no between-group differences for any of the countermovement jump metrics (p > 0.05). For the YBT composite scores, there was not a group-by-limb interaction effect (p = 0.28); however, there was a main effect of group (p = 0.03). Post hoc tests indicated that the high specialization group exhibited lower YBT composite scores compared to the moderate specialization group (p = 0.01) and a trend toward lower scores compared to the low specialization group (p = 0.05). In general, highly specialized male athletes exhibited poorer dynamic balance compared to less specialized athletes.</p>","PeriodicalId":17129,"journal":{"name":"Journal of Strength and Conditioning Research","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144612207","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}

J Strength Cond Res XX(X): 000-000, 2025-This study examined the effects of a 12-week training intervention on drop jump kinetics in pre- and post-peak height velocity (PHV) boys. Forty boys from a range of sports, aged 9-17 years, were categorized into two maturity groups (pre- and post-PHV) and subdivided to an experimental (EXP) or control (CON) group. The EXP groups completed twice weekly combined traditional resistance and plyometric training program, whereas the CON groups continued regular sports activities. Drop jump ability was quantified by examining performance variables (jump height, ground contact time, and reactive strength index [RSI]), absolute and relative kinetic variables (force, impulse, and power), and movement strategy variables (spring-like correlation, peak center of mass [COM] displacement, and COM velocity). Differences in all variables were analyzed using 2 × 2 × 2 (maturity × group × time) mixed-model ANOVA. Statistical significance was determined as p < 0.05. There were significant maturity × group × time interactions observed for jump height, RSI, mean and peak breaking force, relative breaking force, net impulse, and for all absolute and relative power variables. The results indicate that maturity status influences responsiveness to combined training in boys, with the post-PHV group showing greater adaptations in drop jump performance than their less mature peers. Practitioners aiming to develop stretch-shortening cycle function in post-PHV youth should program a combination of resistance training and plyometrics.

Training impulse and session ratings of perceived exertion as perceived by athletes and observed by coaches during pre-season football camp. J Strength Cond Res XX(X): 000-000, 2025-Quantification of internal training load (TL), through wearable technology, represents an emerging metric for TL management in sport. The accuracy of subjective vs. objective assessments of TL, as perceived by athletes and observed by coaches, has yet to be evaluated during long-duration football practices (>2 hours). The purpose of this study was to evaluate relationships among objective heart rate (HR) and subjective ratings of perceived exertion (RPE) assessment of TL in collegiate American football athletes, and their coaches, during preseason camp. Twenty-four athletes (first-year, n = 6; returning, n = 18) and 2 coaches (football coach [FBC], n = 1; strength and conditioning coach [SCC], n = 1) participated. Athletes wore chest strap HR monitors during the first 6 days of preseason football camp for an objective TL assessment using training impulse (TRIMP: average exercise HR × duration of practice). Subjective TL was assessed by both athletes (perceived) and coaches (observed) using a session ratings of perceived exertion (sRPE; 0-10 rating scale; 10 = maximum effort). The average practice duration was 142.3 ± 35.5 minutes, with 139 total observations across 6 practices. Significant (alpha level p ≤ 0.05) relationships were noted between TRIMP and sRPE from the athletes (r = 0.62), FBC (r = 0.68) and SCC (r = 0.49). When subdivided into first-year and returning groups, relationships were stronger between TRIMP and sRPE with first-year athletes (athlete r = 0.68; p = 0.001; FBC r = 0.79; p = 0.001; SCC r = 0.64; p = 0.001) than for returning athletes (athlete r = 0.60; p = 0.001; FB coach r = 0.70; p = 0.001; SCC r = 0.40: p = 0.001). These data suggest that subjective athlete perceptions and coach observations of TL are in low-moderate agreement, indicating these are not interchangeable, during long-duration preseason football camp.</p>","PeriodicalId":17129,"journal":{"name":"Journal of Strength and Conditioning Research","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144612214","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}

This study aimed to (a) compare IMTP and CMJ kinetics between young weightlifters who did and did not attain national qualification and (b) identify kinetic variables that predict qualification. Thirty-seven young weightlifters were classified into 2 groups: those who qualified (QUAL; age = 17.1 ± 0.3 years, maturity offset = 3.13 ± 0.6 years, males = 15, females = 10) and those who did not qualify (DNQ; age = 15.8 ± 2.2 years, maturity offset = 2.7 ± 1.6 years, males = 6, females = 6). Subjects completed CMJ and IMTP tests on dual force plates. T-tests revealed that QUAL showed significantly (p < 0.05) higher relative force at minimum displacement (g = 0.82), average relative propulsive force (g = 1.76), and average propulsive velocity during the CMJ (g = 0.68), along with a shorter propulsive phase (g = -1.22). In the IMTP, QUAL demonstrated higher relative peak force. Statistical parametric mapping revealed greater relative vertical force at 69-88% of movement time in QUAL, indicating higher force during the CMJ propulsive phase.

Effects of lower extremity alignment during barbell squat training on muscle volumes.

Biomechanical studies demonstrate that hip muscle demands are different for squats performed with \"knees in\" vs. \"knees out\" tibiofemoral alignment. To: (a) determine whether these differences in hip muscle demands influence hip extensor muscle size adaptations and (b) examine the safety of these squat variations, training with \"knees in\" vs. \"knees out\" squats was compared. Eleven healthy women (\"knees in\": n = 6) completed 6 weeks' barbell squat training.

Surprisingly, gluteus maximus volume decreased in the \"knees in\" group (p = 0.045). Smaller gluteus maximus may indicate muscle atrophy or water loss concomitant to glycogen depletion. As the former indicates reduced and the latter increased muscle loading, \"knees in\" squat seems to affect gluteus maximus loading, although the direction of this change is unclear.

To simplify the strength assessment understanding, our purpose was to group force, velocity, and power metrics that could provide similar outcomes. We measured single-leg knee extensor strength under isometric and dynamic conditions on 64 young adults (33 men and 31 women). Subjects performed maximal and burst-like contractions under isometric conditions to assess maximal torque (MVT) and rate of torque development (RTD). Under dynamic conditions, a torque-velocity relationship was obtained from an incremental load test.

The purpose of this study was to establish mean/median values, proportions, and percentiles for hip and ankle joint range of motion, dynamic balance, and isometric hip strength in female preprofessional contemporary dancers. One hundred sixty-six dancers (mean age: 18.9 ± 1.83 years) participated in preseason screening at the beginning of 6 academic years (2015, 2018, 2019, and 2021-2023).

The primary aim of this cross-sectional study was to develop and validate a novel reactive agility test for judokas and to examine its test-retest reliability, validity, and discriminative validity. Thirty-four male judokas were recruited from the National Judo Team. The Ippon Reactive Agility Test (IpponRAT) was developed and evaluated in 3 stages, with its feasibility being assessed. The test measured key performance components, including movement time (MT), reaction time (RT), and decision-making time (DT). To assess test-retest reliability, subjects completed the IpponRAT in 2 separate sessions. To assess validity, its correlation with Special Judo Fitness Test (SJFT) was evaluated. Discriminative validity was evaluated by determining whether the test could discriminate judokas based on their competition level. The IpponRAT demonstrated high test-retest reliability for MT (intraclass correlation coefficient [ICC] = 0.82), and good reliability for RT (ICC = 0.71), but poor reliability for DT (ICC = 0.36). The IpponRAT MT showed a high correlation with the SJFT (r = 0.62, p < 0.001), whereas the IpponRAT DT showed a moderate correlation (r = 0.34, p < 0.05).
