Abstract: Sutton, PJ, Mumford, PW, and Sunderland, KL. Workloads in collegiate women's lacrosse athletes during a Division II national championship season. J Strength Cond Res 38(9): 1651-1657, 2024-A comprehensive examination of the external and internal workloads in collegiate women's lacrosse athletes has yet to be reported. Thus, the primary purpose of this study was to determine the absolute and relative external and internal training and game workloads of National Collegiate Athletic Association (NCAA) Division II women's lacrosse athletes throughout an entire season. Data from 19 Division II women's lacrosse athletes were analyzed, encompassing each training session and game across an entire competitive season (February-May). External workloads were assessed using a wearable global positioning system, whereas internal workloads were determined through heart rate (HR) variables and session rating of perceived exertion. Game days were associated with significantly ( p < 0.05) greater absolute external and internal workloads. However, when comparing workloads relative to session duration, relative workloads between training and games were no longer significant ( p > 0.05) for total distance, high-speed running (≥15 km·h -1 ), HR-derived training impulse, or caloric expenditure. Nonetheless, relative sprint distance (>19 km·h -1 ) was significantly lower during games, whereas high-intensity accelerations (>2 m·s -2 ) and decelerations (<-2 m·s -2 ) were significantly greater during training compared with games ( p < 0.05). Practical applications of these findings suggest that coaches can better prepare athletes for game day conditions by adjusting training plans to replicate the duration and intensity of games. Overall, this comprehensive examination of internal and external workloads provides valuable data for coaches and practitioners to support performance comparisons, rehabilitation protocols, and workload analyses in collegiate women's lacrosse athletes.

Abstract: Duggan, JD, Byrne, P, Malone, S, Cooper, S-M, and Moody, J. The physical and physiological demands of intercounty camogie during competitive match-play. J Strength Cond Res 38(9): e510-e520, 2024-The aim of this study was to determine the physical and physiological demands of intercounty camogie match-play between positions and halves of play. Data were collected from 28 players during 18 competitive games using global positioning systems (10-Hz) and heart rate monitors (2.4-GHz). The study demonstrated that intercounty camogie players covered a total distance (TD) (m ± SD) of 6,040 ± 628 m, relative distance (RD) of 83 ± 13 m·min-1, and maximum speed of 25 ± 1 km·h-1. Furthermore, the players covered a mean sprint distance of 214 ± 112 m and 14 ± 6 sprints. Players' mean heart rate (HRmean) and HRmax was 138 ± 23 b·min-1 and 164 ± 20 b·min-1, respectively. There were decrements between halves in TD (p < 0.01, ES = -0.45), RD (p < 0.01, ES = -0.45), maximum speed (p < 0.05, ES = -0.18), HRmax (p < 0.05, ES = -0.23), running (p < 0.01, ES = -0.34), high-speed running (p < 0.01, ES = 0.34), sprinting (p < 0.01, ES = -0.10), HRmax (p < 0.05, ES = -0.23), and HRmax % (p < 0.05, ES = -0.24). Midfielders covered a greater TD compared with full-forwards (p < 0.05, ES = -0.38) and half-forwards (p < 0.05, ES = -0.38). Full-backs covered a significantly lower RD than midfielders (p < 0.05, ES = -1.2), half-backs compared with full-forwards (p < 0.05, ES = 1.14), and half-forwards compared with full-forwards (p < 0.05, ES = 1.15). Full-forwards covered significantly less RD when compared with half-backs (p < 0.05, ES = -1.14), midfielders (p < 0.05, ES = -1.47), and half-forwards (p < 0.05, ES = -1.15). The findings provide physical and physiological values on the match demands of intercounty camogie match-play.

Abstract: Gonçalves, DS, Moscaleski, LA, da Silva, GM, Morgans, R, Okano, AH, and Moreira, A. The effect of combined transcranial direct current stimulation and pneumatic compression as part of a comprehensive recovery strategy in professional male top-level soccer players. J Strength Cond Res 38(9): 1658-1666, 2024-This retrospective study aimed to examine the effect of transcranial direct current stimulation (tDCS) combined with lower limb pneumatic compression during the postmatch recovery period in top-level professional male soccer players' physiological and perceptual markers of recovery status. During the 2022 season (baseline), pneumatic compression was performed as part of the recovery strategy, applied the day after official match play and psychophysiological measurements (pain, sleep, perceived recovery, and creatine kinase [CK] sampling) were performed on the second day postmatch. During the 2023 season, the tDCS protocol was introduced, with its application being performed simultaneously (in conjunction) with pneumatic compression. Recovery sessions following 10 matches in the 2022 season and following 10 matches in the 2023 season were included in the analyses. Compared with 2022 (baseline; pneumatic compression isolated), the players perceived an increased recovery on the second day postmatch when tDCS was used in conjunction with the pneumatic compression (mean = 12%; p = 0.008) and rated improved sleep quality for the nights after applying tDCS combined with pneumatic compression (mean = 7.5%; p = 0.029). On the second day postmatch, a significant reduction was observed in muscle pain/soreness (mean = 64%; p < 0.0001) and the CK concentration decreased when baseline (pneumatic compression isolated) was compared with tDCS + pneumatic compression (mean = 76%; p = 0.001). In summary, combining pneumatic compression with tDCS may enhance the effects of both interventions, leading to greater overall improvements in recovery. Further research is warranted to confirm these findings and explore the underlying mechanisms in more detail.

Abstract: Díaz-García, J, López-Gajardo, MÁ, Parraca, JA, Batalla, N, López-Rodríguez, R, and Ring, C. Brain endurance training improves and maintains chest press and squat jump performance when fatigued. J Strength Cond Res 38(9): 1568-1575, 2024-Mental fatigue can impair resistance exercise performance. Brain endurance training (BET)-the addition of demanding cognitive tasks to standard exercise training-improves endurance exercise performance more than standard training. Although BET has yet to be evaluated with resistance exercise, it is expected to improve performance, particularly when the performer feels mentally fatigued. The study employed a pretest (week 0), midtest (week 3), posttest (week 6), and follow-up (week 9) design, with subjects randomized to BET ( n = 46) or control (exercise training) ( n = 45) groups. In testing sessions, subjects performed chest press and squat jump exercises to failure before (feeling fresh) and after (feeling tired) a 30-minute cognitively demanding Stroop task. Training comprised 5 BET or control training sessions per week for 6 weeks. In each training session, subjects completed 4 sets of each exercise to failure, with each exercise set preceded by a 3-minute cognitive task (BET) or rest (control). Exercise performance (number of repetitions to failure) and mental fatigue markers were assessed. In pretesting, exercise performance did not differ between the groups. In midtesting and posttesting, BET performed more chest press and squat jump repetitions when fatigued by the 30-minute Stroop than control. The mental fatigue elicited by the Stroop task gradually declined with training in BET compared with control. In conclusion, BET enhanced resistance exercise performance compared with standard training when tested subsequent to a mentally fatiguing cognitive task. These benefits were maintained weeks after training ended. Brain endurance training is an effective method to mitigate the deleterious effects of mental fatigue on resistance exercise performance.
摘要:Díaz-García, J、López-Gajardo, MÁ、Parraca, JA、Batalla, N、López-Rodríguez, R 和 Ring, C. 脑耐力训练可提高并保持疲劳时的胸外按压和蹲跳成绩。J Strength Cond Res XX(X):000-000,2024-精神疲劳会影响阻力运动成绩。脑耐力训练(BET)--在标准运动训练的基础上增加要求较高的认知任务--比标准训练更能提高耐力运动成绩。虽然 BET 还未在阻力运动中进行评估,但它有望提高运动成绩,尤其是当运动者感到精神疲劳时。研究采用了前测(第 0 周)、中测(第 3 周)、后测(第 6 周)和随访(第 9 周)的设计,受试者被随机分为 BET 组(n = 46)或对照组(运动训练)(n = 45)。在测试过程中,受试者分别在完成 30 分钟认知要求较高的 Stroop 任务之前(感觉新鲜)和之后(感觉疲惫)进行胸部下压和深蹲跳练习,直至失败。训练包括每周 5 次 BET 或对照组训练,为期 6 周。在每节训练课上,受试者完成每项运动的 4 组练习,直至失败,每组练习前进行 3 分钟的认知任务(BET)或休息(对照组)。对受试者的运动表现(失败重复次数)和心理疲劳指标进行评估。在测试前,两组的运动表现没有差异。在测试中期和测试后期,与对照组相比,BET 在 30 分钟的 Stroop 测试中疲劳时做了更多的胸部下压和蹲跳重复次数。与对照组相比,BET组在接受训练后由Stroop任务引起的精神疲劳逐渐减轻。总之,与标准训练相比,BET能提高阻力运动表现,即在进行精神疲劳认知任务测试后的阻力运动表现。这些益处在训练结束数周后仍能保持。脑耐力训练是一种有效的方法,可以减轻精神疲劳对阻力运动成绩的有害影响。

Abstract: Pairwise comparison of heavy dynamic strength and fast dynamic strength interventions on sprint performance: a systematic review and meta-analysis. J Strength Cond Res 38(9): 1675-1686, 2024-Previous studies have shown that both heavy dynamic strength (HDS) and fast dynamic strength (FDS) training can be used to improve sprint performance; however, a review and meta-analysis investigating pairwise studies that compare these two training interventions have not been performed. The aims of the study were to systematically review and analyze HDS and FDS training methodologies and evaluate their effect size difference, in pairwise comparison studies to determine and compare their effects on sprint performance. Databases were systematically searched using Boolean phrasing to identify eligible articles, and meta-analyses were performed on the extracted data. Seven studies met the inclusion criteria, which resulted in data from 138 subjects across 24 separate sprint assessments. Overall, there was a small effect in favor of FDS (standardized mean difference = 0.27, 95% confidence intervals [-0.07; 0.60], 95% prediction intervals [-1.01; 1.55]), but this was deemed not significant because of the wide-ranging prediction intervals. There is no distinguishable difference between HDS and FDS training on sprint performance. The wide-ranging prediction intervals suggest the variability is too great to determine whether one training type is more effective than the other. Practitioners should consider the individual needs of their athletes when deciding which training type to use for long-term sprint development.

Abstract: Loturco, I, Pereira, LA, Mercer, VP, Oliveira, LP, Zanetti, V, Lima, L, Bastos, T, Moura, TBMA, and McGuigan, MR. Jump squat vs. resisted sprint training programs applied to elite youth soccer players: effects on sprint and power-related performance. J Strength Cond Res XX(X): 000-000, 2024-This study examined the effectiveness of 2 different and widely used training programs on the sprint and power-related performance of youth soccer players. Two distinct training strategies-vertically oriented jump squats (JSs) or horizontally oriented resisted sprints (RSs)-were executed under the same absolute loading conditions (i.e., 30% of the athletes' body mass [BM]) during a 4-week preseason period. Training schemes, loading intensities (based on %BM), and the number of experimental sessions were designed in conjunction with the soccer club's coaching staff, considering the calendar, available resources, and regular training programs. Twenty-five under-17 soccer players performed a series of speed, power, and jump tests before and after 10 resisted training sessions, consisting solely of loaded JS or RS. Overall, neither group (i.e., JS or RS training groups) exhibited any improvement in linear sprint and change-of-direction (COD) speed. Conversely, vertical jumping ability and peak velocity in the loaded JS increased significantly only in the JS group, which may positively affect players' performance and training prescription during short soccer preseasons. Given the challenges in enhancing sprint speed among soccer players during preseasons (and even over the competitive season), coupled with the limited effectiveness of RS in improving sprinting, COD, and jumping capabilities within congested and short training phases (i.e., ≤4 weeks), the regular use of RS training methods during these phases may be highly questionable. Coaches should carefully consider these critical limitations and potential disadvantages when designing neuromuscular training programs for soccer players during the preparatory phases of the annual training season.

Overall, neither group (i.e., JS or RS training groups) exhibited any improvement in linear sprint and change-of-direction (COD) speed. Conversely, vertical jumping ability and peak velocity in the loaded JS increased significantly only in the JS group, which may positively affect players' performance and training prescription during short soccer preseasons. Given the challenges in enhancing sprint speed among soccer players during preseasons (and even over the competitive season), coupled with the limited effectiveness of RS in improving sprinting, COD, and jumping capabilities within congested and short training phases (i.e., ≤4 weeks), the regular use of RS training methods during these phases may be highly questionable. Coaches should carefully consider these critical limitations and potential disadvantages when designing neuromuscular training programs for soccer players during the preparatory phases of the annual training season.</p>","PeriodicalId":17129,"journal":{"name":"Journal of Strength and Conditioning Research","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142044005","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}

Abstract: Luders, J, Garrett, J, Gleadhill, S, Mathews, L, and Bennett, H. Comparative effects of complex contrast training and traditional training methods on physical performance within female, semiprofessional Australian Rules Football players. J Strength Cond Res XX(X): 000-000, 2024-This study aimed to explore whether complex contrast training (CCT) would elicit greater strength and power adaptations than traditional (TRAD) training methods using a volume- and intensity-matched design. Fourteen semiprofessional female Australian Football players completed the study. Both CCT and TRAD saw improvements in all performance outcomes: 1 repetition maximum (1RM) back squat (21.3 ± 8.2 and 16.7 ± 6.8 kg), 1RM bench press (5.3 ± 3.6 and 2.1 ± 4.0 kg), 1RM trap bar deadlift (5.0 ± 6.6 and 11.3 ± 2.5 kg), 5 m sprint (0.002 ± 0.09 and 0.02 ± 0.2 s), 10 m sprint (0.04 ± 0.17 and 0.02 ± 0.1 s), 15 m sprint (0.009 ± 0.15 and 0.08 ± 0.2 s), countermovement jump (CMJ) height (230 ± 150 and 340 ± 390 cm), CMJ absolute peak power (158.5 ± 69.6 and 235.6 ± 229.6 N), CMJ relative peak power (3.46 ± 4.1 and 2.68 ± 1.4 N·kg-1)), and plyometric push-up peak relative power (20.5 ± 13.4 and 15.2 ± 13.5 N). There were no between-group differences except for TRAD recording slightly greater improvements in 1RM Trap bar deadlift (Bayes factor [BF10] = 1.210). Complex contrast training completed sessions on average ∼7 minutes quicker than TRAD (BF10 = 5.722), while both groups reporting similar ratings of perceived exertion (RPE) with CCT (±SD) 58.4 ± 6.7 minutes and TRAD 65.5 ± 4.8. Based on the results, CCT training provides the same performance outcomes as traditional training methods across a period of 8 weeks, while taking less time to achieve these outcomes and with similar RPE.

Abstract: Allsopp, GL, Britto, FA, Wright, CR, and Deldicque, L. The effects of normobaric hypoxia on the acute physiological responses to resistance training: a narrative review. J Strength Cond Res XX(X): 000-000, 2024-Athletes have used altitude training for many years as a strategy to improve endurance performance. The use of resistance training in simulated altitude (normobaric hypoxia) is a growing strategy that aims to improve the hypertrophy and strength adaptations to training. An increasing breadth of research has characterized the acute physiological responses to resistance training in hypoxia, often with the goal to elucidate the mechanisms by which hypoxia may improve the training adaptations. There is currently no consensus on the overall effectiveness of hypoxic resistance training for strength and hypertrophy adaptations, nor the underlying biochemical pathways involved. There are, however, numerous interesting physiological responses that are amplified by performing resistance training in hypoxia. These include potential changes to the energy system contribution to exercise and alterations to the level of metabolic stress, hormone and cytokine production, autonomic regulation, and other hypoxia-induced cellular pathways. This review describes the foundational exercise physiology underpinning the acute responses to resistance training in normobaric hypoxia, potential applications to clinical populations, including training considerations for athletic populations. The review also presents a summary of the ideal training parameters to promote metabolic stress and associated training adaptations. There are currently many gaps in our understanding of the physiological responses to hypoxic resistance training, partly caused by the infancy of the research field and diversity of hypoxic and training parameters.
摘要:Allsopp、GL、Britto、FA、Wright、CR 和 Deldicque、L.常压缺氧对阻力训练急性生理反应的影响:叙述性综述。J Strength Cond Res XX(X):000-000,2024-多年来,运动员一直将高海拔训练作为提高耐力表现的一种策略。在模拟高海拔(常压缺氧)环境中进行阻力训练是一种不断发展的策略,旨在改善肥大和力量对训练的适应性。越来越多的研究对低氧环境下阻力训练的急性生理反应进行了描述,目的通常是阐明低氧环境可改善训练适应性的机制。目前,关于低氧阻力训练对力量和肥大适应性的总体效果,以及所涉及的潜在生化途径,还没有达成共识。不过,在缺氧条件下进行阻力训练会增强许多有趣的生理反应。这些反应包括能量系统对运动贡献的潜在变化、代谢压力水平的改变、激素和细胞因子的产生、自律神经调节以及其他缺氧诱导的细胞通路。本综述介绍了常压缺氧条件下阻力训练急性反应的基础运动生理学、对临床人群的潜在应用,包括运动员的训练注意事项。综述还总结了促进代谢压力和相关训练适应性的理想训练参数。目前,我们对缺氧阻力训练生理反应的认识还存在很多不足,部分原因是研究领域尚处于起步阶段,缺氧和训练参数也多种多样。

Abstract: Homer, KA, Cross, MR, and Helms, ER. A survey of resistance training practices among physique competitors during peak week. J Strength Cond Res XX(X): 000-000, 2024-Physique athletes are ranked by their on-stage presentation of muscle size, proportionality, and leanness. To acutely maximize muscle size, competitors manipulate resistance training (RT) variables in the days before the contest, commonly referred to as peak week (PW). Resistance training manipulations during PW may act synergistically with nutrition strategies such as carbohydrate loading. However, because little information exists on changes made to RT during PW, the purpose of this research was to determine the current practices of physique athletes and whether competitor characteristics were predictive of the RT variables manipulated. A total of 104 responses to the RT section of a survey on PW nutrition and training were analyzed through a series of multiple logistic regression models to examine the relationship between RT manipulations and competitor characteristics. Furthermore, to determine the magnitude of differences between PW and the week before PW (WBPW) for these variables, a McNemar-Bowker test, paired t-tests, and Wilcoxon signed-rank tests were conducted for nominal, continuous, and discrete outcomes, respectively. For all statistical analyses, p <0.05 was deemed significant. Competitors generally adjusted RT in a variety of ways, where proximity-to-failure was the most frequently manipulated and training frequency was the least; however, no competitor characteristic predicted any of the RT variables manipulated. Within those who manipulated RT variables during PW, frequency, volume, and intensity decreased while repetition ranges of compound exercises increased, empirically confirming that competitors seek to reduce training stress during PW. Such findings can be incorporated in future experimental designs examining the efficacy of peaking strategies to enhance the generalizability of results.
摘要:Homer、KA、Cross、MR 和 Helms、ER。高峰周体能训练实践调查。J Strength Cond Res XX(X):000-000,2024--健美运动员的排名取决于他们在舞台上展示的肌肉尺寸、比例和瘦度。为了最大限度地迅速增大肌肉体积,选手们会在比赛前几天(通常称为高峰周(PW))对阻力训练(RT)变量进行操作。在高峰周期间进行阻力训练可能会与碳水化合物负荷等营养策略产生协同作用。然而,由于有关在峰值周期间对阻力训练所做改变的信息很少,本研究的目的是确定体能运动员目前的做法,以及竞争对手的特征是否能预测所操作的阻力训练变量。研究人员通过一系列多元逻辑回归模型,分析了关于PW营养和训练调查中RT部分的104份回复,以研究RT操作与选手特征之间的关系。此外,为了确定PW和PW前一周(WBPW)之间这些变量的差异程度,分别对名义、连续和离散结果进行了McNemar-Bowker检验、配对t检验和Wilcoxon符号秩检验。所有统计分析的 p

Abstract: Ribeiro, N, Martinho, DV, Pereira, JR, Rebelo, A, Monasterio, X, Gonzalo-Skok, O, Valente-dos-Santos, J, and Tavares, F. Injury risk in elite young male soccer players: a review on the impact of growth, maturation, and workload. J Strength Cond Res XX(X): 000-000, 2024-The long-term development of young male soccer players involves a prolonged period of significant adjustments, highlighting the importance of studying the complex interaction between dynamic variables, including workload, and inherent elements like growth and maturity. This analysis examines the intricate connections involving the development, maturity, workload, and susceptibility to injuries among adolescent male soccer players. Significantly, these connections become prominent at the peak height velocity (PHV) period, a crucial moment in maturation. Growth rates vary among individuals, and higher rates have been associated with an increased risk of injury in young soccer players, particularly during periods of rapid growth. Identifying possible risk factors and understanding the complex connections between them is crucial to developing specific methods for reducing the risk of injury. Sharing this valuable information with essential stakeholders is crucial for guaranteeing young athletes' comprehensive growth and maturation process. Furthermore, this review emphasizes the immediate need for long-term studies and thorough injury analyses to comprehend better the dynamic interactions that influence injury patterns in young male soccer players. This review will allow practitioners to better understand the main modifiable and nonmodifiable risk factors for injury and provide essential information focusing on practical strategies, facilitating more informed decision making by all stakeholders. The review aims to clarify these complexities and offer crucial insights that can assist in designing and implementing efficient strategies to reduce the risk of injury, specifically for the challenges faced during PHV and within the broader framework of long-term athletic development in young soccer.
