ABSTRACT Few evidence-based guides exist to support coaches in delivering technical elements of cutting that may reduce the risk of anterior cruciate ligament (ACL) rupture. In isolation, balance exercises, jump landing, cutting movements, as well as modifying the penultimate step, may alter biomechanics favorably during this maneuver. By breaking this serial skill into its constituent parts, the coach is afforded an opportunity to observe trainable deficits, and allows the player more opportunity for practice. In addition, factors such as specificity to the direction of load during landings, alongside building capacity, and using externally focused cues may be crucial for adaptation and transference into open sporting scenarios.

ABSTRACT Taurine is a well-known free amino acid that has gained prominence in recent years despite its little or no role in protein formation. Few studies on the ergogenic effect of taurine exist with inconsistent results. This study aimed to reach a consensus about whether taurine supplementation is effective on aerobic and anaerobic performance outputs. Google Scholar, Pubmed databases, clinical trial websites, and grey literature were reviewed until November 2021. Mean differences were pooled using random or fixed-effects models according to the heterogeneity degree of related outcomes. Although 17 studies were detected for the meta-analysis between 2001-2021, 15 studies were grouped. Only randomized controlled trials were considered. Taurine supplementation had a significant effect on vertical (MD = 3.60; 95% CI [2.32 to 4.89], p < 0.00001) and countermovement (MD = 8.50; 95% CI [4.78 to 12.22], p < 0.00001) jump performance when compared to a placebo group. Taurine supplementation had no significant effect on V̇o2max level and rate of perceived exertion (respectively, MD = –0.54 mL/kg/min; 95% CI [–6.84 to 5.75], p = 0.87; MD = –0.24; 95% CI [–0.74 to 0.27], p = 0.35) when compared to a placebo group. Taurine improves potentially jumping performance and time to exhaustion.
牛磺酸是一种众所周知的游离氨基酸，尽管它在蛋白质形成中很少或没有作用，但近年来得到了重视。关于牛磺酸的自生作用的研究很少，结果也不一致。本研究旨在就补充牛磺酸是否对有氧和无氧性能输出有效达成共识。谷歌Scholar, Pubmed数据库，临床试验网站和灰色文献进行了审查，直到2021年11月。根据相关结果的异质性程度，采用随机或固定效应模型汇总平均差异。虽然在2001-2021年之间的荟萃分析中发现了17项研究，但有15项研究被分组。只考虑随机对照试验。添加牛磺酸对垂向鱼有显著影响(MD = 3.60;95% CI [2.32 ~ 4.89]， p < 0.00001)和反向运动(MD = 8.50;95% CI[4.78至12.22]，p < 0.00001)与安慰剂组相比，表现明显改善。补充牛磺酸对v_2max水平和感觉运动率无显著影响(MD = -0.54 mL/kg/min;95% CI [-6.84 ~ 5.75]， p = 0.87;Md = -0.24;95% CI[-0.74至0.27]，p = 0.35)。牛磺酸可以提高潜在的跳跃性能和消耗时间。

ABSTRACT Low back pain (LBP) is a significant problem in industrialized society with a considerable economic impact. There are many treatment approaches for LBP; however, many are expensive and possess questionable efficacy. An often-overlooked aspect of care for individuals with LBP is establishment of a positive therapeutic alliance. The therapeutic alliance essentially describes the relationship between the patient or client and practitioner that embodies trust, empathy, and mutual respect. Evidence suggests that when a positive therapeutic alliance exists, outcomes are improved. Unfortunately, practitioners are rarely instructed in how to specifically develop a positive therapeutic alliance. This article intends to highlight the overarching elements of establishing a therapeutic alliance for LBP management.

Supplemental Digital Content is Available in the Text. ABSTRACT To succeed in full contact combat sports like mixed martial arts, tae kwon do, and boxing, athletes must deliver a greater number of damaging strikes than they receive. Producing knockdowns, rendering unconsciousness, and scoring points can be accomplished through the application of high magnitudes of striking forces. There is evidence that striking forces can be enhanced through either nonspecific or specific strength and conditioning methods or a combination thereof. To better assist practitioners working with combat sport athletes, this article reviews current empirical evidence on how combat sport athletes respond to different methods of resistance training and offers practical recommendations for implementing nonspecific and specific exercises.

Cystic fibrosis (CF) is the most prevalent hereditary life-threatening disease in the Caucasian population. With the improvement in clinical care, individuals with CF are living longer, and CF-related diabetes (CFRD) has emerged as a major complication. The diagnosis of CFRD is associated with shortening survival, increasing morbidity, worsening physical capacity, and body composition. Engagement in exercise training has become a prominent nonpharmacologic intervention that aims to improve fitness and clinical outcomes in individuals with CF and CFRD. This column will specifically focus on the potential benefits of resistance training and provide recommendations for children and adolescents with CF and CFRD.

ABSTRACT The purpose of this brief review is to provide information about the effects of transcranial direct current stimulation (tDCS) on performance in resistance and power exercises commonly used by the strength and conditioning community. The authors aimed to identify all publications investigating the effects of tDCS on performance with dynamic constant external resistance and power exercises. The performance was analyzed based on the training volume, as the number of repetitions performed in an absolute or relative load (1 RM—%). In addition, the peak power output was also analyzed as a secondary outcome. Based on the eligibility criteria, 13 studies were found. The results showed that applying anodal tDCS on the left dorsolateral prefrontal cortex increased the training volume in exercises commonly used by the strength and conditioning community. However, anodal tDCS does not increase peak power output in upper and lower limbs. A discussion integrating tDCS into the resistance training based on the particular stimulated area was provided. Furthermore, this review provided some practical recommendations for the application of tDCS by coaches and practitioners of strength and conditioning.

ABSTRACT Interlimb asymmetries have been recently investigated in athletic populations. However, the effects of training interventions on interlimb asymmetries have been scarcely examined. Therefore, the aim of this study was to determine the effects of training interventions on changes in interlimb asymmetries from pre- to post-training. Furthermore, to examine the effects of training programs on intervention groups compared with control groups. A database search was completed (MEDLINE, CINAHL, and SPORTDiscus). Eight studies were then included in the meta-analysis. Results showed small reductions in interlimb asymmetries in single-leg broad jump (SLBJ) and change of direction (COD) speed from pre- to post-training interventions, whereas moderate effects were found in single-leg countermovement jump (SLCMJ) and SL lateral jump. When comparing the training interventions with the control groups, results showed small effects in favor of the training groups for reducing interlimb asymmetries in SLBJ and large effects in SLCMJ and COD speed. Thus, training interventions can evoke small to moderate reductions in interlimb asymmetries from pre- to post-training programs. Strength training performed unilaterally or bilaterally may elicit these reductions. Furthermore, training interventions showed larger effects compared with the control groups in reducing interlimb asymmetries. However, further research is needed.

: Soccer match-play dictates that players possess well-rounded physical capacities. Therefore, player physical development plans must consider developing several fitness components simultaneously. Effective individualization of training is likely facilitated with appropriate player profiling, therefore, developing a time-efficient and informative testing battery is highly relevant for practitioners. Advances in knowledge and technology over the last decade have resulted in refinements of the testing practices used by practitioners working in professional male and female soccer. Consequently, a contemporary approach to test selection and data analysis has progressively been adopted. Furthermore, the traditional approach of using a testing battery in a single day may now be outdated for full-time players, with a flexible approach to the scheduling of testing perhaps more suitable and time efficient. Here, guidance on testing for maximal aerobic, submaximal aerobic, linear and change of direction speed and stretch-shortening cycle performance (i.e., jump testing) are presented for male and female players, with emphasis on time efficient tests, while facilitating effective individualized training prescription. Normative and meaningful change data is presented to aid decision making and provide a reference point for practitioners. Finally, a time-efficient approach to scheduling fitness testing is presented, which complements daily training outcomes of a weekly periodization approach.

ABSTRACT Tensiomyography (TMG) is a noninvasive tool used to assess contractile tissue properties during an isometric muscle contraction. Owing to portability and versatility for assessing muscle parameters, TMG may be of value to the strength and conditioning (S&C) specialist. The purpose of this systematic review was to investigate the reliability of TMG measurements. PubMed, PEDro, MEDLINE, and Cochrane databases were searched up to September 2021 by 2 authors, who independently examined all titles and abstracts to determine initial eligibility. Inclusion criteria included any study assessing the reliability of TMG parameters, published in English, published in a peer-reviewed scientific journal, and included participants with no significant musculoskeletal conditions. Exclusion criteria included the following elements: TMG assessment process not clearly delineated, reliability of specific TMG parameters not clearly defined, and statistical methods for determining reliability not clearly defined. All studies underwent a quality assessment using the Modified Downs and Black checklist for assessing quality studies, and results were extracted from qualified articles. In total, 635 studies were identified, with 16 studies retained after full-text reviews. Twelve studies had poor quality, whereas 4 had fair quality. Noninvasive TMG has good to excellent absolute and interrater reliability for measuring the properties of skeletal muscles.
