However, multiple methods to implement eccentric training currently exist; they differ in execution and intended training adaptions. There is a clear differentiation between an eccentric muscle action and an eccentric motion whereby a motion alludes to a downward movement of an exercise. The proposed eccentric motions are dissipating eccentrics, deceleration eccentrics, overcoming eccentrics, maximal eccentrics, and rebound eccentrics. These motions formulate into training methods and cues to allow practitioners to clearly differentiate the various eccentric training methods used in research and practice. This review proposes a new conceptual framework that clearly outlines the different forms of eccentric motions that fall into a desired eccentric training method.","PeriodicalId":21993,"journal":{"name":"Strength and Conditioning Journal","volume":"867 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138530119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HIIT was significantly better than SSGs in the improvement of linear sprint ability (LSA) (standardized mean difference [SMD] = 0.35; p = 0.007). Within-group comparisons showed that both HIIT (SMD = 0.45; p = 0.0007) and SSGs (SMD = 0.27; p = 0.04) effectively improved LSA. There was no significant difference between HIIT and SSGs in the improvement of repeated sprint ability (RSA) (SMD = −0.05; p = 0.77). Within-group comparisons showed no significant differences but a larger effect size of HIIT (SMD = 0.36) than that of SSGs (SMD = 0.17). HIIT is superior to SSGs in improving LSA. Although HIIT is not the best training method for sprint ability, it improves aerobic capacity and speed performance, helping athletes save time and improve training efficiency. HIIT and SSGs have similar training effects on RSA.","PeriodicalId":21993,"journal":{"name":"Strength and Conditioning Journal","volume":"24 1","pages":"587 - 597"},"PeriodicalIF":2.5,"publicationDate":"2023-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91348202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT Quantifying training load is important to ensure that athletes correctly respond to training prescription and reduce injury risk. Training load can be divided into internal training load, the response of an individual to the training demand, and external training load, the physical “work” of the players. We aimed to analyze training load during a training week (microcycle) in soccer players. Systematic searches of 3 electronic databases (PubMed, SPORTDiscus, and Web of Science) were conducted, and Preferred Reporting Items for Systematic Review and Meta-analysis guidelines were followed. From 1,718 studies initially found, 16 were selected after screening. Descriptive and Z-score analyses were performed for each variable (acceleration and deceleration [DEC], average speed, high-speed running, sprint, total distance, player load, percentage of maximal heart rate, and rating of perceived exertion [RPE]). A sample of this review was 317 male soccer players aged 16.4–27.6 years, competing in elite, professional, and youth levels. Three days prior to match day was the most demanding session of the week, except for DEC, average speed, and player load demands. The day prior to match day was the least demanding session, except for sprint and RPE. In conclusion, midweek sessions can be chosen to apply higher training loads, whereas training sessions immediately before and after the match can be used to taper or recover.","PeriodicalId":21993,"journal":{"name":"Strength and Conditioning Journal","volume":"45 1","pages":"568 - 577"},"PeriodicalIF":2.5,"publicationDate":"2023-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47282703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT This systematic review and meta-analysis aims to provide meta-analytic estimates of the relationships between repeated sprint ability (RSA) outputs (total sprint time [TST] and fatigue scores) and aerobic capacity indicators (V̇O2max, the covered distance in the endurance shuttle run test [SRTdistance], and the velocity at the anaerobic lactate threshold [ALTvelocity]). To identify potential studies for inclusion, a search strategy was implemented on MEDLINE (through PubMed) and Web of Science. The correlation coefficients between RSA outputs and aerobic capacity indicators were extracted from the individual studies to reveal a pooled correlation. After the identification of studies providing inclusion criteria, 45 studies consisting of 1,488 accumulated participants were included. Meta-analysis showed the positive moderate relationships between TST and V̇O2max (pooled r = 0.444, p < 0.001), TST and SRTdistance (pooled r = 0.465, p < 0.001), TST and ALTvelocity (pooled r = 0.527, p < 0.001), RSA fatigue score and V̇O2max (pooled r = 0.449, p < 0.001), and RSA fatigue score and ALTvelocity (pooled r = 0.460, p < 0.001), which showed a low positive relationship between RSA fatigue score and SRTdistance (pooled r = 0.305, p = 0.029). This study showed pooled correlations between RSA outputs and practical aerobic capacity indicators. However, contrary to popular belief that there were stronger relationships, these relationships were low to moderate.","PeriodicalId":21993,"journal":{"name":"Strength and Conditioning Journal","volume":"45 1","pages":"462 - 474"},"PeriodicalIF":2.5,"publicationDate":"2023-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44840594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ability to maintain performance over a series of sprints is termed repeated-sprint ability (RSA). The physiological limiters of RSA include decreased force production capacity, insufficient energy supply, and metabolite accumulation. These limiting factors can be improved through repeated-sprint training, with greater RSA gains when performing this training with systemic hypoxia (i.e., reduced fraction of inspired oxygen). Exercising with blood flow restriction (BFR) causes localized hypoxia and a substantial metabolite load, which may provide an adjunct training method to improve RSA. Training with BFR augments muscular strength and adenosine triphosphate supply, which may improve subsequent sprint performance. Improved aerobic fitness, phosphocreatine resynthesis, and metabolite removal from BFR training could also enhance between-sprint recovery to resist fatigue. Despite the possible physiological benefits of repeated-sprint BFR training to improve RSA, there are no published reviews to collate this information. Therefore, this review proposes a theoretical framework for how BFR training could combat fatiguing factors and improve RSA based on current knowledge of the physiological impact of repeated-sprint training and BFR. Finally, guidance will be provided regarding how practitioners may implement BFR training to improve RSA.","PeriodicalId":21993,"journal":{"name":"Strength and Conditioning Journal","volume":"45 1","pages":"598 - 607"},"PeriodicalIF":2.5,"publicationDate":"2023-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42518695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Included and excluded studies were determined according to PICOS criteria. The search was performed on the electronic databases of Google Scholar, PubMed, and Scopus between September 1-7, 2022. The effect of combined strength training on vertical jump performance in basketball was compared with different training methods and as a result, a moderate effect was found in favor of combined strength training (ES=1.11, (95%CI 0.63-1.60), I2= 82%). As a result of systematic review and meta-analysis, it has been found that combined strength training applied in different forms in basketball is superior to other training methods in improving vertical jump performance. On the other hand, there is no superiority between the combined strength training protocols. Athletic performance specialists may improve jump performance by combining plyometric and traditional strength exercises in the same training season.","PeriodicalId":21993,"journal":{"name":"Strength and Conditioning Journal","volume":"45 1","pages":"554 - 567"},"PeriodicalIF":2.5,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42179662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These external loads may be carried in austere environments across unpredictable terrain. Like other tactical occupations (military, law enforcement, fire, and rescue), SAR loads can range from ≥20 to 45 kg. Not only are these loads known to cause a variety of injuries to the musculoskeletal, integumentary, and neurological systems of the carrier, but these loads are also known to impede task performance and have ultimately led to mission failure. Ensuring personnel are physically capable of carrying external loads on tasks is critical to mitigating these potential risks of injury and performance decrements. Optimal load carriage conditioning, following the known frequency, intensity, time, and type of training formula would see SAR personnel conduct a load carriage specific session every 7 to 14 days, with load weights, walking speeds, and durations akin to those typical of their SAR requirements. The terrain types (inclusive of grade and nature of terrain) should likewise form part of this conditioning process. In addition to load carriage-specific sessions, improving strength (notably relative strength) and aerobic fitness should also optimize the load carriage conditioning of SAR personnel.","PeriodicalId":21993,"journal":{"name":"Strength and Conditioning Journal","volume":"45 1","pages":"475 - 480"},"PeriodicalIF":2.5,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44362248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
