{"title":"Does mental fatigue affect performance in racket sports? A systematic review.","authors":"Cong Ding, Kim Geok Soh, He Sun, Samsilah Roslan, Shudian Cao, Yue Zhao","doi":"10.1186/s13102-024-00963-w","DOIUrl":"10.1186/s13102-024-00963-w","url":null,"abstract":"<p><p>Mental fatigue impairs performance across several sports domains. However, a systematic review on its effects on racket sports performance has been lacking due to the previous scarcity of studies. This review aims to provide a comprehensive review the effects of mental fatigue on racket players' performance, with a discussion of the underlying mechanisms. A thorough search was conducted across five databases, including Web of Science, PubMed, SCOPUS, SPORTDiscus (via EBSCOhost), and the Psychological and Behavioral Science Collection (via EBSCOhost). The PICOS framework established the inclusion criteria: (1) healthy racket sports players; (2) induction of mental fatigue in both field and laboratory settings; (3) comparison of mental fatigue interventions with a control group (e.g., watching a movie or reading a magazine); (4) assessment of performance outcomes, including physical performance, skilled performance, and perceptual-cognitive performance; and (5) randomized controlled trials (RCTs), non-randomized controlled trials (non-RCTs), and non-randomized non-controlled trials. Mental fatigue manipulation, subjective evaluation, and (neuro)physiological markers were synthesized to support the successful induction of mental fatigue. Performance was categorized into tennis, table tennis, badminton, and padel based on the characteristics of specific racket sports domains. Secondary outcomes, such as the rate perception of effort (RPE) and motivation, were synthesized to explain the mechanisms based on the prominent theory of the Psychobiological model of endurance performance. Six studies revealed that mental fatigue impacts stroke performance in table tennis, affecting speed, accuracy, faults, and only second-serve accuracy in tennis. The response time of psychomotor performance increased in table tennis, padel, and badminton. Meanwhile, mental fatigue increased the RPE and remained unchanged in heart rate, blood glucose, and lactate, consistent with the Psychobiological model of endurance performance. Additionally, attention is suggested as a significant underlying psychobiological factor.</p>","PeriodicalId":48585,"journal":{"name":"BMC Sports Science Medicine and Rehabilitation","volume":"16 1","pages":"179"},"PeriodicalIF":2.1,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11345983/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142074295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, KK athletes scored significantly lower in Freeze than in PI and KS groups. Research also suggests that KK athletes presented significantly lower overall scores in FFFS than PI individuals. Furthermore, the results of K-means cluster analysis indicated the existence of two distinct patterns of temperamental traits: (1) Cluster 1 suggests avoidance tendencies (high Flight and Freeze, and low BAS, BIS, and Fight levels); while (2) the Cluster 2 describes approach tendencies (high BIS, BAS and Fight scores, and low levels of Flight and Freeze).

This finding holds significance for coaches and sports instructors, suggesting that motivating karate athletes through incentives is more effective, while the use of punishment should be minimized during training. Additionally, the study proposes that the practice of Kyokushin karate has the potential to significantly diminish the freezing response in threatening situations and enhance overall fear management by reducing levels of the Fight-Flight-Freeze System (FFFS). Consequently, the Kyokushin karate style may be considered more advantageous than the Karate Shotokan (KS) style in these aspects, despite both styles contributing to the improvement of BAS. Given that a higher BAS is linked to positive emotions, optimism, and happiness, karate training emerges as a form of health intervention, acting as a preventive measure against mental disorders and promoting overall well-being.</p>","PeriodicalId":48585,"journal":{"name":"BMC Sports Science Medicine and Rehabilitation","volume":"16 1","pages":"178"},"PeriodicalIF":2.1,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11346272/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142074296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
