This study aimed to analyse internal and external loads and the interactions between them during running legs before and after cycling in duathlon. Twenty-three male and female athletes participated in a simulated duathlon (5k-20k-5k). Internal workload was assessed using the rate of perceived exertion (RPE) and heart rate (maximum: HRMAX; average: HRAVG; R-R interval), whereas external workload was assessed using inertial sensors (Player Load by RealTrack, PLRT) attached to six body locations. The results showed that both running legs presented an increasing trend in RPE, HRMAX, and HRAVG throughout the kilometres, while the R–R interval decreased. The PLRT of the upper and lower back, knee, and ankle increased throughout the first running leg but not in the second. The PLRT was greater in the lower body than in the upper body because of energy absorption. RPE was higher in the second running leg than in the first leg. In conclusion, the cycling leg affects the internal and external load between running legs in duathlon. Load monitoring can help coaches understand duathletes’ performance and design specific training strategies to reduce fatigue during competition.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"23 1","pages":"15 - 30"},"PeriodicalIF":2.1,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49597862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quarter-finalists had a significantly greater number of possessions of 9 passes or more with a slow pass rate than teams eliminated at the group stage (p = 0.028), and they created shots from a significantly greater percentage of these (p = 0.007). Possession type had a significant influence on the percentage of possessions leading to a shot (p < 0.001). Possessions of 9 or more passes with a slow pass rate were the most productive. The percentage of these that led to a shot was significantly greater than for possessions with the same number of passes played at a higher pass rate (p < 0.002).

This intensive evaluation is in line with the assessment methodology proposed in the field of sports injury. Our results show no significant differences (p = 0.377) in the asymmetry of the step balance between players with/without a history of injury. However, there were differences when the player’s position was considered (p = 0.046). These findings confirm that the presence of a previous lower limb injury does not influence the asymmetry in lower limb step balance in male basketball players.

The study investigated 194 matches (74 women’s and 120 men’s matches) where at least one of the two competitors received the second shido. The penalties affected the attack frequency (F 2, 360 = 30.81, p < 0.001). The attack frequency was the highest after the second shido, while it was the lowest before athletes were penalised with the first shido. The increase in nage-waza attack frequency increased the possibility of winning a match twice (odds ratio (OR) = 2.01), and the increase in the number of ne-waza attacks per minute increased the possibility of winning a match 3 times (OR = 3.13). Moreover, the increase in the attack frequency especially following the second shido significantly increased the possibility of winning compared to previous penalties (OR = 1.13). Thus, the current study concludes that penalties affect match dynamics, and the change in the number and frequency of attacks affects match outcome. It is suggested that athletes should perform positive activities to increase the possibility of winning. Coaches could plan tactical trainings by taking the number of penalties into account.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"715 - 724"},"PeriodicalIF":2.1,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41865321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies on other team sports show that several feinting behaviours have the potential for great success against opponents. However, there is a gap in similar studies in handball. The aim of this study was to assess relevant performance factors of throwing feints in male elite handball. We used post-hoc video analysis to investigate what kind of throwing feints (jump vs. standing throw feint) were used in elite matches (n = 90), how successful they were, and if the handedness of the players affected the use and the outcome of a throwing feint. The results show that successful throwing feints generate a notable advantage against defensive play. A greater number of jump throw feints than standing throw feints are executed and the jump throw feints showed better results. The handedness of the players only marginally influenced the effectiveness of the feints and throwing feints were used sparingly by players. Throwing feints could be a performance-relevant skill to generate an advantage against the opponent; however, further research is needed to understand why they are used so rarely.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"725 - 736"},"PeriodicalIF":2.1,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42075879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Superiority, playing inferiority with Goalkeeper at goal (GK at goal), or Empty Net (EN) were the numerical contexts of players on the court studied. Results showed that teams tend to use 1st, 2nd, and 3er waves; to end with shots and to use a 3:3 (2 pivots) offensive system when playing during superiority. Teams performing inferiority context tend to end with a shot (but not score) when playing GK at goal and in turnovers when playing EN. Teams using the EN strategy tend to receive counterattacks after finalising their attacks. It can be concluded that teams showed a tendency of increasing the use of playing with EN during inferiority contexts. The coaches’ decision of changing the GK for a court player during inferiority needs to be trained to reduce the turnovers, and then the counterattacks received as a consequence.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"684 - 700"},"PeriodicalIF":2.1,"publicationDate":"2022-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45281529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data from 724 games (648 regular season games and 76 playoff games; 1448 data points) across five seasons were analysed using a two-level logistic regression analysis. The variables of interest were pace, fast breaks, legal stops, penalty throws given, 2-minute suspensions, and saves. The results indicated no meaningful differences in fast breaks, penalty throws given or number of saves, but did find signs of added intensity during the playoffs with a higher pace, more legal stops and more 2-minute suspensions. While the differences were not particularly large, they have the possibility of being practically meaningful and were in line with the axiom.
