Participants were 40 male\u0000students (Mage = 13.6 years, SD = 0.7) from physical\u0000education classes of a Brazilian school. They were randomly divided into eight\u0000teams, which played four games of 24 minutes\u0000according to the rules of the under-14 category of the\u0000local Futsal Federation. From the games, a sample of 80 sequences of play involving passes were randomly selected, from the\u0000moment the ball carrier got possession of the ball until the moment he passed\u0000it. From the x and y coordinates of all outfield players’\u0000displacement, variability of running correlation, cross-correlation, centroid , and\u0000interpersonal distance were calculated as measures of dyadic interaction.\u0000Results showed that the interaction of passer and\u0000receiver dyads were more variable than the remaining dyads. Moreover, it was\u0000verified that the passer dyad had\u0000the highest variability. The findings enabled us to conclude that, from the attackers’ point of\u0000view, variability played a positive role. In addition, it appeared that the\u0000passer sought to disrupt the interaction with his defender to perform a pass\u0000more than his teammates did to receive it. It appears that the skills of\u0000passing and receiving in the sport of futsal imply the\u0000ability to vary.","PeriodicalId":49943,"journal":{"name":"Kinesiology","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42575060","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 aim of our study was to evaluate the mechanical characteristics of m. triceps surae in competitive runners through TMG measurement and analyze if there was a relationship with running economy (RE). Nine male runners completed the study (mean±SD: age 40.4±9.0 years, body height 176.2±4.9 cm, body mass 70.7±9.4 kg, 10-km time 39.8±5.9 min, VO2peak 56.9 ± 6.5 mL kg-1 min-1). Each subject visited the lab on two occasions with 72h of rest between the trials. On the first day, an incremental test was performed to determine their ventilatory thresholds and peak oxygen consumption. On the second day, RE was evaluated on a treadmill at the velocity of their first ventilatory threshold (VT1), and mechanical characteristics of the soleus and gastrocnemius muscles were analyzed with TMG. Significant differences were found between the economic and non-economic runners in m. soleus in delayed time (Td), contraction time (Tc), and maximal radial displacement of the muscle belly (Dm). Also, significant differences were found in contraction time (Tc) in medium calf (MC) and in half relaxation time (Tr) in lateral twin (LT). The main finding of our study was that the runners with better RE showed greater stiffness in the triceps surae muscles, an aspect that seems to be associated with better performance in athlete runners.Key words: running economy (RE), tensiomyography (TMG), m. triceps surae, m. gastrocnemius, m. soleus","PeriodicalId":49943,"journal":{"name":"Kinesiology","volume":"52 1","pages":"273-280"},"PeriodicalIF":1.2,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43786800","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}

In total, 162 soccer players (age = 20.6 ± 1.8 years) belonging to the same reserve team of a Spanish La Liga club participated in this study. Countermovement jump (CMJ) and 5 and 15 m sprints were assessed in each season at the start of the preseason (July), Test 1 (T1), and the start of the competitive period (September), Test 2 (T2), from the 1998 to 2013 seasons. Considering all seasons, a trivial change was found in the sprint (5 m, Effect Size [ES] = −0.01; ±0.11, most-likely; and 15 m, ES = 0.05; ±0.09, most-likely) and countermovement jump (CMJ) performances (ES = −0.03; ±0.07; most-likely) after the preseason, but this varied across the seasons. While the fastest players in 5 m and 15 m tests and the most powerful worsened their performances in sprinting capacity (ES = 0.53–0.65, small very-likely) and in jump ability (ES = −0.54; ±0.25, small very-likely), respectively, the slowest players and the less powerful improved their performance likely/most-likely (ES = −0.33 and −0.68, small and moderate) and very-likely (ES = 0.40; ±0.20, small) after the precompetitive period. The changes in CMJ and sprinting were trivial and trivial/small for all tactical positions. The changes in neuromuscular performance after the preseason were not stable across the seasons and varied depending on the initial performance level.

Seventeen male football players with cerebral palsy took part in this study (23.0±4.7 years, 65.9±9.5 kg, 168.8±5.9 cm). The repeated sprint ability (6×40-m sprints with a 20-second recovery) was evaluated to determine the best sprint time, mean sprint time, and percentage of sprint decrement. The difference in lactate concentration was determined using blood samples taken three minutes before and after testing. The Illinois Agility Test (IAT) was also used to assess players’ change of direction ability. The FT8 players had better performance (p<.01) in the best sprint time, mean sprint time and in the IAT scores compared to the players of the sport classes FT5/6. Players of the sport class FT7 also reached higher performance in the IAT compared to the players of the sport classes FT5/6 (p<.05). A significant correlation was found between the best sprint time and mean sprint time (r=.94, p<.01), the best sprint time and the IAT (r=.62, p<.01), and between the best sprint time and the difference in lactate concentration (r=-.51, p<.05).

Also, analysis of measured parameters, interpretation, and implementation in practice are postponed. Therefore, aim of this paper was to determine differences in the performance of slalom turns between three conditions using a relatively new technology that allows fast data collecting and analysis. Twenty kinematic variables were analysed for each turn (both the left and right) and 26 turns were executed in each condition. All turns were performed by a national skiing demonstrator. Differences were\u0000determined by MANOVA (F=71.3; p=.00). Tukey’s post-hoc test showed that\u0000the turns performed on the ski simulator differed in every variable from the turns performed in other two condition, and the free skiing turns differed from the corridor turns in the following variables: hip joint angle of abduction of the right leg in the left turn, p=.00; distance of the projection of the centre of mass relative to the right foot in the left turn, p=.00; hip joint angle of flexion of the left leg\u0000in the left turn, p=.02; hip joint angle of abduction of the left leg in the left turn, p=.01; distance of the projection of the centre of mass relative to the left foot in the left turn, p=.00; knee angle of flexion of the left leg in the right turn, p=.04). The kinematic parameters obtained using the XSENS suit during slalom turns performed on the ski simulator and ski slope suggested significant differences in the position of the lower extremities, which might be important for situational efficiency and technical performance. Our results can be used to improve the alpine skiing technique. They suggest more precise relations between space parameters, such as body position and the angles\u0000between different body segments during a slalom turn. Methodology of research and technology used could contribute to the development of new scientific approaches in biomechanical research of top-level sports.","PeriodicalId":49943,"journal":{"name":"Kinesiology","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2020-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43617323","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}
