Purpose. The aim of the study was to detect the immediate and late effects of using a smartphone for 30 consecutive minutes on dynamic balance in healthy adolescents. Methods. Overall, 96 healthy adolescents of both genders, aged 15–18 years, were randomly assigned to the study and the control group. The subjects in the study group used a smartphone for 30 consecutive minutes; smartphones were not allowed in the control group. A Biodex system was used to assess the dynamic balance initially, as well as immediately after and 1 hour after the intervention. Results. MANOVA test revealed that there were statistically significant differences in the overall stability index and anteroposterior stability index (p = 0.002 and 0.04, respectively), with a statistically insignificant difference in the mediolateral stability index (p = 0.46) within the study group. Significant differences were observed in the immediate measurements of both overall stability index and anteroposterior stability index (p = 0.0001 and 0.03, respectively), while statistically insignificant differences were noted in the measurements of mediolateral stability index between the groups. Conclusions. The dynamic balance decreased after 30 consecutive minutes of smartphone use, so care should be taken to avoid accidents while walking or performing other daily activities. This effect, however, disappeared 1 hour later.

Purpose. the aim of this study is to find the aspects that identify the self-organization cycle of beach handball and to compare these between genders. Methods. Overall, 13 elite matches of each gender were analysed. We observed each team during the game, considering the following variables: offensive phase, ball possession, and attack outcome. Results. A self-organization cycle was identified, characterized by a predominance of attack over defence. We found that ball possession changed constantly (> 84%) and the same behaviour occurred in both genders. the difference between genders was that male teams were more likely to throw (81% vs. 74%, p < 0.001) and score a spectacular goal (49% vs. 39%, p < 0.001) when compared with female teams. Conclusions. the self-organization cycle of beach handball involves a prevalence of attack over defence, with a higher probability of the offensive phase ending with a spectacular throw, and with a constant change of ball possession during the match (system attractors).

Purpose. This study aims at showing the effects in muscle activity and arm function under the influence of the inhibitory muscle technique of the Kinesio tape method in healthy muscles. Methods. Overall, 20 apparently healthy subjects underwent the procedures 3 times, in 3 different tape conditions: no tape, Kinesio tape, and non-elastic tape. The muscle activity was obtained in millivolts through electromyography on biceps brachii and deltoid during 3 specific tasks, and the arm function was determined in seconds with the Action research Arm Test, a standardized tool conceived to assess upper extremity function, divided into the subscales of grasp, grip, pinch, and gross movement. Results. The electromyography results and most of the Action research Arm Test dimensions did not show any statistically significant differences in any comparison ( p > 0.05) between the tape conditions. However, there could be a tendency to perform movements faster under the influence of the Kinesio tape, as implied in the dimensions of grip ( p = 0.01) and total ( p = 0.04) of the Action research Arm Test. Conclusions. The Kinesio tape inhibitory muscle technique and tape conditions did not evoke significant effects in muscle activity or arm function in apparently healthy muscles.

Purpose. the study aim was to verify if there were associations between performance-related physical fitness levels and the clustered cardiometabolic risk score among children and adolescents. Methods. the cross-sectional study involved 1200 (655 females) children and adolescents aged 7–17 years. Performance-related physical fitness levels (upper limb strength [ULS], lower limb strength [LLS], agility, speed, and cardiorespiratory fitness [CRF]) were evaluated and categorized as healthy or unhealthy levels. Waist circumference, systolic blood pressure, glucose, and blood lipoprotein (triglycerides, total cholesterol, and high-density lipoprotein cholesterol) were measured. the clustered cardiometabolic risk score constituted the sum of internationally-derived standardized values (z-scores) for each risk factor divided by 5. Associations between performance-related physical fitness levels and the clustered cardiometabolic risk score were determined with linear regression models. Results. Participants with healthy ULS levels exhibited a less favourable clustered cardiometabolic risk score, whereas healthy levels of LLS, agility (only in girls), and CRF (only in boys) were related with a more favourable clustered cardiometabolic risk score. ULS ( : –0.091 [95% CI: –0.120; –0.062]), LLS ( : –0.272 [95% CI: –0.368; –0.177]), and CRF ( : –0.218 [95% CI: –0.324; –0.112]) were inversely associated with the clustered cardiometabolic risk score, while agility ( : 0.112 [95% CI: 0.082; 0.142]) and speed ( : 0.079 [95% CI: 0.039; 0.119]) demonstrated a positive association with the clustered cardiometabolic risk score. Conclusions. Our results emphasize the importance of following moderate-to-vigorous physical activity guidelines to better develop physical fitness levels for the maintenance of cardiometabolic health during childhood and adolescence.

Purpose. The study described psychophysiological responses (perceived exertion, affective response) of women with polycystic ovary syndrome (PcOS) throughout 10 sessions of high-intensity interval training (HIIT). Methods. Overall, 12 physically inactive women with PcOS (age: 26.2 ± 4.1 years; body mass index: 28.5 ± 6.3 kg/m 2 ) performed 10 running HIIT sessions of 50 min [10 × 1-min intervals, 90% of maximal heat rate (HRmax); 3-min active recovery periods, 70% HRmax], including 5-min warm-up and cool-down, with 48-hour intervals. HRmax, rating of perceived exertion (RPE, Borg cR10 scale), and affective responses (Feeling Scale) were assessed in the last 10 s of each interval and recovery period. Each session responses were grouped into session parts (beginning, 1–3; middle, 4–7; end, 8–10) for intervals and recovery periods separately. The generalized estimating equation model served to compare %HRmax, RPE, and affective valence between session parts. Results. The intensities of intervals ( p < 0.001) and recovery ( p < 0.001) increased from session beginning to end, as did RPE of intervals ( p < 0.001) and recovery ( p < 0.001). Interval affective responses were lower at end compared with beginning ( p < 0.040). HIIT intensity (%HRmax) presented a small coefficient of variation (cV, ca. 3%); RPE exhibited medium cV (ca. 20%) between 10 HIIT sessions. Conclusions. Psychophysiological responses of physically inactive PcOS women to running HIIT demonstrate positive affective valence at the beginning of HIIT sessions. As the session progresses, affective valence decreases to neutral and RPE increases.

Purpose. The study aim was to analyse 1 × 1 small-sided games (SSGs) with and without floating players, in different pitch sizes. Methods. Ten U-12 soccer players were divided into 2 groups. Group 1 ( n = 4) performed 1 × 1 SSG and group 2 ( n = 6) performed 1 × 1 + 1 SSG. Field sizes of 5 × 10 m (SSG1), 10 × 15 m (SSG2), and 15 × 20 m (SSG3) were used, all with small goals. The studied variables were heart rate (HR), total distance, explosive distance (> 12 km/h), accelerations, decelerations, maximum sprint, player load (PL) intensity and volume. The data were collected through WIMU PROTM and analysed with IbM SPSS Statistics. Descriptive analyses and comparisons between the effects of internal and external PL and SSG were performed with the Mann-Whitney U test. Results. Increasing the pitch size in 1 × 1 and 1 × 1 + 1 SSGs led to raised total distance, maximum sprint, and PL. In 1 × 1 and 1 × 1 + 1 SSGs, the time practice was predominantly associated with HR max intervals above 90%. Statistically sig ni ficant differences were observed between 1 × 1 and 1 × 1 + 1 SSGs in explosive distance (SSG2: 46.40 ± 5.07 / 28.99 ± 4.93, p = 0.02, ES( r ) = 0.82), PL intensity (SSG2: 2.03 ± 0.11 / 1.78 ± 0.12, p = 0.02, ES( r ) = 0.82), HR max (SSG1: 189.50 ± 1.91 / 199.50 ± 2.38, p = 0.01, ES( r ) = 0.82), and HR mean (SSG1: 174.50 ± 3.31 / 181.75 ± 2.21, p = 0.01, ES( r ) = 0.82). Floating players’ physical and physiological demands were lower compared with the other athletes. Conclusions. The pitch size influences the physiological and physical response of young soccer players in SSGs. The demand of 1 × 1 SSG is higher compared with 1 × 1 + 1. Floating player participation could result in a fruitful strategy to adjust the training intensity of specific soccer players.

Purpose. this study aimed to analyse the effect of an implicit-explicit hybrid learning model on declarative and procedural tactical knowledge of young school handball players. Methods. Overall, 30 female handball players (mean age: 13.03 ± 0.75 years) from 2 school teams participated in 25 handball training sessions involving activities focused on both implicit and explicit learning. Declarative knowledge was assessed by using the players’ analyses of 15 handball video scenes, while procedural knowledge was assessed by analysing the players’ actions during a 3 vs. 3 ball possession game. Results. the results showed a significant increase in declarative knowledge (t(23) = –4.228; p < 0.001; d = 0.863) but not in procedural knowledge (p > 0.05). Conclusions. We concluded that the Iniciação Esportiva Universal model improved the declarative knowledge of school handball athletes.

Purpose. This study aimed to analyse the correlations between individual technical determinants and the overall team performance in rink hockey sport. Methods. Retrospective observational data were collected from 182 matches played by 14 teams competing at the first division of the Portuguese national senior rink hockey championship (full season, 2018/19). Goals scored, goals conceded, direct free-hits, penalties, and final classifications were collected by team, on the basis of the official scoresheets of the games, validated by the official referees. Results. The results revealed that direct free-hits were more prevalent, although teams were more effective on penalties (40.4%) than direct free-hits (27.1%). Strong inverse relationships between direct free-hits effectiveness and final classification in the league ( r = –0.71, p = 0.004) as well as penalties ( r = –0.58, p = 0.029) were found. The effectiveness of the technical determinants, penalties, and direct free-hits increased with the proficiency of the teams in the classification. How-ever, the bottom teams experienced significantly higher weights of these technical determinants on the team’s total goals scored (1 st –4 th : 15.3%, 5 th –9 th : 25.6%, 10 th –14 th : 23.9%; p < 0.05). individual technical determinants’ effectiveness was a strong predictor of team performance, accounting for at least 22.1% of the total goals scored in the full season, highlighting athletes’ specialization in the training process.
目的。本研究旨在分析个人技术决定因素与冰场曲棍球运动整体团队表现之间的相关性。方法。回顾性观察数据收集了参加葡萄牙国家高级冰壶锦标赛第一级联赛的14支球队的182场比赛(2018/19赛季)。进球、失球、直接任意球、点球和最终分类由各队根据比赛的官方记分表收集，并由官方裁判验证。结果。结果显示，直接任意球更普遍，尽管球队在点球方面的效率(40.4%)高于直接任意球(27.1%)。直接罚球效率与联赛最终得分(r = -0.71, p = 0.004)以及罚球(r = -0.58, p = 0.029)之间存在很强的负相关关系。技术决定因素、罚球和直接任意球的有效性随着球队在分类中的熟练程度而提高。然而，排名靠后的球队在这些技术因素对球队总进球数的影响权重显著更高(第1 -4名:15.3%，第5 -9名:25.6%，第10 -14名:23.9%;P < 0.05)。个人技术决定因素的有效性是球队表现的一个强有力的预测指标，至少占整个赛季总进球数的22.1%，突出了运动员在训练过程中的专业化。

This study aimed to analyse the correlations between individual technical determinants and the overall team performance in rink hockey sport. Methods. Retrospective observational data were collected from 182 matches played by 14 teams competing at the first division of the Portuguese national senior rink hockey championship (full season, 2018/19). Goals scored, goals conceded, direct free-hits, penalties, and final classifications were collected by team, on the basis of the official scoresheets of the games, validated by the official referees. Results. The results revealed that direct free-hits were more prevalent, although teams were more effective on penalties (40.4%) than direct free-hits (27.1%). Strong inverse relationships between direct free-hits effectiveness and final classification in the league ( r = –0.71, p = 0.004) as well as penalties ( r = –0.58, p = 0.029) were found. The effectiveness of the technical determinants, penalties, and direct free-hits increased with the proficiency of the teams in the classification. How-ever, the bottom teams experienced significantly higher weights of these technical determinants on the team’s total goals scored (1 st –4 th : 15.3%, 5 th –9 th : 25.6%, 10 th –14 th : 23.9%; p < 0.05). individual technical determinants’ effectiveness was a strong predictor of team performance, accounting for at least 22.1% of the total goals scored in the full season, highlighting athletes’ specialization in the training process.","PeriodicalId":35354,"journal":{"name":"Human Movement","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71100739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose. Decision-making is the process through which players choose the most appropriate action to perform in the play. Previous investigations did not clearly portray the specific decisional background of learning players considering the progressing state of their capabilities and game knowledge. The study aimed to describe significant information picked up in situ and how young soccer players applied it to make decisions in the play. Methods. Three male soccer players aged 14 years were interviewed after 2 official district championship games in Portugal. Their games were filmed; the video sequences showing offensive actions were extracted and edited for visualization. before questioning, each sequence was visualized for recalling the game actions. The explicitation interview technique was used to help the athletes describe in detail their recalled actions. In line with the recommendation in similar studies, a content analysis of the interviews was conducted to identify the decisional background and the links between elements of information picked up in situ and the decision itself. Results. The players did not perform a detailed judgement for every decision and were influenced by direct constraints such as opponent pressure. In contrast, they occasionally assessed risks and opportunities emerging in the game depending on their colleagues’ actions and the pitch zone. At times, they relied on their imagination of what their teammates would do with the action outcome. Conclusions. Key elements of the decisional background are common among learning players and can be used as a reference for further investigation or practical intervention in game teaching.

Purpose. resisted and assisted in-water training methods are often employed in swimming training but their effectiveness remains unsubstantiated for different strokes and age groups. the study aim was to quantify the effects of a 3-week combined assisted and resisted in-water training program on 50and 100-m adolescent backstroke performance. Methods. In addition to regular swimming training, 9 (5 male, 4 female; age: 15.4 ± 1.7 years; 50-m backstroke FINA points: 346 ± 142) competitive backstroke swimmers performed a combined in-water machine-resisted and bungee-assisted training program 3 days/week with 3 resisted and 3 assisted 25-m sprints per session. before and after the 3-week training, 50and 100-m backstroke time trials were undertaken, with stroke rate, heart rate, and rating of perceived exertion collected. Results. there was a significant small improvement in 100-m backstroke times (3.4 ± 3.4% faster; ES = 0.27, p < 0.01), but only a trivial improvement in 50-m backstroke times (1.0 ± 3.1% faster; ES = 0.07, p = 0.19). Females had substantially greater improvements than males in both 50-m (2.4 ± 2.7% faster vs. –0.2 ± 3.2% slower) and 100-m (5.1 ± 2.6% faster vs. 2.0 ± 3.5% faster) backstroke time trials, but with the small sample size, this warrants further investigation. Conclusions. We demonstrated that adding a 3-week combined in-water resisted and assisted training was likely more beneficial for the longer 100-m distance; females seemed to benefit more than males.
目的。在游泳训练中经常采用抵抗和辅助的水中训练方法，但其对不同泳姿和年龄组的有效性尚未得到证实。这项研究的目的是量化为期三周的水中辅助和抵抗训练对青少年50米和100米仰泳成绩的影响。方法。除定期游泳训练外，9人(男5人，女4人;年龄:15.4±1.7岁;50米仰泳国际泳联得分:346±142)竞技仰泳运动员每周进行3天的水中机械阻力和蹦极辅助训练，每期进行3次阻力和3次辅助25米短跑。在3周训练前后，分别进行50米和100米仰泳计时试验，收集中风率、心率和感觉用力等级。结果。在100米仰泳时间上有明显的小幅改善(快3.4±3.4%);ES = 0.27, p < 0.01)，但在50米仰泳时间上仅略有改善(提高1.0±3.1%;ES = 0.07, p = 0.19)。女性在50米仰泳(快2.4±2.7%比慢-0.2±3.2%)和100米仰泳(快5.1±2.6%比快2.0±3.5%)的时间测试中均明显优于男性，但样本量较小，这值得进一步研究。结论。我们证明，增加为期3周的水中抵抗和辅助训练可能对长距离100米更有益;女性似乎比男性受益更多。
