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.","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":"71100852","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}

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.","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":"71101904","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}

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.

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.","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":"71102630","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}

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.","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":"71102733","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}

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.

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.","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":"71102926","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}

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.
