Methods: Husserl's classic phenomenology was the methodological framework adopted. The phenomenological interview was carried out with an intentional sample that included six athletes with some type of physical disability and later its recording was transcribed for the procedures of phenomenological reduction and intentional crossing to explain the meaning of what is experienced by these athletes in mainstream sport. Results: Five categories essentially describe how these experiences occur: operational body barred in the world; shaping the movement; the invisibility of disability; determination stimulus; and normalization of social relations in mainstream sports. These experiences correspond to a dynamic process in which each part does not necessarily follow the other. Conclusion: The experience in mainstream sports allowed the interviewees to improve their experience of capacity, self-efficacy, and recognition through the mutuality between self-perception and the expectation of acceptance by society.","PeriodicalId":153884,"journal":{"name":"Motriz: Revista de Educação Física","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116663335","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}

However, the use of ECG is limited to laboratory environments, and new tools are needed for this purpose and that can be applied in the routine monitoring of individuals with SCI. The present study aimed to investigate the validity of the Polar V800 heart rate monitor in assessing the cardiac autonomic control of individuals with SCI. Methods: Nineteen adult men with SCI (paraplegia n = 10; 44.5 ± 8.5 years and tetraplegia n = 9; 34.4 ± 7.5 years) participated in this cross-sectional study. The participants remained in the sitting position at rest for 10 min for the acquisition of the ECG and Polar V800 signals. The last 5-min window was used to count the beat-by-beat R-R interval series and then calculate the HRV indices (linear methods in the time and frequency domains). The study subgroups were compared, and the validity of the measurements generated with a heart rate monitor was determined using the intraclass correlation coefficient (ICC2,1) and Bland-Altman graphs. Results: Agreement analyses for the R-R intervals, SDNN, rMSSD, PNN50, SD1, LF, HF, and LF: HF ratio tended to show reliability ranging from acceptable to excellent (ICC = 0.579-0.990; P = 0.043-0.001) and acceptably narrow limits of agreement within both the group with tetraplegia and the group with paraplegia. Conclusion: The Polar V800 heart rate monitor is a valid instrument for assessing HRV in individuals with paraplegia and tetraplegia.","PeriodicalId":153884,"journal":{"name":"Motriz: Revista de Educação Física","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115033763","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}

It is extremely important to establish normative values so that the handgrip strength is correctly interpreted in adolescents. The present study aims to establish normative values of handgrip strength (HGS) for adolescents, according to chronological age and sexual maturation. Methods: Data from three large projects carried out in Florianopolis and Sao Jose, Santa Catarina were used, corresponding to a sample of 2,637 adolescents aged 14 to 19 years old of both sexes (1,428 girls). The HGS of the right and left hands was measured by a manual dynamometer, and total HGS being defined by the sum of the left hand and the right-hand strength. Sexual maturation was determined by the development of pubic hair. The percentiles 3, 10, 15, 25, 50, 75, 85, 90, and 97 were calculated for the right, left, and total HGS. The percentile ranges p85 (high) were used. ANOVA and Kruskal-Wallis tests were applied. Results: In boys, the mean total HGS ranged from 67.5 ± 16.5 to 86.9 ± 21.8 (p < 0.001) and 74.3 ± 17.5 to 82.2 ± 17.8 (p < 0.001) for age and sexual maturation, respectively, while in girls the mean HGS total ranged from 48.8 ± 11.3 to 56.4 ± 16.0 (p = 0.127) and 47.8 ± 10.6 to 54.3 ± 12.3 (p < 0.001).

Methods: Six futsal players (age: 20.5 ± 7.4 years, height: 163.3 ± 16 cm, body mass: 57.9 ± 22 kg, maximum rate of oxygen consumption (VO2max): 42.0 ± 9 mL.kg.min−1) performed two experimental conditions in two days separated for at least 72h of interval: (1) one set of 10 min of SSG, 3x3 players; and (2) one set of 10 min of GG, 4 (1 joker) x 4 (1 joker) players. During each experimental session, the subject's HR values were monitored every 1 min of play. Pass, shot, dribbling, driving, and disarmament were recorded during the games. Results: There was no difference between SSG and GG for HR average (p = 0.50). The HR values that were recorded at the first minute of GG were higher than SSG (p = 0.02). The HRmax in SSG and GG were equivalent to 91.9% and 90.8% of HRmax of the incremental test, respectively. Total technical actions were higher in SSG (+ 18.4%, p = 0.001) than GG. Pass was higher in the SSG (+16%; p = 0.01) in comparison to GG. Conclusion: Both models were higher than HRmax equivalent to AT velocity.

Methods: In this observational longitudinal study, one hundred eighty-nine medical students completed an e-questionnaire, which used the WHOQOL-Bref instrument to report QoL and sociodemographic characteristics, health conditions, and lifestyles related to PA. Cronbach's alpha and Friedman/Dunn and Spearman's correlation tests were performed. Based on descriptive and inferential statistics, a multiple linear regression was used to evaluate the potential predictors of QoL. Results: The COVID-19 pandemic particularly affected the psychological and social domains. Time spent indoors and a non-ideal BMI had a negative impact on QoL. Being female and sexual minority-group membership were associated with lower QoL scores in the psychological and physical domains, respectively. Access to PA eTools was positively associated with QoL. Being monitored by a physical education teacher contributes to satisfactory PA levels during online classes. Conclusion: This study provides novel insights into the access of PA eTools on QoL during the COVID-19 pandemic. During periods of social distancing, people should pay extra attention to self-care strategies to protect mental health and promote positive lifestyle patterns. In addition, using online PA resources monitored by physical education teachers could be a strategy to maintain satisfactory levels of exercise.","PeriodicalId":153884,"journal":{"name":"Motriz: Revista de Educação Física","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132673776","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: Nineteen athletes, with an average age of 17 ± 1 years, participated in the study. The multicomponent training protocol was divided into technical, tactical, and physical practice for four weeks. The cardiac autonomic modulation was obtained through an electrocardiogram and blood pressure values were measured by a sphygmomanometer. The athletes answered the Pittsburgh questionnaire that assessed sleep patterns and issues. The VO2max was analyzed using the Intermittent Recovery Test Yo-Yo level 1. The RAST test was used to assess anaerobic power. Results: There was improvement in Heart Rate Variability (HRV) indicated by the increase in indexes, mean square root of the differences between normal cycles (RMSSD), low frequency increase (LF) (p = 0.04; d = 0.70), high frequency decrease (HF) (p = 0.01; d = 1.02) and the LF / HF sympathovagal index (p = 0.03; d = 0.70), variables related to faster recovery. An improvement in the components of sleep duration (p = 0.03) and quality (p = 0.02) of baseline and post-intervention sleep was also observed. Conclusion: The four-week multicomponent protocol contributed to improving VO2max, improving fatigue rates, quality of sleep, and maximum power.
