Ten elderly (age = 78.21±14.82 years; males=4; females=6) and eleven young (age =24.25±12.43 years; males=6; females=5) participants of both genders performed five sit-to-stand and return-to-sit tasks consecutively by placing their feet on the Wii-Balance-Board; after two days of rest, they repeated the same assessment. The Wii-Balance- Board was positioned over the force plate to concurrently acquire the vertical component of ground reaction forces. Relevant kinetic and temporal parameters were estimated from these signals. Both the Wii-Balance-Board and force plate measurements resulted in a high level of correlation for almost all the parameters (Pearson’s product-moment r ranged from 0.91 to 0.99, p<.001) and, for the same parameters, intra-class correlation coefficients revealed a high level of agreement between the devices (ranged from 0.93 to 0.99). Bland-Altman plots and regression analysis detected systematic and fixed biases for two parameters (i.e., the inclination of force in standing and rising), while other parameters resulted with none systematic biases; the absolute magnitude of those differences was trivial or small (standardized biases ranged from 0.01 to 0.4). A high level of intra-device reliability was measured for all the parameters (intra-class correlation coefficients ranged from 0.85 to 0.99). The Wii-Balance-Board proved valid and reliable in comparison with a force plate for assessing transition movements so it can be considered a valuable solution for supporting the assessment procedures of average practitioners.","PeriodicalId":49943,"journal":{"name":"Kinesiology","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.26582/K.51.1.2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41649464","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}

Thirty-two healthy sports students participated in this study (age 19.8±1.4 years, body height 182.9±6.8 cm, body weight 79.1±8.1 kg). Morphological characteristics are represented with differences between the left and the right body side of: forearm girth, upper arm girth, calf girth, thigh girth, long shoulder height, lean mass of legs and lean mass of arms. The standing balance result was calculated as a result of factor scores for 9 measurements of 30 seconds (3 measurements of normal standing, 3 measurements of blind standing, and 3 measurements of deaf standing) collected from the pressure insoles system and the difference in ground reaction force between the left and the right leg. Results show that the asymmetric leg load in maintaining standing balance depends on the side differences in the thigh girth and upper arm girth. The greater difference in the thigh girth in favour of the left side resulted in bigger ground reaction force on the right leg compared to the left leg and the greater difference in the upper arm girth in favour of the left side resulted in bigger ground reaction force on the left leg. To avoid one side overload, it is essential for all sports activities to be performed bilaterally.","PeriodicalId":49943,"journal":{"name":"Kinesiology","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2019-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.26582/K.51.1.1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44326315","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}

Fourteen subjects performed\u0000a BW exercise protocol with (BW+V) and without (BW‒V) vibration in a randomized\u0000order. The BW exercise protocol consisted of three circuits of eight\u0000calisthenics-based exercises including prisoner squat, push-up, isometric\u0000squat, reverse dip, lunge, flutter kicks, isometric lunge, and T push-up. Vibratory\u0000frequency and amplitude were set at 40 Hz and 4 mm, respectively. Oxygen uptake\u0000(VO2), heart rate (HR), expired ventilation (VE), and\u0000blood lactate [La] were determined during the protocol and 30-minute recovery.

The individual-based variables were: minutes on court, effective field-goal percentage, free-throws/field-goals ratio, offensive rebound percentage, turnover percentage and playing position. The team-based variables were: team points minus opponent’s points (on and off court), NET score (player’s on values minus his/her off values), maximum negative and positive point difference, team’s winning percentage, game pace, defensive and offensive ratings. A two-step cluster analysis was performed to identify the player’s profiles during regular season and playoff games. The results identified five performance profiles during regular season games and four performance profiles during playoff games. The profiles identified were mainly characterized by the game quarter and the negative NET indicator (players’ performance on court minus their performance off court) in regular season games and the positive NET indicator during playoff games and second and third game-quarters.

Eleven physically active men performed, after the maximum oxygen consumption (VO(2)max) determination, SIT5s (16x5s with 24s of recovery) and SIT20s (4x20s with 120s of recovery) in random order on a cycle ergometer. Physiological, mechanical, and perceptual responses were evaluated during and after the sessions. The countermovement jump (CMJ) height and autonomic control of heart rate (HR) were evaluated before and after the sessions. Diet was also controlled through recall questionnaires. During the training, SIT5s exhibited greater HR, VO2, power output, and total work (TW) (p .05). A faster HR recovery (HRR) and a higher CMJ height were observed after the SIT5s (p .05). Some correlations between the mechanical and physiological responses were revealed only in the SIT5s. SIT5s was demonstrated to be more efficient as exhibited by greater mechanical responses associated with a higher aerobic activity, when compared to the volume-matched SIT protocol of longer sprints. Simple monitoring tools such as HRR and CMJ could help practitioners to detect differences in acute fatigue after different SIT sessions.","PeriodicalId":49943,"journal":{"name":"Kinesiology","volume":"50 1","pages":"137-148"},"PeriodicalIF":1.2,"publicationDate":"2018-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.26582/K.50.2.13","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43717224","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}
