The sample consisted of 14 advanced female folk dancers at the age of 16–20 years. The participants’ static body balance was measured at the beginning (in the autumn) and at the end (in the spring) of the eight-month dancing period. Static body balance indicators were registered on a dynamographic platform within 30 seconds, standing on bipedal on stable and unstable support surface in eyes-open (EO) and eyes-closed (EC) conditions. The Flamingo test balance control, the balance control after spinning around and jumping tests were conducted only in EO condition. The following parameters were registered: the movements of the centre of pressure (CoP) in the anterior-posterior (AP) and medio-lateral (ML) dimensions; the length, speed and area of the trajectory. According to the study, folk dancers’ CoP movements in the AP and ML dimensions, measured in different conditions (EO, EC), on stable and unstable support surface, did not change significantly after the eight-month dancing practice. The young folk dancers’ static body balance, assessed by CoP movement trajectory, speed and area, improved considerably over the eight-month training period. Flamingo test results indicate that practising folk dance develops the young female folk dancers’ right and left side static stability equally. In the context of Estonian folk dance practice, including preparation for performing at dance festival, the young female folk dancers’ balance performance improved both in vestibular instability (spins, standing on unstable support surface and in EO condition) and fatigue (jumping test) conditions.","PeriodicalId":287636,"journal":{"name":"Acta Kinesiologiae Universitatis Tartuensis","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114754549","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}

Inclusion criteria were: a desire to cycle to work, residence more than 3 km from the workplace, and not physically active according to guidelines. There were 25 participants in the study and we provided them all with electrically assisted bicycles fitted with GPS bike computers to record usage. The participants were followed for three to eight months, 226 days on average. Measures of maximal oxygen uptake were performed before and after the intervention. Demographic characteristics and prior transportation habits were reported in a questionnaire at baseline. Participants cycled for 107.1± 62 min per week covering 37.6 ± 24 km per week. The distances cycled were significantly greater in the autumn (47.4 km/week, p=0.035) than in the spring (32.1 km/week). Participants cycled more on weekdays (7.1 km/day, p < 0.001) compared to weekends (0.9 km/day, p<0.001). Maximal oxygen uptake improved significantly, 2.4 ml/min/kg (7.7 %), p<0.001 and this was associated with cycling distance (r=0.49, p=0.042) and self-reported commuting distance (r=0.51, p=0.018). Offering electrically assisted bicycles to inactive employees may initiate transport-related physical activity and may give positive health effects.","PeriodicalId":287636,"journal":{"name":"Acta Kinesiologiae Universitatis Tartuensis","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121298377","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 present study aimed to investigate whether adolescents’ perception of autonomy-supportive behaviour from their peers is related to adolescents’ objectively measured LT moderate-to-vigorous physical activity (MVPA) through perceived psychological needs satisfaction and intrinsic motivation towards PA. School students (n=215) aged between 12 to 15 years old (age: 13.20±0.96 yrs) completed self-reported measures of perceived peers’ autonomy support, psychological needs satisfaction, and intrinsic motivation in the context of LT PA. In addition, study participants wore an accelerometer (Acti-Graph GT3X) to monitor their MVPA. Results of the structural equation modelling revealed that perceived autonomy support from peers had a significant and positive effect on perceptions of all three psychological need satisfaction in LT, which, in turn, had a significant and positive effect on adolescents’ intrinsic motivation. Adolescents’ LT PA was significantly predicted by their intrinsic motivation towards PA. Only one pathway through autonomy need satisfaction was revealed by which adolescents’ perception of their peers’ autonomy-supportive behaviour is related to intrinsic motivation and MVPA. The findings of the current study highlight the role of peers’ autonomy-supportive behaviour on adolescents objectively measured PA through motivational processes in the context of LT.","PeriodicalId":287636,"journal":{"name":"Acta Kinesiologiae Universitatis Tartuensis","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132873276","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}

Thirteen male soccer players (age: 22.8±1.8 yr, body mass: 75.1±11.9 kg, height: 1.80±0.08 m) participated in a repeated measure and cross-over design consisting of two conditions: three normal 30-m sprints (control) and two normal 30-m sprints divided by one 30-m sprint with the SpeedMaker™ (intervention). Kinematics were measured for each step together with the peak muscle activity of the hamstrings, quadriceps and gluteus during each stride of each 30-m sprint. The main findings were that sprinting with the SpeedMaker™ increased sprint times by 1.7% compared to normal 30-m sprints. However, no occurrence of a postactivation potentiation (PAP) response was found when performing a 30-m sprint with the SpeedMaker™ prior to a normal 30-m sprint in male soccer players. Furthermore, no detectable differences in step-by-step analysis on kinematics and muscle activity were found between the sprints with and without the SpeedMaker™. Only hamstrings and gluteus activity increased per stride over 30-m. It was concluded that the SpeedMaker™ did influence sprint times, but only in a small way that kinematics and muscle activity did not change detectable. Furthermore, that the SpeedMaker™ did not elicit a PAP effect. In addition, increased hamstring and gluteus maximus activation during the 30-m sprints suggests that these muscles are very important for acceleration, and that it is likely that acute hamstring strains occur when a soccer player is close to maximal velocity, as hamstring activation is maximal at that point.","PeriodicalId":287636,"journal":{"name":"Acta Kinesiologiae Universitatis Tartuensis","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122752725","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}

Previous studies have demonstrated that homozygotes of the minor AA allele had a reduced maximal oxygen consumption response to training compared to the common GG allele homozygotes, and that the ACSL A/G single nucleotide polymorphism explained 6.1% of the variance in the VO2max response to endurance training. The contribution of ACSL single nucleotide polymorphism to endurance trainability was shown in nonathletes, however, its potential role in professional athletes is not clear. Moreover, the genetic basis to anaerobic trainability is even less studied. Therefore, the aim of the present study was to examine the prevalence of ACSL single nucleotide polymorphism among professional Israeli long distance runners (n=59), middle distance runners (n=31), sprinters and jumpers (n=48) and non-athletic controls (n=60). The main finding of the present study was that the ACSL1 AA genotype, previously shown to be associated with reduced endurance trainability, was not higher among sprinters and jumpers (15%) compared to middle- (16%) and long-distance runners (15%). This suggests that in contrast to previous studies indicating that the ACSL1 single nucleotide polymorphism may influence endurance trainability among non-athletic individuals, the role of this polymorphism among professional athletes is still not clear.","PeriodicalId":287636,"journal":{"name":"Acta Kinesiologiae Universitatis Tartuensis","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124576218","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}
