Thirty-two individuals, sixteen women with knee osteoarthritis(52.12±10.69)and sixteen healthy women(51.00±10.00)who were same age (±3yr), were evaluated on postural control as measured by a NeuroCom EquiTest. Outcomes included equilibrium scores, sensory analysis ratios, sway energy score, and latenciesfrom sensory organisationtest, motor control test, and adaptation testandwere examined using the independent t-test.Equilibrium scores (in condition 1: p=0.030, condition 3: p=0.019, condition 4: p=0.045, condition 5: p=0.010, condition 6: p=0.041, and Composite value: p=0.011), strategy score (Strategy 5: p= 0.015), sensory analysis ratios (vestibularratio: p=0.013 and managementratio: p=0.023), and latencies (largeforward: p=0.020 and comprehensivelatency: p=0.016) were significantly better in the healthy women group. The presence of knee OA had an impact on the sensory system's effectiveness and its utilization in postural control. Lower values of equilibrium scores, strategy scores, sensory analysis ratios for women knee OA group were evidence of larger displacements of the center of gravity in the forward–backward direction suggesting that women knee OA group was unable to maintain balance compared to healthy knee controls. Also, women with knee OA displayed a longer neuromuscular response latency to balance perturbations, indicating a reduced ability to begin in recover balance quickly following an unexpected disturbance. This observation should be taken into account in the fall prevention, especially, individuals should place in dynamic situations with conflicted sensory environment, as these are found in daily life.","PeriodicalId":36150,"journal":{"name":"European Journal of Human Movement","volume":"1 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73777021","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}

Whilelow-skilled performers benefit from a proximal external focus. Children seem to respond differently to adults regarding the effects of attentional focus on motor learning, and the cause of this difference remains unclear.The present study investigated the effects of the attentional focus distance on motor performance and learning of high-skilled children. Forty-five 8-years-old high-skilled children were divided into three groupswith different attentional focus distances (internal, proximalexternal and distal external). All participants practiced aninside-of-the-foot kick soccer task in 5 blocks of 10 trials. Motorperformance was assessed through absolute and variable errors before the practice (pre-test), immediately after the practice (post-test), and after 24-hours (retention test). As inferential analyses,we run an ANOVA two-way (3 groups x 3 times) for absolute and variable errors. For absolute error, there was aneffect in time (p< .0001), with improvement across practice and retention; also, the distal external group demonstrated lower absolute error than othergroups (p< .0001). In contrast,proximal external focus provides a lower variability inter-trials (but with a lower score)(p< .001).Our findings suggested that distal external attentional focus benefits motor performance and learning of skilled children.Practice and experience are the predominant factors in this interaction, as it happens in adults.Childhood characteristics seem not to influence this process.","PeriodicalId":36150,"journal":{"name":"European Journal of Human Movement","volume":"100 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74426294","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 aim of this study is to investigate whether foot posture differs according to gender and lower limb muscle strength in pre-adolescent swimmers. Pre-adolescent swimmers who were trained at least 8 hours in a week between the ages of 8-12 and who did not have a history of ankle disability and pain were included. The Foot Posture Index (FPI) was used to determine foot posture. The lower limb muscle strength was measured using hand dynamometer. According to FPI total scores, swimmers were divided into two groups as normal footed (n = 36) and pronated (n = 24). Twenty-nine female and 31 male swimmers (mean age F: 11.06±1.53; M: 11.05±1.68 years) participated in the study. Twenty-four subjects had prone foot posture (10 females, 14 males), while 36 subjects had normal foot postures (19 females, 17 males). There was no statistically significant difference between lower extremity muscle strengths (knee flexion-extension, ankle dorsi, and plantar flexion) between swimmers with normal foot posture and swimmers with the prone foot posture (p=0.608, p=0.613, p=0.592, p=0.895 ). In addition, FPI scores were similar by gender (p>0.05). This study revealed that pre-adolescent swimmers with different foot postures had similar lower extremity muscle strength and that foot posture did not differ by gender.","PeriodicalId":36150,"journal":{"name":"European Journal of Human Movement","volume":"68 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87911574","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}

In the 34th JECMAG, there were significant decreases in AATS and some apparatus scores compared with the 33rd JECMAG. Although the effect of apparatus scores changed according to the competition dynamics, the most important apparatus seemed to be the vault (2018) and parallel bars (2020).

Twenty-nine female handball players were categorized as centers (n=6), pivots (n=9), wings (n=8) or goalkeepers (n=16). Measurement of anthropometrics data including body height and mass, body mass index; knee muscle strength, scores on the lower limb vertical power (vPower), lower and upper limb performance and trunk extension endurance were determined and analyzed with respect to playing position. The goalkeepers had higher knee strength in than pivots, wingers, and centers (p<.001). Pivot players achieved higher vPower than wings, centers and goalkeepers (p=.011). In addition, goalkeepers and wings achieved higher vPower than centers (p<.001). No significant differences were observed in trunk extension endurance and upper limb performance results according to play positions. The pivots and wingers had better lower limb performance than goalkeepers and centers (p<.001). The present study concludes that depending on their play positions, there are differences in terms of anthropometric values, knee muscle strength, vertical power and lower extremity performance in elite handball players.

Sixty prehypertensive men and women aged 25 to 54 years were selected by purposive sampling, and randomly assigned into two experimental groups (15 males and 15 females) and two control groups (15 males and 15 females). Systolic and diastolic blood pressure, and resting heart rate were measured by digital sphygmomanometer and stress was measured using Markham mental pressure inventory. Then, the experimental groups completed tai chi training for 45 minutes, three days per week for 8 weeks, however, the control groups received no intervention. Twenty four hours after completing the training, the dependent variables were re-measured in the study groups. Factorial multivariate analysis of covariance was used for statistical analysis. The results showed that tai chi significantly decreased systolic blood pressure, resting heart rate, and stress in comparison with control group. Our study encourages and supports that a short style of tai chi is an effective way in improving cardiovascular responses and stress in prehypertensive individuals.","PeriodicalId":36150,"journal":{"name":"European Journal of Human Movement","volume":"62 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75940710","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}
