The aim of this study was to compare the postural control of women with knee OA and healthy women peers and to determine the effect of knee OA on postural control. 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.

In adults, longitudinal external focus benefitsthe motor performance of high-skilled performers. 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.

The effect of head positioning is often not accounted for when optimising performance in the back squat exercise. The primary aim of the study was to identify the most advantageous head position for peak power (PP), peak velocity (PV) and peak force (PF) performance in the back squat exercise. A secondary aim was to identify the most favourable head position. Twenty male rugby union players performed 1x3 repetitions at 75% one repetition maximum (1RM) to determine their preferred pre-intervention head position, followed by 1x3 at 75% 1RM in a flexed (FP), extended (EP) and neutral (NP) neck position, performed in a counterbalanced and randomised order. PP, PV, PF and comfort level (CL) were measured during each repetition. FP resulted in significantly higher PP (3147.50 ± 464.70 W; p<0.05) compared to EP (2730 ± 427.83 W) and NP (2912.95 ± 441.16 W). However, NP resulted in significantly greater CL than FP and EP (3.65 ± 0.59; p<0.05). Therefore, when performing the back squat at 75% 1RM, the FP can be adopted to optimise power performance if there is no pain and no detriment to movement kinematics.

This study aimed to analyze and quantify relevant effects of competition on performance factors in female basketball players (16.45±0.92 years) according to age (under-16 and under-18) and playing positions: guards (n=19), forwards (n=27) and centres (n=22). Participants completed tests to measure jump capacity (countermovement jump-CMJ) and sprint times (10 m and 20 m) at three moments: just before thematch (T1), at half-time (T2) and after the match (T3). Associated with the increases of perceived effort, results showed “very likely” negative effects with performance decreased from T1-T3 in 20 m (4.03% and 3.51% for guards under-16 and under-18, respectively) and CMJ (15.17% and 13.7% for guards under-16 and forwards under-18, respectively). We only found a “large” ES in T2-T3 in guards under-16 in CMJ. Findings highlight the necessity to customize training, considering requirements and demands of different ages and playing positions to decrease the impact of fatigue after match.

Smartphone technologies are seen as a rapidly developing field of research in physical activity research. However, it is important to use smartphone applications that have proven validity and reliability in performance measurement. This study aimed to determine the validity and reliability of the My Lift mobile app used for the determining estimated 1RM for conventional deadlift and barbell back squat exercises. 10 male weightlifters (X"#$%: 17.50 ± 1.27 years) voluntarily participated in the study. For the conventional deadlift and barbell back squat movements of the weightlifters, My Lift app measurements were obtained during the 1RM test simultaneously with sub-maximal loads (75-85% 1RM).Results obtained from My Lift app and actual 1RM were compared with Bland-Altman plots. The My Lift app provided high reliability interclass correlation coefficient for conventional deadlift and barbell back squat (ICC = 0.99). The results were highly correlated obtained from My Lift app and the actual 1RM test (determination coefficient for conventional deadlift: R2= 0.99; barbell back squat: R2= 0.99).When compared with the actual 1RM test,My Lift app that used to determine estimated 1RM is a very valid and reliable tool.The My Lift app can be used by athletes and coaches as a practical and valid measurement tool for determining 1RM using sub-maximal loads

We investigated the reliability of fundamental movements in thirteen youth football players (mean age = 16.8 ± 0.6 y). Following a habituation warm-up, players performed three trials of stride-for-distance and bodyweight squats between two weeks. A motion tracking device was used to measure stride distance and squat depth. The weekly mean changes in mean and maximum performance were moderate for the stride (2.8%; 90% confidence interval: 1.1 to 4.5 and 3.6%; 2.1 to 5.2, respectively) and small for the squat (-2.7%; -12.3 to 7.9 and 3.3%; -5.2 to 12.6). ICCs for stride mean and maximum performance were moderate (0.74; 0.43 to 0.90) and high (0.76; 0.46 to 0.90), respectively, and low for the squat (0.22; -0.27 to 0.61 and 0.42; -0.04 to 0.74, respectively). Typical errors for mean and maximum performance were moderate for the stride (2.4%; 1.8 to 3.6 and 2.1%; 1.6 to 3.3, respectively) and large for the squat (15.9%; 11.8 to 25.1 and 13.1%; 9.7 to 20.5, respectively). The motion tracking reliability was encouraging in the stride. This finding warrants further investigation and consideration of the stride test for use in applied practice with a group of youth footballers.

Abnormal foot adaptations may affect muscle strength and may be associated with injury in athletes. 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.

To determine the effects of difficulty (D), execution (E), and total score of the apparatus on the all-around total score, and compare the scores of the 33rd and 34th Junior European Championships in Men’s Artistic Gymnastics (JECMAG). The data of the study are the all-around scores of the final of the 33rd (2018) and 34th (2020) JECMAG. The all-around total score (AATS), apparatus total score, D and E score of each apparatus were evaluated. A multiple regression was run to predict AATS2018 from the total score of the vault, pommel horse, horizontal bar, floor exercise, parallel bars, and AATS2020 from the parallel bars (p<.001). Multiple regression analysis was run to predict AATS2018 from scores of vault D, pommel horse D, vault E, horizontal bar E, horizontal bar D, pommel horse E, floor exercise D scores and AATS2020 from parallel bars D, parallel bars E, pommel horse E scores (p<.001). 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). It can be concluded that D scores were better predictors than E scores. Coaches can take these findings into account when determining competition strategies.

Coaches can take these findings into account when determining competition strategies.","PeriodicalId":36150,"journal":{"name":"European Journal of Human Movement","volume":"8 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91101593","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 purpose of the study was to compare anthropometric data and physical performance characteristics between different playing positions in professional female team handball. 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. Results indicate that knee muscle strength and height should be considered in handball performance, as well as the fat tissue in career performance, especially in females by professionals involved in the development process and selection of talent in young handball players.

Prehypertension seems to be the precursor to hypertension, and using non-pharmacological methods such as tai chi, can reduce blood pressure and its dangerous consequences. Therefore, this study aimed to examine the effects of 8-form Yang-style tai chi on cardiovascular responses and stress reduction in prehypertensive subjects. 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.
