Abstract Study aim: To investigate age-related changes in rhythmic reproduction ability in relation to the complexity of the adopted movement task. Material and methods: A Stereophotogrammetric system was used to quantify individual rhythmic performances through motion analysis. Seventeen younger adult (age: 34.8 ± 4.2 yrs) and sixteen older adult (age: 69.9 ± 3.8 yrs) sedentary individuals volunteered for this study. Participants were administered a rhythmic test, which included three different rhythmic patterns to be reproduced by means of finger-tapping, foot-tapping and walking. Number of correct reproductions, time delays and rhythmic ratios were assessed and submitted to analysis of variance. Results: For all rhythmic parameters, age-related differences emerged about rhythmic patterns and motor tasks. Older adults showed reduced accuracy as compared to their younger counterparts with a marked tendency to speed up beats reproduction (p < 0.05). Increased movement complexity negatively influenced rhythmic ability, with worst performances in the walking task (p < 0.05). Conclusions: Complexity of the motor reproduction worsen rhythmic ability. Future research should focus on how specific rhythmic training with progressive movement task complexity could contrast this age-related decline.

Abstract Study aim: To assess the effects of a long-term physical exercise program on balance, physical conditioning, and health perception in elderly women. Material and methods: The sample, 143 elderly women, were randomly assigned to an experimental group (EG; n = 71; age: 71.62 ± 4.96 years) and control group (CG; n = 72; age: 72.89 ± 5.40 years). The EG was submitted to a 32-week physical exercise program (3×/week, 60 min/session). Balance and physical conditioning were assessed through the 10-step in a straight-line test, the unipedal balance test (UBT), the timed up and go (TUG) test, and the 30-second chair stand test (30s CST). Health perception was evaluated by a questionnaire. Results: Repeated measures ANOVA (2×3) revealed significant improvements (p < 0.05) in TUG and 30s CST in the EG from the pre- to the post-test and when compared to the CG in the post-test. There were significant increases (p < 0.05) in health perception, 10-step test, and UBT in the EG, and significant improvements (p < 0.05) in these EG variables when compared to the CG in the post-test. Conclusions: Participating in the exercise program resulted in improvements in balance, muscle strength, agility, and health perception in the elderly of the present study.

Abstract Study aim: This study compared movement velocity and force-velocity profile parameters measured by a free video analysis software program, with the use of a high-speed video recording, and a validated linear position transducer (LPT). Material and methods: Ten team-sports athletes performed double-leg and single-leg ballistic lower limb extensions on a leg press machine against a wide range of resistive loads. Each repetition was recorded by the LPT a high-speed camera (300 fps), and later analysed with a free video analysis software program. Results: Mean and peak movement velocity presented high reliability (ICC: 0.990 and 0.988, p < 0.001) and agreement between the two measuring systems (systematic bias: –0.06 ± 0.04 and –0.01 ± 0.03 m/s, respectively). Force-velocity profile parameters were also similar: maximum velocity at zero load (Vo: 1.79 ± 0.15 vs. 1.78 ± 0.12 m/s, p = 0.64), slope (b: –1585 ± 503 vs. –1562 ± 438 N · s/m, p = 0.43), maximum force at zero velocity (Fo: 2835 ± 937 vs. 2749 ± 694 N, p = 0.41) and maximum power (1274 ± 451 vs 1214 ± 285 W, p = 0.38). Both measuring systems could similarly detect the individual force or velocity deficit (p=0.91). Conclusion: In conclusion, a free video analysis software combined with a high-speed camera was shown to be a reliable, accurate, low bias and cost-effective method in velocity-based testing.

Abstract Study aim: To investigate the interactive effects of behavioral activation or behavioral inhibition and induced pleasant or unpleasant emotions on working memory performance among young adults. Material and methods: Eighty participants (age 18–32 years) were randomly classified into 2 groups behavioral activation or inhibition and then sub-divided further via whether they received inductions in either pleasant emotions or unpleasant emotions. A pre-test measure of the working memory test was recorded and repeated after emotional induction. Results: The ANOVA analysis indicated significant effect of PERSONALITY factor (F1,76 = 4.760, p = 0.0322, ηp2 = 0.059) on results of the working memory test. The memory performance of the behavioral activation group that received positive emotion was better than the other groups, and the working memory performance of the behavioral inhibition group that received positive emotion was poorer than the other groups. Furthermore, the working memory performance of the behavioral activation group (positive emotion) was better than the other groups. Also, the working memory performance of the behavioral inhibition group (positive emotion) was poorer than the other groups. Conclusions: Finally, the findings support the different effects of the brain behavioral systems and sport emotional induction on working memory.

Abstract Study aim: In this study, it is aimed to find out the exercise preferences based on the Body Mass Index (BMI) and Body Weight Perception (BWP), and to determine the consistency between BMI and BWP calculated via the self-reporting method. Material and methods: The study was conducted total of 297 volunteers, included 174 females (Mage = 27.19 ± 9.94 years) and 123 males (Mage = 26.08 ± 10.15 years), who were members of the physical activity center. The height and body weight values were obtained based on the self-reports. BWP was assessed by asking “how do you describe your weight?” As a statistical analysis, the Pearson chi-square test and Kappa statistics were used. Results: It was determined that overweight/obese female prefered most the strength exercises, whereas, overweight/obese men, according to both methods, preferred the different kind of exercises (p < 0.05). When the mutual consistency of the BWP and BMI methods was compared, “average” level conformity was found in female, and “weak” level conformity was found in male (Female: κ = 0.48; p < 0.000; Male: κ = 0.21; p < 0.001). Conclusion: It could be said that the type and application protocol of the exercise has been related with the frequency and duration of the exercise for both of the methods. Besides, it could be said that there was a higher consistency among female participants at the level of participating to the exercise and they had similar exercise preference, frequency and duration.

Abstract Study aim: Evaluation of dynamic balance is inferred to be compulsory for fall prevention in the elderly. Therefore, this study aimed to develop a modified digital functional reach test device using an ultrasonic sensor for balance assessment and to test validity and reliability of the newly developed tool to qualify psychometric properties. Material and methods: This study was a cross-sectional study of a convenient sample including 50 participants both males and females. Mean age of the participants was 51.20 ± 19.30 years. Reliability of the newly developed device was analysed using the intraclass correlation coefficient (ICC) and standard error of measurement (SEM). The criterion validity was also investigated using a yardstick mounted on the wall at a level of shoulder together with the MaxTraq® 2D motion analysis software. The modified digital functional reach test device using an ultrasonic sensor was correlated with the conventional FRT and the MaxTraq® 2D motion analysis. Results: The results presented that test-retest reliability of the modified digital functional reach test device was good reliability (ICC = 0.76) and low standard error of measurement (1.41) was found for test-retest reliability. The degree of agreement between the modified device, the conventional FRT, and the MaxTraq® 2D motion analysis was high (r = 0.71 and 0.77 respectively). Conclusions: The findings suggested that the modified digital functional reach test device using an ultrasonic sensor was a valid and reliable instrument for fall risk screening towards functional reach distance.

Abstract Study aim: In this study, we evaluated the effects of acute and chronic exercise on the plasma FAs and their association with cardiac hypertrophy indices. Material and methods: In this pilot study, 15 sedentary and 15 athlete women underwent acute and long-term water aerobic exercise and their plasma FA levels and a number of electrocardiographic parameters, such as left ventricular end-diastolic diameter index (LVEDDI), left ventricular ejection fraction (LVEF), left ventricular mass index (LVMI), and wall thickness were evaluated before and after the exercise program. Results: The acute exercise significantly increased palmitic and oleic acid levels in non-athletes and stearic acid in both groups. However, the same type of exercise decreased linoleic acid only in non-athlete women (p < 0.05). The water aerobics training caused a significant decrease in the levels of palmitic, stearic, and arachidonic acid, SFA/UFA, and ω3/ ω6 ratios and also an increase in α-Linolenic acid and MUFA in non-athletes. We found positive and negative correlations between LVEF with ω3 and SFA/UFA ratio in both groups, respectively. In the non-athlete group, the ω3/ω6 ratio showed negative correlations with LVMI and LVEDDI. Conclusions: The study indicated that the 12-week exercise by sedentary women could make their plasma FAs composition similar to athlete women. Moreover, the plasma FA levels were associated with cardiac hypertrophy indices, showing the importance of FAs in physiological hypertrophy.

Abstract Study aim: To asses and compare the aerobic capacity and respiratory parameters in recreational basketball-engaged university students with age-matched untrained young adults. Material and methods: A total of 30 subjects were selected to took part in the study based on recreational-basketball activity level and were assigned to a basketball (BG: n = 15, age 22.86 ± 1.35 yrs., body height 185.07 ± 5.95 cm, body weight 81.21 ± 6.15 kg) and untrained group (UG: n = 15, age 22.60 ± 1.50 yrs., body height 181.53 ± 6.11 cm, body weight 76.89 ± 7.30 kg). Inspiratory vital capacity (IVC), forced expiration volume (FEV1), FEV1/IVC ratio, maximal oxygen consumption (VO2max), ventilatory threshold (VO2VT) and time to exhaustion, were measured in all subjects. Student T-test for independent Sample and Cohen’s d as the measure of the effect size were calculated.

Abstract Study aim: To evaluate the effects of providing the learners with self-controlled knowledge of performance (KP) on motor learning and self-efficacy (SE) in a dart-throwing motor task. Material and methods: The participants were thirty female university students who were divided into two groups including self-control and yoked groups. Participants performed five blocks of five trials in the acquisition phase, and retention and transfer tests of 10 trials one day later. Intra-limb coordination patterns (movement pattern), throwing scores, and SE (both movement pattern and movement outcome) were measured as dependent variables. Independent t test and one-way ANOVA with repeated measures were used as statistical tests. Results: The self-controlled group performed significantly better than yoked group on movement pattern during the acquisition phase (F1,28 = 24.239, p = 0.001) and the retention test (t28 = –3.074, p = 0.007). However, there were no significant differences between groups in terms of throwing scores and SE during the acquisition, retention, and transfer phases (all p > 0.05). Conclusion: Providing self-controlled KP can improve learning of movement pattern in the novices but do not necessary increase movement outcome or SE.
摘要:研究目的:探讨向学习者提供自我控制的表现知识(KP)对投掷飞镖动作学习和自我效能感(SE)的影响。材料与方法:研究对象为30名女大学生，分为自控组和负重组。参与者在习得阶段进行五组测试，一天后进行十组测试的保留和转移测试。肢体内协调模式(运动模式)、投掷得分和SE(运动模式和运动结果)作为因变量进行测量。统计学检验采用独立t检验和重复测量的单因素方差分析。结果:自我控制组在习得阶段的动作模式(F1,28 = 24.239, p = 0.001)和记忆保留测试(t28 = -3.074, p = 0.007)上的表现显著优于对照组。在习得期、保留期和迁移期，各组投掷得分和SE均无显著差异(p > 0.05)。结论:提供自我控制的KP可以改善新手运动模式的学习，但不一定能提高运动结果或SE。

Abstract Study aim: This study aimed to investigate the influence of combined plyometric and resistance training of lower limbs when administered for a shorter duration of six weeks on the stiffness of Achilles and patellar tendons as well as the jump height. Materials and methods: Twenty recreational athletes were administered six weeks of a single session of lower limb resistance training and one session of plyometric training every week for a total duration of six weeks. Tendon stiffness was measured using MyotonPro, and vertical jump height was derived from the force plate at baseline and six weeks after the intervention. Results: There was a statistically significant difference (p < 0.01) between the baseline and post-training measures of patellar and Achilles tendons stiffness as well as the squat jump (SJ) and countermovement jump (CMJ) height. Conclusion: Both resistance and plyometric training may be incorporated into the training session as combined training showed significant improvements in jump height and tendon stiffness after six weeks of combined RT and PT.
