Abstract: Authors’ Contribution: A – Study design; B – Data collection; C – Statistical analysis; D – Manuscript Preparation; E – Funds Collection. Abstract Purpose: The physical structure is considered as one of the elements for sporting success. The aim of this study was to investigate the effects of somatotype characters on selected physical performance parameters. Material: This study was included 150 males (age: 22.10±2.46 years) participants who do not have habit of regular exercise. The somatotype characters of participants were determined and physical performance tests (30 m sprint, vertical jump, anaerobic power, aerobic capacity, and flexibility) were measured as an experimental design. Results: As a result of the research, 9 different somatotype subgroups were identified. In this study, the statistically significant was found between groups in terms of explosive force, aerobic and anaerobic power output (p<0.05). We found no significant between groups in terms of flexibility (p=0.670), relative anaerobic peak (p=0.560) and mean power output (p=0.077). The results were obtained in favor of mesomorph-endomorph structure in terms of absolute peak and mean power, while mesomorph and ectomorph component contributed positively to explosive force and aerobic capacity scores. Conclusions: Our study highlighted the fact that the subgroups of somatotype have an effect on performance parameters. The body-performance relationship can be examined in detail with more participants representing each somatotype group.

The influence of low-performing students' motivation on selecting courses from the perspective of the sport education model

Abstract: Purpose: Most studies on the sport education model (SEM) have focused on curriculum content and assessed students’ learning outcomes on the basis of teaching units and items. In contrast to the SEM, direct instruction (DI) emphasizes the learning of each unit and involves a shorter learning period. Few empirical studies have explored the moderating effect of elective motivation on the relationship between the SEM and low student

Effects of electromyostimulation training on jumping and muscle strength in football players

Abstract: Purpose: Electromyostimulation is a popular training to increase muscle strength during the last years. The aim of this study was to investigate effects of electromyostimulation training on jumping and muscle strength in football players. Material: Volunteered 23 football players between the ages of 18 to 24 were divided into experimental and control groups with simple random sampling. Both groups continued to regular training. Experimental group had additional electromyostimulation training for 6-week, 3-time a week, and 20min a day. Pre- and post-training squat and countermovement jumps, peak torques of dominant and non-dominant knee extensor and flexor muscles were tested. Angular velocities of isokinetic dynamometer were 60, 180, and 300ºs-1. Pre- and post-test comparisons within the groups were analyzed. Results: There were no significant differences between pre- and post-test for isokinetic knee strength parameters at all angular velocities of EG. However, control group had significant pre- and post-test differences in dominant and non-dominant knee extension and flexion peak torque values. Conclusions: EMS and regular training in-season had no effect on the isokinetic strength parameters. On the other hand, the regular training in-season has increased isokinetic strength. Electromyostimulation training additional to regular training may have detrimental effects on outcomes of concurrent training in football players.

Comparative analysis of the athletes’ functional condition in cyclic and situational sports

Abstract: Purpose: The athletic potential of athletes depends on functional condition parameters. They determine physical and mental performance. Their evaluation is part of the athletes’ condition monitoring in many sports. The purpose of the study was the comparative analysis of the athletes’ functional condition in cyclic and situational sports. Material: The study involved 31 students from specialized sport school aged 16-17. The participants were divided into two groups depending on the sport: 1st group – 20 martial arts athletes (Greco-Roman wrestling, freestyle wrestling, judo), 2nd group – 11 water sports athletes (swimming). The level of sportsmanship was Candidates and Masters of Sports. The following tests were applied: determination of the individual minute duration (IM) (s), measuring of a 10 cm segment, (cm), and determination of simple hand-eye coordination (SHEyC), (s), and simple hand-ear coordination (SHEaC), (s), “Figures memorizing” technique, solution of 10 sums. Results: The IM test results reflect the predominance of earlier completion of the test. This tendency more expressed in martial arts athletes. The results of measuring a segment were lower in all tests in the 1st group and in 9 tests in the 2nd group. The vision reaction in 4 tests out of 10 was better in martial arts athletes. The response to the auditory stimulus in 5 tests out of 10 and the average result was better in martial arts athletes. The results of figures memorizing test were most often average. The swimmers memorize significantly fewer figures according to 3 tests. The results of the solution of sums were similar. Conclusions: The use of a battery test allows giving a comparative analysis of the functional condition of different sports athletes. The stability of IM test results indicates sufficient adaptation reserves of the participants. The analysis of the results of the measuring of segment test allows evaluating the ability to spatial orientation as an important for success quality in martial arts and water sports. The importance of the response rate for the success of both martial arts athletes and swimmers confirmed. The martial arts athletes’ results were significantly better. This confirms their ability to concentrate, to stay focused longer. The results allow considering the response rate to an auditory stimulus as an important indicator for predicting success. The figures memorizing test also reflects the specificity of sports. It illustrates the ability of athletes to control the environment, manage the situation. This ability is significantly better in martial arts athletes. The dynamics of solving sums results suggest some complexity with a long focusing on the swimmers and better parameters in martial arts athletes. The simplicity, accessibility and informative nature of the used tests suggest their use in the athletes’ functional condition monitoring.

Dynamic balance performance of professional turkish soccer players by playing position

Abstract: Background and Study Aim: Balance control has been regarded as a crucial factor in sports and indicated as an important element to be examined for the risks of injury. But it is unknown whether the dynamic balance changes according to the player positions in professional soccer players. To determine whether there were differences in the dynamic balance performance of the different positions of Turkish professional soccer players from within one squad. Material and Methods: Twenty-four professional soccer players were divided into 4 groups by the coach, including goalkeepers (n = 3), midfielders (n = 6), defenders (n = 7) and forwards (n = 8). Prior the competition season, anthropometric characteristics of players were measured. Then, players were tested Y Balance Test (YBT) for the anterior (ANT), posteromedial (PM), and posterolateral (PL) reach distances and limb lengths bilaterally. Results: The goalkeepers were heavier compared with the midfielders. Furthermore, the BMI of the goalkeepers were higher than midfielders and defenders (p< 0.05). There were no significant differences in the ANT, PM, PL, and COMP score between the groups (p> 0.05). The values for reach asymmetry were lower than four centimeters among groups in the all reach direction with regards to reach asymmetries, except normalized posterolateral direction. Conclusions: The results of this study have shown that the YBT performance scores do not differ between the groups. Future studies are required to create specific norms related to dynamic balance performance and establish risk cut-off score for professional soccer players.

Effect of long-term training adaptation on isokinetic strength in college male volleyball players

Abstract: Background and Study Aim: Most of this study focused on endurance, power, and anthropometric measurements but no research declared isokinetic strength changes during two years. The purpose of this study was to assess the effect of resistance exercises on two seasonal alters in isokinetic strength of knee muscles at different angular velocities, in college volleyball players. Material and Methods: Thirteen college volleyball players, (age: 21.75 years, body mass: 78.60 kg, and height: 187.0 cm) participated in the study. All college volleyball players take part in the two-year (8 month each year) volleyball-specific training and competitions. The measurement of peak isokinetic concentric knee extension and knee flexion torque in both legs were taken at 2 angular velocities of movement, low at 60° s-1, and intermediate at 180° s-1. Results: The pre- and post-test values of the peak isokinetic strength found that statistical significance difference, at 60° s-1 and 180° s-1 for knee extensor-flexor both dominant and non-dominant in favor of post-tests. Significant enhances were observed in the baseline dominant knee extensor-flexor muscle strength (extensor knee strength 60° s-1: 19.0%, 180° s-1: 20.5%, flexor knee strength, 60° s-1: 33.4%, 180° s-1: 31.4%) respectively. Non-dominant knee extensor-flexor muscle strength increased significantly over the two-year period (extensor knee strength 60° s-1: 21.3%, 180° s-1: 23.0%, flexor knee strength, 60° s-1: 37.4%, 180° s-1: 33.9%) respectively. Conclusion: As a result, our data suggests that the two-year planned program of specific volleyball and resistance training can increase the knee muscle extensor-flexor strength and H:Q ratios of volleyball players. Especially, at a 60° s-1 and 180° s-1 angular velocities, whilst the knee muscle extensor-flexor strength and H:Q ratios for dominant and non-dominant legs were increasing, also H:Q ratios disproportion were decreasing. Therefore, these alters indicated that regular specific-volleyball and resistance training can increase knee muscle extensor-flexor strength and H:Q ratios for dominant and non-dominant legs.

The examination of the effect of caffeine supplementation in professional soccer players

Abstract: Purpose: In this study, the effects of caffeine supplementation in professional soccer players on the Hoff and sprint tests were examined. Material: 11 professional soccer players participated in this study in line with this purpose (Xage=20.636). The Hoff and sprint tests were applied 3 times at 1 week intervals. In each of these practices, caffeine added water was performed on the participants in the first week, and placebo was performed in the second week. In the third week, the participants were tested without any additional supplement. This practice lasted 3 weeks. Caffeine supplementation was given to each participant with the amount of 6 mg / kg in 200 ml water 1 hour before the tests, and placebo supplementation in 200 ml water was given 1 hour before the tests. The soccer players did the hoff test and sprint test respectively after 20 minutes of warming period. Results: Following Wilcoxon signed-ranks analysis, it was found that caffeine supplementation and placebo applications significantly increased the hoff test averages (p <0.05), while sprint test averages were reduced significantly in statistical terms (p <0.05). Conclusions: As a conclusion, we can state that caffeine application significantly increased the hoff test averages in comparison to placebo (p <0.05), and that it caused sprint test averages to decrease significantly in statistical terms (p <0.05).

Physical performance characteristics of university male tennis players in division I and II

Abstract: Purpose: The purposes of this study were to examine the physical performance characteristics of Division-I (D-I) and Division-II (D-II) university male tennis players and to evaluate whether these characteristics could be determinative on the divisional differentiation. Material: Twenty athletes who compete in D=I (n=10) and D-II (n=10) of Turkey university tennis league (n=10) and also ranked in top-ten in their division voluntarily participated in this study. Results: Measurement of agility, upper and lower body explosive powers, fatigue index, aerobic and anaerobic powers was conducted on two non-consecutive days. Significant differences were observed in physical performance characteristics powers between the groups (p<0.05). D-I players had significantly greater anaerobic power, agility, vertical jump height, upper and lower body explosive powers, and lower fatigue index level than D-II players. However, aerobic power did not differ between groups. Conclusions: It may be possible that these results allow us to suggest that physical performance characteristics should be regarded as one of the important discriminative factors in determining the competitive level of university male tennis players.

Effect of high intensity interval training under hypoxic conditions in a normobaric environment on moderately trained university students’ antioxidant status

Abstract: Purpose: The effects of high intensity interval exercises on antioxidant defence system are not clear. Since there is an evident lack of studies focused on oxidative stress in moderately trained males following high intensity interval training, we investigated oxidative stress markers (malondialdehyde [MDA], catalase [CAT], glutathione peroxidase [GPX], superoxide dismutase [SOD]) by completing a high intensity interval training program (HIITP) under hypoxic and normoxic conditions in a normobaric environment. Material: The study was carried out on moderately trained university students who had regular exercising habits. The participants completed 8-week wingate based high intensity interval training under normoxic and hypoxic conditions (2500 m.) in the normobaric environment. They were instructed to maintain their normal dietary practices during the study not to take any antioxidant containing vitamin tablets. Results: The interaction effect (time×group) for SOD (p=0.230), CAT (p=0.736), GPX (p=0.517), and MDA (p=0.596), revealed no significant change in repeated response. Conclusions: Although 8 weeks of high-intensity interval training significantly affected only SOD and GPX (p<0.05), the normoxic and hypoxic conditions did not present any significant change between treatments.

Exercise-induced fatigue impairs visuomotor adaptability in physical education students

Abstract: Purpose: Physical exercise has been shown to exert various effects on visuomotor processing and motor learning. The present study aimed to examine the impact of exercise with progressively increased physical load on consecutive stages of perceptual-motor learning. We compared the effectiveness of visuomotor adaptability in four subsequent trials during a complex coordination task performed in different conditions, including under conditions of progressively increased physical load, and in non-exercise resting control conditions. Material: Twenty-seven physical education university students participated in this study. Participants were randomly assigned to one of two group: (1) an exercise experimental group (n = 14), or (2) a non-exercise resting control group (n = 13). Methods: Participants in the experimental group performed three 10-minute effort-tests with increasing intensity on a cycloergometer. Each participant was assigned individual workload values below the lactate threshold (40% VO2max), at the lactate threshold (60% VO2max), and above the lactate threshold (80% VO2max). Four sessions of the two-hand coordination test included in the Vienna Test System were used to examine visuomotor adaptability variation. The total time duration, total error duration, and coordination difficulty were analyzed. Results: There was a significant interaction between number of test repetitions and group (experimental, control) for total duration ( F (3,75) = 3.54, p = 0.018). In particular, there was a significant reduction ( p = 0.006) in duration in the control group after fourth test repetitions as compared to the baseline. In the experimental group, in contrast, there was a tendency for duration to increase after exercise above the lactate threshold intensity. There was also a significant interaction between test repetitions and group for total error duration ( F (3,75) = 3.14, p = 0.03). Conclusions: The results suggest that high intensity exercise can disrupt visuomotor processing during complex skill acquisition. These findings highlight the interplay between exercise intensity and motor control and learning, which in turn, has practical implications for developing and improving motor training and physical education programs.

Survey of isometric scapulothoracic muscles strength in Mazandaran University of Science and Technology athlete’s student

Abstract: Purpose: Shoulder girdle muscles are important for stabilizing the scapula and orienting the glenoid for upper-extremity motion in student athletes. Scapular strength deficits have been linked to shoulder dysfunction. Material: study the data of scapulothoracic musculature in student athletes using a handheld dynamometer. Cohort study. 66 subjects with varying levels of overhead activity. A handheld dynamometer was used to test the upper, middle, and lower trapezius, rhomboids, and serratus anterior. A one way-factor ANOVA was performed for each of the muscles by activity level analyses. 2-factor ANOVA was performed for each of the muscles by activity level and unilateral ratio by activity-level analyses. Post hoc analysis included multiple pairwise comparisons, using the Dunn-Bonferroni correction method. Results: Activity level did not significantly affect the unilateral ratios: Elevation: depression was 2.47:1, upward: downward rotation was 1.23:1, and protraction: retraction was 2.35:1. A rank order from strongest to weakest was established through significant comparisons. Conclusions: The unilateral ratios along with the rank order should be considered when discussing scapula rehabilitation protocols. Assessment of the upper and lower trapezius and serratus anterior muscles and should be part of any shoulder examination.

Based on the model of a specific athlete, the main areas of work are determined, means and methods of training effects are selected. Conclusions: Practical realization of the developed model provided the necessary increase in indicators. This made it possible for female athletes (n = 8, age 19-21 years) to improve the average result in running the main distance (compared with the previous year) by 0.18 s.

Analysis on the effects of folk dance training on players’ spatial expectation levels

Abstract: Background and Study Aim: The purpose of this study was to investigate the effects on spatial perception and spatial anticipation levels the effects of control and study groups with 16 week training folk dancing training. Material and Methods: 120 voluntary college students with no folk dancing background, 60 of which is female has participated in the study. The study group had folk dancing training of 16-week whereas control group has not done any training. Brixton Spatial Expectations test was administered to control groups at the first, eighth and sixteenth weeks of the training. Validation of which has previously been done \"Prospects Brixton Spatial Test\" has been used in the study. A statistical analysis of the data obtained was done with available statistical software (IBM SPSS Statistics 19, SPSS inc., An IBM Co., Somers, NY) and the significance level was taken as 0.05 and 0.01. Similar results were obtained between experimental and control groups in this study. Results: There were not significant differences between groups in terms of measurement time as well as in gender. As a result: Short-term training of folk dancing seems to have no impact on the level of spatial perception. Conclusions: To have a significant effect, a long-term folk dance training is required. In addition, level of spatial perception on folk dance training has no significant difference in terms of gender.
