The aim of this study is to examine the effect of soccer training on natural turfs on strength, speed, power and balance characteristics in prepubertal children. Twenty-two male athletes chosen from the 12-13 age group who play soccer in the youth team of an amateur soccer club from Istanbul, Turkey volunteered to participate in our study. In the study, 30 m sprint, Y-balance, standing long jump and vertical jump tests were done as pre- and post-tests. The same training program was assigned to the players, who were separated into two groups. One group was trained on synthetic grass turf (SG) while the other group was trained on natural grass turf (NG) for eight weeks. As a result of the statistical analyses, significant improvements were observed in all parameters between pre-and post-test measurements of both SG and NG groups (p<0.05). When the developmental differences of the groups were examined, statistical improvement was found in the standing long jump parameter in favor of the group that trained on Natural Grass turf (p=0.037). In conclusion, depending on the characteristics of the soccer game, enhancements were observed on both surfaces. However, the challenge effect of natural grass turf was more effective than that of synthetic grass turf on leg strength improvement. It is considered that as a result of continuing their soccer trainings on natural grass turfs, young players can improve their performance and can avoid possible injuries.

PURPOSE: This study aimed to compare the effects of low-volume and high-volume sled-push resistance training on muscle strength, power, and body composition.METHODS: Twenty-four college students were recruited and matched based on baseline one-repetition maximum (1-RM) into one of the three groups: 1) low volume (LV) resistance training, 2) high volume (HV) resistance training, or 3) control (CON) (n=8 per group). The LV training consisted of five single repetitions of pushing a weighted sled for 9.1 m. The HV training consisted of three sets of five repetitions of pushing a weighted sled for 9.1 m. Training consisted of three weekly workouts performed on nonconsecutive days for 6 weeks. This study utilized a pre-test and post-test design consisting of 1-RM, Wingate power test, standing long jump, vertical jump, and body composition.RESULTS: After 6 weeks of training, there was a similar but significant increase in 1-RM in both training groups (pre-test: LV=226.8±14.8 kg vs. HV=217.7±19.5 kg; post-test: LV=298.5±15 kg vs. HV=286.9±16 kg, <i>p</i><.001). However, no improvements were observed in the Wingate power test, standing long jump, vertical jump, or body composition in both training and CON groups (<i>p</i>>.05).CONCLUSIONS: The results suggested that low-volume resistance training was as effective as a high-volume protocol for improving muscle strength. However, the present study was unable to determine the effects on muscle power and body composition.

<p class="apa">The aim of this study was to examine muscle strength and flexibility of Judoka with and without visual impairments. A total of 32 male national judoka volunteered to participate in this study. There were 20 male judoka without visual impairments (mean±SD; age: 19.20±5.76 years, body weight: 66.45±11.09 kg, height: 169.60±7.98 cm, sport age: 6.20±1.15 years). There were 12 male judoka with visual impairments (mean±SD; age: 24.50±4.06 years, body weight: 75.58±22.49 kg, height: 173.50±7.23 cm, sport age: 8.08±1.44years). Judoka were also assessed on several strength measurements including standing long jump, right hand grip, left hand grip, vertical jump, leg strength, sit-up and push up, and flexibility with sit and reach. We found significant differences between with and without visual impairments in leg strength, left and right hand grip and push-up (p&lt;0.05). On the other hand, there was no significant difference between with visual and without impairments in vertical jump, sit-up, flexibility, and standing long jump (p&gt;0.05). In conclusion, it is considered that visual impairment issue does not have negative effects on physical development and muscle power performance levels for ones doing judo sport because elite active athletes’ training levels are close to each other.</p>

<p class="apa">The purpose of this study was to determine the effect of core training program on speed, acceleration, vertical jump, and standing long jump in female soccer players. A total of 40 female soccer players volunteered to participate in this study. They were divided randomly into 1 of 2 groups: core training group (CTG; n = 20) and control group (CG; n = 20). The mean (SD) age was 19.05 ± 1.15 years, height was 160.60 ± 4.22 cm, weight was 56.45 ± 3.33 kg, and sport age was 4.50 ± 1.24 for the core training group; the mean (SD) age was 18.55 ± 0.76 years, height was 159.10 ± 3.86 cm, weight was 52.20 ± 3.60 kg, and sport age was 3.35 ± 0.75 years for the control group. Following randomization, the 2 groups did not differ significantly (p&gt;0.05) in any of the dependent variables. The subjects in the control group did not participate in the training and participated only in the pre- and posttest measurements. To evaluate the effect of core training over the functional performance, we applied a testing procedure that included measurements of speed, acceleration, vertical jump, and standing long jump. The core training group showed a 3.4%, 5.9%, 13.3%, 4.2% improvement in speed, acceleration, vertical jump, and standing long jump (respectively) (P&lt;0.05), whereas the control group did not change (P&gt;0.05). In conclusion, Core exercises were improved speed, acceleration, vertical jump, and standing long jump in 18-19 years-old female soccer players. Therefore, it is believed core training is necessary for optimal sport performance and should not be dismissed for all sport branches.</p>

The purpose of this study was to examine the effects of speed training on sprint step kinematics and performance in male sprinters. Two groups of seven elite (best 100-m time: 10.37 ± 0.04 s) and seven sub-elite (best 100-m time: 10.71 ± 0.15 s) sprinters were recruited. Sprint performance was assessed in the 20 m (flying start), 40 m (standing start), and 60 m (starting block start). Step kinematics were extracted from the first nine running steps of the 20-m sprint using the Opto-Jump–Microgate system. Explosive power was quantified by performing the CMJ, standing long jump, standing triple jump, and standing five jumps. Significant post-test improvements (p < 0.05) were observed in both groups of sprinters. Performance improved by 0.11 s (elite) and 0.06 s (sub-elite) in the 20-m flying start and by 0.06 s (elite) and 0.08 s (sub-elite) in the 60-m start block start. Strong post-test correlations were observed between 60-m block start performance and standing five jumps (SFJ) in the elite group and between 20-m flying start and 40-m standing start performance and standing long jump (SLJ) and standing triple jump (STJ) in the sub-elite group. Speed training (ST) shows potential in the reduction of step variability and as an effective short-term intervention program in the improvement of sprint performance.

The aim was to find out, compare and evaluate the eficiency of take-off preparation for selected indicators of motor performance in athletes in the category of younger pupils. The monitored group consisted of 5 girls (average age 12.4 ± 0.22 year) and 4 boys (average age 12.9 ± 0.12 year) regularly participating in the training process three times a week. During 8 weeks in the racing period, take-off preparation was applied in the training pro-cess, consisting of two different batteries of take-off drills. The take-off preparation took place two to three times a week, taking into account the participation of athletes in the race. We performed the following tests to determine the eficiency of the take-off preparation to change the level of motor performance in selected indicators: 50m run, 20m cursory run, standing long jump, vertical jump with countermovement without arm swing and repeated vertical take-off drills without arm swing in 10s. We found that in the output measurement, the athletes of monitored group achieved an improvement in motor performance in tests for explosive power of lower limbs and the maximum running speed tests.

The aim of this study was to determine the relation between some motoric and physiological characteristics of 13-15-year-old female volleyball players regarding their positions on the field. A total of 120 volleyball players have participated voluntarily. 30 of the participants whose mean age value was 14±0,76 were setters; 30 of them were liberoes with mean age value of 13,8±0,45; 30 of them were middle blockers with the mean age value of 14±0,79; 30 of them were hitters with mean age value of 13.52±0,68. The age, height, body weight, right-left hand gripping strength, vertical jump, throwing medicine ball, standing long jump, 30-second speed and body fat percentage measurements of the volleyball players have been performed. In evaluating the data, the One Way ANOVA has been used. No statistically significant differences have been determined between the age, weight right hand gripping strength and body fat percentage measurement results concerning the positions of the volleyball players, who participated in the study (p>0.05). On the other hand, it has been identified that there is a difference between the height, left hand gripping strength, throwing medicine ball, standing long jump, and speed values in terms of their positions (p<0.05). The results of the study could be beneficial to evaluate the motoric and physiological characteristics of the volleyball players regarding their positions in establishing teams and in preparing training programs.
