BACKGROUND: Few studies have investigated the variations in body composition and performance in Japanese collegiate American-football players. OBJECTIVE: To clarify what characterizes competitors at the highest levels – in the top division or on the starting lineup – we compared players’ body compositions and performance test results. METHODS: This study included 172 players. Each player’s body composition and performance (one-repetition maximum bench press, one-repetition maximum back squat, and vertical jump height) were measured; power was estimated from vertical jump height and body weight. Players were compared according to status (starter vs. non-starter), position (skill vs. linemen), and division (1 vs. 2). Regression analysis was performed to determine characteristics for being a starter. RESULTS: Players in higher divisions and who were starters were stronger and had more power, greater body size, and better performance test results. Players in skill positions were relatively stronger than those in linemen positions. Vertical jump height was a significant predictor of being a starter in Division 1. CONCLUSION: Power and vertical jump may be a deciding factor for playing as a starter or in a higher division.

The aim of this study was to investigate the effects of physical activity with music on motor development and performance in children with developmental deficiencies. The study includes twenty children with developmental deficiencies, aged between 10-15 years old. Children were classified into two groups randomly and both groups were given 1 hour of training 3 days a week for 20 weeks. Physical activity with English and Spanish verbal song was used for the first group and only physical activity for the second group. Each participant participated in shuttle, shuttle run, flexibility, standing long jump, vertical jump tests.  The fatigue parameter of children was evaluated using the Visual Analog Scale. As a result of this study, it has been shown that physical activity with music is more effective method to improve motor development and performance levels of children with developmental deficiencies.

Body Mass Composition

The purpose of this investigation was to study the efficacy of two dietary supplements on measures of body mass, body composition, and performance in 42 American football players. Group CM (n = 9) received creatine monohy-drate, Group P (n = 11) received calcium pyruvate. Group COM (n = 11) received a combination of calcium pyruvate (60%) and creatine (40%), and Group PL received a placebo. Tests were performed before (Tl) and after (T2) the 5-week supplementation period, during which the subjects continued their normal training schedules. Compared to P and PL. CM and COM showed significantly greater increases for body mass, lean body mass, 1 repetition maximum (RM) bench press, combined 1 RM squat and bench press, and static vertical jump (SVJ) power output. Peak rate of force development for SVJ was significantly greater for CM compared to P and PL. Creatine and the combination supplement enhanced training adaptations associated with body mass/composition, maximum strength, and SVJ; however, pyruvate supplementation alone was ineffective.

Football Training

In this study, the effect of core training on some motor features of universıty footballers has been examined. 36 footballers both studying at Muğla Sıtkı Koçman University in Muğla, Turkey and playing in amateur leagues participated in the study. 18 university footballers of Muğla Sıtkı Koçman University Sports Club who play in Muğla Super Amateur League formed the experimental group (EG) (Age X = 21.4 ± 2.12 years, Height X = 174.3 ± 6.84 cm and Weight X = 75.9 ± 8,43 kg ). 18 footballers with amateur licences who play in the Faculty of Economics and Adiministrative Sciences, train regularly and play in the university faculty matches formed the control group (CG) (Age X = 21,6 ± 2.56 years, Height X = 176.7 ± 7.13 cm and Weight X = 76.3 ± 8.43 kg). The required permissions were obtained and the students filled in the “Admission Consent Forms” before the applications. The trainings were done in the football field of Muğla Sıtkı Koçman University and the measurements were taken in the Faculty of Sports Sciences Physiology Laboratory. The 10-movements core training programme for eight weeks was applied to the EG footballers in addition to their weekly 2-day football training when the footballers in the CG continued their regular trainings.Before the study, the leg strength, back strength, right-left hand griping strength, flexibility, and vertical jump measurement were taken as pre-test values. After the 8-week training, the final measurements of the EG and the CG were taken. The comparison between the Pretest and Posttest was studied statistically with paired sample t test at 0.05 significance levelConsequently it was determined the that the 8-week Core Training provided the undergradute footballers with an improvement of their the leg strength, back strength, right hand griping strength and vertical jump (p<0.05). No improvement in flexibility features was observed.

Grass Turf

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.
