Abstract: Fencing competition can be studied at two time levels relative to metabolic processes to generate ATP which express particularly muscular power and muscular endurance capacity. Whereas the aerobic process allows to compete all along competition, the phosphocreatine process allows to meet the immediate demands imposed by high - intensity skills. The aim of this study is to compare the relationship between both muscular power and muscular endurance capacity in young fencers involved or not in competition. Using field tests, muscular power and muscular endurance capacity were studied in two groups of sixteen young fencers respectively involved or not in competition. Blood lactate and heart rates were measured. Because of the duration and organization of fencing competitions, fencers need both muscular power and muscular endurance capacity to face respectively high - intensity and long - term energy. However, out of a competitive context, the relationship between both muscular power and muscular endurance capacity is not crucial.

Abstract: Volleyball is a sport involving rapid and forceful movements of the body as a whole. Because of the large forces involved in such movements, it is inevitable that injuries occur. If injuries are inflicted during a game, they primarily occur in the lower extremities, and particularly in the ankles, knees, and feet, which are used for jumping and landing. Previous studies have recorded only the frequency with which various injuries occurred during matches; the type and severity of injury during training sessions were not explored. In this study, questionnaires were designed to discover the injuries that the players sustained during training for the 2014 Asian Games in Incheon, South Korea. This study aimed to identify and analyze the types and locations of frequent injuries in volleyball players during varying training phases. The results revealed that the percentage of incidences of injuries in the second session was greater than that in the first session in terms of affecting training, whereas the percentage of incidences of injuries in the first session was greater than that in the second session in terms of preventing players from playing in competitions. Furthermore, coaches should be aware of the types and location of injuries that players may sustain during various sessions of training, and accordingly advise players on how to prevent injuries before they occur. The analytical results obtained here have potential for guiding the injury-preventive measures in volleyball.

Abstract: The bandwidth knowledge of results in one way of supplying feedback during practice, which provides control over the amount and type of information given to the subject. The present study investigated the best distribution of this information throughout the practice. A task requiring to perform a sequence of movements on the keypad, in order to achieve a specific the target time. The experiment consisted of three stages: a) acquisition (50 attempts); b) transfer, ten minutes after the end of the acquisition (10 attempts); c) retention, twenty-four hours after the end of the acquisition (10 attempts). Participants were distributed into four groups: wide bandwidth, with a range of 20%; narrow bandwidth, with a range of 5%; increasing bandwidth, with a range of 5% on the first half of the acquisition and 20% on the second half; and decreasing bandwidth, with a range of 20% on the first half and 5% on the second one. The results show thin bandwidth improves performance consistency.

Abstract: The innominate malalignments are most common in sports injuries and even in every client who presents with low back & pelvis pain or dysfunction. In this study, we used simple bony palpation method to assess the various innominate malalignments in football players, which was fails to observe in previous work of various authors. While there are many methods to determine pelvic symmetry or asymmetry, this method is very simple one and that consistently works well for me. This study includes the healthy football players from National Football Club (NFC) of our institution, who were training or playing during the period of investigation (September 2014 – May 2015) (n = 40) were eligible for participation. At entry to the study, this eligible sample had a mean age of 22.2 ± 3.9 years, height of 175.8 ± 6.6 cm, and mass of 87.5 ± 7.1 kg. The number of eligible participants at each time point was 40 for all the four session time, point 1 (T1; start of preseason-3) and point 2 (T2; end of season-3). Subjects were limited to men who had a normal muscle strength and Range of Motion (ROM) of the back and lower extremities and who had no history of orthopaedic or neurologic disorders. All the individuals are subject to gain access the malalignment of both Innominate bones of the bony pelvis unit. In addition, to justify our diagnosis we access the muscles of the functional slings and the muscles around the bony pelvis. The techniques were repeated in different position and also performed for two times per day and continued for fifteen days to standardize. In this study, we observed, 92.5% i.e., the majority of the soccer's are suffering with multiple innominate malalignments. The soccer's suffering with single component malalignment account for about 25% includes the isolated Rotational, Upslip or Tilt innominate stucks and soccer's who had the normal innominate at the end of the season is only about 7.5%. Conclusion: This method of assessing the pelvic malalignments until then not documented. In this sense, the objective of this study is to analyze and document the different presentations in pelvic malalignments which are common in soccer players and its simple method of evaluation is the literature state of the art. The present study may provide useful information to analyze common presentations of pelvic malalignments in different sports.
