Abstract: The purpose of the study was to find out the effect of weight jocket on Vo2 Max among college football players. To achieve this purpose of the study, thirty netball players were selected as subjects who were from the various faculties, Annamalai University, Annamalainagar. The selected subjects were aged between 19 to 24 years. They were divided into two equal groups of fifteen each, Group I underwent weight jocket training and Group II acted as control that did not participate in any special training apart from their regular sports and games practices. The subjects were tested on selected criterion variable such as Vo2 max prior to any immediately after the training period. The selected criterion variable such as Vo2 max was determined through using Treadmill. The analysis of covariance (ANCOVA) was used to find out the significant differences if any, between the experimental group and control group on selected criterion variable. The 0.05 level of confidence was fixed to test the significance, which was considered as an appropriate. The result of the present study has revealed that there was a significant difference among the experimental and control group on Vo2 max.

Abstract: The aim of the paper/study was to investigate categories, causes and consequences of risks in sports identified by Sports administrators in State Sports Councils, South East, Nigeria. In order to achieve the research objectives, three research questions guided the study. The study adopted descriptive survey research design and use one hundred and fifty-five sports administrators (Directors of sports, organizing secretaries and coaches) as population and sample for the study. Structured and validated questionnaire was used for data collection and all statistical analysis was done using Statistical Package for Social Sciences (SPSS) version 21. Hundred and thirty-five copies of the questionnaire were used for data analysis because other copies suffered mortality. Mean scores were used to answer the research questions using 2.50 as the criterion mean. From the results, risk of injury, risks of financial loss and risk of damaging sports facilities were identified by the sports administrators as risks in sports with risk of injury as the most occurred risk. Also, the sports administrators identified the cause and consequences they encounter in their various sports councils depending on the category of risk. The study concluded that sports administrators in State Sports Councils, South East, Nigeria, know the pertinent risks they encounter as they discharge their duties and cause and effects of such risks.

Abstract: The present study examined the associations and age-related development of motivational climate, achievement goals, enjoyment, technical skills, and body mass index (BMI) in young floorball players. The sample comprised 283 Finnish competitive male floorball players with a mean age of 11.49 ± .27 years in the beginning of the data collection. Players completed floorball-specific technical skill tests and questionnaires across two time points, twelve months apart. The path model showed that perceptions of task-involving climate positively associated with mastery-approach, performance-approach, and enjoyment, whereas perceptions of ego-involving climate related with mastery- and performance-approach and mastery- and performance-avoidance. The results indicated that players with higher BMI had higher mastery-avoidance and slower dribbling skill scores. However, the findings supported previous findings, as a player can have high mastery-approach and high performance-approach or high performance-avoidance at the same time. Finally, mastery- and performance-approach, performance-avoidance, dribbling skills, and passing test scores increased over time. In contrast, perceptions of task- and ego-involving climate, mastery-avoidance, enjoyment, and BMI remained stable. The findings indicated that task-involving coaching methods could enhance approach goals and enjoyment in young floorball players. All young floorball players, especially players with higher BMI could benefit, if they were encouraged to spend more time with a wide range of fundamental skill practices on their leisure time, not only during the organized sessions. This could increase their floorball-specific skills, and in turn, decline the negative perceptions of mastery-avoidance.

Abstract: This study aims at examining the dietary intake status of adolescent swimmers. It also compares nutrient intake against the recommended dietary allowances and its associated implications on athlete’s health. A total of 65 subjects aged between 11 to 18 years was purposively selected; 35 swimmers and 30 non-swimmers. A structured Food Frequency Questionnaire was used to collect data. Correlations between continuous variables, association between BMI of swimmers and non-swimmers were calculated using ANOVA. The χ² test was used to compare the nutrient intake with the RDA of control and experimental group. Swimmers were taller, heavier and had higher waist hip ratio to a non-swimmers. The experimental and control groups reported a significant BMI and MAC. Females in two groups consumed meat protein than their male counterparts despite that the groups had many non-vegans. Although not statistically significant, men's consumption of food stuffs was higher than women; with χ² reflecting 3.4897 and 6.4371 respectively at 5%. Comparing MAR and NAR from swimmers and non-swimmers, nutritional intake in both swimmers and swimmers were seen to be inadequate in calcium (93%; 97%), riboflavin (91.7%; 92.6%), zinc (71%; 78.5%), and absorbic acid (94.2%; 95.7%) whereas intake of iron (0.4%; 1.1%) and protein (8.3%; 12.2%) was found adequate except for few swimmers. The means for groups were 0.71 and 0.75 respectively indicating that one or more nutrients were lower than the RDA. Despite that most energy intakes from the subjects were higher than RDA, mean of male and female swimmers on total fibre and fat were below the recommended daily allowances though significantly statistical at 5% level as 2.2645 and 2.1732 respectively. Adolescents showed that they were not consuming less water compared to other drinks of water even after training sessions. A healthy diet throughout is important to provide nutrients that support optimal physical growth and cognitive development.

Abstract: The Purpose of the study was to EMG Analysis of Chest and Back Muscles and their Correlation with the Performance of Jump Tennis Service in Volleyball. Coverage/ Selection of Subjects: Universe of the Study: The study was confined to India only. Sampling Frame: Subjects were selected as a sampling frame from India only and their age was ranging from 16 to 28 years. Sampling Methods: Subjects were selected on the basis of purposively random sampling method. Sampling Size: A total of 12 male professional Volleyball players from India were selected for the study. Units of Observation: Observations were made on the following Variables/contents: Pectoralis Major (PMJ), & Trapezius (TP). Criterion Measures: Muscles activities during jump tennis service in volleyball were measured by Neuro Trac Myo Plus 4. The data was recorded in micro volt (µv). Statistical Techniques: The concerned data was analyzed by using descriptive statistical in order to electromyographic analyses of chest & back muscles during executing the jump tennis service in volleyball. In order to determine the relationship of selected (chest & back) muscles activities with the performance of jump tennis service in volleyball, Pearson Multiple Correlation Technique was used. The level of significance for the entire analysis was set at the 0.05 level. Conclusions: According to finding the study, Trapezius muscle showed the highest activation level of EMG during execution of jump tennis servive in Volleyball. Pectoralis muscles showed the 5th highest activation level of EMG during execution of jump tennis service in Volleyball. Only one muscles group that is Pectoralis is found correlated with the performance of jump tennis service in Volleyball. The insignificant relationship was found between back (Trapezius) muscles and with the performance of jump tennis service in Volleybali.
