Aim of this study was to find out the Effects of Circuit Training and Yogic Practices on Power Production. The study was conducted on sixty men college students from various arts and science Colleges in Thanjavur District were randomly selected as subjects. They were randomly assigned equally into three groups, Group –I underwent Circuit Training Group (n = 20), Group II underwent Yogic Practices Group (n=20) and Group-III acted as control Group (n=20). Among the power parameters leg explosive strength was selected as creation variables. Leg Explosive power was measure through sergeant board. The data was collected from the Experimental and Control Groups were statically examined with Analysis of covariance (ANCOVA). Leg Explosive power showed significant difference among the groups.

The purpose of this study was to investigate and compare, on a set of basic anthropometric characteristics, specific volleyball performance indicators and a number of haematological parameters, between elite and non-elite female volleyball players in India. A total of 39 subjects were assesses and analysed for three sets of indicators: 5 anthropometric characteristics (BH, BW, BMI, %BF, and %LBM), 3 performance tests (Jump with one hand, Jump with two hands, Height of the Arm) .The obtained results show that physical parameters such as body height, height of the arm, body weight, %BF display generally better values in elite teams but special abilities could be found and appreciated also in a local team, although with less better starting anthropometric and physical characteristics. The physical parameters are collinearly correlated to jump performance tests in both teams but with better values in the local team, different from the expectations. The above parameters, alone and in combination with each other, would allow coaches and athletes to identify and assess the physical and performance characteristics specific to the age groups for purposes of professional evaluation, selection, monitoring and continuous development at both individual and team level.

The study of individual and group behavior within the sporting context has been a varied and helpful attempt. In studying behavior, the sport context allows for a somewhat structured and controlled setting without the need of a laboratory. In attempts to explain and predict phenomena in sport, a popular area of research for the study of both athletes and coaches has been focused on various personal attributes. One attribute that has been found in many settings to influence behavior is self-efficacy. It will be helpful to understand for coaches the importance of sport coaching and self-efficacy in sport. This empirical review literature argue self-efficacy theory, measurement of selfefficacy, research on athletes, teams and coaches and collective efficacy research on sport.

The purpose of this study was to compare the aggression and mental toughness among players of armed force sportspersons and civilian sports persons. Sports Aggression Inventory by P.S. Shukla was used to gather data about the aggression and Mental toughness Questionnaire prepared by Dr. Alan Goldberg was used to gather data about Mental toughness of sports persons from different groups. The test was conducted on 70 male of armed force sports person and civilian sportsman. Data were undergone to t test for analysis purpose at 0.05 level. The test was conducted on 70 male of armed force sports person and civilian sportsman. The result shows that there is no significant difference in mental toughness and aggression among armed force sportsmen and civilian sportsmen.

The objective of the study was to find out the effects of Plyometric Training and Resistance Training on Agility of Basketball Players. For the purpose of the study 60 male basketball players of West Bengal who had participated in various tournaments in basketball at the national, inter-varsity, or state level were selected. Their age ranged from 18-23 years. Agility was selected as a dependent variable and plyometric training and resistance Training was considered as Independent Variables. For the study pre test-post test randomized group design comprising of two experimental groups (n=20 in each group) namely plyometric training group (PT) and resistance training group (RT) and one active control group (n=20) were adopted. To test the Agility of basketball players, Illinois Agility Test was used. To compare the effects of plyometric training and resistance training on agility of basketball players, Analysis of co-variance (ANCOVA) was used. The level of significance was set at 0.05. The result reveals that there was significant effect of the plyometric training programme on agility of basketball players but no significant effect was found by resistance training programme. Based on the findings and within the limitation of the study it was noticed that plyometric training help to improve agility of basketball players since the agility performance of the subjects of experimental groups were found statistically significant.
