The purpose of the study was to determine if there are differences in gender and circadian rhythm that affect the flexibility of volleyball players. Thirty volleyball players (15 men and 15 women) between 19 and 22 years of age were randomly selected as subjects. The two independent variables of gender and circadian rhythm and the dependent variable of flexibility were evaluated. The experimental design used was a static group factorial design. The flexibility data were collected by using sit and reach test at 02:00, 06:00, 10:00, 14:00, 18:00 and 22:00 hours during the academic year of 2012-2013. The data were statistically analyzed using a two-way factorial (2 x 6) Analysis of Variance (ANOVA) and Cosinor analysis. There was a significant difference between genders, significant difference in different times of the day and significant circadian rhythmicity exists on flexibility. The study concluded that the variation in flexibility at different times of the day would have a large effect on the performance of volleyball players. It is recommended to the physical educators to adopt the findings of this study while planning to improve sports skills for the players and athletes.

Sports are psychological and physical because it is led by psychology and performed by physique. There is a good head and muscle or psyche and body coordination in sports for achieving success in competition. The head, the thought images and mental pattern play significant role in sports performance.

The normal physical and health conditions of Indian people and that in rural or urban areas are dangerous. During each age and stage different kinds of unknown diseases and health problems caused a large damage to the Indian human society. The occurrence and the frequency in occurrence of the helminthic diseases date back beyond the dawn of history.

A single-subject/qualitative design was employed to determine if mental training program improved athlete's performance in track & field events as well as a variety of mental skills such as Imagery ability, Mental Preparation ability, Self Confidence, Anxiety Management, Concentration ability, Relaxation ability. Four male participants (age 18 – 24) participated in the study. To measure mental skills, all the athletes completed Hardy and Nelson's mental skills Questionnaire both during baseline and intervention period. Nine performance trials for each athlete were taken including baseline and intervention. Results of visual inspection of multiple baseline graphs suggested an increase in track & field performance for all the athletes. There was also an increase in all the mental skills for all the athletes except participant 3 and participant 4 had a decrease in concentration ability whereas self confidence for participant 3 was constant.

Self concept is a multidimensional construct that refers to an individual's perception of self in relation to any number of characteristics, such as academics, gender roles, racial identity etc. The self concept is an internal model which comprises self assessments. Anxiety is a psychological and physiological state characterized by somatic, emotional, cognitive and behavioral components. Anxiety invokes a feeling of fear or a perception of threat and which may be specific to and particular situation.The Purpose of the the present study to find out the Self concept and anxiety among Sprinters and Jumpers of Osmania University,Hyderabad.The sample for the present study is fifty Male Sprinters and fifty Male Jumpers those who have participated in the Osmania University Inter College Athletics Championships during the year 2012-13. R.K.Saraswath Self Concept Questionnaire and Sinha's Comprehensive Anxiety Test are used in the study. Each of the two instruments were administered individuals as well as a small group. Prior to administration of test through informal talk was explained the subjects procedures of the tests.This study shows that Sprinters are having high self concept and low anxiety compare to Jumpers.It is concluded that that Sprinters are having the good self concept and less anxiety to achieve the high level of performance

Body Mass Index is an easily accessible and viable tool for assessing obesity. This study investigated the difference in Body mass index (BMI) between Private and Government school children. A total of 265 school children (age 12-13) were selected for the study out of which 145 were from private schools and 120 were from government schools. Body Mass Index (BMI) was calculated by dividing weight in kilograms by height in meters squared for all the students. Independent t test shown that private school students BMI (25.28+2.09) is significantly higher than Government school students BMI (17.47+3.81).
