Effect of eight weeks land and sand based plyometric training on selected physical and physiological variables

The purpose of the study was to analyze the effect of eight weeks land based and sand based plyometric training on selected physical and physiological variables among inter collegiate level sportspersons pursuing their graduation under Kuvempu University. Subjects for the study were thirty (30) intercollegiate level sportspersons pursuing their graduation in Shivamogga. Their age ranged between 20 to 25 years. Purposive random sampling was observed in order to ascertain minimum levels of fitness of the sportspersons. Fifteen students each were placed randomly into plyometric training groups namely Land (N=15) and Sand (N=15) surfaces. In order to examine the efficacy of plyometric training on different surfaces following tests were conducted on all the subjects under the study. The subjects underwent these tests twice during the course of study i.e pre-test and post-test. The variables selected for the study were speed, dynamic strength, lower body explosiveness, agility, body composition and resting heart rate. Suitable standard tests were selected for assessing attributes. Paired sample ‘t’ test was used as a statistical technique apart from descriptive statistics. Within the limitations of the present investigation it is concluded that the speed aspect of physical fitness can be significantly enhanced through sand based plyometric training as compared to land based plyometric training

Yogasana and pranayama practice promotes physiological functions in male adolescents: a randomized controlled trial

Yoga has been investigated in relation to a variety of topics with focus in the reduction of symptoms of various illnesses and disorders. There has been limited research regarding yoga.s effect on physiological functions in adolescents. The purpose of the present investigation was to examine the effects of Yoga and Pranayama practice on physiological capacities of male adolescents. The Subjects for the study were adolescent boys studying between 13 to 16 years. Total 80 Subjects studying at a private school were selected through simple random sampling technique for the present investigation. 40 subjects each were placed in treatment as well as control group. All the subjects selected for this study were tested twice prior to treatment (pre-test) and at the conclusion of treatment (post-test) with a time gap of 24 weeks. Selected physiological capability parameters and testing tools were used in the present investigation. Treatment in the form of selected yogic asana along with pranayama was given to selected subjects in the specified treatment group. Twenty four weeks of training included systematic yogasana and pranayama training for six days in a week. In order to examine the hypothesis of the study paired samples t. test was used. There were significant differences in aerobic capacity and resting heart rate during pre test and post test of experimental group was 77.71and 92.89 respectively, whereas the differences in mean was not significant in control group during pre test and post test situations. In case of anaerobic capacity, systolic blood pressure and diastolic blood pressure although there were significant differences in pre and post test scores of experimental as well as control groups. On the basis of the present investigation it can be concluded that the physiological functions significantly improves in terms of aerobic capacity and heart rate in adolescent boys following yoga training
