INTRODUCTION Wilson (1969), Modern day physical education is concerned with the development of the individual to as hears the innate motor potentialities as possible. Many physical educators also consider the development of desired characteristics of individual personality structure as an important outcome of physical education. Since the degree of motor ability and extent of personality development are desired outcome of physical education, the relationship of selected factors of personality to levels of motor ability should be great importance to the profession. Physical education is that part of education which deals with big muscle activities and their related response. These activities are selected to provide an environment conducive to human and growth and development and create behavior patterns which in turn, contribute to the shaping of a better citizen .Physical education activity has the potential of playing and important role in the development and maintenance of human body and in assenting the mental., social and moral development.

Today, more than ever before, it is necessary for the physical educator and coach to recognize the vital part science plays in the successful conduct of physical education and athletic programmers. To Abstract: Purpose: The purpose of this study was to investigate effect of rope skipping, spot running, and step-ups on cardio-vascular endurance of college boys. Methods: For the purpose of this study 40 boys as subjects from V. S. S. D. P. G. College, Kanpur, were selected at random. Their age ranged from 18 to 22 years. All the subjects were randomly assigned to three experimental groups (A, B and C) and one control group (D) each consisting of 10 subjects. The experimental treatments were also assigned to the groups at random. The groups A, B and C were treated as experimental groups and were administered progressive training programme of rope skipping, spot running and step- ups respectively for six weeks. The group 'D' served as control group and continued attending the college but did not participate in any kind of training programme. Modified Harvard Step test was administered at the beginning and after the experimental period of six weeks in terms of pre-test and post-test scores on the criterion measures. To find out the effect of rope skipping, spot-running and step-ups on cardio-vascular endurance of college boys, the analysis of co-variance was used as the statistical treatment. The level of significance was set at 0.05 level. Results: The result of the study revealed there was significant effect of rope skipping, spot running, and step-ups on cardio-vascular endurance of college boys. Conclusions: In the light of the findings, it was concluded that a training of six weeks rope skipping, spot running, and step-ups was sufficient to have a significant difference in cardio vascular endurance of boys.
