Sixty male students aged between 17 and 22 years were selected for the study. They were divided into four equal groups, each group consisting of fifteen subjects in which Group I underwent resistance training, group II underwent endurance training, group III underwent combined training three days per week for twelve weeks and group IV acted as control, which did not participate in any training. The subjects were tested on selected criterion variables such as leg strength, back strength and cardio-respiratory endurance at prior to and immediately after the training period. For testing the leg strength and back strength, the dynamometer was used and to test the cardio-respiratory endurance, the Cooper’s 12 minutes run/walk test was administered. The analysis of covariance (ANCOVA) was used to find out the significant difference if any, between the experimental groups and control group on selected criterion variables separately. Since there were four groups involved in the present study, the Scheffé S test was used as post-hoc test. The selected criterion variables such as leg strength, back strength and cardio-respiratory endurance were improved significantly for all the training groups when compared with the control group and the leg and back strength were improved significantly for resistance training group and in cardio-respiratory endurance, the endurance training group was significantly improved. Key Words: Resistance training, endurance training, physical fitness, leg strength, back strength and cardio-respiratory endurance.

2013.) Sports training is a process of athletic improvement, which is conducted on the basis of scientific principles and which, through systematic development of mental and physical efficiency, capacity and motivation, enables the athletes to produce outstanding and record breaking athletic performances. (Dietrich Harre, 1982) While planning the dynamics of training, consider these aspects, referred to as the variables of training according to the functional and psychological characteristics of a competition. Throughout the training phases preceding a competition, define which component to emphasize and achieve the planned performance objective (Vladimir M. Zatsiorsky, 1995). Resistance training has two different meanings. A broader meaning that refers to any training that uses a resistance to the force of muscular contraction (better termed strength training), and elastic or hydraulic resistance, which refers to a specific type of resistance training that uses elastic or hydraulic tension to provide this resistance (www.wikipedia.org). Resistance training - sometimes called weight training or strength training - is a “specialized method of conditioning designed to increase muscle strength, muscle endurance and muscle power,” according to the American Sports Medicine Institute (ASMI) (Edward G. Mcfarland, www.google.com). Endurance is a term widely used in sport and can mean many different things to many different people. In sports it refers to an athlete‟s ability to sustain prolonged exercise for minutes, hours, or even days. Endurance requires the circulatory and respiratory systems to supply energy to the working muscles in order to support sustained physical activity (www.busywomenfitness.com). Leg strength plays a vital role in the daily activities of man. It is an essential factor for including in almost all games and sports. There is an old saying that an athlete will go only as long as his legs will carry him. Cardio-respiratory endurance is the ability to work close to one‟s maximum aerobic capacity for a prolonged period of time. To increase one‟s endurance is to depend Copyright © 2017, Scholarly Research Journal for Interdisciplinary Studies

upon increasing the ability to work at high, relative work load for extended periods of time. Methods In this study it was aimed to find out the effect of resistance training, endurance training and combined training on leg strength, back strength and cardio-respiratory endurance. To achieve the purpose sixty male students from various colleges around Faridabad Town, Faridabad were selected as subjects at random from the total population of 160 students. They were divided into four equal groups of fifteen each and further divided as two experimental groups and one control group, in which the group I (n=15) underwent resistance training, group II (n = 15) underwent endurance trainingm group III underwent combined training (n = 15) and group IV (n = 15) acted as control which did not participate in any special training apart from the regular curricula. For every training programme there would be a change in various structure and systems in human body. So, the researchers consulted with the experts and then selected the following variables as criterion variables: 1. Leg strength, 2. Back strength and 3. Cardio-respiratory endurance. Analysis of the Data Analysis of covariance was used to determine the differences, if any, among the adjusted post test means on selected criterion variables separately. Whenever the „F‟ ratio for adjusted post test mean was found to be significant, the Scheffé S test was applied as post-hoc test. The level of significance was fixed at .05 level of confidence to test the „F‟ ratio obtained by analysis of covariance.

Conclusions 1.
The resistance training, endurance training and combined training groups
have better improvement in leg strength after their respective training period.
But
resistance training group have better improvement in leg strength than the endurance training group and combined training group. There was no significant difference have occurred between endurance training group and combined training group on leg strength. This result is in line with findings of K. Spanos et al, (2007) and W.J. Kraemer et al (2001) who were found that there was a significant improvement in leg strength (1RM squat) after the resistance training.
Hennesay and Watson (1994) have found that
combined training (resistance and endurance training) have improved the strength significantly.. 2.
The present study shows that there was a significant improvement in
back strength after the resistance training, endurance training and combined resistance and endurance training when compared with the control group. The resistance training group have significantly improved the leg strength than the endurance training group and combined training group. Moreover, the endurance training group and combined training group didnâ€&#x;t show any significant difference on back strength. 3.
There was a significant improvement in cardio-respiratory endurance
for all the training groups. Moreover, the endurance training group and combined training group has improved their cardio-respiratory endurance efficiency when compared with the resistance training group. There was no significant difference was occurred between the resistance training group and combined training group. Raja (1992) have also found that the endurance training has improved the cardio-respiratory endurance. Reference: Tudor O.
