There are different viewpoints on the effects of complex and contrast training on different components of sports performance variables. The purpose of the study was to find out the effect of complex and contrast training on selected physiological and bio-motor variables of men soccer players. Method To achieve the purpose of the study, 36 men players between the age group 18 and 25 were selected as subjects. They were divided into three equal groups (n=12). Group-1 underwent complex training; Group-2 underwent contrast training and Group-3 acted as control group which only took part in their normal playing session. The subjects were tested on selected criterion variables viz, speed, muscular endurance, cardio-respiratory endurance, blood pressure and resting pulse rate. The duration of training was 10 weeks for all the three groups. The analysis of covariance (ANCOVA) was used to find out the significant difference if any, among the experimental and control groups on the selected criterion variables separately. The level of significance was fixed at 0.05 at all levels. Sheffe's test was used as post hoc test. Results The results of the study indicate that there are significant differences among complex training group and contrast training group and the control group in all of the physiological and bio-motor variables selected for the study. Though for some of the variables, complex training group has better improvement, contrast training group has also showed significant performance in most of the physiological and bio-motor variables. Conclusions It is concluded that the complex and contrast training is beneficial for training groups that seek improvements in the selected criterion variables.
