The Purpose of the present study was to find out the effects of circuit training and circuit weight training on Muscular strength endurance. To achieve this purpose, thirty men kabaddi players from Alagappa University College of physical education, karaikudi, were randomly selected as subjects. The age of the subjects ranged between 21 to 28 years. The selected subjects were divided into three groups of ten subjects each. The experimental group – 1(n=10 CT) underwent circuit training, the experimental group – 2 (n = 10 CWT) underwent circuit weight training and control group-3 (n= 10, CG) did not participate in any special training programme apart from their regular activities. The data was collected at prior to and after the training programme of nine weeks. Muscular strength endurance was chosen as a criterion variable. The analysis of co variance (ANCOVA) was used to analyze the data. The results of the study showed that the Muscular strength endurance was significantly improved due to the circuit and circuit weight training.

It is well established that muscle activation regulates leg stiffness to optimize stretch shortening cycle (SSC) performance. There is a significant interaction between the surface properties, muscle activation and leg stiffness. The aim of this study was to examine the potentiating adjustments after drop jumps (DJs) executed on two surfaces with different elasticity. Twenty-two adults randomly performed 3 protocols: Protocols with three pre-conditioning DJs performed on a springboard (PSB), Protocol (PG) with three pre-conditioning DJs performed on a stiff ground surface and Protocol without any type of pre-conditioning (C). Vertical jump performance was evaluated at four time points: before (COND0), immediately after pre-conditioning (COND10), and after 1 (COND60) and 2 min (COND120) of rest. Dynamics, kinematics and electromyographic parameters of the ankle were evaluated. ANOVA with repeated measures revealed statistically significant increase in Hpeak, Ppeak and Kleg was observed (p<0.05), over split-intervals and rest periods for Protocol (PSB) while no differences were recorded in jump kinematics. Both protocols (PSB and PG) significantly decreased CI during the pre-activation and eccentric phase, whereas the CI was increased during the concentric phase. The positive effect observed in jump performance could not be attributed to co-activity of the ankle joint, indicating that jumping on an elastic surface, may be beneficial in cases where increased leg stiffness is a determining factor for final performance.

The purpose of this study was to evaluate the application of a new basketball program for healthy male students at Saigon University when compared with the current basketball election classes in the physical education program. 64 healthy male students were chosen and randomly divided into two groups (experimental and control groups). All participants have experienced the 15-week training in basketball court at Saigon University every Wednesday morning. The results of the study indicated that a new basketball program had a positive improvement on speed, agility, power of leg, and maximum aerobic speed, except the core strength. Therefore, a new basketball program could facilitate greater enhancements, gave more benefits than the current program, created a healthy environment in studying physical education, and suited the enhancing training needs of male students at Saigon University. Future studies should be clarified the impact of that program for female students, for other types of sports, in line with the classification of participants, i.e., less exercise, long-term training, and high level in training of students.
