Abstract: Drop set training has been suggested as one of the best high intensity training techniques of all time. Though several studies have shown the effect of drop sets on limb muscles; there is a relative dearth of research on the effect of drop sets on spinal musculature. This study was aimed to determine the effect of drop sets on muscle strength and endurance of trunk extensors among trained men. Methodsː A randomized controlled trial was conducted for 6 weeks among 30 trained men recruited through convenient sampling. Participants were randomly assigned into two groups; experimental group that underwent drop sets and control group submitted to high load resistance training. A pre-test and post-test measurement of muscle strength and endurance for both groups was carried out using 1RM Strength Test and Biering-Sorensen test respectively. Data were statistically analysed by Pearson correlation and t-student tests, with a significance level of p<0.05. Resultsː At the end of the trial, significant changes are shown in pre-test and post-test scores of muscle strength (p=0.001) and endurance (p=0.003) of the trunk extensors in the drop sets training group. The findings proved that drop sets can simultaneously improve muscle strength and endurance of trunk extensors with short term training. Conclusionsː In conclusion, drop sets training achieved superior gains in muscle strength and endurance of the trunk extensors compared to high load training. In this context, this programme could potentially be used to improve trunk extensor muscle performance in trained men.

Abstract: The present study was undertaken to measure the aggression and self esteem of volleyball players of J&k State. For the study the population was all the volleyball players of Jammu and Kashmir State. For the present study, 80 volleyball players were selected randomly from Govt. degree colleges of different districts of Jammu & Kashmir. All subjects were selected with the help of purposive sampling technique .Only male sports men were selected. This was a survey study under Descriptive research. For the collection of data the researcher administered the Buss and Warren aggression Scale and Dr. Morris Rosenberg self esteem scale. The questionnaires filled up by the subjects were collected and analyzed by using the SPSS Software version 17.00. After data collection, data of aggression and self esteem of volleyball players was compared by using t-test and the result was analyzed and interpretations were drawn.
