DOSE RESPONSE OF PLYOMETRIC TRAINING ON AGILITY IN CRICKET PLAYERS

Aims of Study: From last one decade, advancements in formats of cricket demand agility in the players so that they can play in better way without injury. The aim of this study was to determine which dose of plyometric training is effective to enhance agility in cricket players. Methodology: Randomized Controlled Trial was registered in US clinical Trial registry (NCT04350385). 40 cricket players were recruited in study, out of which n=20 players were placed in experimental group and n=20 players were in control group. Assessments were taken as baseline and after third week and on sixth week through Illinois Agility Run test, T test and Vertical jump test. Data analysis was done through SPSS version 23. Independent t test was used for between group analysis and paired t test for within group. Results: Group comparison through T-agility and Illinois test shows significant effect in experimental group (p>0.009). Post intervention Mean±SD of vertical jump test in experimental group was 31.90±2.55 with significant effect (p=0.001). Limitation and Future Implications: This study can be done on both genders. Players can improve their performance by working on plyometric training and agility. Originality: This was original work and never published before. Conclusion: It is concluded from this study that plyometric training is effective in improving agility of the cricket players. Players can improve their performance by working on plyometric training and agility.

Some Important Aspects of General Relativity in Chern-Simon Modified Gravity

In this thesis, we investigate some important aspects of general relativity in the framework of Chern-Simons modified gravity. We focus on some dark energy models, gravitational collapse, cosmological analysis of FRW metric and consistency of the solutions. Firstly, we discuss four different dark energy models, for example, Ricci dark energy model, holographic dark energy model with Granda-Oliveros cut-off, modified holographic Ricci dark energy model and another model having higher order derivative term of the Hubble parameter by finding their scale factors and density parameters. Further, holographic dark energy model and modified holographic Ricci dark energy model are explored and the correspondence between quintessence, K-essence, tachyon and dilaton models. Secondly, we discuss gravitational collapse in the context of CS gravity by finding apparent and cosmological horizons, naked singularities, black holes and the effect of Newtonian force on the gravitational collapse. Next, we discuss the cosmological analysis of FRW universe by taking different combinations of matter, radiation and cosmological term with CS term in the dynamical background of Chern-Simons modified gravity. For all these combinations, we explore density, deceleration parameter, equation of state and stability analysis with the graphical interpretation. At the end, we find the consistency of well-known static G¨odel type solution in the context of non-dynamical Chern-Simons modified gravity and non-static spherically symmetric solutions in the presence of cosmological constant in the framework dynamical Chern-Simons modified gravity.
