STUDY ON THE EFFECTS OF AQUATIC VS. DRY LAND COMBINED CONTRACTIONS ON MUSCLE STRENGTH FOR THE STUDENTS IN PHYSICAL EDUCATION AND SPORT

Researchers in our country have examined only the dry land effects of combined contractions on muscle strength. Thus, there was conducted a study during an academic year (October 2008 - May 2009), whichaimed to develop and experiment some training programs through schemes of aquatic and dry land combined contractions, and test of 5 power indicators on 24 students - boys second year in the Faculty of Physical Education and Sport of Pitesti, aged 18-20 years who were selected voluntarily and divided into two experimental groups (aquatic n = 12 experimental group and dry land n = 12 control group) to compare the results of muscle strength development. The same training, testing facilities and methods were used for eachassessment and lesson. Each lesson took between 65-70 minutes, three days a week. Tests were performed using Quatro Jump Kistler platform, Bosco Protocol Version 1.0.9.2., and provided information about both jump height and power and data on neuro-motor ability (fast fibers), volunteer effort, fatigue, the stretching effect or muscle elasticity. The results of the experiment showed that the experimental group improved their power indices compared with control group, which used the same dry land-adapted programs, with a value between: 2.47 and 8.47%.
