摘要:The objective of this meta-analysis was to observe the trends in the research in reference to the effect of water exercises on the physiology of trained and untrained population and to establish the fact about the water exercise and its responses. Articles and abstract were reviewed and presented into two sections, responses on cardio respiratory system and on the body composition. Systematic reviews on research articles from the year 1992 to 2011 were reviewed and the conclusions were drawn on both of the objectives. The finding of the meta-analysis concluded that water is one of the medium in comparison to land that helps in improvement in abilities of the cardio-respiratory system and in the reduction of body fat and body mass index because of the control experiment protocol or due to the unique characteristics of the of the water that is viscosity and bouncy.
