A Survey on the effects of a Selected 70 Percent of Maximum Running in Shallow Water on 15-17 aged High School Girlʹs Aerobic Power and Body Composition

Water aerobic training perfermed in different forms such as runing, (jumping and walking, has its own unique effects. Running in shallow water, is accomplish in three different forms: running in shallow water, running with special floating devices in deep water, and running without any floating devices in deep water jumping, and walking, has its own unique effects. In this study, aerobic power, body composition, weight, and 540 m run time are determined as pretest and post test in 22 untrained high school girls (mean age 15.42 ± .82), divided in two experimental and control groups(n =11). Experimental group began their training program in water as high as 70 percent of their heights, and continued this for 3 days a week for 18 bouts. Running times in waterʹhas began from 20 min, increased 1 min per session, so that finally subjects bran about 37 min.Mean temperature of water during entire training was 27 -±- 2°C. The following results has obtained finally: 1. 4.7 percent significant increase in absolute Vol max. 2. 1.7 percent significant decrease in weight . 3. 6.5 percent significant decrease in percent body fat. 4. 12.8 percent significant decrease in 540m run time In summary, with respect to the results of different studies in this field, the objectives of aerobic water training, determine. Training form and quality: if the objectives of training are maintaining cardiovascular fitness of injured athletes or special population, then it would better that training be performed in deep part of the pool, with or without floating devices. If the objectives of training are Vozmax improvements, then it would better that training be performed in the shallow part of the pool, main taming running pattern in track.
