It seems that aerobic exercise in water is more effective in promoting motor fitness factors due to its greater resistance force compared to the dry environment. Accordingly, the aim of this study was to compare the effect of aerobic exercise in water and land on the physical fitness of inactive girls.
Thirty non-athletic girls were randomly divided into two groups water and Land (n=15), and performed aerobic activity for six weeks (3 sessions/week) with 60-70% of maximum heart rate. Before and after aerobic activity, was calculated their explosive power using the vertical jump (Sargent), agility (4×9test), reaction (reaction time test), and the balance (static balance test). For compare pre- and post-test, and to compare post-test results in water and land, One-way ANOVA (p≤0.05).
After aerobic activity (water and land) compared to before, significant improvement was found in the values of explosive power (p=0.001), agility (p=0.001) and static balance (p=0.003), while the comparison of training in water and land did not show a significant difference (p>0.05).
It seems that aerobic activity (water and land) can affect explosive power, agility and static balance, but no effect on reaction, also there is no difference between the two environments.
