The purpose of this study was to compare National Gymnastics(A), Gymnastics for Adolescents(B), Basic Gymnastics for the
New Millenium(C) and Easy Gymnastics for the New Millenium(D) in objective exercise intensity and energy consumption, as well
as to estimate the exercise effects of each gymnastics. The subjects were young adult women(n=10) in their twenties. An
exercise stress test was conducted to obtain maximum heart rates, VO2max and the K4b2 was used to obtain all the values when
each of the gymnastics were performed. As a result, the energy consumption(cal) and energy consumption per weight(cal/kg)
were in the order of C>B>D>A(p<.001), and the energy consumption per minute(cal/min) and energy consumption per weight and
minute(cal/kg/min) were in the order of B>C>D>A(p<.001). In addition, exercise intensity was recorded the highest level in B and
C, the intermediate level in D and the lowest level in A(p<.001). In short, Gymnastics for Adolescents and Basic Gymnastics for
the New Millenium with significantly higher energy consumption and exercise intensity seem to be proper for adolescents and
healthy adults. National Gymnastics has only a little value as an exercise thus it is difficult to be recommended, and Easy
Gymnastics for the New Millenium seems to be appropriate for the elderly.
