The effect two program work with trampoline with number of different sessions and the same volumes on some of the Physical and motor function factors in girls with mental retardation

Different training frequencies can affect the peoples’ physical fitness in different ways. The Purpose of this study was investigated the effect two programs work with trampoline with number of different sessions and the same volumes on some of the physical and motor function factors in girls with mental retardation.

30 girls student mentally retarded (8 to 16 years, weight: 37.83±1.53 kg, BMI: 19.04±4.19 kg/m2 and with an IQ of 50 to 70) were selected and randomly divided into two experimental groups and one control group. One of the experimental groups performed trampoline three times a week for 7 weeks and the second experimental group performed trampoline two times a week for 10 weeks. Before and after the training period, physical and motor fitness tests, including endurance function, Cardiorespiratory fitness, static balance, dynamic balance, agility, coordination, muscle strength and explosive Power. The data were analyzed using ANOVA repeated measurements and Bonferron's post hoc test at significance level of P<0.05.

The results showed that both exercise programs in experimental groups compared with the control group improved static balance, dynamic balance, agility, coordination, explosive power and muscle strength, but no significant difference was observed between the two training programs. Endurance function and cardiorespiratory fitness were not significantly different between the three groups.

girls mentally retarded can probably use the trampoline training with frequency of three sessions per week for seven weeks to improve their physical and motor fitness indices.
