Reliability and validity of mobile application for hamstring muscle power among Military Cadet

Mobile learning using information technology elements is facilitating, helping the learning outcomes of a learning process more quickly and effectively especially in physical fitness. The aim of this study is to develop and measure the reliability of mobile application for standing broad jump test physical fitness among Army Cadet Officers of National Defense University of Malaysia (NDUM). This is a quantitative research using the test-retest method to obtain the reliability value by using mobile application as research instrument. The standing broad jump physical fitness test battery is use to develop mobile application and to measure the reliability of mobile application on the subject fitness. The findings showed the correlation coefficient between the first test score of the use of mobile application for standing broad jump and the second test score of the use of mobile application for standing broad jump are significant (r = 0.92, n = 30, p <0.001). The results of the study found that the value of Pearson correlation coefficient for both tests was r = 0.92. This shows the reliability of the use of mobile applications for standing broad jump test is high and acceptable. The implication of this study, the mobile application used is easy to obtain results on the level of physical fitness of muscle power for NDUM cadet officers. Not only that, this mobile application only requires a mobile phone, which is owned by all communities, and it is easy to be
implemented anywhere.
