the effect of tabata training and high intensity interval training toward the increasing of strength, and speed

A good physical condition is crucial to support achieving maximum performance, so proper training is needed, such as tabata training and high intensity interval training. the aims of this study are to examine and analyze the different effects of those training on increasing strength and speed.this study used a randomized group pretest and posttest design. the population in this study was male students of pko fio unesa 2016, amounting to 160 students. the sampling technique used was random sampling with a sample of 30 students. the 30 students are divided into 3 groups, namely the group of tabata training, high intensity interval training and, the control group. this type of research was a quasi-experimental, with a quantitative approach. the data were collected by measuring some techniques, such as measuring strength by using a back and leg dynamometer to measure limb muscle strength and measuring speed by using a 30-meter run. the data were analyzed by using manova technique, with α 0.05.the results showed that the effect of tabata training toward increasing strength with a value of p = 0.000, the effect tabata training toward the increasing speed with a value of p = 0.000, then the effect of high intensity interval training toward the increasing strength with a value of p = 0.000, the effect of high intensity interval training toward the increasing speed with a value of p = 0.000. based on the result of the two trainings result, it concluded that high intensity interval training is better than tabata training in increasing strength and speed.
