Abstract

This paper deals effect of freeletics and High Intensity Interval Training (HIIT) exercises on cardiovascular, strength, and speed. Subjects used 31 male futsal players at sub elite. Data analysis used mean, standart deviation,  t-test (paired sample t-test) and manova (multivariate analysis of varians). The results clear show that three finding principal difference between pretest and posttest mean of each group were: (1) experiment group I freeletics for cardiovascular = 1.77 ml/kg/min, strength= 14.36 kg, and speed = -0.25 second. (2) Experiment group II HIIT for cardiovascular = 1.82 ml/kg/min, strength = 10.85 kg, and speed = -0.30 second. (3) Control group for cardiovascular = 0.4 ml/kg/min, strength= 2.75 kg, and speed = -0.07 second. Concluded this paper significant exercise of  freeletics strongly effect on the increase in muscle strength and performance. While exercise of HIIT strongly effect on the increase in cardiovascular and speed. Implication of this study can be used to evaluate the training program in order to improve performance enhancement of the players.
