The aim of this study was to verify the impact of two specific training programs, strength training and plyometric and its impact in improving the economy to running and explosiveness in handball. In this regard, 12 adult subjects were invited to participate in the study. They were randomly divided into two groups of 6 players. The first group was stripped of plyometrics training; the second group underwent training on conventional fitness machines. Each group has been training 4 times a week for two hours per session for a period of 12 weeks. To determine the effect of each of the two training conditions, we measured the VO2 at 90% of the VMA, on a treadmill for 4 minutes and took the volume of oxygen consumed during the last minute as reference to the economy to the running. The explosiveness was measured by two vertical jump tests, SJ and CMJ using myotest. The variables presented are the jump height in cm, the velocity in cm / s, the power in w / kg and strength in N / kg. Also we measured movement speed by sprinting test on 10 and 20 meters. The quality of high-intensity intermittent running was measured by intermittent yoyo test 2 (YYIRT2). The results show a significant difference between the two groups (PRE vs. POST), and also between the two groups (POST Plyometrics vs POST strength training).

The Effect of Two Training Methods: the Plyometric and the Strength Training, on the Economy to the Running and Explosiveness in Handball
