Handball is a strenuous contact Olympic team sport that places emphasis on running, jumping, sprinting, arm throwing, hitting, blocking, and pushing. It's a team sport which requires a high standard of preparation in order to complete sixteen minutes of competitive play and to achieve success. In this game, movement patterns are characterized as intermittent and change continuously in response to different offensive and defensive situations in which anthropometric characteristics and high levels of strength, muscle power, and handball throwing velocity are the most important factors that give a clear advantage for successful participation in elite levels of handball leagues 
. From this, it is believed that to improve their handball performance, elite level players must arrange specific handball conditioning with some additional resistance, as well as sprint and endurance training 
For Handball players, training aims to improve technical, tactical, psychological, and physical qualities. During the pre-season, training emphasizes on physical fitness improvements, whereas during the in-season period the emphasis is mainly on making tactical and technical improvements while maintaining physical fitness. Indeed, as competition matches require high energy expenditure, the training load is not increased in order to avoid excessive fatigue or the beginning of an overtraining syndrome 
. During a handball match, players perform different types of action such as running, jumping, and tackling. Handball players require the repetition of runs alternated with short to long periods of recovery, which could be active or passive 
. Intensity and running periods can alternate at any time according to the demands of the match. In addition, goals or decisive actions are often preceded by accelerations, sprints, bursts, jumps, and shots. Consequently, one of the aims of training is to improve the ability to perform maximal and high-intensity exercise 
. However, little is known about the best way to improve sport specific performances in handball and whether some interference between different components of physical fitness occurs when strength, sprint, endurance, sport-specific factors, and competition are trained for simultaneously during an entire season [2, 6, 7]
Sprint running contributes in varying degrees to successful performance in handball; consequently, a variety of training regimes are commonly used to improve sprinting performance, including sprint drills 
over speed training 
, sprinting against resistance 
, weight training 
, and plyometric 
. This later has been used for many years to improve sprint performance; whereas little evidence notes that this form of training improves sprint performance 
. In fact, plyometric is a type of training that develops the ability of muscles to produce force at high speeds in dynamic movements; these movements involve a stretch of the muscle immediately followed by an explosive contraction of the muscle. This pattern of muscle contraction is known as the stretch-shorten cycle. Plyometric exercises include vertical jumps, during which the athlete jumps as high as possible ‘‘on the spot,’’ and bounds, during which the athlete leaps as high and as far as possible, thus moving the body in the horizontal and vertical planes. It is generally accepted that the more specific a training exercise to a competitive movement, the greater the transfer of the training effect to performance 
. To our knowledge though, there is no information concerning the effectiveness of a combined program including repeated sprint, and vertical jump concluded by technical action with ball on sprint and jumping performances in handball.
For this reason, the main purpose of this study was to investigate the effect of a combined program including sprint repetitions and drop jump training in the same session on male handball players. The secondary purpose of the study was to investigate the effectiveness of the above-mentioned combined program on the sprinting ability of players with respect to a particular playing position.
