A large amount of research has been conducted since 1950's concerning the proper warm-up regimens and recommendations for recreational and professional athletes before the training programs and the pre-event warm-up activities.Given that a warm-up can undoubtedly be advantageous in muscle damage prevention and performance enhancement, taking into consideration recent knowledge growth and new theories development, there is much debate between specialists, regarding the type of warmup methods choice and its relevant characteristics manipulation, in order to prepare athletes for training or competition [1].Although the practice of some of the recommended warm-up components is widely undertaken, the value of warm-up is usually based on the trial and error experience of the athlete or coach, only few studies have investigated the warm-up related physiological changes in actual training or competition.Summarizing the findings of the many warm-up studies conducted over the years is difficult [2]. Practically, several studies advocate that the warm up for power activities should include both general and specific activities [3], including stretching exercises as a part of general warm-up routine, as well as dynamic-ballistic exercises that mimic the main activity at progressively higher intensities in an attempt to increase neuromuscular activation. The purpose is obviously to prepare players for the game or training.However, a number of practical questions rise concerning a) the necessity of static stretching in order to achieve the goals of injury prevention and performance enhancement, b) the relation and the order of using static and ballistic stretching to impair physical performance, c) the scientific base and the agreement between specialists to pick up the method they feel is best suited to the sport and the athletes.Static stretching is the most frequently used technique to increase flexibility, because it seems to be more easily executed and safer than others [4]. However, many authors reported that the use of static stretching before maximal physical activity may temporarily reduce force and power production [5][6][7], vertical jump performance [8][9][10] and running speed [11,12]. In contrast, other studies have observed no detrimental effects of static stretching in selected neuromuscular parameters [13][14][15][16]. A number of mechanisms have been proposed to explain stretching decreases in force and power performance as: a) the low levels of musculotendinous stiffness [17], b) the reduced ability to recruit motor units [18], and c) the inhibition of the acute response of muscle proprioceptors, such as the Golgi tendon organs [19].Therefore, some researchers tend to be against the use of static stretching before activities that require high levels of strength and power [5,[20][21][22].On the other hand, a number of studies have reported that ballistic stretching, which consists of fast specific movements that usually mimics specific sport kinetic patterns [23] can improve power production [11,24,25].
