Boxing is a polystructural acyclic sport and a very complex activity that requires versatility, maximum mastery of punching techniques, movement and stances. A high level of technical – tactical abilities and physical – psychological preparation is necessary for boxers. Explosive and dynamic movements prevail, which is why a high level of coordination is required. The demands and activities within each round are of high intensity, therefore glycolytic energy processes dominate. Considering the duration of the fight, the development of aerobic abilities is also necessary, due to recovery between rounds or delaying fatigue. In boxing, we recognize three main types of punches: jab/cross, uppercut and hook, and an ideal punch consists of good coordination and synchronization of the whole body, from the legs, through the torso, and finally to the punching hand. In order to generate as much force as possible with a punch, and even more importantly to transmit that force in the shortest possible time, training with resistance, in other words power and strength training, is necessary. Power represents overcoming force in the shortest possible time, and strength represents the maximum force that an athlete can produce. With the specific preparation of boxers, it is necessary to pay attention to exercises that include the entire locomotor system. In order to fully utilize the adaptational potential of the muscular and nervous system and to optimally develop power and strength in boxers, it is necessary to use different power and strength training methods.
