Grappling, a martial art based on techniques of gripping, throwing, controlling, and forcing an opponent to submit, has a long history in various cultures worldwide. Grappling is categorized among polystructural acyclic sports. The combat takes place in acyclic and dynamic conditions, and the outcome can be victory or defeat. The conflict with the opponent is direct, and the goal is the symbolic neutralization of the opponent. Movements include stances, motions, grips, falling techniques, locks, chokes, throws, and holding techniques. Factors that influence success in grappling are strength, power, speed, coordination, flexibility, and balance. Anaerobic endurance is the most significant due to the specifics of the fight, while the aerobic phase occurs in the breaks between bouts. Training should be conducted in specific conditions, i.e., sparring. Flexibility is crucial in ground fighting due to positional changes, while stability and balance play a role when passing the guard. Grappling activates all major muscle groups, requiring strength in various types of contractions. Strength training must be conducted without excessive muscle hypertrophy due to weight categories. In wrestling, speed and agility are often decisive factors. Quick reactions, escape agility, and skill in takedowns are crucial for success. Wrestlers must regularly include specific agility exercises in their program. Speed training plays a key role in a wrestler's overall performance and is closely related to other important aspects of training.
