Muscle strength and muscle endurance are two aspects that have to be trained systematically for the footballer to perform at optimal level besides preventing injuries． Therefore appropriate training will lead to an improvement in performance through adaptations within the muscle，such as an increase in the size of the fibres，in the number of capillaries and in the level of certain endurance enzymes． Besides muscle strength and muscle endurance the player needs good coordination and balance for an efficient performance in a kicking action．
足球运动员要想表现出最佳竞技状态并避免伤病，必须要对肌肉力量和肌肉耐力进行系统训练。因此通过适宜的训练提高肌肉的适应水平（如使得肌纤维体积增大、增加毛细血管数量、提高耐力酶水平等）来提高运动员的竞技能力。在完成一个踢球动作时，足球运动员为达到高效的竞技状态，不但应具有良好的肌肉耐力和肌肉力量，还需要有良好的协调和平衡能力。
