Postoperative rehabilitation is a period of recovery after a surgical procedure. The duration and the way of rehabilitation depends on the injuries and on the nature of the surgical procedure. A professional athlete is used to operate in order to speed up the recovery process and return to the competition. Rehabilitation as such is very important for long-term recovery and future athlete health. An effective rehabilitation program can accelerate recovery, improve the athlete's performance, and prevent future injuries. Sports injuries are, in the narrow sense, a typical injury specific to a particular sporting branch: by mechanism and frequency. Rupture of the biceps brachii in the area of the elbow is unusual. They are most often caused by sudden injury and usually result in increased hand weakness due to biceps tendon injuries in the shoulder area. In order to restore the strength of the arm as close to the normal level, it is usually recommended that the operation of the ruptured tendon be recommended. Biceps distal tendon injuries usually occur when the elbow is extended to resistance. The surgical procedure for joining the tendon should be performed during the first 2 to 3 weeks after the injury. The double muscle of the upper arm (m. Biceps brachii) belongs to the upper arm of the arm. It is a bilious muscle that performs movements in the elbow, supine and flexion of the forearm. In the bare joints of m.biceps brachii acts as a flexor when the elbow is stretched, and when the elbow is flattened acts as a strong supinator. Powerlifting competitors are trying to raise the maximum weight in one replay, but in the powerlifting competition, the three raises are: squat, bench press and dead lift. Due to workouts during training and competitions that run with intense weights, these strong forces that can be produced during these activities are considered to be dangerous and result in a number of serious or long-lasting injuries. The three most common places where injuries occur in powerlifting competitors, which are ranked by frequency: shoulder, lumbar back, knee. The three most common types of injury in powerlifting are: muscular strains, tendinitis and arthritis. The beginning of powerlifting in Croatia is considered to be the establishment of the Founding of the Federation of Forces of Power in the Yugoslavia for the Weighing of Weights in the Former Yugoslavia in 1969. Currently in Croatia, the number of competitors competing with powerlifting is more serious than 200. The most common injuries in Croatia are SI injuries. Operational reconstruction in this case was performed at the Polyclinic of Akromion, and rehabilitation was carried out according to protocol determined by the clinic. Rehabilitation has begun through passive exercises, circulatory exercises, through actively assisted exercises, all the way to resistance training. After six months of rehabilitation, the patient successfully returned to training and sports competitions. The full range of movement has been achieved. The patient received instructions and advice for further work and exercise.
