Dietary supplement for the prevention of injuries from athletes

Dietary supplements for the prevention of injuries by athletes: Complete leadership

I. Fundamentals of sports injuries and the role of prevention

A. The prevalence and types of sports injuries:

Sports injuries are an inevitable part of an active lifestyle, especially among professional athletes and lovers involved in intensive training. The prevalence of sports injuries varies depending on the sport, the level of training of the athlete, the quality of equipment and compliance with safety rules. For example, contact sports, such as football, hockey and basketball, are characterized by an increased risk of injuries due to direct clashes, falls and sharp changes in the direction of movement. Sports that require repeated movements, such as running, swimming and tennis, increase the risk of overstrain injuries.

The most common types of sports injuries include:

1. Stretching and bursts of ligaments: These injuries occur with excessive stretching or rupture of ligaments – connective tissue connecting the bone in the joints. Most often there are stretching ankle, knee (cross -shaped and side ligaments) and wrists. The severity of sprains is classified from the first (light stretching) to the third (full gap) degree.

2. Stretching and muscle tears: Like sprains of ligaments, muscle stretching occurs with excessive stretching or rupture of muscle fibers. Most often, the muscles of the back of the thigh (Hamstring), calf muscles (Calf Muscles) and quadriceps suffer. Risk factors include insufficient warm -up, overtraining and poor flexibility.

3. Knee injuries: The knee is a complex joint, subject to various injuries, including ruptures of meniscus (cartilage gaskets), damage to the cross -shaped ligaments (front and rear) and damage to the side ligaments. Knee injuries often require surgical intervention and prolonged rehabilitation.

4. The shoulder joint injuries: The shoulder joint is one of the most mobile joints in the body, which makes it vulnerable to dislocations, subluxations, ruptures of the rotational cuff of the shoulder (groups of muscles and tendons surrounding the shoulder joint) and damage to the joint lip (Labrum).

5. Bone fractures: Bone fractures can occur as a result of direct strokes, falls or stress overloads. Stress fractures are small cracks in the bones that occur as a result of repeated loads, especially in runners.

6. Tendinites and tendinoses: These states are characterized by inflammation (tendonitis) or degeneration (tendinosis) of tendons – connective tissue connecting the muscles with bones. The most common tendonites of the Achilles of the tendon, elbow joint (tennis elbow and elbow of the golfist) and knee joint (the knee of the jump) are found.

7. Bursites: Bursites are inflammation of the brush – small bags filled with liquid, which soften friction between bones, tendons and muscles. The most common Bursitis of the shoulder joint, elbow joint, hip joint and knee joint.

8. Brain concussions: Brasses of the brain are light traumatic brain injuries caused by impact on the head or sudden movement of the head. Symptoms may include headache, dizziness, nausea, loss of memory and confusion.

B. The importance of injury prevention:

Prevention of injuries is a critical aspect of sports medicine aimed at reducing the risk of injuries and improving sports results. An effective injury prevention program includes:

1. Reducing pain and discomfort: Injuries cause pain, discomfort and limitation of mobility, which negatively affects the quality of the athlete’s life. Prevention of injuries helps to avoid these unpleasant sensations.

2. Reduction of recovery time: Injuries require time to restore, which can take weeks, months or even years, depending on the severity of the injury. Prevention of injuries avoids a long break in training and competitions.

3. Improving sports results: A healthy athlete, not subject to injuries, has the opportunity to train more efficiently and sequentially, which leads to an improvement in sports results.

4. Extension of a sports career: Regular injuries can lead to premature completion of a sports career. Prevention of injuries helps athletes to remain active and competitive for a longer period of time.

5. Reducing financial costs: Treatment of sports injuries can be expensive, including doctors, diagnostic procedures, surgical intervention, rehabilitation and medicine. Prevention of injuries allows you to reduce these financial costs.

6. Improving psychological well -being: Injuries can adversely affect the psychological state of the athlete, causing stress, anxiety, depression and a decrease in self -esteem. Prevention of injuries helps maintain positive attitude and self -confidence.

C. Key elements of injury prevention:

1. Proper warm -up and hitch: The warm -up prepares the body for physical activity, increasing blood flow to the muscles, increasing body temperature and improving flexibility. The hitch helps to gradually cool the body after training, reduce the risk of muscle pain and improve recovery.

2. Adequate physical training: Power training, endurance training, training for flexibility and coordination training – all these are important components of physical training that help reduce the risk of injuries.

3. Correct technique for performing exercises: Incorrect technique of performing exercises can lead to overload of certain muscles and joints, increasing the risk of injuries. It is important to master the correct technique of performing exercises under the guidance of a qualified coach.

4. Corresponding equipment and equipment: The use of appropriate equipment and equipment, such as protective helmets, knee pads, slabs and shoes with good shock absorption, helps reduce the risk of injuries.

5. Sufficient rest and restoration: Obraining is one of the main causes of sports injuries. It is important to ensure enough time to relax and restore between training and competitions.

6. Adequate nutrition and hydration: Proper nutrition and hydration provide the body with the necessary nutrients and fluid to maintain muscle health, bones and joints.

7. Timely seeking a doctor: If pain or discomfort occurs during or after training, you must consult a doctor in a timely manner for diagnosis and treatment.
