Vitamins for athletes: joint support at loads

Chapter 1: Anatomy and joint physiology: the basis for understanding the need for vitamins

To understand how vitamins can support the joints of athletes, you must first disassemble the structure and functions of these complex structures.

1.1. Review of the structure of the joint:

A typical synovial joint, the most common type in the body and the most prone to injuries in athletes, consists of several key components:

Joint cartilage: Smooth, elastic fabric covering the ends of the bones in the joint. It consists mainly of chondrocytes (cartilage cells) and extracellular matrix, rich in type II collagen and proteoglycans, in particular, aggracan. The cartilage provides the sliding of the bones relative to each other, minimizing friction and shockproofing. It does not contain blood vessels or nerves, receiving nutrients from synovial fluid.
The joint capsule: A hard, fibrous shell surrounding the joint. It consists of two layers: the outer fibrous membrane and the inner synovial membrane. The fibrous membrane provides structural support and stabilization of the joint.
Synovial membrane: Lines the inner surface of the joint capsule. Is responsible for the production of synovial fluid.
Synovial fluid: A viscous fluid filling the joint cavity. Performs several important functions: lubricates the cartilage surfaces, reducing friction; provides nutrition of cartilage; removes metabolic products from cartilage; acts as a shock absorber.
Blues: Durable, fibrous stripes of fabric, connecting the bones between themselves and providing joint stability, limiting the range of movements. Consist mainly of type I collagen.
Meniski (in the knee joint): Semi -moon cartilage structures located between the femoral and tibia bones. Improve the congruence of the articular surfaces, distribute the load and amortize shots.
Bursa: Small fluid -filled bags located between bones, tendons and muscles. Reduce friction between these structures.

1.2. Joint physiology: Mechanisms for maintaining health:

The health of the joint depends on the balance between the processes of synthesis and the destruction of the cartilage, as well as on a sufficient amount and quality of synovial fluid.

Synthesis and destruction of cartilage: Chondrocytes constantly synthesize the new components of the extracellular matrix (collagen and proteoglycans) and destroy the old ones. In a healthy joint, these processes are balanced. However, with intense physical exertion, destruction can prevail over the synthesis, which leads to damage to the cartilage.
The role of synovial fluid: It provides nutrition of cartilage, since the cartilage has no blood supply. Synovial fluid also removes metabolic products from cartilage. Its viscosity and composition play an important role in ensuring smooth sliding of the articular surfaces.
The effect of the load on the joint: A moderate load stimulates chondrocytes to the synthesis of new components of the matrix, which helps to strengthen cartilage. However, excessive load, especially without enough time for restoration, can lead to damage to cartilage and inflammation.
Proprioception: The feeling of body position in space plays an important role in maintaining the stability of the joint and preventing injuries. Proprioceptive receptors are located in the articular capsule, ligaments and muscles surrounding the joint.

1.3. Factors affecting the health of the joints in athletes:

The joints of the joints in athletes are affected by many factors that can be divided into the following categories:

Type and intensity of training: Types of sports with a high shock load (running, jumping, heavy athletics) have a greater effect on the joints than sports with low shock load (swimming, cycling). Intensive workouts without enough time for recovery also increase the risk of joint damage.
Age: With age, the water content in the cartilage decreases, and its elasticity decreases, which makes it more vulnerable to damage.
Genetic predisposition: Some people are genetically predisposed to the development of joint diseases, such as osteoarthritis.
Previous injuries: Joint injuries, such as dislocations, ligaments and fractures, increase the risk of osteoarthritis in the future.
Overweight: Excess weight increases the load on the joints, especially on the knee and hip.
Incorrect exercise technique: Incorrect technology for performing exercises can lead to an excessive load on the joints and increase the risk of injuries.
Malnutrition: The insufficient consumption of nutrients necessary for the health of the joints, such as vitamins, minerals and proteins, can weaken cartilage and ligaments.
Dehydration: Dehydration can reduce the volume of synovial fluid and worsen its lubricating properties, which leads to an increase in friction in the joint.

Chapter 2: Vitamins that support joint health: scientific rationale and mechanisms of action

Some vitamins play an important role in maintaining the health of the joints, participating in the synthesis of collagen, reducing inflammation and protecting cartilage from damage.

2.1. Vitamin C (ascorbic acid): key component of collagen synthesis:

The role in the synthesis of collagen: Vitamin C is a cofactor of the enzymes of sprayidroxylase and lyisilhydroxylase, which are necessary for hydroxylation of the sloppy and lysine in the molecule of Procollagen. Hydroxiling is an important stage in the synthesis of collagen, which ensures the stability of the triple spiral and the correct formation of collagen fibers. Collagen is the main structural component of cartilage, ligaments and tendons.
Antioxidant activity: Vitamin C is a powerful antioxidant that protects the cartilage from damage caused by free radicals formed in the process of metabolism and with inflammation.
Anti -inflammatory action: Vitamin C can reduce the level of inflammatory cytokines, such as Interleukin-1β (IL-1β) and a factor of alpha tumor necrosis (TNF-α), which play an important role in the development of osteoarthritis.
Research: Studies show that vitamin C consumption may be associated with a reduced risk of osteoarthritis and improving symptoms in people with existing osteoarthritis. However, additional studies are needed to confirm these results.
Recommendations for athletes: Athletes are recommended to consume more vitamin C than people leading a sedentary lifestyle due to increased production of free radicals during training. The recommended daily dose is 75-90 mg, but athletes may need 200-500 mg per day.
Sources: Citrus fruits (oranges, lemons, grapefruits), berries (strawberries, blueberries, raspberries), kiwi, bell pepper, broccoli, spinach.

2.2. Vitamin D (calciferol): importance for bone tissue and role in cartilage:

The role in the metabolism of calcium and phosphorus: Vitamin D is necessary for the absorption of calcium and phosphorus in the intestines, which are the main mineral components of bone tissue. A sufficient level of vitamin D helps maintain bone strength and reduces the risk of fractures.
Impact of chondrocytes: Vitamin D (VDR) receptors are found in chondrocytes. Vitamin D can affect the metabolism of chondrocytes, stimulating the synthesis of components of the extracellular matrix and protecting the cartilage from damage.
Anti -inflammatory action: Vitamin D has anti -inflammatory properties and can reduce the level of inflammatory cytokines in the joints.
Muscle strength and function: Vitamin D plays an important role in maintaining muscle strength and function, which is important for joint stability and prevent injuries.
Research: Studies show that vitamin D deficiency can be associated with an increased risk of osteoarthritis and worsening its symptoms. However, additional studies are needed to confirm these results and determine the optimal dose of vitamin D for the prevention and treatment of osteoarthritis.
Recommendations for athletes: It is recommended to regularly check the level of vitamin D in the blood and, if necessary, take supplements, are recommended to athletes, especially those who train in closed rooms or in regions with limited sunlight. The recommended daily dose is 600-800 IU, but athletes may require a higher dose (1000-2000 IU) under the supervision of a doctor.
