CELL METABOLISM UNDER DIFFERENT INTENSITY EXERCISES IN SPORTS MEDICINE

O METABOLISMO CELULAR SOB EXERCÍCIOS DE DIFERENTES INTENSIDADES NA MEDICINA DO ESPORTE

EL METABOLISMO CELULAR BAJO EJERCICIOS DE DIFERENTES INTENSIDADES EN LA MEDICINA DEL DEPORTE

ABSTRACT

Introduction:

Articular cartilage is an essential structure for joint weight-bearing and movement. If it is always under a specific mechanical stimulation, it will cause osteoarthritis (OA) and even involve the articular cartilage. Sports can affect articular cartilage thickness, cartilage surface morphology, and cartilage cell metabolism.

Objective:

This thesis studies the cell metabolism of knee cartilage tissue with exercises of different intensities.

Methods:

We divided 40 rats into four groups according to exercise intensity. The control group exercised freely, while the experimental group exercised with different intensities. After eight weeks of exercise, we extracted the knee joint cartilage to observe its cell metabolism.

Results:

We found that the cartilage surface of the rats was complete after exercise, and the thickness of the cartilage layer was significantly greater than that of rats without exercise.

Conclusion:

Exercises of different intensities have different effects on the metabolism of cartilage cells in the knee joint of rats. Level of evidence II; Therapeutic studies - investigation of treatment results.

Keywords:
Sports; Knee joint; Cartilage, articular
