This is a normal phenomenon. You are now in a fatigue period, so you must stick to it and eat more fruits and vegetables, which are high in vitamins. Because I am a sports student and also practice basketball, I should pay more attention to controlling the ball, take vitamin B2 when necessary, effectively recover my physical strength, and take a hot bath to relieve lactic acid accumulation in my body. The above is all my experience, I hope I can help you.
