You need to pay attention to composition and shooting angles when photographing sports. Each type of sport usually has a different angle. For example, in skateboarding you can take angles below and close up to show the height of the athlete's jump.

You can compare it with the photo below which was taken from quite a distance. The jumps look smaller and less dramatic.
Both images were taken with the same lens at different angles and distances. In the image on the left it looks like he jumped two-thirds of the frame, while in the image on the right only one-third of the frame.
Another example is the sport of water skateboarding, it is recommended to shoot from a further distance because it can show the full action and drama.

If you shoot from a fairly close distance, you won't be able to get all the conditions and situations in the sport. But the advantage is that you can target the athlete's expression.
Apart from that , you also need to pay attention to accurate timing in aiming. Make sure you shoot at the peak of the action so that the results are maximum. As in the picture below the athlete is caught in his highest jump. His body posture reflects his position and direction of movement.
