Although movement speed is an important part of tennis, when we observe professional tennis players during their match, we find that the way they move is quite different compared to a sprinter running 100 meter dash. The truth is that tennis is not just about how fast your speed is, it also requires great footwork combined with agility and balance. A sprinter only need to reach the end of the line as quick as possible, but you need to keep going and recover back to proper position in constant cycle in case your opponent sends another ball back for tennis. A lot of talented young players rely only on their natural speed and explosiveness during their plays, but with proper training .If a coach can help them to improve their footwork and movement, this will for sure make them be more efficient on court and give them the best chance to execute their tactics, hopefully also increase their winning opportunities and avoid injuries.
