What Is Tennis Elbow?

The final exam was finally over. David and Mackle walked out of school. At this time, Mackle asked, "Another summer vocation begins. It’s so boring to stay at home every day. What about attending a hobby class?" After thinking for a while, David answered, "Look, a new tennis court was just finished in our school. We can play tennis in the next semester. Let's learn to play tennis together in the summer!" David said, "Good idea, that's the deal!"

On Saturday morning, David and Mackle came to the city gym with tennis rackets. The coach who greeted them was a big brother with wheat-colored skin. He had a lovely smile on his face. Mackle murmured to David, "Do you think our skin will be as dark as his after a summer?" David said, "Since we have been here, don’t worry about that. We should focus on learning. Look, the tennis ball is bigger than the table tennis ball. It may be much easier to catch." As the coach blew his whistle, the course started. The first ball was served by the coach. He played it hard. Then the tennis ball was like being enchanted, and it flew to the opposite side like an arrow. The tennis ball has touched the ground before David even realized it was coming. He hasn’t lifted his racket for it. In the second round, David paid all his attention on the ball and set a posture to catch it. When the ball flew over, he lifted his racket. Finally, he succeeded in returning the ball. He jumped for joy. "Great!" the coach gave him a thumbs-up.

After a few lessons, it was time for class again, but David frowned and stood in front of the door. He was reluctant to leave for the class. His dad asked in curiosity. “David, you have a tennis class with Mackle today, right? Why you haven’t started off yet?" He said, "Dad, I don't want to learn it anymore. It’s boring." His father asked again, "What's wrong? Is it too exhausting?" He nodded and replied, "I felt that my elbows are a little sore recently."

Dad said, "You may have got a Tennis Elbow. The skeletal system is the supporting system, which maintains the shape of the body and protects the internal organs. Every movement is made through cooperation within bones and muscles, ligaments as well as tendons. However, repeated physical tension can damage the tendons connecting muscles and bones. For example, there is a common injury, which occurs on the tendons of the elbows. For this muscle can pull our hand backward like a backhand, this damage is often called 'Tennis Elbow'. When playing tennis, we have to use our elbows frequently. This will exert pressure on that tendon and cause some small lacerations. You will feel sore around the elbow joint. This is the time when you need to have a rest in case of aggravating the injury."

"How to prevent this injury?" asked David.

His dad replied, "There are several ways to prevent it. Firstly, you must master the stroke action taught by the coach correctly. The big arm and forearm should keep at a fixed and flexible angle whether we swing them forward or backward. Secondly, use the strongly-supportive wristbands and elbow pads to protect the wrist and elbow. You can also wrap the forearm muscles with the elastic bandage. You have just had this feeling, so you cannot practice until you have recovered, or your injury will aggravate."

"Ok, I will take a break for a while. When I come back to practice, you can buy me some wristbands and elbow pads," said David.
