I believe that I am not the only one who has a bad knee and thinks that it might be because of running. I used to do X-country in my high school and I did training everyday to improve myself. However, when the season goes, I started to feel pain on my knees and that bothered me a lot. Then I saw articles about how basketball players all had bad knees due to their intensive training, and I started to wonder: was it possible that running was the cause of the pain?
There is actually a word for the problem that I am experiencing: runner’s knee. Runner’s knee can be caused by multiple reasons such as misalignment and overusing of the knee.
A research done in 2003 on recreational runners showed that 844 out of 1020 people in the research process had knee injuries. The percentage was about 82.7%. The knee problems in this research included experiencing pain after exercise and other minor or more serious symptoms. This study clearly showed that running had something to do with knee injuries. Although the cause of the pain can be due to multiple reasons, like the road conditions and weather situations, it is still strongly possible that there is a positive correlation between running and knee injuries. The pressure brought to the knee through intensive exercise may be the cause to multiple knee injuries.
Another research done in 1989 showed that 73 out of 115 people who had a systematic training for marathon had different degrees of knee injuries. The percentage was about 60%. There are several possibilities that may cause the difference in those two researches. Firstly, the sizes of the research were different. One had over a thousand objects and the other only had a little over a hundred. The insufficient number of research objects may cause the result to be accurate. Also, people who trained for marathon might pay more attention to stretching and other recovering exercise that would release the pressure of running, and those exercises might reduce the injuries.
In conclusion, the experiments show a strong correlation between running and knee injuries. There might be outliers like muscle strength, race differences and body structures. However, running is still a possible suspect for all kinds of knee problems. Stretching before and after running can possibly reduce the injuries, and systematic training and recovering can protect the knees from injuries as well.
