Body Weight Training Therapy: An Effective Way to Improve Cardiac Lung Endurance and Flexibility After Shin Splint Injury

The culture of running has spread throughout the world, this can be seen from various running events in various parts of the world from the 5K, 10K, Half Marathon and Full Marathon categories. Every runner has the same chance of experiencing the risk of injury, one of which is shin splints. Shin splints are injuries that are often experienced by runners caused by repeated running on hard surfaces or excessive and hard use of the leg flexors. When someone experiences an injury, there will automatically be a decrease in physical fitness, especially the physical fitness of the health component. The most important components in the post-injury phase are heart lung endurance and flexibility. Heart lung endurance will help someone supply oxygen throughout the body and flexibility will help someone in performing joint movements freely. Choosing the right therapy during and after an injury is the main key to restoring a runner's performance. This study used a quasi-experimental method with one group pretest-posttest design. The population in this study were 96 runners who were members of a running community in Yogyakarta. The sampling technique in this study used purposive sampling with inclusion and exclusion criteria totaling 30 people. The treatment was carried out 24 times with a frequency of 4 times a week. The instruments in this study were a 12-minute run or cooper test to measure heart lung endurance and a goniometer to measure joint flexibility. The results of this study are that the exercise therapy program has been proven to increase cardiopulmonary endurance through an increase in running values of 16.41% and can increase flexibility in knee and ankle ROM with an average increase in ROM of 41.52%. Exercise therapy using body weights can increase cardiopulmonary endurance and flexibility after shin splint injury.
