The study was done to find out if using better angles while running can help people start quick and move more efficiently. Ten youthful athletes who play sports with a lot of running took part in the study. They were each healthy and trained regularly.

To see how they ran, they came to two different testing sessions. They wore their usual training shoes and clothes. First, they warmed up on their own for 15 minutes. also, they rehearsed starting to run from a standing position. They did two practice runs over a 10- meter distance, with a short break in between.

After rehearsing, they started the factual tests. A experimenter told them when to start running, and they did three sprints at their maximum effort, with four minutes of rest between each sprint. They did the same test in the alternate testing session a couple of days later.

The experimenters used special equipment to record how the athletes ran. They set up three sets of timing lights and two high- speed cameras to capture the first three steps made of each sprint. They also put labels on the athletes' bodies to analyze their movements.

They used a computer program to look at different aspects of the athletes' running, like how long their way were, how numerous way they took per second, how long their bases were on the ground, and how long they were in the air. They also looked at the angles of their knees and bodies during the run.

The results showed that some aspects of the athletes' running were very similar between the two testing sessions, while others were not. e.g. their stride lengths and knee angles were quite similar, but their flight times( how long they were in the air) were not consistant.

The experimenters found out that having a quicker stride rate and shorter flight time during the third step of the sprint was most nearly linked to better 5- meter sprint times. Stride length and time spent with bases on the ground had a lower effect on sprint times.

So both better angles and focussing on a quick stride frequency might help athletes start quicker and run more efficiently.
