Your discussion topic was interesting. A noted difference revealed in the video is at the pelvis. In addition, hip torque, during aerial phases later in the race, appears to be an issue with Coleman as well. Have a hard time thinking that it's strength alone! On the other hand, Lyles late race speed indices were extraordinary...generating vertical force of 2.5 x BW and contact times of 0.08 and 0.09 inside 60 & 90 meters respectively!
