Table 4 Footstrike angle (FSA) and footstrike distribution [rearfoot strike (RFS) for FSA > 8° and non-rearfoot strike (non-RFS) otherwise42] for South East Asian (SEA) and non-South East Asian (non-SEA) runners at endurance running speeds.

From: Non-South East Asians have a better running economy and different anthropometrics and biomechanics than South East Asians
