Procedure to calculate the external power output of both hands (example for one cycle). The top figures show the procedure for synchronous handcycling. (1) The external power output as measured at the left handlebar. (2) The assumed external power output produced at the right handlebar, i.e. equal to the left. (3) The total external power output as the sum of both hands. The bottom figures show the procedure for the asynchronous mode. (4) The external power output as measured at the left handlebar. As the right handlebar is mounted with a 180 degree shift, this data is ‘cut’ at 180 degrees. (5) The last 180 degrees is placed in front of the first 180 degrees of the cycle. (6) The result of step 5, i.e. the assumed external power output at the right handlebar. (7) The total external output as the sum of both hands
