CCFT and Aerobic Threshold
Case 1 remained a positive grade 3 in the CCFT throughout the study. Case 2 was initially scored as a positive grade 1 in the CCFT, managing the requirements with shaky and uneven movements, but improved to a positive grade 3 post intervention.
As shown in Fig. 3, Case 1 managed a working HR of 100 during the first session and 126 in the last session. The exercise intensity, as a percentage of a calculated maximum HR, went from 55% in the first session to 70% in the last session. Case 2 managed a working HR of 119 during the first session and 138 in the last session. The exercise intensity went from 73% in the first session to 85% in the last session. Both cases experienced no aggravation of symptoms during the exercise.
