Aerobic training design
transtibial amputees
All transtibial amputees performed two sessions of incremental exhaustive exercise testing, separated by a period of eight weeks. The subjects enrolled in the control group (Paralympic athletes) maintained their usual physical activities and were evaluated only once. Participants in the Experimental Group (G1) underwent eight-week supervised physical training with the prosthesis. The training was performed three times a week and was supervised by a team of specialists in physical conditioning, rehabilitation, and exercise physiology. The model used in the present study was aerobic interval training lasting 20 minutes on a stationary bicycle, following the following steps: three minutes as a low-intensity stimulus in the load (watts) corresponding to VT
