Question: am I truly working a different system (cardiac>skeletal muscle) when training at a higher cadence? I did a little experiment (kept HR same as this lines up best with effort level for me) and there's definitely a difference in my power output:
140 BPM @ 110 RPM x 5 min = 240W
140 BPM @ 95 RPM = 280W
Am I really training my cardiac system more when riding at a higher cadence (which is less fit apparently) or is it just mechanical inefficiency at the higher RPM making the difference?
