I am doing 15 min cycling each day at home and each time I try am putting maximum load (by regulating load and decreasing RPM) for periods of 1 minute and 1.5 minute. I am keeping 85-90 RPM at these loads and makes sensors to report 280-330 W load. It is a bit heightened load. But I have this idea that such heightening is good for me, because:
- It is said that one should achieve the state of sweating and gasping during workout - only by achieving such state the health of heart improves. Just walking (even large distances) or just lifting weights without seating and gasping is no especially worth for the heart;
- I just want to keep my muscles fit and my guess is that they should be exposed to the heightened load for this.
So - that is my rational for the heightening of the load during cycling. The problem is - that the frontal part (approx 5-15 cm above knee) of the leg above the knee gets tired during such workout episodes. And I don't like this sense of tiredness. It is not hurting, it is not creating some physical discomfort, it is just signal of tiredness in that place, in both lets.
I wonder - what muscles can be there? My guess is that there are very few muscles and they should not be important for the cycling. But still - this tiredness is the one single cause why I am not happy about cycling and heightened load and why I should press myself for my daily routine of cycling. When the load is under 240 W, this tiredness disappears. My base load ir 180-200W (at 90-100 RPM), I am not going below that.
So - my question is - is this sense of tiredness normal? If it is normal then how to cope with it psychologically? And if it is not normal - then what I am doing wrong? How others experience this?
But maybe there is physiological sense in such sense of tiredness - maybe it is in the interests of the body to keep such vulnerable (but insignificant) muscles with inform about achieving maximum possible load and in such why the body may prevent that maximum load is exerted e.g. on the heart and that prevents the heart to be the weakest element of the chain which should report achievement of maximum and which may experience the harm due to it.
For years I had this sense. Absolutely no problems with the knees themselves. Only now I am asking this.
