wowww lots of typos in Benet clients.Now here a dangerous cook book. In many cases when you do a the left and right leg assessment with 2 moxy and you have despite some slightly different placement always the same side in this case the right side with a lower SmO2 ( indicating a potential higher O2 use ) and you always see a higher tHb, indicating a higher blood flow as blood may go where it s most needed . than we have often a stronger leg in front of us. This is when you have no feedback on power. if you know like in your case left and right power is the same the cook book does no apply. The above means you simply push with the feeling and the stronger leg will show this reaction. ( often ) Why you will push so it feels equal from the effort but it feels equal because one leg is stronger and you need to push more to feel the same but it needs more energy. If you push he same load the weaker leg will have to work % wise harder so you may need more O2 , SmO2 drops and you may have a higher level of compression as you need more intramuscular recruitment so tHb often drops . As well less good trained you may have less vascularisation,again easier to see a drop in tHb due to compression and less vascularisation less mitochondria density, so possible earlier problem to desaturate. so in your caseI would consider my assessment to be controlled since it was performed on a Wahoo Kickr with the resistance set the same for both legs and all intervals. My left leg shows lower SMO2 and higher THB than right leg... so the above note tells me my left leg is stronger assuming we would see hat a few times. Same load lower SmO2 so you need more O2 than on he right side. Now if it is muscular weaker than we would often see a dip in tHb due to as well a higher muscle compression. But we do not see that. In fact we see a higher tHB 2 basic thoughts a) it is so weak that you create an occlusion trend outflow restriction and thB goes up . Easy to check with biased picture or whether after the load the tHb drops as a pooling outflow b) you are in a training phase where your goal was to increase vascularisation and this is now successful, but you are behind mitochondria density development. Before you develop mitochondria you have to increase vascular density . This than would be a great exampel of a planned idea with a successful feedback based on the NIRS reaction.My strength training workout the other night showed my left leg desaturating less than my right but with more THB... this is definitely a puzzle but fun to learn. what type of workout did you do on the bike or squatting . In squatting hard to control due to change in angles and more . The key in the workout is not to compare what is going on but to try to create the same NIRS picture with both legs. so you have the same metabolic stimulation. So with the above feedback go back to the cutting board and see, what or which leg may be possibly the weaker leg. One simple way is: simply bike for an hour in the balanced intensity and if you can test left and right -independent look , where or what side is pushing a higher wattage and than look the NIRS reaction. so try not to manipulate simply bike and to not think an have fun

lot's of emails on this topic. In short. I never do single leg in athlete if they are cyclist. I do single leg with other sports on a bike. Main reason for cycling is the muscle pattern ( harmonies) so I try always to maintain both legs as an activity on a bike and will choose off bike single leg exercises if I believe I need them to stimulate a certain target., Here a super short inside form a coordination workout last Friday late. ACL rehab and a client I showed some NIRS results. https://www.youtube.com/watch?v=VZjG6W5E7F0
