Left balance 70-30

Hi, I was wondering if extremely left right balance is making a difference?

An accident made my right side weak. I train without a power meter for some time. Now, I got a power meter and balance is constantly reading 70-30.

I always feel like the easy days are too easy. Any thoughts?

Ps putting the workout in zwift in fabulous.

That imbalance seems excessive… what power meter are do you have?

That much imbalance should be immediately obvious in single leg strength movements like squats, box steps, etc. Can you stand up using your right leg? I broke my left hip last year and the worst I saw for power balance was 40-60 during recovery (once it had healed enough to ride). It took months of dedicated single leg strength training to get my power balance back to normal.

Sounds like a question for a physical therapist.

Yes, it certainly makes a difference because the 70 side shows what your general body/genetics are capable of.

That being said, depending on the extent of your injury and your recovery, the 70/30 ‘could’ be the best you can ever achieve.

Also, depending on the injury, it could be worth seeing a PT for additional rehab. If you are generally fully recovered and without major limitations, you would be best served doing a lot of strength training, particularly with isolation exercises for each leg to regain strength.

In 2022 I completely tore my conjoined tendon in my left hamstring and didn’t have it repaired. In 2023 I had hip surgery on that same side. Within 6 months of the surgery, I was right around 50/50 power balance, so (depending on the injury) it’s certainly possible for many scenarios.

I think bike fit also needs to be taken into consideration.

For instance, does the balance change if the saddle is lowered by a few mm?

A proper fit can be a great help when coming back from an injury.

Good luck

I have the favero assioma duo.

I can stand on right leg for about max 30 seconds. Originally, I was a runner but spasticity made it impossible to continue. Brain injury sucks.

I have tried to do a bike fit but I will try to lower the seat.

Thanks for your help!

Ah so it is definitely a real imbalance - sorry to hear that.

With the favero there are a few settings you need to check on the favero app to make sure you are definitely getting power data from both sides and are not just the left side instead.

If you are connecting your pedals via ant+ then you will be fine - you will always get the correct total power that way.

If you are connect via Bluetooth however, favero have implemented a few options to ensure compatibility with different app and some are wrong for TrainerRoad.

For the correct setting in the favero app go to “compatibility with other apps” and choose “Unified Channel L”. This will ensure that you’re sending data from both pedals to TrainerRoad via a single connection to the left master pedal.

Many times I have found the issue to be with stabilizing muscles (posterior chain and hip abductors and adductors) rather than the primary drive muscles (Vastus medialis and lateralis).

This can’t be emphasized enough.
