Shorter cranks are very beneficial to avoid an extreme hip flexion when pedal at the top position. Also, the short length is helping an aerodynamic position.

A great story written on a narrow and steep road in north London by Mat Ilic.
Electromyography (EMG) analysis support the bike fitting process revealing muscles (quads, hams, glutes) activation during cycling. In this session EMG (see fig.1) revealed a decreased strength at left glute compared to right glute. This has impact on pedal stroke as you can see in fig.2 where is shown circa 30 watts difference between right and left pedal stroke.

How to tempt people to leave their car at home getting points reward for each cycling ride. https://www.bbc.co.uk/news/av/stories-45940844/the-city-that-gives-you-free-beer-for-cycling Have a look at your saddle, if you notice worn out aspects or even a mild change in shape, it's time to change your saddle. Old saddles can give a false comfortable sensations but changes in shape can trigger adaptive postural and muscular activations, decreasing performances and increasing the risk of injury.

Interesting paper by R.Verma et al.reviewed by Paul Visntini on bikefit parameters and how they related to comfort and pain, as well as fatigue, muscle activation, pedal force, centre of pressure (COP) and cadence.
