during very hard acceleration... when you are making your foot/leg speed increase greatly... your arm swing speed must keep pace with your legs to keep you counterbalanced. (based on short track ice). If your arms cannot swing fast enough your arms can over-rule your leg speed.

This is where 'arm muscles' (or perhaps more correct 'arm swing speed') make a difference.
