Force-frequency relationship curves. Each symbol represents one rat; Old (filled circle), Old radiation (open triangle), Young (open circle), Young radiation (filled triangle). (A) Whole nerve stimulation Old r2= .98, Old Radiation r2 = .96, Young r2 =.98, and Young radiation r2 = .98 and (B) Medial nerve stimulation Old r2 = .96, Old Radiation r2 = .96, Young r2 =.91, and Young radiation r2 =.95.
