Isometric measurement
Isokinetic measurement
P-value indicates differences by population. Isometric leg extension strength is shown for the AGES-REYKJAVIK cohort and isokinetic strength is shown for the Health ABC cohort. Leg extension strength could not be compared because of different measurement approaches.
