To investigate the correlation between handgrip strength and performance of knee flexor extensor muscles determined using an isokinetic dynamometer in community-dwelling elderly women.This was a cross-sectional study. Sample selection for study made by convenience, 221 (71.07 ± 4.93 years) women were included. Knee muscle measured Biodex System 3 Pro. The variables chosen analysis peak torque, torque/bodyweight, total work/bodyweight, work, average power, agonist/antagonist ratio at angular velocities 60°/s 180°/s. Assessment carried out Jamar dynamometer. Spearman's coefficient calculated to identify intervariable correlations.Only torque (60°/s) power (60°/s), (180°/s) work significantly (P < 0.05), yet poorly, correlated with (r 0.30).The majority analyses did not show any assessed Caution is required when generalizing as predictor global women.
