Background: Hand grip strength could be influenced by gender, age and handedness. Aim: To describe differences in grip strength for age, gender and upper extremity handedness in non-disabled community-dwelling older adults. Material and methods: We studied 47 males aged 72.3 ± 5.6 years and 69 females 72.4 ± 6.0 years who were divided in two age groups (65-70 and ? 71 years old). Grip strength was determined by a standardized protocol using a hand dynamometer. Results: There was an inverse correlation between grip strength and age in both hands only among men (p?0.05). When analyzing both genders, there was a significant inverse correlation between grip strength and age only in the dominant hand (p?0.05). Strength was higher in the dominant hand in both genders (p?0.05). It was also higher in men, compared to women in the two age groups studied (p?0.05). Conclusions: Grip strength is higher in men than women, it decreases with age and is higher in the dominant hand.
