Left vs Right Hand Grip Strength

[Guest guest]

So, you are a competitive lifter and have found that you tend to lose your

grip more readily with one hand than the other during the deadlift or clean.

The following study yields some interesting information on this subject, most

noteworthy being the finding that left handers do not have any major

differences between left and right hand gripping strength.

Grip Strength: effect of hand dominance.

AIM OF THE STUDY: Reliable and valid evaluation of hand strength is important

for determining the effectivity of treatment strategies and it is accepted

that grip and pinch strength provide an objective index for the functional

integrity of upper extremity. This study was designed to evaluate the grip

and pinch strength differences between sides for the right and left handed

population. METHODS: The study included 128 right and 21 left hand dominant

volunteers. Grip strength of the participants were measured by using a Jamar

dynamometer. Pulp pinch strength measurements were performed by manual

pinchmeter.

RESULTS: When the study group was totally evaluated, a statistically

significant difference was found between the grip and pinch strengths of

dominant and nondominant hands in favour of the dominant hand. For further

information we grouped 149 participants as right and left handed and

investigated the number of subjects with stronger nondominant hand for each

group.The percentage of stronger nondominant hand grip was 10.93% and 33.33%

for right and left handed groups respectively. The results were less

significant for pinch strength with 28.12% and 28.57% for right and left

handed subjects respectively.

CONCLUSION: We concluded that the dominant hand is significantly stronger in

right handed subjects but no such significant difference between sides could

be documented for left handed people.
