How many trials per hand are performed in the Hand Dynamometry protocol?

• A. 3 trials per hand.
• B. 1 trial per hand.
• C. 5 trials per hand.
• D. 2 trials per hand.

Answer: (A)

Grip strength measurements are affected by effort, technique, and fatigue, so using more than one trial helps you capture a true maximum rather than a fluke from a single attempt. Three trials per hand give a reliable balance between precision and practicality: enough data to average out variability, with enough rest between attempts to prevent fatigue from skewing the result. In standard protocols, you typically record the best value (or an average) from these trials for each hand, which is why three attempts are used. Fewer trials (like one or two) can miss true maximum effort, while more trials (like five) add unnecessary time and fatigue without improving reliability substantially.
