Abstract: The maximal peak and build-up forces at elbow flexion of 140° were measured without a wrist cuff. Peak force was found to be significantly higher than build-up force. The results established that peak force is more easiliy reproducible than build-up force. For women, the force studied did not decrease with age. The results of this investigation are believed to be useful for product designers in adjusting the product characteristics to deal with the loads exerted by users in peak force exertion.
