Rate-of-force development

1. Rate-of-force development has no effect on gait speed in humans.

   “RFD and impulse were not significantly associated with gait performance in either group.”

1. Cognitive impairment is associated with rate-of-force development in humans (51.0±25.7 vs 72.94±26.51, p<0.05).

   “RFD was significantly lower in males with a cognitive impairment (51.0±25.7) relative to males without (72.94±26.51; p<0.05).”

1. Rate-of-force development predicts sarcopenia in humans (AUC: 0.841, accuracy: 83.3 %).

   “Furthermore, the RFD had high discriminatory accuracy (AUC: 0.841, accuracy: 83.3 %).”

1. Rate-of-force development is associated with walking speed in humans (r = 0.389).

   “Significant positive correlations were found between grip strength, walking speed, and SMI index and vertical peak force (r = 0.446, 0.306, 0.338), RFD (r = 0.264, 0.389, 0.159).”
