Effect of submaximal isometric wrist extension training on grip strength.

Abstract in brief

• The study investigated whether isometric wrist extension training can improve grip strength by increasing forearm extensor activation, as wrist extension stabilizes the wrist during gripping.
• Results showed that after 8 weeks of training, participants had a significant increase in wrist extension strength and grip force on the trained side, along with changes in muscle activation patterns—specifically, increased activity in wrist extensor muscles and decreased activity in flexors during gripping.
• These findings suggest that wrist extension training can effectively enhance grip strength and alter muscle activation balance, making it a promising therapeutic approach for improving hand and grip function.]
