Core training improves right-foot balance, trunk strength in young tennis players: study
The trial tested an eight-week add-on program in 24 female tennis players ages 13–14. It found gains in right-foot balance and trunk strength but did not measure match performance or injury risk.

An eight-week core-training trial found improved right-foot dynamic balance and trunk-rotation strength in female tennis players ages 13–14. The randomized study assigned 24 players to core training or routine tennis training.1
The core group trained three days a week for 45 to 60 minutes alongside standard tennis practice. After eight weeks, right-foot balance rose 0.83%, forehand rotation strength rose 13.41%, and backhand rotation strength rose 12%. The control group had no significant improvement in the measured outcomes.1
The study did not measure tennis performance or injury risk, and its authors said the small, single-center sample limited broader generalization.1
