Context:

The Unexpected-Disturbance Program (UDP) promotes exercises in response to so-called involuntary short- to midlatency disturbances.

Objective:

This study investigated the effectiveness of the UDP in the last 6 wk of rehabilitation.

Design:

Pre–post study with 2-tailed paired t tests for limited a priori comparisons to examine differences.

Setting:

National Sports Institute of Malaysia.

Participants:

24 Malaysian national athletes.

Interventions:

7 sessions/wk of 90 min with 3 sessions allocated for 5 or 6 UDP exercises.

Main Outcomes:

Significant improvements for men and women were noted. Tests included 20-m sprint, 1-repetition-maximum single-leg press, standing long jump, single-leg sway, and a psychological questionnaire.

Results:

For men and women, respectively, average strength improvements of 22% (d = 0.96) and 29% (d = 1.05), sprint time of 3% (d = 1.06) and 4% (d = 0.58), and distance jumped of 4% (d = 0.59) and 6% (d = 0.47) were noted. In addition, athletes reported improved perceived confidence in their abilities. All athletes improved in each functional test except for long jump in 2 of the athletes. Mediolateral sway decreased in 18 of the 22 athletes for the injured limb.

Conclusion:

The prevention training with UDP resulted in improved conditioning and seems to decrease mediolateral sway.
