Context:

Previous research has demonstrated that localized leg muscle fatigue induced by lower extremity exercises (e.g., squat jumps, sprints, and treadmill running) has an adverse effect on postural stability.

Objective:

To assess the effect of cardiovascular fatigue induced by upper extremity exercise on postural stability.

Design:

Repeated measures.

Participants:

Fourteen healthy young adults between the ages of 22 and 30 years (7 male and 7 female).

Intervention:

Participants performed an exercise protocol on an upper-body ergometer to induce cardiovascular fatigue.

Main Outcome Measures:

Postural sway, represented by center of pressure excursion, during bilateral standing in two different foot positions.

Results:

In a tandem standing position, mediolateral mean distance, root mean square distance, resultant power, and centroidal frequency increased signifcantly after inducement of cardiovascular fatigue.

Conclusion:

Cardiovascular fatigue adversely affects postural stability.
