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.


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


Repeated measures.


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


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.


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


Cardiovascular fatigue adversely affects postural stability.
