Preliminary Evaluation of Recommended Airline Exercises for Optimal Calf Muscle Pump Activity

Objectives

A preliminary study to investigate which of the recommended airline exercises for DVT prevention produce optimal calf muscle pump activity.

Methods

Four subjects were instructed to carry out ten lower leg exercises based on those recommended by airlines for DVT prevention. An EMG sensor was used to record calf muscle activity and a motion analysis system was used to ensure the exercise was conducted correctly.

Results

Statistical analysis showed significant differences in the level of calf muscle pump activity induced by the different exercises. Heel rise foot pumps were shown to induce highest levels of activity while many exercises did not induce any significant calf muscle activity at all.

Conclusion

These findings indicate that a further, more detailed examination of the exercises recommended to passengers for DVT prevention on long distance flights should be conducted to determine the potential benefit to the health and safety of the passenger.
