Context:

No direct research has been conducted on the relationship between subcutaneous tissue thickness and neuromuscular electrical stimulation (NMES).

Objective:

The purpose of this study was to determine the effects of subcutaneous tissue thickness on NMES amplitude and NMES force production of the quadriceps.

Design:

Simple fixed design, testing the independent variable of subcutaneous thickness (skinfold) groups with the dependent variables of NMES amplitude and force production.

Setting:

Athletic Training Laboratory.

Participants:

29 healthy women.

Intervention:

NMES to produce at least 30% of maximal voluntary isometric contractions (MVIC) of the quadriceps.

Main Outcome Measure:

Maximal NMES amplitude and percentage of MVIC using NMES.

Results:

A significant skinfold category difference F2,28 = 3.92, P = .032 on NMES amplitude was found. Post hoc revealed the thinnest skinfold category tolerated less amplitude compared to the thickest category. A significant correlation was found between NMES amplitude skinfold category R = .557, P = .002.

Conclusion:

Higher NMES amplitudes are needed for the thickest skinfold category compared to the thinnest skinfold category.
