Which combination of assessments could effectively estimate a client's body fat percentage?

Estimating body fat percentage accurately is crucial for assessing an individual's health and fitness levels. The combination of bioelectrical impedance and dual-energy X-ray absorptiometry (DEXA) is particularly effective for this purpose.

Bioelectrical impedance analysis works by passing a small electrical current through the body and measuring the resistance it encounters. Since fat, muscle, and water have different levels of conductivity, this method provides an estimate of body composition, including body fat percentage.

Dual-energy X-ray absorptiometry, on the other hand, is a highly precise imaging technique that differentiates between various body tissues, such as fat, lean mass, and bone mineral content. It delivers accurate body composition metrics and is considered the gold standard for measuring body fat percentage.

When used together, bioelectrical impedance offers a quick, non-invasive estimate that can be beneficial for clients who need ongoing monitoring, while DEXA provides a comprehensive and highly accurate assessment. This combination allows practitioners to cross-reference results, leading to a more complete understanding of a client's body composition.

In contrast, the other combinations of assessments listed do not effectively estimate body fat percentage as reliably. For instance, one-rep max is a measure of strength, while skin fold calipers can provide estimates of body
