Which of the following exercises is typically used to measure maximum strength of the lower extremities?

The squat is commonly used to measure maximum strength of the lower extremities due to its ability to effectively engage multiple muscle groups, including the quadriceps, hamstrings, glutes, and calves. This compound movement requires coordination and stability, making it an excellent indicator of lower body strength.

During a squat, the lifter's capacity to handle heavy loads while maintaining proper form reflects their overall strength in this area. The squat can be performed with various weights and modifications, allowing for a clear assessment of maximum strength across different fitness levels. Additionally, the squat has been widely studied and standardized in strength testing, further establishing its relevance as a benchmark for lower extremity strength assessment.

While other exercises like the deadlift, lunge, and leg press also contribute to lower body strength, the squat is particularly notable for its emphasis on functional movement patterns and its effectiveness in evaluating maximal strength capacity in a controlled manner.
