On the Impossibility of Optimal Hypertrophy of Biarticular Muscles: A Theoretical Support for Lengthened Partials

Aryan Phadke

Abstract: Biarticular muscles possess a multifaceted significance in the context of exercise selection. This is due to their ability to perform functions across two joints. This paper aims to investigate the underlying factors that render the achievement of optimal hypertrophy in biarticular muscles unattainable. It is posited that the conditions of peak contraction and stretch, while under active tension, are imperative prerequisites for achieving optimal hypertrophy. In this paper, we shall focus on three biarticular muscles: triceps brachii (long head), rectus femoris, and hamstrings group. We shall also analyze why the common compound movements fail to provide adequate hypertrophic stimulus to the target biarticular muscle. The reductio argument explored in this paper provides a theoretical basis for the superiority of lengthened partials in providing hypertrophy.
