Muscular performance and the risk of injury may depend on the balance of opposing muscle groups (Tam et al., 2017). Ab stretches are a great way to warm up or cool down before or after a core workout. It is likely that the voluntary activation of the agonist muscles is increased during strength training, but changes in coactivation of the antagonists may take place as well.

By adding weight to the mix, youre not only placing more strain on the muscle thats tensed (the agonist), but youre also increasing the amount your antagonist muscle needs to stretch to offset the strain on the agonist. When we flex our arm (with a bicep curl, for instance), the bicep is contracted, making it the agonist muscle, and the tricep is relaxed, and therefore the antagonist muscle in this scenario.

(2012). Knee joints are hinge joints. WIIT split squat benchon wiitraining.com. As weve seen with previous agonist and antagonist muscle pairs, these roles are reversed as we return to a natural position, with the trapezius now the agonist muscle, and the pectoralis major the antagonist muscle.

The biceps counteract the movement by the triceps. In these instances, flexibility exercises for the calves and possibly joint mobilization for the ankle may be required to regain 15-20 of ankle dorsiflexion. This study proposed the analysis of the Magnitude Squared Coherence (MSC) between agonist-agonist (AG-AG) and agonist-antagonist (AG-AN) muscle pairs in a group of 9 post stroke participants compared to 32 healthy controls. One of the functions of that muscle will be to aid or cause movement around that joint. As weve previously mentioned, the bicep curl goes through two main motions - the lift, and the subsequent relaxation.
