Final answer:
The important muscles in the pull phase of rowing include the latissimus dorsi, rhomboids, biceps, trapezius, deltoids, forearm flexors and extensors, quadriceps, and glutes.
Step-by-step explanation:
In the pull phase of rowing, several muscles are important. The primary muscles involved are the latissimus dorsi, or the lats, in the back, the rhomboids between the shoulder blades, and the biceps in the arms. These muscles work together to pull the oars and generate the force needed to move the boat forward.
Additionally, other muscles such as the trapezius, the deltoids, and the forearm flexors and extensors also contribute to the pulling action. These muscles provide stability and assist in generating power during the pull phase. The muscles in the legs, specifically the quadriceps and glutes, are also engaged during the pull phase to help stabilize the body and provide a solid base of support for the pulling motion.
