detail required

Answer 1

During propulsion phase

Primary movers-Pectoralis major and latissimus dorsi

Wrist flexors-flexor carpi radialis,flexor carpi ulnaris,palmaris longus

These muscles maintain wrist in a neutral to slightly flexed position

Biceps brachii and brachialis causes elbow flexion

Triceps brachii -forced elbow extension

Muscles in upper limb-Thenars,Brachioradialis,flexor digitorum,biceps,triceps

Neck muscles-Sternocleidomastoid

Front trunk muscles- Pectorals,serratus anterior external oblique and rectus abdominis

Back trunk-latissimus dorsi,trapezius,spinus erectors,teres major,rhomboid major and minor

Rolling your arms causes you to use deltoid muscles

Continuation of the stroke as it enters water you use latissimus dorsi and pectoralis major

Diping of the forearm into water and pulling water makes use of biceps brachii

Rolling yourself to do another stroke makes use of your core muscles.
