The major muscles used during backstroke

Last Updated on April 18, 2024 by admin

In this article, we’ll provide advice, hacks and tips as an introduction to understanding the major muscles used during backstroke.

• We’ll identify and explain the function of each of these muscles during the different phases of the stroke.
• Provide suggested dryland exercises to develop the major muscles used during backstroke.
• We’ll also provide a free downloadable chart ‘The major muscles used for backstroke’.

Backstroke an overview

Backstroke is the only competitive stroke performed on the back.

• It’s the second slowest of the competitive strokes, after breaststroke.
• The propulsion is generated from alternate arm stroke and flutter kick actions.
• The rotation of the swimmer’s shoulders, trunk and hips plays an important role in ensuring that their arms and legs are in the optimum propulsive positions.
• Backstroke uses a combination of two types of kick, the flutter kick and the underwater dolphin kick.

Dryland training

Many competitive backstroke swimmers regularly undertake dryland/land training.

• This can help them gain additional benefits beyond those achieved by training in the water alone.
• These include increased power, strength, endurance, speed, and coordination.
• Dryland/land training can also help increase a swimmer’s range of movement and make them more flexible.
• It can also help to correct any muscle imbalance caused by poor stroke technique or overuse.
• The combination of increased flexibility and stronger, more balanced muscle groups can lower the risk of injury.

Listed below are the major muscles used during backstroke.

Please note, that wherever possible we have used the common terms for each muscle and listed the technical/medical term in brackets. For example, the chest muscles (pectorals)

Upper/middle back muscles (latissimus dorsi ‘lats’)

The upper/middle back muscles are engaged during the pulling movements in the arm stroke.

Chest muscles (Pectorals ‘Pecs’)

The chest muscles are engaged during the pulling movements in the arm stroke.

Upper arm muscles (biceps and triceps)

The upper arm muscles are also engaged during the pulling movements in the arm stroke.

The shoulder muscles (deltoids and rotator cuff)

The shoulder muscles help to stabilise the swimmer’s upper body muscles and enable the body’s rotation to help maximise propulsion.

Hip flexors (rectus femoris and iliopsoas)

The hip flexor muscles help to initiate the downbeat to maximise propulsion during the leg kick.

Hamstrings

The hamstrings help the swimmer to recover their legs and to maximise propulsion during the leg kick.

Thigh muscles (quadriceps ‘quads)

The thigh muscles also help the swimmer to recover their legs and to maximise propulsion during the leg kick.

The buttock muscles (glutes)

The buttock muscles help to stabilise the swimmer’s body position and to maximise propulsion during the leg kick.

Calf muscles (soleus and gastrocnemius)

The calf muscles help the swimmer to maximise propulsion and to keep their legs and feet in a streamlined position (plantar flexion).

Core (abdominal) muscles

The core muscles help to stabilise the swimmer’s body, helping it maintain an effective position in the water to minimise drag and enable the body’s rotation to help maximise propulsion.

The major muscle functions during backstroke

Below is a brief explanation of the function of each of the major muscles during the different stages of the backstroke.

The upper-body muscles

• The swimmer engages their shoulder muscles (deltoids and rotator cuff).
  • This helps initiate their body’s rotation to help lengthen their stroke and maximise propulsion.
• The swimmer initiates the catch phase by engaging the muscles in the upper/middle of their back (latissimus dorsi) and the chest muscles (the pectorals).
• The swimmer’s upper arm muscles (biceps and triceps) become engaged.
  • To help flex and extend their elbow during the propulsive middle and end of the stroke
• The wrist flexor muscles help to maintain the swimmer’s wrists in the optimum position

The lower-body muscles

Backstroke uses two types of kick, the flutter kick and the underwater dolphin kick.

• They both start with a contraction of the hip flexors (rectus femoris and iliopsoas) during the upbeat which provides the major leg propulsion.
  • As the swimmer extends their knee/s, they engage their thighs (quadriceps).
  • As they recover their leg/s with the upbeat kick, the swimmer’s buttock (glutes) and hamstring muscles contract to extend their hips.
  • Throughout the stroke, the swimmer engages their calf muscles to help maintain a plantarflexed position with their feet (ankles extended & toes pointed)

 The core (abdominal) muscles

• The major core muscles are the stomach (abdominal) and side abdominals (obliques)
  • They help to stabilise the swimmer’s body, helping it maintain an effective position in the water
  • This helps to maximise propulsion and minimise drag.
  • The swimmer’s core should be engaged throughout the stroke, especially during both the arm pull and the leg kick phases.
