Muscle Endurance Testing: What, Why, And How?

what is muscle endurance test

Muscle endurance tests assess a muscle or muscle group's ability to exert force and resist fatigue over time. They are a useful tool to understand your body's ability to perform essential daily tasks and improve your fitness routine. The tests can be performed with or without supervision and may or may not require equipment. Some common muscle endurance tests include the plank test, the McGill core endurance test, the push-up test, the squat test, and the flexor endurance test.

The pushup test

To perform the test, you will need a stopwatch or timer, and a ball, like a tennis ball. An exercise mat is optional. The test can be performed alone, but it is recommended to have a trainer or friend assisting to check your form and count repetitions.

Begin by getting into a high plank position with a ball under your chest, hands and toes touching the floor, body and legs in a straight line, and feet slightly apart. Practice one pushup by bending your elbows and touching your chest to the ball, then straighten your arms and return to the starting position.

The test involves repeating this movement as many times as possible while maintaining good form. The test ends when form breaks down, rhythm is lost, or you are no longer able to continue due to fatigue or pain.

For male clients, the standard 'down' position is used, with the toes as the pivotal point. For female clients, a modified 'knee push-up' position is used, with the lower legs in contact with the mat and ankles plantar flexed. It is important to ensure that the back is straight at all times and that the stomach does not touch the mat.

The number of pushups completed is recorded, and this data can be used to monitor progress and adjust workouts accordingly.

The squat test

To perform the squat test, stand with your feet shoulder-width apart. You can extend your arms in front of you or place your hands behind your ears to ensure stability and good form. Your gaze should be ahead, but slightly down to keep your spine neutral. Bend your knees and sink your hips down and back, shifting your weight into your heels. Once your knees reach approximately 90 degrees, return to the standing position. Repeat this as many times as you can.

There are variations of the squat test that can be performed to target specific muscles. For example, the Ruffier Squat Test involves measuring your heart rate before and after performing 30 squats in 45 seconds. Another variation involves squatting on your right leg until your thigh is parallel with the floor. Keep your back straight, chest up, shoulders back, and head neutral. Return to the starting position and repeat this three times for each leg.

Muscular endurance is the ability of a muscle or muscle group to exert force to overcome resistance many times. The measurement of muscular endurance is based on the number of repetitions performed. It is important to note that muscular endurance tests are specific to the assessment. Therefore, it is recommended to consult a certified trainer or physical therapist to supervise the tests and ensure proper form.

Plank hold test

Muscle endurance tests assess a muscle or muscle group's ability to exert force and resist fatigue over time. The Plank Hold Test, also known as the Prone Bridge Test, is a simple fitness test that measures core muscle strength and endurance.

How to Perform the Plank Hold Test

The plank hold test is a bodyweight exercise that targets core stability and endurance. Here is a step-by-step guide on how to perform the plank hold test:

  • Begin by getting into a push-up position, with your hands directly under your shoulders. Ensure your body forms a straight line from head to heels.
  • Engage your abdominal muscles and glutes to keep your body in a straight line. Your neck should be in line with your spine, and your gaze should be slightly ahead of you.
  • Maintain this position, avoiding sagging or lifting your hips too high. Keep your core muscles engaged throughout the duration of the test.
  • Aim to hold the plank position for a specific duration, such as 20 seconds to a minute or more, depending on your fitness level.
  • Breathe steadily and avoid holding your breath.
  • When you can no longer maintain the correct form or duration, gently lower yourself to the ground to release the plank position.

Scoring and Results

The score for the plank hold test is typically based on the total time completed. However, it is important to note that determining when the test is failed can be subjective. The test is considered failed when the subject is unable to hold their back straight and the hip is lowered.

Variations and Similar Tests

The plank hold test has variations, such as the sport-specific endurance plank test, which involves holding a basic plank position while alternatively lifting the arms and legs for 15 seconds each in eight stages. Additionally, there are similar tests like the push-up test, squat test, and the McGill Core Endurance Test, which also assess muscular endurance.

It is important to note that muscular endurance tests should be chosen based on their validity, reliability, costs, and ease of use. Additionally, it is recommended to have a certified trainer or physical therapist supervise the tests whenever possible.

Isometric tests

Muscle endurance refers to the ability of a muscle or muscle group to exert force to overcome resistance repeatedly. The measurement of muscle endurance is based on the number of repetitions performed.

One example of an isometric test is the plank test, which assesses abdominal endurance and core stability. To perform this test, the individual starts in a high plank position with their forearms on the floor, elbows directly beneath their shoulders, and toes tucked under. They then push up into a hover, keeping their body straight and rigid. The test is complete when the individual can no longer hold the position, or after a set time, usually one minute.

Another example is the isometric push-up test, where the individual holds the 'up' position of a push-up for as long as possible. Alternatively, the 'down' position can be held, which is easier for those who cannot perform a full push-up.

Other isometric tests include the isometric back strength test, where the individual holds a horizontal position while hanging over the edge of a bench for a set time, and the flexor endurance test, where the individual holds an isometric posture with their back resting against a jig angled at 60 degrees from the floor.

Upper body endurance

Muscle endurance is the ability of a muscle or muscle group to exert force to overcome resistance many times. The measurement of muscular endurance is based on the number of repetitions performed.

Upper-body endurance

The push-up test is one of the best ways to assess upper-body endurance, especially in the muscles of the chest and shoulders. To do the push-up test, get into a high plank position with a ball under your chest. Perform one practice push-up by bending your elbows and touching your chest to the ball. Make sure to straighten your arms completely when you push back up to the high plank position. Repeat this as many times as possible until your form is compromised. Alternatively, perform as many as you can in 60 seconds. Record the number of push-ups performed correctly. If you cannot do one push-up on your toes, start in the same high plank position with your back flat and your body in a straight line from the top of your head to your toes.

To assess upper body muscular endurance, you can also instruct your client to place their forearms on the floor, with their elbows directly beneath their shoulders. They should then tuck their toes under so that they touch the floor. When ready, ask them to push off the ground, hovering in the 'plank' position. Look for elevation of the hips or any shifting of position to either side. For a timed version of the plank hold test, start a stopwatch when the client is in position and stationary. Stop timing at one minute, or when the client can no longer hold the position.

The McGill Core Endurance Test is another way to assess upper body endurance. This test involves a plank hold, the squat test, and the Maximal Push test.

The Extended (Straight) Arm Hang Test is another test of upper body endurance. This test involves hanging from an overhead bar with straight arms for as long as possible.
