About the Leg Raise Test

The Leg Raise Test measures core stability by completing as many leg raises as possible whilst supporting body weight, all in time to a beep recording. This test was used in testing for Australia's Greatest Athlete (2010), and called the Diving Challenge. Also check out the similar Leg Tuck Test.

Test Purpose

The leg raise test measures the control and endurance of the core stabilizing muscles. It specifically targets the hip flexors (iliopsoas, rectus femoris), rectus abdominis, and the deep core stabilizers that maintain pelvic control during dynamic movements. This assessment is particularly relevant for athletes in sports requiring sustained core engagement such as gymnastics, diving, martial arts, climbing, and pole vault.

Equipment Required

You will need a leg raise machine (also known as a captain's chair or vertical knee raise station) and a metronome or cadence recording. A beep recording can be created using the Team BeepTest software. The equipment should allow the athlete to support their weight on their elbows and forearms with legs hanging freely.

Pre-Test Procedures

Explain the test procedures to the subject. Perform screening of health risks and obtain informed consent. Prepare forms and record basic information such as age, height, body weight, gender and test conditions. Ensure the athlete has completed an adequate warm-up including light cardiovascular activity and dynamic stretching of the hip flexors and core musculature. See more details of pre-test procedures.

Test Procedure

The aim of this test is to perform as many leg lifts as possible, in time to recorded beeps (the original rate is not known, but may be similar to that used for the push up). The participants start in the leg raise machine, with their weight supported on their elbows and forearms and legs hanging down. When ready, the metronome or beeps are started. The subject must raise the legs (keeping the knees straight) to a horizontal position and then back again. The test is over when the subject is unable to perform the action correctly in time to the beeps.

Scoring

The score is the maximum number of complete repetitions successfully performed. A repetition counts only when the legs reach the horizontal position with knees remaining straight, performed in time with the cadence. Early termination of a repetition or failure to maintain the tempo results in test completion.

Test Advantages

This test is simple to perform and can be self-administered with basic timing equipment. It provides a reliable measure of core stability endurance that correlates well with athletic performance in core-dependent sports. The standardized cadence ensures consistent testing conditions across multiple assessments.

Test Disadvantages

The required equipment may not be readily available in all training environments. Athletes with limited hamstring flexibility may struggle to achieve the horizontal leg position with straight knees. Additionally, the test primarily measures sagittal plane core endurance and does not assess rotational or lateral core stability.

How to Improve Your Score

To enhance your leg raise test performance, incorporate a progressive core training program that includes hanging knee raises (as a regression), L-sits, hollow body holds, and plank variations. Focus on building both strength and muscular endurance with sets of 15-25 repetitions. Additionally, work on hip flexor strength through exercises like standing leg raises and resistance band hip flexion movements. Consistency in training over 8-12 weeks typically yields measurable improvements.

Frequently Asked Questions

What is the leg raise test?

The leg raise test is a core stability endurance assessment where athletes perform as many hanging leg raises as possible in time to a beep recording. It measures the control and endurance of the core stabilizing muscles including the hip flexors and abdominals, making it valuable for evaluating athletic readiness in core-dependent sports.

What is a good score on the leg raise test?

A score of 30 or more repetitions is considered good, while 40 or more indicates excellent core stability endurance. Average scores range from 20-29 repetitions. Elite athletes in gymnastics and diving often achieve scores well above 40 repetitions due to their extensive core training backgrounds.

What muscles does the leg raise test assess?

The test primarily measures the endurance of the hip flexors (iliopsoas and rectus femoris), abdominal muscles (rectus abdominis and obliques), and deep core stabilizers. It also requires adequate hamstring flexibility to maintain straight legs at the horizontal position.

How can I improve my leg raise test score?

Improve your score through progressive core training including hanging knee raises, lying leg raises, planks, hollow body holds, and L-sits. Focus on building muscular endurance with sets of 15-25 repetitions. Also incorporate hip flexor strengthening exercises and hamstring flexibility work for optimal performance.

What equipment is needed for the leg raise test?

You need a leg raise machine (captain's chair) with elbow and forearm support, plus a metronome or cadence recording to pace the repetitions. The beep rate should provide a consistent tempo for each raise and lower cycle, typically around 40-60 beats per minute for complete movement cycles.

Is the leg raise test valid for all athletes?

The leg raise test is valid for most athletes but particularly relevant for sports requiring sustained core stability like gymnastics, diving, martial arts, climbing, and pole vault. Athletes with lower back conditions, hip injuries, or limited hamstring flexibility should consult a sports medicine professional before testing.

What is the difference between the leg raise test and leg tuck test?

The leg raise test requires keeping knees straight and raising legs to horizontal, emphasizing hip flexor strength and hamstring flexibility. The leg tuck test involves bringing bent knees toward the chest, which reduces the hip flexor demand but increases the abdominal engagement. Both tests assess core endurance but through different movement patterns.
