- A recording sheet or digital device to document the results.
To set up the test, position the platform in a well-lit and spacious area, ensuring there is enough room for the individual to step up and down comfortably. Adjust the height of the platform to the starting level, which is typically set at 16 centimeters (6.3 inches) for adults and may vary for younger participants.
Procedure
The 4 Square Step Test follows a standardized procedure to ensure consistency and accurate results. Here's a step-by-step guide to conducting the test:
-
Explanation and Preparation: Briefly explain the test procedure to the participant, emphasizing the importance of maintaining the stepping cadence and the potential for fatigue. Ensure the participant is adequately warmed up and familiar with the stepping pattern.
-
Starting Position: Have the participant stand on the platform with their feet shoulder-width apart, facing the platform. Instruct them to step up and down with alternate feet, ensuring a two-second step duration.
-
Cadence and Timing: Set the metronome or audio device to the required cadence of 30 steps per minute. Start the timer simultaneously and ensure the participant maintains the stepping pattern in sync with the metronome.
-
Stage Progression: The test begins at the starting height, and the participant continues stepping up and down at the set cadence. After one minute, increase the height of the platform by a predetermined amount, typically 2 or 3 centimeters (0.8 or 1.2 inches). Continue this progression at regular intervals, increasing the height and intensity of the test.
-
Termination Criteria: The test is terminated when the participant can no longer maintain the stepping cadence or reaches a predetermined number of stages. It is important to observe the participant's performance and make a decision based on their fatigue level and safety.
-
Recording Results: Document the duration of each stage and the total number of stages completed. These results can be used to calculate the participant's aerobic capacity and compare their performance to normative data.
Calculating Aerobic Capacity
The 4 Square Step Test provides valuable data that can be used to estimate an individual's aerobic capacity. The aerobic capacity, often referred to as VO2 max, represents the maximum rate at which an individual can utilize oxygen during exercise. It is a key indicator of cardiovascular fitness and endurance.
To calculate aerobic capacity from the 4 Square Step Test results, you can use the following formula:
VO2 max = 25.67 + (1.79 * [Number of Stages Completed])
This formula provides an estimate of the participant's aerobic capacity in milliliters of oxygen per kilogram of body weight per minute (ml/kg/min). It is important to note that this formula is an approximation and may vary based on individual factors such as age, gender, and fitness level.
