The Three-Minute Step Test Showed Good Construct Validity And Intra-Rater Reliability In Healthy Children Aged 7-11 Years

Step tests can assess exercise tolerance, only require a small space and are simple, safe and low cost (2). Few studies have evaluated the validity and reliability of step tests in healthy children, which means that reference values are rare (3).
