Harward Step Test measures

  • A.Muscular efficiency of the knee muscles
  • B.Cardio-respiratory efficiency
  • C.Cardio-pulmonary index
  • D.Respiratory pulmonary index

Answer: B

The Harvard Step Test measures cardio-respiratory efficiency, which is the ability of the heart and lungs to supply oxygen during exercise. The subject steps on and off a bench at a fixed rate for a fixed time, and the pulse rates during recovery are used to calculate a fitness index. It is not a test of the muscular efficiency of the knee muscles. The terms cardio-pulmonary index and respiratory pulmonary index are not the name of what the test is for.
