Question 1 · Hard
A footballer's peak isokinetic quadriceps torque is 200 Nm and his hamstring torque is 90 Nm at 60 degrees per second. What is the conventional hamstring to quadriceps ratio, and how is it interpreted?
- A1.0, the ideal ratio that every player needs
- B0.45, which lies within the normal athletic range
- C2.2, which is the normal ratio for a footballer
- D0.45, below the usual 0.6 benchmark: relative hamstring weakness
Show answerHide answer
Answer: D · 0.45, below the usual 0.6 benchmark: relative hamstring weakness
The ratio is 90 / 200 = 0.45. A conventional ratio of about 0.6 at slow speeds is the commonly cited benchmark, and even the lowest values quoted as normal are about 0.5, so 0.45 shows relatively weak hamstrings, which may raise the risk of hamstring strain and ACL injury.
- A: The ratio here is not 1.0, and 1.0 is not a required target.
- B: 0.45 is below even the lowest commonly quoted normal value.
- C: 2.2 inverts the ratio.
Remember this
Hamstring to quadriceps ratio = hamstring torque / quadriceps torque; well below 0.6 suggests relative hamstring weakness.
