RM stands for repetition maximum, therefore 1RM means the maximum weight that can be lifted only once. This test will measure the muscular strength of the lower body in one maximum effort.
Leg press machine
- The participant completes a thorough warm-up. For the first lift they need to choose a weight that is achievable and must utilise correct lifting technique
- After a rest of between 3 – 5 minutes, the participant increases the weight and tries again
- The weights are increased until the participant can only repeat one full and correct lift of that weight
- The final achievable weight is then standardised using the formula below and then compared to the norms table as a ratio
Leg press ratio = weight lifted / body weight
