The use of human growth hormone (HGH) to enhance athletic performance is now banned from most major sporting events including the Olympics. To investigate the effect of HGH on athletic performance, doctors in the US looked at changes in body composition and strength in a group of athletes taking the drug. This was compared with a control group of similar athletes who had never taken the drug.

Deduce from the results of the study whether HGH improves strength.

the drug does not appear to improve strength as less mass can be lifted «by arms and legs» ✔
While this was generally done well, those who missed this mark chose to write about muscle growth rather than the mass being lifted.
