The Singapore Army said it has not yet decided on making changes to the Individual Physical Proficiency Test (IPPT).
The Straits Times reported on Wednesday that the Singapore Armed Forces (SAF) are looking to tweak the yearly IPPT for the first time since 1982.
Sources told The Straits Times that commanders have been briefed about the likely changes, which could kick in next year, while servicemen revealed that they had taken the new tests as part of trials.
Changes could see the standing broad jump being scrapped, a push-up component added and the run extended to 3.2km.
The current test, taken by 116,000 people every year, has five stations comprising chin-ups, standing broad jump, a 4x10m shuttle run, sit-ups and a 2.4km run.
When contacted last week, the Defence Ministry declined to confirm the proposed tweaks.
The Singapore Army said on its Facebook page on Wednesday "there has not been any decision to change our IPPT system".
It added: "The SAF constantly reviews our training system, including physical training regimes and physical fitness tests, to ensure that they are relevant and effective, and continue to meet our operational requirements."
Some personnel, including operationally ready national servicemen (NSmen) who were recalled for in-camp training in July, said they had a trial of the new IPPT, in which they were asked to do push-ups, squats and the 3.2km run.
