When Piccolo took off his white cape before he fought Radditz, Radditz was constantly scanning him and realized that his power level increased after he threw away his cape (which was claimed to be very heavy).
Another example was Gohan as a child while he was captured in Radditz' capsule, Gohan got angry and Radditz' scouter gave him an increasing number, after that Gohan broke free out of the capsule and "headbutted" Radditz pretty strong.
Another time was after they Z group trained for the arrival of Nappa and Vegeta, Piccolo physicly (IIRC) killed several Saiba Men (plant warriors) which all were on Radditz level (1200).
On Namek, Piccolo fused with Neil and was able to physicly challange the 2nd form of Freezer
I would maybe agree that the biggest part of the amp via training is energy based but def. not all.
