The 7-9 RPE group demonstrated a greater acute response of CK and LDH compared to the 4-6 RPE group.
Higher RPE training may be more effective for inducing muscle damage.

For the interaction of group by week model coefficients suggest the 7-9 RPE group demonstrated a greater acute response of CK (b = 13.43 [4.88-21.97]) and LDH (b = 13.44 [0.52-26.37]).

- Athletes aiming to reduce fat mass and preserve FFM should consume protein intakes in the range of ∼1.8-2.7 g kg(-1) d(-1).Strong
- A minimum daily protein intake of ≥1.6 g/kg is necessary to observe significant improvements in muscle mass from whey protein supplementation.Strong
- Most athletes ideally need 1.2 to 2.0 grams/kg of body weight/day of protein, preferably split across 3-4 meals.Strong
