Energy balance
No significant changes were found in fat-free mass (FFM) between linear training (LT) and undulating periodization (UP) groups after 8 weeks.
Both training protocols did not lead to significant changes in fat-free mass for untrained older adults.

No significant changes were found for the study variables: FFM (Δ= 0.3±1.8 kg; P=0.679; ES=0.04 and Δ= 1.3±2.4 kg; P=0.145; ES=0.17)
Why this rating
Based on the study design involving random assignment and statistical analysis.
