( 38 ) provided quantitative evidence on the importance of intervention duration, finding that longer interventions (>3 months) showed greater effects on body composition (SMD = −0.40, 95% CI: −1.13 to 0.33) compared to shorter interventions (≤3 months, SMD = −0.02, 95% CI: −0.33 to 0.30), although the difference did not reach statistical significance ( p = 0.24).
