Brief background: Strength athletes (like weightlifters in the Olympics) frequently train their entire body in one training session. Bodybuilders tend to split their training into "body part days" (chest day, leg day, etc).
Strength athletes tend to have fewer resistance training sessions per week (3 or so) while bodybuilders might do 4-6 resistance sessions per week. For hypertrophy, current evidence is that ideal volume is 12-20 sets per body part per week.
Finding here is as long as volume is equated, there is no significant difference on either strength or muscle increase whether full-body or body part splits are used. So do whatever you prefer.
The authors note that it might be easier as a practical matter to get higher volume with body part splits. But the current evidence does not show any strength or hypertrophy benefit to one over the other.
