TAP reading note: Ad libitum Weekend Recovery Sleep Fails to Prevent Metabolic Dysregulation during a Repeating Pattern of Insufficient Sleep and Weekend Recovery Sleep
Weekend recovery sleep did not prevent metabolic disruption when participants returned to insufficient sleep. The result concerns a repeating short-sleep pattern, rather than every possible benefit of sleeping longer.

What the study found
Weekend recovery sleep did not prevent metabolic disruption when participants returned to insufficient sleep. The result concerns a repeating short-sleep pattern, rather than every possible benefit of sleeping longer.
Scope & limitations
36 healthy young adults: eight controls, 14 with sustained sleep restriction and 14 with weekend recovery followed by renewed restriction.
Small laboratory groups and a short exposure period limit generalization. The study does not show that catch-up sleep has no value or provide a personal sleep-debt calculator.
Population & sample
36 healthy young adults: eight controls, 14 with sustained sleep restriction and 14 with weekend recovery followed by renewed restriction.
Exposure or intervention
Five-hour sleep opportunities, with or without two days of unrestricted weekend sleep, compared with nine-hour opportunities.
Outcomes
Sleep, circadian timing, food intake, body weight and insulin sensitivity.
Time frame
Nine-night intervention patterns; the weekend-recovery group returned to restriction for the final two nights.
