What does this rating mean?
A solid systematic review with caveats, or consistent indications with a limited scope.
Findings
A daytime nap after a normal night's sleep is associated with better physical performance, with duration and timing mattering.
Who this applies to
Physically active people and athletes who slept normally the night before, 7 to 9 hours.
Size of the research
18 studies, 15 of strong and 3 of moderate quality.
What to keep in mind
Most other performance measures, such as sprinting and jumping, were studied in only one to three studies. That is too few for firm conclusions.
Practical conclusion for REZA
A concrete, practical measure for clients who train in the evening after a long workday.
