The team also said consistent exercise was associated with higher physical activity levels regardless of whether people exercised consistently during the morning, afternoon or evening.
"Our findings warrant future experimental research to determine whether promoting consistency in the time of day that planned and structured physical activity is performed can help individuals achieve and sustain higher levels of physical activity," senior author Dale Bond said in a statement.
“It will also be important to determine whether there is a specific time of day that is more advantageous for individuals who have initial low physical activity levels to develop a physical activity habit,” first author Leah Schumacher added.
