Early birds and night owls perform best at different times

Ealy RiserOur internal body clock has such a dramatic impact on sporting ability that it could alter the chances of Olympic gold, say researchers.

A study by a team at the University of Birmingham and published in the journal Current Biology, showed performance times varied by 26% throughout the day.

Early risers reached their athletic peak around lunchtime, while night owls were best in the evening.

The researchers say it could even explain why Spanish teams have more success in European football.

The body clock controls everything – from alertness to the risk of a heart attack – in a daily rhythm.

Some aspects of sporting ability were thought to peak in early afternoon but the new study suggests each competitor’s sleeping habits have a powerful impact.

They took 20 female hockey players and asked them to perform a series of 20m runs in shorter and shorter times.
And they did it at six different times of day between 07:00 and 22:00.

The results showed a peak performance in late afternoon, but then the scientists looked separately at early-type people, late-type people and those in the middle.

This time the gap between the best and worst times was 26%, and a far more complicated picture emerged.
• Larks – or early risers – peaked at 12:00
• Intermediate types peaked just before 16:00
• Owls – or late types – peaked not long before 20:00

Lead researcher Dr Roland Brandstaetter said “Athletes and coaches would benefit greatly if they knew when optimal or suboptimal performance time was.”

He said a 1% difference in performance would be the difference between fourth place and a medal in many Olympic events.
a new time.

“So if you’re an early type in a competition in the evening, then you’re impaired, so you could adjust sleeping times to the competition,” Dr Brandstaetter said.

He said such body-clock problems “absolutely” contributed to England’s struggles in the pinnacle of European football – the Champions League.
“You have players that do extraordinarily well in the English Premier League at 15:00, but they suddenly don’t perform as well in the evening in the Champions League,” he said.

He argued Spanish society, which runs a bit later in the day, may be giving teams from that country an advantage.
