It feels good to swear when you're lifting - particularly when the weight you're pulling is slightly too heavy.
Dr Stephens and his team conducted two experiments during the study.
They asked a group of volunteers to swear repeatedly in "an even tone" while either intensively using an exercise bike for a 30 seconds or gripping a device created to measure hand strength. This test was carried out first after participants had sworn and was then completed again after not swearing.
And the results revealed those who had sworn before completing the exercise had produced more power in the first experiment and a stronger handgrip in the second.
Peak power was increased by an average 24 watts by swearing, the scientists found.
Facebook to hire 3000 to review videos
In that case, it took Google just 15 minutes to delete the video but it took Facebook 24 hours to remove them from its service. He added: Just last week, we got a report that someone on [Facebook] Live was considering suicide.
"A possible reason for this is that it stimulates the body's sympathetic nervous system - that's the system that makes your heart pound when you're in danger".
The research follows a 2009 study, also by Stephens and Keele University, which found swearing can significantly increase pain tolerance.
'Quite why it is that swearing as these effects on strength and pain tolerance remains to be discovered, ' said Richard.
Swearing makes you stronger and better able to handle pain, at least that's the finding of researchers in the UK.
In both experiments the expletives led to significant improvements in performance compared with uttering "neutral" words.
Super Eagles Nigeria unmoved in new FIFA Ranking
With just seven games played during the points timeframe, there was very little movement in the rankings, with no change among the top 70 teams.
In the 10-second grip task, swearers boosted their strength by the equivalent of 2.1kg, researchers found.
Dr Stephens said study participants were invited to use a swear word they would typically utter if suffering a bang on the head.
"We have yet to understand the power of swearing fully", he added.
Calling your bike a wanker and abusing the potholes really works, according to psychologist Richard Stephens from Keele University.
Allowing volunteers to choose their own swear words ensured the words meant something to them. For the neutral word, the volunteers were asked to pick a word they might use to describe a table, such as "wooden" or "brown".
Why The Arkansas Death Penalty Case Is So Important
Cut off from the supply of drugs, many states had to put off executions or experiment with new lethal injection combinations. Thirty-one states now administer the death penalty, and lethal injection is the primary means of execution in all of them.
But in these tests, the participants' heart rates didn't rise at all, suggesting that swearing didn't trigger any kind of fight-or-flight mode. When asked to swear while submerging their hands in ice water, the subjects' "heart rates accelerated and their pain perception reduced".
