more than 10 million sports-related injuries occur in the world every year
0:07
to avoid this athletes and coaches alike are using a variety of pre-competition
0:11
techniques to decrease injuries and increase performance
0:14
but what decides tell us about stretching and warming up
0:17
many studies have looked at how stretching kenna backed up by the
0:21
and it turns out it depends on the activity sports such as figure skating
0:25
and snowboarding which require a wide range of motions to impress the judges
0:28
certainly benefit from a nap its flexibility but for Powersports like
0:32
speed skating in bobsledding
0:33
too much stretching may actually cause a temporary decrease in muscle strength
0:38
the overstretched muscle becomes less responsive against a weakened for up to
0:42
although athletic competitions can be strenuous there's little evidence to
0:45
suggest that stretching before or after a competition
0:48
decreases muscle soreness some studies have even noted that extreme flexibility
0:52
can lead to an increase in the range of stretching
0:55
without pain and if you can't feel pain the body doesn't know when to stop
0:59
as a result injuries can occur another large study about Leeds found that the
1:03
least and most flexible participants were 2.5 times more likely to incur an
1:08
so when it comes to flexibility in competitive sports its most beneficial
1:13
flexible a well-designed warmup is also extremely beneficial
1:16
the term itself comes from the positive effects appraising the temperature
1:19
everybody before competition
1:21
slowly increasing physical intensity prior to a sport increases muscle
1:25
ultimately allowing your muscles to contract more forcefully
1:28
more forceful contractions equals more strength and power
1:31
furthermore slowly adding movement your muscles opens up the blood vessels
1:35
allowing blood to flow more
1:36
easily throughout the body and decreases the strain on your heart
1:39
finally as your blood temperature increases your blood cells actually hold
1:44
this loose oxygen is then free to be used by your muscles increasing overall
1:48
sign says it's important not to overstretch it when it comes to
1:52
but physically warming up your body before each specific sport might help
1:55
you burn the competition
1:56
don't forget we have a new video every day during the Olympics
2:00
can't wait our meeting partners at the CBC already have by the videos up now
2:05
