Imagine this: you just woke up and got out of bed. Your feet hit the floor and your legs buckle. They are in absolute agony – yesterday’s run has really began to haunt you.
And then you keep in mind that you forgot to stretch before and after your run. Surely that is why you’re so sore today. Is that so?
We’ve all heard about the importance of stretching before and after exercise. But does it really make a difference? Here’s what the science says.
What is stretching?
There are many differing kinds of stretching, but two of them are the commonest static and dynamic stretching.
Static stretching involves moving a muscle (or muscles) right into a lengthened position and holding it for: short period of time – often from 15 to 90 seconds.
A typical example could be to maintain your heels on the ground while leaning forward to the touch the ground with your straight knee to stretch your hamstring muscles.
Meanwhile, dynamic stretching involves actively moving muscles and joints backwards and forwards inside the available range of motion.
Common examples include swinging your legs backwards and forwards, side to side, or swinging your arms in a circle.
Stretching before exercise
The main reasons people stretch before exercising are to extend flexibility, improve performance, and reduce the risk of injury.
Although we all know stretching increases flexibilityits influence on efficiency AND damage is less clear. But let’s take a look at what the evidence says for every of them.
Flexibility
Both static and dynamic stretching increase flexibility, although static stretching appears to have some effect barely greater effect.
Short-term static stretching inhibits sympathetic nervous system (your fight or flight system), which reduces the stiffness of your body muscles and tendons. This will make you more flexible immediately after stretching.
In the long run, static stretching is believed to extend flexibility by increasing length Your muscles and tendons or simply creating you more tolerant of discomfort attributable to stretching.
Efficiency
When it involves improving performance, this may depend on the type of physical activity you perform.
If you’re going to be doing high ranges of motion – like gymnastics or dancing – then improving your flexibility after stretching will likely translate into higher performance.
On the other hand, research has shown that static stretching could cause problems degrade performance by as much as 5% in activities requiring maximum strength and power, akin to shot put and powerlifting.
This could also be as a consequence of the decreased nervous system activation we mentioned earlier, which makes it harder for your muscles to supply force.
However, significant disturbances only appear to occur during stretching over 60 seconds. Stretching for lower than 60 seconds appears to have a minimal effect on performance (about 1%).
On the other hand, dynamic stretching increases muscle temperature and the speed with which the nerves send messages to your muscleswhich might improve muscle performance.
Dynamic stretching has been shown to increase strength and power in a small amount. This may make it a greater option before dynamic activities akin to sprinting, jumping, lifting weights or playing team sports.
Trauma and pain
When it involves reducing injury, it isn’t clear whether stretching before exercise is useful.
Many studies have shown stretching has no effect. However, many of them focus on the effects of stretching on all kinds of injuries, which can not show the true effect of stretching.
For example, a broken arm from a tackle might be grouped with a calf strain, nevertheless it would appear logical that stretching could be more likely to scale back the risk of a calf muscle strain than a broken arm.
AND last review examined the effects of stretching on various types of injuries and located that static stretching could reduce the risk of muscle, but not tendon, injuries. So far, there isn’t a evidence to suggest that stretching would cut back the risk of bone fractures and phone injuries.
There is little research examining whether dynamic stretching alone can reduce the risk of injury. One study have shown that dynamic stretching can improve joint stability, which can reduce the risk of joint injuries (akin to ankle sprains). However, further research is required before any conclusions will be drawn with certainty.
Many people also stretch before exercise to stop muscle soreness after exercise. However, research has shown Stretching before exercise has no significant effect on muscle soreness after exercise.
Stretching after training
The main reason for stretching after exercise is to enhance recovery and reduce muscle soreness. The hottest method is static stretching.
However, as with stretching before exercise, research doesn’t show that stretching after exercise reduces the intensity of exercise muscle damage or soreness.
This has also been suggested really intense stretching can damage your muscleswhich can even worsen muscle soreness. However, this will not be a consistent finding and should only occur to certain people.
However, stretching works promote leisure. Gentle stretching will be an excellent method to loosen up after an intense exercise session.
So what should you do?
Maybe lack of stretching is not the reason for pain after running in spite of everything. Your legs probably hurt because you simply ran further or harder than usual.
However, this doesn’t mean that you should not stretch.
Available evidence suggests that performing dynamic stretching before exercise will increase flexibility and improve performance, whether you plan to run, play a team sport, or lift weights.
Static stretching will be great if you want to extend your flexibility, just don’t do it right before intense exercise. And after exercise, gentle static stretching may also help your body move right into a more relaxed state.
