The practical, science based guide to post exercise recovery

If you play sport or workout a good warm-up will help prepare your muscles: increasing your performance, decreasing your risk of injury, and maybe reducing your post exercise soreness. We reviewed 27 clinical trials and other scientific papers, and found that while some routines are useful other common ones are of little benefit and can even hurt you.
In this article we look science says about each of your different warm-up options, then show you how to put together the most appropriate routine for your needs.
Tight muscle can easily tear, so you can help prevent injuries by stretching or relaxing muscles to their full operational length. However, if you stretch too far it can allow joint to move more than normal and be injured (1,2). This should not be a problem with any of the massages, or dynamic warm-up exercises that use normal movements though.
You will read claims that because massages and warm-ups do things like increasing blood flow they increase performance (3–6). However, there have been a lot of clinical trials that tell us whether they actually do or not. We will share these results in the next section.
Conventional massage is where a therapist uses manual techniques such as rubbing, pressure and kneading. This will vary depending on the skills of the therapist and the needs of the client.
Conventional massage can help flexibility, but should not allow excessive joint movement. Therefore, it should help reduce the risk of muscle strains and tears.
Convention massage may help flexibility, but according to the most recent review of clinical trials there is no evidence that massage has any effect on strength, endurance or fatigue (7).
Several trials show that massage after exercise helps recovery (8–12) but we could not find any testing massage as part of a warm up.
Vibration massage is where the vibrating pad of a vibration massager is placed on the muscles and the vibrations allowed to penetrate. This is very similar to the way ultrasound works. Ultrasound is just vibrations at a higher frequency. Therapeutic vibration massage has several huge benefits.
Vibration massage can increase flexibility (13) but should not allow excessive joint movement. Therefore, it should help reduce the risk of muscle strains and tears.
According to the results of many clinical trials the application of vibration massage of 30-60 Hz before exercise will enhance strength (14,15), and increase the time taken for muscles to fatigue (16).
Vibration massage before exercise will decrease post exercise soreness (8,17).
Foam rollers are devices that enable users to self apply pressure that imitates the techniques that professional therapists use. They are heavily advertised, and promote self massage.
Foam rolling initially increase flexibility, but this increase only lasts less than 10 minutes (18–20). Therefore, any benefits will likely be gone before you compete.
Clinical trials have shown that foam rollers give no improvement in performance (18,21–24).
Clinical trials show that foam rolling after exercise has only negligible benefits. We could not find any trials that tested using them before exercise.
For the reasons shown in this pic foam rolling will not give you the same results as a massage by a professional therapist. It is also important to note that In the real world people use them without professional supervision of a clinical trial. Therefore, results are often much worse.
Conventional stretching is where muscles are placed under gentle tension causing them to lengthen.
Stretching exercises have not been shown to reduce the rate of injuries (1,2). Scientists believe that while lengthening muscles will reduce the risk of strains and tears, allowing the joints to move more than normal can increase the risk of joint injury. If you do stretches as part of a warm up limit the stretches to normal movements of your joints.
Trials show that conventional static stretching will give a prolonged increase in flexibility, but actually decrease performance (2,25).
We could find no trials that tested this.
A dynamic warm-up means doing movement or activities such as exercising. Scientists advise that the best dynamic warm ups incorporate or mimic the movements or activities of the sport or exercise. The basic principle is to put the joints and muscles through the activities they will be performing with gradually increasing intensity, without causing fatigue.
Dynamic warm-ups have been shown to increase flexibility (26), but should not force joints beyond their normal movements. They should help reduce the risk of injury.
Dynamic warm ups have been shown to increase strength, and in one trial found that compared with no warm-up dynamic warm-ups actually increased the height an athlete could jump by 2” (5cm) (26,27).
We could find no trials that tested this.
Percussion massagers are a hybrid machines that try to combine vibration and conventional massage. In this diagram the device on the left is a vibration massager while the tool on the right is a t-bar which therapists use to save their thumbs and apply deep (painful) pressure. As you can see massager gun makers have basically converted the a t-bar into a “jackhammer” designed to drive it’s head into the muscle.
The idea of combining vibration and conventional massage is an excellent marketing gimmick, but the reality is that they deliver far less therapeutic vibrations than a genuine vibration massager, while driving the head into the muscle has no proven benefit and is potentially very harmful. Colleagues tell me that they have seen lots of damage caused by massage guns, and there is even a report in a scientific journal of a person who nearly died from injuries received trying to help her muscles recover after cycling (2). For more information please see our article Are massage guns effective- beyond the hype .
Marketers use the results of clinical trials of vibration to support the use of their machines, but as you have seen they deliver far less therapeutic vibration than a genuine vibration massager. There have been trials of “percussion” massagers but what the scientists do is use special damper heads that spread out the contact to increase the vibration transfer, and stop the head punching into the muscles like a jackhammer. What they effectively did is modify their machines so they were more like vibration massagers so they would get better results in the trials and not hurt people, but for marketing purposes the title of the report says “percussion”. For more information please see or article on the lack of science of massage guns.
For your easy reference we have summarised the benefits of each warm-up activity in a table below. We see articles and videos with titles such as “The five best warmup exercises”, but clearly to get the most benefits you need a routine that combines the benefits of different activities and that is tailored to the sport and exercise you are about to do. Here are some general guidelines.
Standard disclaimer: this is not specific advice, just general information to be discussed with your own health care professional.
Dynamic warm ups have very positive benefits. It is important to chose the exercises that incorporate or mimic the activity you will be doing. The basic principle is to start slowly and increase intensity. You should aim to put your joints and muscles as realistically as possible though what they will be doing, without wasting undue energy or causing fatigue.
Vibration massage (not massage guns) also has excellent benefits. Time is important so the best solution would be to a professional standard machine like our Ultimate Quad Head Massager that is capable of massaging a larger area at once. A good routine would be to apply 30-60 seconds to each of the major muscle groups you will be using.
Conventional massage will be worthwhile, but not be the best use of your time. While it has some benefits it takes longer and they are not as great as those of a dynamic warm up or vibration.
Stretching exercises do help lengthen your muscles, but if you overdo it they will reduce performance and increase your risk of joint injuries. If you do stretch limit the stretch to normal movements of your joints.
Clinical trials show practically no benefits from using foam rollers, while non professionally supervised real world usage is likely to produces even worse. These are not recommended.
As discussed above percussion massagers are an attempt to combine vibration massage and conventional massage. The reality is that they deliver far less therapeutic vibration without any redeeming compensation. The massage gun marketing material will tell you how beneficial vibration is, so just get a proper vibration massager. For more info please see How to choose a massager

DrGraeme massagers were originally built by Dr Graeme for use in his clinic, and to prescribe to his patients for additional self use at home. Now these are used by colleagues and other professionals for similar purposes. If you are a professional and wish to know more about this therapy, or possibly get a sample massager to trial please check out our practitioner page.
