What are Static Stretches

As physical therapists we are frequently asked about stretching exercises. Static stretching exercises are those stretches that you are told to hold for so many seconds and do so many times a day. When you think of stretching, it is usually this type of stretching that immediately comes to mind.

To perform this type of stretching exercise one must elongate the muscles as tolerated and that position is then held for a particular length of time. The time a stretch is held is determined by your age, pre existing conditions, activity level, and any injuries. For more information on how long to hold a static stretch click here.

In most cases it is a safe way to elongate soft tissues for those just beginning an exercise program and sedentary individuals.

What are the Benefits?

  • Static stretching has shown, through research, to improve flexibility and joint range of motion
  • This mode of stretching prevents the soft tissues from absorbing high amounts of energy over a short period of time as does ballistic stretching.
  • This slow form of stretching will not facilitate a strong relfex response and so helps in relaxation.
  • This form of stretching can alleviate muscle soreness.
  • Stretching in a static manner is thought to be the safest way to stretch and therefore is most appropriate for a large percentage of the population(1).
  • Stretching statically can be done individually, unlike PNF or assisted stretching and no special knowledge or handling is required.

Why This Form of Stretching?

 A good rule of thumb is, in order to maintain mobility you should take each joint through its full range of motion once a day. In the clinic we see the results of immobilization as patients are taken out of casts, and people try to become more active after a period of injury. Soft tissues will inherently shorten unless moved. That's the nature of viscoelastic substances. "If you don't use, you lose it".

When Should I Stretch?

  I have had patients come to me that have never stretched because their personal trainer told them it would hurt their workout. A few studies that have been misinterpreted are changing the way we work out. Static stretches are not necessarily "bad stretches".

A player of any sport with tight hamstrings should undertake a stretching workout because these players are more prone to hamstring strains. This type of program should take place daily, at least three times a day. Studies show that for individuals under forty that 30 second holds are sufficient(2) (there is no benefit to holding longer than 30 seconds in this age group), younger individuals can get away with 15 second stretches.(3) People over 70 benefit from static stretches held 60 seconds more than 30 seconds. (4) Stretches should be painfree and not overly uncomfortable. If you experience pain during a stretch, see your physical therapist prior to starting a stretching program.

 Stretching is only a small part of  an appropriate pre-participation warm up. In some cases, too much static stretching can actually predispose an athlete to injury. 

General consensus now is that pre-participation static stretching is not beneficial for optimum performance. Your warm up is best to consist of active exercises to increase circulation with sport specific movements. This type of activity causes increased temperature in the muscles used which improves elasticity and therefore flexibility. Depending on your sport, specific dynamic or ballistic stretching may be more appropriate.

After a workout is the best time to perform static stretches. Muscles are warm, ligaments and joints are more elastic, but if you suffer from muscular imbalances or are interested in maintaining or increasing your flexibility, static stretches should be done daily.

Injury Prevention

People have come to expect a lot from a few stretching exercises. Claims of injury prevention and improved performance are unfounded, but that doesn't mean static stretches don't have their place in a training or fitness regimen. Pre-activity stretching commonly done by athletes thinking they can help their performance and reduce injuries are coming under scrutiny (5,6,7). There is literature that suggests there is a reduction in strength and power following static stretches. (8,9) The length of time that strength and power are affected and the mechanisms causing these losses are still being investigated.

Static stretches were emphasized years ago amongst gymnasts, track and field participants, and skaters. In these particular sports one requires a great deal of flexibility to perform the tasks of the sport. In sports such as hockey (goalies excluded), rugby, or football, this extreme flexibility is not necessary. Every sport has a certain set of skills that requires a given flexibility. Exceeding this flexibility is no guarantee of injury prevention; however, if one doesn't have the adequate flexibility necessary to perform the sport, they are definitely prone to injury.

A study in 2000 looked at male army recruits to determine if static streches would reduce the risk of injuries.(10) It was determined that static stretching didn't  result in a meaningful reduction in the rate of injury.

In this study the greatest predictor of injury was a poor aerobic fitness level. It is theorized that no benefit results from static stretches because of the following reasons:

  • Certain activities don't benefit from increased flexibility.
  • Stretching doesn't effect muscle elasticity during eccentric activity which is when most injuries occur.
  • Stretching may result in microtrauma to the muscle predisposing it to injury.
  • An increase in stretch tolerance after a static stretch may mask pain that would normally result in muscle guarding during an injurious activity.
