Advice Pool - The Truth About Stretching
A three year old study about stretching is being cited in many articles today, and the conclusions reached by some writers may be harmful to the muscle, ligaments and joints of your athletes.
Is stretching before practice harmful?
Stretching before athletic training and general fitness improvement exercise is being made out to be a time-waster, not needed, and even harmful. This is not true. In fact, there's a recent study that evaluates all the research on stretching, and the study concludes:

It's a creditable study designed to show the occurrence lower limb injury on a group of young army recruits.

The statement, "Fitness may be an important, modifiable risk factor" is very important. It simply means that age, weight, and conditioning of the study subjects may be an important factor in preventing or facilitating the injuries experienced in this study.

Researchers show that athletes should not perform prolonged static stretching before the big game or a key practice session because this slows muscle activation for around an hour afterwards, (Reduced strength after passive stretch of the human plantar flexors, 2000, Fowles).

Gains in flexibility are dependent on the “duration” of stretch-hold position, and researchers show the best “stretch-hold position” (for time-spent) to increase flexibility is 30 seconds (The effect of time on static stretch on the flexibility of the hamstring muscles, 1994, Bandy).

Keep in mind there are important lessons in these studies, but the studies apply to a specific age group (over 65, and ages 21 – 45,) and a specific physical condition (tight hamstrings). If we apply the results of a study with these variables to young athletes, we may be wrong.

nable to conclude (as I have for training purposes) that static stretching away from practice is an effective strategic for athletes with tight hamstrings, this study doesn’t specifically prove that point. It’s clearly a mistake to take the findings of one study and create an absolute fact. Look at the whole body of research about a topic before making a life-changing training decision.

2. Dynamic stretching (arm swings, hip rotations, knee rotations) will aid in the pre-competition, pre-practice warm-up process by increasing flexion in the joints and increasing body temperature. This method is preferred before athletic competition.
3. Static stretching can be used as part of a warm-up for training. However, static stretching will slightly slow down athletes for an hour afterwards so examine training goals. Early in the season, static stretching before practice may be a wise strategy.
Th
y and representatives from various regulatory agencies are working out to design the regulatory requirements for manufacture and sale of combination products
best way to improve overall flexibility is static stretching with 30-second stretch-holds performed away from events requiring peak performance. Personally, I recommend to athletes attending my Speed Camp to use a 10-minute static stretching routine targeting hamstrings, Achilles, hip flexors and quads four days a week.
