Stretching Can Hurt Speed Training



Here are some of the dynamic exercises in the video (lunge walk, high knee, Frankenstein, lateral lunge walk, leg swings forward and side to side, butt kicks, and curtsy walk).

Flexibility training is perhaps the most undervalued component of speed training. While recent and ongoing debates question its role in injury prevention, athletes can still gain much from a stretching regime. Flexibility is defined as the range of motion about joint surrounding muscles during a passive movement. Passive movement refers to gravity or partner assisting the movement instead of actual muscle contraction to activate the stretch. This article is dedicated to explaining why flexibility is important in developing speed. In addition, we will look at the difference types of stretching and when to use them, when they are beneficial, and when they are detrimental in an athlete’s speed workout. We also will discuss how to stretch and develop a stretching program for a speed workout.

Flexibility may reduce injury and increase range of motion ROM. There are factors that also affect flexibility:

Age: flexibility particularly extensibility decreases with age
Gender: Females exhibit greater ROM
Activity: those that are active are more flexible
Internal tissue temperature: temperature influences ROM which is why it is important to warm up before stretching. Athletes should take 10-15 minutes after their workout for static stretching and should concentrate at least 30 seconds per muscle group.
Injury: scar tissue from previous injury affects ROM in a joint

A more flexible athlete equals a more mobile athlete. A good flexibility regiment enhances movement on the court and field and causes athletes to have a greater ease of movement as well as increases the body’s awareness and promote relaxation. For instance, take the hip flexor muscles which are one of the most important muscle groups for running. The hip flexor is located above the thigh and affects the stride length and stride frequency (which is the most important) of athletes. Increasing flexibility in the hip flexor results in an increase in stride length. Athletes in different sports have varying flexibility needs in order to avoid injuries. For example, sprinter type athletes (soccer players, football players, rugby players, basketball players, and baseball players) have a much larger movement and ROM requirement for their sport in comparison to an endurance/ distance runner. As a result, the sprinters would need more of a flexibility regiment than the distance runners. In addition, even though flexibility is important, it can vary between individuals.


Static stretching is the most common form of stretching and is a more traditional way to improve flexibility. Static stretching just prior to an event may be detrimental to actual performance due to the nature of the stretch and hold component. It is performed with no bouncing during the stretch and there is no emphasis on speed. The athlete holds the stretch for at least 30 seconds. It should be incorporated into the cool-down phase of a training session. Static stretches are often simple to learn and perform and require little effort.

However, dynamic stretching is more beneficial because it mimics the actual movements that will be engaged in the events and activities. It should be done after a proper warm up prior to training. Dynamic flexibility is performing stretches or movements that would simulate the actual movement required of the activity. These movements are performed at similar speed to the movement and differ from ballistic stretches in that they do not involve any bouncing or jerky movements.

Static Stretches
Hamstring Stretch
Sit on the ground with both legs straight out in front of you.
Bend the left leg and place the sole of the left foot alongside the knee of the right leg.
Allow the left leg to lie relaxed on the ground.
Bend forward keeping the back straight.
You will feel the stretch in the hamstring of the right leg.
Repeat with the other leg.

Calf Stretch
Stand tall with one leg in front of the other, hands flat and at shoulder height against a wall.
Ease your back leg further away from the wall, keeping it straight and press the heel firmly into the floor.
Keep your hips facing the wall and the rear leg and spine in a straight line.
You will feel the stretch in the calf of the rear leg.
Repeat with the other leg.

Hip and Thigh Stretch
Stand tall with you feet approximately two shoulder widths apart.
Turn the feet and face to the right.
Bend the right leg so that the right thigh is parallel with the ground and the right lower leg is vertical.
Gradually lower the body.
Keep you back straight and use the arms to balance.
You will feel the stretch along the front of the left thigh and along the hamstrings of the right leg.
Repeat by turning and facing to the left.

Adductor Stretch
Stand tall with you feet approximately two shoulder widths apart.
Bend the right leg and lower the body.
Keep you back straight and use the arms to balance.
You will feel the stretch in the left leg adductor.
Repeat with the left leg.

Groin Stretch
Sit with tall posture.
Ease both of your feet up towards your body and place the soles of your feet together, allowing your knees to come up and out to the side.
