Flexibility, Mobility and Stretching in Football | David Behm & Bernardo Requena – FSI Talks #11

Flexibility and mobility are key components of athletic performance in football. Proper stretching strategies can improve movement efficiency, support injury prevention and help players maintain optimal physical condition throughout the season.

In episode 11 of FSI Talks, Bernardo Requena, co-founder and sporting director of FSI Training, speaks with Professor David Behm. Behm is a renowned researcher and one of the leading international experts in flexibility training.

Together they explore the differences between flexibility and mobility, the most effective stretching techniques, and how these methods can be applied in football training environments.

Flexibility vs Mobility in Football

One of the key topics discussed in the episode is the distinction between flexibility and mobility, two concepts that are often confused in sports training.

Flexibility generally refers to the passive ability of a muscle and surrounding tissues to lengthen. It is typically assessed through passive tests that measure the maximum range of motion available in a joint.

Mobility, on the other hand, refers to the ability to actively move through a range of motion during sport-specific actions such as sprinting, turning or kicking.

“Both concepts are complementary and necessary to optimize performance,” explains David Behm.

While flexibility focuses on the maximum possible range of motion, mobility is more related to how effectively athletes can use that range during real sporting movements.

Main Stretching Techniques Used in Football

During the discussion, Behm explains several stretching methods commonly used in football training programs.

• Static stretching: Holding a muscle in an elongated position for a specific period of time. It is often used outside of intense training sessions.
• Dynamic stretching: Controlled movements that take joints through their full range of motion, such as leg swings or arm circles.
• Ballistic stretching: Rapid and explosive movements that push muscles beyond their typical range. This method requires proper preparation.
• PNF stretching (Proprioceptive Neuromuscular Facilitation): Combines muscle contractions and relaxation phases to increase range of motion.

Each method serves a different purpose within training, and selecting the appropriate one depends on the timing within the session and the athlete’s individual needs.

Mobility Exercises Commonly Used in Football

Mobility routines are frequently integrated into warm-ups to prepare players for the physical demands of training and competition.

Typical exercises used by professional teams include:

• Jumping and plyometric movements
• Lateral movements and agility drills
• High-knee running and coordination exercises

These drills help activate the neuromuscular system while increasing joint mobility and preparing muscles for explosive actions.

Benefits of Flexibility Training in Football

Flexibility training can provide several benefits for football players, particularly when integrated strategically into training programs.

• Improved performance: Greater range of motion can enhance stride length and movement efficiency.
• Reduced injury risk: Properly applied stretching may reduce the likelihood of muscle and tendon injuries.

Research suggests that short-duration static stretching performed before activity (less than sixty seconds per muscle group) may contribute to injury prevention in explosive sports such as football.

How to Implement Stretching for Injury Prevention

Behm recommends incorporating flexibility work at two key moments within an athlete’s routine.

Before training or matches, short static stretches can be combined with dynamic stretching and mobility exercises to prepare the body for movement.

Outside the field, longer stretching sessions lasting sixty to one hundred twenty seconds per muscle group can help maintain tissue elasticity and support recovery.

When players experience limitations in range of motion due to chronic issues, additional tools may be useful.

• Foam rollers
• Vibration massage devices
• Assisted stretching techniques

These strategies can complement traditional stretching methods and introduce greater variety into recovery and flexibility routines.

Flexibility Across Different Stages of Life

Another topic discussed in the episode is how flexibility changes with age.

Behm explains that as athletes grow older, elastic fibers within connective tissues gradually become replaced by collagen. This process can reduce tissue elasticity and limit range of motion.

However, consistent physical activity can slow this decline. Veteran athletes often maintain impressive levels of flexibility thanks to regular training habits.

In younger players, especially during adolescence, maintaining flexibility routines becomes particularly important.

Limited flexibility during growth phases has been associated with a higher incidence of muscle injuries, making preventive training essential during this stage of development.

An Integrated Approach to Flexibility and Mobility

The episode concludes by emphasizing the importance of adopting an integrated approach to flexibility training.

Combining different stretching techniques and mobility strategies helps avoid training plateaus and promotes optimal physical adaptation.

With guidance from experts such as David Behm, coaches and performance professionals can apply evidence-based methods to improve movement quality, enhance performance and reduce injury risk in football players.
