How to Improve Flexibility

Jun 26, 2014 | by AIF

In order to have a well-rounded approach to your fitness, it’s important to include flexibility in your training, says Meghan Jarvis, Course Crusader and Exercise Therapy Program Coach QLD.

Benefits of Flexibility

There are many benefits to improving flexibility, such as:

  • It reduces the risk of injury during sport, exercise and activities of daily living due to increased functional range of movement (ROM).
  • Stretching assists with posture by helping realign skeletal structures and address muscular imbalances.
  • It improves the ROM and physical function in joint synovial fluid, which is an important factor in countering the loss in range of motion that occurs with aging and degenerative joint disease.
  • It contributes to a reduction in emotional and psychological stressors by releasing tension both mentally and within the exercised muscle.

Flexibility Tests

There are many different flexibility tests with three of the most common being:

  • Supine hamstring test
  • Hip flexor/Thomas test
  • Shoulder flexion test

Flexibility testing should be completed as part of the initial consultation to give fitness professionals a better understanding of their client’s abilities, and what exercises need to be incorporated or avoided to assist in making fitness gains.

Improving Flexibility

Although there are a variety of stretching techniques, the three primary types that you should use to improve flexibility are dynamic, static and proprioceptive neuromuscular facilitation (PNF).

To perform dynamic stretching, take the joint through its full ROM at the beginning of exercise or activity. This helps prepare the muscles and joints, however it is less effective for improving flexibility.

Static stretching involves passively or actively taking a specific joint or set of joints through a ROM to a mild point of tension.

Lastly, PNF stretching has been shown to yield the greatest change in range of motion, which presents short-term benefit. This form of stretching will have the most profound effect on your client’s flexibility.

By incorporating flexibility training into programming, you will be a step closer to excelling in your fitness goals, avoiding injury and experiencing a better quality of life.
