CHANGES IN TRAINING LOAD AND RUNNING-RELATED INJURIES

A study published on the end of 2018 questioned if the change in the training load could increase the risk of injuries. The article is a systematic review which is the highest level of scientific evidence. Have been reviewed several articles but only 4 were qualitative good to be considered in the study.

The Conclusion of the study were:

3/4 studies found that:

  • Sudden increase in running distance between 2 weeks
  • A non-specific recent change in one or more training variables (velocity, distance, volume, frequency)

Lead toward an increased injury risk

In contrast the Fourth study found:

  • no difference in injury risk when comparing two intervention groups

Therefore, there is not enough evidence to state that a change in the training load will increase the risk of injuries among runners.

Although is worthwhile to underline that an excessive progression in training load can increase the risk of injuries.

The main problem is to understand and investigate what means EXCESSIVE, this can vary a lot among novice, amateurs and professionals.

In effect another important revelation in the study is:

  • The 10% rule used from several runners and coaches is not supported from any evidence, finding no differences between an increase 10-29%.

Let’s do an example:

  1. Novice: run 10km per week
  2. Amateurs: run 30km per week
  3. Professionals: run 100km per week

An increase of 10% of weekly increased would be:

  1. Novice: 1km
  2. Amateurs: 3km
  3. Professionals: 10km

Now imagine doing so over a month period, it’s easy to understand that the absolute value among them would be different. A Novice would increase roughly 5km over one month and a professional would increase roughly 50km.

We can understand that if for the novice can be a good progression, for the professional is something unimaginable.

Individualise the training load is probably the best answer.

Because the factors to consider are many, just to name a few:

  • Age
  • BMI
  • Nutrition and supplementation
  • General Fitness
  • Presence of Pathologies
  • Previous or current injuries
  • Training environment
  • Muscles weakness

Just few examples:

Let’s consider two novices:

1 person has BMI 22(healthy)

1 person has BMI 32(obese)

Can we expect the same progression? The answer is certain no

Same if we consider two amateurs where one is 65 years old and the other 20years old.

Muscles weakness, a recent study published in January 2018 showed that an insufficient strength of the deep core musculature may increase a runner’s risk of developing LBP.

In fact, with complete deep core muscle weakness, peak anterior shear loading increased on all lumbar vertebrae (up to 19%), Additionally, compressive spinal loading increased on the upper lumbar vertebrae (up to 15%).

Is then worthy to consider it? Absolutely yes.

A good advice would be to have a regular check up with your physiotherapist considering all the possible variables, trying to develop the best training load which suits for you.

Your physiotherapist can also assess the presence of restriction in the joints motion, the presence of muscles weakness or any imbalance which may lead to an injury.

In this way you will have an inclusive picture of the situation, also will be addressed the needed of any home or gym exercises which you can implement in your running and progressive loading program.

COVID-19 NOTICE

 

5 STAR CLINIC LTD has put in place several measures to assess and manage the risk of Covid-19 transmission.
Be aware that is not possible to completely eliminate this risk and that a face to face consultation will increase
the likelihood of you contracting COVID-19.

Full information here: 5 STAR CLINIC LTD COVID-19 POLICY

 

BEFORE BOOKING A FACE TO FACE APPOINTMENT:

We are following the CSP chart “Virtual first”, therefore you will be required to have
a Video Consultation at first(15min FREE), where a Triage questionnaire will be also administered.

At the end of the Video Consultation, we will decide if is deemed necessary
a FACE to FACE appointment or if we need to proceed with a virtual consultation.

    Please DO NOT ATTEND:

    1. If you have you been in close contact (<1m for at least 15 minutes without any protection) with a confirmed case of COVD-19
    2. If are you in the list of clinically extremely vulnerable people, click here: VULNERABLE GROUP
    3. If either you or one of your household has been ill in the last two weeks
    4. If you are suffering from any of the below:
      • Shortness of breath.
      • New persistent cough.
      • Fever over 38 degrees C.
      • Change or loss of taste/smell.

      SUMMARY OF MEASURE IN PLACE TO REDUCED THE RISK OF COVID-19 TRANSMISSION:

    • We follow hand and hygiene practices throughout the meeting.
    • We provide hand sanitizing facilities and a surgical mask (Type IIR)
    • We minimise contact time closer than 2 metres and for less than 15 minutes
    • We keep at least 15min gap between patient for environment decontamination
    • We provide adequate air changes (average of 15min/hour with 4 to 6 air changes)
    • We provide cleaning and decontamination of equipment, surface and areas
      between each patient
    • Throughout the clinic are placed relevant posters to raise awareness and help in
      managing the risk of transmission
    • We follow safe removal and disposal of PPE in accordance with infection prevention
      and control during Covid-19 document
    • In the waiting area, a maximum of 2 people at a time at a distance>2m will be allowed.
      The patients know where to sit, as in the sitting area 2 chairs are provided only.
    • We follow Respiratory and cough hygiene – ‘Catch it, bin it, kill it’. Disposable, single-use tissues
      should be used to cover the nose and mouth when sneezing, coughing or wiping and blowing the nose,
      used tissues should be disposed of promptly in the nearest waste bin tissues. To be followed from hand hygiene.
    • We are only using disposable or washable material (such as couch covers, paper tissue, couch/pillow etc.)
      The therapist will be wearing PPE in line with government guidelines (disposable gloves, plastic apron,
      surgical mask (Type IIR), eye protection or Visor will be used if at risk of droplets)

      WHAT DO WE REQUIRE FROM YOU?

    • To arrive on time for your appointment.
    • To do not arrive before or late to avoid crowding in the waiting area.
    • On arrival will be taken a contactless temperature reading.
    • To wear a surgical type mask during the waiting and the treatment*.
      a mask will need to be purchased at the clinic if you do not bring one.
    • To wash or clean the hands with hand sanitizer on the arrival and before.
      leaving and whenever may be needed to reduce the risk of contamination.
    • Please try not to use the toilet if possible and DO NOT USE self-service area.
    • On each face to face consultation, you will be required to fill and sign a Triage questionnaire.
    • Maintain 2 metres separation where possible, for instance, during the subjective examination.
    • To avoid cash payments preferably using contactless payments as much as possible), or online transfers.
    • To come alone unless strictly necessary to be accompanied. After entered the building, the companion will be allowed
      to enter only if strictly necessary (see below chaperone/translator).On the other hand, will be asked to leave and wait in the car.
    • In the case of chaperone/ translator is required will be asked to stay 2m apart of all the time from everyone, also they will need
      to complete a pre-screening questionnaire.
    • Follow Respiratory and cough hygiene – ‘Catch it, bin it, kill it’. Disposable, single-use tissues should be used to cover the nose
      and mouth when sneezing, coughing or wiping and blowing the nose, used tissues should be disposed of promptly in the nearest
      waste bin tissues. To be followed from hand hygiene.
    • Confirm contact details for the patient and each person accompanying the patient and inform them that these details may be used
      for contact tracing if required.
    • If possible, an electronic signature will be used on all of the document, if not a signature with a clean pen, after the hands have
      been sanitized

 

* Patient use of face masks

In clinical areas, common waiting areas or during face to face treatments patients is required to wear a surgical face mask.
The aim of this is to minimise the dispersal of respiratory secretions and reduce environmental contamination.
A surgical face mask should not be worn by patients if there is potential for their clinical care to be compromised (such as when receiving oxygen therapy).
