Why does delayed onsite muscle soreness vary so much?

In my previous article, I explained what delayed onset muscle soreness (DOMS) is.

So does DOMS mean my workouts are more productive?  

You don’t need to experience DOMS to know your work outs are productive or building muscle.  The reason is that although DOMS is general indicator of the degree of muscle tissue damage it various significantly from person to person and therefore it is not a reliable indicator.

So why does DOMS vary so much?

The short answer is because no two bodies are identical, just like our personalities our bodies are unique. Below is a list of the factors that influence this variation:

  1. Athletic condition, age & the muscle system
  2. Structural damage to muscle tissue and tendons
  3. Inflammatory response

The young are more susceptible to DOMS because their bodies as not yet developed enough to handle intense workouts.  While the old are more susceptible because of the hormonal changes associated with ageing and the decreased recover rate.  Structural damage to muscle tissue and tendons contributes to the body’s inflammatory response.  This inflammatory response created swelling and pain.

  • Soul Food

    Last week I talked about having a spiritual connection, soul food is what helps increase our spiritual connection. Soul food is spiritual nourishment, it is anything that simply uplifts or inspires us.  One universal source of spiritual uplift is to bring more beauty into life, whether this is through exploring nature, being creative or simply appreciating art.  Beautifying your home or garden is an easy way to feel more spiritually nourished.  Other common soul foods include enjoying the wonder of children or exquisite music.  Making time to catch the sunrise or sunset can seem like a huge challenge in our busy lives yet it never fails to leave is feeling more uplifted.  Similarly climbing to the top of a hill or mountain is worth the effort to see the view which can often uplift us.   Another, key spiritual nourishment is to simply stop, and remember you are a “human being” not a “human doing”, so stop and take the time and space to simply be. We often feel down in the dumps or depleted when we have gotten to bogged down with responsibility, and “doing” while forgetting how to play, sing, dance and make things with our own hands.  That is when its time to stop and nourish yourself with soul food.   Remember soul food can literally be  anything that nurtures us and makes life feel it’s worth living. Identifying your soul food and feeding it to yourself increases your spiritual connection which is profoundly healing and nurturing and probably one of the best form of preventative medicine you can give yourself. If you would like to improve your spiritual connection try exploring the following

    • What lifts my spirit and inspires me?  Can I spend more time doing what inspires me?
    • Who lifts my spirit and inspires me?  Can I spend more time with people like this?
    • Are there any places that inspire me?  How often would I like to visit them?
       

  • More Mindfulness Exercises

    In my previous post, How to be mindful, I described a mindful breathing exercise.  Now I want to share with you more mindfulness exercises. 1. Mindful Observation Choose a natural object, plant, flower or cloud in the sky.  Simply focus solely on it for a minute or two.  Visually explore it and allow yourself to be consumed by its presence. 2. Mindful Listening Listen to a piece of music you have never heard before.  You could re-turn your radio to a new station or download a new track to your ipod.  The idea is to listen, to become fully entwined within the composition without preconception or judgement of the genre, artist, lyrics or instrumentation. 3. Mindful Appreciation The point of this exercise is to simply give thanks and appreciate the seemingly insignificant things in life; the things that support your existence but rarely get a second thought in our desire for bigger and better things.  All you have to do is notice 5 things in your daily life that go unappreciated. Once you have your 5 things, then consider

    • the benefit they bring to your life and the lives of others
    • what life would be like without these things
    With regular practice of mindfulness services, rather than being on autopilot, we keep our mind rooted in the present moment and deal with life's challenges in a clear-minded & calm way.
