Exercise. It gets the blood pumping and the muscles going. It energises you and it tires you out. And sometimes, after a good workout, you wake up feeling all sorts of stiffness in muscles you didnt know you had. So what causes this?
Let’s start by looking at something called: Muscle Hypertrophy:
This is when your muscles increase in size as they get stronger. Due to:
- Mechanical tension
- Metabolic stress
- Muscle damage
This muscle damage is what can cause Delayed Onset Muscle Soreness (DOMS). So while muscle damage is not an essential aspect of hypertrophy, it is a sign that you are on the right track to building muscle… albeit a painful sign.
DOMS is a distinct muscle pain that is caused by overloading the muscles through heavy or unaccustomed activities. It can range in severity and timing and is characterised by a feeling of being sore, achy, weak and generally quite “pap”. Often it develops overnight and one will wake up feeling this soreness. Unfortunately DOMS can often deter people from exercising as they feel they are getting hurt, however this is not the case and DOMS is a natural reaction that does subside.
There is one thing that is certain in life, and that is that each and every one of us ages a little bit, every day. In your 20’s and 30’s ageing is probably not even noticed, as life is so busy and exciting. By the time you are 40, some hints start creeping in, but these are minor symptoms of ageing – slight crow’s feet around your eyes, or somewhat less vigour and energy compared to when you were in your youth, for example. When you are in your mid 50’s all of a sudden, out of nowhere, you have developed several aches and pains, body stiffness, and you may have to take a handful of pills every day for a list of chronic conditions that you have somehow managed to accumulate. What about when you are 70 or 80 years old, then what? Considering that life expectancy has increased substantially, and that people are living much longer than a few decades ago, it’s certainly becoming a realistic question to ask, “When I am in my mid-80’s, how will I have aged and how functional will I be?”
Ageing seems to be relative, as some people approach ageing with the attitude of “70 is the new 60”. How old are you really? Your biological age is simply how long you have been alive, but a much more important question is, “What is your body age?” In other words, how well does your body work and function? Is your body old, stiff, weak, unable to carry out functional activities because of pain, disease, chronic conditions and poor lifestyle habits? Or are you mobile, functional, able and fit? Although we are all getting “older” every day, exercise has been shown to challenge the concept of biological ageing, as it significantly reduces the risk of disease development and other chronic conditions that are so often associated with old age.
