Protect Your Body While Exercising

Joe Fleming explains how to protect your body best when exercising.

We get it. You want to achieve that dream physique. But if you do not consider ways to protect your body while doing your exercises, you might end up doing your body more harm than good. In your eagerness to reach your fitness goal, you might end up neglecting specific safety measures when training.

Body's Response to Exercise

First, you need to understand the physiologic changes that happen to your body when exercising.

  • Muscles - Muscle cells need a higher energy level when you are exercising. To produce this energy in the form of ATP, the blood vessels in your muscles dilate, increasing the blood flow and the oxygen delivery to the muscle cells. During intense exercises, your body's available oxygen might no longer be enough to sustain this demand. You might begin to breathe faster to compensate for your body's oxygen needs. Anaerobic glycolysis could take over to supply your body with energy. Since lactic acid is the by-product of anaerobic metabolism, you might experience muscle pain and fatigue. Your muscles suffer from minor cuts and tears during training, and they grow and develop during the restoration or healing stage.
  • Joints -
  • Your joints take on additional weights during exercise. Too much can lead to injuries and tears of the adjacent ligaments and tendons. Your joints are your shock absorbers.
  • Lungs - Since your muscles need energy, your lungs work harder to supply your cells with the oxygen that it needs to generate ATP. When this demand increases, your lungs compensate by breathing faster and deeper. Your diaphragm is the primary muscle for breathing. During intense exercise routines, your diaphragm could get exhausted, leading to spasms. When this happens, you might experience a side stitch.
  • Heart - To answer your body's increasing oxygen demand, your heart would pump faster to deliver oxygenated blood to the cells that need it. The release of lactic acid and adrenaline into the blood increases the heart rate. When you exercise regularly, the cardiovascular system becomes more efficient to pump and to deliver oxygen to the cells. This is why, with regular training, your resting heart rate could be lower than an average person's.
  • Brain - During exercise, your sympathetic response overpowers your parasympathetic. This response causes dilation of the blood vessels in your skeletal muscles and constriction in your stomach organs. This happens because your muscles need more oxygenated blood during exercise than your visceral organs. More blood also reaches the brain, thanks to the faster and harder pumping of the heart, and could contribute to better brain function.
  • Skin - When your hypothalamus detects an increase in your core body temperature, it taps the sweat glands in your skin to produce sweat. As your body sweats and your sweat evaporates, heat is also transferred to the environment, regulating your body's core temperature. The blood vessels in your skin also dilate, leading to more blood flow to the skin. This would give your skin a reddish tint. As the blood vessels get nearer to the surface of the skin, heat is easily transferred into the air, aiding in your body's thermoregulation.

How to Protect Your Body While Exercising

The last thing you want to happen in your fitness journey is an injury, which could pull you back several steps behind. Here are some tips that you could follow to ensure that your body is protected while you are doing your routines:

  1. Warm-up and cooldown - Warming up prepare your muscles and joints for the actual workout. Do not subject your body to training without proper warm-up because this can lead to unnecessary body pains or, in severe cases, muscle strains and injuries.
  2. Stay hydrated and eat right - During exercise, you lose a lot of fluids through sweating. During intense training, you also lose electrolytes. Replenish your electrolyte and water stores through hydration. Dehydrated muscles are more prone to injuries. Also, treat your body right by giving it the proper nutrition that it needs to heal and recover from your training session.
  3. Build-up - Do not jump headfirst to that complicated training routine. Start slowly and gradually build up the intensity until your muscles and body adapts. Overtraining could lead to muscle and joint injuries.
  4. Take a hint - When you are feeling unusually tired and sore all over, skip your training for the day. Rest. It means that your body has not recovered yet. It is vital to give your body adequate time to rest and restore its functions. Failure to do so could lead to overuse injury. Take a hint: Skip your training for the day when you feel exhausted and sore all over.
  5. Dress properly - This is important, especially if you are doing your training or workout outside of the gym, where you are more prone to environmental elements. Take notice if it will be a hot or a cold day and dress appropriately. Ensure that the shoes you are wearing have enough cushion to prevent joint injuries. When your knees feel sore or painful, using knee braces could offer some support. Check out this website for more information.

Always remember to protect your body when you are doing exercise. If you treat your body right, it will also give you the results you want.
