Do you have over-training syndrome
BY JULIE SEAMERWEDNESDAY, OCTOBER 22, 2008
Are you guilty of over-training? Would you be aware of the warning signs, even if you were?
The symptoms of this syndrome are generally grouped under four categories:
- psychological – depression, apathy, emotional instability
- physiological – changes in blood pressure and resting heart rate, also heart rate changes during exercise and in recovery
- biomechanical – factors including depressed muscle glycogen and depressed free testosterone
- immunological – susceptibility to illness1
Signs that you might be over-training include feeling washed-out, tired, moody and drained, mild leg-soreness or general aches and pains, headaches, sore joints, a sudden drop in performance, insomnia and headaches 2-3.
One of the bigger problems with over-training is the increased susceptibility to injury. Is it worth it?
There exists a simple effective way to test potential Over-training Syndrome known as the Orthostatic Heart Rate Test which monitors Heart Rate Variability (HRV). This is something you can do yourself, at home:
- lay down and rest in a comfortable position for 10minutes at the same time every day (morning is best)
- record your heart rate in beats per minute (bpm) using a heart-rate monitor or by counting your pulse for 15 seconds then multiplying by 4.
- Stand up
- After 15 seconds take a second heart rate
- After 90 seconds have passed take a third heart rate
- After 120 seconds take a fourth heart rate
It is said that a well rested athlete/person will show a consistent heart rate between measurements. Those with a marked increase (10 bpm or more) in the 120 second post-standing measurement are on the verge of over-training 4.
Exercise alone can increase stress on the body in certain ways, even when we aren't over-training. For instance a study in the United States concluded that oxidative stress and free radical damage are enhanced during bouts of strenuous, heavy and physical exercise 5. This is reason to ensure supplementation of antioxidants to protect the body.
It should also be kept in mind that exercise, particularly at high levels can deplete immune response. A study conducted on 150 runners who took part in a marathon race were studied (against people who didn't run). Symptoms of Upper Respiratory Tract Infection occurred in more than one third of runners compared to less than 15% of controls and were most common in those who achieved faster race times (indicating that the harder you push, the more toll on the body's immune system) 6.
