Today's training tip comes from Stuart McGill:
Not a Good Morning
Full spine bending first thing in the morning is a great way to damage your back. You're taller when you wake up in the morning than when you go to bed at night. This is because the discs suck up water while you sleep. After rising, just walking around and using the muscles during the day compress your spine and the fluid is squeezed out, decreasing the anular tensions in the disc. So, when you wake up the extra height in the discs are analogous to a water balloon ready to burst. If you bend, you build up much higher stresses in the disc. In fact, the stresses are three times higher than when you perform the same bend two or three hours later. So, heavy bending exercises, good mornings or sit-ups for example, performed first thing in the morning is not a good idea.
Well, Mr. McGill needs to step out of the lab once in a while.
Find me a person who trains heavy regularly, and does so directly after rising, and I will show you a teenager who does so for 10 days before burnout.
Reality check:
People wake.
People BEND to get out of bed.
People STRETCH to move.
People then, (at least the overwhelming MAJORITY), SHOWER. -And most with hot water.
All of these things fix Mr McGill's issues.
Follow this sequence with breakfast, then a heavy lifting routine 1 1/2 hours later. -THAT is the best.
Do people do it this way? Not normally. People work, go to school, take care of family, etc. -They put their health last.
In any case, following the morning routine IS the best for strength and cardio because it trains the body to do its hard work and then maintain functionality after, rather than trying to explode on the scene after an exhausting day.
If any such heart attack link COULD exist, it would be linked to late training schedules. A late training time such as in evening hours causes a chemically predispositioned metabolism to try to reverse a sleep mode, and turn it into hyperactivity mode. This can be correllated to a min-PTSD effect if you will. Therefore, long term workouts such as that could overstress the heart, nervous system, and mental functions.
I hope something I posted helps.
