comment Stretching muscles while they are engaged
AIS is closer to ballistic type of stretching, you may also be looking for PNF stretching. Here's a decent Honors thesis on the various types of stretching with their impact on power, injuries, etc. digitalcommons.liberty.edu/cgi/…

comment Caffeine and creatine
More likely you got the benefits of the coffee, and previous creatine supplementation. You will not feel immediate effects from ingested creatine.

comment What's the proper tension for the belt on a treadmill?
Unfortunately, I don't think there is an exchange site that would work for this. You should be able to go to the manufacturers website and download the instructions/troubleshooting, or they may have support forums available.

This is a nutrition question, and as such, off topic for the site. I encourage you to read the welcome pages to help you formulate better questions for the site format.

comment What's the proper tension for the belt on a treadmill?
It doesn't matter what kind of treadmill it is, the question is off topic. Gear used during exercise is on topic if you are asking about it as part of an exercise program, not how to repair it.

comment Why is my left foot going numb when I run? (when it was not a problem previously)
Shoes wear out. You shouldn't really run in the exact same pair day after day. Ideally you will have 2-4 pairs that you rotate through, and depending on your gait/weight/running frequency and the type of shoe, the shoes will need replacing every 200-500 miles (Total on pair). If you wear them around for everyday, that will also shorten the lifespan.

comment What's the proper tension for the belt on a treadmill?
I'm voting to close this question as off-topic because it's about how to adjust some unidentified, unknown treadmill.

comment Breathing out during swimming freestyle
@andrewb - Very true. I was a distance specialist, so I was more approaching it from that. But you are correct, 50m will breath once (if that), and 100m 3-4 times in the race. Good point.

comment How do I deal with episodic insomnia during puberty
There are people on here that will say anything as well. Internet advice is worth what you pay for it. Go see a doctor.

comment Is there a website / service with publicly accessible database of workouts?
Possibly something in here: wlinfo.com/resource.htm and bodybuilding.com/fun/workoutdatabase.htm (Neither has an API that I can see, however.)

comment What happens to your muscles when you stop working out for several years?
Well said, +1. Also, this (the cited study) is another reason being voiced by anti doping proponents in sport, in that benefits while doping stay for long after the person has stopped.

@GeoffHutchison - We are saying the same thing in different ways. :)

comment Redline heart rate running
@GeoffHutchison - I have seen HR's spike in the low 210's in the last couple years and I am 48. If he is exercising comfortably at 179, he is probably well under (25+ bpm) his theoretical maximum. And while you have a larger heart, that doesn't mean that your maximum is ~ 175. Unless you've done a clinical stress test, no way to really accurately tell. All it means is that for equivalent workloads, you generally have a lower HR than the guy next to you with a smaller hear.

comment Breathing out during swimming freestyle
@bharal - Yes. If you hold your breath and then exhale and inhale, you can create symptoms of hyperventilating. A breath every 3 is fine. Just like other exercise, unless you hold your breath while running. :p

comment What does it mean to “isometrically contract” some muscles?
@BKE - Forced exhalation would, but not because of the diaphragm. In that case, you are contracting intracostal (rib) muscles, abs, etc. causing the ribcage and abdomen to compress. The diaphragm just relaxes. I'm not familiar with the book of the OP, but isometric contractions have been recommended to help build both strength and muscle density in many different regimens.

comment What does it mean to “isometrically contract” some muscles?
No, exhalation is the relaxation phase of the diaphragm. Nothing is contracting (Although you can control the rate of relaxation, or it will be handled automatically). Generally, inhalation is an isotonic contraction, the diaphragm contracts causing a vacuum which in turn expands the lungs and causes inspiration.

comment What are the detrimental effects of over exercising?
See Michaels answer. If you are running 2 hours a day, you NEED carbs for fuel. Stop following a fad diet, and eat real food, including carbs, the lower the processing involved the better.
