Interesting blogs

Here are links to some interesting articles I have come across recently:

The Hindu Push Up – a variation on the old classic

Eating quickly is associated with overeating – and overeating associated with…

The human body is built for distance – on a hot day a human can outrun a horse over a marathon

Moderate amounts of protein best for building muscle – over 30g may be a waste of your time

Baseball – head first slide is quicker – and more likely to result in your head hitting baseman’s/catcher’s knees!

 

 

How to hold your breath for longer

October 31, 2009

Disclaimer: This is for reading entertainment only. Do not try any of this yourself!

I was a little skeptical after reading Tim Ferris’ blog that I would be able to hold my breath for a significantly longer period of time after simply completing a few breathing exercises.

How wrong I was.

Within a period of less than 10mins I went from being able to hold my breath for 1:02 to 3:31. During the purging (see definition below), and after about 1:30 of holding my breath, my fingers were seriously tingling, and then from about 3:00 on I felt like I was going to pass out…but I made it. Beating Harry Houdinis personal best, but falling 2 seconds short of Tim Ferris.

You can read the whole post here (including videos), or just read the protocol (breathing exercises) he used below:

Definitions:

Deep breathing: “Deep breathing” involves taking a big breath in through the mouth, holding for one second, and then exhaling for 10 seconds through your mouth through your almost-closed mouth with tongue pressed against your lower teeth. It should be a hissing exhalation and make a “tsssssss…” sound. All breathing and exercises are performed though the mouth.

Purging: “Purging” involves a strong exhalation as if you were trying to blow a toy sailboat across a pool, followed by a big but faster inhalation. David’s cheeks were puffed out as he demonstrated the exhalation (imagine the big bad wolf blowing the pigs’ homes down). Be careful not to heave or rock back and forth, which wastes oxygen. Keep as still as possible.

Semi-purging: Breathing between the above two. More forceful than deep breathing but less forceful than full purging. Used for recovering after each time trial.

The Steps:

1:30 deep breathing
1:15 purging (if you feel like you’re going to pass out, do it less intensely)

Hold breath for target 1:30, no more
After 1:30:
Take 3 semi-purge breaths

1:30 deep breathing
1:30 purging

Hold breath for target 2:30, no more
After 2:30
Take 3 semi-purge breaths

2:00 deep breathing
1:45 purging

Hold breath for as long as possible
After exhalation:
Take 3-10 hard semi-purge breaths until your recover

Nanny State & Obesity Prevention

October 7, 2009

In south Los Angeles legislation to minimise big fast food stores is mis-directed, with the area actually having less of these stores per-capita than other areas of LA. The probable problem here  is large number of smaller fast food outlets.

I have heard a similar argument before regarding Fast Food vs Fine Dining. An often ignored fact is that the typical Fine Dining restaurant in your area produces meals every day that are as bad, if not worse than many Fast Food outlets. The reason one is condoned and the other celebrated is because of their absolute effect on the community. Simply put: more people eat at McDonald’s than any Fine Dining restaurant. In this regard it seems some Fast Food Outlets are really just a victim of their own success.

Food choice

September 27, 2009

What determines what food choices you make at the supermarket?

For most it comes down to taste and price, with nutritional value “a little bit lower down” the list.

The challenge as I see it, is to make tasty & cheap foods that are good for you…

Outside Workouts

September 4, 2009

One of the downsides to Personal Training in New Zealand is the climate. Being able to get outside more often -especially in winter -  adds not only enjoyment, but crucial variety, fresh air, and vitamin D.

But it is not only the (winter) climate, there is also a lack of equipment. It is real a downer for people wanting to exercise in the outdoors by themselves, as you find yourself having to use children playgrounds (and getting very strange, angry looks from parents).

Group training sessions have proved to be a good society-wide health initiative. Unfortunately due to the climate I doubt they would pass the “Wet Wednesday Test” in New Zealand – ie if it was a cold, wet Wednesday would you go to an outside free training session?

Cities should build workout areas/circuits in popular exercising areas. I am not talking about building Muscle Beach, but rather a few pieces of equipment spread around popular exercising areas that are totally free to use. It would be interesting to see any studies on the cost/benefit of building such circuits, like I recently saw in Aotea Lagoon. I would imagine they are positive.

I will watch the launch of YikeBike with interest.

Not sure I am prepared to fork out 100 EURO just yet though…
