Re: The Truth About . . Fitness

A brief summary of some of the points the programme covered.

The 10,000 steps fad

Lots of people have heard of and try to follow the 10,000 steps a day target. The programme looked to see if there were ways to achieve better results in less time.

They set one group (A) of people on the basic 10,000 steps a day regime.

They set another group (B) doing 10 min brisk walks which they had to do 3 times a day, so 30 mins in total.

Group A generally found it hard to squeeze 10,000 steps into their lives each day and had to do some unusual things to get there.

Group B found it easy to fit 3 x 10m brisk walks into their daily routines.

The 3 x 10m walks proved to be much more worthwhile for fitness because of the more moderate effort involved.


HIT - High Intensity Training

Nothing much new here I suspect but they were again looking to see whether there were ways to get the maximum amount of fitness benefit from a minimum amount of exercise time.

They tested some candidates aerobic stats using exercise equipment and oxygen masks linked to computers.

They then set the candidates off on a regime of
2 x 20 second high intensity bursts on an exercise cycle

They had to do this 3 times a week

They showed that as you sprint cycle, the stored sugars in the body are metabolised for use. The candidate's glycogen store levels fell. Sugar depletion was shown to be about 24%.

The programme also stated that the body responds to such exercise by creating resilient genes to strengthen body areas which included the heart.

By comparison the programme said that you would have to go on a 45 min run/jog to get the same fitness benefit as these few 20 sec intensive bursts on a cycle.

After a few weeks on the regime all candidates improved aerobic fitness levels by on average 11%.


HIT Regime At Home

For those without an exercise cycle or any similar equipment they provided a home exercise regime which involved just 5 mins of exercise with a small warm up first thus:

First, jog lightly on the spot for a min to warm up

Then

1) Do as many star jumps as possible in 1 min

brief recovery

2) Do as many squats as possible in 1 min

brief recovery

3) Do 1 min of static sprinting, i.e. running on the spot as fast as possible

brief recovery

4) Another minute of squats

brief recovery

5) Another minute of star jumps


Just 5 mins in total ! Max benefit for minimum exercise time


Heavy Weights vs Light Weights

They tested heavy weights against light weights to see if there was any benefit.

Candidates had to do arm lifts with heavy dumbbells with one arm until they could do no more. Then do the same with the other arm but using a light dumbbell.

They did the same with leg weight machines.

Turns out that it makes no difference whether you use heavy or light weights in terms of fitness but candidates preferred the heavier weights because the exercises were over much quicker than with the lighter weights.

Running vs Walking

They wanted to test whether running or walking put more pressure and stress on your joints.

Long story made short, the answer was obvious. Running put more impact stress on the joints than walking, however there was a crucial BUT

Walking saw the impact pressure on the joints lasting twice as long as running. With running the foot was in contact with the ground for much less time than walking. As a result running was deemed to be the better exercise and the programme stated that the notions that running destroys your joints and gives you arthritis was a myth.

In fact the shorter lived but more intensive impact from running resulted in cartilage being constantly compressed and relaxed which increased its ability to use oxygen.

There were some other areas explored too

Worth a watch.

Set your machine to record on BBC 4 at 2:20am in the morning

No point watching it now. You've told us all about it.
The question is...why have you?

Re: The Truth About . . Fitness

Another potentially interesting programme coming to BBC 4 this Thursday 10th Jan at 22:00.

"Why Are We Getting So Fat?"

"Dr Giles Yeo investigates obesity in the UK. Many people believe that if people could just eat less, the obesity problem would be solved, but this may be harder than it sounds"

Re: The Truth About . . Fitness

Many people are ignorant about looking after themselves. They see keeping fit as hard work and want a quick, sweet fix as far as food is concerned.
Educate people on how to eat and exercise properly and it may be possible. Trouble is though, many folk are basically ignorant and can't be bothered. They just 'hope for the best' and that's basically having no thought for their health. They will learn the hard way when they succumb to many health-related issues as they grow older.
Anybody with a modicum of common sense doesn't need a doctor or a TV programme to tell them that.

Re: The Truth About . . Fitness

I was also wondering why you watched it Realist, when you keep telling us that Diet and Exercise is a waste of time.

Bizarre comment.

It's a thread highlighting a programme exploring fitness and common fitness fads, posted in the Exercise and Fitness section of the forum!

Why would it wind anyone up?!
