I would like to have an explanation of why aerobic activities,like jogging, help one man to keep fit while anaerobic activities, like lifting weight, contribute little effort.
What the heck does "surPISSED" mean????dextercioby said:I never heard of anaerobic activities... You mean anaerobic bacteria...?What do they have to do with lifiting weights...?:surpissed:
Actually, when you're talking about running, anaerobic means your body is using oxygen faster than it can physically take it in. This is why a typical person can only sprint for about 100 meters or so. If you're running at a pace you can sustain, it's aerobic.dextercioby said:I never heard of anaerobic activities...
Unless of course you're content with the level you've achieved and just want to just maintain that.Zantra said:Also as someone already said you can't stick with one routine for very long. Vary the routine- if you lift weights, gradually increase the load as you feel your muscles becoming accustomed to that weight. Otherwise your body will "plateau" and you will stop noticing improvement.

Likewise ... helps quite a bit in doing aerobic ones. I'm under the impression that people either do very ineffective aerobic workouts (no one wants to run, 'cos it's hard and a pain in the butt ) even though the basis of all fitness is that you need to have at least some aerobic stamina to be able to do anything (and working at a 50-60% HR level for 30 mins is a really low level aerobic workout, this is what you usually see people doing at gyms). But flexibility is even more underrated.franznietzsche said:Really?
I always go the opposite. But i'm tall skinny guy. running works.
Yeah, way more actually. The exertion curve which is a some sort of a measure of power you put in the workout is way steeper for anaerobic ones, and anaerobic ones continue to burn after the workout is over. The problem and source of most misconceptions is that unless you're really fit - do anaerobic workouts and even beyond regularly and really train for them - you're unable to keep the pace for the required periods of time for it to be beneficial in any respects + the recovery from them takes that long of a period of time that it backfires (the way many men seem to exercise ... do 2 jogs / week "spitting blood" during the runs, in the end not doing much good at all).primarygun said:Isn't that anaerobic activities help us burn more fats than aerobic activities?
My text book said the latter one burns more

Anaerobic activities are usually performed over a short period of time - e.g. running 400 m or 1 mile (1.61 km) as fast as possible (this is running, not weight lifting). Try running 400 m in less the one minute (60 sec), or for a challenge under 50 seconds (basically run as fast as possible until you collapse - you might want to wear pads and head protection). Aerobic activities burn fat and glucose, while anaerobic activities use a process called 'glycolysis'. See bold items and links below.primarygun said:Isn't that anaerobic activities help us burn more fats than aerobic activities?
Fuel Utilization During Exercise, Aerobic and Anaerobic Metabolism, Control of Muscle Protein Metabolism/AnabolismLike engines, muscles do work and require fuel. The body supplies a fuel called ATP to the muscles. This allows the muscles to do their work of contracting. Because it is very important that muscles always have access to this fuel, the body has adapted different ways to make this fuel. It can use:
* an aerobic pathway, which requires oxygen to make fuel, or
* an anaerobic pathway, which makes fuel without oxygen.
During normal activity the blood supply to a muscle can provide all of the fuel (fatty acids and glucose) to a muscle using aerobic metabolism. This holds true under moderate exercise, as well. Moving through your day to day activities you fuel your muscles in this way. This is true during walking, gardening, and bike riding, too. However, when the activity level reaches about 80 percent of the maximum possible, aerobic metabolism can no longer meet the energy needs of the muscles. Now anaerobic metabolism kicks in and begins to provide large amounts of energy to the muscles. Heavy weight lifting, sprinting or any rapid burst of hard exercise will trigger this energy pathway. Anaerobic reactions are not efficient. They produce large amounts of a byproduct called lactic acid (which comes from pyruvic acid). Lactic acid build-up contributes to muscle fatigue and rapid breathing.
In order to help our bodies be their strongest, we should do exercise which requires both kinds of fuel metabolism. Aerobic exercise keeps our hearts healthy. An easy way to detect aerobic exercise is when we have an increased heart rate, but we can still speak without gasping for breath. Hiking, biking, cross country skiing, and dancing are types of aerobic exercise. Think of long and slow exercise when you think aerobic. Most of your exercise should be of this type to develop hear lung fitness and improve your body's fat burning ability.
Anaerobic exercise helps us increase our muscle strength and stay ready for quick bursts of speed. Activities done with enough force to cause shortness of breath and burning muscles are examples. Think of short and fast when you think of anaerobic. from Anaerobic Metabolism - Energy Without Oxygen
Oooh... that's not natural... i've been running for a few years now and i've never had that happen before.PerennialII said:(the way many men seem to exercise ... do 2 jogs / week "spitting blood" during the runs, in the end not doing much good at all).
might have been a "slightly" inflated comment but I think you got the picture . But actually pretty realistic if you're doing for example long uphills etc.motai said:Oooh... that's not natural... i've been running for a few years now and i've never had that happen before.
