Sprint intervals or straight jogging...

[turnedthecorner]

what burns more fat and boosts your metabolism?

I am currently doing sprint intervals on the treadmill for about 25 mins. 1 min sprint, one minute standing on the side not running at all, then hop on to treadmill and sprint again for one minute, etc...

Is this better than jogging at a good pace or the same or not as good? I had a trainer once tell me it'd shape me up pretty damned fast if I did it a lot.

Sprint Intervals burn more fat then steady state jogging..

What is your speed on the intervals.. for instance I do sprints at 8 mph for 1 min then i recover by walking at 3.6 mph for 2 min.. Somedays I switch things up by doing sprints for 40 secs and recovering for 60 secs... when you are done doing sprints for 25 minutes you should be so exhausted that the thought of doing another one is just to exhausting to think about..

Wish I knew what speed it was. It is a treadmill speed of 11, whatever that translates too. Not sure? It's different on every make and model. Would it indicate somewhere on the panel what speed I am running at?

Glad to hear this as I rather enjoy doing it, it's less boring than straight jogging.

Actually, sprint intervals burn no more fat than jogging. Actually, sprints burn carbohydrates more than fat, while jogging burns more fat than carbohydrates. In the long run it makes no difference however as fat will be lost depending of what deficit there is in caloric intake. Aerobic exercise is what boost your overall heart and lung fitness. Jogging is aeorbic exercise. Sprints are anaerobic. Treadmills typically have their speeds in MPH. 11 should be 11mph if it is a commercial treadmill. That would be a fast sprint speed. My thoughts are as long as one is active, that is a good thing mentally and physically.

I'll bet when you do sprints, you will find that your overall time exercising will go down, and when you run distance, you will be increasingly able to run for longer and longer times.
The sprints will help you gain speed.
The only point that I would make is try not to run too long or too fast too soon. That’s a good way to hurt yourself, and you will not be able to run at all for a while.

Yes and know... It depends on the intensity of the sprint vs the duration of a steady jog.
Here's a good way to look at it.

Compare average heart rate from sprint workout to average heart rate from sustained run.

The one with the higher average heart rate will have burned more calories.

For most people looking to burn fat; any sustained workout averaging over or around 100 beats per minute is what they should go for. As you get in better cardio shape you will have to work harder to obtain the same rate of bury.

Also keep in mind that the aerobic heart rate zone (around 120) burns fat more efficiently than higher heart rate zones.

Sprinting will do a better job of toning muscle.

Sounds like your doing great.... 30-40 min 3x per week should be all you need to get noticeable results and build a great cardio base.

I like intervals because they are more fun for me than steady state cardio, but they are something I would do more than 2 or 3 times a week - especially if you are weight training legs. Your best bet would be to combine intervals with steady state stuff throught the week otherwise they will burn you out.

Back when I swam, sprint intervals really helped with increasing my overall speed and fitness. I used to mix it up, some steady state mixed with intervals. If you have a spare moment to Google, check out fast and slow twitch muscle fibres.

It totally depends upon the sprint intervals. Comparing this with jogging is not a solution i think. If you go with the exercise you like the most will be more beneficial to you than to compare with any exercise.

Exactly, from my understanding of sprint work or anaerobic training(without oxygen) your body tends to burn avaible energy ie the carbs and/or various sugars in the bloodstream for energy.

When you are out of breath from sprint work your body really doesn't have the time and/or oxygen to breakdown fat for energy. Fat is like a lot of other things that burn: they burn better in the presence of heat and oxygen. When you jog you have more oxygen in your system since you are not out of breath. That's why the rule of thumb run no faster than you can talk is excellent one.

The sprint work still has benefit and is excellent for the heart and other muscles. Sprint work helps increase you intensity which in turn helps increase the results/benefits of your workouts. Sprint work probably creates more fat burning during rest and recovery than an aroebic workout.
