I like to exercise regularly, however, I usually stick to the same routine; fourty five minutes doing cardio and around a half hour doing strength training, but is that good? After doing some research on it, I realized I wasn't improving my strength and enurance, I was maintaining it. I've never been the type of person whose been into sprints or short interval training but apparently if I want to continue improving the shape I'm in, I should. http://www.msnbc.msn.com/id/8407349/
The whole point of the article was to prove that practicing short interval training is more effective in improving one's strength and endurance as opposed to a normal hour a day routine. I read up on a study that was performed on two groups of people; one group practiced intense sprint interval training for around 30 minutes each session and did this 3 times a week. The other group went on doing there usual 5 hour a week exercises. The results proved the theory correct, the grop who practiced the short interval training improved there endurance by 50% and also improved their ability to use oxygen. The group who did their normal routine showed no change. If you want to improve your fitness, you want to use all your muscle fibers which froms tears in the fibers that allow you to continue improving. On the other hand, doing slow and long training, you only use some of your muscle fibers which gives you little to no improvement, just consistency.
Although, the short intervals are a good method to make improvements in strength or endurance, it's also a lot more difficult. Proving this study further, coaches for teams such as football always have their team participate in regular sprints to up their physical strength and endurance, whereas people who like to maintain their physical fitness level have a usual slow and longer routine to stay seady and constant. Depending on the force put upon the muscle fibers determines whether or not there will be a change. The more intense the force, the more deterioration in the fibers which is a good thing if it results in improvment, as long as you don't overdo it.

Improving your muscular strength and endurance helps you maintain or increase bone mass, reduce body fat, reduce blood pressure and control your blood glucose. Strength training is the fastest way to improve muscle strength and endurance. It's also important to breathe normally during these exercises.

When I do cardio training I usually don't do the regular 20-30 minutes treadmill or elliptical. I'll usually incorporate the short sprints of energy that you were explaining. This high intensity training I found out to be great on increasing many aspects of my body overall.
