Exercise Intensity Vs. Duration

Exercise Intensity Vs. Duration You've probably heard that High Intensity Interval Training (HIIT) can produce results similar to a much longer period of steady state moderate intensity effort. A study published in the Journal of Undergraduate Kinesiology Research compared a half hour of moderate intensity exercise to a pair of 15 minute moderate intensity sessions separated by three and a half hours.

Eight young healthy adults ran on a treadmill at 70% of their maximum capacity for 30-minutes continuously or for two 15 minute sessions separated by 3 hours of rest. Researchers calculated that the steady state session burned about 12.1 calories per minute while the split session only burned 11.3 calories per minute. That's a difference of 20.6 calories over the cumulative half hour of exercise.

True Strength Moment: This study suggests that elevating your effort with an HIIT style of training that alternates between 30 seconds of all out effort and a minute of low intensity jogging for a total of 15 minutes might be a better alternative for those days when you're pressed for time. If time isn't a factor, stick around and finish the entire workout before calling it a day. Here's a tip for burning more fat: Lift weights before performing cardio.
