Interval Running Boosts Cardiovascular Fitness Over Steady Jogging

Interval running, a form of high-intensity interval training (HIIT), offers a time-efficient way to gain the extensive benefits of running, including disease prevention, mental health improvement, and slowing biological aging. This exercise method alternates bursts of intense running with periods of rest or low-intensity activity, exemplified by techniques such as the '10-20-30 method' and the Swedish 'fartlek' method, which incorporate sprints into jogging. Research indicates that interval running significantly enhances cardiovascular fitness, boosts metabolism, and improves body composition, with particularly notable benefits for overweight and obese individuals. Due to its adaptable nature, interval running can be integrated easily into regular workout routines to maximize health benefits in a shorter time frame. Despite the well-known benefits of running, about 31% of people are insufficiently active, primarily citing lack of time as a barrier, which interval running can help overcome. This approach is gaining recognition and recommendation from health researchers and fitness experts for revitalizing workouts effectively.
