Fitness Research Spotlight

Survey suggest that a lack of results from exercise interferes with our motivation to keep working out. In fact, most adults (65%) say they would be willing to exercise more often if they saw results faster. At the same time, almost one in three (32%) struggle to identify workout options that meet them where they are, that accommodate their very low or very high fitness levels. A solution to getting faster results AND scaling to diverse fitness levels is to use interval training. Specifically, use intervals that reaches high intensities. Intensity is a relative experience, so by seeking CHALLENGE in your workouts with interval training, you can try the workouts that benefit every athlete.

Why athletes use intervals?

Athletes and their coaches know that to build bodies that can handle the rigors of their event, they must practice in ways that challenge their current fitness level. To push our physical abilities beyond where they are today, we have to be willing to try hard, to engage fully, at least for a short period of time. Enter interval training: The fastest way to hit those intensity targets, albeit for very short periods of time!

Interval training involves short periods of challenging intensities, with recovery periods in between them. A typical workout often includes four to twelve intervals, depending on the intensity reached. Sprint intensity is all-out, as much as you can give. Sprint intensity workouts are usually limited to ten or fewer intervals because they are quite potent, and the interval period is always very short.

Athletes use sprint intensity intervals because it they create workouts that are fast, effective, and it can engage you like nothing else.

What is Sprint 8?

Sprint 8 involves “sprint intensity” intervals. This describes an all-out level of effort that lasts only 30 seconds, followed by 90-second recovery periods. This pattern of high- and low-intensity intervals is repeated eight times, though beginners may opt for just one to four sprint intensity intervals. With an additional two to three minutes to warm up and to cool down, the entire workout takes just 20 minutes to complete. The results you see below are all achieved by sprint intensity interval training. 

Results-driven, time-efficient:

The best part about interval training is that a full workout is relatively short. Intervals that reach higher intensities have been used by many dedicated athletes for improved athletic performance.

Athletes reap benefits from interval training:

  • Field hockey players who tried sprint intensity intervals were able to achieve faster running velocities compared to their typical training. Another positive change is that they enhanced their ability to extract oxygen during exercise, which occurs when energy-producing mitochondria grow or multiply within muscle cells. The authors remarked that this approach provides excellent aerobic adaptations while minimizing risk of injury, because joint-friendly options can be used (like ellipticals, ascent trainers or indoor cycles).
  • An Olympic-level windsurfer showed similar improvements using a rower for sprint intensity intervals. Just three weeks of regular sprint intensity interval training boosted the athlete’s peak power output. The authors conclude that sprint interval training benefitted several measured of work capacity, including maximal aerobic performance.
  • In elite badminton players, sprint intensity intervals rapidly improve aerobic capacity. An eight-week intervention using sprint intensity intervals significantly enhanced fitness and endurance. Indoor cycles were used for interval sessions several times a week. Male players improved their fitness by almost 6% and female players by about 9%. (These fitness improvements are impressive considering their high level of baseline fitness!) The researchers state that intervals reaching sprint intensities offer a “time-efficient training alternative” suitable for athletes in highly demanding sports.

Not just for athletes…

Interval training benefits all of us!

It may seem like intervals are reserved for the most fit among us. But instead, interval training is a tool that anyone can use to gain fitness, no matter your starting point!

“Am I too unfit / too old/ too ____  to try it?” 

As with any change to your movement routines, it is a good idea to ask your doctor for personalized guidance.

There is ample support for intervals that reach higher intensities, at levels where you are temporarily out of breath and feel the burn in working muscles. Supportive studies includes a range of individuals, such as those with low baseline fitness levels. They also test this exercise strategy in those who are older, and even those who have never exercised regularly before. 

Results from trying interval training:

  • Lifelong sedentary men in their 60s were invited to try interval training as part of a study. After three months, their outcomes from trying intervals that reached high intensities revealed several areas of improvement: 
    • Improved physical functioning and general health
    • Increased health-related quality of life
    • Better aerobic capacity and fitness

Bringing interval training to you!

It takes courage to try something new. And it is not easy to commit to challenging workouts, even when they are short in duration and promise impressive results! That’s why Treo puts our members in control of how they move, with hundreds of on-demand fitness options (equipment and non-equipment-based). 

New to our fitness lineup are a variety of interval workouts. We include short options at just 5 or 10-minutes as well as the full-length 20 minute Sprint 8! Results are possible, one workout at a time. Email us at info@treowellness.com to learn how your organization can gain access!
