What is Sprint Interval Training (SIT)?
Most of us have heard of high intensity interval training, better known as HIIT workouts. However, there is another form of training that is also commonly used to boost cardiovascular fitness. This other form is called sprint interval training (SIT). So what is the difference and why does it matter?
HIIT involves alternating between short bursts of intense exercise and periods of lower-intensity recovery. It often incorporates a variety of exercises like jumping, running, or strength movements. HIIT can be used in sprint intervals such as sprinting for 20-30 seconds at a high speed on the treadmill, followed by a short period of either rest of walking speed. HIIT usually incorporates “near max” effort, which equates to roughly 80-100% of your max heart rate.
SIT focuses exclusively on short, max-effort sprints followed by longer recovery periods, which vary between rest or very low-intensity activity. A commonly research SIT protocol includes 4-6 30 second maximum effort sprints with a 4 minute recovery window.
While both improve cardiovascular health and increase metabolism, SIT is more intense and time-efficient, requiring maximal effort during sprints. HIIT allows for a broader range of exercises and slightly more recovery time, making it more versatile for different fitness levels. One study found that both HIIT and SIT improved anthropometric measurements and cardiovascular fitness in health women, however those who performed the SIT protocol had greater reductions in the skinfold measurements.
Overview of the Health Benefits of Sprinting
Everyone knows the major health benefits of exercising in general. But what about the benefits of sprinting?
Sprinting has been shown to not only improve cardiovascular health, but can help aid in weight loss, improve mental focus and clarity, and so much more. But specifically, what exactly does sprinting help with?
Sprinting helps with:
- Leaner body composition
- Increasing oxidative capacity
- Improving metabolic health
- Improving brain health and releases endorphins
- Boosting mood
…and so much more! This is a testament to sprinting’s role not just in fitness, but in enhancing our overall wellbeing.
How Sprinting Improves Fitness
Sprinting can help counteract the effects of aging by stimulating muscle growth. With each passing decade, we lose 3-8% of our muscle mass. Keeping muscle mass at optimal levels is important as we age. This study states that in one 30 second sprint on a cycle ergometer, there is a marked increase in serum growth hormone release. Growth hormone is an important naturally-occurring hormone in the body which helps build bones and muscles. It is greatly influenced with exercise. Thus, you can help support your muscle mass (and growth hormone levels) by incorporating sprinting into your workout regimen.
Fast-twitch muscle fibers, encouraged by rapid bursts of sprinting, are crucial for quick movements and high power outputs. Peak power output increases with sprint training, which is the highest level of force your body can generate in the shortest amount of time. Various studies have shown improvements in VO2max, varying from 11.5% up to 23.4%.
Despite losing muscle mass and slowed reaction times as we age, sprinting offers a powerful counteraction to these aging effects. By engaging in high-intensity interval training (HIIT) and focusing on sprinting, we can stimulate muscle growth and improve agility, fundamentally enhancing our physical fitness.
Sprinting Benefits for Heart Health
Cardiovascular health dramatically improves when incorporating sprinting into your fitness regimen. Your body’s oxygen usage optimizes, enabling your body to take in more air and utilize it more efficiently during physical tasks.
Your resting heart rate and blood pressure can decrease, which can also lower your risk of heart disease. You may also notice real-world benefits, including reduced fatigue and better endurance when performing tasks.
Lowering your heart disease risk and improving cardiovascular fitness also helps with improving metabolic health.

Mental and Metabolic Rewards
The beauty of sprinting lies in its simplicity and its profound impact on our physiology, promoting lean body mass and improving cardiovascular health. The rapid bursts of speed trigger a cascade of metabolic control adjustments within the body. It can help optimize blood glucose regulation by aiding in improving insulin sensitivity and insulin resistance.
The benefits of sprinting extend beyond the physical. Engaging in regular sprinting sessions acts as a catalyst for stress reduction, regulates mood, and can help stave off depression. Regular participation in sprinting is associated with improved cognitive function, focus, and enhanced memory. This study found that brain-derived neurotrophic factor (BDNF) concentrations were significantly higher in sprinters compared to sedentary individuals. BDNF helps neurons grow and survive, which plays an important role in memory, learning, and behavior.
Sprinting isn’t just about speed. It’s a pathway to a stronger, more resilient you, both mentally and metabolically.
The Versatility of Sprint Training
One of the most enticing aspects of integrating sprinting into your fitness routine is its sheer versatility. Unlike other forms of physical fitness that might require a trip to the gym or specialized equipment, sprinting can be performed just about anywhere. Whether it’s at a park or your neighborhood street, you can harness the incredible benefits of sprinting with no more than a pair of good running shoes.
Moreover, the after-burn effect associated with high-intensity training like sprinting is something of a marvel in the realm of exercise science. This phenomenon ensures that you continue to burn calories long after your workout has ended. It’s the bolstering of cardiovascular health and enhancement of lean body mass that makes sprinting not just a simple exercise, but a powerful tool for body composition and overall health.
Building Speed and Power: A Closer Look at Muscle Fibers
Within our muscles are what we call fast-twitch and slow-twitch muscle fibers. Sprinting activates the powerful fast-twitch muscle fibers. These muscle fibers are what give us explosive speed and power and it is something that can be trained over time. In fact, they have to be trained. The body is good at storing energy and keeping energy expenditure to a minimum. You have to train your body to use these fast-twitch muscle fibers, as they tend to fatigue very quickly.
Yet, as you sprint, you send a profound message across your system, urging it to adapt, to toughen up against the demands. This isn’t just about getting faster; it’s a full-scale renovation project aimed at your cellular infrastructure. Suddenly, you’re not just working out; you’re architecting a leaner, more agile version of yourself, capable of peak power output and unmatched endurance. And beyond the physical, you’re igniting the metabolic furnace, elevating your metabolism and enhancing glucose regulation – all by embracing the sheer intensity of sprinting.
Replicating Sprint Intensity Indoors
When the weather turns, or you find yourself unable to hit the open road for a sprint, there’s no need to worry. You can still harness the incredible benefits of sprinting, right from the comfort of your gym or home. Treadmills are a great resource to supplement your outdoor sprinting workouts. Treadmills provide an intense, high-velocity burst that replicate the demand sprinting places on your body.
Regardless if you are running indoors on a treadmill or outdoors at the park, you will be training your fast-twitch muscle fibers to build speed and power. You body won’t know the difference between a sprinting workout indoors vs. outdoors. You get all of the added benefits of sprinting outside along with sprinting on the treadmill. You’ll get a boost in metabolism as your body continues to burn calories up to 2 hours after your sprinting session, as well as the cognitive benefits.
Embracing a Healthier Lifestyle
If you’ve ever considered the leap into high-intensity training or pondered how to elevate your physical fitness, embracing the power of sprinting might just be the pivotal change needed for a healthier, more vigorous lifestyle. The benefits of sprinting extend far beyond simple endurance or fat reduction. This dynamic form of high-intensity training magnifies your cardiovascular health, enhances oxidative capacity, and encourages lean body mass production, all while engaging those crucial fast-twitch muscle fibers.
Engaging in sprinting exercises doesn’t just sculpt a more toned body or boost your metabolic control. It also incorporates agility, fortifies your cognitive health, and, through stress reduction, nurtures your mental well-being. By incorporating sprinting into our routines, we’re pursuing a holistic enhancement of our agility, endurance, and overall wellbeing.
