Unleashing Your Inner Sprinter: Boosting Stamina with Running Intervals

Boosting Stamina with Running Intervals

Gone are the days when long, monotonous runs dominated the cardio world. Enter interval running, a dynamic mix of short, high-intensity bursts followed by lower-intensity recovery periods. Interval running, an integral part of interval training, amplifies your running stamina and redefines your running experience. So, let’s dive deeper into the mechanics and advantages of this invigorating workout strategy.

How Does Interval Running Boost Stamina?

The principle of interval running is based on the concept of VO2 max, essentially the maximum oxygen consumption rate during incremental exercise. This technique involves pushing your body towards its VO2 max during intense sprints, followed by lower-intensity recovery periods to allow for rest and recuperation.

By alternating between high-intensity and low-intensity running, you force your body to adapt to anaerobic and aerobic exercises. This adaptation results in an enhanced ability to tolerate lactic acid build-up, improved cardiovascular capacity, and a high VO2 max. These enhancements directly contribute to increased stamina, as stamina is the ability to maintain prolonged physical effort.

Research supports this notion. A study published in the Journal of Strength and Conditioning Research concluded that high-intensity interval training (HIIT), which includes exercises like interval running, effectively improves endurance performance and VO2 max in trained runners.

The Four Types of Interval Training

Before lacing up your running shoes, it’s crucial to understand the different types of interval training. Each type serves a unique purpose and contributes to boosting your stamina:

  1. High-Intensity Interval Training (HIIT):  These workouts involve short bursts of high-intensity exercise, often reaching up to 90% of your maximum heart rate, followed by extended rest periods. HIIT is especially effective for increasing your metabolic rate and burning fat.
  2. Fartlek Training:  Fartlek, a Swedish term meaning “speed play,” combines continuous and interval training. During a Fartlek run, you would intersperse fast and easy-paced running periods.
  3. Tabata Training:  Named after the Japanese scientist Izumi Tabata, this training method involves 20 seconds of maximum intensity exercise followed by 10 seconds of rest, repeated eight times for four minutes. Tabata training is a short yet highly effective way to improve aerobic and anaerobic systems.
  4. Sprint Interval Training (SIT):  This method involves full-effort sprints for short periods (20 to 30 seconds) followed by more extended rest periods. SIT is perfect for improving speed and power.

Bringing Interval Running Into Your Routine

Starting Slow:

  1. If you’re new to interval running, start with a basic high-intensity interval workout.
  2. Warm up with a gentle 5-10 minute jog, then run at a higher intensity for one minute, followed by a two-minute recovery period.
  3. Repeat this cycle 5-10 times, and conclude with a 5-minute cooldown jog.

Experimenting with Variations:  Once comfortable with basic interval running, explore other types, such as Fartlek and Tabata. Remember, the key is gradually increasing intensity and decreasing rest times as your stamina improves.

Consistency is Key: For visible improvements in stamina, consistency in interval running is crucial. Aim for two to three weekly interval running sessions, regular steady-state runs, and strength training exercises.


Interval running is a game-changer in the realm of endurance running. Not only does it ramp up your stamina, but it also introduces an element of excitement and variety to your runs, making them more enjoyable. Now that you’re armed with this knowledge, it’s time to hit the track and get your heart pumping!
