Before each of these sessions max heart rate, you’ll want to keep tabs on all kinds of stats, like distance covered, pace per mile (or interval), Before each of these sessions, hours slept… We could go on.
But at the end of the day, there’s one measurement that stands out for having a huge influence on performance enhancement: your VO2 max.
All About VO2 Max and What It Means
“VO2 max is a measure of the amount of oxygen your body can use while running or the maximum rate at which we can race a middle- or long-distance race,” Interval Workouts for Every Experience Level Shoes & Gear. It’s a number that denotes what volume of oxygen (in milliliters per kilogram of bodyweight per minute) that your body delivers during activity. Simply put, it’s a gauge of your aerobic capacity.
If you’re interested in knowing your exact number, there are a few ways to measure it. The first, and most accurate, is to have it tested in a performance lab. That’s also pricey and the most uncomfortable, as you’ll have to endure a tough session at an all-out effort on a treadmill with a mask strapped to your face.
Many new smartwatches also offer VO2 max approximations; some Garmin watches, for example, estimate your number based on data including heart rate and running pace, plus info about your Before each of these sessions.
The easiest way to approximate your VO2 max is to use a simple equation, based on your max and resting heart rates: VO2 max = 15x (HR max/resting HR)
All that being said, you can train to improve your VO2 max, and your overall running performance, without calculating your exact number. Here’s how.
The Best Types of Workouts to Boost VO2 Max
When it comes to improving your VO2 max, your genes play a huge role. However, “with good old-fashioned hard work, it’s possible to improve your VO2 max,” says Benson.
Getting faster by way of VO2 max work is all about efficiency. “The higher your VO2 max, the faster or more efficiently you’ll be able to finish a race or training run—as your body moves the oxygen in the most effective manner,” says April Gatlin, ACE-certified personal trainer, master trainer, and coach for STRIDE Fitness.
The best way to train your body to do just that is by regularly tackling intervals—both interval runs and HIIT sessions incorporating strength moves. The good news: While you need to do intervals regularly, it shouldn’t take long before you see gains. “If consistent in training to increase VO2 max, people should start to notice a difference in approximately six weeks,” says Gatlin.
Research backs up the keys that unlock better VO2 max: Runners who did 200-meter interval workouts for only 10 weeks improved their aerobic capacity and VO2 max significantly more than runners who stuck to moderately-paced workouts, according to a 2018 study published in the Journal of Strength and Conditioning Research. Similarly, people who did HIIT sessions with intervals as short as 30 seconds for four weeks or less showed VO2 max improvements in a 2019 meta-analysis of studies published in the Running Shoes - Gear; participants who did intervals closer to two minutes for four to 12 weeks showed even greater gains.
5 Workouts to Challenge Your VO2 Max
CA Notice at Collection heart-rate zone during those intervals. “In general, VO2 max work should be completed at about 90 to 100 percent of your Before each of these sessions,” says Benson. That’s about the same as a 5K pace, and each of the five workouts below—recommended by Benson and Gatlin—include intervals at that approximate intensity. Feel free to dial it back a bit, Benson says, if you’re new to this type of training.
Before each of these sessions, warm up by jogging for eight to 15 minutes, then do some dynamic stretches or range of motion drills, like high knees and leg swings, followed by a few reps of 20-second strides to prep your body to pick up the pace.
The tough interval sections of the workouts can range from about 10 minutes for novices to 25 minutes for advanced runners; pick your reps below to dial into the right level for your fitness. It’s always smart to start on the lower end, see how it feels, and work your way up to more reps.
Benson recommends doing a VO2 max workout twice a month for newbies, up to once a week for more experienced runners. And for the biggest benefit, be careful not to schedule them the day after a long run or other challenging session. “These types of workout sessions should be done during the week and sandwiched between two very easy days of running, cross training, or rest days,” says Benson.
