The 5 Essentials for Sustaining a Low Heart Rate

Before diving into these techniques, it’s important to note that heart rate training may not be suitable for everyone. If you're new to running or do it as a casual hobby, focus on simply getting out there without stressing about physiological metrics. These insights are more relevant for those serious about enhancing their endurance or speed, particularly if preparing for a race.

It's also crucial to understand that the benefits from these strategies take time to develop—often months or even years. While the elements we discuss are vital for boosting cardiovascular fitness, the fundamental principle remains: volume multiplied by consistency. Regardless of technical details, consistent effort is key, so approach your training with patience.

Now, let’s explore how to keep your heart rate low and your effort feeling manageable!

1. Regulate Your Body Temperature

Most runners perform best when temperatures range from 39 to 50 degrees Fahrenheit. These conditions help maintain a neutral internal temperature, reducing excessive sweating and delaying cardiovascular drift. For instance, a runner may see their heart rate rise by 10 to 20 beats per minute when running in 90°F (32°C) versus 75°F (23°C).

While ideal running conditions may not always be possible, consider adjusting your pace or training volume based on the weather. If you live in extreme climates, running on a treadmill during hot months or using cooling agents can help manage your internal temperature effectively.

While acclimatizing to warmer conditions can be beneficial, it’s a gradual process often requiring professional guidance. Recreational runners should strive to create the best possible environment for their training sessions.

2. Stay Hydrated and Properly Fueled

When you sweat without replenishing fluids, your blood volume decreases, causing your heart rate to rise to accommodate your body’s needs. This is less of a concern during shorter runs, but it’s essential to hydrate during efforts exceeding 8 to 10 miles.

As your runs grow longer and are performed in hotter conditions, incorporating electrolytes and carbohydrates becomes crucial. This will help prevent early fatigue and affect the timing of cardiovascular drift.

Ensuring you remain hydrated and fueled during your runs will prevent your heart from having to work harder than necessary.

3. Emphasize Strength Training and Hill Work

While it may sound simplistic, fatigued muscles become less efficient and consume more energy, which can elevate your heart rate. To counteract this, engage in strength training outside of running—exercises like squats, lunges, and calf raises are beneficial.

Additionally, incorporating hills into your training—such as rolling hills during long runs or short hill sprints—will help develop stronger muscles that utilize fuel more efficiently, allowing you to sustain longer and faster efforts.

4. Implement Drills to Boost Running Economy

Running drills, including A skips, high knees, and straight-leg bounds, are more than just warm-up exercises. They enhance cadence, improve form, and optimize neuromuscular function. No matter your fitness level, everyone can benefit from these drills. They foster faster neural connections and stronger tissues, making them an excellent way to reduce injury risk.

From the perspective of heart rate training, a more efficient running economy means you will require less fuel and oxygen to maintain a specific pace. Practicing drills and strides—especially when fatigued—will lessen the load on your cardiovascular system, allowing for a more sustainable running experience.

5. Engage in Threshold Training

Threshold training involves running at or just below your anaerobic threshold, typically within heart rate zones 3/4 and 4.0mmol/L of lactate. In simpler terms, this is challenging yet manageable work; you should be able to utter a few words but not hold a full conversation.

While threshold training shouldn’t be performed for every run, aim to include it 1-2 times a week. This will enhance your body's ability to clear metabolic waste, helping to keep your heart rate lower for longer.
