Endurance Training and Strength Training: Understanding Their Effects and Finding the Right Balance for Better Performance
Well-planned, long-term endurance training can have a remarkable impact on your body. This article explores the positive effects of endurance training on the body while showing you how to find the ideal balance between strength and endurance training. Before we take a closer look at this topic, let's first define what endurance actually means.
What Is Endurance?
The Positive Effects of Endurance Training on the Body
Endurance training has a positive effect on several body systems:
- Cardiovascular System: Endurance athletes often develop a stronger and more efficient heart, allowing it to pump more blood with each beat while maintaining a lower heart rate. Both resting and exercise heart rates decrease significantly due to improved oxygen delivery and cardiovascular efficiency.
- Respiratory System: Improved breathing efficiency and increased ventilation capacity are among the many benefits of effective endurance training.
- Muscle Metabolism: Mitochondria—the structures responsible for producing energy in the form of ATP—increase both in number and size. At the same time, blood supply and nutrient delivery to the muscles improve through increased capillarisation.
- Immune System: Regular endurance training strengthens the immune system and enhances the body's natural defence mechanisms.
- Mental Health: Endurance exercise contributes to improved well-being, reduced stress levels, and greater body awareness.
The Art of Combining Strength and Endurance Training
How Endurance Training Affects Strength Performance
Research shows that endurance training can influence the body's adaptations to strength training. The frequency, volume, and intensity of endurance workouts have the greatest impact on explosive strength, while hypertrophy and maximal strength are generally affected to a lesser extent.
To minimise interference with strength development, it is generally recommended to perform endurance training no more than three to four times per week using low to moderate training volumes and keeping the intensity below approximately 80% of your individual VO₂max.
How Strength Training Improves Endurance Performance
Studies have shown that strength training can improve endurance performance in both short- and long-distance running. The best results are typically achieved by focusing on explosive strength and maximal strength training over a period of at least eight weeks.
Summary: Finding the Right Balance
For most athletes, combining strength and endurance training is essential. When programmed correctly, concurrent training does not negatively affect strength adaptations and can even improve endurance performance. The key is to manage training intensity, frequency, and recovery appropriately.
