Aerobic and anaerobic training: what are the differences?

When it comes to endurance sports like running, cycling, and swimming, understanding the differences between aerobic and anaerobic training is crucial for optimizing performance and achieving fitness goals. Both types of training play distinct and complementary roles in improving overall fitness. Let’s explore the main characteristics of each type of training and how they apply to endurance sports.

Aerobic training

Definition: The term “aerobic” comes from the Greek words “aero,” meaning “air,” and “bios,” meaning “life.” Together, they refer to biological processes that require oxygen to produce energy. In the context of training, aerobic activity involves the continuous use of oxygen to generate energy, allowing for long-duration, low-intensity activities.

Examples of activities:
  • Moderate pace running: Running at a pace that can be maintained for more than 30 minutes without excessive fatigue.
  • Long-distance cycling: Cycling for hours at a steady speed.
  • Endurance swimming: Swimming long distances at a consistent pace.
Benefits:
  • Improves cardiovascular endurance: Strengthens the heart and lungs, enhancing the body’s ability to transport and utilize oxygen.
  • Increases endurance capacity: Allows for sustained physical activity over long periods, improving muscle efficiency.
  • Burns calories and fat: Aids in weight loss and improves body composition.
  • Enhances recovery: Facilitates quicker recovery after intense exercise by improving the body’s ability to handle physiological stress.

Anaerobic training

Definition: Anaerobic training includes high-intensity exercises performed for short periods. It uses muscle glycogen to produce energy without the use of oxygen.

Examples of activities:
  • Sprint running
  • High-intensity hill climbing in cycling
  • Fast swimming over short distances
  • Weightlifting
Benefits:
  • Increases muscle strength: Enhances muscle power, improving the ability to perform intense efforts.
  • Improves power and speed: Fosters explosive performance.
  • Boosts metabolism: Increases calorie consumption even at rest due to the increase in muscle mass.
  • Tones muscles: Contributes to better muscle definition and a more toned appearance.

Key differences

Here is a summary table of the main differences between aerobic and anaerobic training:

Characteristic Aerobic Training Anaerobic Training
Intensity and duration Low intensity, long duration High intensity, short duration
Energy system Uses oxygen to produce energy Uses muscle glycogen, does not require oxygen
Fitness goals Improves cardiovascular endurance and burns fat Increases strength, power, and muscle mass
Examples in sports Steady pace running, long-distance cycling, endurance swimming Sprint running, hill climbing in cycling, fast swimming, weightlifting
Recovery time Requires less recovery time Requires more recovery time

Threshold points

In the context of physical training, threshold points are essential for understanding how the body transitions from using one energy system to another during exercise. The main threshold points are:

  1. Aerobic threshold (AeT): This point marks the maximum intensity at which the body can sustain exercise primarily using aerobic metabolism. It is typically reached during low-intensity, long-duration activities like light running or long-distance cycling.
  2. Anaerobic threshold (AnT): This point represents the intensity at which the body starts to rely more on anaerobic metabolism for energy production. Beyond this threshold, lactate accumulation in the blood increases, leading to greater fatigue. It is common in high-intensity exercises such as sprints or steep hill climbs in cycling.
  3. Functional threshold power (FTP): Particularly relevant in cycling, FTP represents the maximum average power a cyclist can maintain for one hour without excessive lactate accumulation. This parameter is crucial for assessing the ability to sustain high-intensity efforts.
Methods for calculating threshold:
  • Lactate testing: Measures blood lactate levels during incremental exercise. Rapid increases in lactate levels indicate the anaerobic threshold.
  • Heart rate testing: Uses heart rate to determine thresholds. The aerobic threshold is often around 70% of maximum heart rate, while the anaerobic threshold is around 85%.
  • Spiroergometry: Measures the ratio of oxygen intake to carbon dioxide output during incremental exercise. Significant changes in this ratio indicate the shift between aerobic and anaerobic metabolism.
  • FTP test: For cycling, an FTP test can be performed by measuring the average power output over 20 minutes, then calculating 95% of that value to determine FTP.

Importance in training: Knowing your thresholds is essential for customizing training, improving energy efficiency, and optimizing performance. Training near the aerobic threshold can enhance overall endurance, while training near the anaerobic threshold can increase the ability to sustain intense efforts and improve lactate tolerance. FTP helps cyclists plan effective training sessions and monitor progress over time.

Combining both

For endurance athletes, it is essential to integrate both aerobic and anaerobic training into their programs. For example, runners can benefit from long, moderate-paced runs to improve endurance, combined with sprint sessions to increase speed and power. Cyclists can alternate long road rides with intense hill climbs, while swimmers can combine endurance sessions with high-intensity sprints.

Combining both types of training can also offer excellent results for weight loss. Aerobic training is generally considered more effective for weight reduction as it allows for burning a high number of calories during the exercise itself due to the long duration of the sessions. However, anaerobic training, such as HIIT (High-Intensity Interval Training), can be equally effective because it increases basal metabolism, allowing for calorie burn even after the workout thanks to the afterburn effect.

In conclusion, a balanced training program that includes both aerobic and anaerobic components will help endurance athletes improve their performance, increase endurance, optimize physical condition, and lose weight. Understanding and leveraging the differences between these two types of training is key to reaching the highest level in your sport.
