Let's immediately dive into this Q&A session with Sascha Rado, founder of Activate Personal Training Studio in Barcelona and renowned health & performance coach.
So I am a recreational runner and heard about M.A.F. recently. What does M.A.F. stand for and how can it improve my performance?
In the context of the Maffetone Method, M.A.F. stands for "Maximum Aerobic Function." The Maffetone Method is an approach to endurance training developed by Dr. Philip Maffetone, a renowned coach and researcher. It focuses on optimizing aerobic function and improving endurance performance by training at an intensity level that maximizes fat burning and minimizes stress on the body. The Maximum Aerobic Function (MAF) is a key concept in this method. It refers to the maximum heart rate at which an individual can exercise while still primarily utilizing fat as a fuel source. By training at or below this heart rate, athletes aim to develop their aerobic base, improve fat metabolism, and enhance their endurance capacity. To determine an individual's MAF heart rate, Dr. Maffetone typically suggests subtracting their age from 180 and then making adjustments based on their fitness level, health status, and training history. The MAF heart rate serves as a guideline for training intensity, helping athletes avoid excessive stress and improve their aerobic fitness over time.
In what way does this relate to or resemble the concepts presented in Iñigo San Millan's zone 2 training?
Iñigo San Millan's Zone 2 training and the Maffetone Method share some similarities in terms of training intensity and aerobic development. Both approaches emphasize the importance of training at lower intensities to enhance aerobic capacity and fat metabolism. However, there are some differences in how they determine training zones. In the Maffetone Method, the Maximum Aerobic Function (MAF) heart rate is calculated using a formula that takes into account factors such as age, fitness level, health status, and training history. The MAF heart rate serves as a training threshold, and athletes are advised to stay below this heart rate during their workouts. On the other hand, Iñigo San Millan's Zone 2 training typically involves using lactate threshold or functional threshold power (FTP) to establish training zones. Zone 2 refers to an intensity level that is below the lactate threshold, where the body can effectively clear lactate and maintain a balance between aerobic and anaerobic energy systems. The specific heart rate associated with Zone 2 may vary depending on an individual's lactate threshold or FTP. While the overall goal of both approaches is to improve aerobic capacity, the methods for determining training intensity and heart rate zones differ. The Maffetone Method focuses on an individualized calculation of the MAF heart rate, while Iñigo San Millan's Zone 2 training typically involves establishing training zones based on lactate threshold or FTP.
Could you perhaps provide a bit more in-depth comparisons?
When comparing the Maffetone Method and Iñigo San Millan's Zone 2 training in terms of training intensity and aerobic development I would mainly look at the following variables:
Training Intensity:
- Maffetone Method: The Maffetone Method determines training intensity using the Maximum Aerobic Function (MAF) heart rate formula. It takes into account factors such as age, fitness level, health status, and training history. The MAF heart rate serves as a training threshold, and athletes are advised to keep their heart rate below this threshold during their workouts.
- Zone 2 Training: Iñigo San Millan's Zone 2 training establishes training zones based on lactate threshold or functional threshold power (FTP). Zone 2 refers to an intensity level below the lactate threshold, where the body can efficiently clear lactate and maintain a balance between aerobic and anaerobic energy systems. The specific heart rate associated with Zone 2 varies depending on an individual's lactate threshold or FTP.
Determining Training Zones:
- Maffetone Method: The Maffetone Method calculates the MAF heart rate by subtracting the individual's age from 180 and making adjustments based on various factors. This approach aims to find the maximum heart rate at which an individual can exercise while primarily utilizing fat as a fuel source. Training intensity is then kept below this heart rate to optimize aerobic function and fat metabolism.
- Zone 2 Training: Zone 2 training determines training zones based on an individual's lactate threshold or FTP. These thresholds are typically determined through physiological testing or performance assessments. The heart rate associated with Zone 2 is generally set at a percentage of the lactate threshold or FTP, often around 70-80% of the threshold heart rate.
Focus on Aerobic Development:
- Maffetone Method: The Maffetone Method places a strong emphasis on developing the aerobic system. By training at or below the MAF heart rate, the method aims to improve aerobic fitness, enhance fat metabolism, and build a solid aerobic base. This approach emphasizes the importance of efficient fat utilization for energy during endurance activities.
- Zone 2 Training: Zone 2 training also prioritizes the development of aerobic capacity. By training below the lactate threshold, athletes can stimulate adaptations that improve the body's ability to use oxygen, enhance mitochondrial function, and increase endurance performance. This approach aims to strike a balance between aerobic and anaerobic energy systems, optimizing endurance capacity.
While both approaches share a focus on aerobic development and training at lower intensities, the Maffetone Method's MAF heart rate calculation is based on individual factors, while Zone 2 training typically relies on lactate threshold or FTP testing to establish training zones. Athletes can choose the approach that aligns best with their preferences and available resources for determining training intensity.
Is Zone 2 Training therefore a more accurate method given the fact athletes measure blood lactate levels?
Zone 2 training, which incorporates lactate threshold testing, can provide a more accurate and individualized approach to determining training intensity compared to the Maffetone Method's MAF heart rate calculation. Here's why:
Lactate threshold testing involves measuring blood lactate levels at increasing exercise intensities to identify the point at which lactate begins to accumulate in the bloodstream. This threshold indicates the transition from predominantly aerobic to anaerobic energy production. By determining an athlete's lactate threshold, specific training zones can be established, including Zone 2. This method allows for a more precise and individualized assessment of training intensity based on physiological markers. Furthermore, lactate threshold testing provides information about an individual's unique physiological response to exercise. It helps identify the intensity at which an athlete can sustain an effort for an extended period. By establishing personalized training zones based on lactate threshold, athletes can target specific physiological adaptations, optimize training stimulus, and enhance their endurance performance. Lastaly I look at adaptability to fitness level and progression. Lactate threshold testing allows for the adjustment of training zones as an athlete's fitness level improves. As the lactate threshold increases with training, the corresponding heart rate or power associated with Zone 2 can be adjusted accordingly. This adaptability ensures that the training intensity remains appropriate and effective as the athlete's aerobic capacity improves over time. It's important to note that lactate threshold testing requires specialized equipment and expertise to conduct accurately. While it offers a precise approach, it may not be readily accessible to all athletes. In such cases, the Maffetone Method's MAF heart rate calculation can provide a useful guideline for training at a lower intensity, emphasizing aerobic development and fat metabolism.

Ultimately, the choice between the Maffetone Method and Zone 2 training depends on the athlete's preference, available resources, and training goals. Both approaches can be effective in enhancing aerobic capacity and improving endurance performance when applied correctly.
Is there a method favored by runners vs. cyclists vs. triathletes for example? Or is there a difference between the methods professional vs. recreational athletes use?
The choice of training method, such as the Maffetone Method or Zone 2 training, can vary among different sports disciplines, as well as between professional and recreational athletes. While there is no definitive divide, here's a general overview of how I think certain training methods may be favored by different groups:
Runners: Many runners, both professional and recreational, utilize a variety of training methods depending on their goals, preferences, and training philosophies. Some may incorporate the Maffetone Method or Zone 2 training to focus on aerobic development and endurance capacity. Others may employ interval training, tempo runs, or speed workouts to improve speed, anaerobic capacity, and race-specific performance.
Cyclists: Cyclists, particularly those engaged in endurance disciplines like road cycling or long-distance cycling events, often prioritize aerobic development and efficiency. Zone 2 training, based on lactate threshold or FTP, is commonly used to enhance endurance capacity and sustainable power output. Additionally, structured interval training and hill repeats are frequently employed to improve power, strength, and speed on the bike.
Triathletes: Triathletes participate in multi-sport events that combine swimming, cycling, and running. Training approaches among triathletes can vary widely depending on individual strengths, weaknesses, and race distances. Aerobic development and endurance training methods like the Maffetone Method or Zone 2 training are commonly utilized. Triathletes may also incorporate sport-specific training sessions, brick workouts (consecutive swim-bike or bike-run sessions), and transitions to prepare for the demands of their races.
Professional vs. Recreational Athletes: The training methods used by professional athletes often involve more individualized and scientific approaches. They may have access to specialized coaches, sports scientists, and physiological testing to fine-tune their training zones and intensities. Professionals often incorporate a wide range of training methods tailored to their specific event and performance goals. Recreational athletes, on the other hand, may adopt more simplified or accessible training approaches, including the Maffetone Method or Zone 2 training, to improve their fitness and enjoy their chosen sport.
The preferences and practices of athletes can vary significantly, and there are no strict boundaries. Athletes often experiment with different training methods and adapt their approach based on personal experience, performance feedback, and the guidance of coaches or experts in their respective sports. The most effective training method ultimately depends on individual factors, including goals, fitness level, available resources, and personal preference.
Apart from the Maffetone and Zone 2 Training methods, what other training methods can you name?
There are several other effective training methods utilized by athletes to enhance their performance and fitness. Notable training methods include: High-Intensity Interval Training (HIIT): HIIT involves alternating periods of high-intensity exercise with short recovery periods. It is a time-efficient training method that can improve aerobic and anaerobic fitness, increase metabolic rate, and enhance cardiovascular performance. HIIT workouts can be tailored to various sports and fitness levels. Fartlek Training: Fartlek, a Swedish term meaning "speed play," involves incorporating intervals of varying intensity into a continuous training session. It combines periods of faster-paced running or cycling with slower recovery segments. Fartlek training is flexible, allowing athletes to adapt their intensity and duration based on terrain, personal preference, and training objectives. Long Slow Distance (LSD) Training: LSD training involves performing prolonged workouts at a low to moderate intensity. It aims to improve aerobic endurance, develop slow-twitch muscle fibers, enhance fat utilization, and promote mental resilience during prolonged efforts. LSD training is commonly used in endurance sports such as distance running, cycling, and swimming. Tempo Training: Tempo training involves sustained efforts at a steady pace slightly below lactate threshold or comfortably hard intensity. It helps improve lactate clearance, raise lactate threshold, and enhance endurance performance. Tempo runs, rides, or swims are typically sustained for 20-60 minutes at a challenging but sustainable pace. Interval Training: Interval training involves alternating periods of high-intensity effort with periods of rest or lower intensity. It can be structured in various ways, such as short, intense efforts followed by brief recovery periods or longer intervals at near-maximal effort. Interval training improves anaerobic capacity, speed, power, and overall fitness. Strength Training: Strength training involves exercises that target muscular strength, power, and endurance. It helps improve athletic performance, injury prevention, and overall functional strength. Strength training can be incorporated using bodyweight exercises, resistance training machines, free weights, or functional training methods. Lastly Cross-Training: Cross-training involves participating in activities other than the primary sport to improve overall fitness, prevent overuse injuries, and provide variety in training. For example, a runner may include swimming or cycling in their routine to complement their running workouts. These are just a few examples of effective training methods. Different sports, athletes, and training goals may require unique training approaches and combinations of methods. It's essential to tailor training programs to individual needs, seek guidance from experts or coaches, and gradually progress to avoid overtraining and maximize performance gains.
How can these methods benefit non-athletes, such as busy professionals for example?
These training methods can benefit inactive people in various ways, as many of these methods, such as HIIT, Fartlek training, and interval training, are time-efficient options for individuals with busy schedules. They allow for effective workouts in shorter durations, making it easier to fit exercise into a hectic lifestyle. These training methods can also enhance cardiovascular fitness, increase metabolic rate, and improve overall health markers, such as blood pressure, cholesterol levels, and insulin sensitivity. Regular exercise can reduce the risk of chronic diseases and promote overall well-being. Exercise has significant stress-relieving and mood-boosting effects. Engaging in any of these training methods can provide a break from work-related stress, improve focus and productivity, and contribute to better mental health and resilience. Incorporating these training methods, particularly those that involve higher intensity intervals or strength training, can support weight management goals. They help increase calorie burn, improve metabolism, build lean muscle mass, and enhance body composition. Strength training, including weightlifting and functional training, can benefit sedentary people by promoting better movement mechanics, increasing bone density, and reducing the risk of injuries related to daily activities or sedentary lifestyles. It helps build overall strength, stability, and functional fitness. All of the aforementioned training methods offer variety and versatility in workouts, making exercise more engaging and enjoyable. Trying different methods can keep individuals motivated and prevent boredom or plateaus in their fitness routines. Engaging in regular exercise, regardless of the training method, contributes to improved energy levels, better sleep patterns, enhanced cognitive function, and increased self-confidence. These benefits positively impact overall well-being and quality of life. Of course, it is very important to consider individual fitness levels, goals, and any specific health concerns when incorporating these training methods. Consulting with a fitness professional or seeking guidance from experts can ensure proper form, progression, and safety in training programs tailored to individual needs.
What about benefits to cardiovascular health or for example metabolic health i.e. mitochondrial biogenesis?
The training methods I mentioned before offer significant benefits to cardiovascular health and can contribute to mitochondrial biogenesis, the process of increasing the number and efficiency of mitochondria in cells. There are several ways as to how they can impact these aspects:
A) Cardiovascular Health: Many of these training methods, such as HIIT, Fartlek training, and tempo training, place a strong emphasis on improving cardiovascular fitness. They challenge the cardiovascular system by increasing heart rate, improving oxygen uptake, and enhancing the efficiency of the heart and lungs. Regular participation in these methods can lead to improved cardiovascular function, increased stroke volume, enhanced cardiac output, and better overall cardiovascular health.
B) Mitochondrial Biogenesis: Mitochondria are the powerhouses of cells responsible for energy production. Engaging in endurance-based training methods, such as Zone 2 training, long slow distance (LSD) training, and tempo training, can stimulate mitochondrial biogenesis. These methods specifically target the aerobic energy system, requiring the utilization of oxygen and promoting the development of more efficient mitochondria. With regular training, the capacity for energy production in the mitochondria increases, leading to improved endurance performance and overall cellular function.
C) Oxidative Capacity: Endurance-focused training methods that emphasize aerobic development, such as Zone 2 training and LSD training, enhance oxidative capacity. These methods promote the utilization of fatty acids as a fuel source, leading to improved fat metabolism and a decreased reliance on carbohydrates during exercise. The increased oxidative capacity allows for prolonged endurance efforts, delays the onset of fatigue, and supports overall cardiovascular and metabolic health.
D) VO2 Max Improvement: VO2 max, the maximum amount of oxygen an individual can utilize during intense exercise, is an important indicator of cardiovascular fitness. Training methods like HIIT and interval training, which involve brief, intense efforts followed by recovery, have been shown to significantly increase VO2 max. These methods improve the body's ability to transport and utilize oxygen, enhancing aerobic capacity and performance potential.
Overall, these training methods can have substantial positive impacts on cardiovascular health, mitochondrial biogenesis, oxidative capacity, and VO2 max. However, it's important to note that individual responses may vary, and the duration, frequency, and intensity of training play significant roles in achieving these benefits. A progressive approach, appropriate for an individual's fitness level and goals, along with consistency and proper recovery, is crucial for maximizing cardiovascular adaptations and mitochondrial function.
What is the difference between mitochondrial biogenesis and mitochondrial function? How does both concepts relate to the aforementioned training methods?
Mitochondrial biogenesis and mitochondrial function are related concepts but represent different aspects of mitochondrial health and performance. Let me quickly give you a breakdown of the differences between the two and their relationship to the training methods mentioned:
Mitochondrial biogenesis refers to the process by which new mitochondria are formed within cells. It involves an increase in the number of mitochondria, as well as the replication and division of existing mitochondria. This process is influenced by various factors, including exercise, metabolic demands, and cellular signaling pathways. Training methods that emphasize endurance and aerobic capacity, such as Zone 2 training, long slow distance (LSD) training, and tempo training, have been shown to stimulate mitochondrial biogenesis. By consistently challenging the aerobic energy system, these training methods provide a stimulus for the body to adapt and increase mitochondrial content within cells. Mitochondrial function refers to the efficiency and effectiveness of the existing mitochondria in generating ATP (adenosine triphosphate), the energy currency of cells. It encompasses processes such as oxidative phosphorylation, the electron transport chain, and the production of ATP. Mitochondrial function is influenced by factors such as the density of mitochondria, the integrity of mitochondrial membranes, and the activity of enzymes involved in energy production. Training methods that target aerobic capacity, such as Zone 2 training and tempo training, enhance mitochondrial function by improving the efficiency of ATP production and utilization within mitochondria. As to the relationship to the training methods we spoke about earlier: training methods that stimulate mitochondrial biogenesis, such as Zone 2 training, long slow distance (LSD) training, and tempo training, promote the formation of new mitochondria within cells. This increase in mitochondrial content enhances the overall capacity for energy production and supports improved endurance performance. Training methods that emphasize aerobic capacity and mitochondrial function, such as Fartlek, HIT, HIST and tempo training, enhance the efficiency of existing mitochondria. These methods improve oxidative phosphorylation and ATP production, leading to better energy utilization, increased endurance capacity, and improved overall mitochondrial function. Both mitochondrial biogenesis and mitochondrial function are interrelated and mutually dependent. The formation of new mitochondria (biogenesis) contributes to increased mitochondrial function, and improved mitochondrial function supports the optimal performance of existing mitochondria. Together, these processes play a crucial role in energy production, aerobic capacity, and endurance performance.
How do these then relate to longevity and disease prevention, I am thinking cancer, diabetes, heart disease, etc?
Mitochondrial health, including mitochondrial biogenesis and function, plays a significant role in longevity and disease prevention. Mitochondrial dysfunction has been implicated in the aging process and age-related diseases. As we age, mitochondrial function tends to decline, leading to decreased energy production and increased production of reactive oxygen species (ROS), which can cause cellular damage. By promoting mitochondrial biogenesis and optimizing mitochondrial function through exercise and training methods, it is believed that the aging process can be attenuated or slowed down. Regular physical activity, including endurance training methods, has been associated with improved mitochondrial health and longevity. Mitochondrial dysfunction is also closely linked to cancer development and progression. Dysfunctional mitochondria can affect energy metabolism, promote genomic instability, and impair cell death mechanisms. Exercise and training methods that promote mitochondrial biogenesis and optimize mitochondrial function may have beneficial effects in cancer prevention and adjunctive cancer treatment. Regular exercise has been associated with a reduced risk of certain cancers and improved outcomes in cancer patients. Mitochondrial dysfunction is furthermore implicated in the development of insulin resistance and type 2 diabetes. Impaired mitochondrial function can lead to reduced glucose utilization and increased lipid accumulation, contributing to metabolic abnormalities. Training methods that improve mitochondrial function, such as aerobic exercise and high-intensity interval training (HIIT), have been shown to enhance insulin sensitivity and glucose metabolism. Regular exercise can help prevent or manage diabetes by improving mitochondrial health and metabolic function. Lastly, mitochondrial dysfunction is implicated in various cardiovascular diseases, including heart failure, ischemic heart disease, and cardiomyopathies. Impaired mitochondrial function can lead to decreased energy production, oxidative stress, and cellular damage in the heart muscle. Exercise and training methods that promote mitochondrial biogenesis and optimize mitochondrial function can enhance cardiac energy metabolism, improve heart function, and reduce the risk of cardiovascular diseases. Regular aerobic exercise, such as Zone 2 training and tempo training, has been associated with a lower incidence of heart disease and improved cardiovascular health. While exercise and training methods can have positive effects on mitochondrial health, they should be considered as part of a comprehensive approach to overall health and disease prevention. Factors such as a balanced diet, stress management, and regular medical check-ups are also crucial for maintaining longevity and reducing the risk of various diseases.
