The body’s demand for oxygen increases during exercise, necessitating a boost in breathing volume and requiring various muscles around the lungs to contract in coordination. As the intensity of the exercise rises, these respiratory muscles have to contract with increased force and rapidity to keep up with the rise in the body’s metabolism. This vital role of the respiratory muscles has generated much interest in the relationship between respiratory muscle fitness and ‘whole-body’ exercise capacity.
Studying The Process
In a study published by G. Markov, et al, entitled, Respiratory Muscle Training [RMT] Increases Cycle Endurance without Affecting Cardiovascular Responses to Exercise, it was “concluded that the increased cycling endurance that is observed after RMT is not due to cardiovascular adaptations, and that the results provide evidence for the role of the respiratory system as an exercise-limiting factor.” What does this mean? It means that weak respiratory muscles can hold back your performance.
Studies have also found impressive improvements in respiratory muscle strength and endurance even in well-trained athletes (Sonetti et al. 2001). This finding is important because it shows the potential for improved respiratory muscle function in individuals who engage in strenuous physical training regularly.
Independent studies have shown that the muscles of the respiratory system are the single and biggest limiting factor in cycling training and race performances.
How To Train These Muscles
Training specific to the respiratory muscles is accomplished independent of whole-body exercise and is usually undertaken in one of two ways. In isocapnic hyperpnoea, the person breathes at an increased level of ventilation for a long time. This training method, similar to the breathing demands of endurance exercise, helps to develop the stamina of respiratory muscles. Threshold loading builds respiratory muscles strength by breathing for a shorter time against a resistance, similar to traditional weight training. By adjusting the settings, PowerLung can accomplish both methods.
Respiratory Muscle Training (RMT) increases vital capacity, increases oxygen intake, reduces respiratory rate, and lowers the heart rate. Increased oxygen intake with less breathing effort improves energy production through faster glucose and lactic acid breakdown, releasing more energy for your cycle training and racing fitness.
You’ll Notice The Difference
Remember the study from earlier, while they noticed significant differences in endurance by just training the respiratory muscles in one direction (inhale or exhale) PowerLung trains in both directions providing a full respiratory system workout.
Increasing your oxygen supply through RMT results in more energy production for explosive breaking and sprinting from the peleton or when racing in the velo. Faster and easier pace-line speeds on the road and in velodrome team races can be attained. On the tour, climbers and respected mountain men have come to appreciate the endurance value of RMT on the climbs, in attempted blasts at the bottom of the wall and from the punishment of consecutive days of racing in the mountains.
Bonking is usually caused when weak or untrained respiratory muscles become fatigued, regardless of what type of bike you race. The warning signs of respiratory fatigue are:
- Shallow breathing
- Not being able to take a deep breath anymore
- Leg muscles burning and feeling on fire, and
- Finally your bike speed dies
Use PowerLung twice a day for 10 minutes to strengthen the muscles that support your breathing. It’s that easy!
