In order to win, you need energy and power of will. While the latter is all mental, the energy part can be worked on. However, that's only possible if you breathe correctly. Improving your respiratory strength can let you increase the amount of oxygen inhaled in a given period, that will result in a decrease in energy consumption. The process of ventilation between air and blood occurs through neurological control of the respiratory muscles. Muscles related to respiration may be divided into inspiratory and expiratory muscles. Major muscles engaging in inspiration include the diaphragm and external intercostal muscle, and minor muscles engaging in inspiration encompass the sternocleidomastoid muscle, scalene muscle, trapezius muscle, pectoralis major muscle, pectoralis minor muscle, and serratus anterior muscle. These muscles act during forced expiration. Expiratory muscles that do not act in normal respiration but do act in strong respiration include the rectus abdominis muscle, musculus transversus abdominis, external and internal oblique abdominal muscle, and internal intercostal muscle. Weakening of the respiratory system muscles is a risk factor for cardiovascular disease, and these muscles play a role in reducing the pressure of the lower abdomen during respiration.


On the other hand, there is a respiratory muscle strength training (RMST), that focuses on increasing the force-generating capacity of the inspiratory and expiratory muscles. The choice of respiratory muscles that are targeted using RMST depends on the outcome desired. For example, if an individual has reduced inspiratory muscle strength due to a neurogenic injury and is unable to ventilate the lungs, then inspiratory muscle strength training may be the chosen rehabilitation target. Research has shown, that respiratory muscle training strengthens the respiratory muscles and improves your ability to perform different activities. Respiratory Muscle Training can be defined as a technique that aims to improve function of the respiratory muscles through specific exercises. It consists of a series of exercises, breathing and other, to increase strength and endurance of the respiratory muscles and therefore improve respiration. 


By increasing the strength and stamina of your respiratory system, your breathing becomes more efficient, requiring less energy, which leaves more energy for the motor muscles and whatever task or activity you’re involved in. Therefore, you can take slower, deeper breaths, getting more oxygen out of each breath; you don’t have to work as hard to get it, because you don’t have to breathe as many times to get the same amount of oxygen. Improved way of breathing leads to efficient gas exchange in the lungs and use of breathing muscles. It also increases the blood’s oxygen-carrying capacity and cleans the blood making it more fluid. These aspects have a great effect on the oxygen transportation from to lungs to the muscles. That result in better oxygenation thus increased oxygen intake and ability to perform better and for a longer time with a bigger effort. 

Respiratory muscle training (RTM) can improve sports performance and clearly increases respiratory muscle strength and endurance. According to the specificity of training, benefits might be greatest when the muscle contraction parameters such as range of motion and speed of contraction match the demands of the sports. Moreover, an aggressive progression of RMT intensity to ensure a training overload is essential for optimal benefit. RMT is normally aimed at people who suffer from asthma, bronchitis, emphysema, and COPD. However, many people adopt RMT as part of their sports training as this training is designed to strengthen the muscles used for breathing. Studies have shown that regular RMT can increase a person’s endurance during cardiovascular exercise or sports activities such as running and cycling.
