Impact of Inspiratory Muscle Training on Lung Function and Aerobic Fitness in Recreational Basketball Athletes
Description
This title refers to research exploring how targeted exercises for the breathing muscles-known as inspiratory muscle training (IMT)-can affect the lung function and aerobic fitness of individuals who play basketball recreationally. Basketball is a sport that requires both strong respiratory muscles and high endurance due to its demanding nature and frequent bursts of intense physical activity. While most athletic training programs focus on building strength, agility, and basketball skills, there is growing interest in understanding whether specifically strengthening the muscles involved in inhalation can further enhance a player’s lung capacity and ability to sustain prolonged physical effort. Studies in this area assess whether IMT can lead to measurable improvements in parameters such as forced vital capacity, maximum voluntary ventilation, and oxygen uptake, ultimately aiming to determine if these physiological gains translate into better performance and reduced fatigue during basketball games

The study recruited recreational basketball players who met inclusion criteria (e.g., no respiratory conditions, consistent training habits) and randomly assigned them to Group A (experimental) and Group B (control) using allocation concealment methods. Group A underwent inspiratory muscle training (IMT) using a POWERbreathe device for 4 weeks, starting at 50% maximal inspiratory pressure (MIP) with weekly progression based on tolerance. Sessions involved 30 breaths twice daily, mimicking protocols shown to induce diaphragm hypertrophy. Group B performed sham training at 15% MIP, a subtherapeutic intensity serving as a placebo. Pulmonary function was assessed via spirometry, measuring forced vital capacity (FVC), forced expiratory volume in 1 second (FEV₁), and FEV₁/FVC ratio. Aerobic capacity was evaluated using the Queen’s College Step Test, where participants stepped at 24 steps/minute (males) or 22 steps/minute (females) for 3 minutes, with post-exercise heart rate used to estimate VO₂ max.
