Abstract Inspiratory muscle training (IMT) is widely implemented among athletes and patients, but its effects in sedentary adolescent students remain unclear. This randomized controlled trial investigated the effects of 12-week IMT on respiratory function and aerobic capacity in sedentary adolescent boys. For this aim, 41 sedentary male-adolescents (16–18 years) were assigned randomly into IMT (n = 20) or Sham (n = 21) group.

1 Introduction Puberty is a critical period for bone mineral accumulation (1). At this time, bone mass accumulates rapidly (about 50% of peak bone mass is achieved), and about 90% of peak bone mass can be achieved by the end of adolescence (2). Adolescence is a key window to increase peak bone mass, and the accumulation of bone mass during this period helps to reduce the risk and severity of osteoporosis in later life (3).
