Effect of Exercises on Ventilatory Function in Adult With TOF

The goal of this clinical trial is to learn if combined inspiratory muscle training and aerobic exercise can improve ventilatory function in adults with repaired Tetralogy of Fallot (TOF). It will also learn if exercises work to raise functional capacity and Quality of life (QoL) . The main questions it aims to answer is:

* Dose combined inspiratory muscle training and aerobic exercise (study group) improve ventilatory function in adults with repaired (TOF) more than aerobic exercise only (control group)? * Can combine inspiratory muscle training and aerobic exercise (study group) raise functional capacity and (QoL) in adults with repaired (TOF) more than aerobic exercise only (control group)?

Researchers will compare between combination of inspiratory muscle training and aerobic exercise on one group and the aerobic exercise only on other group, on ventilatory function, functional capacity and (QoL) on adults with repaired TOF.

Participants will:

On study group , participants will perform respiratory muscle training in addition to moderate intensity aerobic exercise for 6 weeks. 3 times/week

On controlled group , participants will perform moderate intensity aerobic exercise for 6 weeks. 3 times/week.

all participants will test ventilatory function , functional capacity and will answer a survey questions about their quality of life before and after training
