NMR and MS techniques have proven to be very useful analytical tools, especially in the last decade, in the metabolomic/metabonomic study of animal and plant organisms. The combination of these orthogonal techniques allows the analysis of matrices looking for target or non-target compounds and obtaining information on the molecular structure of the compounds involved in their discrimination. In addition, quantitative results can be obtained with a minimum sample preparation time. On the other hand, the positive results generated by the use of inspiratory muscle training (IMT) in active and non-active healthy individuals have made this type of intervention one of the most studied in the last decades. IMT has already been used as an integral part of cardiorespiratory rehabilitation in individuals with respiratory muscle weakness and currently appears as an alternative to improve the athletic performance of amateur and elite athletes by reducing the sensation of dyspnea in these individuals. In addition, regular physical activity is one of the main tools for healthy aging, so the metabolic characterization of active and sedentary aging can elucidate metabolic changes during the aging process.
