Abstrakt:	The aim of the study was to evaluate the application of global longitudinal strain (GLS) and myocardial work (MW) at rest and during exercise in healthy sedentary or trained participants, to test their ability to improve echocardiographic information and to complement prescribing exercise, cardiac screening, or rehabilitation programs. Methods: Thirty healthy males were divided into three groups of 10, sedentary (G1), resistance (G2) and power (G3) athletes, underwent a standard clinical evaluation protocol and exercise stress testing echocardiography. Results: During stress, all showed increased left ventricular ejection fraction and mitral annulus tissue Doppler (E'). G1 showed a decrease in left atrial volume (LAVi) as opposed to an increase in G3. E/E 'a decrease in G2, unlike the increase in G3. All groups showed increase of Strain (GLS average AV, Longitudinal LS, Medio-Basal MB Apical AP), global constructive work (GCW), and Global wasted work. G1 showed increase for global work efficiency, G2 and G3 for global work index (GWI). G3 showed a greater variation of E/E', LAVi, GWI and GCW compared to G1 and G2, greater of GLS AV, LS-AP compared to G2. Only G3 showed differences for GLS AV versus LS-AP. The relative regional strain ratio showed a greater value in G3 versus G1 at the end of stress compared to rest. Conclusions: The new echocardiographic applications to study the physiological adaptation could open new perspectives for the diagnostic and therapeutic development through the prescription of personalized exercises and screening and follow-up of the early pathological changes of the athlete's heart. Competing Interests: There are no conflicts of interest. (Copyright: © 2022 Journal of Cardiovascular Echography.)
