| Abstract: |
This work has been conducted on 40 male subjects classified into two groups:* Group I: Athletic Control group (20) subjects aged 21.7 ± 3.5 y. free from any real illness and are Zagazig University top performance athletes.* Group II: Retired athletes group (20) subjects age 33.5 +2.5 y. old free from any real illness who were top performance athletes and retired from athletic training at least 4 years ago asretired athletes group.* Athletes and retired athletes groups were subjected to thefollowing procedures.1- Complete medical examination. 2- Resting ECG.3- Resting Doppler -echocardiography.4- Treadmill exercise stress testing (Bruce protocol). 5- Post exercise Doppler-echocardiography.HR, BL.p, Mean BLP, LYEDd, LYESd, FS% , LYM, LYEDY , LVESY, SY, EF%, PFY, MAFYA, E, A, E/A, were measured for both groups pre-and post exercise:* Resting HR for athletic group was 60,45 +7.688 beat/min mm.Hg and post exercise it was 79.1 +3.9 mm.Hg which showed a highly statistically significant differnece. (P < 0.01). Resting D.BL.p for both groups showed a highly statistically significant difference for the athletic group. (P<O.Ol). Post exercise D.BL.p for both groups showed no statistically significant difference between both groups. (t:l.38, P< 0.1). Resting mean BL.p for the athletic group was 87.65 +5.36 mm.Hg and post exercise it was 103 +3.85 mm.Hg which showed a highly statistically significant value. (P < 0.01). Resting Mean BL.p for the retired athletes group was 92.1 +3.39 mm.Hg which showed a highly statistically significant difference (P < 0.01). Resting Mean BL.p for both groups showed a highly statistically significant difference for the athletic group. (P<O.Ol). Post exercise Mean BL.p for both groups showed no statistically significant difference. (t: 1.38 , P < 0.1). 1- Ecocardiographic Parameters: Systolic function parameters Resting LVEDd for the athletic group was 5.4 +0.22 ern and post exercise it was 5.445 +0.21 cm which showed no significant difference. (t: 1.48 , P < 0.1). Resting L VEDd for the retired athletes group was 5.1 +0.232 cm and post exercise it was 5.18 +0.2 Col which showed a highly statistically significant
