Effects of Chronic Overload Training and Aging on Left Ventricular Systolic Function

Abstract: To examine the effects of age and chronic overload training on left ventricular systolic function during static exercise, Doppler echocardiography studies were performed in 14 young (28 ± 6 years) and 10 older (51 ± 3 years) weight lifters and also in 14 young (29 ± 6 years) and 10 older (52 ± 1.1 years) normal individuals during upright dead-lift isometric exercise, at 30% of maximal voluntary contraction for 3 min. At rest, older weight lifters demonstrated impaired left ventricular systolic function as comp… Show more

“…However, MacDougall and associates (24) suggest that resistance exercise is analogous to a series of static contractions that are performed dynamically. The major-ity of research comparing the effects of age on acute resistance exercise has been conducted using isometric exercise (36, 38-40, 43, 49, 51); this is probably due to the more stringent control associated with this exercise and with the ability to generalize this type of exercise to everyday tasks (38).…”

“…In order to determine the acute HR response to training status and age, Sagiv et al (38) compared the effect of a dead lift isometric exercise, held at 30% of MVC for 3 minutes, in 14 younger (28 Ϯ 6.0 years) and 10 older (51 Ϯ 3.0 years) weight lifters and in 14 younger (29 Ϯ 6.0 years) and 10 older (52 Ϯ 1.1 years) ''normal'' individuals. During the dead lift, all subjects increased mean peak HR significantly from rest (but not between groups), attaining values of 94.2 Ϯ 8, 96.0 Ϯ 9, 90.4 Ϯ 10, and 89.1 Ϯ 6 bpm for the young normals, young weight lifters, old normals, and old weight lifters, respectively.…”

“…Thus, light to moderate resistive training exercise can be considered safe for low-risk cardiac patients. Even the risk of developing compromised left ventricular function is less during a workout against weight resistance compared to that in conventional clinical aerobic exercise test [7]. Circuit weight training is an approach for strength development especially designed for the elderly.…”
