The blood pressure response of older XXXX to maximum and sub-maximum strength testing.

@entity1 @entity11559 @entity299
Strength testing is commonly used to determine the muscular strength of older individuals participating in a resistance training program. The purpose of this study was to non-invasively examine and compare the blood pressure (BP) and @entity299 ( @entity299 ) response of maximum and sub-maximum strength tests in older @entity1 . Twenty-four healthy @entity1 aged 70-80 yr were recruited for the study. @entity1 completed a 1 repetition maximum (RM) strength test and four days later a sub-maximum strength test on an incline squat. Systolic blood pressure (SBP), diastolic blood pressure ( @entity11559 ) and @entity299 were measured by plethysmography during and immediately after the strength tests. SBP, @entity11559 and @entity299 were (P<0.001) higher during the 1RM and sub-maximum strength tests compared to resting values. Twenty seconds post 1RM, SBP and @entity299 were higher than resting values. Twenty seconds post sub-maximum strength testing SBP and @entity11559 were lower (P<0.02) and @entity299 (P<0.001) was higher than resting values. SBP, @entity11559 and @entity299 were higher (P<0.001) during sub-maximum strength testing compared to 1RM testing. Twenty seconds post testing, SBP and @entity11559 were @entity299 was higher (P<0.001) for the sub-maximum strength tests compared to the 1RM. The results of our study demonstrate that sub-maximum strength testing resulted in greater changes in BP and @entity299 compared to 1RM strength testing. The lower cardiovascular stress experienced during the 1RM shows that this may be a safer method of testing compared to sub-maximum strength testing in @entity1 aged 70-80 yr.
