The article presents an of the study "Exercise related changes in uteroplacental bloodflow as assessed by Doppler ultrasound at 85 percent maximum age predicted heart rate." It investigates the effect of maternal exercise on maternal and fetal circulations using Doppler ultrasound as well as find ...
This study investigated the accuracy of age-predicted equations to predict heart rate maximum (HRmax) in a college-age sample and establish efficacy of short-duration anaerobic capacity tests to determine the actual HRmax. A criterion HRmax (CHRmax) was obtained from 96 (52 men and 44 women, ...

The equations used by this calculator to determine your maximum heart rate are shown below.Classic: Maximum Heart Rate (beats/minute) = 220 - Age Tanaka: Maximum Heart Rate (beats/minute) = 208 - (0.7 x Age)Tanaka, H., Monhan, K.D., Seals, D.G., Age-predicted maximal heart rate ...
recommends an intensity of 55% to 90% of maximum heart rate (or age predicted maximum heart rate) for 20-60 minutes to obtain an improvement in cardiovascular efficiency and to help prevent the development of chronic lifestyle related disorders such as heart disease and Type II Diabetes (2000...
Secondary criteria were also applied to verify the maximal effort, such as an attainment of age-predicted maximum heart rate and/or a respiratory exchange... GE Duncan,ET Howley,BN Johnson - 《Med Sci Sports Exerc》 被引量: 500发表: 1997年 ...
When subjects reached 80% of their cycle ergometer age-predicted maximum heart rate, the test was terminated. Exercise and five-minute recovery heart rate data were collected. A ramp protocol with expired gas analysis was used to measure actual VO 2 max. Multiple regression analysis was ...
For each subject, straight line equation was derived by method of least squares using heart rate as predictor and oxygen consumption as criterion variable. Finally VO2was then extrapolated to the “age predicted maximal heart rate” to obtain the maximal aerobic capacity (VO2max) of the individua...
Results: There was a significant difference between directly measured maximum HR and predicted maximum HR (P < 0.01). There was no significant relationship between these variables. Bland-Altman analysis indicated that there was measurement bias (+4.7) and large limits of agreement (+26.7 and -...
Six hundred patients with HF in New York Heart Association (NYHA) functional class I-III underwent both CPX and 6 MWT and, through multivariable linear regression analysis, we defined several predictive models to define estMWR@CPX. Results The best model included 6 MWT, sex, age, weight, ...
