Relationship Between %Heart Rate Reserve And %VO2 Reserve During Elliptical Crosstrainer Exercise.
The primary purpose of the study was to determine the relationships between %HRR vs. %VO2R and %HRR vs. %VO2max during maximal elliptical crosstrainer (ECT) exercise. A secondary aim was to compare the %HRR vs. %VO2R and %HRR vs. %VO2max relationships between maximal ECT and treadmill (TM) exercise. Adult subjects (n = 48) completed a maximal exercise test on the ECT, with a subgroup (N = 24) a...
متن کاملPre-exercise food and heart rate during submaximal exercise.
The heart rates of 20 movement studies students were measured during multi-stage cycle ergometer tests. The tests were repeated on five occasions following the ingestion of different pre-exercise meals and the results compared. A glucose solution taken three hours prior to the exercise (G3) resulted in the lowest heart rates at each work rate. The highest heart rates at each work rate were reco...
متن کاملVO2 Reserve vs. Heart Rate Reserve During Moderate Intensity Treadmill Exercise.
VO2 and heart rate (HR) are widely used when determining appropriate training intensities for clinical, healthy, and athletic populations. It has been shown that if the % reserve (%R) is used, rather than % of max, HR and VO2 can be used interchangeably to accurately prescribe exercise intensities. Thus, heart rate reserve (HRR) can be prescribed if VO2 reserve (VO2R) is known. Therefore, the p...
متن کاملAnalysis of Heart Rate Variability During Submaximal Exercise
an increased mortality in patients recovering from myocardial infarction. The effects that physiologic perturbations such as exercise have on this heart rate variability have not been investigated. Therefore, heart rate variability was measured throughout a submaximal exercise test in 36 mongrel dogs with healed anterior myocardial infarctions. The amplitude of the respiratory component (0.24-1...
متن کاملThe Heart Rate during a Simple Exercise.
Simple exercise tolerance tests, such as stepping on and off a stool a given number of times and noting the effect on the pulse rate, have long been used in medical practice. Almost invariably, however, the pulse rate is taken before and after, owing to the difficulty of counting it during the exercise. This may be overcome by means of a recording apparatus such as that of Bell and Knox (1938);...
