SummaryVariations in heart rate during exercise correlate with changes of exercise intensity and may be measured directly by radiotelemetry and continuous ECG recording. The heart rate can also be recorded in the memory of a microcomputer, which can be carried on the wrist as easily as a watch. The device has a transmitter and a receiver.By recording the heart rate during a training session or a segment of training, and calculating the average of the heart rate and comparing this average to… 

HEART RATE RECOVERY CHANGES FOR HIGH CLASS CANOE SPRINT ATHLETES DURING DIFFERENT TRAINING PERIODS

To evaluate the improvements of the heart regeneration rate and the functional condition of the athletes over the time period of 4 years, 12 high class flat-water kayakers took part in this study.

Heart rate during sleep: implications for monitoring training status.

It was found that on an individual basis the minimum heart rate during sleep varied by about 8 beats·min(-1), which needs to be considered when changes in heart rate that may occur with changes in training status are interpreted.

Endurance Exercise Intensity Determination in the Rehabilitation of Coronary Artery Disease Patients

The aim of this review is to describe the available methods for endurance exercise intensity determination in the rehabilitation of CAD patients, accompanied with their disadvantages, validity and reproducibility.

Heart Rate Does Not Reflect the %VO2max in Recreational Runners during the Marathon

P pacing during a marathon according to heart rate zones is not recommended and learning about the relationship between running sensations during training and racing using RPE is optimal.

VALIDATION OF SMARTPHONE FREE HEART RATE MONITORING APPLICATION DURING TREADMILL EXERCISE

ABSTRACT Objective: The number of people participating in leisure sports activities and amateur competitions has been rising sharply. Free smartphone heart rate monitoring applications are readily

HEART RATE AS A MEASURE OF EXERCISE INTENSITY IN SOCCER

There is no consensual definition of HRmax, but the relative HR is considered a god estimate of the exercise intensity (Eint) for athletes, as well as for non-athletes, and the lack of a reliable measurement protocol is pointed out.

Heart rate prescriptions from performance and anthropometrical characteristics.

The use of age alone seems too imprecise for exactly driven aerobic training prescriptions, and a minor improvement can be achieved by use of HRmax supplemented by age using a multiple regression model.

Is Continuous ECG Recording on Heart Rate Monitors the Most Expected Function by Endurance Athletes, Coaches, and Doctors?

In cases where arrhythmia was suspected, the value of the HRM’s ability to record ECGs during training by athletes and coaches increased, and continuous ECG recording during training will significantly improve the safety of athletes.

INDIVIDUALIZATION OF EXERTION WHILE MONITORING FUNCTIONAL STATE DURING EXERCISING

Comparison of calculated HR values recommended for individualization of endurance training workloads while taking into account the HR at real or relative rest found significant difference was found when comparing the averaged values of HR obtained at the real and relative states.

Regulating oxygen uptake during high-intensity exercise using heart rate and rating of perceived exertion.

Results suggest using both HR and RPE are effective at reducing the slow component of .VO2 that occurs during high-intensity exercise.

Comparison of Heart Rates Measured by ECG and Microcomputer

Both methods for measuring heart rate were found equally suitable: a microcomputer worn on the wrist and an ECG; for analyzing intensity of training.

Tape Recordings of the ECG of Active Men: Limitations and Advantages of the Holter‐Avionics Instruments

If records are made with subjects under constant observation and stop-watch timed, they can yield significant data on phenomena of rate, rhythm, and conduction, under a variety of circumstances and over long periods of time; but changes in the shape of the ST segment and T wave must be interpreted with great caution because of distortions produced by the recording system and by changes in position and activity.

A PRACTICAL METHOD OF ESTIMATING AN INDIVIDUAL'S MAXIMAL OXYGEN INTAKE

It is shown that the individual variability of maximum heart rate round the mean for the population is sufficiently small to use the moan in a routine test procedure without the introduction of largo errors.

Lactate in blood, mixed skeletal muscle, and FT or ST fibres during cycle exercise in man.

The ratio muscle:blood lactate was greater than one at all power outputs and increased most markedly at the power output closest to that eliciting 4 mmol x 1(-1) blood lactate (WOBLA).

Exercise Prescription by Heart Rate and Met Methods.

The authors challenge methods of measuring exercise capacity based on mets or target heart rate. The most accurate criterion may be a percentage of maximum functional heart rate.
