Masuremnt of Heart Rat : Heart rate is number of contractions done by heart in one minute. The resting or basal heart rate is 72 beats per minute. The heart rate increases due to various factors but exercise or physical activity makes it to increase very fast in short period. The intensity (speed of work); volume (duration of work) also brings lot of variation in heart rate. For example :
(a) When we are at complete rest —> heart rate is approx. 72 beats/min.
(b) When we are walking —> heart rate is approx. 100 beats/min.
© When we are jogging —> heart rate is approx. 120 to 140 beats/min.
(d) When we are fast running —>heart rate is approx. 160 to 180 beats/min.
(e) When we are fast running for longer duration —> heart rate is approx. 200 and above beats/min.
Manual procedure to note heart rate : In this procedure the index finger is slightly placed over any of the arteries like at wrist (Radial artery), at elbow (Brachial artery) at neck (Jugular or Carotid artery), at groin (Femoral artery). Feel the pulse putting slight pressure by the finger. Notice and count this for 15 seconds and then multiply the counted beats by 4, this will be the heart rate of an individual in one minute.
