A Study of Heart - Rate in Difference Phase of Aerobic Dance for People in Lampang Province

Abstract

This research is to investigate the heart rate during various periods whilst practicing aerobics. The research was done by means of Polar Team. Subjects involved are a group of women practicing aerobic dance in a group of women that practice aerobic dance in the city district of Lampang Province. They are aged between 20 - 64 years old with a total of 90 subjects. They don't have any history of congenital diseases or symptoms of muscle injuries or other parts. The group was divided up into 3 groups; a group of aged 35 years and under, a group aged 36 - 45 years and a group aged 46 years and over.

The results of were found that;

1. The value of the average of the maximum heart rate during the period of warm up , aerobic exercise, and cool down for the 35 years and under group came to 95.92 beat/min., 139.04 beat/min, and 127.76 beat/min. The 36 - 45 years old group came to 96.17 beat/min., 132.90 beat/min, and 120.77 beat/min. The 46 years old and over group came to 96.43 beat/min., 129.43 beat/min, and 120.87 beat/min.


2. The average percentage of the maximumn heart rate during the period of warm up , aerobic exercise, and cool down for the 35 years and under group was 50.01, 72.49 and 66.61 HRmax The 36 - 45 years old group came to 54.04, 74.70, and 67.89 HRmax. The 46 years old and over group came to 57.72, 77.32, and 72.18? HRmax.

The aerobic dancing in the present consists of groups of aerobic dancer with different aged and physical health but had to do the activity same at the time. From the research it was found that the 46 years old and over group had a highest average heart rate during the period of aerobic than the other groups. So normally these groups should receive a shorter period of training compared to the other groups. The average percentage of the maximum heart rate during the cool down period of the aerobic dancing was high in the all three groups. From these average values of the heart rate whilst in the training zone aren't in harmony with the objective of the aerobic during the cool down period.

In order to exercise correctly by dancing aerobic it is necessary to study the format of aerobic dance so that the different periods are suitable for each age group and physical

health.
