Table 1. RMS Value based on subjects weight group
Male Female
Weight Range RMS value Weight Range RMS value
Under 55 kg 30.83 Under 40 kg 29.04
55 ~ 65 kg 42.97 40 ~ 50 kg 29.28
65 ~ 75 kg 53.95 50 ~ 60 kg 35.17
Over 75 kg 61.47 60 ~ 75 kg 45.18
The RMS values increases, when subject’s weight increases for both genders (Table 1).
In the case of male, significant difference has been found in the RMS values for: over
75 kg & under 55 kg (p-value=0.002); over 75 kg & 55~65 kg (p-value=0.011); and
over 75 kg & 65~75 kg (p-value=0.095). In the case of female, there is no significance
difference in RMS values between under 40 kg & 40~50 kg; and under 40 kg & over 50
kg (p-value=0.158).
Table 2. RMS Value based on subjects age group
Male Female
Age Group RMS value Age Group RMS value
10 ~ 20 60.94 10 ~ 20 42.97
20 ~ 50 44.27 Over 20 31.09
Over 60 39.41
The RMS values increases, when subject’s age group decreases for both genders (Table
2). For male, there was large significant difference in RMS values between 10’s &
20~50’s (p-value=0.037); 10’s & over 60’s (p-value=0.034) and no significant
difference between 20~50’s & over 60’s. For female, significant difference in RMS
values between 10’s & over 20’s (p-value=0.038).
Table 3. Time and level of exercise
Exercise time per week Level of exercise Exercise time per week Level of exercise
0 1 9 ~ 10 6
1 ~ 2 2 11 ~ 12 7
3 ~ 4 3 13 ~ 14 8
5 ~ 6 4 15 ~ 16 9
7 ~ 8 5 17 ~ 18 10
Exercise time/week was calculated by multiplying exercise time/day with number of
days exercised/week labeled from 0 to 18 and level of exercise labeled from 1 to 10
(Table 3). The range of exercise days 0 to 6; exercise time less than 1 hour and more
than 3 hours was assigned point from 1 to 3.
The RMS values increases, when subject’s exercise level increases (Table 4). For male,
significant difference in RMS values between 1~4 & 5~10 (p-value=0.041). For female,
significant difference in RMS values between 1~3 & 4~10 (p-value=0.095).
