Cardio respiratory Fitness: Students were asked to refrain from
any vigorous intensity physical activity 24 hours prior to the day of
RWFT and report to the 400 meters track two hours after taking light
breakfast. They were instructed to walk as fast as possible for one
mile on the track. Time for completion was noted using stopwatch.
Followed by recording of number of pulse beat for 15 seconds from
brachial artery and multiplied by four to obtain one minute recovery
HR (beats/min). Body weight adjusted VO2
max (mL/ kg of body
weight/ min) score was calculated using the following equation
(18;19):
Girls: VO2
max = 139.168 – (0.88 X age in years) – (0.077 X weight
in lb.) – (3.265 X walk time in minutes) – (0.156 X heart rate).
boys: Add 6.318 to the equation for females above.
Absolute VO2
max is calculated by multiplying the VO2
max adjusted
for body weight by the corresponding body weight of the individual.
VO2
max adjusted for FFM is calculated by dividing the absolute
VO max by the corresponding FFM.
