Abstract
Introduction: Heart rate variability (HRV) after physical workout showed an increase
in cardiac autonomic regulation. The measurement of recovery HRV after exercise is
extremely useful in giving valuable input of the heart regulation as well as its integrity.
These components were used as indicators to assess the magnitude of cardiac recovery
from exercise
Objectives: This study investigated the effects of 20-metre shuttle run in modulating
recovery HRV components in male university football players that measured low
frequency (LF), high frequency (HF), low frequency to high frequency (LF:HF) ratio at
pre, post-24, 48 and 72 hours after running.
Methods: Twenty participants were randomly assigned into intervention and control
group. Participants from intervention group performed 20 metre shuttles run while the
control group did not perform the run. Heart rate was recorded at pre-run, post-24, post-
48, and post-72 hours after running. The heart rates were analysed for HRV components
using Polar Flow and Kubios software. Differences between groups were analysed
using repeated measures analysis of variance (ANOV A). All data were expressed as
mean± SO. Significance difference was set at p <0.05.
Results: There was no significant difference between control and intervention group in
all three analysis for LF-peak frequency (p= 0.78), LF-power (p= 0.368) and LF n.u (p=
0.404). HF component also resulted no significance difference in all three analyses of
peak frequency (p=0.148), HF-power (p=0.326) and HF-n.u (p=0.192) between control
and intervention group at pre, post-24 hour, post-48 hour and post-72 hour after
running. There was also no significance difference found between control and
intervention group for LF:HF (p=0.457).
Conclusion: There was no significant difference recorded in the effects of 20-metre
shuttle run in modulating recovery HRV components in male football players of
Universiti Sains Malaysia.
