Relationship between evening exercise and late- night exercise towards heart rate recovery (HRR) and sleep quality among male young adult in UiTM Pahang / Nor Balqis Mohd Said

The purpose of this study is to investigate the relationship between evening
exercise (EE) and late-night exercise (LNE) towards heart rate recovery (HRR) and
sleep quality among male young adult in UiTM Pahang. There were 30 male young
adult that actively playing futsal who participated in the study, age ranging from 18
to 23 years old. The subject were equally divided into two groups; evening exerciser
(n=15), late-night exerciser (n=15). The dependent variable in the study was Three
Minutes Step Test and answering the Pittsburgh Sleep Quality Index (PSQI)
questionnaire. Based on Independent T-test analysis and Pearson's Correlation, there
is significant different (p<0.05) was showed between heart rate after two minutes
testing and sleep quality among evening and late-night group of exercises [M =
84.40, SD = 6.197], [M = 77.60, SD = 6.599]. Also, there is significant different
between heart rate after testing and heart rate after two minutes testing among
evening and late-night exercises [HR after testing: (EE) M = 106.80, SD = 8.841]
[(LNE) M= 118.80, SD = 4.057], [HR after two minutes testing (EE) M= 84.40, SD
= 6.197] [(LNE) M = 77.60, SD = 6.599]. However, there is also resulted correlation
between heart rate recovery and sleep quality [p<0.05]. Different time of exercises
were analyzed as to examine level of heart rate recovery (HRR) and sleep quality
among male young adult. Another finding in this study were there is correlation
between HRR and sleep quality. In current study, there is significant relationship
between evening and late-night exercises towards HRR and sleep quality. In this
study, it can be concluded that, any of time in a day could involved in a physical
