摘要：McHugh AN, Esco MR, Bloomquist BE, Williford HN. Effects of a Low Volume Recreational Jogging Program on CardiovascularAutonomic Control. JEPonline 2012;15(4):18-25. The purpose of this study was to determine if a 2-day per week jogging program would improve heart rate variability (HRV) and heart rate recovery (HRR) after 7 weeks in young adults with low cardiovascular fitness levels. Sixteen males (n=7) and females (n=9) participated in the study. At baseline, resting HRV was measured during a 5-minute period. Normalized high frequency power (HFnu) and the low frequency to HF ratio (LF:HF) were recorded. A maximal graded exercise test was completed to determine HRR at 1 min (HRR1) and 2 min (HRR2) post-exercise. After baseline testing, the subjects began a 2-day per week recreational jogging program for a 7-week period. At the end of the 7 weeks, the subjects returned to the laboratory for post-testing measures. There were no significant changes (P>0.05) in either HFnu (Pre = 55.11 ± 7.60 ms2 , Post = 53.39 ± 8.17 ms2 ) or LF:HF (Pre = 0.58 ± 0.31, Post = 0.59 ± 0.25). There was also no significant change in HRR1 (Pre = 21.47 ± 10.78 beats·min-1 , Post = 21.60 ± 10.35 beats·min-1 , P>0.05). However, there was a small but significant increase in HRR2 (Pre = 38.00 ± 15.13 beats·min-1 , Post = 41.33 ± 13.79, P=0.048). A recreational jogging program of only 2 days per week did not significantly improve all markers of cardiovascularautonomic function.
