Rate Of Recovery

The kinetics of post-exercise heart rate (HR) and oxygen consumption (EPOC) was studied in 10 elite cyclists subjected to four laboratory cycle ergometer maximal exercises lasting 30, 90, 180 or 360 s. Heart rate and oxygen uptake (VO2) were recorded over a period of 6 min after the exercise. By applying the logit transformation to the recorded variables and relating them to the decimal logarithm of the recovery time, uniform single-phase courses of changes were shown for both variables in all subjects and exercises. This enabled computing half-recovery times (t½) for both variables. Half-time for VO2 negatively correlated with square root of exercise duration (within-subject r=–0.629, p<0.001), the total post-exercise oxygen uptake till t½ was thus constant irrespectively of exercise intensity. The method is simple and enables reliable comparisons of various modes of exercise with respect to the rate of recovery.

Background: Age-related change in autonomic nerves covers parasympathetic function decrease that hampers heart rate (HR) control.  The effective attempt to improve autonomic nervous function for elderly is routine exercise, however exercise duration among elderly is not always standardized. This study is aimed to compare the effect of different exercise duration to post-exercise Heart Rate Recovery (HRR) between two elderly groups with the same frequency, intensity, type criteria of routine exercise. Method: Method was cross-sectional study which compared exercise duration of standardized group (3x90 minutes/week) and unstandardized group (3x30 minutes/week). Group 1 was elders with standardized duration from Healthy Heart Club and Group 2 was elders who take unstandardized duration from Elderly Home in Bandung city. Each group consisted of 43 elders and data were collected in July-August 2019. After one hour of medium intensity exercise, all respondents were examined for resting HR (HRrest), maximum HR (HRmax), one minute post-exercise HR, and four minutes post-exercise HR. HRR was obtained by subtracting HRmax by one minute post-exercise HR and normal if  > 12 bpm. Analysis data was done by SPSS with Mann-Whitney U Test, Fisher Chi Square and Logistic regression. Result: Most of respondents were 60-69 years old and female. Respondents in unstandardized group were more low education, hypertension and smoking. The HRrest of both groups was categorized as normal but increased greater (30x/min)  in standardized group. The result showed a significant difference in comparation of median HRR (p=0.001) and number of normal and abnormal HRR (p=0.001) between both groups. Gender, smoking and standardized duration of exercise associated with abnormality of HRR, elders who take unstandardized duration have 12.7 times risk to get abnormal HRR. Conclusion: Routine exercise for elderly is recommended in standardized duration with minimal 150 minutes per week in order to increase post-exercise HRR.

Twenty-four male subjects aged 17–33 were given three direct tests of maximal oxygen uptake and one indirect test. The direct tests were those of Mitchell, Sproule, and Chapman (treadmill); Taylor, Buskirk, and Henschel (treadmill); and Åstrand (bicycle ergometer). The indirect test was the Åstrand-Ryhming nomogram (bicycle ergometer) employing heart rate response to submaximal work. In addition, the Johnson, Brouha, and Darling physical fitness test was administered. The two treadmill tests and the indirect test yielded significantly higher mean values than did the direct bicycle test. However no other significant differences in mean values occurred. Correlation coefficients between the various oxygen uptake tests as well as the fitness test were all found to be significant (.62–.83), i.e., greater than zero. No correlation obtained proved to be significantly greater than any other. The results indicate that direct treadmill tests, employing greater muscle mass, yield higher maximal oxygen uptake values (8%) than does the direct bicycle ergometer test. The Åstrand-Ryhming nomogram appears to produce a good estimation of maximal oxygen uptake, in a population unaccustomed to cycling. erobic capacity; exercise; heart rate Submitted on September 17, 1964
