Rate Of Decline

We tested the hypothesis that the age-related decline in maximal aerobic capacity, as measured by maximal oxygen uptake (V˙o 2 max), is greater in Hispanic than in Caucasian women. We studied 146 healthy sedentary women aged 20–75 yr: 53 Hispanic (primarily of Mexican descent) and 93 Caucasian (non-Hispanic white). The groups did not differ in mean age, body mass, percent body fat, estimated physical activity-related energy expenditure, or education-based socioeconomic status (SES). During maximal exercise, respiratory exchange ratio, rating of perceived exertion, and percent predicted maximal heart rate were similar across age and ethnicity, suggesting equivalent maximum voluntary efforts in all subjects. V˙o 2 max(ml · kg−1 · min−1) was inversely related to age ( P < 0.01) in Caucasian ( r =−0.68) and Hispanic ( r = −0.61) women. The absolute rate of decline in V˙o 2 maxwith age was the same in the two groups (−0.31 ml · kg−1 · min−1 · yr−1). The relative rate of decline (% from age 25 yr) also was similar in the Caucasian (−9.0%) and Hispanic (−9.2%) women. When subjects of all ages were pooled, mean levels ofV˙o 2 max were similar in the two groups (∼28 ml · kg−1 · min−1). These results, the first to our knowledge in Hispanics, indicate that mean levels of V˙o 2 max, as well as the rate of decline in V˙o 2 max with age, are similar in healthy sedentary Hispanic and Caucasian women of similar SES. Thus it does not appear that Hispanic ethnicity per se modulates maximal aerobic capacity in this population.

Fitzgerald, Margaret D., Hirofumi Tanaka, Zung V. Tran, and Douglas R. Seals. Age-related declines in maximal aerobic capacity in regularly exercising vs. sedentary women: a meta-analysis. J. Appl. Physiol. 83(1): 160–165, 1997.—Our purpose was to determine the relationship between habitual aerobic exercise status and the rate of decline in maximal aerobic capacity across the adult age range in women. A meta-analytic approach was used in which mean maximal oxygen consumption (V˙o 2 max) values from female subject groups (ages 18–89 yr) were obtained from the published literature. A total of 239 subject groups from 109 studies involving 4,884 subjects met the inclusion criteria and were arbitrarily separated into sedentary (groups = 107; subjects = 2,256), active (groups = 69; subjects = 1,717), and endurance-trained (groups = 63; subjects = 911) populations.V˙o 2 max averaged 29.7 ± 7.8, 38.7 ± 9.2, and 52.0 ± 10.5 ml ⋅ kg−1 ⋅ min−1, respectively, and was inversely related to age within each population ( r = −0.82 to −0.87, all P < 0.0001). The rate of decline inV˙o 2 max with increasing subject group age was lowest in sedentary women (−3.5 ml ⋅ kg−1 ⋅ min−1⋅ decade−1), greater in active women (−4.4 ml ⋅ kg−1 ⋅ min−1⋅ decade−1), and greatest in endurance-trained women (−6.2 ml ⋅ kg−1 ⋅ min−1 ⋅ decade−1) (all P < 0.001 vs. each other). When expressed as percent decrease from mean levels at age ∼25 yr, the rates of decline inV˙o 2 max were similar in the three populations (−10.0 to −10.9%/decade). There was no obvious relationship between aerobic exercise status and the rate of decline in maximal heart rate with age. The results of this cross-sectional study support the hypothesis that, in contrast to the prevailing view, the rate of decline in maximal aerobic capacity with age is greater, not smaller, in endurance-trained vs. sedentary women. The greater rate of decline inV˙o 2 max in endurance-trained populations may be related to their higher values as young adults (baseline effect) and/or to greater age-related reductions in exercise volume; however, it does not appear to be related to a greater rate of decline in maximal heart rate with age.

Tanaka, Hirofumi, Christopher A. DeSouza, Pamela P. Jones, Edith T. Stevenson, Kevin P. Davy, and Douglas R. Seals. Greater rate of decline in maximal aerobic capacity with age in physically active vs. sedentary healthy women. J. Appl. Physiol. 83(6): 1947–1953, 1997.—Using a meta-analytic approach, we recently reported that the rate of decline in maximal oxygen uptake (V˙o 2 max) with age in healthy women is greatest in the most physically active and smallest in the least active when expressed in milliliters per kilogram per minute per decade. We tested this hypothesis prospectively under well-controlled laboratory conditions by studying 156 healthy, nonobese women (age 20–75 yr): 84 endurance-trained runners (ET) and 72 sedentary subjects (S). ET were matched across the age range for age-adjusted 10-km running performance. Body mass was positively related with age in S but not in ET. Fat-free mass was not different with age in ET or S. Maximal respiratory exchange ratio and rating of perceived exertion were similar across age in ET and S, suggesting equivalent voluntary maximal efforts. There was a significant but modest decline in running mileage, frequency, and speed with advancing age in ET.V˙o 2 max(ml ⋅ kg−1 ⋅ min−1) was inversely related to age ( P < 0.001) in ET ( r = −0.82) and S ( r = −0.71) and was higher at any age in ET. Consistent with our meta-analysic findings, the absolute rate of decline inV˙o 2 max was greater in ET (−5.7 ml ⋅ kg−1 ⋅ min−1 ⋅ decade−1) compared with S (−3.2 ml ⋅ kg−1 ⋅ min−1 ⋅ decade−1; P < 0.01), but the relative (%) rate of decline was similar (−9.7 vs −9.1%/decade; not significant). The greater absolute rate of decline inV˙o 2 max in ET compared with S was not associated with a greater rate of decline in maximal heart rate (−5.6 vs. −6.2 beats ⋅ min−1 ⋅ decade−1), nor was it related to training factors. The present cross-sectional findings provide additional evidence that the absolute, but not the relative, rate of decline in maximal aerobic capacity with age may be greater in highly physically active women compared with their sedentary healthy peers. This difference does not appear to be related to age-associated changes in maximal heart rate, body composition, or training factors.

On the basis of cross-sectional data, we previously reported that the absolute, but not the relative (%), rate of decline in maximal oxygen consumption (V˙o 2 max) with age is greater in endurance-trained compared with healthy sedentary women. We tested this hypothesis by using a longitudinal approach. Eight sedentary (63 ± 2 yr at follow-up) and 16 endurance-trained (57 ± 2) women were reevaluated after a mean follow-up period of 7 yr. At baseline,V˙o 2 max was ∼70% higher in endurance-trained women (48.1 ± 1.7 vs. 28.1 ± 0.8 ml · kg−1 · min−1 · yr−1). At follow-up, body mass, fat-free mass, maximal respiratory exchange ratio, and maximal rating of perceived exertion were not different from baseline in either group. The absolute rate of decline inV˙o 2 max was twice as great ( P < 0.01) in the endurance-trained (−0.84 ± 0.15 ml · kg−1 · min−1 · yr−1) vs. sedentary (−0.40 ± 0.12 ml · kg−1 · min−1 · yr−1) group, but the relative rates of decline were not different (−1.8 ± 0.3 vs. −1.5 ± 0.4% per year). Differences in rates of decline in V˙o 2 max were not related to changes in body mass or maximal heart rate. However, among endurance-trained women, the relative rate of decline inV˙o 2 max was positively related to reductions in training volume ( r = 0.63). Consistent with this, the age-related reduction inV˙o 2 max in a subgroup of endurance-trained women who maintained or increased training volume was not different from that of sedentary women. These longitudinal data indicate that the greater decrease in maximal aerobic capacity with advancing age observed in middle-aged and older endurance-trained women in general compared with their sedentary peers is due to declines in habitual exercise in some endurance-trained women. Endurance-trained women who maintain or increase training volume demonstrated age-associated declines in maximal aerobic capacity not different from healthy sedentary women.

Based on cross-sectional data, we recently reported that, in contrast to the prevailing view, the rate of decline in maximal oxygen consumption (V˙o 2 max) with age is greater in physically active compared with sedentary healthy women. We tested this hypothesis in men using a meta-analytic study ofV˙o 2 max values in the published literature. A total of 242 studies (538 subject groups and 13,828 subjects) met the inclusion criteria and were arbitrarily separated into sedentary (214 groups, 6,231 subjects), active (159 groups, 5,621 subjects), and endurance-trained (165 groups, 1,976 subjects) populations. Body fat percent increased with age in sedentary and active men ( P < 0.001), whereas no change was observed in endurance-trained men.V˙o 2 max was inversely and strongly related to age within each population ( r = −0.80 to −0.88, all P < 0.001) and was highest in endurance-trained and lowest in sedentary populations at any age. Absolute rates of decline inV˙o 2 max with age were not different ( P > 0.05) in sedentary (−4.0 ml ⋅ kg−1 ⋅ min−1 ⋅ decade−1), active (−4.0), and endurance-trained (−4.6) populations. Similarly, there were no group differences ( P > 0.05) in the relative (%) rates of decline inV˙o 2 max with advancing age (−8.7, −7.3, and −6.8%/decade, respectively). Maximal heart rate was inversely related to age within each population ( r = −0.88 to −0.93, all P < 0.001), but the rate of age-related reduction was not different among the populations. There was a significant decline in running mileage and speed with advancing age in the endurance-trained men. The present cross-sectional meta-analytic findings do not support the hypothesis that the rate of decline inV˙o 2 max with age is related to habitual aerobic exercise status in men.

To determine the relation between habitual endurance exercise status and the age-associated decline in maximal aerobic capacity [i.e., maximal O2consumption (V˙o2 max)] in men, we performed a well-controlled cross-sectional laboratory study on 153 healthy men aged 20–75 yr: 64 sedentary and 89 endurance trained.V˙o2 max(ml · kg−1· min−1), measured by maximal treadmill exercise, was inversely related to age in the endurance-trained ( r = −0.80) and sedentary ( r = −0.74) men but was higher in the endurance-trained men at any age. The rate of decline inV˙o2 maxwith age (ml · kg−1· min−1) was greater ( P < 0.001) in the endurance-trained than in the sedentary men. Whereas the relative rate of decline inV˙o2 max(percent decrease per decade from baseline levels in young adulthood) was similar in the two groups, the absolute rate of decline inV˙o2 maxwas −5.4 and −3.9 ml · kg−1· min−· decade−1in the endurance-trained and sedentary men, respectively.V˙o2 maxdeclined linearly across the age range in the sedentary men but was maintained in the endurance-trained men until ∼50 yr of age. The accelerated decline inV˙o2 maxafter 50 yr of age in the endurance-trained men was related to a decline in training volume ( r = 0.46, P < 0.0001) and was associated with an increase in 10-km running time ( r = −0.84, P < 0.0001). We conclude that the rate of decline in maximal aerobic capacity during middle and older age is greater in endurance-trained men than in their sedentary peers and is associated with a marked decline in O2pulse.

Individually, exercise and the drug metformin have been shown to prevent or delay type 2 diabetes. Metformin mildly inhibits complex I of the electron transport system and may impact aerobic capacity in people exercising while taking metformin. The purpose of the study was to evaluate the effects of metformin on maximal aerobic capacity in healthy individuals without mitochondrial dysfunction. Seventeen healthy, normal-weight men (n = 11) and women (n = 6) participated in a double-blind, placebo-controlled, cross-over design. Peak aerobic capacity was measured twice using a continuous, incrementally graded protocol; once after 7–9 d of metformin (final dose = 2000 mg/d) and once with placebo, with 1 week between tests. The order of the conditions was counterbalanced. Peak oxygen uptake (VO2 peak), heart rate (HR), ventilation (VE), respiratory exchange ratio (RER), rating of perceived exertion (RPE), and test duration were compared across conditions using paired t tests with the R statistical program. VO2 peak (–2.7%), peak heart rate (–2.0%), peak ventilation (–6.2%), peak RER (–3.0%), and exercise duration (–4.1%) were all reduced slightly, but significantly, with metformin (all p < 0.05). There was no effect of metformin on RPE or ventilatory breakpoint. Correlations between the decrement in VO2 peak and any of the other outcome variables were weak (r2 < 0.20) and not significant. Short-term treatment with metformin has statistically significant, but physiologically subtle, effects that reduce key outcomes related to maximal exercise capacity. Whether this small but consistent effect is manifested in people with insulin resistance or diabetes who already have some degree of mitochondrial dysfunction remains to be determined.

Due to physiological and morphological differences, younger and older athletes may recover differently from training loads. High-intensity interval training (HIIT) protocols are useful for studying the progression of recovery. It was the objective of this study to determine age differences in performance and recovery following different HIIT protocols. Methods: 12 younger (24.5 ± 3.7 years) and 12 older (47.3 ± 8.6 years) well-trained cyclists and triathletes took part in this study. Between the age groups there were no significant differences in relative peak power to fat-free mass, maximal heart rate (HR), training volume, and VO2max-percentiles (%). Participants performed different HIIT protocols consisting of 4 × 30 s Wingate tests with different active rest intervals (1, 3, or 10 min). Peak and average power, lactate, HR, respiratory exchange ratio (RER), subjective rating of perceived exertion (RPE), and recovery (Total Quality Recovery scale, TQR) were assessed. Results: During the different HIIT protocols, metabolic, cardiovascular, and subjective recovery were similar between the two groups. No significant differences were found in average lactate concentration, peak and average power, fatigue (%), %HRmax, RER, RPE, and TQR values between the groups (p > 0.05). Conclusion: The findings of this study indicate that recovery following HIIT does not differ between the two age groups. Furthermore, older and younger participants displayed similar lactate kinetics after the intermittent exercise protocols.

Purpose:To assess the distribution of exercise intensity in long-distance recreational athletes (LDRs) preparing for a marathon and to test the hypothesis that individual perception of effort could provide training responses similar to those provided by standardized training methodologies.Methods:Seven LDRs (age 36.5 ± 3.8 y) were followed during a 5-mo training period culminating with a city marathon. Heart rate at 2.0 and 4.0 mmol/L and maximal heart rate were used to establish 3 intensity training zones. Internal training load (TL) was assessed by training zones and TRIMPi methods. These were compared with the session-rating-of-perceived-exertion (RPE) method.Results:Total time spent in zone 1 was higher than in zones 2 and 3 (76.3% ± 6.4%, 17.3% ± 5.8%, and 6.3% ± 0.9%, respectively; P = .000 for both, ES = 0.98, ES = 0.99). TL quantified by session-RPE provided the same result. The comparison between session-RPE and training-zones-based methods showed no significant difference at the lowest intensity (P = .07, ES = 0.25). A significant correlation was observed between TL RPE and TL TRIMPi at both individual and group levels (r = .79, P < .001). There was a significant correlation between total time spent in zone 1 and the improvement at the running speed of 2 mmol/L (r = .88, P < .001). A negative correlation was found between running speed at 2 mmol/L and the time needed to complete the marathon (r = –.83, P < .001).Conclusions:These findings suggest that in recreational LDRs most of the training time is spent at low intensity and that this is associated with improved performances. Session-RPE is an easy-to-use training method that provides responses similar to those obtained with standardized training methodologies.

Fifteen well-trained master endurance athletes [62.0 +/- 2.3 (SE) yr] and 14 sedentary control subjects (61.4 +/- 1.4 yr) were reevaluated after an average follow-up period of approximately 8 yr to obtain information regarding the effects of physical activity on the age-related decline in maximal O2 uptake capacity (VO2max). The master athletes had been training for 10.2 +/- 2.9 yr before initial testing and continued to train during the follow-up period. The sedentary subjects' VO2max declined by an average of 3.3 ml.kg-1.min-1 (33.9 +/- 1.7 vs. 30.6 +/- 1.6, P less than 0.001) over the course of the study, a decline of 12% per decade. In these subjects maximal heart rate declined 8 beats/min (171 vs. 163) and maximal O2 pulse decreased from 0.20 to 0.18 ml.kg-1.beat (P less than 0.05). The master athletes' VO2 max decreased by an average of 2.2 ml.kg-1.min-1 (54.0 +/- 1.7 vs. 51.8 +/- 1.8, P less than 0.05), a 5.5% decline per decade. The master athletes' maximal heart rate was unchanged (171 +/- 3 beats/min) and their maximal O2 pulse decreased from 0.32 to 0.30 ml.kg-1.beat (P less than 0.05). These findings provide evidence that the age-related decrease in VO2max of master athletes who continue to engage in regular vigorous endurance exercise training is approximately one-half the rate of decline seen in age-matched sedentary subjects. Furthermore our results suggest that endurance exercise training may reduce the rate of decline in maximal heart rate that typically occurs as an individual ages.
