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.

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.

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.

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.

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.

Introduction: Given the importance of adapting workers' physical and mental capabilities to their job needs, measuring their ability to work, maintaining, and upgrading, it has become an essential task. This study aimed to investigate WAI and its relationship with VO2max at one of the cement companies. Materials and Methods: This cross-sectional study was conducted among 130 employees of a cement company in Iran in 2018. For data collection, the WAI, Queens's test for maximum oxygen consumption, and a questionnaire designed by researchers (socio-demographic and work-related factors) were used. SPSS 21 was used to analyze the data.  Results: The results showed that the mean ± standard deviation of WAI in staff was 39.35 ± 4.64. Among the demographic and related variables, sports activity (P > 0.04) and sleep quality (P < 0.001), and work experience (P> 0.046) were significantly correlated with WAI. There was a significant positive correlation between the mean score of WAI and Vo2max (r = 0.21, p < 0.05). Regression modeling showed that Vo2max was the only significant predictor of WAI. Conclusion: According to the results of the study, to control and enhance the ability of the staff of the study, occupational intervention programs should focus on improving sleep quality and increased exercise. Also, considering the positive relationship of Vo2max to the WAI of the surveyed staff, it is recommended to select suitable employees in terms of aerobic capacity according to the workload of the job.

Studies assessing changes in maximal aerobic capacity (V˙o 2 max) associated with aging have traditionally employed the ratio ofV˙o 2 max to body weight. Log-linear, ordinary least-squares, and weighted least-squares models may avoid some of the inherent weaknesses associated with the use of ratios. In this study we used four different methods to examine the age-associated decline inV˙o 2 max in a cross-sectional sample of 276 healthy men, aged 45–80 yr. Sixty-one of the men were aerobically trained athletes, and the remainder were sedentary. The model that accounted for the largest proportion of variance was a weighted least-squares model that included age, fat-free mass, and an indicator variable denoting exercise training status. The model accounted for 66% of the variance inV˙o 2 max and satisfied all the important general linear model assumptions. The other approaches failed to satisfy one or more of these assumptions. The results indicated thatV˙o 2 max declines at the same rate in athletic and sedentary men (0.24 l/min or 9%/decade) and that 35% of this decline (0.08 l ⋅ min−1 ⋅ decade−1) is due to the age-associated loss of fat-free mass.
