Aging is discouraging! Are you suggesting you'd do better with a more

sedentary lifestyle? Your 10% CRON is not going to keep you safe here.

This just goes to show the folly of " jogging a mile one day per week "

to remain fit. Challenge is the key! Without physical challenge your

physical abilities will insideously decay. I suspect a few here are

unappreciative of these facts!

Let's take this to heart shall we (pun intended:)

" Post hoc analyses of the longitudinal data in the athletes based on

the training regimens over the follow-up period demonstrated that the

seven individuals who continued to train vigorously ( " high training " )

had no significant decline in VO2max "

A comparison of longitudinal changes in aerobic fitness in older

endurance athletes and sedentary men.

Katzel LI, Sorkin JD, Fleg JL.

Department of Medicine, Division of Gerontology, University of

land School of Medicine, Geriatrics Research Education and

Clinical Center, Baltimore, land, USA.

OBJECTIVES: To compare the longitudinal changes in maximal aerobic

capacity (VO2max) in healthy middle aged and older athletes and

sedentary men. DESIGN: A cohort study with mean follow-up of 8.7 years

(range 4.0-12.8). SETTING: Outpatient research at a tertiary hospital.

PARTICIPANTS: Forty-two healthy, middle aged, and older athletes

(initial age 64 +/- 1 year) and 47 healthy sedentary men of comparable

age recruited for research studies. MEASUREMENTS: VO2max during a

maximal treadmill test. RESULTS: At baseline, the cross-sectional

rates of decline in VO2max with age (slope) were virtually identical

in the athletes and sedentary men (-0.42 versus -0.43 mL x kg(-1) x

min(-1) x year(-1)). At follow-up, the VO2max had declined by 11.9 +/-

1.1 mL x kg(-1) x min(-1) (22%) in the athletes, a crude average rate

of -1.4 +/- 0.14 mL x kg(-1)x min(-1) x year(-1). By comparison, the

VO2max declined by 4.4 +/- 0.6 mL x kg(-1) x min(-1) (14%) in the

sedentary men, a crude average rate of change of -0.48 +/- 0.07 mL x

kg(-1) x min(-1) x year(-1). Therefore, the observed absolute rate of

longitudinal decline in VO2max in the athletes was triple that of the

sedentary men (P= .001) and significantly greater than the decline

predicted by their baseline cross-sectional data (P= .001). Post hoc

analyses of the longitudinal data in the athletes based on the

training regimens over the follow-up period demonstrated that the

seven individuals who continued to train vigorously ( " high training " )

had no significant decline in VO2max (0.28% change in VO2max per

year). By contrast, the VO2max declined by 2.6% per year in the

" moderate training " group (N=21), 4.6% per year in the " low training "

group (N=13), and 4.7% per year in the two individuals who developed

cardiovascular disease. CONCLUSION: The longitudinal decline in VO2max

in older male endurance athletes is highly dependent upon the

continued magnitude of the training stimulus. The majority of the

athletes reduced their training levels over time, resulting in

longitudinal reductions in VO2max two to three times as large as those

predicted by cross-sectional analyses or those observed longitudinally

in their sedentary peers.
