Increased dietary saturated fat intake is negatively associated with compliance to exercise regimen and improvement in fitness parameters.. Journal of Federation of American Societies for Experimental Biology. 257.4.Interpretive Summary:
                                Technical Abstract: Objective: To determine if dietary intake of fat, sugar, and/or
sodium affects improvement in aerobic fitness in response to a 6-
mo endurance and resistance training program in peri-menopausal
women. Methods:18 women aged 42-52y underwent a 6 mo
exercise intervention, working out 6 d/wk, 60 min/d. The program
included daily aerobic activity at = 50% of heart rate (HR) reserve
and resistance exercises 3 d/wk. Monitors recorded heart rate
during exercise, and compliance was calculated using the number
of minutes above prescribed HR. Improvement in aerobic capacity
was measured by VO2max at beginning and end of the study.
Dietary intake was assessed by 24h recalls on 4 d in 1stmonth and 4
d in 6thmonth of intervention. Results: Total fat and saturated fat
intake were negatively correlated to compliance (r = -0.501,
p<0.05; r = -0.511, p<0.05), but added sugars, total sugars and
sodium intake were not. Change in VO2max was positively
correlated with compliance (r = 0.475 p<0.05), but negatively
associated with saturated fat intake (r= -0.416, p<0.05).
Conclusion: Our observations on the association of fat intake,
exercise compliance, and fitness improvement warrant further
investigation to understand their underlying biological and
behavioral significance.
