Pain and discomfort discourages morbidly obese women from exercising.
2003 MAY 8 - (NewsRx.com & NewsRx.net) -- by Maria G. Essig, MS, ELS, senior medical writer - Obese women, especially those severely obese, are limited in their ability to exercise by discomfort and pain as well as by extra weight and lack of fitness, according to a report in the Scandinavian Journal of Medicine and Science in Sports.
"The aim of this study was first, to assess the presence of medical conditions that might interfere with walking; second, to assess the differences in walking capacity, perceived exertion and physical complaints between lean, obese and morbidly obese women; and third, to identify anthropometric, physical fitness and physical activity variables that contribute to the variability in the distance achieved during a 6-minute walk test in lean and obese women," reported Maria Hulens and colleagues at UZ Gasthuisberg and the Katholieke Universiteit Leuven in Belgium.
The investigators recruited measured weight, height, body composition (by bioelectrical impedance), isokinetic concentric quadriceps strength (Cybex), and peak oxygen uptake (peakVO[subscript]2, by bicycle ergometer) in 300 female volunteers who were either overweight/obese (n=85, BMIgreater than or equal to27.5 kg/m[superscript]2), morbidly obese (n=133, BMIgreater than or equal to35.0 kg/m[superscript]20, or lean (n=82, BMI
The overweight/obese and morbidly obese subjects were significantly more likely than the lean women to report conditions such as skin friction, urinary stress incontinence, varicose veins, foot static problems, a need for insoles, knee pain, low back pain, and hip arthritis (p
By the end of the 6-minute walk test, the morbidly obese women were more likely than the overweight/obese or lean women to report shortness of breath (9.1% vs 4.7% and 0%, respectively; p
The researchers found that 75% of the difference in walking distance could be accounted for by BMI, peak VO[subscript]2, quadriceps muscle strength, age, and TV viewing time or sports participation.
"These data suggest that in contrast with lean women, walking ability of obese women is hampered not only by overweight, reduced aerobic capacity and a sedentary life style, but also by perceived discomfort and pain," ...
