Effects of a topical lotion containing aminophylline, caffeine, yohimbe, l l ‐carnitine, and gotu kola on thigh circumference, skinfold thickness, and fat mass in sedentary females

摘要

Abstract Background and objective Topical aminophylline, caffeine, yohimbe, l ‐carnitine, and gotu kola ( Centella asiatica ) may aid in reducing body fat. Lipoxyderm? contains these ingredients and was used to test if fat loss of the thigh, in conjunction with a low intensity exercise program and restricted calorie intake, was enhanced via the topical application of this lotion. Methods This was a double‐blind, placebo‐controlled, within‐group study that investigated the effects of Lipoxyderm? on thigh fat mass, circumference, and skinfold thickness. Seven participants underwent pre/post‐exercise testing for weight, bilateral thigh circumference/skinfold thickness, and body composition/thigh fat mass assessment via dual‐energy X‐ray absorptiometry. Participants followed a hypocaloric diet, walked 150?minutes/wk, and were randomly assigned to apply a placebo to one leg and Lipoxyderm? to their other leg for 28?days. Separate two‐way mixed factorial repeated measures ANOVAs were used to compare the effects of Lipoxyderm? to the placebo on thigh circumference, skinfold thickness, and fat mass. Results A significant time x group interaction was found for thigh circumference ( F 1,6 ?=?18.2, P ?=?0.005), skinfold thickness ( F 1,6 ?=?14.6, P ?=?0.009), and fat mass ( F 1,6 ?=?37.1, P ?=?0.001). Conclusions A twice‐daily topical application of Lipoxyderm? for 28?days compared to a placebo combined with a walking program and a restricted caloric intake is more effective at reducing thigh circumference (1.2 vs 0.8?cm), thigh skinfold thickness (3.7 vs 2.0?mm), and thigh fat mass (100.0?g vs 57.3?g).
