Abstract
In a recent study, we have shown that the commercially available Cold Buster (TRADEMARK) Sports bar, purported to improve cold resistance, did not do so in our subjects exposed to relatively severe cold test. One possible explanation for our conflicting results is that our metabolic rate (M) was too high for the possibly small thermogenic effect of the bar to be measureable. The goal of the study was therefore to re-evaluate, under milder conditions, the influence of the Cold Buster (TRADEMARK) on heat balance (heat debt = heat production - heat losses) and body temperatures. Eight semi-nude fasted subjects were exposed to the cold (3h at rest, 10C, <0.4 m.s-1 wind) on two occasions following the ingestion of either a placebo (100 ml water) or a Cold Buster (TRADEMARK) (all feedings at min 0 and 90). The results confirm previous data where the ingestion of the Cold Buster (TRADEMARK) Sports bar did not alter heat production, heat losses, heat debt or even body temperatures, and extend these observations to a mild cold stress. Although the Cold Buster (TRADEMARK) enhanced CHO mobilization and oxidation, the phenomenon occured entirely at the expense of mobilization and oxidation of lipids. Taken together, these studies do not provide any evidence to support a recommendation for the use of the Cold Buster (TRADEMARK) Sports bar.
