A new study has found that braving the cold maybe a good way to help burn off some fat.
The research was carried out by scientists at Canada’s Laurentian University and focused on high-intensity interval training(HIIT). This format has grown in popularity of late due to the fat-burning benefits it brings, and the team set out to explore how temperature might influence its effects.
The study involved 11 overweight adults who took part in two HIIT sessions a week apart. One of these was carried out in a “thermoneutral” environment with temperatures of around 70 °F(21℃),and the other at a cold 32 °F(0℃). The sessions consisted of 10 separate cycling race at 90 percent effort lasting one minute, followed by 90-second “recovery” periods of cycling at30 percent intensity.
After each session, the participants cooled down by gently cycling or walking, ate a nutrition bar before going to sleep and enjoyed a high-fat breakfast the morning after. During these sessions, the scientists monitored skin temperature, core body temperature, heart rate and the amount of oxygen. Blood samples were also drawn to help calculate fat burning rates following the breakfast the next day.
“The present study found that high-intensity exercise in the cold increased lipid oxidation (脂质氧化) by 358 percent in comparison to high-intensity exercise in a thermoneutral environment,”the team writes.
The authors also note that the idea that cold temperatures help us burn more fat during exercise will need further investigation (调查), though the first-of-a-kind study does indicate it’s a possibility worth pursuing.
