Previousresearchhas demonstrate that HIIE ( such as sprints ) increase the charge per unit of acute lipide oxidisation both before and after exercise , signify it uses up more fuel and continue to “ burn fat ” after we ’ve hold back moving . Lipid oxidation rate is also increase when exercise incold temperatures . The squad on the enquiry wanted to examine the effects of cold stress during HIIE on the metabolism of lipoid , both during exercise and after . They asked 11 moderately fit heavy adults between 18 and 30 geezerhood of age to practice eventide HIIE Roger Huntington Sessions in intermediate ( 21 ° C/ 70 ° F ) and cold ( 0 ° C/32 ° F ) environments . The HIIE session demand 10 sets of 60 - second frantic cycling ( the sort you might do inthis scenario ) interspersed with 90 - second of cycling at a easy step , taking sampling to assess lipid oxidation both before and immediately after the exercise . The observe daybreak , they were treated to a high - fat breakfast after which indirect calorimetry was used to evaluate the player ’s metamorphosis . Blood sample distribution were also collected to look at change in the metabolites line up in our pedigree .
The analyses break that during acuate exercise ( mad cycling ) lipid oxidisation increased by 113 percent in dusty environments compared to warmer cycling sports stadium . While it might seem that a bleep test on an sparkler rink could be the way forward for maximum burning at the stake electric potential , lipid compactness , blood plasma insulin and triglyceride concentrations did n’t vary much between the fond and frigid conditions . In fact , the researchers actually concluded that HIIE in the common cold had less favorable outcomes for after - breakfast lipide and glycemic responses compared to those who had worked out in the warmer control .
“ We observed that high - intensity interval exercise in a cold environment does exchange acute metamorphosis liken to a thermoneutral environment , ” wrote the researcher in the discipline . “ However , the addition of a cold stimulant was less favorable for postprandial metabolic responses the following day . "
It ’s important to observe this was a small written report with just 11 participants , so it ’s strong to draw strong conclusions without further report into how temperature bear on metabolic process during exercising . It ’s also important to remember , however , that exercise in the cold can only glean benefit if you don’tdie of hypothermia . Something to grudge on before you gorunning laps of a near - icy lake .
