ro, perhaps you should do your research before slagging iDave off for his lack of knowledge........
Of continue and make yourself look even more foolish.

if your chum would care to post links to the relevant research papers i'll gladly wolf down some humble pie. 2 seconds on pubmed produced this:

Abstract
Energy requirements of military personnel (Soldiers, Sailors, Airmen, and Marines) have been measured in garrison and in field training under a variety of climatic conditions. Group mean total energy expenditures for 424 male military personnel from various units engaged in diverse missions ranged from 13.0 to 29.8 MJ (3109-7131 kcal) per day. The overall mean was 19.3+/-2.7 MJ (mean+/-SD) (4610+/-650 kcal) per day measured over an average of 12.2 days (range 2.25-69 days). For the 77 female military personnel studied, mean total energy expenditures for individual experimental groups ranged from 9.8 to 23.4 MJ (2332-5597 kcal) per day, with an overall mean of 11.9+/-2.6 MJ (2850+/-620 kcal) per day, measured over an average of 8.8 days (range 2.25-14 days). Women, presumably due to their lower lean body mass, resting metabolic rate, and absolute work rates, had lower total energy expenditures. Combat training produced higher energy requirements than non-combat training or support activities. Compared to temperate conditions, total energy expenditures did not appear to be influenced by hot weather, but tended to be higher in the cold or high altitude conditions.

he last sentence on the abstract appears relevant
keep up ro, the article you cite is not related to comparing total calorie cost of running in heat and running in aircon environment.
thermal stress causes excess energy consumption in the recovery period - agreed?
you can undertake more total work in cooler temperatures, but for the same given exercise workload, overall you will burn more calories exercising in heat due to the energy cost of returning the body to homeostasis post-exercise.
which of course you know......
I warned you troll boy, but you always know best, smart arse.
and of course you'll also know that the whole EPOC/ homeostasis argument is coming under increasing re-evaluation by our Finnish chums who did most of the work in the first place. it was always questionable, and now it looks as though the basic science may be skewed. i'm more pissed than you are, 'cos EPOC was a very promising concept and SUUNTO's implementation of it very elegant.
i know [i]what[/i] you're suggesting, but you're coming at it from the wrong angle. to suggests that calorie expenditure for a given running speed on a treadmill is increased during exercise in heat vs exercise in cold is simply incorrect, and [i]you[/i] know it 🙂
Re: sharks.
Climate change and the construction of ports and wharves near the shore are cited as major reasons for the arrival of sharks at these beaches.
