When watts become heat<\/p>\n
In cycling, watts usually mean one thing: the power a rider puts into the pedals.<\/p>\n
But the body is not a perfectly efficient engine. A relatively small part of the energy becomes mechanical power that moves the bike forward. A much larger part becomes heat inside the body.<\/p>\n
\u201cFor every calorie the human body burns, roughly 20 percent becomes mechanical watts, creating forward motion. Around 80 percent goes to other processes \u2014 especially heat,\u201d Bu explains.<\/p>\n
For elite athletes pushing 300 to 400 watts on the bike, that can mean producing 1500 to 2000 watts of heat. In simple terms: almost like having a heater on full power inside the body.<\/p>\n
That is the heat CORE helps make visible. The sensor estimates core body temperature indirectly by combining skin temperature with heat flux \u2014 a measure of how much heat is moving from the body towards the skin and out to the environment.<\/p>\n
\u201cCORE measures heat flux, or thermal watts, together with the temperature of the skin. When you combine those two, you can estimate the body\u2019s core temperature quite accurately,\u201d Bu says.<\/p>\n
If the rider cannot get rid of heat efficiently, performance starts to drop. Heart rate rises, the effort feels harder, and the body may eventually force the rider to reduce the power on the bike.<\/p>\n","protected":false},"excerpt":{"rendered":"When watts become heat In cycling, watts usually mean one thing: the power a rider puts into the…\n","protected":false},"author":2,"featured_media":797269,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[445],"tags":[49,48,635,82],"class_list":["post-797268","post","type-post","status-publish","format-standard","has-post-thumbnail","category-cycling","tag-ca","tag-canada","tag-cycling","tag-sports"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/797268","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=797268"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/797268\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/797269"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=797268"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=797268"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=797268"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
