Chronic Effects of exercise on cardiac measures<\/span><\/span><\/span><\/span><\/strong><\/p>\n\n

With regular training, stroke volume increases as the heart muscle around the left ventricle increases in size and strength. This means more blood is ejected from the left ventricle each beat. A s a result, resting heart rate reduces as the same amount of blood can be delivered to muscles in less beats.

The graph below shows the effect of training on exercise heart rates. You can see that the resting heart rate in the pre-training phase is lower in the trained athlete. The exercise training heart rate doesn\u2019t climb as high and levels off earlier in the trained athlete compared with the untrained. Finally, the trained athlete recovers far more quickly post exercise.<\/span><\/span><\/span><\/span><\/p>\n\t\t\t\n\t\t\n\t\n\n\n"},"subContentId":"041fc795-c9e2-4ee6-ad93-31081b04b248","metadata":{"contentType":"Text","license":"U","title":"Untitled Text"}},"alwaysDisplayComments":false,"backgroundOpacity":0,"displayAsButton":false,"buttonSize":"big","goToSlideType":"specified","invisible":false,"solution":""}],"slideBackgroundSelector":{}}],"keywordListEnabled":true,"globalBackgroundSelector":{},"keywordListAlwaysShow":false,"keywordListAutoHide":false,"keywordListOpacity":90},"override":{"activeSurface":false,"hideSummarySlide":false,"summarySlideSolutionButton":true,"summarySlideRetryButton":true,"enablePrintButton":false,"social":{"showFacebookShare":false,"facebookShare":{"url":"@currentpageurl","quote":"I scored @score out of @maxScore on a task at @currentpageurl."},"showTwitterShare":false,"twitterShare":{"statement":"I scored @score out of @maxScore on a task at @currentpageurl.","url":"@currentpageurl","hashtags":"h5p, course"},"showGoogleShare":false,"googleShareUrl":"@currentpageurl"}},"l10n":{"slide":"Slide","score":"Score","yourScore":"Your Score","maxScore":"Max Score","total":"Total","totalScore":"Total Score","showSolutions":"Show solutions","retry":"Retry","exportAnswers":"Export text","hideKeywords":"Hide sidebar navigation menu","showKeywords":"Show sidebar navigation menu","fullscreen":"Fullscreen","exitFullscreen":"Exit fullscreen","prevSlide":"Previous slide","nextSlide":"Next slide","currentSlide":"Current slide","lastSlide":"Last slide","solutionModeTitle":"Exit solution mode","solutionModeText":"Solution Mode","summaryMultipleTaskText":"Multiple tasks","scoreMessage":"You achieved:","shareFacebook":"Share on Facebook","shareTwitter":"Share on Twitter","shareGoogle":"Share on Google+","summary":"Summary","solutionsButtonTitle":"Show comments","printTitle":"Print","printIngress":"How would you like to print this presentation?","printAllSlides":"Print all slides","printCurrentSlide":"Print current slide","noTitle":"No title","accessibilitySlideNavigationExplanation":"Use left and right arrow to change slide in that direction whenever canvas is selected.","accessibilityCanvasLabel":"Presentation canvas.
