A small drop of blood, obtained by a finger prick (for running tests) or an earlobe prick (for cycling tests), is sufficient to determine the lactate level. This gives us a very good picture of the degree to which you are endurance-trained and how you train. In other words: it is a way to evaluate your endurance (&#8216;fitness&#8217;), and therefore also to see how much progress you can still make and what kind of training you need for that.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img data-recalc-dims=\"1\" decoding=\"async\" width=\"636\" height=\"516\" data-attachment-id=\"126\" data-permalink=\"https:\/\/backtobasicsinsports.com\/nl\/energy-delivery-during-testing\/\" data-orig-file=\"https:\/\/i0.wp.com\/backtobasicsinsports.com\/wp-content\/uploads\/2026\/08\/Energy-delivery-during-testing.jpg?fit=636%2C516&amp;ssl=1\" data-orig-size=\"636,516\" data-comments-opened=\"1\" data-image-title=\"Energy delivery during testing\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/backtobasicsinsports.com\/wp-content\/uploads\/2026\/08\/Energy-delivery-during-testing.jpg?fit=636%2C516&amp;ssl=1\" fetchpriority=\"low\" src=\"https:\/\/i0.wp.com\/backtobasicsinsports.com\/wp-content\/uploads\/2026\/08\/Energy-delivery-during-testing.jpg?resize=636%2C516&#038;ssl=1\" alt=\"\" class=\"wp-image-126\" srcset=\"https:\/\/i0.wp.com\/backtobasicsinsports.com\/wp-content\/uploads\/2026\/08\/Energy-delivery-during-testing.jpg?w=636&amp;ssl=1 636w, https:\/\/i0.wp.com\/backtobasicsinsports.com\/wp-content\/uploads\/2026\/08\/Energy-delivery-during-testing.jpg?resize=300%2C243&amp;ssl=1 300w, https:\/\/i0.wp.com\/backtobasicsinsports.com\/wp-content\/uploads\/2026\/08\/Energy-delivery-during-testing.jpg?resize=600%2C487&amp;ssl=1 600w\" sizes=\"(max-width: 636px) 100vw, 636px\" \/><\/figure>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-container-core-group-is-layout-d4fc447e wp-block-group-is-layout-constrained\">\n<div data-wp-context=\"{ &quot;autoclose&quot;: false, &quot;accordionItems&quot;: [] }\" data-wp-interactive=\"core\/accordion\" role=\"group\" class=\"wp-block-accordion is-layout-flow wp-block-accordion-is-layout-flow\">\n<div data-wp-class--is-open=\"state.isOpen\" data-wp-context=\"{ &quot;id&quot;: &quot;accordion-item-3&quot;, &quot;openByDefault&quot;: false }\" data-wp-init=\"callbacks.initAccordionItems\" data-wp-on-window--hashchange=\"callbacks.hashChange\" class=\"wp-block-accordion-item is-layout-flow wp-block-accordion-item-is-layout-flow\">\n<h3 class=\"wp-block-accordion-heading has-icon has-icon-right has-medium-font-size\" style=\"font-style:normal;font-weight:600\"><button aria-expanded=\"false\" aria-controls=\"accordion-item-3-panel\" data-wp-bind--aria-expanded=\"state.isOpen\" data-wp-on--click=\"actions.toggle\" id=\"accordion-item-3\" type=\"button\" class=\"wp-block-accordion-heading__toggle\"><span class=\"wp-block-accordion-heading__toggle-title\">2.

A cardiological examination can only be carried out by a heart specialist, where the heart will be examined more thoroughly than in a sports medical check-up. The latter is broader in scope: for example, the musculoskeletal system is also assessed, with a view to injury prevention. A cardiologist is, however, also qualified to issue sports medical certificates (e.g. your cycling licence).<br><br><strong>A cardiological examination<\/strong>&nbsp;is strongly&nbsp;<strong>recommended<\/strong>&nbsp;in the following situations:<br>1\/ cardiac&nbsp;<em>history&nbsp;<\/em>of the athlete (is there a known heart condition?)<br>2\/ cardiac&nbsp;<em>symptoms during\/shortly after exercise<\/em>&nbsp;(chest pain, shortness of breath or dizziness during exertion, palpitations, fainting)<br>3\/ cardiac&nbsp;<em>risk factors&nbsp;<\/em>(smoking, high blood pressure, high cholesterol, diabetes, age &gt;35 years)<br>4\/&nbsp;<em>cardiac event in first-degree relatives<\/em>&nbsp;(heart attack, cardiac arrest, sudden death)<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-container-core-group-is-layout-d4fc447e wp-block-group-is-layout-constrained\">\n<div data-wp-context=\"{ &quot;autoclose&quot;: false, &quot;accordionItems&quot;: [] }\" data-wp-interactive=\"core\/accordion\" role=\"group\" class=\"wp-block-accordion is-layout-flow wp-block-accordion-is-layout-flow\">\n<div data-wp-class--is-open=\"state.isOpen\" data-wp-context=\"{ &quot;id&quot;: &quot;accordion-item-9&quot;, &quot;openByDefault&quot;: false }\" data-wp-init=\"callbacks.initAccordionItems\" data-wp-on-window--hashchange=\"callbacks.hashChange\" class=\"wp-block-accordion-item is-layout-flow wp-block-accordion-item-is-layout-flow\">\n<h3 class=\"wp-block-accordion-heading has-icon has-icon-right has-medium-font-size\" style=\"font-style:normal;font-weight:600\"><button aria-expanded=\"false\" aria-controls=\"accordion-item-9-panel\" data-wp-bind--aria-expanded=\"state.isOpen\" data-wp-on--click=\"actions.toggle\" id=\"accordion-item-9\" type=\"button\" class=\"wp-block-accordion-heading__toggle\"><span class=\"wp-block-accordion-heading__toggle-title\">8.
