An area that is often completely misunderstood, especially in <strong>boxing<\/strong> and high-end athletic training. Many people still think of endurance only in terms of classic marathon runners who shovel mountains of pasta into themselves the evening before. Complete nonsense.   <\/p>\n<p>Boxing is a high-intensity endurance sport. If you run out of breath in the ring after two rounds, the hardest punch in the world won&#8217;t do you any good. Without the right fuel in the tank, your performance will slump &#8211; this applies to sport just as much as it does to your focus in business.  <\/p>\n<p>Here are the <strong>3 most important key messages<\/strong> from my expert article for TK that you must use for yourself immediately:<\/p>\n<ul>\n<li><strong>The right timing<\/strong>: It&#8217;s not just about what you eat, but when. Strategic energy intake before exercise determines whether you fly or completely collapse during training. <\/li>\n<li><strong>Fluid controls reflexes<\/strong>: Dehydration kills your concentration and maximum strength long before you even feel really thirsty. No engine runs without electrolytes. <\/li>\n<li><strong>Regeneration after the punch<\/strong>: After training, your nutrient intake determines whether your body breaks down valuable muscle mass (catabolic state) or repairs itself optimally to make you fit for the next session.<\/li>\n<\/ul>\n<p>You can now find the complete, scientifically based article with all my nutrition tips and detailed strategies directly on the official TK portal.[\/vc_column_text][\/vc_column][\/vc_row][vc_row content_placement=&#8221;middle&#8221;][vc_column width=&#8221;2\/3&#8243; css=&#8221;.vc_custom_1712761651276{margin-top: 1.1em !important;margin-bottom: 0px !important;}&#8221;][vc_column_text css=&#8221;&#8221;]<\/p>\n<h4><b>Read my full expert article on Techniker Krankenkasse now<\/b><\/h4>\n<p>[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/3&#8243;]<div class=\"gem-button-container gem-button-position-inline thegem-button-6a5036147a7341302    \"  ><a class=\"gem-button gem-button-size-small gem-button-style-flat gem-button-text-weight-normal\" data-ll-effect=\"drop-right-without-wrap\" style=\"border-radius: 3px;\" onmouseleave=\"\" onmouseenter=\"\" href=\"https:\/\/www.tk.de\/techniker\/gesundheit-foerdern\/sport-und-bewegung\/training\/ernaehrung-im-ausdauersport-2215326\" target=\"_blank\">To the TK contribution<\/a><\/div> [\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Whether it&#8217;s a half marathon, triathlon or intensive boxing training &#8211; the right nutrition is the key to your best performance.
