PREVENTION \u00b7 FLUID BALANCE<\/span><\/p>\n<\/div> The sensation of thirst decreases by up to 40 percent with age. Those who stand on the court for four hours in the summer can build up a two-liter deficit without noticing. The consequence is measurable: score drop from the 13th hole, loss of concentration, shorter putts.<\/span><\/p><\/div><\/div><\/div><\/div><\/div> I<\/span>In a hot June tournament, I took almost an hour longer on the back nine than the front nine. My score went up by seven strokes. I thought I was tired. In reality, I was dehydrated \u2013 and didn't realize it because I wasn't thirsty. Three weeks later, I did it right: two water bottles, a sip every two holes, even without thirst. The score collapse disappeared.<\/p>\n<\/div> Hydration is one of those topics that seems self-explanatory. Drink when you're thirsty, and everything will be fine. This doesn't apply to people over 60. The part of the brain that signals thirst becomes less sensitive with age. You can accumulate a deficit of a liter without receiving any signal.<\/p>\n<\/div> Even a deficit of two percent of body weight (1.6 liters for an 80 kg player) reduces cognitive performance by 10 to 20 percent. Reaction times become longer, attention spans shorter, and decision quality decreases.<\/p>\n On the green, this means: Putt reading becomes less accurate. On the fairway: Club selection becomes less certain. During the swing: Stability decreases, the last ten percent of speed is lost \u2014 distance gone. This isn't \u201ebeing tired.\u201d It's a measurable, biological deficit.<\/p>\n<\/div> \u221215 % cognitive performance with a 2 % body weight deficit \u2014 exactly what happens during a 4-hour summer run without drinking.<\/strong><\/p>\n<\/div> Three biological changes occur together after age 60: The kidneys concentrate urine less effectively (more fluid loss), the perception of thirst decreases, and the body's water reserve diminishes. While a 30-year-old has 60 percent water content, a 70-year-old often has only 50 percent. This means the same fluid loss has a greater relative effect.<\/p>\n<\/div> \u2014 German Sport University Cologne, Senior Sports Study 2024<\/p>\n<\/div> Four mistakes build up the deficit without you noticing. They are all easy to avoid\u2014if you know them.<\/p>\n A double espresso before the round has a diuretic effect \u2014 approximately 1.5 times the amount of fluid goes through the kidney. Those who get up early and start right away already have a deficit on the first [hole].<\/p>\n The classic mistake. For older adults, the sensation of thirst often doesn\u2019t set in until there is a 3 % deficit\u2014that is, after their performance has already declined. Hydration must be proactive.<\/p>\n Drinking two large glasses of water on the 9th hole is too late and too much. The stomach can only process about 200 ml of water every 15 minutes. The rest just goes right through.<\/p>\n<\/div> Hyponatremia\u2014the dangerous dilution of blood sodium\u2014occurs in senior sports. Drinking three liters of pure water on a run risks cramps, confusion, and in extreme cases, unconsciousness. The solution: add a pinch of salt or an electrolyte powder. Clear water alone is not enough for more than two hours of exertion.<\/p>\n On this page<\/p>\n<\/div> The sensation of thirst decreases by up to 40 percent with age. Anyone who spends four hours on the court in summer can unknowingly build up a deficit of two liters \u2014 a drop in score from the 13th hole.<\/p>","protected":false},"author":1,"featured_media":47,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[231,13,6],"tags":[32,18,21,33,17],"class_list":["post-387","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-ausruestung-schlaeger","category-senioren-golf-gesundheit","category-putt-und-lag","tag-32","tag-gesundheit-praevention","tag-hydration","tag-score-verbesserung","tag-senior-golf"],"_links":{"self":[{"href":"https:\/\/senior-golf.de\/en\/wp-json\/wp\/v2\/posts\/387","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/senior-golf.de\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/senior-golf.de\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/senior-golf.de\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/senior-golf.de\/en\/wp-json\/wp\/v2\/comments?post=387"}],"version-history":[{"count":3,"href":"https:\/\/senior-golf.de\/en\/wp-json\/wp\/v2\/posts\/387\/revisions"}],"predecessor-version":[{"id":1139,"href":"https:\/\/senior-golf.de\/en\/wp-json\/wp\/v2\/posts\/387\/revisions\/1139"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/senior-golf.de\/en\/wp-json\/wp\/v2\/media\/47"}],"wp:attachment":[{"href":"https:\/\/senior-golf.de\/en\/wp-json\/wp\/v2\/media?parent=387"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/senior-golf.de\/en\/wp-json\/wp\/v2\/categories?post=387"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/senior-golf.de\/en\/wp-json\/wp\/v2\/tags?post=387"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Hydration after 60 \u2014 four mistakes on the round.<\/span><\/h1>\n<\/div>
