ROBI SIKA ON NOVAK DJOKOVI\u0106: ATP medical director addresses the problems troubling the Serbian tennis player!"},"content":{"rendered":"\n<p class=\"wp-block-paragraph\"><strong><em>Dr. Robi Sika, medical director of the Association of Tennis Professionals<\/em><\/strong> <strong><em><a href=\"https:\/\/serbiantimes.info\/tag\/tenis\/\">tennis players<\/a>, addressed the problems faced by Novak \u0110okovi\u0107.<\/em><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sika points out that endurance does not suddenly decline when an athlete enters their thirties, but recovery efficiency decreases significantly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;The difference becomes apparent when you ask the body to sprint, stop, change direction, recover \u2013 and then repeat it a hundred times over several hours, and potentially again two days later. Recovery between points, between sets and between matches becomes less efficient,&#8221; Sika said, as reported by &#8220;The New York Times.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some of the conditions inherent to Grand Slam tournaments, such as best-of-five-set matches that can stretch into the night, only make the whole situation worse.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;Tendons become stiffer, joints and muscles have absorbed decades of strain, and minor injuries and degenerative changes accumulate. That can subtly change movement efficiency, so an older player may expend more energy performing the same movement,&#8221; Sika added.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Younger players can use up 85-90 percent of their energy reserves during demanding matches, while later in their careers that figure can approach 100 percent.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;I wouldn&#8217;t say that he vomits because he is older. I would say that recurring nausea can be a visible sign of how close the body is to its limit. And as the boundary between sustainable exertion and maximal exertion narrows with age, it can potentially be easier to reach that point,&#8221; Sika emphasized.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Let us recall that <a href=\"https:\/\/serbiantimes.info\/tag\/novak\/\">\u0110okovi\u0107<\/a> was eliminated in the first round of the <a href=\"https:\/\/serbiantimes.info\/tag\/usopen\/\">US Open<\/a> by Mariano Navone, showing visible signs of exhaustion along the way. The Serbian ace was eliminated in the first round of the US Open for the first time in his career, after winning his opening-round match 19 consecutive times.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><mark style=\"background-color:#FFFFFF;color:#d21414\" class=\"has-inline-color\">READ MORE: <\/mark><\/h4>\n\n\n\n<figure class=\"wp-block-embed is-type-wp-embed is-provider-serbiantimes-info wp-block-embed-serbiantimes-info\"><div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"wp-embedded-content\" data-secret=\"FzbrWG4WLR\"><a href=\"https:\/\/serbiantimes.info\/posle-492-dana-vucic-raspisao-vanredne-izbore-crta-tvrdi-da-drzavne-institucije-pomazu-sns-u-u-izbornoj-trci\/\">POSLE 492 DANA VU\u010cI\u0106 RASPISAO VANREDNE IZBORE: CRTA tvrdi da dr\u017eavne institucije poma\u017eu SNS-u u izbornoj trci!<\/a><\/blockquote><iframe loading=\"lazy\" class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; visibility: hidden;\" title=\"\u201ePOSLE 492 DANA VU\u010cI\u0106 RASPISAO VANREDNE IZBORE: CRTA tvrdi da dr\u017eavne institucije poma\u017eu SNS-u u izbornoj trci!\u201c \u2014 Serbiantimes.info\" src=\"https:\/\/serbiantimes.info\/posle-492-dana-vucic-raspisao-vanredne-izbore-crta-tvrdi-da-drzavne-institucije-pomazu-sns-u-u-izbornoj-trci\/embed\/#?secret=YJ3LXl6jSG#?secret=FzbrWG4WLR\" data-secret=\"FzbrWG4WLR\" width=\"500\" height=\"282\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe>\n<\/div><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><mark style=\"background-color:#FFFFFF;color:#d21414\" class=\"has-inline-color\">MORE TOPICS:<\/mark><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><a href=\"https:\/\/serbiantimes.info\/en\/we-wont-let-them-treat-us-like-tourists-drivers-from-bih-serbia-montenegro-and-macedonia-to-protest-tomorrow-threaten-border-blockades-if-brussels-does-not-back-down\/\" target=\"_blank\" rel=\"noopener\">\u201cWE WON\u2019T LET THEM TREAT US LIKE TOURISTS\u201d: Drivers from BiH, Serbia, Montenegro and Macedonia to protest tomorrow, threaten border blockades if Brussels does not back down!<\/a><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><a href=\"https:\/\/serbiantimes.info\/en\/with-the-money-of-citizens-who-have-no-water-cacak-spent-two-million-on-a-breskvica-concert-but-only-around-60-people-attended\/\" target=\"_blank\" rel=\"noopener\">WITH THE MONEY OF CITIZENS WHO HAVE NO WATER: \u010ca\u010dak spent two million on a Breskvica concert, but only around 60 people attended!<\/a><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><a href=\"https:\/\/serbiantimes.info\/en\/new-blow-to-education-government-preparing-a-law-that-will-punish-everyone-teachers-could-lose-their-licenses-while-students-could-be-transferred-out-of-school\/\" target=\"_blank\" rel=\"noopener\">NEW BLOW TO EDUCATION: Government preparing a law that will punish everyone \u2013 teachers could lose their licenses, while students could be transferred out of school!<\/a><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><a href=\"https:\/\/serbiantimes.info\/en\/the-medal-serbia-had-been-waiting-seven-years-for-marko-finishes-second-at-the-world-rowing-championships-silver-shining-like-gold\/\" target=\"_blank\" rel=\"noopener\">THE MEDAL SERBIA HAD BEEN WAITING SEVEN YEARS FOR: Marko finishes second at the World Rowing Championships, silver shining like gold!<\/a><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><a href=\"https:\/\/serbiantimes.info\/en\/human-and-sporting-greatness-dokovic-sends-powerful-words-to-one-of-his-greatest-rivals-on-his-induction-into-the-hall-of-fame-video\/\" target=\"_blank\" rel=\"noopener\">HUMAN AND SPORTING GREATNESS: \u0110okovi\u0107 sends powerful words to one of his greatest rivals on his induction into the Hall of Fame!
