Kroyter has been coached in the high jump since 2005 by Anatoly "Tolek" Shafran, at
Maccabi Tel Aviv. In 2009, he became Israel's first Youth (17 or younger) World Champion at the age of 16 by winning the gold medal with a high jump of 2.20 m at the
2009 World Youth Championships in Athletics (the sixth
IAAF World Youth Championships in Athletics) in
Brixen, Italy. That year Kroyter also won the Israeli senior championship in the high jump, with a jump of 2.19 m. He was hampered, however, by a thigh injury that prevented him from training. His jump of 2.24 at the age of 16 at a competition in Moscow in February 2010 remains as of August 2016 the
best high jump ever by a European youth under 17 years of age. In 2011, he cleared 2.28 m while he was 17 years of age (a personal best at the time). In 2014, he was about to retire because of pain from a relentless injury, but came back from it. Kroyter represented
Israel at the 2016 Olympics, at the age of 23. He exited in the
qualification round after having jumped 2.17 m. ==See also==
