A front flip in a long jump competition sounds impossible, but Tuariki Delamere used it to expose a flaw the sport had overlooked. After struggling against stronger American jumpers at Washington State and coming off a disappointing finish at the Commonwealth Games, the New Zealand athlete turned to a radical idea: the somersault long jump. With guidance from his biomechanics professor, he practiced the move in the pole vault pits, took a hard fall, and still decided to try it under pressure at the LA Pacific Championships.

Only Delamere and his coach knew what was coming when he sprinted down the runway at the LA Coliseum. His first attempt was a perfect front flip landing, but officials ruled it overstepped the mark. On the second jump he rotated smoothly again, landing at 8.4 metres before falling back to 7.7 metres, still matching the day’s winning mark and showing just how much distance the technique could unlock. The reaction was immediate: the idea had real biomechanical advantages, but it was soon banned as too dangerous.

This sports history documentary explores long jump innovation, biomechanics, track and field strategy, and the moment a single athlete changed the conversation around performance and technique. It’s a compelling watch for fans of athletics history, Olympic-era stories, and unusual sports breakthroughs.

For viewers searching for long jump history, track and field documentary, biomechanics in sports, somersault long jump, athletics innovation, and banned sports techniques, this story delivers a fascinating look at one of the most daring experiments ever seen in competition.

00:00Nobody had ever attempted a front flip in an official long jump competition, but this crazy Kiwi had discovered something
00:07that the professionals had overlooked.
00:09Tariki John Delamere was one of the best long jumpers in New Zealand.
00:13However, after accepting a scholarship at Washington State and arriving in the U.S., John fell a little bit out
00:18of his depth with the American professionals.
00:20They were all outperforming him, the 1974 LA Pacific Championships were coming up, and after finishing 9th in the Commonwealth
00:27Games in his own home country earlier that year, John felt like he'd let himself and his country down.
00:33John desperately needed to find another way to be competitive.
00:36It had been long rumoured that a front flip could possibly be the most optimal long jump technique from a
00:41biomechanics perspective, but had never been attempted in a competition.
00:45So John decided he was going to be the first to try it at the Pacific Championships in the LA
00:50Coliseum, and in doing so, he'd change the sport of long jump forever.
00:54The idea of a front flip in long jump had been talked about for years.
00:58Experts believed it could help jumpers go further by using the body's natural rotation to boost momentum.
01:04The flip would turn the jumper's upward motion into forward motion, potentially adding crucial inches to the jump.
01:10While the concept was exciting, no one had dared to try it in competition, due to the high risk of
01:15injury.
01:16With guidance from his biomechanics professor at Washington State, John saw this as his chance to break new ground and
01:22stand out in the sport.
01:24Whispers had begun to circulate that the Russians were planning to deploy the front flip long jump at the 1976
01:30Montreal Olympics.
01:32John wasn't just pioneering a new technique, he was potentially beating the world to a groundbreaking athletic innovation which would
01:39completely change the sport of long jump in the same way that the Fosbury flop had completely revolutionised the high
01:45jump just six years earlier.
01:47When John realised the potential for this unconventional and risky technique, he took to the pole vault pits to practice
01:53in a way that would hopefully reduce the risk of injuring himself.
01:56He practiced the flip for days, and it seemed at first like he just wasn't going to be able to
02:01do it.
02:01It's a dangerous move for someone untrained in gymnastics, and after landing on his tailbone particularly badly, he thought he'd
02:08irreparably damaged his spine, and he was ready to give up on this insane idea.
02:12However, the championships were coming up fast.
02:14John was running out of time to practice the move, and he wasn't willing to risk hurting himself again before
02:19the competition.
02:20He decided that the next time he would try the jump, he'd do it for real at the Pacific Championships.
02:25When the day finally arrived, only two people in the stadium knew what was about to happen.
02:30John and his coach.
02:32John prepared for his first jump.
02:34He sprinted down the runway, and he launched into the air.
02:36He executed the front flip perfectly, landing feet first, far ahead of all the previous jumpers.
02:42The officials stood there, stunned, with their mouths open.
02:45It impressed everyone.
02:46But once the officials processed what just happened, they informed John that he had unfortunately overstepped the mark, and the
02:52jump didn't count.
02:53Despite this, it was clear that the adrenaline was working, and John was onto something extraordinary.
02:58For his second jump, John was even more focused.
03:01The crowd swelled, and they watched with bated breath to see if he would attempt the flip again.
03:06The tension in the stadium was palpable.
03:09As John took off again, he leapt from behind the line, and his body rotated smoothly through the air.
03:14He landed feet first once again, this time with his heels touching down at the 8.4 metre mark.
03:20The longest jump in NCAA history.
03:23But in the final moments of the jump, his hands planted down behind him, causing him to fall back to
03:287.7 metres.
03:31John's jump was still enough to equal the day's winning jump from the reigning Olympic champion, Randy Williams.
03:36It was a bittersweet success, but John had done what he set out to do.
03:40He had successfully proved the enormous potential of the somersault long jump.
03:45John was only given one more opportunity to compete using the technique before the end of the season.
03:50By the time the next season rolled around, the International Association of Athletics Federations had banned the somersault long jump,
03:57deeming it too dangerous.
03:58As a result of the ban, John's jump remains the longest official somersault long jump in history.
04:06.
