Men's 400 metres world record progression
From wikipedia, the free encyclopedia.
The first world record in the 400 m for men ( athletics ) was recognized by the International Amateur Athletics Federation, now known as World Athletics , in 1912. The IAAF ratified Charles Reidpath's 48.2 performance set at that year's Stockholm Olympics as a world record, but it also recognized the superior mark over 440 yards (402.34 metres) run by Maxie Long in 1900 as a world record.
Through 2021, World Athletics has ratified 24 world records in the event. 
The following tables show the world record progression in the men's 400 metres, as ratified by World Athletics.

Sport Ariarne Titmus rival Summer McIntosh hands US legend Katie Ledecky first home 400m freestyle defeat in 11 years
For the first time in 11 years, Katie Ledecky has lost a 400 metres freestyle race in an American pool.
- Katie Ledecky had not lost a 400 metres freestyle race in the USA since 2012
- Summer McIntosh finished fourth at the 2023 World Championships behind Ledecky and Ariarne Titmus
- Titmus is the current world record holder in the event
Canadian teenager Summer McIntosh took the title at the US Open championships in Greensboro, North Carolina, beating 26-year-old Ledecky by nearly three seconds.
McIntosh, who swims for the Sarasota Sharks club in Florida, took the title in a meet record of 3 minutes 59.42 seconds, while Ledecky, a seven-time Olympic champion, touched next in 4:02.38.
Ledecky's last loss in the 400 free in her home country was at the 2012 US Olympic trials, when she placed third at age 15.
Last March, the 17-year-old McIntosh also snapped Ledecky's nine-year US win streak in the 200 free.
The significance of McIntosh's latest victory is difficult to gauge, since swimmers are at different stages of their training cycles as they ramp up preparations for the Paris Olympics in eight months' time.
McIntosh held the 400 free world record for three months before it was reclaimed by Australia's Ariarne Titmus with a winning time of 3 minutes 55.38 seconds at this summer's world championships in Fukuoka, Japan .
Ledecky was runner-up at worlds — swimming in a time of 3 minutes 58.73 seconds — while McIntosh struggled to a fourth-place finish, with New Zealand's own teenage star Erika Fairweather pipping her Canadian rival to claim bronze.
McIntosh's comeback victory after the disappointment of Fukuoka helps set up another tantalising battle in Paris between three of the sport's biggest stars.
Their battle in the 400 metres free at the World Championships was billed as the race of the century , but was ultimately a disappointment for McIntosh.
However, the then-16-year-old McIntosh still had a successful championships, winning the 200 metres butterfly and 400 metres individual medley, and seems set to star in the pool in Paris.
Both Titmus and McIntosh will skip the Doha World Championships , set to take place in February, to focus on the Paris Olympics starting in late July.
Titmus, as well as holding the world record, is also the reigning Olympic champion in the 400 free, with Ledecky taking gold in the event at the 2016 Rio de Janeiro Games.

McIntosh topples Ledecky in US Open 400m free
Posted: December 1, 2023 | Last updated: December 1, 2023
Canadian teen Summer McIntosh clocked a meet-record 3min 59.42sec to win the 400m freestyle at the US Open ahead of American distance great Katie Ledecky.
McIntosh, a four-time world champion, handed Ledecky her first defeat in the event in a US pool in 11 years, seven-time Olympic gold medallist Ledecky taking second in 4:02.38.
McIntosh held the 400m free world record for three months last year. But at the World Championships in Fukuoka, Japan, she finished a disappointing fourth as Australian Ariana Titmus regained the world record in winning gold ahead of Ledecky.
"After that race, I learned a lot about how to get back out after it," said McIntosh, who would go on to win 200m butterfly and 400m individual medley gold at Fukuoka.
"I had so many races after that that I was really happy with. No matter how bad one race is, you really get back up and get back into it."
McIntosh said she was "pretty happy" with the result in her first long-course race of a season pointed at the Paris Olympics.
"I was just really excited going into it and really didn't know what to expect ... I'll just kind of learn through this, learn from this, and kind of start to move forward for the rest of the year."
Ledecky, who hadn't lost a 400m free race in home waters since she was third at the 2012 Olympic trials as a 15-year-old, was coming off a victory in the 800m free on Wednesday.
She, too, is gearing up for Paris, with the US Olympic trials to be held in Indianapolis June 15-23.
The two finished comfortably ahead of third-placed Siobhan Haughey of Hong Kong, who clocked 4:06.32.
Kate Douglass pulled off an impressive double with victories in the women's 200m individual medley and the 50m free.
The reigning 200m medley world champion used strong breaststroke and freestyle legs to seize control of a race led by Torri Huske after the butterfly before Regan Smith gained the lead on the backstroke.
Douglass finished in 2:08.46 to finish ahead of Alex Walsh, whose 2:08.96 gave her silver ahead of Huske (2:09.10).
Less than half an hour later, Douglass returned to win the 50m free in 24.38sec, with Abbey Weitzeil and Huske tied for second in 24.41.
"I'm kind of shocked to win that one. I was pretty focused on the IM today," Douglass said.
American Michael Andrew won the men's 50m free in 21.80sec. Josh Liendo was second in 21.90 and Aruba's Mikel Schreuders was third in 21.93.
Seven-time Olympic gold medallist Caeleb Dressel, continuing his return to the sport after a lengthy break, won the "B" final in 21.99sec.
Chase Kalisz, fresh off altitude training in Colorado, won the men's 200m medley in 1:57.43 with Hungary's Hubert Kos second in 1:57.88 and Trenton Julian third in 1:58.46.
