The performance-enhancing altitude mask that Olympic hopeful Sivert Guttorm Bakken was wearing when he was found dead this week “is not part of the Norwegian Biathlon Association’s organized training programs,” the federation said Friday.
Bakken, 27, was found dead in his hotel room in the Alpine town of Lavaze in the Trentino region of Italy on Tuesday.
He was located at high altitude, with the Lavaze Pass measuring 1,808 meters (nearly 6,000 feet) in elevation.
The fact Bakken was wearing a device aimed at simulating high-altitude conditions, which can potentially improve endurance, has raised concerns — especially since Bakken was diagnosed with myocarditis, a heart condition, in 2022 and sat out two seasons.
“The use of such equipment is not part of the Norwegian Biathlon Association’s organized training programs. However, we are aware that a few individual athletes have acquired such equipment. Any use must be in line with the guidelines of the Olympic Council. Such use is not in conflict with the Norwegian sports regulations,” the federation said in a statement, adding that it banned the use of such masks immediately after Bakken’s death “until further notice.”
Bakken was the reigning European champion in the 10-kilometer sprint and two relays and was preparing to compete in the 2026 Milan Cortina Winter Olympics. He had one individual World Cup victory and three in relays.
He competed as recently as last Sunday in Annecy, France, finishing 20th in a 15-kilometer mass start event. A day earlier, he finished 18th in a 12.5-kilometer pursuit.
“There are currently many rumors and unconfirmed information related to Bakken’s death. Only when we have received a report from the police and forensic authorities in Italy will we be able to comment on what probably happened and the probable cause of death. This will probably not happen until next week,” said Bernt Heiberg, a lawyer employed by the federation.
“We emphasize that although it has been reported that the deceased was wearing an altitude mask when he was found, there is currently no confirmed information about what role this may have played in the death,” Heiberg added, “We would again urge caution in discussing details related to the death that have not been confirmed by the Italian police at this time.”
An autopsy on Bakken was due to be performed in Italy before his body can be brought home for a funeral.
Norway is the dominant force in biathlon. Its athletes won six golds and 14 medals in the sport at the last Winter Olympics in Beijing nearly four years ago — twice as many second-ranked France in both categories.

DUBAI, United Arab Emirates (AP) — Iran fired more missiles at Israel and Gulf Arab states Thursday, demonstrating Tehran’s continued ability to strike its neighbors even as U.S. President Donald Trump claimed the threat from the country was nearly eliminated.
Iran’s attacks on Gulf states along with its chokehold on the Strait of Hormuz have disrupted the world’s energy supplies with effects far beyond the Middle East. That has proved to be Iran’s greatest strategic advantage in the war. Britain held a call with nearly three dozen countries about how to reopen the strait once the fighting is over.
Trump has insisted the strait can be taken by force — but said it is not up to the U.S. to do that. In an address to the American people Wednesday night, he encouraged countries that depend on oil from Hormuz to “build some delayed courage” and go “take it.”
Before the U.S. and Israel started the war on Feb. 28 with strikes on Iran, the waterway was open to traffic and 20% of all traded oil passed through it.
Iran responded defiantly to Trump’s speech, in which the American president claimed U.S. military action had been so decisive that “one of the most powerful countries” is “really no longer a threat.”
A spokesman for Iran’s military, Lt. Col. Ebrahim Zolfaghari, insisted Thursday that Tehran maintains hidden stockpiles of arms, munitions and production facilities. He said facilities targeted so far by U.S. strikes are “insignificant.”
Just before Trump began his address — in which he said U.S. “core strategic objectives are nearing completion” — explosions were heard in Dubai as air defenses worked to intercept an Iranian missile barrage.
Less than a half-hour after the president was done, Israel said its military was also working to intercept incoming missiles. Sirens sounded in Bahrain, home to the U.S. Navy’s 5th Fleet, immediately after the speech.
Attacks continued across Iran on Thursday, with strikes reported in multiple cities.
Iran state media reported that strikes on the B1 bridge, which was still under construction, killed eight people and wounded 95. The outlet, citing authorities in Alborz province, said the victims had gathered under the bridge and along the riverbank for Nature Day, which Iranians celebrate by gathering outside.
In a post on X that included a picture of what appeared to be the same bridge, Iran’s Foreign Minister Abbas Araghchi wrote, “Striking civilian infrastructure only conveys the defeat and moral collapse of an enemy in disarray.”
Trump posted footage on social media showing what he said was the collapse of Iran's biggest bridge and threatening, “Much more to follow.” It was not immediately clear if the footage Trump shared was the B1 bridge, reportedly the tallest in the Middle East.
In Lebanon — where Israel has launched a ground invasion against Iran-backed Hezbollah militants — Israeli strikes have killed 27 people in the past 24 hours, the Health Ministry said.
More than 1,900 people have been killed in Iran during the war, while 19 have been reported dead in Israel. More than two dozen people have died in Gulf states and the occupied West Bank, while 13 U.S. service members have been killed.
More than 1,300 people have been killed and more than 1 million displaced in Lebanon. Ten Israeli soldiers have also died there.
Iranian attacks on about two dozen commercial ships, and the threat of more, have halted nearly all traffic in the waterway that connects the Persian Gulf to the open ocean.
Since March 1, traffic through the strait has dropped 94% over the same period last year, according to the Lloyds List Intelligence shipping data firm. Two ships are confirmed to have paid a fee, the firm said, while others were allowed through based on agreements with their home governments.
Saudi Arabia piped about 1 billion barrels of oil away from the Strait of Hormuz in March, according to maritime data firm Kpler, while Iraq said Thursday that it had started to truck oil across Syria to avoid the strait.
The 35 countries that spoke Thursday, including all G7 industrialized democracies except the U.S., as well as the United Arab Emirates and Bahrain, signed a declaration last month demanding Iran stop blocking the strait.
Thursday’s talks were focused on political and diplomatic measures, but British Foreign Secretary Yvette Cooper said military planners from an unspecified number of countries will also plot ways to ensure security once fighting ends, including potential mine-clearing work and “reassurance” for commercial shipping.
No country appears willing to try to open the strait by force while the war is raging. French President Emmanuel Macron, while on a visit to South Korea, called a military operation to secure the waterway “unrealistic.”
But there is a concern that Iran might limit traffic through the waterway even after U.S. and Israeli attacks cease.
The conflict is driving up prices for oil and natural gas, roiling stock markets, pushing up the cost of gasoline and threatening to make a range of goods, including food, more expensive.
Oil prices remained elevated, however, at $111.54 for a barrel of U.S. crude, having soared following Trump’s address. That's up about 50% from Feb. 28.
Though the oil and gas that typically transits the strait is primarily sold to Asian nations, Japan and South Korea were the only two countries from the region joining Thursday's call about the strait. The supply of jet fuel has also been interrupted, with consequences for travel worldwide.
