Yelena Isinbayeva, the 2012 Olympic pole-vault champion, was among the 68 athletes to appeal and may now be unable to defend her title in Rio
Russian olympic style sports competitors will stay banned from the Olympics taking after cases the nation ran a state-supported doping program.
The Russian Olympic Committee (ROC) and 68 Russian competitors endeavored to topple the suspension, actualized by the body that represents world games.
However, the Court of Arbitration for Sport (Cas) has ruled it can stand.
A handful of Russian athletes could still compete as neutrals at the Rio Games, which start on 5 August.
"It's pitiful yet guidelines are tenets," said Olympic 100m and 200m champion Usain Bolt, who will pursue more gold awards in Rio.
He said it was imperative to send a solid message to the dopers.
"Doping infringement in olympic style events is getting truly awful," said the Jamaican, 29. "In the event that you cheat or go or against the principles, this will frighten many individuals."
In any case, Russian shaft vaulter Yelena Isinbayeva - one of the 68 to speak to Cas - said the decision was "an outright political request".
The 2012 gold medallist, 34, told the Tass news organization: "Thank all of you for this memorial service for games."
The International Association of Athletics Federations (IAAF) said it was "satisfied Cas has bolstered its position", including that the judgment had "made a level playing field for competitors".
IAAF president Lord Coe included: "This is not a day for triumphant proclamations. I didn't come into this game to prevent competitors from contending.
"Past Rio, the IAAF taskforce will keep on working with Russia to set up a spotless safe environment for its competitors so that its alliance and group can come back to universal acknowledgment and rivalry."
Independently, the International Olympic Committee (IOC) is thinking about calls to boycott every Russian contender over all games from the Rio Games taking after a second report into state-supported doping.
What now for Russia's competitors?
Some Russian competitors could contend in Rio as neutrals in the event that they meet various criteria, including being over and over tried outside their country.
No less than two - 800m runner and doping informant Yuliya Stepanova and US-based long jumper Darya Klishina - have gone down that way.
Presently the Cas administering has made room for additional to take after.
Cas said the ROC could in any case select competitors to contend as neutrals. In any case, a Cas representative said the adjudicatory board had communicated worries that this exited "no probability" for competitors to consent to the criteria.
Why were Russian competitors banned?
Russia was suspended from olympic style sports occasions by the IAAF in November 2015 after the distribution of a free World Anti-Doping Agency (Wada) report that demonstrated a society of across the board, state-supported doping.
Sports serve Vitaly Mutko apologized for Russia's inability to get the tricks yet held back before conceding the outrage had been state-supported.
In any case, another Wada-dispatched report conveyed not long ago - the McLaren report - contained all the more harming assertions and proposed senior figures in Russia's games service were complicit in a sorted out concealment.
The report embroiled the greater part of Olympic games in the concealment and guaranteed that Russian mystery administration specialists were included in swapping positive pee tests for clean ones.
Taking after Monday's distribution of the McLaren report, the IOC confronted calls to restriction every Russian contender from the 2016 Olympics and will hold a second crisis meeting on Sunday to choose its strategy.
How has Russia reacted?
The Russian powers have as of now proposed that they will take a gander at approaches to proceed lawful activity.
Taking after the decision, sports priest Mutko said Cas had set "a specific point of reference" by rebuffing an aggregate gathering for doping offenses by people.
Kremlin representative Dmitry Peskov included: "The standard of aggregate obligation can't be worthy. The news is bad."
Shouldn't something be said about other response?
Louise Hazel, a previous Olympic heptathlete from Britain:
"It's a miserable business but at the same time it's a stage in the right bearing. I laud everyone included for taking a hard line. I'm truly satisfied to see they have taken a truly solid position and that the boycott has been maintained."
