what are the duties and responsibilities of IAAF?​

Answers

Answer 1

Answer:

World Athletics is the international governing body for the sport of athletics, covering track and field, cross country running, road running, racewalking, mountain running, and ultra running.

World Athletics is headed by a president. The World Athletics Council has a total of 26 elected members, comprising one president, four vice-presidents (one senior), the presidents of the six area associations, two members of the Athletes' Commission and 13 Council members. Each member of the Council is elected for a four-year period by the World Athletics Congress, a biennial gathering of athletics officials that consists of the Council, Honorary Members, and up to three delegates from each of the national member federations.[9] Chairpersons and member of Committees, which manage specialist portfolios, are also elected by the Congress. There are four committees: the Cross Country Committee, the Race Walking Committee, the Technical Committee, and the Women's Committee.[10] A further three committees were launched in 2019: Development, Governance and Competitions.[11] The governance structure is outlined in the World Athletics Constitution, which may be amended by the Congress.[12]

The World Athletics Council appoints a chief executive officer (CEO), who is focused on improving the coverage of the sport and the organisation's commercial interests. This role was created and merged with the General Secretary role that had existed previously. British former athlete and businessman Jon Ridgeon was appointed to the role in December 2018.[13] Olivier Gers was the first person to officially hold the position in 2016, succeeding the interim CEO/General Secretary Jean Gracia.[14]

In order to give active athletes a voice in the governance of the sport, World Athletics created the Athletes' Commission. Athletes are elected to the commission by other athletes, typically held at the Congress attached to the World Athletics Championships. The commission chairperson and one other athlete of the opposite sex are given voting rights on the Council. The last election was held in October 2019 at the 2019 World Athletics Championships.[15]

Following doping and corruption issues, a Code of Ethics was agreed in 2013 and an Ethics Commission was appointed in 2014.[16] The Council appoints the chairperson from the elected members, and in turn the chairperson appoints a deputy chair.[17] The Ethics Board's scope was limited in 2017 with the creation of the independent Athletics Integrity Unit, headed by Australia's Brett Clothier, to oversee ethical issues and complaints at arm's length.[18]

The International Athletics Foundation is a charity closely associated with World Athletics that engages in projects and programmes to develop the sport. Albert II, Prince of Monaco is the Honorary President and the role of IAF President is held by the World Athletics President.[19] A World Athletics Heritage department was created in 2018 to maintain historic artefacts and display them through a physical gallery in Monaco, a virtual online gallery, and a travelling exhibition. The department also issues World Athletics Heritage Plaques to commemorate locations of historic interest to the sport.[20]

Answer 2

Answer:

The International Association of Athletics Federations (IAAF) is the worldwide governing body for professional level athletics and track and field. Its purpose is to create and regulate professional level meets and to set the standards for administering competitions, using equipment, and documenting world records.

in what ways sleep influences the body's response to stress

Answers

Answer: each of us should be getting between 6-8 hours of rest every night, in order to remain fully awake and alert. Sleep is required for us to "reset" our programming. When we get the correct amount of sleep this makes us less likely to  become aggravated or aggitated by life's probelms because we are tired.

A lack of sleep can cause the body to react as if it's in distress, releasing more of the stress hormone, cortisol. Cortisol is responsible for your fight or flight reaction to danger, increasing your heart rate in anticipation of a fight.

Mark Brainliest please

There are a lot of weird sleep-related world records out there. From the longest line of human-mattress dominoes—2016 'dominoes' and took 14 minutes for all of them to fall—to the most people served breakfast in bed at once—418 people in 113 beds set up on the lawn of a Sheraton Hotel in China. But there's one record that remains elusive: who holds the record for longest consecutive slumber?



Tough to call

The length of time someone is actually asleep is pretty tough to measure, which is what has kept the official title out of the hands of sleepers around the world. That doesn't mean, however, that there have been no valiant attempts—though they don't really count as real sleep.

In October of 2017, Wyatt Shaw from Kentucky fell asleep for 11 days. He was just seven years old and doctors ran several tests with no conclusive explanations. Wyatt did wake up with cognitive impairment, particularly when walking and talking, but made a full recovery after treatment with drugs typically used in seizure management.

In 1959, UK hypnotist Peter Powers put himself under a hypnotic sleep for eight straight days. It made quite the splash in European media and radio shows, but doesn't quite count as sleeping.

Answers

Answer: im not sure but i think it would be c

Drug abuse can be characterized by all of the following except physical harm to yourself because of drug use. Therefore option C is correct.

"Physical harm to yourself because of drug use," is not an accurate characterization of drug abuse. While drug abuse can certainly lead to physical harm in the long term, it is not a defining characteristic.

The other options, A, B, and D, are commonly associated with drug abuse. Inability to focus on responsibilities, legal problems due to drug possession, and experiencing withdrawal symptoms when unable to access drugs are often seen as consequences or signs of drug abuse.

Therefore option C physical harm to yourself because of drug use is correct.
