Robert Cantu, professor of neurology and neurosurgery and co-founder of the CTE Center at Boston University School of Medicine, believes that children under the age of 14 should not play football.  Your brain is not fully developed and myelin (isolation of nerve cells) has a higher risk of shear when the brain is young. Myelination is completed at the age of about 15 years. Children also have a larger head relative to their height and a weaker neck.   A full list of changes to the football rules will be available on the NFHS website at www.nfhs.org. Click on « Activities & Sports » at the top of the homepage and select « Football ». Chronic traumatic encephalopathy (CTE) is caused by repeated brain trauma such as concussions and blows to the head that do not cause concussions. It was found in football players who had only played a few years, including some who only played at the high school level.   According to a 2017 study on the brains of deceased Gridiron football players, 99% of brains tested by NFL players, 88% of CFL players, 64% of semi-professional players, 91% of college football players and 21% of high school football players had various CTE stadiums.  Unlike college and the NFL, there is no mandatory steroid testing system in place at the high school level. (However, some schools test marijuana and other drugs.) This chart shows how the rules of high school football differ from the rules of the NFL. Since the 2019 high school season, Texas is the only state that does not base its football rules on the NFHS rule set and instead uses NCAA rules with some exceptions listed below.   During the 2018 season, Massachusetts also based its rules on those of the NCAA, but it adopted the NFHS rules in 2019.
 Most Canadian schools use Canadian football rules adapted to the game in high school. The exception is British Columbia, which uses NFHS rules as they are used in the United States.  Thirty-four states have a leniency rule that comes into play in unilateral matches after a prescribed point range has been exceeded at halftime or any other time thereafter. The nature of the leniency rule varies from state to state, with many using a « continuous clock » once the score margin is reached (the clock continues to work, except in certain situations, during games where the clock would normally stop). Other states end the game as soon as the margin is reached or exceeded. For example, Texas uses a 45-point grace rule (to stop the game) only in six-a-side football; For 11-a-side football, there is no automatic interruption, but coaches can mutually agree to use a continuous clock. French High School Football is an American football played by high school teams in the United States and Canada. It is one of the most popular interschool sports in both countries, but its popularity is declining.  According to the Washington Post, high school football participation declined by 9.1% between 2009 and 2019.
 « With this year`s rule changes, the committee has once again demonstrated that it is focused on minimizing risk in high school football, » said Bob Colgate, NFHS Director of Sports and Sports Medicine and liaison with the NFHS Football Rules Committee. « By expanding the parameters of a legal forward pass and redefining the chop block so that it can be more easily managed by game officials, the committee has taken steps to mitigate two potentially risky situations in the game. » Some principals believe that football is the most important extracurricular activity on campus. Each state in the United States has its own high school federation or federation that governs high school football and other sports. These associations oversee the awards of all states, name the stars of the district and compile the background. The NFHS Football Rules Committee consists of a representative of the NFHS member associations that apply the NFHS Football Rules, as well as a representative of the NFHS Coaches Association, the NFHS Officials Association and the NFHS Sports Medicine Advisory Committee. You`ll find more two-way players at the high school level because most high school teams don`t have enough quality players. A two-way player is one who plays both an offensive and a defensive position. Here are some examples of the different job combinations: An NFL-funded study reported that high school football players suffered 11.2 concussions per 10,000 games or exercises, nearly twice as many as college football players.  All changes were made by the Football Rules Committee of the National Federation of State Secondary School Associations (NFHS), which held its annual rules meeting in January. The NFHS Board of Directors then approved the committee`s seven proposals. Below the largest high school football stadiums by capacity.
Stadiums with a capacity of at least 10,000 people are included.    With their common ancestry, the nfHS rules of high school football are largely similar to the college game, although with some important differences: A change to the 2-3-8 rule dealt with the new definition of a chop block, now known as « a combined block of two or more teammates against an opponent other than the runner, with or without delay, with one of the blocks below the waist and one of the blocks above the waist ». Previously, the knee of the defensive player was used to determine the high and low components of a cutting block. The National Federation of State High School Associations (NFHS) sets the rules for high school football in the United States. The National Federation of State Secondary School Associations (NFHS) is revising its deliberate ground rules and « hash block » rules as two of the seven changes for the 2022 high school football season. At least one single high school rule has been adopted from college football. In 1996, the overtime rules originally used by Kansas high school teams beginning in 1971 were adopted by the NCAA, although the NCAA made five significant changes. During the 2018 season, every possession started from the 25-yard line. Since 2021, it has remained in force during the first two overtime procedures.
In the second overtime, teams must attempt a two-point conversion after a touchdown. Second, triple conversion attempts in overtime and then two-pointers are instead of possession from the 25-yard line, and successful attempts are counted as conversions instead of touchdowns. According to the latest nfhs high school athletics participation survey, 11-player football is the most popular high school sport for boys with 1,006,013 participants in 14,247 schools across the country. In addition, there were 31,221 boys who participated in 6-, 8- and 9-player football, as well as 2,604 girls in the four versions of the game for a total of 1,039,828. Other common injuries include injuries to the legs, arms and lower back.     « The question (with this rule) has always been: `If the defense makes a good game, do we save the offense by letting the quarterback throw the ball?` » said Richard McWhirter, chairman of the NFHS Football Rules Committee and deputy executive director of the Tennessee Secondary School Athletic Association. « This year, I think the committee felt that the well-being of passers-by and it was worth not subjecting the rule to additional blows. » Quarterbacks can direct the offense and ignite defense on security. Two minor amendments have been made to Rules 3-4-7 and 3-6-1a (1) e EXCEPTIONS, respectively. « This will strengthen the rule and also help the game`s officials, » McWhirter said. « I think they will be able to apply this rule better than in the past because it is difficult to determine `below the knee` and `above the knee`. I think it`s going to really improve the game. The Committee considered the EXCEPTIONS to paragraph 3-6-1(a)(1)(e) of the Regulations, which clarifies the requirements for a music box shortened by 25 seconds after a game interruption. This rule now includes an exception to the 3-5-7i rule, which states that a 40-second music box must be used after a foul committed solely by the defensive team.
The latest rule change for 2022 is an amendment to rule 1-3-3 regarding gaming equipment. Any match official – not just the referee – can tip the ball between the downs. Players will be able to wear the number 0 as the jersey number from 2022, as the range of acceptable numbers listed in the 1-4-3 rule has been expanded from 1-99 to 0-99. However, any number preceded by the number zero is illegal. In the 3-4-7 rule, any foul committed in the last two minutes of one of the two halves automatically leads to the offensive team`s option to start the game clock on the spot.
