Roller derby is a fast sport.
Two teams race on a track. They wear four-wheeled skates. Skaters also wear pads to stay safe.
Each team has five skaters on the track. One skater is the jammer. The jammer wears a star on her helmet. She scores points by passing other skaters.
The other four skaters are blockers. Blockers try to stop the other team. They also help their own jammer pass through. They can skate in a line called a wall.
Sometimes a skater breaks a rule. That skater must sit in a penalty box. This makes it harder for her team to score. It is a very exciting game to watch.
Roller derby is a fast contact sport.
Two teams race on an oval track. Each team has up to 15 players. Only five skaters play at one time. One skater is the jammer. She wears a star on her helmet.
The jammer scores points by lapping blockers. The other four skaters are blockers. They form a pack to move together. Blockers can make a wall to stop the other jammer.
One blocker is the pivot. She wears a stripe on her helmet. She can become the jammer if she gets the star.
Skaters use quad skates with four wheels. They must wear helmets and pads to stay safe.
If a skater breaks a rule, she goes to a penalty box. This is called a penalty. Her team must play with fewer people. This can lead to a power jam. In a power jam, one team has more skaters to help them score.
Roller derby is a fast and exciting contact sport.
It is played by two teams on an oval track. Most teams are made of amateur players. There are about 1,250 leagues around the world. The United States is where the sport is most popular.
People love it for its unique style. Many leagues use a "do-it-yourself" spirit. They mix athletic skill with punk and camp styles. This makes the sport feel very special to the skaters.
A game is called a bout. It lasts 60 minutes in total. The bout is split into many short segments called jams. Each jam lasts for two minutes.
During a jam, five skaters from each team are on the track. One player is the jammer, who wears a star on her helmet. The other four players are blockers. One blocker might also be the pivot, who wears a stripe. The jammer scores points by lapping the opposing blockers.
To score, the jammer must be upright and in-bounds.
Roller derby has a long and interesting history. It started in the 1930s with marathon skating on banked tracks.
Leo Seltzer and Damon Runyon helped turn it into a competitive sport. In 1940, over 5 million people watched it in American cities. For a long time, it was mostly theatrical entertainment. However, the sport had a grassroots revival in the early 2000s. Now, it is a real sport without scripted winners.
There are many specific rules to follow.
Blockers use their bodies to help their jammer or stop the other team. They can form a "wall" by skating side by side. They cannot use hands, elbows, or feet to block. If a player breaks a rule, they go to a penalty box.
They must stay there for 30 seconds of jam time. This can create a "power jam." In a power jam, one team has more skaters to help them score.
Safety is a very important part of the game.
Every skater wears quad skates with four wheels. They must also wear helmets, wrist guards, elbow pads, and knee pads. Many players also wear mouth guards. Some teams even wear extra gear like padded pants or hard-case sports bras. This gear helps protect them while they play. Roller derby is now an international sport with many different rulesets.
The WFTDA is a major group that sets rules for many leagues.
Roller derby is a fast-paced contact sport played on an oval track.
It involves two teams competing in a series of short, intense segments. These segments are called jams. A full game, or bout, typically lasts 60 minutes. This time is divided into two 30-minute periods. Most modern roller derby is played by amateur athletes. There are approximately 1,250 amateur leagues worldwide. While it is very popular in the United States, it is an international sport.
Each team usually has a roster of about 15 skaters. During a jam, five skaters from each team are on the track. One player is the jammer, identified by a star on their helmet.
The other four players are blockers. One blocker may also serve as the pivot, marked by a stripe on their helmet. The jammer is the only player who scores points. They score by lapping opposing blockers while skating counterclockwise. To earn a point, the jammer must be upright and in-bounds. If a jammer passes the entire pack, it is a four-point trip called a "grand slam."
Blockers play both offense and defense at the same time. They use their bodies to hinder the opposing jammer. They also maneuver to help their own jammer pass through the pack. Blockers can form a "wall" by skating side by side. This formation makes it difficult for the opponent to move through. However, blockers cannot link arms or grasp each other to stay connected. They must also avoid using hands, elbows, heads, or feet to block. Contact is also prohibited above the shoulders or below the mid-thigh.
Strategy is a vital part of the game's complexity. The lead jammer is the first person to break through the pack. This player earns "lead jammer" status. This allows them to stop the jam at any time by placing their hands on their hips. This is a key tactic to prevent the other team from scoring. Another strategy is the "star pass." This occurs when a jammer hands their star helmet cover to the pivot. The pivot then becomes the new jammer. This can happen because of fatigue or a better scoring position.
Rules are strictly enforced by referees to ensure fair play. If a skater commits a foul, they are sent to a penalty box. They must stay there for 30 seconds of jam time. While a player is penalized, their team must play short-handed. This can lead to a "power jam." In a power jam, one team has a numerical advantage. This advantage can have a major effect on the final score. If a player receives seven penalties, they "foul out" and must leave the game.
Roller derby has a unique history that has changed over time. It began in the 1930s with banked-track roller-skating marathons.
Leo Seltzer and Damon Runyon helped evolve it into a competitive sport. In 1940, more than 5 million spectators watched the sport in American cities. For many decades, it became a form of sports entertainment with scripted winners. However, a grassroots revival in the early 2000s changed this. Modern derby has abandoned scripted results in favor of real athleticism. It now maintains a "do-it-yourself" ethic mixed with punk and camp styles.
Safety is managed through specific equipment requirements.
All players use quad skates, which have four wheels. They must wear helmets, wrist guards, elbow pads, and knee pads. Mouth guards are also common. Some leagues require extra gear like padded pants or hard-case sports bras. The sport is governed by various organizations. The Women's Flat Track Derby Association (WFTDA) is a major governing body. In 2010, over 98% of competitions used WFTDA rules. The sport is so widely recognized that it was considered for the 2020 Summer Olympics.
