A force profile is simply a curve that is measured as you take yourself through a movement and measure the amount of resistance at each point during that movement. For example, everybody knows what a biceps curl looks like. At the bottom of the movement you have no resistance, half way through the movement (at about 90 degrees) it becomes maximally difficult, and then once you get to the top of the movement it becomes slightly easier again.

In baseball statistics, on-base percentage (OBP) is a measure of how often a batter reaches base for any reason other than a fielding error, fielder's choice, dropped or uncaught third strike, fielder's obstruction, or catcher's interference. OBP is calculated in Major League Baseball (MLB) by dividing the sum of hits, walks, and times hit by a pitch by the sum of at-bats, walks, times hit by pitch and sacrifice flies.[1] A hitter with a .400 on-base percentage is considered to be great[2] and rare;[3] only 55 players in MLB history with at least 3,000 career plate appearances (PA) have maintained such an OBP. Left fielder Ted Williams, who played 19 seasons for the Boston Red Sox, has the highest career on-base percentage, .4817, in MLB history.[4] Williams led the American League (AL) in on-base percentage in twelve seasons, the most such seasons for any player in the major leagues.[4][5] Barry Bonds led the National League (NL) in ten seasons, a NL record.[5][6] Williams also posted the then-highest single-season on-base percentage of .5528 in 1941, a record that stood for 61 years until Bonds broke it with a .5817 OBP in 2002.[7] Bonds broke his own record in 2004, setting the current single-season mark of .6094.[7]

Prior to 2010 we only listed the top 100 and monitored those who made and slipped off the list. Here is that original fast fact preserved and now useless due to the list including 1000 names: Modern superstars are making the list as they meet the one-thousand minimum games played threshold: In 2001 Jeff Cirillo & Manny Ramirez met the requirements and joined the top one-hundred. In 2002 Cirillo slipped off the chart and Jason Giambi made it while Chipper Jones & Alex Rodriguez missed the cutoff by less than 2/1000 of a point. In 2003 Jason Giambi slipped off the chart, Chipper Jones just missed it once again (his career average is .30870), and Vladimir Guerrero vaulted onto the list at forty-first — higher than any other active player, that is until 2004 when Todd Helton launched into the top 20 all-time.
In modern times, a season batting average higher than .300 is considered to be excellent, and an average higher than .400 a nearly unachievable goal. The last player to do so, with enough plate appearances to qualify for the batting championship, was Ted Williams of the Boston Red Sox, who hit .406 in 1941, though the best modern players either threaten to or actually do achieve it occasionally, if only for brief periods of time. Ty Cobb holds the record for highest career batting average with .366, 9 points higher than Rogers Hornsby who has the second highest average in history at .358.
