Those are an invention of the anime, and almost certainly a deliberate invocation of this trope. He also has a lot more " ATATATATATATA! " moments in the anime than the manga. He also looks a lot more like Lee in the original anime. Might Gai and Rock Lee (who shares Bruce Lee's birthday) of Naruto come complete with bowl-cuts and ugly jumpsuits. Spike from Cowboy Bebop has a love for the 20th century icon, and bases his style on Jeet Kune Do. He states that he is a follower of Bruce's brand of philosophy.
One-inch punches, bowl-cuts, yellow jumpsuits and nunchaku are also common, despite Lee himself devoting his life to stripping away such extravagances, mysticism, and inefficient techniques in martial arts. Members of this trope may have honed their bodies to superhuman levels through relentless training, Charles Atlas style.
