Sumo wrestlers are incredibly strong athletes, especially known for their lower body strength, grip strength, and overall power, despite their large body mass which includes a substantial amount of body fat. They have impressive grip strength comparable to elite arm wrestlers, with some managing to max out grip dynamometers at around 85-100 kg. Their lower body strength is notable due to the intense physical demands of carrying their massive weight and the explosive power required in bouts. Their bone density and connective tissue strength are also superior to many other athletes, which helps withstand the tremendous forces in sumo wrestling matches. However, compared to some other athletes, sumo wrestlers may have surprisingly lower muscle strength in certain isolated tests and their physical fitness tests related to body movement can be lower. Their training is highly specialized in developing body power, stability, and explosiveness needed for the tachiai (initial charge) and match engagements. In sum, sumo wrestlers' strength is highly generalized and functions well for the sport's unique demands, combining mass, power, explosive movement, and grip, making them extremely strong, especially in terms of functional and combat strength in their sport context.
