As expected, muscle strength and the percentage body fat were correlated with the speed with which a lifeguard brought a victim to shore. Flexibility was correlated with the speed with which a female lifeguard brought a victim to shore, but it was inversely correlated with the speed with which a male lifeguard brought a victim to shore. An analysis was performed to determine how sex differences in physical characteristics contributed to the speed with which a lifeguard brought a victim to shore. Results indicated that males have significantly greater grip strength while females have a significantly greater percentage body fat. Flexibility did not differ significantly between males and females. Grip strength and flexibility were inversely correlated for both males and females., application/pdf}, pages = {7--10}, title = {ライフセーバーの性差による身体的特性の違い}, volume = {18}, year = {2018}, yomi = {カミナカ, トシアキ and タニカワ, マリナ and ヨコイ, オサム and サギサカ, リョウ and サクライ, マサル and ハタ, カツヒコ} }
