Isometric and Ballistic Performance in Canoeing and Weightlifting

open access: yesGazi Beden Eğitimi ve Spor Bilimleri Dergisi, 2023
Weightlifters produce strength and power in the vertical plane, while canoeists produce strength and power in the horizontal plane. The purpose of the study is to examine the difference between isometric strength and ballistic force of athletes in weightlifting and canoeing, at which strength and power production occurs in different planes. 84 athletes
