Standing triple jump Standing triple jump Standing triple jump is an athletics event based on the conventional triple jump with three jumping phases, but without an approach run-up. It is one of three standing variants of track and field jumping events, along with the standing high jump and standing long jump. While it is no longer an official competitive event, it is still used as a training exercise. The first phase is a hop from a stand still, which requires the athlete to take-off from a two-footed stand, split in mid air, and land on the preferred foot. The next phase is a
Hop (protein) Hop (protein) Hop, occasionally written HOP, is an abbreviation for Hsp70-Hsp90 Organizing Protein. It functions as a co-chaperone which reversibly links together the protein chaperones Hsp70 and Hsp90. Hop belongs to the large group of co-chaperones, which regulate and assist the major chaperones (mainly heat shock proteins). It is one of the best studied co-chaperones of the Hsp70/Hsp90-complex. It was first discovered in yeast and homologues were identified in human, mouse, rat, insects, plants, parasites, and virus. The family of these proteins is referred to as STI1 (stress inducible protein) and can be divided into yeast, plant, and animal STI1
