Through expert consensus, these 10 technique flaws have been grouped into 5 modifiable risk factors: ligament dominance, quadriceps dominance, leg dominance or residual injury deficits, trunk dominance (“core” dysfunction), and technique perfection. Technique flaws are then summed up for an overall score. There are 10 technique flaws that are assessed as either having the apparent deficit or not during the TJA. The tuck jump assessment (TJA) was created as a “clinician friendly” tool to identify lower extremity landing technique flaws during a plyometric activity. J Strength Cond Res 31(3): 653–659, 2017-Due to the high rate of noncontact lower extremity injuries that occur in the collegiate setting, medical personnel are implementing screening mechanisms to identify those athletes that may be at risk for certain injuries before starting a sports season. Tuck Jump Assessment: An exploratory factor analysis in a college age population. “ hopscotch” by Dean McCoy is licensed CC BY 2.Lininger, MR, Smith, CA, Chimera, NJ, Hoog, P, and Warren, M. Now that you know all five jumps, what are your favorite jumps and leaps? Can you identify which type of jump they are? Assemblé might also also turn in the air and could be done in parallel rather than with the legs turned out. Like sissonne, assemblé can be small or huge. In dance class you’ll typically do this jump as an assemblé - the legs come together in the air. In choreography, dancers might land a one-to-two jump in an open position. The other half of a hopscotch is a jump from one foot to two. In fact, when students are struggling with sissonne, I’ll have them try the more familiar hopscotch to remind them what two-to-one feels like. In more contemporary dance forms this basic jump can be executed in all kinds of ways.Īn unusual example of sissonne-like jumping is half of what I call a hopscotch - jumping from second position plié to a single leg beneath you. Faille is another two-to-one ballet step. Typically we think of the larger, scissor-like sissonne which either land open (ouvert) or closed (fermé). Two to One - SissonneĪ simple sissonne in ballet is a small jump, usually from fifth position (two feet), that lands on one leg with the other in sur le cou-de-pied. They are often the hardest for beginning dance students to execute in combinations because of their unique transfer of weight. These final two jumps are a little less common in everyday movement. First part of Pas de basque (or the jazzier “Wizard of Oz” chassé).Though we might think primarily of grand jeté or saut de chat when we talk about leaps in dance class, there are many, many types of jumps that transition from one foot to the other. Smaller leaps could be described as a bound or an exaggerated run. Temps levé (sur le cou-de-pied or arabesque) or Step-hop.Some hops can be deceiving - the step may begin with a brush of one leg but when the take-off happens, that leg is already in the air, meaning the take-off is from a single foot.
Yes, to dance educators, there is a difference between a jump and a hop.
Mathematically, the human body (with two feet) is capable of only 5 basic jumps.
