Swingthroughs are simply singular transitions where the in-air leg continues on a linear path past the base leg, creating or maintaining momentum to initiate the next trick. For many mainstream terminology users, this transition is often synonymous with a backswing; a swing of the leg from back to front that is used to initiate a back flipping axis. Increasingly, the swingthrough is understood to be any directional swing of the leg where momentum is not broken or greatly altered, creating at least 4 separate swingthrough possibilities, one for each flipping axis: forward, backward, inside-side, and outside-side. This understanding is spreading rapidly through the tricking community as a whole, and is becoming increasingly common among mainstream trickers.
The 2016 update of Aeriformmat has reclassified this type of transition as a “Complex” transition, and is one of 2 complex transitions, along with the Missleg transition.
- Obviously the most common swingthrough is to the gainer and cork axis, but this trend is increasingly diversifying with the popularization of other tricks, such as the GMS.
