Loikkasarjat

Loikkasarjat, literally "jump sequences" in Finnish, refer to a family of training drills in which athletes perform a series of successive jumps or bounds with brief recovery intervals between efforts. The aim is to develop explosive leg power, reactive strength, and neuromuscular coordination, which contribute to sprint speed, vertical leap, and jumping distance. The concept is used widely in track and field conditioning, volleyball, basketball, and rehabilitative contexts where plyometric training is appropriate.

Typical formats vary, but common features include multiple repetitions of jumps in a single set, controlled technique, and short rest periods. Drills may emphasize vertical jumps, horizontal bounds, or bounds with progressive distances. Coaches adjust the number of repetitions, sets, height or distance targets, and rest to match the athlete's level and goals. Safe practice emphasizes proper warm-up, landing mechanics, soft surfaces, and gradual load progression to reduce injury risk.

Origin and usage: The term is Finnish, derived from loikka (jump) and sarja (series). While loikkasarjat are described in Finnish sports science and coaching literature, there is no single universal standard protocol; practices vary by sport and trainer.

Related concepts include plyometric training and bounding drills, which share the core principle of producing maximal force in minimal time through rapid stretch-shortening cycles.
