A: age of subject (years); BH: box height for plyometric drop jumps (cm); BM: body mass (kg); CMJ: countermovement jump; CMJA: countermovement jump with arms; Comb: combined; F: female; Freq: frequency of training (days/week); H: height of participants (cm); Int: intensity of training. For maximal, this involved either maximal effort to achieve maximal height, distance, reactive strength index, velocity, or another marker of intensity; IS: in-season; M: male; MOD: Moderate; N: number of participants; PJT: plyometric jump training; PO: progressive overload, in the form of either volume (i.e., V), intensity (i.e., I), type of drill (i.e., T), or a combination of these; PS: pre-season; R: replacement of habitual training drills with plyometric jump training drills; RBR: rest between repetitions; RBSE: rest between sets and/or exercises; RBTS: rest between training sessions; RBVJ: repeated bilateral vertical jumps; RT: resistance training; SPT: systematic plyometric jump training experience; SSC: stretch-shortening cycle; Surf: surface type; T: tapering; TJ: total plyometric jumps; TP: training period of the season; Type: type of PJT drill. When “Mix” is indicated, this involved a combination of 2 or more of the following jumping drills: vertical, horizontal, bilateral, unilateral, repeated, non-repeated, lateral, cyclic, sport-specific, slow stretch-shortening cycle, fast stretch-shortening cycle; Wk: weeks of training.

*Fitness level: high, for professional/elite athletes with regular enrollment in national and/or international competitions, highly trained participants with >10 training hours per week or >6 training sessions per week and a regularly scheduled official and friendly competitions. Moderate, for non-elite/professional athletes, with a regular attendance in regional and/or national competitions, between 5 and 9.9 training hours per week or 3–5 training sessions per week and a regularly scheduled official and friendly competitions. Normal, for recreational athletes with <5 training hours per week with sporadic competitions’ participation, and for physically active participants and school-age youths regularly involved in physical education classes.
