Microdosed Versus Conventional Plyometric Training in Adolescent Basketball Players
Sponsor: Chongqing Normal University
Summary
This randomized controlled trial compared microdosed and conventional plyometric training in adolescent male basketball players. Forty participants aged 12-16 years were randomly assigned to either a microdosed training group or a conventional training group for 8 weeks. Both groups performed the same plyometric exercises and completed the same weekly training volume of 240 ground contacts. The microdosed group completed six sessions per week with 40 ground contacts per session, whereas the conventional group completed two sessions per week with 120 ground contacts per session. The study evaluated changes in jump performance, reactive strength, sprint performance, agility, and body composition. The study was completed before registration on ClinicalTrials.gov and is being registered retrospectively for transparency.

Microdosed Plyometric Training
The intervention lasted 8 weeks. Participants completed six sessions per week with 40 ground contacts per session. Each session included ankle hops (2 sets × 10 repetitions), hurdle jumps over 70-cm hurdles (3 sets × 5 repetitions), and drop jumps from a 50-cm box (5 repetitions). Participants rested for 30 seconds between sets of ankle hops and hurdle jumps and 15 seconds between drop-jump repetitions. The total weekly volume was 240 ground contacts.
Conventional Plyometric Training
The intervention lasted 8 weeks. Participants completed two sessions per week with 120 ground contacts per session. Each session included ankle hops (6 sets × 10 repetitions), hurdle jumps over 70-cm hurdles (9 sets × 5 repetitions), and drop jumps from a 50-cm box (15 repetitions). Participants rested for 30 seconds between sets of ankle hops and hurdle jumps and 15 seconds between drop-jump repetitions. The total weekly volume was 240 ground contacts.
