Training protocol with three sets of “correct” and “incorrect” repetitions, each. While the break conditions change between sets ($2 \mathrm{s}$, $1 \mathrm{s}$, or $0 \mathrm{s}$), the repetition duration remains equal ($4 \mathrm{s}$). The numbers in the boxes indicate the total number of repetitions collected from 15 subjects.
