Eccentric plantar flexor contractions
Eccentric plantar flexor contractions has been studied in 1 paper since 2026: 1 trial in people; 1 in the past year. The newest paper, Oct 17, 2026: “Effects of muscle length and age on neuromuscular responses to maximal eccentric contractions of the plantar flexors”.

“Voluntary activation decreased only at long lengths, with no age difference.”

Eccentric plantar flexor contractions decrease maximal voluntary isometric contraction in humans (Long: -33.6 ± 13.2%; short: -8.4 ± 15.7%).
“with a greater (p = 0.021) MVIC decrease at long (-33.6 ± 13.2%) than short lengths (-8.4 ± 15.7%).”
