This study tests if increasing relaxation strain during isometric exercise boosts sarcomerogenesis, finding greater SSN increases in burst contractions compared to sustained contractions.

This study examines how different contraction types during resistance training affect serial sarcomere addition in rats, finding that isometric and eccentric training drive sarcomerogenesis more than concentric training.

This study examines age-related changes in serial sarcomere number across five hindlimb muscles in rats at four aging timepoints, finding significant SSN loss contributing to muscle mass decline.

This study examines how chemically-induced ovarian failure affects muscle fibre contractility in mice, finding increased force and changes in fibre type proportions over time.

The study examines residual force enhancement and depression in old age, finding that force depression is amplified at the cellular level while force enhancement remains unchanged.

This study compares residual force enhancement (rFE) at the single fibre and joint levels in humans, finding greater rFE at the single fibre level and non-responder phenomena only at the joint level.

This study shows that intensified training with insufficient recovery reduces myofibrillar Ca2+ sensitivity in single muscle fibers, contributing to impaired neuromuscular function at lower activation frequencies.

This study compares age-related differences in serial sarcomere number recovery and muscle function after disuse in young and old rats, finding older rats recover longitudinal morphology better than parallel morphology.

This study shows that eccentric resistance training increases serial sarcomere number and improves mechanical function in young rats but causes impairments in older rats.

This study investigates how prior muscle lengthening or shortening affects perception of effort during isometric contractions, finding that effort perception varies with torque and EMG levels.
