Age-related blunting of serial sarcomerogenesis and mechanical adaptations following 2 weeks of maximal eccentric resistance training

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

Effects of intensified training with insufficient recovery on joint level and single muscle fibre mechanical function: The role of myofibrillar Ca2+ sensitivity

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.

The Effect of Gradual Ovarian Failure on Dynamic Muscle Function and the Role of High Intensity Interval Training on Mitigating Impairments

This study investigates how gradual ovarian failure affects skeletal muscle function in mice and finds that high intensity interval training partially mitigates power loss in fast-type muscle fibers.

Ultrasonographic measurements of fascicle length overestimate adaptations in serial sarcomere number

This study shows that ultrasound-derived fascicle length measurements overestimate increases in serial sarcomere number by ~5% in rat plantar flexor muscles following chronic stretch.

Effects of VCD-induced ovarian failure on single muscle fiber contractility in a mouse model of menopause

This study examines how gradual ovarian failure in a mouse menopause model affects single muscle fiber contractility, finding no significant differences in force per CSA but altered calcium sensitivity in specific muscles.

An increase in serial sarcomere number induced via weighted downhill running improves work loop performance in the rat soleus

Age-related reductions in the number of serial sarcomeres contribute to shorter fascicle lengths but not elevated passive tension

This study examines age-related changes in muscle architecture, finding shorter fascicle lengths and reduced serial sarcomere numbers in older rats, but no elevation in passive tension.

The influence of training-induced sarcomerogenesis on the history dependence of force

This study examines how training-induced changes in sarcomere number affect residual force enhancement and depression in rat muscles, finding no significant impact on force magnitude.
