Fatigue is the decrease in active force that happens after repeated muscle stimulation, and
post tetanic twitch potentiation (PTP) is the increase in twitch force observed after repeated …

The purpose of this study was to examine the effect of post‐tetanic potentiation on low
frequency fatigue in adult human quadriceps muscle. Sixteen subjects (10 male and six …

Relative force depression associated with muscle fatigue is reported to be greater when
assessed at short vs. long muscle lengths. This appears to be due to a rightward shift in the …

Understanding muscle fatigue properties at different muscle lengths is essential to improve
electrical stimulation applications in which impaired muscle is activated to produce function …

Twitch postactivation potentiation (PAP) in skeletal muscle is a well recognized and
accepted phenomenon. However, the mechanisms responsible for potentiation are not …

Low-frequency fatigue (LFF) and post-tetanic potentiation (PTP) were quantified at different
muscle lengths in rat medial gastrocnemius (GM) muscle. In situ experiments were …

Healthy untrained men performed 10 series of 12 knee eccentric extension repetitions (EE)
at 160°/s. The maximal voluntary isometric contraction force of the quadriceps muscle, the …

Twitch potentiation was studied during a fatigue paradigm involving intermittent maximum
voluntary contractions (MVCs) of the tibialis anterior muscle in the elderly and in young …

Methods During separate sessions for the triceps brachii and soleus, 10 young males
performed repetitive shortening contractions with a moderate load (50% of maximum …

Recent data suggest that the potentiated twitch is a more sensitive index of contractile
fatigue than is the unpotentiated twitch. We hypothesized that after a potentially fatiguing …
