As expected, the 'Mars' condition weakened the rats' grip and shrank their calf circumference, muscle weight and slow-twitch fibre content.
They found that the rats that did not receive the red wine compound experienced loss of grip, muscle weight, calf circumference and slow-twitch muscle fiber.
(1998) Events of the excitation-contraction-relaxation (E-C-R) cycle in fast-and slow-twitch mammalian muscle fibres relevant to muscle fatigue.
The soleus and the EDL were selected because the former is a postural muscle with a large number of slow-twitch motor units, while the latter contains a large number of fast-twitch motor units with less motor-unit recruitment in ordinary movements.

Peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1a) is a protein encoded by the PPARGC1a gene, which is involved in mitochondrial biogenesis, fatty acid oxidation, glucose utilization, thermogenesis, angiogenesis and muscle fiber-type conversion toward slow-twitch type I fibers (Ahmetov and Rogozkin, 2009).

To the best of our knowledge, this was the first study to investigate the effects of a passive training with BFR on the morphology and isometric strength of primarily slow-twitch muscle fibers.
Skeletal muscle fibers can be divided into slow-twitch muscle fibers (type I) and fast-twitch muscle fibers (type II) according to MHC subtypes.
The fast twitch fibers hydrolyze ATP faster than slow twitch and have greater reactivity in the presence of a basic pH, contrary to acidic pre-incubations in which slow-twitch fibers present a more intensity of reaction (Kalmar et al., 2012; Latorre et al., 1993).
Muscle fibers can be grouped into three major categories: slow-twitch type I fibers with high capillary density and high oxidative capacity adapted to endurance exercise, fast-twitch fibers type IIb, which have low capillary density and low oxidative capacity ideal for sprint and anaerobic performance, and type IIa fibers that show intermediate characteristics [13].
