Human skeletal muscle fibers exist across a continuum of slow → fast-twitch. The amount of each fiber type (FT) influences muscle performance but remains largely unexplored in elite athletes, particularly from strength/power sports.

Muscle power is arguably the most sought-after training adaptation, yet only 29 experiments have tested the vastus lateralis FT of male athletes from power sports: judo (1x), soccer (2x), volleyball (1x), sprinters (8x), throwers (3x), bodybuilders (6x),

2019年3月27日 · Human skeletal muscle fibers exist across a continuum of slow → fast-twitch. The amount of each fiber type (FT) influences muscle performance but remains largely unexplored in elite athletes, particularly from strength/power sports.

Muscle biopsy samples were obtained from m. vastus lateralis and m. deltoideus of three high caliber bodybuilders. Tissue specimens were analysed with respect to relative distribution of fast twitch (FT) and slow twitch (ST) fiber types and different indices of fiber area.

2020年3月1日 · Human fast-twitch muscle fibers generate high power in a short amount of time but are easily fatigued, whereas slow-twitch fibers are more fatigue resistant. The transfer of this knowledge to coaching is hampered by the invasive nature of the current evaluation of muscle typology by biopsies.

Selective Muscle Fiber Density Training (SMFDT) – is a targeted approach to performance training that builds a solid foundation to maximize muscle performance potential and work capacity. It accomplishes this by focusing on the unique capacity properties of our two primary types of muscle fibers: fast and slow twitch muscle fibers.

2024年1月18日 · Human skeletal muscle consists of cells known as myocytes, also referred to as muscle fibers. Depending on their contraction speed and metabolic profile, skeletal myocytes can be classified into slow (type I or slow-twitch) and fast (type II or fast-twitch) fibers.

It has been established that excellence in sports with short and long exercise duration requires a high proportion of fast-twitch (FT) or type-II fibers and slow-twitch (ST) or type-I fibers, respectively. Until today, the muscle biopsy method is ...

Spastic Dystonia or hypertonicity is the inability to relax a muscle leading to a spontaneous tonic contraction. Spastic dystonia is most noticeable in humans in the upper limb, where it contributes to the so-called hemiparetic posture, especially in subjects with stroke or cerebral palsy.
