Today’s nutrition and workouts primarily stress slow twitch endurance fibers, which - while beneficial - limit muscle size.
Fast twitch explosive fibers are harder to recruit, sustain more damage and require longer recovery. But
fast twitch fibers have 30% greater growth capacity! Fast Twitch™ Power Workout Drink
fuels intense, fast twitch contracting workouts in two ways: by
boosting nitric oxide (NO) levels and encouraging formation of the high-energy molecule creatine phosphate. Fast Twitch™ Power Workout Drink puts you in the
intensity zone to fuel total muscle fiber contractions and enables muscles to
produce more power during workouts, and grow larger after. Plus, intensity zone workouts
raise metabolism, increasing fat loss significantly more than easier workouts.
Muscle Fact
Fast and slow twitch are generalizations for more specific muscle fiber types. Physiologists classify human muscle fibers as Type I (slow twitch; slow oxidative, SO), IIa (fast twitch; fast oxidative glycolytic, FOG), IIab (intermediate fiber), and IIb or x (fast twitch; fast glycolytic, FG). In general, slow twitch fibers are relatively fatigue resistant, but do not contract as rapidly or as strongly. Fast-twitch fibers contract more rapidly and forcefully, but fatigue more quickly. Although all fiber types respond to intense training, fast twitch fibers tend to have a greater ability for hypertrophy (growth).
