There's been a lot of debate whether increasing the time under tensions triggers greater muscle gains, but the majority of studies support this claim under various discoveries: • The cross-section area of the slow - twitch type muscle fibers is greatly increased, which leads to maximal stimulation of these type I fibers since they possess a high level of fatigue threshold, which also promotes an increased hypertrophic response.
This type of training doesn't require a lot of strength, but it does require endurance and mainly uses the slow - twitch fibers, but neglects the fast - twitch type.
Tabata training (and HIIT) both share one great advantage for guys looking to hold onto muscle mass: Unlike traditional steady - state cardio, high - intensity intervals help you build and maintain muscle mass because the fast - twitch fibers — the ones most prone to growth, — are best targeted by this type of training.

Type I fibers are slow twitch and are extremely resistance to fatigue.

As mentioned, fast twitch fibers (the type that make the bulk of our muscle size) respond well to supplemental creatine in the athletic population.
We are attempting to «excite» the Type IIB (fast twitch) fibers by performing a strength - based exercise and then transfer this heightened state into a «synchronized» activity.
Creatine phosphate (creatines high energy molecule form, stored within cells) is used to supply the type 11b muscle fibers (fast - twitch high - glycolytic; the ones that get largest in size) with immediate energy, ensuring these muscles do not prematurely fatigue 6.
For example, sprinters usually have predominately Type IIB fast glycolytic muscle fibers, while distance runners have a larger proportion of slow - twitch, high oxidative muscle fibers.
But first lets clarify, «all muscle fibers» do you mean all types of fibers - fast twitch, slow twitch.
Although many people assume that they are fast twitch muscles, the hamstrings are around 44 — 54 % type I muscle fibers (Dahmane et al. 2005; 2006; Evangelidis et al. 2016), 50 % type I muscle fibers, (Pierrynowski & Morrison, 1985), 55 % type I muscle fibers (Garrett et al. 1984), and even as high as 67 % type I muscle fibers (Johnson et al. 1973).
This leads to describing the muscle fibers as either aerobic / oxidative or anaerobic / glycolytic and ultimately three different fiber types: fast - twitch glycolytic, fast - twitch oxidative, and slow - twitch oxidative (Scott et al. 2001).
