Mixed
High-intensity intermittent exercise training induces specific metabolic and structural adaptations, including increased oxidative enzyme activity and faster phosphocreatine resynthesis rates, which significantly enhance fatigue resistance during repeated high-intensity efforts.
To improve your ability to sustain high-intensity efforts, incorporate high-intensity intermittent training into your routine. This type of training, involving short bursts of intense activity with brief recovery, can enhance your muscle's oxidative capacity and phosphocreatine resynthesis rate, leading to better fatigue resistance.
GoodSupportsHIGH confidence
High-intensity training results in increases of both glycolytic and oxidative enzymes, muscle capillarization, improved phosphocreatine resynthesis and regulation of K+, H+, and lactate ions.
Why this rating
The paper is a comprehensive review citing multiple primary studies showing consistent trends in enzyme activity and PCr resynthesis.
