To compare the effects of three different high intensity training (HIT) models, balanced for total load but differing in training plan progression, on endurance adaptations.


Periodization of exercise is a method typically used in sports training, but the impact of periodized exercise on health outcomes in untrained adults is unclear.

The purpose of this study was to investigate the effect of a chronic dietary periodization strategy on endurance performance in trained athletes.

The present review introduces innovative concepts of training periodization and summarizes a large body of findings characterizing their potential benefits and possible limitations.

The primary aim of this study was to compare two daily undulating periodization (DUP) models on one-repetition maximum (1RM) strength in the squat, bench press, deadlift, total volume (TV) lifted, and temporal hormone response.

Dividing training objectives into consecutive phases to gain morphological adaptations (hypertrophy phase) and neural adaptations (strength and power phases) is called strength-power periodization (SPP). These phases differ in program variables (volume, intensity, and exercise choice or type) and use stepwise intensity progression and concomitant decreasing volume, converging to peak intensity (peaking phase).

Competing at a high level in mixed martial arts (MMA) is the end result of a successful long-term training plan administered over many years. Successful training plans strike a balance between training and recovery. However, this is particularly difficult in MMA because the sport requires technical proficiency in grappling and striking, not to mention a high degree of strength, power, agility, flexibility, and an/aerobic endurance. With so many performance factors to consider, fighters and coach often dedicate too much time to training at the expense of recover. This can lead to underrecovery and increase a fighter’s potential for overtraining. In a worst-case scenario, this can end a fighter’s career before it starts.
