Individual physiological and mitochondrial responses during 12 weeks of intensified exercise.

ABSTRACT:

Aim

Observed effects of exercise are highly variable between individuals, and subject-by-training interaction (i.e., individual response variability) is often not estimated. Here, we measured mitochondrial (citrate synthetase, cytochrome-c oxidase, succinate dehydrogenase, and mitochondrial copy-number), performance markers (W_peak , lactate threshold [LT], and VO_2peak ), and fiber type proportions/expression (type I, type IIa, and type IIx) in multiple time points during 12-week of high-intensity interval training (HIIT) to investigate effects of exercise at the individual level.

Methods

Sixteen young (age: 33.1 ± 9.0 years), healthy men (VO_2peak 35-60 ml/min/kg and BMI: 26.4 ± 4.2) from the Gene SMART study completed 12-week of progressive H
