Comparison of Mitochondrial Respiration in M. triceps brachii and M. vastus lateralis Between Elite Cross-Country Skiers and Physically Active Controls.

ABSTRACT:

Rationale

The main purposes of this study were to compare mitochondrial respiration in M. triceps brachii and M. vastus lateralis between elite cross-country (XC) skiers and physically active controls (CON), and to explore the associations between mitochondrial respiration in these muscles and peak oxygen uptake ( V˙ O_2peak) in arm- and leg-dominant exercise modes.

Methods

Thirteen male elite XC skiers (age: 25 ± 4; peak oxygen uptake ( V˙ O_2peak): 75.5 ± 4.2 mL⋅kg^-1⋅min^-1) and twelve CON (age: 26 ± 3; V˙ O_2peak: 57.2 ± 6.4 mL⋅kg^-1⋅min^-1) had microbiopsies taken from M. vastus lateralis and M. triceps brachii, which were analyzed for various measures of mitochondrial respiration using high-resolutio
