The current PhD dissertation revolves around the influence of the number of repetitions per bout
(leading to failure or not) on changes in metabolic and mechanical variables during high-intensity
leg press resistance exercise, to attempt to better understand the mechanical and physiological
aspects underlying resistance training stimuli that affect adaptations. This doctoral thesis is based on
3 scientific studies that have been published in scientific journals. The first study (Chapter 2) was
designed to examine metabolic responses during a single leg press exercise set of 10 repetitions
leading to failure (10RM). Study 2 (Chapter 3) was aimed at examining the influence of the number
of repetitions per set on changes in muscle metabolites and power output during widely used highintensity
intermittent leg press exercise. The last study (Chapter 4) is a descriptive study to
investigate the changes in blood metabolites in relation to muscular metabolites and mechanical
power output changes.
