Time Course Evaluation Of Mapk Phosphorylation To Resistance Exercise: A Systematic Review, Justin X. Nicoll, Christopher J. Lee

International Journal of Exercise Science: Conference Proceedings

Mitogen activated protein kinases (MAPK) are intramuscular cell signaling proteins that regulate adaptations to resistance exercise (RE). The MAPKs extracellular signal-regulated kinase 1/2 (ERK1/2), c-jun N-terminal kinase (JNK), p90RSK, and p38-MAPK increase during and after RE. Despite the well-known increase in post-RE phosphorylation responses of MAPK, the time-course and pattern of their activation remains unclear and poorly described. The ability to clearly define phosphorylation patterns during recovery are limited due to the variety of RE protocols implemented and populations tested when investigating MPAK responses to RE. PURPOSE: To systematically review literature on exercise-induced phosphorylation of ERK1/2, JNK, p38-MAPK, and …

Improving Sprint Performance In Road Cycling: The Forward Standing Sprint Position, Paul Franciscus Johannes Merkes

Theses: Doctorates and Masters

The majority of road cycling races finish with a sprint and as such sprints are a key determinant of success. Surprisingly, the scientific literature on this specific topic is scarce, with limited to few studies describing the characteristics of road cycling sprinters and the demands of road sprinting. Cyclists’ sprinting velocity, which is mostly influenced by power output and aerodynamic drag (CdA) is critical to performance outcomes. However, to date, there is very limited research specifically examining how to maximise road sprint velocity. Thus, the overall objective of the four studies outlined in this thesis was to manipulate CdA, physiology, …
