Effects Of High-Intensity Position-Specific Drills On Physical And Technical-Skill Performance In Young Soccer Players, Cao Cuong Le

Theses: Doctorates and Masters

Soccer is the most widely played sport in the world, and physical preparation for soccer players has been extensively researched over the years. As the average intensity of a soccer match is close to 80-90% of maximal heart rate (HRmax), it is necessary to train at or above this intensity. Thus, high-intensity interval running and small-sided games are often used to improve aerobic capacity and repeated sprint ability (RSA). However, neither of these approaches consider positional variations in the frequency and type of specific technical skills required in real match situations. Thus, the purpose of this study was to investigate …

The Application Of Maximal Mean And Critical Speed And Metabolic Powers For The Quantification Of External Load In Soccer, Cameron Nicholas Lord

Theses: Doctorates and Masters

In Association football, often referred to as “soccer”, competitive match play is typically known to represent the greatest physical demand that players experience. The demands associated with match running performance may impact training outcomes and injury risk. As a result, practitioners evaluate these demands to ensure that performance is optimised. To assist in this process, global positioning systems (GPS) are typically used to quantify displacement variables and, more recently, the interaction between running speed and acceleration. However, traditional player monitoring methods tend to apply identical and somewhat arbitrary displacement, velocity and acceleration bands to describe movement “intensity”, and thus to …
