This document outlines Brooke Marshall's research project investigating the relationship between levels of vigour and passing success rates in female footballers aged 16-25. The project involved collecting data on participants' vigour using a POMS questionnaire and observing their passing success rates during games. Results found a strong positive correlation between higher vigour and higher passing success rates, supporting the first hypothesis. However, no relationship was found between vigour and total passes, not supporting the second hypothesis. The review identifies strengths in standardized instructions and video analysis, but notes weaknesses in only observing one game and lack of inter-rater reliability between observers. Future recommendations include observing multiple games per participant and improving observer reliability.
