Practice Questions

Question 1

A researcher is investigating the impact of a new high-intensity interval training (HIIT) protocol on maximal oxygen uptake ($VO_{2max}$) in collegiate athletes. They collect $VO_{2max}$ data before and after a 6-week intervention. To account for individual variability and the repeated measures design, which statistical test is most appropriate for analyzing the change in $VO_{2max}$ within the same group of athletes?

Question 2

When critically appraising a study's methodology, a significant concern arises if the study lacks a clear description of how participants were recruited and assigned to groups. This omission primarily impacts which aspect of the study's rigor?

Question 3

A meta-analysis is performed to synthesize the effects of various resistance training programs on muscle hypertrophy. The pooled effect size (Hedges' $g$) is reported as $0.65$ with a $95\%$ confidence interval of $[0.40, 0.90]$. What is the most accurate interpretation of these findings?

Question 4

In the context of evidence-based practice, a clinician encounters a patient with a specific musculoskeletal injury. Before implementing an intervention, the clinician formulates a PICO question. Which component of the PICO framework would address the specific intervention being considered (e.g., a particular exercise therapy)?

Question 5

A research study aims to determine if there is a difference in body composition (measured by DEXA scan) between athletes who follow a vegan diet and those who follow an omnivorous diet. Participants are recruited from various athletic clubs and categorized into one of the two dietary groups. Which statistical test would be most appropriate to compare the mean body fat percentage between these two independent groups?
