Example 157.6 Exercise researchers compared the effect of different volumes of training on strength gains in the squat exercise. Thirty-three participants performed either one set, four sets, or eight sets of squats. The participants were randomly assigned to each of the groups, and each participant had experience with weight training. The study lasted for 12 weeks, and each participant performed their assigned squat workout twice per week. Participants did not have statistically different one-rep squat maximums before beginning the study. The following result were produced using Minitab (a statistical software package). Interpret the output.
