In other words, each participant had testing days with each of the three rolling levels, and the order of which testing days had which rolling depth were randomized. The RM intervention consisted of three 60-second bouts of RM with two minutes between each bout. Each 60-second RM bout consisted of 15 four- second passes paced with a metronome. Each pass began just above the knee at the distal end of the quadriceps, rolled up the thigh to the participant's hip crease, and reverse rolled back to the starting point. The low, moderate, and high RM depths were determined per participant on each testing day prior to warm-up based on the weighted load for RM that reached a 10 out of 10 on that individual's rate of perceived pain. The low RM level was 50 percent of the applicable day's maximum weight measurement, while the moderate RM level was 70 percent and the high RM level was 90 percent of the applicable day's maximum weight measurement. RM pressure consistency was kept by using a specially designed pressure roller apparatus to deliver the intervention, using weighted plates for the pressure load. Study outcome measures were active and passive ROM, muscle strength in the form of knee extension and flexion maximum voluntary isometric contraction This study's findings align with other research that indicates R M improves ROM and does not negatively affect muscle strength or performance.
