The effect of treadmill-based and track-based walking training on physical fitness in ankle-sprain experienced young people.

The purpose of this study was to evaluate the effects of 12-week treadmill-based (MT) and track-based (TT) walking program on maximal oxygen consumption (VO), muscular endurance, muscle strength, and ankle range of motion (ROM) in ankle sprain experienced young people. Twenty subjects (12 males, 8 females) volunteered to participate in this study and divided into two groups (MT and TT). All subjects completed MT and TT 4 times per week with each session of 60 min with 65% from maximum heart rate. Incremental test on treadmill and 20-m shuttle run test for endurance capacity (VO), 2-km walking test for muscular endurance, vertical jump for strength, and ankle ROM for flexibility were analyzed before and after the training intervention. We found significant increase in incremental, 2-km walking and 20-m shuttle run after both MT and TT. Just after TT were significant increased vertical jump and ankle ROM. In conclusion, TT seems to induce a more positive effect on muscle strength in lower extremity and ankle ROM than treadmill-based walking training in ankle sprain experienced young people.
