Self-optimization of Stride Length Among Experienced and Inexperienced Runners

International Journal of Exercise Science 10(3): 446-453, 2017. Experienced runners appear to naturally select a stride length which is optimal for minimizing oxygen uptake. However, whether this ability is naturally built into the human body or whether it is learned through experience has not been previously tested. This study investigated whether inexperienced runners are as ...

The Relationship of Living Environment with Behavioral and Fitness Outcomes by Sex: an Exploratory Study in College-aged Students

International Journal of Exercise Science 10(3): 330-339, 2017. Although physical activity (PA) is associated with several health benefits, there is a marked decline during college years, which is an influential period for the development of health behaviors. This study examined the relationship of neighborhood and living environment with behavioral (PA and sedentary behavior) and ...

The Accuracy of Pedometers in Measuring Walking Steps on a Treadmill in College Students

The hypothesis was ...

The Effect Of High Intensity Interval Run Training On Cross Sectional Area Of The Vastus Lateralis In Untrained College Students

International Journal of Exercise Science 10(1): 137-145, 2017 Aerobic cycling has been repeatedly shown to induce hypertrophy in skeletal muscle across a variety of populations, while there has been a lack of investigation into the impact of running upon hypertrophy. An increasingly popular model of aerobic exercise is high-intensity interval training (HIIT); in addition to its ...
