Older adults often suffer an accidental fall when navigating challenging surfaces during common locomotor tasks, such as walking and ascending stairs. This study examined the effect of slick and uneven surfaces on lower limb joint work in older and younger adults while walking and ascending stairs. Fifteen young (18–25 years) and 12 older (>65 years) adults had stance phase positive limb and joint work quantified during walking and stair ascent tasks on a normal, slick, and uneven surface, which was then submitted to a two-way mixed model ANOVA for analysis. The stair ascent required greater limb, and hip, knee, …

The goal of KINES 432 Conditioning Procedures is for students to develop the skills to appropriately prescribe exercise and conditioning that will enhance the student’s ability as a practitioner to help others improve conditioning and achieve their health, fitness, and performance goals. The focus is on program objectives, planning, exercise analysis, and prescription as well as the supporting theories, rationale, and research. Application of concepts occurs via projects, service-learning and laboratory experiences. KINES 432 is also designated a university Finishing Foundations course. Boise State University’s Foundational Studies Program provides undergraduates with a broad-based education that spans the entire university experience. …

The purpose of this study was to investigate muscle activation patterns during a landing task in boys and girls through the use of muscle synergies. Electromyographical (EMG) data from six lower extremity muscles were collected from 11 boys and 16 girls while they performed single-leg drop-landings. EMG data from six leg muscles were rectified, smoothed, and normalized to maximum dynamic muscle activity during landing. Data from 100 ms before to 100 ms after touchdown were submitted to factor analyses to extract muscle synergies along with the associated activation and weighing coefficients. Boys and girls both used three muscle synergies. The …

Rapid acceleration, deceleration, landing and change of direction have been implicated as mechanisms of noncontact anterior cruciate ligament (ACL) injury. PURPOSE: To examine the ground reaction forces occurring to the knee during non-fatigued and fatigued jump, land and cut maneuvers in three unplanned cutting directions. METHODS: Eleven healthy, adult female collegiate soccer athletes participated in this study (age= 20.3±0.9 years; height= 167.4±4.8 cm; mass= 63.7±7.7 kg). Each subject was instructed to perform 9 jump, land, and cut maneuvers in a pre-fatigued state and fatigued state. The protocols were randomly assigned to include 3 cuts in each of the three directions. …

Process Oriented Guided Inquiry (POGIL) uses cooperative learning activities to teach content and to actively engage students in inquiry, analytical thinking, and teamwork. It has been used extensively in Chemistry education, but its use is not well documented in other areas. This is a summary of the initial implementation of POGIL in a university biomechanics course and includes the benefits, challenges, and recommendations for teachers interested in using this effective instructional strategy.
