Associations between Doping Knowledge, -Susceptibility and Substance Use of Austrian Junior Elite Athletes?

Blank C*, Leichtfried

Doping in sport is not only an issue in adult but also in adolescent athletes. Prevention measures shifted from secondary prevention and detection towards primary prevention, often based on education as deterrent for future doping behavior. Prior to developing the latter, target groups need to be identified and their current state of knowledge and doping use, respectively susceptibility needs to be assessed.

Changes in Muscle Activity and Body Sway Over Time During One-Leg Stance

Yu Uchida and Shinichi Demura

It is considered that a one-leg stance (OLS) requires greater lower limb muscle strength and balance than a two-leg stance (TLS), and imposes a burden on the lower limb that progresses with time. This study aimed to compare and examine muscle activity and body sway between the OLS and TLS in young men, focusing on changes over time.

Strategic Differences in Balance Recovery between Athletes and Untrained Individuals

Dmitry Verniba*, William H Gage

Previous research has demonstrated superior balance control among elite athletes, compared with non-athletes, as defined by the ability to maintain static balance; while only few studies investigated dynamic postural control and balance recovery. The objectives of the current study were 1) to examine whether elite athletes demonstrate superior dynamic postural control defined by reduced center of mass (COM) and center of pressure (COP) excursion during balance recovery; and 2) identify balance recovery strategies employed by the athletes.

An Approach to Measure Tibia Movements in Human Locomotion

Yong “Tai” Wang*, Xuanliang Neil Dong

Tibia movements in human gait are three-dimensional (3-D) motions including internal-external rotation, flexion-extension, and abduction-adduction. Due to the nature of marker locations, skin movement, and image lens distortion, it is difficult to accurately measure and assess tibia movements, especially the tibia rotation in a simple and practical way.

Effects of Chronic Omega3- Supplementation on Tendon Structural and Mechanical Properties

Stephen John Pearson* and Syed Robiul Hussain

Omega-3 fatty acids have previously been shown to modulate collagen expression. Given that collagen protein is ubiquitous in connective tissue such as tendons, it is possible that omega-3 can also modify the composition of tendons,resulting in changes to its structural and mechanical properties.
