Anti-salbutamol antibodies remain as important tools for the detection of salbutamol abuse in athletic doping. This study evaluated the feasibility and efficiency of the chicken (Gallus gallus domesticus) as an immunization host to generate anti-salbutamol scFv antibodies by phage display. A phage display antibody library was constructed from a single chicken immunized against salbutamol-KLH conjugate. After a stringent biopanning strategy, a novel scFv clone which was inhibited by free salbutamol recorded the highest affinity...

Following an initial ankle sprain it is not unlikely that chronic ankle instability (CAI) will develop. CAI is associated with impaired perceived functional and mechanical properties of the ligaments. Nutritional supplementation with collagen peptides has been shown to improve the functional and mechanical properties of the connective tissue. The purpose of this study was to investigate the effectiveness of specific collagen peptide supplementation (SCP) to improve ankle stability in athletes with CAI. 50 male and female athletes with CAI completed a randomized, double-blinded and placebo-controlled study with a daily oral administration of either 5 g SCP or 5 g placebo (Maltodextrin) over a period of six months...

The nutritional intake of ultra-endurance athletes is often poorly matched with the requirements of the sport. Nutrition knowledge is a mediating factor to food choice that could correct such imbalances. Therefore, the purpose of this study was to develop and validate a questionnaire to assess the nutrition knowledge of ultra-endurance athletes. Nutritional knowledge was assessed using a modified sports nutrition questionnaire (ULTRA-Q). Four independent assessors with specialist sports nutrition knowledge confirmed the content validity of the ULTRA-Q...

CONTEXT:   Visual feedback is crucial in the control of human movement. When vision is obstructed, alterations in landing neuromuscular control may increase movements that place individuals at risk for injury. Anterior cruciate ligament (ACL) injury may further alter the motor-control response to alterations in visual feedback. The development of stroboscopic glasses that disrupt visual feedback without fully obscuring it has enabled researchers to assess visual-motor control during movements that simulate the dynamic demands of athletic activity...

This paper utilizes a unique dataset of competitive outcomes from intercollegiate track and field competition to identify the relationship between recent ambient pollution exposure histories and human performance among a young and fit population in a diverse range of physically demanding "tasks". I find that higher contemporaneous ozone levels are associated with poorer performances in events that heavily tax the respiratory system. This is the case despite the low exposure levels observed in the studied sample, which are similar to those regularly experienced across the developed world...

Osteoarthritis (OA) is the most prevalent joint disease characterized by pain and degenerative lesions of the cartilage, subchondral bone, and other joint tissues. The causes of OA remain incompletely understood. Over the years, it has become recognized that OA is a multifactorial disease. In particular, aging and trauma are the main risk factors identified for the development of OA; however, other factors such as genetic predisposition, obesity, inflammation, gender and hormones, or metabolic syndrome contribute to OA development and lead to a more severe outcome...
