We investigated the influence of immediate post-exercise dietary supplementation on the subsequent food consumption pattern and endurance exercise performance in physically trained individuals. On two occasions, trained male cyclists performed a glycogen-depleting exercise bout followed by a 2-hour nutritional supplementation period, 28 hours of free-living recovery, and a subsequent 40-km cycling time trial. During the 2-hour post-exercise supplementation, subjects consumed equal volumes of reduced-fat chocolate milk (CM) or a sports beverage (SB) in a single-blind, randomized design...

Endurance athletes use nutritional guidelines and supplements to improve exercise performance and recovery. However, use is not always based on scientific evidence of improved performance, which type of athlete would benefit most, or the optimal dose and timing of a particular supplement. Health professionals that give advice to athletes need to target their recommendations on the energy systems and muscle fiber types used for the athlete's sporting event, the goal of the training block, the time of the competitive season, and the characteristics and food preferences of the individual athlete...

A novel kinetic method was developed for the quantitation of α-ketoglutaric acid (AKG) in cardioplegic solution and athletic supplements. The assay relied on an enzymatic transamination of AKG and d-4-hydroxyphenylglycine to form 4-hydroxybenzoylformic acid and l-glutamic acid using d-phenylglycine aminotransferase. Since 4-hydroxybenzoylformic acid absorbed UV strongly at 334 nm, the initial rate of the reaction was determined by the increasing absorbance at this wavelength without the need for colorimetric probes or coupling reactions, and this information was used for the construction of a standard curve against AKG concentration...

Blood alkalosis, as indicated by an increased blood bicarbonate concentration and pH, has been shown to be beneficial for exercise performance. Sodium bicarbonate, sodium citrate, and sodium or calcium lactate, can all result in increased circulating bicarbonate and have all independently been shown to improve exercise capacity and performance under various circumstances. Although there is considerable evidence demonstrating the efficacy of these supplements in several sports-specific situations, it is commonly acknowledged that their efficacy is equivocal, due to contrasting evidence...

BACKGROUND AND PURPOSE: Dizziness and balance problems are common symptoms following sports-related concussion (SRC). Most sports require high-level balance skills that integrate the sensory inputs used for balance. Thus, a comprehensive assessment of postural control following SRC is recommended as an integral part of evaluation and management of the injury. The purpose of this exploratory study was to examine performance differences between uninjured and concussed athletes on the Concussion Balance Test (COBALT), as well as complete preliminary analyses of criterion-related validity and reliability of COBALT...

Nowadays, daily food supplementation regarding the improvement of physical and mental performance is a growing trend in sport practitioners, young students and active people. Food supplements are foodstuffs, labeled under food law and not obliged to safety assessments before their commercialization. Several products are commercialized claiming ergogenic effects as marketing strategies. Caffeine is often one of their main ingredients, as it increases both physical performance and concentration. This manuscript presents a general overview of the current caffeine-based food supplements and energy drinks available in the Portuguese market, as well as the consuming trends regarding their ergogenic effects, performance purposes, and active ingredients...

REVIEW
Erin K Contino
Joint disease is one of the most common issues effecting sport horses. Because there is no cure for joint disease, treatment goals surround slowing progression of the disease, minimizing pain, increasing function, and optimizing performance. Accomplishing these goals often requires a multimodal approach that combines systemic medications or supplements; intra-articular therapies, such as corticosteroids or biologics; management considerations; and physical therapy exercises.

Traumatic and overuse hip injuries occur frequently in amateur and professional athletes. After clinical assessment, imaging plays an important role in diagnosis and in defining care management of these injuries. Ultrasonography (US) is being increasingly used in assessment of hip injuries because of the wide availability of US machines, the lower cost, and the unique real-time imaging capability, which allows both static and dynamic evaluation as well as guidance of point-of-care interventions such as fluid aspiration and steroid injection...
