Monitoring an athlete's energy intake and energy expenditure (EE) is an important consideration of nutritional planning for sport conditioning and peak performance. In order to provide appropriate recommendations regarding nutritional requirements and caloric needs, an accurate determination of energy requirements is necessary. By knowing an individual's EE, a coach, athletic performance staff or trainer can effectively determine training loads and volumes necessary for periodization and seasonal planning for a particular sport...

Graft failure rates were higher and inferior subjective outcomes were observed after anterior cruciate ligament reconstruction in patients with generalized hypermobility. This is a clear and corroborative finding that is highly consilient with other reports of similar studies from the published literature. However, controversy remains regarding other potentially predictive and confounding variables. For example, age, activity level, sex, and dynamic neuromuscular control were not considered in this interesting, important, and potentially impactful study...

One of the most commonly injured structures of the thumb metacarpophalangeal (MCP) joint is the ulnar collateral ligament (UCL). An acute injury of this ligament is often amenable to primary repair. Despite the favorable outcomes of primary repair, the thumb is often restricted during initial healing of the ligament with immobilization and delayed rehabilitation. We present a novel technique to augment the repair of the UCL with suture tape to provide immediate biomechanical support and strength during the critical time of ligament healing...

Time of day is a key factor that influences the optimization of athletic performance. Intercollegiate coaches oftentimes hold early morning strength training sessions for a variety of factors including convenience. However, few studies have specifically investigated the effect of early morning vs. late afternoon strength training on performance indices of fatigue. This is athletically important because circadian and/or ultradian rhythms and alterations in sleep patterns can affect training ability. Therefore, the purpose of the present study was to examine the effects of morning vs...
