Abstract: Hypertrophic cardiomyopathy is a genetic heart condition occurring in up to 1 in 200 patients in the United States, many of whom are young and otherwise healthy. This condition puts those affected at increased risk for adverse cardiac outcomes, including sudden cardiac arrest and death, with particular concern for this to occur during exercise and other forms of exertion. Recent studies aimed at evaluating the risk of exercise in hypertrophic cardiomyopathy patients have suggested that moderate and even vigorous exercise may be safe for certain patients. Clinical guidelines are changing to reflect this recent information and to encourage a shared decision-making approach, which can allow more hypertrophic cardiomyopathy patients to participate in health-promoting exercise activities.

Abstract: Exercise leads to robust cardiovascular, musculoskeletal, and psychological benefits that improve quality of life and longevity for older adults, but accompanying improvements in athletic parameters are less well explored. The aim of this review is to summarize some of the most common exercise modalities, namely, Pilates, martial arts (tai chi, Japanese-style karate, hard martial arts), locomotion (brisk walking/jogging and running), Masters sports, resistance training, and high-intensity interval training, in improving athletic performance for older adults. Regular participation in these activities can have robust yet unique impacts on physical performance that prolong exercise participation. In particular, this review will explore benefits in cardiorespiratory fitness, power, strength, flexibility, and balance, thereby hopefully improving endurance, exercise adherence, and overall fall risk. A narrative literature review was performed to explore benefits, pitfalls, and recommendations for some of the most popular exercise modalities for older adults.

Abstract: A 72-year-old male presented for evaluation of a 2-wk history left buttock pain that began while playing pickleball. He sustained a left inversion ankle sprain while in a squatted position and landed on his left buttock. Four days after his injury, he developed extensive bruising involving his lower back, buttock, and left thigh. On examination, he had tenderness to palpation at the left side of the sacrum and in the region of the deep external rotators. Left hip range of motion was full in extension but limited to 90° of flexion, which reproduced left-sided buttock pain. External rotation provoked pain, but internal rotation was full and pain free. MRI of the pelvis demonstrated a grade 2 partial thickness tear of the left gluteus maximus muscle at its distal myotendinous junction with associated retraction and intramuscular hematoma. He was managed with compression with biking shorts, icing, acetaminophen, and physical therapy. He returned to pickleball approximately 4 wk after his injury, and at his 4-wk follow-up, he reported 99% improvement in his symptoms with the only remaining complaint being minimal discomfort with gluteal stretching.

Abstract: Muscle injury in sport results in significant lost time and potential for reinjury for athletes. Autologous blood product, namely, platelet-rich plasma (PRP), has been investigated for possible augmentation of the treatment timeline with prevention of reinjury; however, conflicting results have been identified. A growing body of basic science and clinical literature is forming that supports the use of platelet-poor plasma (PPP) for muscle injury. The purpose of this study was to provide a background of the basic science of PRP versus PPP for muscle injury and to identify and review the clinical evidence for both autologous blood products, including the author's clinical experience utilizing the blood products. At the tissue level, PRP causes myoblast proliferation while PPP has led to myoblast induction, potentially identifying improved native muscle healing. Conflicting studies have been identified for the use of PRP for muscle injury. A growing body of positive results for PPP was identified, but high-quality comparative studies are needed.

Abstract: Hip pain is a common concern among athletes. With gluteal tendinopathy, femoroacetabular impingement, and osteoarthritis predominating sports medicine and musculoskeletal practices, less common etiologies may be overlooked. Complex pelvic anatomy and variable pain referral patterns may make identifying an accurate diagnosis challenging. Employing a systematic approach to evaluation and having a thorough understanding of hip region anatomy are essential. A potentially overlooked cause of anterolateral hip pain is iliotibial band origin tendinopathy. Patients often present with pain around the anterolateral hip and tenderness to palpation at the anterolateral iliac crest. While patients with iliotibial band origin tendinopathy usually respond to nonsurgical intervention, there is little literature to guide evaluation and treatment, highlighting a gap in the recognition of this condition. The purpose of this narrative review is to describe the anatomy of the proximal iliotibial band origin, outline the clinical diagnosis and imaging findings of ITBOT, and summarize current treatment options.

Abstract: Achilles tendinopathy is a common overuse injury that is traditionally managed with activity modification and a progressive eccentric strengthening program. This narrative review describes the available evidence for adjunctive procedural interventions in the management of midportion and insertional AT, specifically in the athletic population. Safety and efficacy data from available literature on extracorporeal shockwave therapy, platelet-rich plasma, high-volume injectate with or without tendon scraping, and percutaneous needle tenotomy are used to propose an algorithm for treatment of Achilles tendinopathy for the in-season athlete.

Abstract: Ultramarathon open water swimming (OWS) events are one of the toughest endurance challenges in the world. The sport has gained notoriety with athletes swimming across the English Channel, Diana Nyad swimming from Cuba to Florida, and the 5- and 10-km OWS in the Olympic schedule. The athletes who participate are exposed to dangerous conditions that expose risks inherent to the sport. The optimal time to prepare for an emergency is before it happens. The aim of this paper is to present an emergency action plan (EAP) designed for the "Swim Tuff" event, a record-breaking ultramarathon swim that took place in Rhode Island, United States. This article identifies an overview of Swim Tuff, the challenges experienced, and how the team designed and implemented risk mitigation strategies. The professionals looking over athletes completing an OWS should be educated and aware of the unique circumstances inherent to the sport.
