Previous varsity sport injury research has analyzed how acute and chronic injury severity, type, and location differs between sport and sexes, with limited research in time to injury. Canadian university varsity sport injury research is especially sparse and mostly retrospective. Thus, we aimed to understand injury differences in male and female competitive university athletes competing in the same sport. Athletes who competed on the basketball, volleyball, soccer, ice hockey, football (male), rugby (female), and wrestling teams were eligible for the study...

Homograft heart valves may have significant advantages and are preferred for the repair of congenital valve malformations, especially in young women of childbearing age, athletes and in patients with active endocarditis. A growing problem, however, is the mismatch between tissue donation and the increasing demand. The aim of this paper is to describe the initiation process of a homograft procurement program to attenuate the shortage of organs. A comprehensive description of the infrastructure and procedural steps required to initiate a cardiac and vascular tissue donation program combined with a prospective follow-up of all homografts explanted at our institution...

High carbohydrate, low fat (HCLF) diets have been the predominant nutrition strategy for athletic performance, but recent evidence following multi-week habituation has challenged the superiority of HCLF over low carbohydrate, high fat (LCHF) diets, along with growing interest in the potential health and disease implications of dietary choice. Highly trained competitive middle-aged athletes underwent two 31-day isocaloric diets (HCLF or LCHF) in a randomized, counterbalanced, and crossover design while controlling calories and training load...

The incidence of knee injuries in sport, particularly involving the ACL, appears to be increasing yearly, especially in younger age athletes. Even more concerning is the frequency of ACL reinjury also appears to be increasing year after year. Improving the objective criteria and testing methods used to determine return to play (RTP) readiness following ACL surgery is one aspect of the rehabilitation process that can significantly help in reducing reinjury rates. Currently, the majority of clinicians are still using post operative time frames as their number one criterion for clearance to RTP...

Grip strength (GS) is correlated with major muscle group strength; weakness and asymmetry in older adults are predictive of future disease and functional limitation risk. GS at different ages and hand symmetry for Olympic-style weightlifters and their association with performance have not been established. GS was measured in 164 athletes participating in the 2022 World Master Weightlifting Championships. The objectives wereto study the magnitude of the age-associated decline in GS in weightlifters and the association of GS with weightlifting performance...

OBJECTIVE: Characterize the levels of various metrics of repetitive head impacts (RHI) in contact (CS) and non-contact (NCS) sport athletes and determine the extent to which they are associated with fluid cognition. METHODS: Collegiate-aged athletes (n = 176) completed semi-structured interviews about participation in contact sport. RHI was operationalized based on current sport (CS/NCS), the cumulative number of years of participation, age at first exposure (AFE), and based on recently proposed traumatic encephalopathy syndrome (TES) categories...

Human skeletal muscle demonstrates remarkable plasticity, adapting to numerous external stimuli including the habitual level of contractile loading. Accordingly, muscle function and exercise capacity encompass a broad spectrum, from inactive individuals with low levels of endurance and strength to elite athletes who produce prodigious performances underpinned by pleiotropic training-induced muscular adaptations. Our current understanding of the signal integration, interpretation, and output coordination of the cellular and molecular mechanisms that govern muscle plasticity across this continuum is incomplete...

BACKGROUND: Whether cardiovascular (CV) risk factors might impact Left Ventricular (LV) mass in athletes is unknown. METHODS: The impact of CV risk factors (Total/LDL cholesterol, triglycerides, positive family history, smoking, body fat, blood pressure), constitutional characteristics (age, sex, body mass index) and type of sport was assessed in 1111 Olympic athletes. RESULTS: Multivariate logistic regression analysis demonstrated a significant impact: BMI ≥ 30 kg/m2 (odds ratio [OR] = 2...

Systematic, regular high-volume endurance training induces significant metabolic adaptations in glucose and lipids metabolism, which seems to affect the negative impact of unhealthy nutrition, at least in animal models. The present study aimed to investigate the main determinants of body composition, blood glucose and lipids concentrations between middle-aged sedentary individuals (Sed) and well-trained endurance athletes (Run), both following an unhealthy high-fat diet. In thirty-five Sed (Age: 54.0 ± 6.6 yrs, Body Mass: 77...

OBJECTIVE: Identify the effects of multi-directional, high intensity exercise on VOMS symptom scores in male and female recreational, college-aged athletes. DESIGN: Cross-sectional study. SETTING: Athletic Therapy facility. PARTICIPANTS: A convenience sample of 29 (15 females, 14 males; 21.48 ± 1.40 years old) healthy recreational athletes. MAIN OUTCOME MEASURES: VOMS symptom scores pre, immediately post-, and 10 min post a multidirectional, high intensity intermittent exercise protocol (HIIP)...

Older adults have higher cerebrovascular impedance than young individuals which may contribute to chronic brain hypoperfusion. Besides, middle-aged athletes exhibit lower cerebrovascular impedance than their sedentary peers. We examined whether aerobic exercise training (AET) reduces cerebrovascular impedance in sedentary older adults. We conducted a proof-of-concept trial that randomized 73 older adults to 1 yr of AET ( n = 36) or stretching and toning (SAT, n = 37) interventions. Cerebrovascular impedance was estimated from simultaneous recordings of carotid artery pressure (CAP) via applanation tonometry and cerebral blood flow velocity (CBFV) in the middle cerebral artery via transcranial Doppler using transfer function analysis...

OBJECTIVE: To identify normative near point of convergence (NPC) data for healthy high-school-aged athletes (13-19 years old) and determine the percentage of individuals with NPC scores that fall outside the currently accepted clinical cutoff value of 5 cm. Another objective was to determine the relationship between sex, concussion history, and attention deficit disorder/attention deficit hyperactivity disorder (ADD/ADHD) with NPC scores, if any. DESIGN: Case series...

Mild left ventricular hypertrophy (LVH) has been considered as one of the possible structural, physiological adaptations to regular, intensive physical activity. However, it may also appear as one of the subclinical complications of hypertension. In athletes, the differential diagnosis between these two entities may be complicated as regular physical activity may potentially mask the presence of arterial hypertension. We sought to determine the relation between LVH in middle-age athletes and the presence of hypertension...

BACKGROUND: The Kerlan-Jobe Orthopaedic Clinic Shoulder & Elbow Score (KJOC) provides questions for the overhead athlete that can aid with determining if someone is throwing with or without pain. However, this scale was initially created for the adult baseball athlete and has not been validated for younger male demographics. HYPOTHESIS/PURPOSE: To (1) determine if the scores on the KJOC are different between those throwing with and without pain in male youth and high school-aged baseball athletes, and (2) establish a prediction score for whether a young baseball athlete is throwing with symptoms...

BACKGROUND: There is a paucity of information in the literature on midterm outcomes from the arthroscopic treatment of femoroacetabular impingement syndrome (FAIS) with concomitant labral treatment in patients with mild osteoarthritis (OA) using modern surgical techniques. PURPOSE: To compare outcomes of hip arthroscopy for the treatment of FAIS between patients with mild OA (Tönnis grade 1) and patients without OA (Tönnis grade 0) at minimum 5-year follow-up...

Larkin, P, Sortino, B, Carlon, T, Saunders, T, and Pane, C. Gender- and sport-specific normative anthropometric and physical values in talent-identified high school athletes. J Strength Cond Res 37(3): 606-615, 2023-Youth sport is associated with the identification and promotion of athletes within talent development pathways, with anthropometric and physical performance measures being key assessment and monitoring tools. To adequately evaluate performance within a population, normative reference data are needed; however, currently, there is limited normative values of talent-identified youth athletes...

OBJECTIVE: The objective of this study was to determine the utility of "standard" cardiac screening with EKG, echocardiography, and serum troponin T (hs-Tn T) testing after COVID infection in competitive college athletes. DESIGN: Prospective cohort study. SETTING: Tertiary cardiology clinic, university training room. PARTICIPANTS: Sixty-five Division 1 athletes recovered from COVID-19 and 465 controls. ASSESSMENT: All COVID-recovered athletes underwent cardiac screening on return to campus in fall 2020...

Recently, buccal epithelium has been used to study age-dependent processes. This approach is of particular relevance due to its non-invasiveness. The purpose of this study is to establish the normal values of the buccal cytogram in different age groups, including athletes. 200 practically healthy volunteers of different ages were examined, who were divided into 5 groups in accordance with the WHO age classification. In addition, 125 professional athletes took part in the study. All patients underwent a comprehensive dental examination and a standard cytological examination of buccal smears...

BACKGROUND: Master athletes (MAs), or athletes older than 40 years, make up a patient population whose outcomes after primary arthroscopic hip surgery are largely unknown. PURPOSE: To report minimum 2-year outcomes of MAs after primary hip arthroscopy and compare their results to a propensity-matched nonathlete (NA) control group. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Data were prospectively collected between February 2008 and April 2019 and retrospectively reviewed for all patients who underwent primary hip arthroscopy...

OBJECTIVE: Concussion can cause deficits in balance and gait. Much of what is known about how concussion affects balance and gait has been derived from studies involving youth, high school, and university-aged athletes. However, investigation into the effects of concussion on balance and gait in community-dwelling young, middle, and older age adults is limited. This study aimed to present descriptive reference values for common balance and gait measures in community-dwelling adults between the ages of 20 and 69 years with concussion...
