Objectives: Following the development of the Sport Imagery Ability Questionnaire (SIAQ; Williams & Cumming, 2011), the aim of the present two studies was to more comprehensively examine the relationship between sport-related imagery ability and the functions of imagery and observational learning (OL) athletes report. A second aim was to establish the SIAQ’s predictive validity. Design: Two samp...

BACKGROUND Limited research exists on the effect of a sports dietitian (SD) on athletes' dietary habits and nutrient periodization, which is the deliberate manipulation of macronutrient intake to match training goals. Further, the difference in dietary habits between men and women collegiate athletes has been understudied. A survey questionnaire examining dietary habits and practices was admini...

We studied prospectively 22 young athletes who had undergone surgical treatment for lumbar spondylolysis. There were 15 men and seven women with a mean age of 20.2 years (15 to 34). Of these, 13 were professional footballers, four professional cricketers, three hockey players, one a tennis player and one a golfer. Preoperative assessment included plain radiography, single positron-emission CT, ...

Muscle motor unit numbers decrease markedly in old age, while remaining motor units are enlarged and can have reduced neuromuscular junction transmission stability. However, it is possible that regular intense physical activity throughout life can attenuate this remodeling. The aim of this study was to compare the number, size, and neuromuscular junction transmission stability of tibialis anter...

Several factors, including nutritional status and dietary pattern are paramount to optimum performance among athletes. Notwithstanding, risky behaviours that limit or impair athletic performance are widely prevalent among athletes; these include excessive weight reduction and inappropriate dietary practices. This study was conducted to provide information on the nutritional status and dietary p...

BACKGROUND Rotator cuff tears are rare injuries in adolescents but cause significant morbidity if unrecognized. Previous literature on rotator cuff repairs in adolescents is limited to small case series, with few data to guide treatment. HYPOTHESIS Adolescent patients would have excellent functional outcome scores and return to the same level of sports participation after rotator cuff repair ...

This study examined the cardiac structure and function of a unique cohort of documented lifelong, competitive endurance veteran athletes (>50 yr). Twelve lifelong veteran male endurance athletes [mean ± SD (range) age: 56 ± 6 yr (50-67)], 20 age-matched veteran controls [60 ± 5 yr; (52-69)], and 17 younger male endurance athletes [31 ± 5 yr (26-40)] without significant comorbidities underwent c...

To the Editor: Competitive sports participation for athletes with long QT syndrome (LQTS) is guided by the 36th Bethesda Conference, which recommends that patients with either (1) symptoms, (2) a corrected QT interval (QTc) greater than 470 milliseconds (males) or 480 milliseconds (females), or (3) an implantable cardioverter-defibrillator (ICD) not participate in most sports. The European Soci...
