The annual incidence of sudden cardiac death (SCD) in athletes is significantly lower than the general population. However, when SCD occurs in an athlete during sporting event or training, it sends shockwaves in the society and raises questions about cardiovascular effects of sports and exercise. This document reviews the causes and mechanism of SCD in sports and exercise in young and older athletes. In the Indian context, we suggest a 'pre-participation screening' of young and older athletes and consider a 'supervised, graded exercise regime' for the uninitiated, older sports participant...

The relationship between age and elite marathon race times is well investigated, but little is known for half-marathon running. This study investigated the relationship between half-marathon race times and age in 1-year intervals by using the world singe age records in half-marathon running and the sex difference in performance from 5-91 years in men and 5-93 years in women. We found a 4 th order-polynomial relationship between age and race time for both women and men. Women achieve their best half-marathon race time earlier in life than men, 23...

REVIEW
Pamela Douglas, Donna Geddes
BACKGROUND: breastfeeding optimises health outcomes for both mothers and infants. Although most women want to breastfeed, they report commencing infant formula because of nipple pain, unsettled infant behaviour, and infant growth concerns. To date, existing approaches to fit and hold ('latch and positioning') have been demonstrated not to help breastfeeding outcomes, and women report widespread dissatisfaction with the quality of support and conflicting advice they receive. Breast and nipple pain, difficulty with latching and sucking, fussing at the breast, back-arching, marathon feeds, excessively frequent feeds, poor weight gain, breast refusal, and crying due to poor satiety often signal suboptimal positional instability and impaired milk transfer, but may be misdiagnosed as medical conditions...

Summary: Copy number variation is an important and abundant source of variation in the human genome, which has been associated with a number of diseases, especially cancer. Massively parallel next-generation sequencing allows copy number profiling with fine resolution. Such efforts, however, have met with mixed successes, with setbacks arising partly from the lack of reliable analytical methods to meet the diverse and unique challenges arising from the myriad experimental designs and study goals in genetic studies...

This study examined how experienced and anticipated pride and shame were related to time spent training and effort expended toward training the following week. Participants (N = 158, 76% women; Mage = 35.51, SD = 10.29 years) training for a marathon/half-marathon completed a weekly online questionnaire for 5 weeks leading up to a race. In the multilevel models, time spent training was positively predicted by race proximity, age, and effort expended that week. Effort expended toward training was predicted by the current week's effort, the amount of time spent training that week, and was greater for participants who usually reported experiencing more pride than others...

Objectives: While the health benefits of running are legitimately advocated, participation in running can also lead to health problems. There is a high range of reported prevalence rates especially of running-related overuse injuries in high-level athletes and during competition. Little consensus exists for acute injuries and illnesses especially in recreational runners. Therefore, the aim of this study was to record the prevalence of health problems in recreational long-distance runners preparing for an event...

Objectives: Traditional performance tests in mountain bike marathon (XCM) primarily quantify aerobic metabolism and may not describe the relevant capacities in XCM. We aimed to validate a comprehensive test protocol quantifying its intermittent demands. Methods: Forty-nine athletes (38.8±9.1 years; 38 male; 11 female) performed a laboratory performance test, including an incremental test, to determine individual anaerobic threshold (IAT), peak power output (PPO) and three maximal efforts (10 s all-out sprint, 1 min maximal effort and 5 min maximal effort)...

Participants in the Ultrarunners Longitudinal TRAcking (ULTRA) Study were asked to answer "yes" or "no" to the question "If you were to learn, with absolute certainty, that ultramarathon running is bad for your health, would you stop your ultramarathon training and participation?" Among the 1349 runners, 74.1% answered "no". Compared with those answering "yes", they were younger (p < 0.0001), less likely to be married (p = 0.019), had less children (p = 0.0095), had a lower health orientation (p < 0...

This study aimed to identify the similarities and differences among half-marathon runners in relation to their performance level. Forty-eight male runners were classified into 4 groups according to their performance level in a half-marathon (min): Group 1 (n = 11, < 70 min), Group 2 (n = 13, < 80 min), Group 3 (n = 13, < 90 min), Group 4 (n = 11, < 105 min). In two separate sessions, training-related, anthropometric, physiological, foot strike pattern and spatio-temporal variables were recorded...

A 41-year-old healthy man presented with sudden disturbance of consciousness and convulsion during a marathon. Computed tomography revealed a lateral sinus sign in the posterior fossa, and magnetic resonance(MR)venography revealed a flow gap in the posterior part of the superior sagittal sinus and bilateral transverse sinus, although the other MR image sequences were normal. Laboratory data revealed dehydration, acute kidney failure, and rhabdomyolysis. Owing to immediate correction of dehydration, clinical symptoms and radiological abnormality improved rapidly...

PURPOSE: This study was conducted to test, in mountain running route conditions, the accuracy of the Polar V800™ monitor as a suitable device for monitoring the heart rate variability (HRV) of runners. METHOD: Eighteen healthy subjects ran a route that included a range of running slopes such as those encountered in trail and ultra-trail races. The comparative study of a V800 and a Holter SEER 12 ECG Recorder™ included the analysis of RR time series and short-term HRV analysis...

OBJECTIVES: Pacing strategies have mainly been investigated for runners, but little is known for cross-country skiers. The aim of the present study was to investigate whether differences in pacing strategies do exist between younger and older cross-country skiers competing in the 42km 'Engadin Ski Marathon'. METHODS: Pacing was studied in 105,565 cross-country skiers (classified in 5-year age groups) competing between 1998 and 2016 in this race by examining changes of mean section velocity in 10km (Change A, i...

BACKGROUND: Existing evidence on whether marathon running contributes to hip and knee arthritis is inconclusive. Our aim was to describe hip and knee health in active marathon runners, including the prevalence of pain, arthritis, and arthroplasty, and associated risk factors. METHODS: A hip and knee health survey was distributed internationally to marathon runners. Active marathoners who completed ≥5 marathons and were currently running a minimum of 10 miles per week were included (n = 675)...

INTRODUCTION: As the popularity of ultramarathon participation increases, there still exists a lack of understanding of the unique psychological characteristics of ultramarathon runners. The current study sought to investigate some of the psychological and behavioral factors that are involved in ultramarathon running. METHODS: We obtained information from participants of the Bear Chase Trail Race via an online survey. This race is a single-day, multidistance race consisting of a 10 k, half marathon, 50 k, 50 mi, and 100 k run in Lakewood, Colorado, at a base altitude of 1680 m with total altitude in climbs ranging from 663 to 2591 m...

A specific subset of micro RNAs (miRs), including miR-133 and miR-206, is specifically expressed in muscle tissue, so that they are currently defined as muscular miRs (myomiRs). To further elucidate the role of myomiRs in muscle biology, we measured miR-133a and miR-206 in plasma of 28 middle-age recreational athletes. The study population consisted of 28 middle aged, recreation athletes (11 women and 17 men; mean age, 46 years) who completed a 21.1 km, half-marathon. The plasma concentration of miR-133a and miR-206, the serum concentration of creatine kinase (CK) and high-sensitivity (HS) cardiac troponin T (cTnT), as well as capillary lactate, were measured before and immediately after the run...
