When weight loss (WL) is necessary, athletes are advised to accomplish it gradually, at a rate of 0.5–1 kg/wk. However, possible that losing 0.5 kg/wk better than 1 in terms preserving lean body mass (LBM) and performance. The aim this study was compare changes composition, strength, power during weekly body-weight (BW) 0.7% slow reduction (SR) vs. 1.4% fast (FR). We hypothesized the faster WL regimen would result more detrimental effects on both LBM strength-related Twenty-four were...
Objective A periodic health evaluation (PHE) is a comprehensive and multidisciplinary investigation of athlete widely used in elite sport, but its contents benefits can be questioned. This study aimed to determine the prevalence conditions identified by PHE among Paralympic Olympic athletes over four consecutive Games cycles from Rio de Janeiro 2016 Beijing 2022 assess potential pitfalls programme detecting existing injuries, illnesses other issues. Methods We collected extensive history...
Background Various altitude training regimes, systematically used to improve oxygen carrying capacity and sports performance, have been associated with increased oxidative stress inflammation. We investigated whether intake of common antioxidant-rich foods attenuates these processes. Methods In a randomized controlled trial, 31 elite endurance athletes (23 ± 5 years), ingested (n = 16), (> doubling their usual intake), or eucaloric control 15) during 3-week camp (2320 m). Fasting blood urine...
To describe the illness and injury pattern of Norwegian Para athletes over five consecutive Paralympic Summer Winter Games cycles to identify which health problems should be targeted in risk management plans with respect impairment types.We monitored from 12 18 months prior each Game using a weekly online questionnaire (Oslo Sports Trauma Research Center-H2 (OSTRC-H2)). We asked them report all they had experienced preceding 7 days, irrespective their consequences on sports participation or...
High doses of isolated antioxidant supplements such as vitamin C and E have demonstrated the potential to blunt cellular adaptations training. It is, however, unknown whether intake high antioxidants from foods has similar effects. Hence, aim study was investigate antioxidant‐rich affects altitude training in elite athletes. In a randomized controlled trial, 31 national team endurance athletes (23 ± 5 years) ingested (n = 16) or eucaloric control 15) daily during 3‐week camp (2320 m)....
The present study explored the impact of pre-altitude serum (s)-ferritin and iron supplementation on changes in hemoglobin mass (ΔHbmass) following altitude training. Measures Hbmass s-ferritin from 107 sojourns (9-28 days at 1800-2500 m) with world-class endurance athletes (males n = 41, females 25) were analyzed together self-reported illness. Altitude a hypoxic dose [median (range)] 1169 (912) km·h increased (mean ± SD) 36 38 g (3.7 3.7%, p < 0.001) decreased -11 (190) µg·L-1 (p 0.001)....
Background: Altitude training stresses several physiological and metabolic processes alters the dietary needs of athletes. International Olympic Committee (IOC)'s Nutrition Expert Group suggests that athletes should increase intake energy, carbohydrate, iron, fluid antioxidant-rich foods while at altitude. Objective: We investigated whether adjust their according to IOC's altitude-specific recommendations, an in-between meal intervention with altered athletes' composition nutrition-related...
Background Low bone mineral density (BMD) increases the risk of stress injuries (BSI) and is one several clinical concerns in Para athlete sports medicine. However, whether microarchitecture altered athletes not known. Objective We aimed to investigate BMD, incidence Norwegian elite athletes. Design In this cross-sectional study athletes, Dual energy x-ray absorptiometry (iDXA, Lunar, GE Health Care) derived areal trabecular score (TBS), a surrogate marker for microarchitecture, body...
A 22- year old elite male skijumper seeked counseling for body weight regulation in 2003. He was struggling with and eventually diagnosed bulimia nervosa (BN) 2004. received both nutritional psychiatric became symptom free 2007. Between 2003-2007 he performing at a peak international level despite his disorder. From 2007 attached to our current nutrition team Norwegian Olympic Sports Center has medical follow-up. PURPOSE: Maintain good health, appropriate optimal performance. METHODS: Body...
