Impact of a 4-Week Intensified Endurance Training Intervention on Markers of Relative Energy Deficiency in Sport (RED-S) and Performance Among Well-T…
2020
Cyclists often apply block periodization to high training volumes in meso- and macrocycles to optimize training adaptation and to prepare for competition. Body mass influences performance in many sports, including endurance disciplines, and conditions related to the syndrome Relative Energy Deficiency in Sports (RED-S) such as metabolic adaptations and premature osteoporosis have also been reported in male cyclists. This study aimed to determine how a 4-week mesocycle of intensified endurance training designed to increase performance, would affect markers of RED-S in well-trained male cyclists. Twenty-two participants (age: 33.5 ± 6.6 years, height: 181.4 ± 5.2 cm, weight: 76.5 ± 7.4 kg, pe…
The Effect of a Ketogenic Low-Carbohydrate, High-Fat Diet on Aerobic Capacity and Exercise Performance in Endurance Athletes: A Systematic Review and…
2021
A low-carbohydrate, high-fat (LCHF) diet has been proposed to enhance the fat utilization of muscle and the aerobic capacity of endurance athletes, thereby improving their exercise performance. However, it remains uncertain how the macronutrient intake shift from carbohydrate to fat affects endurance exercise training and performance. This study performed a systematic review and meta-analysis to explore the effects of a ketogenic low-carbohydrate, high-fat (K-LCHF) diet on aerobic capacity and exercise performance among endurance athletes. Searches were carried out in five electronic databases, and we followed the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) gu…
Nutrition Knowledge Is Associated with Energy Availability and Carbohydrate Intake in Young Female Cross-Country Skiers
2021
The aim of this study was to provide information on energy availability (EA), macronutrient intake, nutritional periodization practices, and nutrition knowledge in young female cross-country skiers. A total of 19 skiers filled in weighted food and training logs before and during a training camp. Nutrition knowledge was assessed via a validated questionnaire. EA was optimal in 11% of athletes at home (mean 33.7 ± 9.6 kcal·kgFFM−1·d−1) and in 42% at camp (mean 40.3 ± 17.3 kcal·kgFFM−1·d−1). Most athletes (74%) failed to meet recommendations for carbohydrate intake at home (mean 5.0 ± 1.2 g·kg−1·d−1) and 63% failed to do so at camp (mean 7.1 ± 1.6 g·kg−1·d−1). The lower threshold of the pre-ex…
Er supermosjonisme sunt? : kartlegging av helsevariabler blant mannlige langdistanseløpere og syklister.
2016
Masteroppgave folkehelsevitenskap - Universitetet i Agder 2016 Introduction: Physical activity is well documented as an important factor for good health. There are however some people who train far beyond the national recommendations for 6 physical activity combined with work and family life. The research done on «high volume exercisers» is limited, specially the health variables. Objective: The purpose with this master paper is to investigate if high volume exercise is healthy. By identifying different health variable it may point to how the body responds to high training volume. Method: 41 male high volume exercises (18 to 50 years) were included in this cross-sectional study. The compila…
Spiser mosjonister og supermosjonister sunt? : En kartlegging av kostholdet til mannlige utholdenhetsmosjonister og supermosjonister
2017
Masteroppgave folkehelsevitenskap ME516 - Universitetet i Agder 2017 Background: To achieve the optimal recovery between workouts and best possible performance at training and in competitions, an optimal diet is essential for athletes at all levels. Previous studies have focused on the nutritional status of female athletes and few studies have researched the dietary habits and possible negative consequences of an insufficient diet in male athletes. Purpose: The main purpose of this study was to characterize the dietary intake of a group endurance-trained man and, on the basis of their physical fitness, compare their diets to the energy and nutrition recommendations developed by Helsedirekto…
Acute effects of fatigue to strength and power variables in edurance trained athletes
2015
The purpose of this bachelor thesis was to investigate how fatigue affects strength and power in endurance trained athletes. This thesis is written for the athletes, coaches and researchers in the field of sport. Total of 7 endurance athletes (age 23.3 years ± 1.3, height 174.7 cm ± 6.4, weight 66.5 kg ± 8.4) volunteered for the study, 4 male and 3 female. Hypotheses were that measured variables do not decrease after fatiguing protocol and that the potentiation may counteract fatigue. Fatigue was induced in a continuous maximal treadmill running, where speed was increased every five minutes by one km/h. When necessary, after 45 minutes of running, speed was increased every minute by one km/…
Prevalence of relative energy deficiency in sport among well-trained male Norwegian cyclists and long-distance runners
2016
Masteroppgave i idrettsvitenskap - Universitetet i Agder 2016 Introduction Relative Energy Deficiency in Sport (RED-S) links low and reduced energy availability (EA) with negative health and performance consequences, though not well investigated in male endurance athletes. The aim of this study was to investigate the prevalence of RED-S and associated health consequences in well-trained male endurance athletes. Methods Forty-one subjects, cyclists (n=21) and runners (n=20) [age: 40 (31-45) years; BMI: 23.5 (21.4-24.0) kg/m2; body-fat: 14.0% (10.0-16.5%); training volume: 12 (9-16) h/week presented as median + interquartile range] were recruited. Protocol included assessment of bone health, …
Acute HIT session induced changes and recovery in muscle activation level, voluntary force production and jump performance during 8 weeks of HIT trai…
2017
High-intensity interval training (HIT) has gained wide popularity among competitive athletes and sport enthusiasts in the recent decades. While an extensive amount of research has been done on acute neuromuscular (NM) response and recovery after low-moderate intensity endurance training, the data regarding HIT in recreational athletes remains to be limited. In order to reduce that gap, the present study investigated the acute HIT session induced changes and recovery in muscle activation level, voluntary force production and counter movement jump performance during 8 weeks of HIT training in recreationally endurance trained men. A total of 9 subjects age 30.7 years (± 5.8), participated in t…

Restitusjonsvaner hos unge toppidrettsutøvere i Sør-Norge : En kartleggingsstudie av utholdenhet- og ballspillutøvere
2018
Masteroppgave idrettsvitenskap ME517 - Universitetet i Agder 2018 Background: In order to perform optimally in training and competition, the recovery inbetween, through adequate diet and sufficient sleep/rest, is of great importance. Up until now, most studies have only featured adult athletes. Similarly, studies conducted on young athletes, as well as across sports, are limited. Purpose: The purpose of this study was to assess the habits of recovery, in terms of diet and sleep, with regards to the recommendations given by Helsedirektoratet and Olympiatoppen. Further investigating the use of different recovery strategies, among young elite athletes in southern Norway. Method: A total of 36 …
