Current Predictive Resting Metabolic Rate Equations Are Not Sufficient to Determine Proper Resting Energy Expenditure in Olympic Young Adult National…
2021
Predictive resting metabolic rate (RMR) equations are widely used to determine athletes’ resting energy expenditure (REE). However, it remains unclear whether these predictive RMR equations accurately predict REE in the athletic populations. The purpose of the study was to compare 12 prediction equations (Harris-Benedict, Mifflin, Schofield, Cunningham, Owen, Liu’s, De Lorenzo) with measured RMR in Turkish national team athletes and sedentary controls. A total of 97 participants, 49 athletes (24 females, 25 males), and 48 sedentary (28 females, 20 males), were recruited from Turkey National Olympic Teams at the Ministry of Youth and Sports. RMR was measured using a Fitmate GS (Cosmed, Italy…
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…
Muskelfunksjon blant unge toppidrettsutøvere i Sør-Norge : Finnes det en sammenheng mellom utvalgte fysiologiske faktorer og muskelstyrke, power og h…

Masteroppgave idrettsvitenskap ME517 - Universitetet i Agder 2019 Background: Muscle strengthand poweris a determining feature of performance in many different sports and thephysiologicalfactors that affect muscle functionare many. Previous studies have mostly concernedadult athletes, while researchfeaturing young elite athletes or differences between sports have been scarce. Purpose: The study’s purposeis to investigate possibleconnectionsbetween physiological factors such as resting metabolic rate, protein intake, and fat-free mass and muscle functionamong young elite athletes in southern Norway.Differences between sport-groupswere alsoinvestigated. Method: A total of 36young elite athlet…
Resting energy expenditure and body composition in morbidly obese, obese and control subjects
1994
Resting energy expenditure (REE) was investigated by indirect calorimetry in relation to body composition and to different degrees of obesity in order to assess if a defective energy expenditure contributes to extra body fat accumulation. Differences were found between control subjects (group C; BMI 23 +/- 0.5 kg/m2, REE 5890 +/- 218 kJ/day; mean +/- SEM) and obese subjects (group O; BMI 34.2 +/- 0.9 kg/m2, REE 7447 +/- 360 kJ/day; P0.0001) and between group C and morbidly obese subjects (group MO; BMI 49.9 +/- 1.6 kg/m2, REE 8330 +/- 360 kJ/day; P0.0001); REE was not significantly different between groups O and MO. Body composition data were obtained by means of body impedance analysis. Ev…
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, …
Uztura paradumu, fiziskās aktivitātes un miera vielmaiņas intensitātes izvērtējums jaunu cilvēku grupā
2016
Liekais svars un aptaukošanās pazemina dzīves kvalitāti un ir par iemeslu daudzām saslimšanām: diabētam, koronārajām sirds slimībām, onkoloģiskajām saslimšanām, metabolajam sindromam. Pētījuma mērķis ir izvērtēt uztura, fiziskās aktivitātes (FA) un miera vielmaiņas intensitātes (RMR) korelāciju ar ķermeņa tauku masu jaunu, pieaugušu, klīniski veselu cilvēku grupā. Pētījuma gaitā tika analizēta izmeklējamo personu 3 dienu uztura dienasgrāmata, fiziskā aktivitāte noteikta ar anketēšanas metodi, veikti antropometriskie mērījumi un reģistrēta miera vielmaiņas intensitāte ar netiešās kalorimetrijas metodi. Pētījuma rezultātā tika secināts, ka respondentu uzturā ir samazināts relatīvais ogļhidrāt…
