Lecture 8 - REDS Flashcards
when you are working with the athlete or general population you need to think about more than …
you need to think about more than just the nutrients
what is an eating disorder
clinically diagnosable
eating disorders are higher in sports that ..
involve weight classes
aesthetic sports
where having a low body mass is seen as advantageous
what is energy availability
amount of energy available following the energy used for exercise for normal physiological functions per kg of fat free mass
what is the energy availability equation
energy availability = energy intake - exercise energy expenditure / fat free mass
there is evidence that low energy availability in females can ..
impair reproductive hormones
impact bone health
in females a negative energy balance affects what and this leads to low bone density
lowers oestrogen
high energy deficiency can lead to
functional hypothalamic amenorrhea
what is RED’s
Relative Energy Deficiency in Sport
symptoms of relative energy deficiency in females
- impaired menstrual cycle
- impaired immune system
- impaired bone density
- reduced female hormones
what are the effects of relative energy deficiency in male athletes
- decreased hormone levels
- decreased protein synthesis
- direct impact on bone metabolism
a survey found there was increased risk of low energy intake for athletes participating in what type of sport
individual sport
a survey found irregular periods to be associated with what
history of stress fracture
how do errors occur with expenditure when calculating energy availability
- under or over reporting
- what counts as exercise
- representative ?
how do errors occur with intakes when calculating energy availability
- under or over reporting
- burden
- representative ?
what is the LEAF questionnaire
a screening tool for the identification of female athletes at risk for the female triad
what is the female triad
shows how low energy availability is linked to low oestrogen and bone mineral density
what are the factors of the LEAF
menstrual function
gastrointestinal function
injuries
reasons for LEA or REDS can be …. or …
intentional or unintentional
what is a quick fix diet
energy content and the meals / nutrients are similar day to day = means it is a bad meal plan
a study on elite rugby players found that those who had the worst body image also had the lowest
lowest energy availability
what are the 5 reasons as to why you might measure body composition
- identify physical characteristics of elite performers
- assess and monitor growth
- monitor training programs / dietary interventions
- determine optimal body composition for weight category sports
- monitor the relationship to health and performance
considerations for body composition testing
be aware or vulnerable athletes
focus on performance
treat data confidently
de-emphasise the importance of body composition
questions for someone that has cut out food groups from their diet and has low energy intake
- menstrual history
- potential food intolerances
- food groups avoided
- lifestyle
- gut health
- stress
how could an athlete be impacted from their parents eating habbits
parents may be trying to cut down their intake, the athlete will have much higher requirements compared to them so this could make the child at risk of low energy intake
what aspect of recovery will take the longest from REDs
bone mineral density
