Q

What are the 5 defined sleep stages, including the waking state

A
  1. Stage W (waking state); The EEG contains alpha activity
  2. Sleep stage N1; characterized by a relatively low-amplitude, mixed-frequency EEG often accompanied by slow, rolling eye movements (SEM = slow eye movements). Decreasing muscle tone.
    —> also called drowsiness, transition between wakefulness and sleep
  3. ** Sleep stage N2**; characterized by sleep spindles and K-complexes on the background of relatively low-amplitude mixed-frequency EEG activity.
    —> accounts for the largest percentage of the night; stable sleep
  4. ** Sleep stage N3 (deep sleep)**; characterized by slow-wave activity (SWS = slow-wave sleep or delta waves) of 0.5–2 Hz and an amplitude greater than 75 μV in the frontal EEG lead.
    —> muscles are deeply relaxed and heart/breathing rate are slow; dominant in the first half of the night
  5. ** Sleep stage R**; characterized by a relatively low-amplitude mixed-frequency EEG in combina- tion with episodically occurring rapid eye move- ments (REM = rapid eye movement) and a low-amplitude EMG.
    —> completely paralyzed muscles; dominant in the second half of the night

Q

What are 3 ways to measure sleep in the laboratory/field

A
  1. Polysomnography; sleep is measured by three physiological parameters: brain waves, eye move- ments and muscle tone. These parameters are recorded by electroencephalography (EEG), electrooculogram (EOG) and electromyography (EMG). Over one night, this standard recording reveals cyclic changes in the physiological parameters. Based on these variations, sleep can be divided into different stages.
  2. Actigraphy; The activity monitor is a small accelerometer that is sensitive to movement direc- tion and intensity. The basic idea of actigraphy is that movement is correlated with alertness, and long periods of inactivity are correlated with sleep. Activity monitors (often worn on the non-dominant wrist) have the advantage that they are suitable for field studies because they are easy to use for participants. However, they are limited because they can- not really distinguish between sleep (or even different sleep stages) and alertness.

Q

explain how training times, morning and evening types, training forms, overtraining, naps and nutrition influence sleep

A
  • training times; early training sessions lead to shorter than recommended sleeping time
  • morning and evening types; people who prefer early mornings tend to do sports that require training in the morning and same for evenings
  • training forms; intensive intermittent exercise results in a higher recovery requirement than strength training, and therefore increased sleep time
  • overtraining; sleep efficiency is significantly reduced in the transition from symptoms of overuse to overtraining, often interpreted to mean that sleep disorders occur in parallel with overtraining
  • naps; naps seem to be a suitable method for athletes to reduce sleep debt, can be beneficial in learning skills, strategies or tactics
  • nutrition; nutritional behavior can also have an influence on sleep. For example, carbohydrates that can be quickly absorbed by the body seem to be more supportive of sleep if they are taken about an hour before going to bed. On the other hand, high amounts of fat seem to reduce the total sleeping time.

Q

explain four points about the relation between sleep and competitions

A
  • sleep was reported to be worse before competitions, but there are no differences comparing sleep quality scores
  • there was a correlation between anxiety before a competition and how recovered athletes felt after sleep
  • multiple-day competitions with varying starting times can have a negative effect on quality and duration of sleep
  • stressful situations, such as competitions, might alter the dream content of athletes and consequently evoke disturbed dreaming

Q

what are 6 recommendations for sleep promoting activities

A
  1. Establish a bedtime routine:
    - rituals and/or repetitive behaviors associated with sleep to prepare body and mind for the night
    - relaxation or stress management strategies to reduce cognitive and emotional arousal
  2. Develop a positive mindset towards sleep:
    - challenge irrational attitudes and beliefs about sleep
    - accept occasional occurrences of sleeplessness and unrestful sleep
  3. Limit use of electronic devices before bedtime:
    - avoid emission of blue light which suppresses melatonin release (inhibiting sleepiness)
    - reduce activities that may cause cognitive and/or emotional arousal
  4. Sleep extension:
    - extended sleep periods may enhance performance and mood
    - must be aligned with the schedule
    - beneficial as long as sufficient drive to sleep at night is generated
  5. Daytime naps:
    - to reduce acute sleepiness
    - must be aligned with appropriate time of the day and schedule
    - establish individual optimal duration (ideally avoiding deep sleep and REM sleep for short-term recovery)
  6. Sleep hygiene recommendations:
    - arrange the bedroom dark, quiet, and cool
    - avoid alcohol, caffeine and stimulating beverages before bedtime
    - reduce cognitive and physical strain before bedtime

Q

explain different aspects of recovery

A
  • regeneration = on the micro level, recovery is achieved through physiological processes that take place to restore the hormonal, cellular and fluid balance, among others, to undo the fatigue or damage which is induced by training and competition
  • immediate recovery = takes place between rapid, time-proximal finite efforts
  • short-term recovery = recovery between training sets, with different work-to-rest ratios that are suggested
  • training/competition recovery = the time between separate sessions or bouts

Q

explain the difference between functional overreaching and non-functional overreaching

A

Training is a process of overload that is deliberately used to disturb homoeostasis, which causes acute fatigue and eventually leads to an improvement in performance
after recovery. Thus, short-term decrements in performance are intentionally anticipated in terms of functional overreaching to achieve the effect of supercompensation. An imbalance between training load and recovery will lead to non-functional overreaching, where the first signs of psychological and hormonal disturbances will occur.

Q

explain overtraining syndrome

A

Overtraining as a verb indicates a process of intensified training with possible outcomes of short-term (functional) overreaching, non-functional overreaching or overtraining syndrome. “By using the expression ‘syndrome’, we emphasize the multifactorial aetiology and acknowledge that exercise (training) is not necessarily the sole causative factor of the syndrome”

Q

what are 4 interventions that can be taught to someone showing signs of overreaching/overtraining syndrome

A
  • recovery-stress monitoring; engage consciously in a mood-repair mode in which he would deliberately choose activities, music and readings with a mood-­enhancing impact
  • activities outside the sport
  • increase awareness of training intensity and recovery aspects
  • autogenic training to support the re-establishment of his emotional balance and enhance his recovery capacity

Q

explain recovery management in sport

A
  • recovery can be realized through either terminating or reducing stress or through change of activities
  • recovery strategies should always be implemented purposefully and in accordance with the individual’s preferences
  • self-monitoring is important, as insufficient knowledge on recovery and/or individually inadequate recovery activities as well as insufficient self-regulation are major contributors to underrecovery
  • self-control is needed to initiate appropriate recovery strategies, which even may be effortful and require additional resources

18
Q

explain chronic recovery and acute recovery

A

Withholding recovery at certain times (most commonly in preparation phase) serves to maximize adaptation to training in the long-term (chronic recovery). In terms of acute recovery, increased recovery should be used to decrease acute fatigue during the competition phase or to prepare for certain training sessions.

19
Q

what are 4 kinds of recovery and give some examples

A
  1. Regeneration and physical recovery: adequate sleep, rehydration, nutrition, cold-water immersion, cool-­ down, stretching, foam rolling
  2. Cognitive/mental recovery: breathing techniques, power napping, imagery, relaxation techniques
  3. Emotional recovery: mindfulness-based practice, debriefing, expressive writing
  4. Social recovery: enjoyable activities with family and friends
20
Q

explain rest

A

typically taken to mean a reduction or cessation of training and competition activities; a “method” for achieving recovery, is a “passive” rather than “active” recovery method (e.g. cool-down jogging) and is “characterized by inactivity”, where “inactivity” is implicitly considered as physical inactivity

21
Q

explain psychological detachment

A

recovery experience that involves stopping thinking about stressful elements of sport when away from sport, thoughts that would otherwise lead to strain, which comprises deleterious physiological and psychological symptoms
–> psychological detachment was significantly positively related to mental energy and significantly negatively related to incidence of injury (has a role in recovery)

22
Q

explain rest and its relation to acquiring movement skills

A
  • distributed practice, which involves practice sessions separated by rest periods of seconds to days, results in better learning than massed practice, which involves little or no rest between practice sessions
    –> gives time for consolidation of the memory of the task, which improves movement skill
  • learning is greater when practice is followed immediately by a rest period that is quiet and relaxing than when it is followed by engagement in mentally effortful tasks
    –> quiescent effect; effortful tasks disrupt memory consolidation, resulting in a poorer memory
23
Q

explain rest in relation to the development of expert sport performance

A

The development of expertise depends on years of daily engagement in only a few hours of maximum-quality
deliberate practice followed by many hours of resting.

24
Q

explain the Eccles-Kazmier Model of the Psychology of Rest in Athletes (EKMPRA)

A

The model distinguishes between two key concepts:
1. rest level; the extent to which an athlete currently feels rested
2.process of resting; athletes conceive of feeling rested as involving a physical aspect and a mental aspect
–> primary focus on the mental aspect
Compared to poorly rested athletes, rested athletes feel fresh, they value their sport, feel more motivated and apply more effort.
An athlete’s level of mental rest is increased via engagement in a process of resting, which encompasses (a) sleep and (b) resting while awake. Wakeful resting comprises six psychological experiences, called resting experiences.

25
Q

what are the 6 resting experiences

A

Resting experience 1: Getting a break from always thinking about one’s sport
- focus on subject unrelated to one’s sport
- avoiding cues that remind one of the sport

Resting experience 2: Getting a break from any kind of effortful thinking
- low-demand activities/physical environments/social environments
Resting experience 3: Getting a break from feeling life is controlled by one’s sport
- planning ahead to create “me time”
Resting experience 4: Getting a break from the monotony of the daily routine
- switching up normal routine
Resting experience 5: Being able to catch up on important work tasks
- scheduling time and protecting it
Resting experience 6: Being able to have a personal life outside of one’s sport
- scheduling time and protecting it

26
Q

what are 5 reasons why rest has been overlooked

A
  • There is a natural tendency to focus on action over
    inaction.
  • Competition outcomes (e.g. goals) apparent as
    direct consequences of physical actions.
  • Rest occurs covertly, making it challenging to
    research.
  • Rest is considered as simple and self-explanatory.
  • Rest is undervalued at cultural and societal levels
27
Q

what are 5 principles for consideration on rest and recovery

A
  1. Recovery does not just involve recovering physically; it involves recovering mentally.
  2. Providing physical rest days (i.e. a break from physical training) does not guarantee athletes the mental rest they need (e.g. stopping thinking about sport).
  3. Athletes can achieve the mental rest they need if they have the time, and can obtain the social and physical environmental conditions, required for high-quality (a) sleep and (b) wakeful resting. 4. High-quality wakeful resting involves specific resting experiences.
28
Q

explain the difference between micro- and macro-level recovery

A

micro-level recovery = involves athletes’ rejuvenation amidst actual training and competitive situations
macro-level recovery = regeneration after training or competitions during non-sport time

29
Q

explain the supercompensation principle

A

= the body, after adequate recovery, adjusts to be able to deal with higher demands

30
Q

explain **staleness*

A

Failure of the body to adapt to training which results in a temporary plateau (= a precursor to burnout)

31
Q

explain the 3 dimensions of burnout

A
  1. ** Emotional Exhaustion; Feeling emotionally worn-out and drained
    –> feeling empty/deflated and a lack of energy
    2.
    Devaluation/Depersonalisation**; Loss of interest and resentment
    –> not wanting to play anymore
  2. Reduced Accomplishment; Achieving below expectations and not meeting personal targets
    –> not having confidence in your own abilities
32
Q

how many athletes suffer from burnout (average)

A

10 %

33
Q

what are 6 negative impacts of burnout

A
  • Performance decrements
  • Decreased motivation
  • Troubled social relations that negatively impact team climate
  • Health issues
  • Mental (anxiety, eating disorders)
  • Physical (illness susceptibility, substance abuse)
34
Q

what are 6 factors associated with burnout

A
  • Overtraining/staleness
  • Early specialization (longer seasons, training)
  • Personality
  • Motivation
  • Coach behaviour
  • Social and logistical issues (travel grind, time)
35
Q

what are 10 physiological and psychological symptoms of burnout

A
  1. Increased resting and exercise heart rate
  2. Increased blood pressure and cortisol
  3. Increased muscle soreness and chronic muscle fatigue
  4. Increased sleep disturbances
  5. Increased colds and respiratory infections
  6. Increased mood disturbance
  7. Decreased appetite
  8. Decreased self-esteem
  9. Frustration
  10. Negative change in the quality of personal interaction with others (cynicism, lack of empathy)
36
Q

what are 2 different causes of burnout

A
  1. A reaction to chronic stress; explained within overtraining and psychosocial stress perspectives
    2) A motivational phenomenon; examined within self-determination and entrapment frameworks
37
Q

provide a model of burnout as a reaction to chronic stress

A

Smith’s Cognitive-Affective Model of Stress and Burnout = four stages of the stress process are paralleled
by the four stages of the burnout process. In the final stage of the burnout process, coping resources are insufficient to counteract cognitive overload and negative physiological responses associated with stress.
–> burnout is likely to occur when there’s an imbalance between sport demands and ability to meet them
–> Beyond lowering sport-based demands, increasing resources can be effective in deterring athlete burnout

38
Q

provide two models of burnout as a motivational phenomenon

A
  1. Investment Model of Burnout = continued sport participation is based upon an evaluation of rewards, costs,
    satisfaction, investment, and alternatives
    –> burnout occurs when the athlete perceives that the costs of commitment are greater than rewards
    Commitment may be based upon enjoyment or perceived entrapment:
    - If commitment is based upon enjoyment, the rewards outweigh the costs and the pursuit is worth it
    - If commitment is based upon entrapment, it is only a matter of time before burnout occurs
  2. Empowerment Model of Burnout = burnout is a social and organizational problem caused by an overly
    controlling and constraining social structure

Model:
- Desire to develop
identity separate from
sport not realized
and;
- Desire to feel personal
control over life’s
decisions not realized
leads to;
- Burnout
which leads to;
- Withdrawal from Sport

39
Q

what are 6 correlated of coach burnout

A
  • Perceived stress (+)
  • Social support (-)
  • Commitment (-)
  • Age (-)
  • Coaching issues (+)
  • Role conflict (+)
40
Q

what are 4 guidelines to prevent overtraining/burnout

A
  1. Keep workouts interesting, with age-appropriate games and training, to keep practice fun
  2. Take time off from organized or structured sports participation 1-2 days per week to allow the body to rest or participate in other activities
  3. Permit longer scheduled breaks from training and competition every 2 to 3 months while focusing on other activities and cross-training to prevent loss of skill or level of conditioning
  4. Focus on wellness and teaching athletes to be in tune with their bodies for cues to slow down or alter their training methodsprovide 4 guidelines to prevent overtraining/burnout
41
Q

explain detachment

A

Recharging batteries by ‘switching off’ from sport-related matters
- Shaking off physical exertion (physical detachment)
- Focus thoughts on things other than sport (cognitive detachment)
- Put aside sport-related negative emotions (emotional detachment)
–> Provides a ‘break’ of mental (and physiological) activation

42
Q

explain why it is important for coaches to recover as well

A
  • Coach well-being important predictor of interpersonal style
  • Negative influence stress/fatigue on athletes’ training experiences
  • Less instruction and social support
  • Reduced confidence and increased perceived pressure
  • A lack of recovery is linked to high stress levels and poor health of elite coaches
  • Coaches experience difficulties in distancing themselves from their work
43
Q

what are 2 forms of sleep deprivation and how does it affects performance

A
  • Total sleep deprivation (sustained wakefulness > 24-h)
  • Partial sleep deprivation (resricted sleep < 6 h)

Sleep deprivation affects performance through reduced:
* Focus and vigilance
* Determination, processing, and logical thinking
–> Both total and partial sleep deprivation have been shown to compromise the transmission speed of impulses from the brain to muscles
