Q

What is savouring?
- What is the findings in relation to + affect?
- Attributing Internal causes for + ve and - ve events?
- Implications?

A

Savouring: act of stepping outside of an experience to review and appreciate it

  • Savouring strategies that amplify positive emotions associated with greater frequency of +ve affect
  • Strategies people use to savour +ve experiences related to increased levels of daily mood and subjective wellbeing

Assigning positive events to internal, global, stable causes = decreased depression

Assigning negative events to internal, global, stable causes = increased depression

  • Implications: encourage enhancing amplifying savouring and diminishing dampening savouring

Q

Savouring study: Savouring chocolate
- What was found when participants were asked to eat chocolate with vs without savouring it?

A
  • One was instructed to savour chocolate by focusing on its taste, texture, and smell
  • Other group asked to eat it without any specific instructions

RESULTS: group who savoured chocolate reported higher levels of positive emotions and a more enjoyable experience compared to control group

Q

What is HEDONIC ADAPTATION?
- What does savouring and other techniques attempt to do in regards to this?

A

Getting used to / Adapting to the feelings of positive or negative emotions and returning to baseline

Savouring attempts to stop this adaptation so you feel good for longer

Q

What is flow?
- Define (characteristics)
- Requirement to reach flow?

A
  • Mental state in which you’re performing an activity where you are fully immersed, involved, where you feel energized, have a sense of control, strong sense of self, focused, and you’re enjoying it as you go
    => It’s like being in the zone.

Characteristics:
* Complete concentration on task
* A sense of ecstasy: of being outside everyday reality
* Great inner clarity: knowing what needs to be done, and how well we are doing it
* Knowing activity is doable
* A sense of serenity: no worries about oneself, and a feeling of growing beyond boundaries of ego
* Timelessness: thoroughly focused on present, hours seem to pass by in minutes
* Intrinsic motivation: whatever produces flow becomes its own reward

Requirement = A match between the CHALLENGE and YOUR SKILL LEVEL

Q

The research on flow
- What does it say?

A
  • Flow described in remarkably similar terms regardless of SES, age, culture and ethnicity
  • Teenagers identified as “high-flow” kids more likely to make it to University, have deeper social ties, and experience more success in life relative to “low-flow” teenagers
  • Suggests flow is a state that builds PSYCHOLOGICAL CAPITAL that can be drawn on for years to come
  • Better to choose activities that induce flow (read a book) over activity that only induce temporary pleasure (watching TV, shopping)
    => In long run, better to pursue gratification over pleasure
    => Cannot shortcut our way to happiness

Q

The vagus nerve and meditation
- What is it?
- Why is it important?

A
  • Vagus means wandering
  • Vagus nerve main component of parasympathetic nervous system – responsible for rest and relaxation
    => so activating it can help us relax and reduce anxiety
  • Its activity can be influenced by breathing practices (slow breathing)
  • Singing can also activate vagus nerve
  • Just taking a deep breath is a hack to reverse sympathetic nervous system activation

Q

Research on Meditation & Mindfulness

A
  • Multiple studies show benefits of meditation on positive emotions, stress, cognitive abilities, physical health, pain, sleep
  • Helps regulate stress response, lowers cortisol output, lowers blood pressure, reduces chronic inflammation and maintains a healthy microbiome
  • Increases grey matter concentration over 8 wks
  • Meditators inspire efforts to solve complex problems like climate change
  • 8 weeks training increased activity in left-prefrontal cortex, relative to right side
  • This pattern associated with happy individuals
  • Also showed stronger immune response to influenza vaccine
  • Mindfulness introduced into schools showed those who engaged in mindfulness 3X/day became more optimistic and had better emotional and social competencies

Meta analysis of Meditation:
- Small effects but generally equivalent to other treatments (not better than active controls)
- Insufficient evidence in some areas but hampered by small sample sizes

Q

Meditation: RAIN Method
- What is it?

A

The RAIN method to help deal with negative emotions

  1. Recognize what is happening
  2. Allow feeling to be just as it is – just let negative emotions be
  3. Investigate emotions with interest and care
  4. Nurture with self-compassion
  • Research shows this acceptance significantly reduces anxiety and depression

Q

Mind wandering
- What is it?
- Is it good or bad?
- effects on well-being?

A
  • We do it a lot – in fact, about 50% of time! (BAD)
  • Sadly associated with lower ratings of happiness
    => Suggests need to tighten that mind focus through meditation
  • Deactivates default network and strengthens synapses through paying attention as it increases state of autonomic arousal, increasing firing
    => cells that fire together, wire together
  • Meditation shown to increase positive emotions over time

Q

Study: Relaxation training’s effect on healthcare resource utilization

  • Compared people who had taken Relaxation Response Resiliency Program (3RP; n=4452) and controls (n=13149) over 1 year
  • findings?
A
  • Intervention group’s Emergency department (ED) visits decreased from 3.6 to 1.7/year and Hospital and Urgent care visits converged with controls (controls were healthy)
  • Subgroup analysis showed intervention group significantly reduced utilization relative to controls

BASICALLY IT REDUCES HOSPITAL VISITS IN SICK PEOPLE AND CAN HELP SAVE MONEY

Q

How might meditation work?

A
  • Amps up brain’s BDNF (Brain Derived Neurotrophic factor)
  • Meditation leads to less activation of default mode network (responsible for mind wandering)
  • By reinforcing areas associated with staying focused and present, helps reprogram brains for wellbeing, empathy and gratitude
  • Changes in functional connectivity can be seen after only 3 days of mindfulness practice
  • Growth of new brain cells in hippocampi
  • Can also increase sense of social connectedness
  • Better regulation of parasympathetic nervous system
  • Improvements in immune function
  • Increased telomerase activity (bits on the end of chromosomes)

Q

Yoga

A
  • Combination of muscular activity & internally directed mindful focus on awareness of self, breath, & energy
  • Word “yoga” comes from a Sanskrit root “yuj” which means union, or yoke, to join, and to direct and concentrate one’s attention
  • Regular practice of yoga promotes strength, improved cognition, better sleep, quality of life, endurance, flexibility and facilitates characteristics of friendliness, compassion, and greater self-control, while cultivating a sense of calmness and wellbeing
  • Sustained practice also leads to changes in life perspective, self-awareness and an improved sense of energy to live life fully and with genuine enjoyment
  • Practice of yoga produces a physiological state opposite to that of flight-or-fight stress response
  • Yoga encourages one to relax, slow breath and focus on present, shifting

Q

Definitions of wellbeing:
- scientific definition and WHO definition

A

What is wellbeing?
Combination of feeling good and functioning well; experience of positive emotions like
happiness and contentment, development of one’s potential, some control over one’s life, sense of purpose, experiencing positive relationships.

World Health Organization
defines positive mental health “A state of wellbeing in which the individual realizes their own abilities, can cope with normal stresses of life, can work productively and fruitfully, is able to make a contribution to their community”

Areas of the world associated with the greatest longevity

17
Q

Sit and Rise Test (SRT)
- What is it?
- Study Findings?

A

Prognostic test

Being able to sit on a spot and stand up again without using your hands

Study: Brazilian researchers studied 2000 people (aged 50 - 80 years) over 6.5 years
- Every time came into clinic they made them sit
- Marked on a 10 point scale: 5 points for sitting & 5 points for standing

Results: Every point +/- = 21% change in longevity & quality of life

  • Scoring 0-3 were 6.5 times more likely to die during 6-year study than those scoring 8 10
  • If scored 3.5 to 5.5 were 3.8 times more likely to die
  • If scored 6 to 7.5 were 1.8 times more likely to die
18
Q

Grip Strength
- Findings?

A

Prognostic test

Hand grip, measures muscular strength, which decreases as you age,
AND
has been shown to be better than blood pressure in predicting mortality and morbidity.

Study findings:
Measuring grip strength may identify patients with major illnesses (heart failure / stoke) who are at high risk of dying from their illness.”

  • For every 5-kg decline in grip strength, there was a 1 in 6 increased risk of death from any cause.
  • Researchers now trying to improve low muscle strength to increase patients life expectancy.

“muscle weakness is the new smoking”:
Grip strength is inversely associated with DNA methylation age acceleration (aging of DNA)

19
Q

Define A prognostic test

A

A prognostic test gives an advance indication of a future event.

20
Q

Hans Selye’s 3 stages of Stress and Exercise

A

(1) Alarm, the Initial stress response

(2) Resistance development, builds reserves/functional capacity to cope with frequent stress

(3) Exhaustion, when stress is intolerable – acute or chronic

Periodised programme to avoid exhaustion and maximise performance

21
Q

What is the best program to maximise performance and avoid exhaustion?

A

Periodised programme to avoid exhaustion and maximise performance
- progressive overload

22
Q

Milo and the Story of Strength

A

Carried a baby Cow / Ox until it was fully grown (progressive overload)

23
Q

Training Principles - Define:
- Overload
- Progression
- Adaptation
- Reversibility
- Variation
- Overtraining

A

Overload: For the body’s systems to adapt they must be overloaded. Just taking part in an activity will not necessarily result in any improvements in fitness, as the body will not be stressed to a greater extent than normal.

Progression: Overload imposed on an athlete must be progressive. If a training programme stays at the same intensity for too long, adaptations will only be evident at the beginning, after this the body is no longer overloaded.

Adaptation: The way the body responds to the training stimulus. Parts of the body that are actively stressed adapt to those stresses, leading to an increase in performance.
- Example, muscle strength and tone increased following resistance training.

Reversibility: Adaptations as a result of training are all reversible.
“If You Don’t Use It, You Lose It”
- Adaptations to endurance training can be lost more quickly than it takes to achieve
them. Strength gains are lost more slowly
We quickly adapt to exercise by increasing fitness.
We quickly adapt to less exercise by losing fitness.
Takes only 3-4 weeks for our bodies to get out of condition
If muscles are not used they ATROPHY – waste away!!

Variation: Using a variety of different training methods we will keep our enthusiasm and motivation. We can avoid tedium (boredom) by:
- follow long work out with short one,
- hard session with more relaxed one,
- vary where and when we train,
- can avoid overuse injuries by varying the way we train

Overtraining: Overtraining results in poorer performances and training levels.
- Increases the risk of injury and illness and decreases the dire to exercise.
- Over-reaching is the stage before overtraining
Signs of overtraining:
- Inability to concentrate, Lack of flow
- Loss of skills
- Reduced powers in strength
- Greater recovery time needed.

24
Q

Is Exercise Always Beneficial?

A

NO, you can have too much which can also result in heart disease or other health outcomes.

Proposed U Shaped relationship between Physical Activity and Heart Disease.

Study findings:
Chronic traumatic encephalopathy (CTE) found in more than 91% of former NFL players (345 of 376) involved in an ongoing study on the degenerative brain disorder.

25
Q

Smallest Beneficial Dose?
- Frequency?
- Duration?
- Intensity?
- Endurance, V̇O2max, Strength, or Muscle Size?

A

Frequency:
- More exercise is required to increase VO2max, than that required to maintain it
- Possible to maintain the increased VO2max for at least 15 wk by training at high intensity for 2 d/wk or 4 d/wk

Duration:
- When duration was dropped by ⅓ (to 26 min) or ⅔ (13 min) VO2max gains were mostly preserved for 15 weeks.
- SHORT endurance preserved in both 13min and 26 min sessions.
- Long endurance was WORSE for the 13 min group.

Intensity:
CAN GET AWAY WITH:
- TRAINING LESS OFTEN (FREQUENCY), OR SHORTER DURATION,
- BUT NOT WITH GOING EASY. (INTENSITY MUST BE MAINTAIN)

26
Q

Minimum Dose Training Review Study Conclusions
For:
- General population
- Younger population
- Older population

Key variable in all this?

A

General populations:
- Endurance performance can be maintained for up to 15 weeks when training frequency reduced to 2 sessions per week or when volume is reduced by 33–66% (as low as 13–26 minutes per session), as long as exercise intensity (exercising HR) is maintained.

Strength and muscle size (at least in younger populations):
- Can be maintained for up to 32 weeks with as little as 1 session of strength training per week and 1 set per exercise, as long as exercise intensity (relative load) is maintained.

Older populations:
- Maintaining muscle size may require up to 2 sessions per week and 2–3 sets per exercise, while maintaining exercise intensity.

Exercise intensity seems to be the key variable for maintaining physical performance over time, despite relatively large reductions in exercise frequency and volume.

27
Q

Activity Guidelines - WHO

A
  • At least 150 - 300 mins moderate intensity aerobic activity per week

OR

  • 75 - 150 mins vigorous-intensity aerobic (or combination of the 2)
  • Strength training of all major muscle groups 2x / week - gives additional health benefits
  • Limit sedentary time
  • Aim for more than minimum levels of moderate-to-vigorous intensity physical activity
28
Q

Activity Guidelines - ACSM
- Define Sedentary behavior
- Define Sedentary lifestyle

A

Sedentary behavior: is defined as any waking behavior characterized by the expenditure of 1.5 METs or less of energy while in a sitting, reclining, or lying posture

Sedentary lifestyle: not participating in at least 30 minutes of moderate-intensity physical activity on at least 3 days/week for at least 3 months

29
Q

VO2Max
- Changes with age?
- What is it a predictor for?

A

After 30 years of age, VO2max progressively decreases with age at a rate of about 10% per decade.

Having a higher VO2 is linked to a better quality of life with less dependence on others

30
Q

How might Exercise Improve Learning?
- What chemical is involved?
- Where is it found?
- how does it exert its effects?

A

Brain derived neurotrophic factor (BDNF) protein found in high concentrations in the central nervous system (CNS)

BDNF has a role in development, differentiation and survival of neurons all factors that aid learning.

Circulating BDNF is divided into 2 components:
1 - Plasma.
- Can freely circulate and cross the blood-brain barrier in both directions.

2 - Serum.
- Both bound to platelets and freely circulating in the blood.
- 99% of serum BDNF stored in platelets - which contain 100 - 200 times more BDNF than plasma.

BDNF can be released when under physiological stress (including exercise).

Although most BDNF comes from the brain, muscle contraction increases its circulatory concentration. During physical activity, the serum portion of BDNF stored in platelets may be released into the plasma, making it free to cross the blood brain barrier

Brain is the primary source of circulating BDNF at rest and during exercise, peripheral
tissues also produce this protein, which makes it difficult to understand which region
causes changes in free BDNF concentrations

31
Q

What is the maximum amount of time we should be spending Sedentary to still receive the benefits of Brain derived neurotrophic factor (BDNF)?

A

Spend < 8.5 hours a day Sedentary to achieve the benefits of cardiovascular fitness in BDNF

32
Q

The Runner’s (Persistence) High
- What chemical is involved?
- What does it do?
- Can we get it through other activities?

A
  • A long run greatly increases levels of endocannabinoids in our brain.
  • Endocannabinoids lessen pain, boost mood, trigger other feel-good chemicals and neurotransmitters (dopamine and endorphins).
  • Endocannabinoids help protect us against anxiety and depression.

Runners high is not limited to running - it can appear after all sorts of exercise that
takes more than 20mins - Swimming, Cycling, Speed walking. Some have termed the
runners high - a “persistence high’

33
Q

Can you get addicted to exercise? (vs drugs)
- how long until you can make a habit of exercise?

A
  • Exercise addiction is an unhealthy obsession with physical fitness and exercise.
  • Exercise activates our brain’s reward system- stimulates the release of feel-good chemicals (endocannabinoids, dopamine, endorphins and noradrenaline) so regular physical activity can be addictive.
  • Drugs are easier to get addicted to, over time lessen our sensitivity and the more drugs you do the worse you feel about it.
  • Changes in our brain due to regular exercise are less intense than drugs and happen more slowly.

Exercise increases receptors for endocannabinoids. Exercise makes dopamine cells more responsive. The more exercise you do the better you feel about it.

  • Human studies show that exercising 4x week for 6 weeks results on getting hooked on exercise.
