3. • FATIGUE
Is defined as an:-
• "A multi-dimensional phenomenon in which the biophysiological,
cognitive, motivational emotional and physical state of the body is
affected resulting in significant impairment of the individual's ability to
function in their normal capacity“
It is described as:-
• a state of tiredness (which is not sleepiness) or exhaustion. Difficulty or
inability in initiating activity( perception of generalized weakness)
reduced capacity maintaining activity and difficulty with concentration,
memory and emotional stability

6. Mental- Mental fatigue is a temporary inability to maintain optimal cognitive
performance. The onset of mental fatigue during any cognitive activity is gradual, and
depends upon an individual's cognitive ability, and also upon other factors, such as
sleep deprivation and overall health.
A loss of energy may be related to mental health problems such as:_
• Depression
• Anxiety
• Grief
These conditions exhaust the body physically and emotionally and cause severe fatigue
to set in.
NEUROLOGICAL FATIGUE- People with Multiple sclerosis experience a form of
overwhelming tiredness that can occur at any time of the day, for any duration, and
that does not necessarily recur in a recognizable pattern for any given patient,
referred to as "neurological fatigue”.

7. CAUSES
1) MEDICAL
There are numerous potential causes of fatigue. For the majority of medical illness, fatigue is a
possible symptom.
• The medical causes of fatigue can be classified under broad disease categories. Some of
these disease categories include:
• Metabolic/Endocrine: Conditions such as anemia, diabetes, hormonal imbalances, or liver
or kidney disease
• Infections: Influenza, tuberculosis, or malaria
• Cardiac (heart) and pulmonary (lungs): Congestive heart failure, chronic obstructive
pulmonary disease (COPD), arrhythmias, and asthma
• Sleep problems: Sleep apnea, insomnia, and restless leg syndrome
• Vitamin deficiencies: Vitamin D deficiency, vitamin B12 deficiency, or iron deficiency
• Other conditions: Cancers and rheumatic/autoimmune diseases
• Medications you are taking to treat other health conditions may also cause fatigue. This can
include anti-depressants and anti-anxiety medications, sedative medication, some blood
pressure medications, chemotherapy, radiation therapy, and steroids.
Ravi Nair Physiotherapy College
8. 2) LIFESTYLES
Lifestyle causes include:
• Sleep disturbances: If you are not getting enough sleep, too much sleep, or waking up during the night, you may
experience daytime fatigue.
• Diet: If you are eating a lot of high-carb, high-fat, or quick-fix foods, sugary foods and drinks, or caffeinated
drinks, you are not providing your body enough fuel or nutrients to function at its best. Moreover, these foods
may cause you to experience energy boosts that quickly wear off, leading to a "crash" and worsening fatigue.
• Alcohol and drugs: Alcohol is a depressant that will slow down the nervous system and disturb sleep. Cigarettes
and caffeine will stimulate the nervous system and cause you trouble with falling asleep and staying asleep.
• Lack of regular activity: Physical activity is known for improving your health and well-being, reducing stress, and
improving your energy levels. It will also help you sleep better and reduce daytime fatigue.
• Individual factors: Personal or family illness or injury, having too many commitments, and financial problems can
cause a person to feel fatigued.
Ravi Nair Physiotherapy College
9. WORKPLACE RELATED FATIGUE
People who work night shifts may experience daytime fatigue. This is because the human body is
designed to sleep at night, and a person who works the night shift confuses the body’s circadian clock.
Poor workplace practices that can also contribute to fatigue include:
• Irregular working hours
• Physical labor
• Long hours
• Noisy workplaces
• Fixed concentration
• Repetitive tasks
Fatigue may also be caused by the following workplace stressors:
• Heavy workload
• Conflict with bosses or coworkers
• Workplace bullying
• Threats to job security

15. LOCAL ASSESMENT
Assessment procedure which indicate a fall in the strength or firing ability of the muscle fiber
can be used to determine fatigue.
-Muscular fatigue
-Fall strength or firing ability of the muscle fiber to determine fatigue
Commonly used technique are:-
• Electrophysiological
• Decremental studies
• EMG
• MMT
• Endurance testing
16. • SYSTEMIC ASSESSMENT
a) Anaerobic Assesment
b) Measurement of blood lactate level
c) Measurement of aerobic capacity
d) Measurement of energy expenditure
A) ANAEROBIC FATIGUE:- Assessment of the fatigue during
anaerobic power performance when vigorous exercises
continues for more than few seconds.
Anaerobic Fatigue is the percentage decline in the power output
during the test.
The various test which are used for anaerobic fatigue are
following:-
18. WINGATE CYCLE ERGOMETER TEST:-
It is capable of identifying two primary measures-
1) Anaerobic capacity
2) Anaerobic power outputs
Ravi Nair Physiotherapy College
19. • The presence of lactate in the muscle and blood indicates the contribution
from anaerobic metabolism to give energy to the work performed.
• Measurement of lactate in blood can give an idea regarding the extent of
fatigue.
Ravi Nair Physiotherapy College
B) MEASUREMENT OF BLOOD LACTATE LEVEL
20. LACTATE THRESHOLD TEST
• These tests are typically called step tests and rely on stepping up the intensity of the
exercise effort over 2, 3 or more steps.In order to track your lactate threshold
• A simple step test would look like this:
Ravi Nair Physiotherapy College
21. C) MEASUREMENT OF AEROBIC CAPACITY
It gives an information regarding fatigue that occurs due to lack of oxygen supply to the
exercising structures. This type of aerobic fatigue occurs during a prolonged exercise
program when the energy producing sources are the aerobic system.
The aerobic capacity of an individual can be measured by calculating his maximal oxygen
consumption which is given VO2 Max.
It is given with flick’s equation:-
Ravi Nair Physiotherapy College
VO2 Max = cardiac output x arteriovenous O2 difference
= Q x a-VO2
Cardiac output(Q) = heart rate x stroke volume
Arteriovenous O2 difference = arterial O2 – venous O2
22. D) MEASUREMENT OF ENERGY EXPENDITURE
Energy expenditure can also be determined easily by open circuit portable
spirometry and also by telemetry.

2) fatigue severity scale
3) Multidimensional fatigue inventory
4) Brief fatigue inventory
5) Chalder fatigue scale
6) Piper fatigue scale
7) BORG rating of perceived exertion(RPE)
24. Ravi Nair Physiotherapy College
1) MODIFIED FATIGUE IMPACT SCALE (MFIS)
•The MFIS is a modified form of the Fatigue Impact Scale, This instrument provides an
assessment of the effects of fatigue in terms of physical, cognitive, and psychosocial
functioning. The full-length MFIS consists of 21 items while the abbreviated version has
5 items.
•The MFIS is a structured, self-report questionnaire that the patient can generally
complete with little or no intervention from an interviewer.
• Scoring- The total score for the MFIS is the sum of the scores for the 21 items.
Individual subscale scores for physical, cognitive, and psychosocial functioning can also
be generated by calculating the sum of specific sets of items.
25. • For example some questions are:-
• RESULTS- A higher score means fatigue is more significantly affecting your life. For
example, someone with a score of 70 is affected by fatigue more than someone with a
score of 30. The three subscales provide additional insight into how fatigue affects your
day-to-day activities.
26. 2) FATIGUE SEVERITY SCALE
•The Fatigue Severity Scale (FSS) is a 9-item scale which measures the severity
of fatigue and its effect on a person's activities and lifestyle in patients with a
variety of disorders. It was originally devised for people with Multiple
Sclerosis (MS) or Systemic lupus erythematosus.
Method of Use
• A self-report scale of nine items about fatigue, its severity and how it affects
certain activities. Answers are scored on a seven point scale where 1 =
strongly disagree and 7 = strongly agree. This means the minimum score
possible is nine and the highest is 63. The higher the score, the more severe
the fatigue is and the more it affects the person's activities.
Test-retest Reliability
• The study reported excellent test-retest reliability (ICC = 0.91)
28. 3) BRIEF FATIGUE INVENTORY
Consists of nine items that look at fatigue in the past that are rated on a 0 -10
numeric rating scale where 0 is no fatigue or does not interfere and 10 is
bad fatigue or completely interferes with activity/work.
• Reliability: Cronbach alpha
reliability ranges from 0.82 to 0.97
29. Ravi Nair Physiotherapy College
4) MULTIDIMENSIONAL FATIGUE INVENTORY
•The Multidimensional Fatigue Inventory (MFI) is a 20-item self-report instrument
designed to measure fatigue. It covers the following dimensions: General Fatigue, Physical
Fatigue, Mental Fatigue, Reduced Motivation and Reduced Activity.
•This new instrument was tested for its psychometric properties in cancer patients
receiving radiotherapy, patients with the chronic fatigue syndrome, psychology students,
medical students, army recruits and junior physicians.
•Reliability and Validity In an initial psychometric evaluation, developers reported an
internal consistency ranging from .53 to .93

33. • Overcoming or reversal of fatigue
• Body systems repair and damaged tissues & replenish energy stores.
• Insufficient recovery can lead to overtraining or long term(chronic) fatigue.
• Includes number of different processes.
34.
35. SLEEP
-Sleep is the most important recovery modality
Night sleep: adults 7 – 9 hr; kids 9-10 hr
Day nap: 15-20 min
-However, too much or too little sleep can affect performance Not only quantity but
also quality of sleep is important
Deep sleep (75-80%): growth and repair
REM sleep (20-25%): neural function
SLEEPING TIPS: THINGS TO DO
-Practice relaxation techniques before going to bed (eg soft music and muscle
relaxation)
-Lie down to sleep ONLY when you are sleepy
36. -If you don't fall asleep within 30 min after turning out the light, get up
and do some relaxation again
-If you wake up in the night and can't get back to sleep, get up and do
some relaxation again Get up at the same time every day
SLEEPING TIPS: THING NOT TO DO
Caffenine eg (coffee, tea, and coke)
Nicotine (Alcohol leads to disturb sleep patterns)
High protein and large meal
37. REPLENISH ENERGY STORES NUTRITION
-Replenish glycogen stores (CHO) (65% diet) -Should be replenished in first 15-30 mins with
high Gl foods
Fluid: continue re-hydrating until urine colour is clear Sports drink
Oxygenated water eg:- OxyShot
Chocolate milk: carbohydrate + protein
Fuel: immediately after (30 min to 2 hr)
Carbohydrate: 1 g/kg/hr
Glycemic index (GI): glucose and insulin ↑
perhaps consumed every 15-30 min
REHYDRATION
Be hydrated before exercise 400-600mL in
2 hours prior
200-300mL every 15-20 mins during exercise
38. PSYCHOLOGICAL SKILLS
• Emotional recovery
mood-lifting activities (eg music, movie)
→ should be individualized
• Relaxation techniques
Meditation, Visualization, Flotation
HYDROTHERAPY or HYDRO-RECOVERY
- External application of water (liquid, ice, hot, cold or warm ) to heal and recover
• Pool recovery (aqua exercise): 15 - 40 min
• Spa (water jet massage) : 20 min
helps muscle recovery,
• Shower: within 5 – 10 min after training or competition
• Bath -hot bath: can improve quality of sleep
-
39. CRYOTHERAPY
• Ice packs, pool sessions, ice baths and ice vests.
• Reduced blood flow to reduce swelling and fluid retention around joints
• Important for damaged or injured sites
• Causes vasoconstriction of blood vessels & removal of waste products.
• Maintains core body temprature.
HOT AND COLD CONTRAST BATH
• Alternate between hot & cold shower.
• EFFECTS- relaxes muscles
assists neurological recovery
removal of waste products &
deliver nutrients
40. PHYSICAL THERAPY
• STRETCHING- gentle, prolonged or brisk stretching According to condition.
- for performance enhancement
- 50% fewer injury rate
• STRENGTHNING- of specific muscle group muscles (for increasing power & muscle
endurance)
• MODALITIES – for releaving pain(TENS,IFT) FOR Tissue healing(ultrasound)
• COMPRESSSION GARMENTS
- increased blood flow
- increase venous return & reduce blood pooling
- increase lactate clearance(decreasing blood lactate levels
- enhance proprioception
- decrease DOMS
41. 3 LEVELS OF RECOVERY
LEVEL - 3 : ENHANCE RECOVERY THROUGH TRAINING
LEVEL – 2 : ACTIVE RECOVERY
LEVEL – 1 : PASSIVE RECOVERY
42.
43. TAPERING
• TAPERING, refers to a progressive reduction in training load prior to
athletic competition aiming to reduce fatigue while
maintaining/enhancing training adaptations.
• This reduction in fatigue and maintenance/enhancement of training
adaptions has a substantial impact on athletic performance, normally
leading to improvements of 2–3%.
• Maintaning training intensity, reduce volume by 60-90%, maintain
frequency at more than 80%.
