- Brief Summary
Physical exercise is an effective tool for the prevention of various chronic diseases. Fibromyalgia (FM) is a common chronic pain condition, in which patients may also experience a variety of other symptoms, including sleep disturbances, fatigue, stiffness, frequent episodes of pain and mental health problems, as well as possible gastrointestinal disorders. Furthermore, according to the American College of Rheumatology, such a generalised non-joint pain state occurs for at least three months in duration, predominantly in women over 50 years of age. In turn, chronic fatigue syndrome (CFS) presents as a disease characterised by persistent and debilitating fatigue lasting at least six months.
The origin of FM and CFS is unknown, although alterations in the central nervous system (CNS), as well as abnormalities in muscle physiology and immune/inflammatory response are suggested as the main causes.
In addition, most patients with FM are sedentary and in poor physical condition, exacerbated by pain, fatigue or depression, which can limit their daily activities and affect their quality of life and work opportunities. In this regard, physical exercise is considered the most important non-pharmacological strategy for the treatment of FM; however, many clinically relevant questions remain unanswered regarding the most effective approach to exercise therapy in FM patients.
Therefore, the main objective of this project is to analyse the possible physical and mental benefits of a physical exercise programme in people diagnosed with fibromyalgia and/or chronic fatigue syndrome.

- Primary Outcome Measures
Name Time Method PRE TEST Upper body dinamometry 7 days before protocol starts The dynamometer TKK 5105 (Takei Scientific Instruments Co., Ltd., Niigata, Japan) will be a typical analog handgrip dynamometer with an adjustable handle. This dynamometer will be used to assess the strength of the handgrip. The participant will be placed in a standing position, with the arms parallel but not touching the body, the shoulder adducted and neutrally rotated, and handgrip strength will be measured. The gadget handle will be modified to fit the size of the participants' hands so that each hand's index finger will be 90 degrees bent from the proximal to middle phalangeal joint. Every side will undergo two trials, alternately, with at least a minute of rest in between each session.
PRE TEST 10 meters walk test 7 days before protocol starts Participants will be instructed to walk 10 m (marked by taped lines) as quickly as possible without running. The test will be repeated after 2 minutes of rest. Verbal encouragement will be given throughout the test. Two photocells (Witty, Microgate, Italy) will be placed at 6 and 10 m to record the walking time. The shortest running time will be used for analysis
PRE TEST 2 minutes walk 7 days before protocol starts Participants will walk for 2 minutes at the maximum speed they can sustain during that time. The test takes place on a rectangular track (40 x 20 m) with the corners defined by cones. Subjects will be allowed to rest if they need to, but time will not be stopped during their rest period. The total distance (m) covered after 6 min of walking will be measured. All participants will be accompanied by the investigator during the test, but will not be allowed to engage in conversation.
PRE TEST Lower body dinamometry 7 days before protocol starts Participants will be seated on the isokinetic dynamometer chair (Biodex Medical System, NY) with both legs flexed at 90° and the testing leg's ankle will be strapped directly to a customized apparatus with a load cell (Model SML500, Interface Scottsdale, AZ, USA). To warm up, each subject will perform 3 progressive MVICs with 3 min of rest between attempts. To assess RFD in each leg, verbal encouragement will be given to the participants to apply "as much force as possible, as fast as possible" throughout the 2 consecutive maximal contractions. RFD will be analyzed using the time interval 0-200 (RFDlate). Subsequently, participants will perform 2 MVICs, each lasting for 5 s with 3 min of rest between contractions, with verbal encouragement. Maximal torque (MVIC) and time to peak voluntary torque (time-to-MVIC) will be evaluated. The right leg will always be evaluated first, and the trial with the highest value will be used for both RFD and MVIC.
PRE-TEST Time up and go test (TUG test) 7 days before protocol starts The test volunteers will be seated upright in a chair that could be adjusted to suit their leg length, with their legs bent at a 90-degree angle and their arms folded across their chests. Participants were to get up from their seats, move three meters forward, turn around, walk back to the starting point, and then sit down again. Using video capturing, the fastest time between the two trials was found and utilized for analysis

The Spanish version of the PSQI was used, Hita-Contreras et al.
PRE TEST BLOOD EXTRACTION 7 days before protocol starts To carry out the blood extraction, a qualified person will perform a sterile puncture in the cubitus median vein. After 15 minutes of extraction (in the case of serum, essential to facilitate clot formation), both tubes are centrifuged for 10 minutes at 1,600 rpm and at 22ºC. By this process, serum or plasma is isolated in the corresponding tubes and then aliquoted into eppendorf tubes with a total volume of 400 μl in each tube. The serum and plasma samples must be gradually frozen as they are obtained, until they are finally stored at -80ºC.
PRE TEST Balance test 7 days before protocol starts Determination of monopodal and bipodal equilibrium levels.
PRE TEST Beck Depression Inventory 7 days before protocol starts Spanish version (Sanz et al., 2003) of the Beck Depression Inventory (BDI) aimed at determining possible signs of depression in the past week. Higher scores indicate higher levels of depression.
PRE TEST Pain and fatigue Inventory 7 days before protocol starts -Brief Pain Inventory (BPI). Used to determine the intensity and interference of pain in daily activities. The higher the pain perception, the higher the score obtained. The Spanish version of Badía et al. (2003) was used. -Brief Fatigue Inventory (BFI). This questionnaire measures the intensity of fatigue in the last 24 hours and its interference with daily activities and work. The higher the perception of fatigue, the higher the score obtained (Valenzuela et al., 2002).
PRE TEST Ergospirometry 7 days before protocol starts The incremental protocol will include a 3-minute warm-up (4.5 km-h -1) followed by an increase to 6 km-h -1, with 1 km-h -1 increments every 45 seconds until exhaustion. Heart rate and the different spirometric variables, including respiratory exchange ratio (RER) and V̇O2 will be constantly monitored. The breath-by-breath method will be used to collect ventilation data during the incremental exercise test for individual assessment of maximal oxygen consumption capacity. The volume transducer and the Vyntus TM CPX gas analyser (Vyaire medical, INC, Hoechberg, Germany) shall be calibrated according to the manufacturer's instructions prior to each test.
POST-TEST Time up and go test (TUG test) 7 days after protocol ends The test volunteers will be seated upright in a chair that could be adjusted to suit their leg length, with their legs bent at a 90-degree angle and their arms folded across their chests.
