Detaljeret beskrivelse
Day 1: Informed Consent signature and Clear (IC); Application of the Minnesota Living with Heart Failure Questionnaire (MLHFQ); Measurement of the muscle thickness with use of ultrasound; Anatomical points definition for electrode placement of Electromyography (EMG); Warming up on stationary bike; Subject's position in the Isokinetic, placement of EMG electrodes and NIRS´ optodes; Baseline measurement (peak torque and muscle fatigue protocol); Stretching exercises for the lower limbs muscles; 48-hour interval.
Day 2: Warming up on stationary bike; LASER / Placebo application; Subject's position in the Isokinetic, placement of EMG electrodes and NIRS´ optodes; Peak torque and muscle fatigue protocol in the Isokinetic equipment; Stretching exercises for the lower limbs muscles; 48-hour interval.
Day 3: Warming up on stationary bike; LASER / Placebo application; Subject's position in the Isokinetic, placement of EMG electrodes and NIRS´ optodes; Peak torque and muscle fatigue protocol in the Isokinetic equipment; Stretching exercises for the lower limbs muscles.

Beskrivelse
Inclusion Criteria:
- Participants who consent to cooperate with this study and meet the following inclusion criteria: a) to have a clinical diagnosis of heart failure (ejection fraction of the left ventricle less than 40% secondary to ischemia or idiopathic dilated cardiomyopathy) functional class II or III, according to the NYHA classification ; b) be medically stable in the 30 days prior to enrollment in the study and, c) not have participated or are participating in cardiac rehabilitation program.
Exclusion Criteria:
- The sample shall be excluded: a) participants who did not consent to participate in the study, b) participants with present insufficient level of understanding for the tests, c) participants that are making use of anti-inflammatory drugs steroids and nonsteroidal, d) the ones that have limitations to perform physical activity (exacerbation of fatigue, extreme breathlessness, arthritis, claudication, angina), e) participants with musculoskeletal disease, brain vascular disease and psychiatric illness and f) the ones who not adhere to the schedule of activities proposed in the study.

Aktiv komparator: LASER
Subject will receive application of LASER before muscle fatigue protocol. Note: this is a crossover study. |
Low level LASER therapy will be applied in six different regions of the thight from the dominant limb, before a fatigue protocol using a isokinetic equipment.
|

Placebo komparator: LASER PLACEBO
Subject will receive application of LASER (now deactivated) before muscle fatigue protocol. Note: this is a crossover study. |
The low level LASER therapy turned off (placebo) will be applied in six different regions of the thight from the dominant limb, before a fatigue protocol using a isokinetic equipment.
