Assessment Of Cardiorespiratory Fitness And Recovery Capacity Among Women With Fibromyalgia
Bibliographic record
Abstract
Cardiorespiratory fitness (CRF) level among women living with fibromyalgia (FM) has been documented with some contradictory results most probably due to differences in the methodological approaches used. Furthermore, some studies have suggested that aerobic capacity was affected in patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) 24 hours after performing a maximal CRF test. To our knowledge, no research has looked at the capacity to recover after a maximal CRF test in FM patients, a disease often compared with ME/CFS. PURPOSE: To describe and compare the CRF and recovery capacity of women, who are mildly or moderately affected with FM, 24 hours after a maximal exercise test. METHODS: Twelve FM women were submitted twice to a maximal exercise test (BSU/Bruce ramp) interspersed by 24 hours (T1 & T2), until participants achieved volitional exhaustion. Gas exchange (Ergogard, Medisoft) and ECG (Quinton) were continuously monitored throughout the test. Blood lactate, blood pressure, pain intensity and rate of perceived exertion, were also assessed at different moments. The Revised Fibromyalgia Impact Questionnaire was completed by participants to determine their FM severity level. RESULTS: No significant differences in VO2peak (25,5±5,3 vs. 26,5±5,3 ml O2·kg−1·min−1, p>0,05) and VO2 at ventilatory threshold (VO2VT: 21,2±4,8 vs. 21,7±4,8 ml O2·kg−1·min−1, p>0,05) were found between T1 & T2. When considering the severity of the disease, mildly affected FM patients had a significantly greater CRF only at T2 (VO2peak: T2 = 30,4±3,3 ml O2·kg−1·min−1) and higher VO2 at the ventilatory threshold at T1 and T2 (VO2VT: T1 = 24,0±4,0; T2 = 24,9±3,2) when compared with moderately affected FM patients (VO2peak: T2 = 22,9±4,7 ml O2·kg−1·min−1 and VO2VT: T1 = 18,5±4,4; T2 = 18,7±4,5 ml O2·kg−1·min−1). Furthermore, CRF levels were lower than the general population. In fact, 75% of the VO2peak results were below the «Fair» category, of which 25% were below the «Very Poor» category, when compared to the ACSM normative values for VO2peak. CONCLUSION: In general, participants showed no significant difference in CRF and recovery after 24 hours. However, the severity of fibromyalgia negatively affected CRF in our study population and their CRF level was lower than the general population.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
