    Impaired Skeletal Muscle Endurance in Adults With Complex Congenital Heart Disease is Associated With Local Muscle Oxygenation Kinetics2018Inngår i: Circulation: Abstracts From the American Heart Association's 2018 Scientific Sessions, 2018, Vol. 138, s. A15914-, artikkel-id Suppl. 1Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Introduction: Adults with complex congenital heart disease show reduced aerobic exercise capacity and impaired skeletal muscle function compared to healthy peers. Peripheral muscle factors are presumed to be important contributors, but the mechanisms are poorly understood. Hypothesis: Muscle oxygenation is associated with reduced skeletal muscle endurance in adults with complex CHD. Methods: Sixty-four adults with complex congenital heart disease (mean age 36.9±14.8 years, females n=19) were recruited from centers specialized in congenital heart disease. Seventy-four age and gender matched healthy peers were recruited as controls. Muscle oxygen saturation was successfully determined on the anterior portion of the deltoid muscle using near-infrared spectroscopy for 57 patients and 71 controls. Measurements were made at baseline, during isotonic shoulder flexions (0-90°) to exhaustion and during 60 seconds of recovery. Results: The adults with complex CHD performed fewer shoulder flexions (38±15 vs. 69±40, p <0.001), had lower muscle oxygen saturation at rest (58±17% vs. 69±18%, p <0.001), a slower desaturation rate at exercise onset (-9.5±5.9%/sec vs. -15.1±6.5%/sec, p <0.001), and a slower resaturation rate post exercise (3.9±2.8%/sec vs. 5.4±3.6%/sec, p =0.008) compared to the controls. Conclusions: A distinct association was found between muscle oxygenation kinetics and early muscle fatigue for adults with complex CHD. Our findings may give insight to the underlying mechanisms for the reduced aerobic exercise capacity for these patients, and therefore provide implications for design of exercise training protocols in this population.

    Slower Skeletal Muscle Oxygenation Kinetics in Adults With Complex Congenital Heart Disease2019Inngår i: Canadian Journal of Cardiology, ISSN 0828-282X, E-ISSN 1916-7075Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Adults with complex congenital heart disease (CHD) show reduced aerobic exercise capacity and impaired skeletal muscle function compared with healthy peers. Peripheral muscle factors are presumed to be important contributors to the aerobic capacity, but the mechanisms are poorly understood. The aim of the present study was to investigate differences between adults with CHD and controls in muscle oxygenation kinetics at rest, and during and after exercise.

    Methods: Seventy-four patients with complex CHD (mean age 35.6 ± 14.3 years, female n = 22) were recruited. Seventy-four age- and sex-matched subjects were recruited as controls. Muscle oxygenation was successfully determined on the anterior portion of the deltoid muscle using near-infrared spectroscopy in 65 patients and 71 controls. Measurements were made at rest, during isotonic shoulder flexions (0-90°) to exhaustion, and during recovery.

    Results: The patients with CHD performed fewer shoulder flexions (40 ± 17 vs 69 ± 40; P &lt; 0.001), had lower muscle oxygen saturation (StO2) at rest (58 ± 18% vs 69 ± 18%; P &lt; 0.001), slower desaturation rate at exercise onset (−9.7 ± 5.9 vs −15.1 ± 6.5% StO2 × 3.5 s−1, P &lt;0.001), and slower resaturation rate post exercise (4.0 ± 2.7 vs 5.4 ± 3.6% StO2 × 3.5 s−1; P = 0.009) compared with the controls. Conclusions: In comparison with age- and sex-matched controls, adults with complex CHD had slower oxygenation kinetics. This altered skeletal muscle metabolism might contribute to the impaired skeletal muscle endurance capacity shown and thereby also to the reduced aerobic capacity in this population.

    Muscle oxygenation, EMG, and cardiovascular responses for cabin attendants vs. controls2013Inngår i: Aviation, Space and Environmental Medicine, ISSN 0095-6562, E-ISSN 1943-4448, Vol. 84, nr 5, s. 478-485Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    INTRODUCTION: The goal was to investigate the effect of acute moderate hypobaric exposure on the physiological responses to sustained contractions (local) and light to moderate dynamic exercise (systemic) for cabin attendants (CAB) and a matched control group (CON).

    METHOD: There were 14 CAB and 13 CON who participated. The experimental protocol was designed as a 2 x 2 randomized crossover study for which subjects performed a forearm isometric test and a cycling test in normobaric (NORM) and hypobaric [HYPO; 574 mmHg approximately 8000 ft (2440 m) above sea level (ASL)] conditions. Oxygen saturation (StO2%) was measured in the extensor carpi radialis muscle at rest and during an isometric wrist extension (20% MVC). Heart rate (HR), ventilation (V(E)), and oxygen uptake (VO2) were measured at rest, during cycling exercise at intensities of 50 W and 100 W, and during recovery. Blood samples were collected and analyzed for hemoglobin concentrations.

    RESULTS: Local response: There was a significant effect of HYPO for both CAB and CON with a decrease in StO2% of 6.5% both at rest and during contraction. Systemic response: there was no general effect of HYPO on HR, VE, or VO2. No differences were found between groups in either the local or systemic response or in the blood parameters.

    CONCLUSION: This study shows an effect of moderate hypobaric exposure on local muscle oxygenation during rest and sustained contraction. Whether this has an impact on fatigue development during work among cabin attendants is discussed.
