About this study

Official title: Effects of a Strength Exercise Program on Muscular Health in People With CF Treated With Modulators of the Cystic Fibrosis Transmembrane Conductance Regulator Receptor (CFTR)

Recently, the treatment of Cystic Fibrosis (CF) incorporated new modulators/enhancers of the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR). It is thus increasingly important to study the side effects of these drugs, their extrapulmonary effects and possible interaction with other drugs and with exercise. For this purpose, a randomized controlled trial is proposed to determine the effects of a telematic exercise intervention on muscle health, in a group of 48 children and adolescents with CF treated with these new generation CFTR modulators. They will be randomly assigned to two groups (exercise and control group). The effect of the intervention will be analysed measuring the variables of muscle health, cardiorespiratory fitness, lung function, body composition, inflammatory biomarkers and miRNAs. After completion of the intervention program, adherence to exercise and clinical evolution after one year will be analysed.

Specific objectives

  1. To determine the effects of a strength exercise intervention in a group of children and adolescents with cystic fibrosis treated with new generation CFTR modulators on: (1.i) peripheral muscle strength; (1.ii) respiratory muscle strength; (1.iii) muscle mass and (1.iv) biomarkers of muscle damage.
  2. To determine the effects of a strength exercise intervention in a group of children and adolescents with cystic fibrosis being treated with new generation CFTR modulators on: (2.i) cardiorespiratory fitness; (2.ii) body composition and (2.iii) lung function.
  3. To determine the effects of a strength-based exercise intervention in a group of children and adolescents with cystic fibrosis treated with new-generation CFTR modulators on: (3.i) biomarkers of inflammatory status and (3.ii) expression of associated miRNAs.
  4. To determine the effects of a strength-based exercise intervention in a group of children and adolescents with cystic fibrosis treated with the new generation CFTR modulators on the levels of Elexaxcaftor/Ivacaftor/Tezacaftor and their metabolites.
  5. To assess the clinical evolution and adherence to exercise after 6 months of the programme in children and adolescents with cystic fibrosis treated with the new generation of CFTR modulators.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ExerciseOther

    16-week exercise intervention: At the beginning of the intervention, we will conduct a face-to-face familiarisation session with the exercises of the training programme. The intervention will consist of 2 sessions/week for 16 weeks. Each session consists of three stages: (i) Warm-up: 10 min of joint mobility and low intensity exercises involving the musculature to be worked in that session; (ii) Main part: circuit training mainly composed of strength exercises targeting the different muscle groups of the body and playing activities (iii) Cool down: 10 min with guided breathing work and stretching of the main muscle groups worked

Study groups in NCT06322446
Study groupRoleWhat they receive
InterventionExperimentalTelematic Exercise: A remotely supervised resistance exercise program will be carried out for 16 weeks, with two weekly sessions lasting approximately 60 minutes each. Training will be performed in groups of four patients, according to their lung function/physical fitness. The first training session will be on site (University) for familiarization, planning and adjustment of the exercises, and the following sessions will be performed online. Each session is divided into: (i) Warm-up and joint mobility; (ii) main part: strength exercises for different muscle groups; and (iii) cool down: stretching and breathing exercises.
Receives: Other: Exercise
ControlNo interventionControl group will follow routine recommendations from the multidisciplinary CF team based on WHO´s guidelines

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Changes in peripheral muscle strength

    Upper and lower limbs muscle strength (kg) will be evaluated using dynamometers.

    Measured: Baseline, pre-intervention and immediately after the intervention.

  2. Changes in inspiratory/expiratory muscle strength (MIP/MEP) (cmH2O)

    Inspiratory and expiratory muscle strength: maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) will be measured.

    Measured: Baseline, pre-intervention and immediately after the intervention

  3. Changes in functional capacity: lower limbs power capacity

    30 seconds sit-to-stand test. Unit of measurement: number of repetitions.

    Measured: Baseline, pre-intervention and immediately after the intervention

  4. Changes in functional capacity: walking capacity

    10m Time (s) Up and Go tests.

    Measured: Baseline, pre-intervention and immediately after the intervention

  5. Change in Cardiorespiratory fitness: maximal oxygen consumption

    To assess cardiorespiratory fitness, a treadmill and a gas analyser will be used. The test aims to determine maximal oxygen consumption (VO2peak in ml/kg/min). VO2peak will be recorded as the highest value obtained during a continuous 30 s period.

    Measured: Baseline, pre-intervention and immediately after the intervention

  6. Change in Cardiorespiratory fitness: Ventilatory threshold VT1

    To assess cardiorespiratory fitness, a treadmill and a gas analyser will be used. The test aims to determine the ventilatory threshold VT1 in response to maximal effort. VT1 will be determined using the criteria of an increase in both ventilatory equivalent for oxygen consumption (VE/VO2) and end-tidal oxygen pressure without an increase in ventilatory equivalent for carbon dioxide production (VE/VCO2).

    Measured: Baseline, pre-intervention and immediately after the intervention

Secondary outcomes (13)
  1. Changes in Pulmonary Function: forced vital capacity (FVC)

    Spirometry will assess: forced vital capacity (FVC) in milliliters and percentage of predicted value

    Measured: Baseline, pre-intervention and immediately after the intervention

  2. Changes in Pulmonary Function: Forced expiratory volume in the first second (FEV1)

    Spirometry will assess: forced expiratory volume in the first second (FEV1).Data will be expressed in absolute values and z-score based on the Global Lung Initiative (GLI) reference equation establishing as a limit of normality (LIN) a z-score value for FEV1 between -1.64 and + 1.64.

    Measured: Baseline, pre-intervention and immediately after the intervention

  3. Changes in the anthropometric and body composition: Weight

    Weight (kg)

    Measured: Baseline, pre-intervention and immediately after the intervention
