    Variable weight training (VWT) significantly improved weight, muscle size, and strength in cystic fibrosis (CF) patients. This exercise intervention shows promise for managing CF, warranting further investigation into its effects.

    Area of Science:

    • Exercise Physiology
    • Pulmonary Rehabilitation
    • Clinical Research

    Background:

    • Exercise is recommended for cystic fibrosis (CF) patients, but aerobic exercise hasn't led to weight gain.
    • Variable weight training (VWT) has not been extensively studied in CF populations.

    Purpose of the Study:

    • To assess the impact of a six-month VWT program on body weight, pulmonary function, muscle characteristics, and social function in patients with moderately severe CF.

    Main Methods:

    • A six-month pilot study involving 12 adolescent and adult CF patients.
    • Included a three-month control period followed by six months of VWT.
    • Evaluated body weight, pulmonary function, muscle size and strength, and social function.

    Main Results:

    • Significant increases in body weight (2.88 kg), upper arm muscle size (1.6 to 1.8 cm), and muscle strength (16 to 32 muscle groups).
    • Significant decrease in residual volume (1.77 L) and RV/TLC (12.4 percent).
    • No significant improvements in other pulmonary or social function measures.

    Conclusions:

    • Variable weight training (VWT) is a safe and effective exercise modality for moderately ill CF patients.
    • VWT can lead to beneficial weight gain and increased muscle strength in individuals with cystic fibrosis.
    • Further research is warranted to explore VWT's effects on pulmonary function and CF morbidity.
