Outcome Measures

Primary Outcomes (2)

  • Exercise Capacity

    The maximal exercise capacity of the individuals will be evaluated by the incremental shuttle walk test. This test is a symptom-limited maximal field test that evaluates maximal exercise capacity with progressively increased walking speed.

    First Day

  • Chronotropic index

    The chronotropic index will be calculated using the results of the maximal exercise test.

    First Day

Secondary Outcomes (12)

  • Pulmonary function (Forced vital capacity (FVC))

    First Day

  • Pulmonary function (Forced expiratory volume in the first second (FEV1))

    First Day

  • Pulmonary function (FEV1 / FVC)

    First Day

  • Pulmonary function (Flow rate 25-75% of forced expiratory volume (FEF 25-75%))

    First Day

  • Pulmonary function (Peak flow rate (PEF))

    First Day

  • +7 more secondary outcomes

Study Arms (2)

Type 1 diabetes mellitus

Patients Maximal exercise capacity (Incremental shuttle walk test), respiratory functions (spirometer), respiratory muscle strength (mouth pressure measurement), peripheral muscle strength (dynamometer), respiratory muscle endurance ( incremental threshold loading test), physical activity level (multi sensor activity monitor), quality of life (World Health Organization (WHO) well-being index), fatigue (fatigue severity scale), shortness of breath (Modified Medical Research Council MMRC) will be evaluated.

Healthy Controls

Maximal exercise capacity (Incremental shuttle walk test), respiratory functions (spirometer), respiratory muscle strength (mouth pressure measurement), peripheral muscle strength (dynamometer), respiratory muscle endurance ( incremental threshold loading test), physical activity level (multi sensor activity monitor), quality of life (World Health Organization (WHO) well-being index), fatigue ( fatigue severity scale), shortness of breath (Modified Medical Research Council MMRC) will be evaluated.
