Study summary

The purpose of this study is to investigate the effects of a 12-week flexi band resistance training program compared to different whole-body electromyostimulation (WB-EMS) exercise programs on muscle strength, body composition (in particular muscle mass), cardiorespiratory fitness, inflammation, and patient-reported subjective outcomes (e.g. quality of life, fatigue, performance status) in patients with malignant disease undergoing curative or palliative anti-cancer treatment.

What researchers measure

Primary outcomes

  1. Muscle strength

    Muscle strength of the five major muscle groups (chest, upper back, lower back, abdominals, legs) will be assessed by using specific strength-training devices and estimated using the one Repetition Maximum (1-RM, the maximum amount of weight \[kg\] that can be lifted for one repetition)

    Time frame: 12 weeks

Secondary outcomes

  1. Muscle Mass

    Muscle mass (kg) will be measured by Bioelectrical Impedance Analysis (BIA)

    Time frame: 12 weeks

  2. Fat Mass

    Fat mass (kg) will be measured by Bioelectrical Impedance Analysis (BIA)

    Time frame: 12 weeks

  3. Total Body Water

    Total body water (L) will be measured by Bioelectrical Impedance Analysis (BIA)

    Time frame: 12 weeks

  4. Cardiorespiratory Fitness (CRF)

    CRF will be assessed by measuring Maximum Oxygen uptake (VO2max)

    Time frame: 12 weeks

  5. Inflammation status

    Inflammation will be assessed by measuring blood levels (mg/L) of c-reactive protein (CRP) and high-sensitivity c-reactive protein (hs-CRP).

    Time frame: 12 weeks

  6. Patient-reported performance status-1

    Patient-reported performance Status will be assessed using the ECOG Performance Status questionnaire. It describes a patient's level of functioning in terms of their ability to care for themself, daily activity, and physical ability. The score ranges from 0-5 (lower values = better outcome).

    Time frame: 12 weeks

  7. Patient-reported performance status-2

    Patient-reported performance status-2 will be assessed using the Karnofsky index. It is used methods to assess the functional status of a Patient. The score ranges from 0-100 (higher value = better outcome).

    Time frame: 12 weeks

  8. Patient-reported Quality of Life (QoL)

    Patient-reported QoL will be assessed using the EORTC QLQ-C30 questionnaire. It contains 30 questions (items), representing various aspects/dimensions of QoL (physical, role, emotional, cognitive and social), and 3 symptom scales (fatigue, pain and nausea).The scales of the different dimensions of QoL (higher values = better outcome) and symptoms (lower values = better outcomes) range from 0-100.

    Time frame: 12 weeks

  9. Patient-reported Fatigue

    Fatigue will be assessed using the FACIT-Fatigue scale. It contains 13 items (different aspects/dimensions of fatigue) each assessed on a scale of 0-4, with lower values indicating a better outcome).

    Time frame: 12 weeks

  10. Patient-reported Physical Activity

    Patient-reported Physical Activity (PA) will be assessed using the the International Physical Activity Questionnaire (IPAQ). IPAQ records 4 aspects of PA (job-, transportation-, housework-, and leisure-time-related). There are two forms of output from scoring the IPAQ. Results can be reported in categories (low, moderate or high PA levels) or as a continuous variable (MET minutes a week, 1 MET = resting energy expenditure). MET minutes represent the amount of energy expended carrying out physical activity. High PA = at least 1500 MET minutes/week; moderate PA: at least 600 MET minutes/week; low PA: \< 600 MET minutes/week. Higher values represent a better outcome.

    Time frame: 12 weeks

  11. Objective Physical Activity

    Obejective measurement of physical activity will be preformed using Pedometers. Higher values represent a better outcome.

    Time frame: 12 weeks

  12. Cardiometabolic Risk Profile (Metabolic Syndrome Z-Score, MetS)

    MetS will be calculated MetS-Z-Score will be calculated from each individual's measures of waist circumference (cm), mean arterial blood pressure (mmHg), blood levels of glucose (mg/dL), triglycerides (mg/dL), and HDL-cholesterol (mg/dL), based on equations specific to sex.

    Time frame: 12 weeks
