High-intensity Training for Improving Physical Performance of Aged Women

This study evaluates the adaptations on the functional capacity and cardiovascular in elderly after a physical activity program circuit training. The participants were divided into three groups: Circuit training based on high-intensity interval training group (HIICT), Circuit training at moderate intensity group (MICT) and Control group (CG).

About this study

Three groups of participants (circuit training based on high-intensity interval training, circuit training at moderate intensity and not training group) will enter the study. The intervention will consist of a physical exercise program in day centers.

Intensity progression will be encouraged according to the rate of perceived exertion. Progression of exertion will be "very hard", "extremely hard" and "maximal exertion" for HIT group, and "light", "somewhat hard" and "hard" for group. Assessment will be undertaken at two-time points: baseline and after 16 weeks of exercise training.

Assessment will include VO2 peak, functional capacity, health-related quality of life, cognitive state and daily physical activity.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Having 50 - 90 years old.
  • Not suffering chronic heart, respiratory or joint disease, taking medication or having a deteriorated level of mental health that could interfere in carrying out exercise programs.
  • Having 0 or 1 responses positive in the Physical Activity Readiness Questionnaire (ParQ). Only item 6, related to mild vascular diseases.
  • Being physically independent according to the scales Lawton and Brody, and Katz.

Exclusion criteria

  • Having uncontrolled arterial hypertension.
  • Having practiced during the previous 3 months or practicing at present a similar exercise to the one proposed in the study.
  • Attending sessions less than 80%.

Treatment and study plan

Experimental: High-intensity interval training group

Other

16 weeks of High-intensity interval training

Experimental: Moderate-intensity interval training group

Other

16 weeks of Moderate-intensity interval training

Primary outcomes

  1. Analyses changes in maximum oxygen consumption (VO2max).

    Time frame: Pre and post after sixteen weeks of intervention

    A modified Balke treadmill protocol will be used to estimate aerobic capacity (VO2max).

  2. Analyses changes in maximum oxygen consumption (VO2max).

    Time frame: Pre and post after sixteen weeks of intervention

    VO2max was assessed using the 6-Minute Walk Test. The participant should walk the longest distance possible in 6 minutes by walking continuously the 42 metres indicated on the floor. It measures the distance in meters

Secondary outcomes

  1. Analyses changes in heart rate reached in ergometry.

    Time frame: Pre and post after sixteen weeks of intervention

    Analyses during modified Balke treadmill protocol

  2. Analyses changes in blood pressure reached in ergometry.

    Time frame: Pre and post after sixteen weeks of intervention

    Analyses during modified Balke treadmill protocol

  3. Analyses changes in maximum speed reached in ergometry.

    Time frame: Pre and post after sixteen weeks of intervention

    Analyses during modified Balke treadmill protocol

  4. Analyses changes in duration test reached in ergometry.

    Time frame: Pre and post after sixteen weeks of intervention

    Analyses during modified Balke treadmill protocol

  5. Analyses changes in fat percentage.

    Time frame: Pre and post after sixteen weeks of intervention.

    Fat percentage (%) was assessed using bioimpedance analysis (OMROM BF-306).

  6. Analyses changes in body mass index (BMI).

    Time frame: Pre and post after sixteen weeks of intervention.

    BMI was assessed using bioimpedance analysis (OMROM BF-306).

  7. Analyses changes in gait.

    Time frame: Pre and post after sixteen weeks of intervention.

    Gait was assessed using the Timed Up and Go Test. To stand up from a standard arms chair, walk 3 meters, turn back the cone walk back and sit down to the chair. The time in seconds is record.

  8. Analyses changes in balance.

    Time frame: Pre and post after sixteen weeks of intervention.

    Balance was assessed using the One Leg Standing Test. This test consist in maintain one leg stance for as long as possible. The test was considered normal if the one leg standing time reached 30 seconds.

  9. Analyses changes in lower body strength.

    Time frame: Pre and post after sixteen weeks of intervention.

    Lower body strength was assessed using the Sit To Stand 30. For the Sit To Stand 30, the participant consist in measures how many repetition the participant can to stand up and sit down during 30 seconds.

  10. Analyses changes in upper body strength.

    Time frame: Pre and post after sixteen weeks of intervention.

    Upper body strength was assessed using the Arm Curl Test (30). For this test, the participant consist in measures how many repetition the participant can to curl up and curl down during 30 seconds.

  11. Analyses changes in maximal handgrip strength.

    Time frame: Pre and post after sixteen weeks of intervention.

    To measure the amount of strength developed by each hand in kg.

Other outcomes

  1. Analyses change in Self Assessed Physical Activity.

    Time frame: Pre and post after sixteen weeks of intervention.

    Physical activity was assessed using the Physical Activity Scale of the Elderly (PASE) questionnaire. The PASE is designed to assess physical activity in older persons. The total PASE score was computed by multiplying the amount of time spent in each activity (hours/week) or participation (yes/no) in an activity by empirically derived item weights and summing over all activities. PASE scores for this study ranged from 0 to 756 with higher scores indicating more physical activity.
