About this study

Official title: Effects of Diaphragmatic Kinesio Taping-Assisted HIIT Exercises on Aerobic Capacity, Anaerobic Capacity, and Balance in Trained Individuals

This randomized controlled trial evaluated whether diaphragmatic kinesio taping provides additional physiological and functional benefits when added to an 8-week supervised high-intensity interval training (HIIT) program in trained adults. Participants were randomly assigned to HIIT with or without diaphragmatic kinesio taping. Both groups completed the same supervised cycle-ergometer HIIT program three times per week for 8 weeks. Assessments were performed at baseline, week 4, and week 8 and included heart-rate variability, aerobic capacity, anaerobic performance, pulmonary function, balance, functional mobility, and body composition.

Read the detailed description

This randomized controlled trial investigated the additional effects of diaphragmatic kinesio taping during an 8-week supervised cycle-ergometer HIIT program in trained adults. Participants were randomly allocated in a 1:1 ratio to HIIT plus diaphragmatic kinesio taping or the same HIIT program without taping. Both groups trained three times per week. High-intensity intervals targeted 85-95% of maximum heart rate, with active recovery at 55-65% of maximum heart rate. Both groups also performed standardized diaphragmatic and pursed-lip breathing exercises as part of each supervised session.

Outcomes were assessed at baseline, week 4, and week 8. Assessments included resting heart-rate variability, spirometry, estimated maximal oxygen uptake, Wingate anaerobic performance, static and dynamic balance, timed up-and-go performance, and body composition. The study was conducted at Bursa Uludag University Faculty of Medicine, Department of Physiology.

What participants receive

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

  • High-Intensity Interval Training (HIIT)Behavioural

    Participants completed an 8-week supervised cycle-ergometer HIIT programme three times per week. Each session included 5 min of cycling at 50-60% HRpeak, 5 min of controlled diaphragmatic and pursed-lip breathing, progressive high-intensity intervals targeting 85-95% HRpeak with active recovery at 55-65% HRpeak, followed by 5 min of low-intensity cycling and 5 min of breathing exercises.

  • Diaphragmatic Kinesio TapingOther

    Diaphragmatic kinesio taping was applied before each supervised exercise session using a standardized bilateral technique along the lower costal margin. The tape remained in place between supervised sessions and was removed and replaced at each subsequent visit. At week-4 and week-8 assessments, the tape was removed immediately before outcome testing.

What is being measured

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

  1. Aerobic Capacity (Estimated V̇O₂max)

    Estimated maximal oxygen uptake derived from peak workload achieved during an incremental cycle-ergometer ramp test.

    Measured: Baseline, week 4, and week 8

  2. Wingate 5-s Peak Power (PP5)

    Body-mass-normalized highest mean power recorded over any 5-s epoch during the 30-s Wingate anaerobic test.

    Measured: Baseline, week 4, and week 8

  3. Heart Rate Variability (lnRMSSD)

    Natural logarithm of the root mean square of successive RR-interval differences measured during resting heart-rate variability assessment.

    Measured: Baseline, week 4, and week 8

  4. Dominant-Limb Y-Balance Composite Score

    The Y-Balance Test was performed bilaterally. The primary balance outcome was the dominant-limb normalized composite score, calculated as 100 × (anterior + posteromedial + posterolateral)/(3 × limb length). The dominant limb was defined as the leg preferentially used to kick a ball.

    Measured: Baseline, week 4, and week 8

Secondary outcomes (17)
  1. Heart Rate Variability - SDNN

    Standard deviation of normal-to-normal RR intervals (SDNN) obtained during resting heart-rate variability assessment.

    Measured: Baseline, week 4, and week 8

  2. Heart Rate Variability - LF/HF Ratio

    Ratio of low-frequency to high-frequency components of resting heart-rate variability derived from RR-interval analysis.

    Measured: Baseline, week 4, and week 8

  3. Wingate Mean Power

    Body-mass-normalized mean power generated over the 30-second Wingate anaerobic test.

    Measured: Baseline, week 4, and week 8

  4. Wingate Fatigue Index

    Measured: Baseline, week 4, and week 8

  5. Timed Up-and-Go (TUG)

    Time required to stand from a chair, walk 3 m, turn, return, and sit down; lower values indicate better functional mobility.

    Measured: Baseline, week 4, and week 8

  6. Forced Expiratory Volume in 1 Second (FEV₁)

    Forced expiratory volume in 1 second measured by spirometry according to standardized procedures.

    Measured: Baseline, week 4, and week 8

  7. Wingate Total Work

    Total work performed during the 30-second Wingate anaerobic test, normalized to body mass.

    Measured: Baseline, week 4, and week 8

  8. Forced Vital Capacity (FVC)

    Forced vital capacity measured by spirometry and expressed in liters.

    Measured: Baseline, week 4, and week 8

  9. FEV₁/FVC Ratio

    Ratio of forced expiratory volume in 1 second to forced vital capacity, expressed as a percentage.

    Measured: Baseline, week 4, and week 8

  10. Forced Expiratory Flow at 25-75% of FVC (FEF₂₅-₇₅)

    Mean forced expiratory flow during the middle 50% of the forced vital capacity manoeuvre, expressed in liters per second.

    Measured: Baseline, week 4, and week 8

  11. Peak Expiratory Flow (PEF)

    Maximum expiratory flow achieved during a forced expiratory manoeuvre, expressed in liters per second.

    Measured: Baseline, week 4, and week 8

    Vital capacity measured by spirometry and expressed in liters.

    Measured: Baseline, week 4, and week 8

    Maximum volume of air voluntarily ventilated over a standardized interval and expressed in liters per minute.

    Measured: Baseline, week 4, and week 8

  14. Single-Leg Stance

    Duration of single-leg standing balance performance, expressed in seconds; longer duration indicates better static balance performance.

    Measured: Baseline, week 4, and week 8

  15. Balance Error Scoring System (BESS)

    Total number of balance errors recorded during the Balance Error Scoring System assessment; lower scores indicate better postural stability.

    Measured: Baseline, week 4, and week 8

  16. Body Mass Index (BMI)

    Body mass index calculated as body mass in kilograms divided by height in meters squared (kg/m²).

    Measured: Baseline, week 4, and week 8

  17. Body-Fat Percentage

    Body-fat percentage estimated from seven-site skinfold measurements using the Jackson-Pollock and Siri equations.

    Measured: Baseline, week 4, and week 8

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Aerobic Capacity (Estimated V̇O₂max) (time frame: Baseline, week 4, and week 8). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
