About this study

Official title: Short Sprint Interval Training as an Effective Exercise Strategy for People With Multiple Sclerosis

The goal of this clinical trial is to learn whether a short sprint interval training protocol on a cycle ergometer can improve physical function, walking, muscle strength, exercise capacity, fatigue, cognitive processing speed, and patient-reported outcomes in people with multiple sclerosis.

The main questions it aims to answer are:

Read more
  1. Does short sprint interval training improve walking performance, lower-limb coordination, muscle strength, exercise capacity, fatigue, and cognitive processing speed in people with multiple sclerosis?
  2. How do participants respond to short sprint interval training in terms of heart rate, power, cadence, perceived exertion, and affective valence?
  3. What adverse events or unintended effects, if any, occur during the intervention?

Researchers will compare short sprint interval training with usual physical activity to see if this exercise program improves physical, cognitive, and patient-reported outcomes.

Participants will:

  1. Be randomly assigned to either a short sprint interval training group or a usual physical activity group.
  2. Complete assessments before and after the 2-week training period.
  3. Continue their usual physical activity if they are assigned to the control group.
  4. Complete 6 supervised exercise sessions over 2 weeks if they are assigned to the short sprint interval training group.
  5. During each exercise session, perform short 5-second high-intensity cycling sprints on a recumbent cycle ergometer, separated by recovery periods.
  6. Complete walking, strength, stepping, calf endurance, fatigue, and cognitive processing speed assessments.

What participants receive

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

  • Short sprint interval trainingOther

    Participants will perform a supervised short sprint interval training program on a recumbent cycle ergometer for 2 weeks, with 3 sessions per week. Each session will include a 5-minute warm-up at an easy intensity, followed by repeated 5-second high-intensity cycling sprints separated by 40 seconds of active recovery. The number of sprints will increase progressively across sessions from 5 to 9, with a reduced number of sprints in the final session.

What is being measured

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

  1. Change in Symbol Digit Modalities Test Oral Score

    Cognitive processing speed will be assessed through the oral version of the Symbol Digit Modalities Test (SDMT). The outcome will be reported as the total number of correct responses. Scores range from 0 to 110, with higher scores indicating better cognitive processing speed. Change from baseline to Week 4 will be evaluated.

    Measured: Baseline and Week 4

  2. Change in Fatigue Severity Scale Score

    Fatigue severity will be assessed through the Fatigue Severity Scale (FSS). The FSS includes 9 items, each scored from 1, indicating strongly disagree, to 7, indicating strongly agree. The total score is calculated as the mean of the 9 items and ranges from 1 to 7, with higher scores indicating greater fatigue severity. Change from baseline to Week 4 will be evaluated.

    Measured: Baseline and Week 4

  3. Change in Timed 25 Foot Walk Time

    Walking speed will be assessed through the Timed 25-Foot Walk (T25FW). This test will be performed forwards and backwards, at a comfortable pace and as fast as safely possible, with 2 trials for each condition. Time will be recorded in seconds using a stopwatch. The outcome will be reported as the lowest time recorded for each condition, with lower times indicating a faster walking speed. Change from baseline to Week 4 will be evaluated.

    Measured: Baseline to Week 4

  4. Change in the Six-Spot Step Test Time

    Dynamic walking performance and lower-limb coordination will be assessed through the Six-Spot Step Test (SSST). The SSST will be performed after a familiarization trial as fast as safely possible for two trials with each leg. Time will be recorded in seconds using a stopwatch, with lower times indicating better lower-limb coordination and walking performance. The outcome will be reported as the lowest time recorded for each leg. Change from baseline to Week 4 will be evaluated.

    Measured: Baseline and Week 4

Secondary outcomes (5)
  1. Change in Handgrip Strength

    Handgrip strength will be assessed using a hand dynamometer and recorded in kg. The outcome will be the best of 3 trials, with higher scores indicating greater handgrip strength. Change from baseline to Week 4 will be evaluated.

    Measured: Baseline and Week 4

  2. Change in Lower-limb Muscle Power

    Lower-limb muscle power will be assessed through the 5-repetition Sit-to-Stand test (5-STS) with the time recorded in seconds with a stopwatch. The outcome will be reported as the best of the 2 trials, with lower times indicating greater muscle power. Change from baseline to Week 4 will be evaluated.

    Measured: Baseline to Week 4

  3. Change in Lower-limb endurance and strength

    Lower-limb endurance and strength will be assessed through the 30-second Sit-to-Stand test (30-STS), with the number of repetitions visually counted. The outcome will be reported as the best of 2 trials, with a higher number of repetitions indicating greater lower-limb endurance and strength. Change from baseline to Week 4 will be evaluated.

    Measured: Baseline to Week 4

  4. Change in Cardiorespiratory fitness

    Cardiorespiratory fitness will be assessed using the Young Men's Christian Association 3-minute step test (YMCA step test). Heart rate will be assessed with a chest strap heart-rate monitor. The outcome will be recorded as the mean recovery heart rate after 60 s of rest, with lower scores indicating better cardiorespiratory fitness. Change from baseline to Week 4 will be evaluated.

    Measured: Baseline and Week 4

  5. Change in Plantar flexor strength-endurance

    Plantar flexor strength-endurance will be assessed using the standing single-leg heel-rise test. The outcome will be reported as the number of repetitions visually counted from each leg in 1 trial, with a higher number of repetitions indicating greater plantar flexor endurance capacity. Change from baseline to Week 4 will be evaluated.

    Measured: Baseline to Week 4

The record says: finished, as of the sponsor's last update on 29 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

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?

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07804264, which also lists 23 linked publications.

Does a listing mean the treatment is approved or proven to work?

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

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Oct 2026.
