About this study
Official title: Effects of High-intensity Interval Training With an Eccentric Hamstring Exercise Program in Futsal Players
Physiotherapy protocols based on high-intensity interval training (HIIT) or eccentric hamstring exercises like Nordic Curl (NC) have been scarcely studied in futsal players. The hypothesis of this study is that a HIIT combined with an NC exercise program is more effective than a HIIT-only program in improving physical and functional characteristics in futsal players.
Read the detailed description
The objective of this study was to compare the effectiveness of a HIIT combined with an NC exercise program versus a HIIT-only program in futsal players. Therefore, a randomized controlled trial will be carried out. Futsal players will be divided into 1) HIIT+NC group and 2) HIIT group. The HIIT+NC group will perform a HIIT circuit combined with 3 sets of 10 NC repetitions for 4 weeks, while the HIIT group will perform the same protocol without NC exercise. BMI, intermittent work performance, vertical jump performance without and with arms, isometric strength of quadriceps and hamstrings, and the isometric H/Q ratio, will be assessed before and after the interventions.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
HIIT and Nordic Curl exercise programOther
The training program in the HIIT+NC group was divided into the following parts: i) warm-up (10 minutes); ii) HIIT (25 minutes) consisting of a circuit of eight exercises; iii) Nordic curl exercise (10 mintues); and iv) stretching.
HIIT-only programOther
The HIIT group performed the same exercises in the warm-up, HIIT and stretching sections as the HIIT+NC group, however, they did not perform the NC eccentric exercises.
| Study group | Role | What they receive |
|---|---|---|
| HIIT and Nordic Curl exercise group | Experimental | The participants will perform a weekly 50 minutes session for four weeks. Receives: Other: HIIT and Nordic Curl exercise program |
| HIIT-only group | Active comparator | The participants will perform a weekly 40 minutes session for four weeks. Receives: Other: HIIT-only program |
What is being measured
The primary outcome is the main question the study is designed to answer.
Intermittent work performance
Intermittent work performance will be assessed with the 30x15 Intermittence Test (30x15IFT). The speed of the test will be recorded in km/h. The higher the speed achieved, the better work performance.
Measured: Baseline

Intermittent work performance will be assessed with the 30x15 Intermittence Test (30x15IFT). The speed of the test will be recorded in km/h. The higher the speed achieved, the better the work performance.
Measured: After the intervention (4 weeks)
Secondary outcomes (10)
Vertical jump performance without arm impulse
Vertical jump performance without arm impulse will be measured with the Counter Movement Jumping Test (CMJ). The jump height was calculated using the My Jump 2 program (My Jump Lab, Madrid, Spain) in cm. The higher the height achieved, the better the vertical jump performance.

Measured: After the intervention (4 weeks)
Maximal quadriceps isometric strength
Maximal quadriceps isometric strength will be measured using the Adapted Quadriceps Sphygmomanometer Test in mmHg. The higher the pressure (mmHg) achieved, the better the quadriceps isometric strength.
Measured: Baseline
Maximal quadriceps isometric strength
Maximal quadriceps isometric strength will be measured using the Adapted Quadriceps Sphygmomanometer Test in mmHg. The higher the pressure (mmHg) achieved, the better the quadriceps isometric strength.
Measured: After the intervention (4 weeks)
Maximal hamstrings isometric strength
Maximal hamstrings isometric strength will be measured using the Adapted Hamstrings Sphygmomanometer Test in mmHg. The higher the pressure (mmHg) achieved, the better the hamstrings isometric strength.
Measured: Baseline
Maximal hamstrings isometric strength
Maximal hamstrings isometric strength will be measured using the Adapted Hamstrings Sphygmomanometer Test in mmHg. The higher the pressure (mmHg) achieved, the better the hamstrings isometric strength.
Measured: After the intervention (4 weeks)
Isometric hamstrings/quadriceps ratio
Isometric hamstrings/quadriceps (H/Q) ratio will be calculated by dividing the values obtained previously in the maximum isometric strength test of the hamstrings by those obtained in the quadriceps test. The value closer to 1, the greater the balance between the hamstrings and quadriceps muscles.
Measured: Baseline
Isometric hamstrings/quadriceps ratio
Isometric hamstrings/quadriceps (H/Q) ratio will be calculated by dividing the values obtained previously in the maximum isometric strength test of the hamstrings by those obtained in the quadriceps test. The value closer to 1, the greater the balance between the hamstrings and quadriceps muscles.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Physiotherapy protocols based on high-intensity interval training (HIIT) or eccentric hamstring exercises like Nordic Curl (NC) have been scarcely studied in futsal players. The hypothesis of this study is that a HIIT combined with an NC exercise program is more effective than a HIIT-only program in improving physical and functional characteristics in futsal players.
Detailed description
The objective of this study was to compare the effectiveness of a HIIT combined with an NC exercise program versus a HIIT-only program in futsal players. Therefore, a randomized controlled trial will be carried out. Futsal players will be divided into 1) HIIT+NC group and 2) HIIT group. The HIIT+NC group will perform a HIIT circuit combined with 3 sets of 10 NC repetitions for 4 weeks, while the HIIT group will perform the same protocol without NC exercise. BMI, intermittent work performance, vertical jump performance without and with arms, isometric strength of quadriceps and hamstrings, and the isometric H/Q ratio, will be assessed before and after the interventions.

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?
Intermittent work performance (time frame: Baseline). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05854459, which also lists 2 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 11 May 2023.
