Registration Number
NCT05854459
Lead Sponsor
University of Valencia
Brief Summary

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.

Primary Outcome Measures
NameTimeMethod
Intermittent work performanceAfter the intervention (4 weeks)

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.

Secondary Outcome Measures
NameTimeMethod
Vertical jump performance without arm impulseAfter the intervention (4 weeks)

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.

Vertical jump performance with arm impulseAfter the intervention (4 weeks)

Vertical jump performance with 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.

Isometric hamstrings/quadriceps ratioAfter the intervention (4 weeks)

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.

Maximal quadriceps isometric strengthAfter the intervention (4 weeks)

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.

Maximal hamstrings isometric strengthAfter the intervention (4 weeks)

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.
