HIIT With an Eccentric Hamstring Exercise Program in Futsal Players
Study Details
Study Description
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.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: HIIT and Nordic Curl exercise group The participants will perform a weekly 50 minutes session for four weeks. |
Other: HIIT and Nordic Curl exercise program
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.
|
| Active Comparator: HIIT-only group The participants will perform a weekly 40 minutes session for four weeks. |
Other: HIIT-only program
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.

Outcome Measures
Primary Outcome Measures
- Intermittent work performance [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 work performance.
- Intermittent work performance [After 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
- Vertical jump performance without arm impulse [Baseline]
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 without arm impulse [After 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 impulse [Baseline]
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.
- Vertical jump performance with arm impulse [After 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.
- Maximal quadriceps isometric strength [Baseline]
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 quadriceps isometric strength [After 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 strength [Baseline]
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.
- Maximal hamstrings isometric strength [After 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.
- Isometric hamstrings/quadriceps ratio [Baseline]
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.
- Isometric hamstrings/quadriceps ratio [After 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.
