Hamstring tightness is a feeling that is often felt by futsal players, which can interfere with performance during playing. Previous studies suggest that stretching can solve it. However, feeling hamstring tightness is associated with weakness, so strengthening exercises are required to treat it. Strengthening exercises consist of concentric and eccentric exercises, which differ in the direction of muscle contraction. This study aimed to observe the effect of concentric, eccentric, and stretching exercises on muscle length, endurance, and power following hamstring tightness. 49 futsal players who experienced hamstring tightness participated in this study. Participants were divided into three groups consisting of Nordic Hamstring Exercise (NHE), Leg Curl Exercise (LCE), and control group (CTRL) - which only did stretching exercises. The exercises were carried out for 6 weeks, three times per week. The sit and reach test, Passive Knee extension test, Single leg bridge test, and Leg dynamometer tests were used to determine the changes in hamstring muscle before and after the exercises. One-way ANOVA was performed to compare changes between groups. All participants were found to be in the good category (28.78±5.53 cm) in sit and reach test and had low performance (39.13±16.77) in the leg dynamometer test before the intervention series. However, sit and reach test was shown not to be significantly different between groups (p>0.05) as well as ROM. Single-leg bridging test and leg dynamometer significantly differed between groups (p<0.05).This study suggests that feeling tight in the hamstring muscle is not correlated with muscle length. Concentric exercise increased strength more than eccentric and stretching. While concentric exercise increased the endurance of the hamstring muscle.

“…One study found that an isometric hip extension exercise leads to greater improvements in the single-leg hamstring bridge to fatigue test compared with the NHE (17). However, the single-leg hamstring bridge to fatigue test is not a valid measure of hamstring strength (18), and this study did not investigate sprinting performance or muscle architecture. In a more recent study (19), an isometric hip extension exercise was shown to improve isometric hamstring strength but failed to significantly change BFlh fascicle length.…”

Purpose Investigate impact of an isometric (ISO) or Nordic hamstring exercise (NHE) intervention, alongside a sprint training program on hamstring strength, architecture and sprinting performance in Australian Footballers. Methods Twenty-five male athletes undertook NHE (n = 13) or ISO (n = 12) training across a 38-week period (including pre-season and in-season). Biceps femoris long head (BFlh) architecture, isometric and eccentric knee flexor strength were assessed at baseline, end of pre-season (14-weeks) and at the conclusion of the intervention. Sprint times and force-velocity profiles were determined at baseline and at the end of pre-season. Results Following the intervention both groups had significant improvements in BFlh fascicle length (NHE: 1.16 cm, 95%CI 0.68 to 1.63 cm, d = 1.88, p < 0.001; ISO: 0.82 cm, 95%CI 0.57 to 1.06 cm, d = 1.70, p < 0.001), muscle thickness (NHE: 0.11 cm, 95%CI 0.01 to 0.21 cm, d = 0.51, p = 0.032; ISO: 0.21 cm, 95%CI 0.10 to 0.32 cm, d = 0.86, p = 0.002) and eccentric strength (NHE: 83 N, 95%CI 53 to 114 N, d = 1.79, p < 0.001; ISO: 83 N, 95%CI 17 to 151 N, d = 1.17, p = 0.018). Both groups also finished the intervention weaker isometrically than they started (NHE: -45 N, 95%CI -81 to -8 N, d = -1.03, p = 0.022; ISO: -80 N, 95%CI -104 to -56 N, d = -3.35, p < 0.001). At the end of pre-season the NHE group had improved their 5 m sprint time by 3.3% (±2.0%) and their maximum horizontal velocity was 3% (±2.1) greater than the ISO group who saw no changes. Conclusion Both ISO and NHE training with a periodised sprinting program can increase BFlh fascicle length, thickness, and eccentric strength in Australian Footballers. NHE training also improves 5 m sprint time and maximum velocity. However, both interventions reduced isometric strength. These findings provide unique, contextually relevant insights into the adaptations possible in semi-professional athletes.
