Criterion-related validity of four clinical tests used to measure hamstring flexibility in professional futsal players

Objective

To examine the criterion related validity of the sit-and-reach test (SR), toe touch test (TT), modified sit-and-reach test (MSR) and back-saver sit-and-reach test (BSSR) for estimating hamstring flexibility measured through the passive straight leg raise test (PSLR) in professional futsal players.

Design

Correlation laboratory study.

Setting

Controlled laboratory environment.

Participants

One hundred and three futsal players (55 males age 26 ± 4 years, 48 females age 23 ± 5 years).

Main outcome measures

Two trials of SR, TT, MSR, BSSR (left and right) and PSLR right and left (hamstring criterion measure) in a randomized order.

Results

Regression analysis was performed to examine the association of SR, TT, MSR and BSSR with PSLR in both males and females separately. In males, only MSR test had moderate association criterion with PSLR (R² = 0.57). In females, SR (R² = 0.86), TT (R² = 0.85), MSR (R² = 0.53) and average BSSR (R² = 0.82) were associated with PSLR.

Conclusions

SR, TT, MSR and BSSR had moderate criterion related validity for estimating hamstring flexibility in female but not male professional futsal players. The authors recommend that researchers, clinicians, and physical therapists adopt one angular test as a measure of hamstring muscle length in futsal players.     

Intra-individual, randomised comparison of the MRI contrast agents gadobutrol and gadoterate in imaging the distal lower limb of patients with known or suspected osteomyelitis, evaluated in an off-site blinded read

Hepatic arterial chemoembolization using drug-eluting beads in gastrointestinal neuroendocrine tumor metastatic to the liver

Évolution chez l'homme de l'Insulin-Like Growth Factor-I dans le liquide interstitiel musculaire suite à un exercice en résistance

Introduction

The impact of resistance exercise on the growth of the vastus lateralis was assessed through interstitial microdialysis measurement of free Insulin-like Growth Factor-I at +3 h30, +4 h50 and +6 h after exercise in 4 healthy subjects.

Results

We observed 3 h30 after exercise an interstitial increase in 3 over 4 subjects, and thereafter a progressive decrease. In the mean time, free or total plasma concentrations did not change.

Conclusion

Resistance exercise seemed to induce an early increase of muscle interstitial free Insulin-like Growth Factor-I in order to initiate muscle growth by an autocrine – paracrine way.

Relation entre le five-jump test, l'épreuve de vitesse sur 30 m et la détente verticale

Aim

To study the relationship between the five-jump test (5JT) performance, 30 m sprint test and vertical jump performances.

Synthesis of facts

Thirteen male soccer players (15–16 years olds) performed the following tests: 5JT, 30 m sprint and 3 vertical jumps: SJ, CMJ and Free CMJ. The 5JT was strongly correlated with 30 m sprint (R = 0.83; P < 0.01), the SJ (R = 0.71; P < 0.01), the CMJ (R = 0.84; P < 0.01) and the free CMJ (R = 0.62; P < 0.05). The 5JT is also correlated with the index of explosiveness (R = 0.93; P < 0.01).

Conclusion

The 5JT can be used to evaluate muscular strength and explosivity of lower limbs in young soccer players.
