“…20 With regards to this, a recent meta-analysis showed a strong association between the 577RR genotype and power athletic performance especially among Europeans, regardless of the significant heterogeneity among the groups of athletes. 15 Team sports are intermittent in nature and require the repetition of powerful movements including short-distance sprinting and jumping, 21 and these actions require the working muscles to produce force at a high velocity. 22 We therefore hypothesised that the 577RR genotype frequency distribution would be higher in team-sport athletes compared to the control group.…”

a b s t r a c tObjectives: To determine the association between the ␣-actinin-3 (ACTN3) R577X polymorphism and elite team-sport athletic status in three cohorts of European team-sport athletes. Design: We compared the genotype and allele frequencies of the ACTN3 R577X (rs1815739) polymorphisms between team-sport athletes (n = 205), endurance athletes (n = 305), sprint/power athletes (n = 378), and non-athletic controls (n = 568) from Poland, Russia and Spain; all participants were unrelated European men. Methods: Genomic DNA was extracted from either buccal epithelium or peripheral blood using a standard protocol. Genotyping was performed using several methods, and the results were replicated following recent recommendations for genotype-phenotype association studies. Results: Genotype distributions of all control and athletic groups met Hardy-Weinberg equilibrium (all p > 0.05). Team-sport athletes were less likely to have the 577RR genotype compared to the 577XX genotype than sprint/power athletes [odds ratio: 0.58, 95% confidence interval: 0.34-0.39, p = 0.045]. However, the ACTN3 R577X polymorphism was not associated with team-sports athletic status, compared to endurance athletes and non-athletic controls. Furthermore, no association was observed for any of the genotypes with respect to the level of competition (elite vs. national level). Conclusions: The ACTN3 R577X polymorphism was not associated with team-sport athletic status, compared to endurance athletes and non-athletic controls, and the observation that the 577RR genotype is overrepresented in power/sprint athletes compared with team-sport athletes needs to be confirmed in future studies.

“…Interventions designed to improve CODS are therefore likely to carry a beneficial effect to performance. Acute pre-conditioning interventions employing heavy resistance exercise (41) and loaded ballistic exercise (i.e. weight vest loaded warm-up) (22,27) have been demonstrated to favourably affect CODS although the reasons behind these performance enhancements are yet to be elucidated.…”

It has previously been shown that pre-conditioning interventions can augment change of direction speed (CODS). However, the mechanistic nature of these augmentations has not been well considered. The current study sought to determine the effects of pre-conditioning interventions designed to augment vertical stiffness on CODS.Following familiarization, ten healthy males (age: 22 ± 2 years; height: 1.78 ± 0.05 m; body mass: 75.1 ± 8.7 kg) performed three different stiffness interventions in a randomized and counterbalanced order. The interventions were: a) bilateral-focused, b) unilateral-focused, and c) a control of CODS test practice. Vertical stiffness and joint stiffness was determined pre-and post-intervention using a single leg drop jump task. CODS test performance was assessed post-intervention using a double 90 o cutting task. Performances following the unilateral intervention were significantly faster than control (1.7%; P = 0.011; d = -1.08), but not significantly faster than the bilateral intervention (1.0% faster; P = 0.14; d = -0.59). Versus control, vertical stiffness was 14% greater (P = 0.049; d = 0.39) following the unilateral intervention and 11% greater (P = 0.019; d = 0.31) following the bilateral intervention; there was no difference between unilateral and bilateral interventions (P = 0.94; d = -0.08). The findings of the current study suggest that unilateral pre-conditioning interventions designed to augment vertical stiffness improve CODS within this experimental cohort.

“…For example, Zois et al (2011) observed that the height of the vertical jump improved by +2 % after intensive neuromuscular activation using 5 RM (repetition maximum) on the legpress. The objective of this research was to investigate the immediate effect of the neuromuscular activation of knee extensors (via the electrostimulation method) on the performance in the vertical jump.…”

Bílý, J. & Cacek, J. (2014). Effect of the neuromuscular activation of knee extensors on vertical jump by using electrostimulation method. J. Hum. Sport Exerc., 9(Proc1), pp.S512-S518. Neuromuscular electrical stimulation is one of the methods of strength development during which there is no voluntary muscle contraction. The aim of this study was to investigate the influence of the neuromuscular activation of knee extensors on vertical jump by using electrostimulation method. Ten healthy trained male students in sportssciences, aged 21-25 years, perform Sargent jump test. They perform two kinds of jump -squat jump and drop jump (42 cm heigh bench) immediately after electrostimulation and without electrostimulation. Both kinds of jump were performed with and without dynamic stretching. The subjects received electrostimulation for 2 minutes with preset program Explosive power on electrostimulator. We found no significant difference in measuring of heigh of squat jump, where neuromuscular activation by using electrostimulation method was or was not applied. The results showed that heigh of drop jumps significantly increased by using electrostimulation method +2,7 % (p = 0.005) with dynamic stretching and +3,3 % (p = 0.018) without stretching. The results showed that neuromuscular activation by using electrostimulation method (immediately before performance) can have positive effect on heigh of drop jump and so can be added to warm-up part before performance. Using electrostimulation method had no significant effect on squat jump performance.
