Professional soccer players with functional asymmetries possess a higher risk of sustaining hamstring strains. Previous injury seems not to constitute a risk factor. The systematic isokinetic evaluation of the lower extremities during the preseason period can provide therapists and trainers with valuable data regarding the predictive elements of non-contact hamstring strains in professional soccer players.

Functional strength asymmetries of the ankle flexors and increased body mass index and body weight raise the propensity for ankle sprains in professional soccer players. Age and asymmetries in ankle laxity are potential factors worth revisiting, as there was an indication for younger players and players with ankle instability to be at higher risk for ankle injury. Proper preseason evaluation may improve prevention strategies for this type of injury in soccer.

[Purpose] This study was aimed to investigate the effects of Ergon ® IASTM applications on the upper or lower part of the Superficial Back Line (SBL) on the hamstring’s flexibility. [Participants and Methods] Sixty University students (age=24.4 ± 4.39; height=176.78 ± 8.31 cm; weight=75.16 ± 11.21 kg) were randomly divided into three sub-groups and received a single 15-minute treatment with Ergon ® Technique in a) the upper and b) the lower part of SBL or c) served as control. The participants received one treatment per week for four weeks with a simultaneous pre-and post-therapy assessment of their hamstrings flexibility using the passive Straight Leg Raising (SLR). [Results] Both experimental groups improved SLR performance from pre to post during the four weeks from 4.4% to 9.2% in the trunk group and from 4.9% to 8.0% in the lower body group. These differences were significantly greater from the CTRL group. No differences were observed between the two experimental groups. [Conclusion] In conclusion, application of Ergon Technique of either the upper or lower part of the SBL may lead to a significant increase in the hamstring flexibility irrespective of the site of application.

This study was aimed to compare the effects of three soft tissue treatments in different parts of the myofascial lateral line (LL) on the hip adduction range of motion (ROM). [Participants and Methods] Thirty university students received Ergon ® instrument-assisted soft tissue mobilization (IASTM) treatment, foam rolling, and static stretching on the upper or lower part of the LL on the side of their non-dominant lower limb, while the other body side served as control. The participants received one treatment per week for six weeks with a simultaneous pre-and post-therapy assessment of their hip adduction ROM. [Results] The hip adduction ROM was improved on the intervention side in all experimental groups. The gains were more significant in groups that received the Ergon treatment. All Ergon interventions, as well as foam rolling on the upper part of the LL, led to the greatest hip adduction ROM improvement compared to the control side. No differences were observed between the Ergon groups. [Conclusion] The findings suggest that the implementation of Ergon IASTM, foam rolling, and stretching can produce positive effects on the hip ROM. The Ergon Technique is more effective compared to foam rolling and stretching, irrespective of the application site.

Physical parameters were amongst the most prevalent characteristics of the Greek sample, thus offering a direction towards a more targeted treatment and rehabilitation planning. Unlike previous literature, most sociodemographic characteristics were not correlated with any LBP physical or lifestyle factors, thus possibly indicating a different socioeconomic background and aetiology domain to that of the usual non-specific LBP spectrum.

[Purpose] The purpose of this preliminary study was to investigate whether young players with no history of injury, have developed early asymmetries in dynamic balance ability tested via the recommended for screening in sports, Modified Star Excursion Balance Test (MSEBT). [Participants and Methods] Twenty-four young healthy male soccer players participated in the study having at least 4 years of systematic soccer training. The Waterloo Footedness Questionnaire was used to discriminate the stability dominant leg (STAB) from the non-stability dominant leg (NSTAB). Dynamic balance was assessed via the MSEBT. Participants, after familiarization, made 3 attempts in each direction for both legs: a) Anterior (AN), b) Posterolateral (PL) and c) Posteromedial (PM). [Results] The sole statistically significant performance asymmetry was in the PL direction, in favor of the STAB (94.5 ± 13.3 cm vs. 98.1 ± 10.4 cm). [Conclusion] The results of this pilot study showed a potential for developing dynamic balance asymmetries, in soccer players at the age of 13–14 years. Since asymmetry was significant in only one direction, further long term monitoring would be helpful to evaluate whether this is a growing functional deficit, potentially involving any of the other two directions of testing or if it is alleviated with increasing training age. These asymmetries could comprise an injury risk factor.

Context: Instrument-assisted soft tissue mobilization (IASTM), tissue flossing, and kinesiology taping are increasingly popular treatments among athletes for improving functional performance, despite limited evidence for their efficacy. Objective: Previous research regarding the efficacy of soft tissues and neuromuscular techniques on improving functional capacity of shoulder joints in athletes has yielded conflicting results. We examined the immediate and short-term effects of IASTM, flossing, and kinesiology taping on the functional capacities of amateur athletes’ shoulders. Design: Randomized controlled study. Setting: Clinical assessment laboratory. Participants: Eighty amateur overhead athletes (mean [SD]: age = 23.03 [1.89]; weight = 78.36 [5.32]; height = 1.77 [.11]). Interventions: We randomly assigned participants to 4 research sub-groups in which they received the following treatments on their dominant shoulders: IASTM (n = 20), flossing (n = 20), both IASTM and flossing (n = 20), and kinesiology tape (n = 20). Nondominant shoulders served as controls. Main Outcome Measure: We evaluated participants—before, immediately after, and 45 minutes after the therapeutic interventions—with the following tests: internal and external shoulder rotation range of motion, isokinetic strength and total work, the functional throwing performance index, and the one-arm seated shot put throw performance. Results: All therapeutic interventions significantly improved the strength and functional performance of the dominant shoulder in comparison with the control (P < .005) immediately after and 45 minutes after the treatment. The IASTM led to significantly greater improvement in shoulder internal rotation than kinesiology taping immediately after (P = .049) and 45 minutes after the treatment (P = .049). We observed no significant differences between the other treatment interventions (P > .05). Conclusion: Findings from the current study support the use of novel soft tissue and neuromuscular techniques for the immediate and short-term improvement of the shoulder functional capacities in amateur overhead athletes.
