Muscle Activity During Unilateral vs. Bilateral Battle Rope Exercises.
2015
High training intensity is important for efficient strength gains. Although battle rope training is metabolically demanding, no studies have quantified intensity of muscle activity during this type of training. This study analyzes muscle activity during unilateral alternating waves vs. bilateral waves of battle rope training. Twenty-one volunteers participated in a repeated-measures study on 2 different occasions. Surface electromyographic signals were recorded from the anterior deltoid (AD), external oblique (OBLIQ), lumbar erector spinae (LUMB), and gluteus medius (GM) during bilateral waves and unilateral waves and were normalized to the maximum voluntary isometric contraction (MVIC).

Personality differences between academic team sport players and physical education undergraduate students
2020
Background and Study Aim: Although personality research in psychology of sport has a long history, a little is known about the personality of the team sport players among university students. The aim of this study is to investigate differences in personality traits between Team Sport Players (TSP), Physical Education Students (PES) and Other Faculties Students (OFS). Material and Methods: Participants in the cross-sectional study were 441 university students aged between 18 and 34 years old (M = 22.09, SD = 2.19), including 60.09% of men, at a large university in the south of Poland. The NEO-FFI questionnaire was used to assess Big-Five personality traits.

The influence of the stomatognathic system on explosive strength: A pilot study
2015
[Purpose] Recent findings suggest there is an interesting interaction between the stomatognathic system and the musculoskeletal system. The aim of this study was therefore to examine the influence of the temporomandibular joint on the explosive strength of the lower limbs. [Subjects and Methods] An observational study was carried out. The subjects were 60 male football players who voluntarily participated in the investigation. After a warm-up phase of 10 minutes, each participant performed three Squat Jumps (SJ) with different mandible positions: mouth closed and mouth open. SJ heights were recorded using a Sensor Medica force platform and the FreeMed system. [Results] Sixty participants we…
Osgood-Schlatter syndrome and pelvic tilt: longitudinal screening on adolescent male soccer players
2010
Aim and Methods. We realized a longitudinal screening on 258 adolescent male subjects practising agonistic soccer; during sport season, 10.47% of group (N=27) showed a tibial anterior apophysite (Osgood-Schlatter syndrome). Results. By statistical analysis we showed that 77.77% of diseases was related to presence of adolescent pelvic tilt; there more we showed that 83.33% of athletes with right Osgood- Schlatter syndrome presented a left pelvic tilt, 66.67% of athletes with left Osgood Schlatter syndrome showed a right pelvic tilt. Conclusion. The study shows that pelvic tilt can represent a risk factor to controlateral Osgood- Schlatter syndrome inducing a functional overload.
An innovative way to highlight the power of each polymorphism on the elite athletes phenotype expression
2015
The purpose of this study was to determine the probability of soccer players having the best genetic background that could increase performance, evaluating the polymorphism that are considered Performance Enhancing Polymorphism (PEPs) distributed on five genes: PPARα, PPARGC1A, NRF2, ACE e CKMM. Particularly, we investigated how each polymorphism works directly or through another polymorphism to distinguish elite athletes from non-athletic population. Materials And Methods. Sixty professional soccer players (age 22.5 ± 2.2) and sixty healthy volunteers (age 21.2± 2.3) were enrolled. Samples of venous blood was used to prepare genomic DNA. The polymorphic sites were scanned using PCR-RFLP pr…
Mean-Field Game Modeling the Bandwagon Effect with Activation Costs
2015
This paper provides a mean-field game theoretic model of the bandwagon effect in social networks. This effect can be observed whenever individuals tend to align their own opinions to a mainstream opinion. The contribution is threefold. First, we describe the opinion propagation as a mean-field game with local interactions. Second, we establish mean-field equilibrium strategies in the case where the mainstream opinion is constant. Such strategies are shown to have a threshold structure. Third, we extend the use of threshold strategies to the case of time-varying mainstream opinion and study the evolution of the macroscopic system.
Does a specific genetic background influence endurance or power-orientated phenotypes?
2012
The purpose of this study was to determine the probability of individuals having the “best” mitochondrial biogenesis related polygenic profile that could increase performance. We compared polygenic profile analyzing several polymorphisms on sixty professional italian soccer players, considered “power-oriented athletes” and thirty sedentary volunteers. Samples of venous blood were obtained by standard clinical procedures and anticoagulant-treated blood was used to prepare genomic DNA. The polymorphic sites were scanned using PCR-RFLP protocols with different enzyme. Furthermore, a cloted part of venus blood sample was used to obtain serum from which we analyzed total cholesterol, high densit…
Use of Saliva in Alternative to Serum Sampling to Monitor Biomarkers Modifications in Professional Soccer Players
2018
We aimed to investigate the correlation between serum and salivary concentrations of steroid hormones and IgA, and the variation in concentrations of these biomarkers, across a soccer competitive season in a sample of players playing for an Italian major League team. Thirty-five elite male soccer players were recruited and assessed for salivary hormones (cortisol, testosterone, T/C‰ and DHEA-S) and IgA at three different time-points: (t1) after the pre-season period and 16 official matches played; (t2) after a winter break and three official matches played; (t3) 2 days after the final match of the championship and 19 matches played. Players were also tested for blood biomarkers (ser-C, ser-…

STUDY OF GENDER DIFFERENCES IN FUTSAL
2012
The purpose of this study was to evaluate gender differences in futsal male and female professional players with at least three years of sports practice at the federal level. For this reason we analyzed the anthropometric characteristics and athletic performance by standardized agility and speed tests such as: Agility T-test, 20-m Sprint test and shuttle test. We found significant sex and role-related differences in futsal game in agreement with the scientific literature that show a best performance of male soccer players than female ones in Agility T-test, 20-m Sprint test and shuttle test.
