The anthropometric characteristics are decisive for an optimal physical level and, therefore, a good level in the game; and they can be different depending on the game position.
The aim of this study was to identify the physical characteristics, body composition and somatotype of professional soccer players and to verify differences according to their playing positions: goalkeepers, defenders, forwards and midfielders.
The measurements were performed on 57 male players of a soccer team of the Spanish Football League One. Twenty seven anthropometric variables were measured (height and body weight, four bone breadths, eleven girths and ten skinfolds) and the Bioelectrical Impedance Analysis was also performed. The percentage of body fat has been determined from 11 different equations.
Goalkeepers showed the highest weight (80.2 ± 3.2 kg), supraespinal (10.5 ± 3.8 mm) and abdominal (15.6 ± 3.5 mm) skinfolds than others positions. In relation to body fat percentages, similar results were obtained from the equations of Jackson-Pollock (from 3 and 7 skinfolds), Carter, Withers, and Heyward and Stolarczyk (mean value 7.8 ± 1.5%). Higher results were obtained from the other equations applied. Differences among positions were also found concerning body composition; goalkeepers showed the highest body fat percentage (9.4 ± 1.4%). Mean somatotype was also different among positions; goalkeepers and forwards presented a balanced mesomorph somatotype while defenders and midfielders showed an ecto-mesomorph one.
The differences in morphological characteristics according to the team position were notice only in goalkeepers, especially regarding their weight, abdominal and supraespinale skinfolds and the percentage of fat tissue.
Patellofemoral pain syndrome is common among athletes who participate in jumping, running and pivoting sports. The aim of this study was to compare selected lower limb biomechanical variables between University of Ibadan students (athletes) with and without patellofemoral pain syndrome.
The research design for this study was a case control survey and a purposive sampling technique was used to recruit participants. Two hundred and twenty two (191(85.8%) males and 31 (14.2%) females) sportsmen participated in this study. The participants’ age was between 20-29 years. Fourty sportsmen tested positive to Clarke’s test while 27 sportsmen tested positive to Eccentric step test. Measurements of static quadriceps angle, hamstring tightness and navicular height were taken for all participants.
Data were analyzed using descriptive statistics of mean, standard deviation, percentages and inferential statistics of Independent ‘t’ test.
The mean lower limb biomechanical variables of participants with patellofemoral pain syndrome were 13.18 ± 2.37°, 106.46 ± 16.11° and 1.21 ± 0.61 cm while those without were 13.65 ± 2.46°, 128.95 ± 25.36° and 1.03 ± 0.58 cm for static quadriceps angle, hamstring tightness and navicular height respectively. There was no significant difference (p > 0.05) in selected lower limb biomechanical variables between participants with and without patellofemoral pain syndrome.
In conclusion there was no significant difference in static quadriceps angle, hamstring tightness and ankle pronation between participants with and without patellofemoral pain syndrome. It was recommended that PFPS development is probably multifactorial with other functional disorders of the lower extremity apart from the selected variables.
Context: Shoulder pain is one of the most frequent reported complaints in intensive competitive swimming. The so-called ‘swimmers’ shoulder’ has been widely explored and has been reported sometimes without specific reference to contributing mechanisms or structures. Somatic dysfunction is defined as an impaired or altered function of related components of the somatic system and may appear in the early stage of pain feeling.
Aim: To evaluate somatic dysfunctions in a group of young competitive swimmers with and without shoulder pain and its relationship with the shoulder’s mobility along with the efficacy of an osteopathic manipulative treatment (OMT) on shoulder’s mobility, pain, and comfort of swimming.
Material and method: 20 competitive swimmers (14.6 ± 1.3 ys; 11.6 ± 2.4 hs.wk-1) were divided into two groups, with and without shoulder pain (SPG/CG). Before and after light touch/OMT, and 1 week later, somatic dysfunctions, shoulder’s range of mobility, pain, and swimming comfort were assessed by 2 independent osteopaths.
Results: Somatic dysfunctions were observed in both groups without significant differences in the number or localization and were independent of severity of pain. In the SPG, pain decreased significantly after OMT (6.1 ± 1.9 vs. 3.9 ± 1.8; p = 0.001) and remained stable 1-week later (P = NS). Shoulder’s mobility was lower on the aching shoulder in the “shoulder pain” group when compared to the control group on flexion and abduction tests but not on extension or adduction tests. Following OMT, only abduction improved when compared to light touch. Comfort in swimming was reported as “better” in both OMT/light touch groups.
Conclusion: There is no difference between light touch and OMT as both decreased pain and increased comfort in swimming but abduction range of motion only improved in the OMT group.
Through cultural consciousness, the characteristics of traditional Chinese sports culture in the new period are analyzed and studied, and the traditional Chinese sports culture in the new period has the following six characteristics: 1. Sports social model of “etiquette” 2. Sports personality model of the gentleman’s way; 3. The sports behavior mode of the golden mean; 4.

The aim of the paper is to determine the effects of physiotherapy and rehabilitation (PHTR) on a child with Pallister-Killian Syndrome (PKS). Gross Motor Function Measure (GMFM) and duration of grasping ping pong ball were the primary outcome measures which were conducted at the beginning, 12th, and 24th month. Neurodevelopmental Therapy and Sensory Integration Therapy were used as intervention methods. The most increase with around 50% was acquired in Section A of the GMFM. Duration of holding a ping pong ball gradually increased. As a result, this is the first paper presenting a PHTR shedule and its results in a child with PKS.
Purpose: The benefits of Physical Activity (PA) considered as a major supportive care in cancer patients, on survival, and recurrence risk is largely disseminated in public communication. However, these data must be taken with caution. The main objectives were to review the evidence and limits of studies reported regarding the post-diagnosis PA role on cancer survival and recurrence risk to secondly discuss of research perspectives on PA programs.
Method: The narrative review included all published or ongoing studies in English during the last 20 years related to PA, survival and recurrence risk with a systematic search on main databases.
Results and discussion: The current evidences regarding the PA role on survival and recurrence risk were only based on cohort studies, mainly in breast cancer. The major methodological limits identified as the lack of PA change assessment, PA level assessed largely by self-reported methods and the significant inter- but also intra- variability make the interpretation of data very. Beyond the use of rigorous RCT, the major issue is to develop adapted and personalized interventions to progressively increase PA level overtime in cancer survivors.
Conclusion: Despite the lack of causal relationship between post-diagnosis PA, survival and recurrence risk, the review underlines several interesting research perspectives. The future PA interventions, using innovative tools and integrated to the “real-life” will argued for the potential antitumoral PA role growing in literature.
Sustained isometric contractions of skeletal muscles produce intramuscular pressures that leads to blood flow restriction. In result an active muscle feels deficit of oxygen what bring to muscle fatigue. In another side during exercise we have physiological contradiction between raising of oxygen demand by working muscle and restriction of blood flow due to vessel pressing. To clarify this issue many research has been performed based mainly on measurement of blood flow in muscle tissue. The purpose of this study was to assess real-time changes in muscle oxygenation during a sustained isometric contractions of dorsiflexor muscle of low (30%), moderate (60%) and submaximal (90%) intensity. Experiments were conducted using the subject’s dominant (right) leg. Volunteers was recruited from eight male students of USIPC (age: 19±2 years, weight: 75±6 kg). Tissue oxygenation index (StO2) were recorded from the tibialis anterior using NIRS device (NONIN). Saturation was higher at 30% compared with both 60% and 90% MVC at all time points after start exercise and higher at 60% than 90%. Oxygen consumption (VO2) permanently increased from slow (30%) to moderate (60%) and submaximal contractions. After cessation of the each contraction there was a large and immediate hyperemic response. Rate of StO2 increasing after effort cessation what reflects the resaturation of hemoglobin which depend on integrity and functionality of vascular system and reflects blood vessel vasodilation. StO2 restoration rate permanently increased from slow (30%) to moderate (60%) and submaximal contractions too. At last on final stage of experiment arterial occlusion test has been performed to determine the minimal oxygen saturation value in the dorsiflexors. Oxygen saturation reached a 24±1.77% what is significantly higher than StO2 after 60 and 90%MVC.
So, we can conclude that oxygen saturation at 60% and 90% MVC are similar and sharply decreased after start of exercise. It means that after 60% MVC take place occlusion of blood vessels due to intramuscular pressure. Oxygen consumption of active muscle increased depend on intensity of exertion according to increasing of oxygen demand. StO2 resaturation rate (Re) permanently increased from slow (30%) to moderate (60%) and to submaximal contractions. Re increasing after effort cessation reflects the resaturation of hemoglobin which depend on integrity and functionality of vascular system and reflects blood vessel vasodilation.
Purpose: Here, we report the complications of endoprosthesis with threaded cups according to our application in cases of complicated acetabulum (hip revisions and femoroacetabular impingement (FAI)).
Methods: A total of 504 patients was analyzed, including 189 men and 315 women. For re-implanted patients (n = 49), the mean time to re-implantation was 6.3 years and the average age at re-implantation was 54.7 years. For censored patients (n = 455), the mean time to censoring was 5.5 years and the average age of the implant was 55.7 years. Among the patients that were censored, 77 died and 378 patients did not experience an event necessitating re-implantation.
Results: For the total study population, the Kaplan-Meier estimate of 5 year survival is 0.94 and of 10 year survival is 0.85. 90% of the implants survived 7 years, 80% of the implants survived almost 12 years and 70% of implants survived almost 15 years. Kaplan-Meier survival analysis suggests that men have higher survival than women. Age of the patient at the time of implant was not a statistically significant factor for re-implantation (p value = 0.21) but sex was (p value = 0.02). Women had 2.25 times more risk of being re-implanted than men.
Conclusions: In our case series, the failure rate, as a result of aseptic loosening, was 7.4% (n = 51). More than half the failure cases (56%) required re-implantation. Over one-third (37%) of the primary arthrosis cases, were found to be FAI, lessening the frequency of diagnosis of the former. In our clinic, the threaded cup seems to be indispensable in hip revision surgery and in treating FAI.
Badminton is a sport that requires a player to perform while being still, as well as in motion. Stability is the ability to maintain or control joint movement or joint position, in the static as well as dynamic state. Improvement in stability could help maintain body control and proper posture positions during play. Accordingly, the study was proposed to analyze stability in junior badminton players and understand its importance. A total of 106 players from South Asia between the ages of 8 and 15 years were analyzed. Prokin 252N and Balance trunk MF systems of Tecnobody Italy were used in the assessment and static, dynamic, and pelvic stability was recorded. The variables used were gender, age, body mass index, and experience in years, level at which they play, current pain, and clicks & catches in the past 1 year. Our study showed that there was significant difference in pelvic stability in terms of age and level at which players compete. There were a variety of other factors which do not affect stability. There needs to be a greater focus on stability training as part of the development of junior badminton players.
The effect of weekly physical activity on biological age (BA) parameters, we have conducted a study 215 females from 17 to 18 years old who were divided into the experimental (EG, n=105) and control (CG, n=110) groups. It was established that if at the end of the experiment the BA parameters of the females CG weren’t a significantly different from the average data (p>0.05), then there was a statistically significant decrease in the BA parameters of the females EG. This was confirmed by statistical probability (p<0.01), which suggests the dependence of biological age parameters on the extent of weekly physical activity.
