Anthropometric Profile

Background: The anthropometric profile investigation is considered an important parameter to success in sports, however, there is no available study that investigated biometrics parameters in national level teenage players. In this way the aim of this paper was evaluate the anthropometric characteristics of adolescent tennis players by national level. Methods: The anthropometric and body composition evaluation were recognized on 30 adolescents practicing tennis with at least four years. The following parameters were evaluated: body composition, skin folds, perimeter and fat member. Results: The adolescent tennis players presented eutrophication status according to the mean BMI (kg/m 2 ) and values ​​within normality in relation to the percentage of fat (%). Conclusion: The results of the present study resembled the findings of literature on the anthropometric characteristics of amateur and professional tennis players.

The Mean

This paper examines the gender wage gap in professional sports using a pooled cross-section of professional tennis players across the years 2011-2017. The dependent variable is the prize money earned by the top fifty male and top fifty female ranked tennis players throughout the world. This prize money is measured in 2017 real dollar value. The independent variables include: number of tournaments played, age, rank differentiation, gender, country and WTA/ATP score. Gender inequality is measured by determining the wage gap shown through the mean prize money earned by the professional tennis players from 2011-2017. While prize money for men and women has recently become equal in the Grand Slam tournaments, there is evidence to show that women's prize money is considerably lower in the less-publicized tournaments. Results of the ordinary least squares (OLS) regressions suggest that there is evidence for a gender-related pay disparity in professional tennis due to a number of statistically significant variables including WTA/ATP score (+), age (+), country (+) and the gender (-) and year (+) dummies.

Contemporary anthropological research confirms the fact that body composition is one of the basic elements differentiating athletes from persons not practising sport. Among athletes representing various branches of sport there are also significant differences in their body composition. Internal proportions of the body composition of an athlete, or a selected group of athletes, is an especially important yet little researched issue of sports anthropology. This problem is still topical in sports games, especially in tennis. Therefore, the aim of the study was to determine internal proportions of the body composition of female tennis players from the Polish national team in comparison to persons who do not practice sport professionally. The study involved female athletes of the Polish national tennis team (n = 10). The study was carried out in a training camp from 28 September to 9 October 2002 in Zakopane — Centre of Sports Preparation. Athletes’ age was 16—20 (18.1 ± 1.4) years, and the training experience 8—12 years (10.5 ± 1.8). The mean body height for the group members was 171.9 ± 6.7 cm and the mean body mass 59.7 ± 6.3 kg. The results of research by Piechaczek et al. (1996) constituted the reference point for the results of measurements of Polish tennis representatives. The authors studied 153 female students of Warsaw Technical University aged 20.2 ± 1.09 years. They were randomly chosen students of the first and the second year of various departments at this university. The mean body height of the students was 166.2 ± 6.2 cm and the mean body mass 57.4 ± 7.72 kg. Anthropometric measurements were taken using standard instruments (Drozdowski, 1998). The analysis involved 11 somatic features which determined three so-called factors of body composition: length (m1), stoutness (m2) and obesity (m3). The assessment of proportions of the body composition was made by means of Perkal’s natural indices (1953) with Milicerowa’s modifications (1956). We determined the following: composition factors (m), index of total body size (M), internal proportions of the body composition, evenness of composition, the code of internal proportions; also the assessment of internal proportions of the body composition within each of the factors.Taking into consideration the mean values of the studied somatic features in the control group and the comparative group we found differences in their body composition. The representatives of the Polish national tennis team showed substantially longer upper and lower limbs, and the body height was greater. They also had much greater forearm perimeter and shorter pelvic width. As to the total body size, the tennis players slightly exceeded the students (M = 0.24). The total body size (M) resulted from high values of length features (m1 = 1.01), low ones of stoutness (m2 = –0.39) and medium ones of obesity (m3 = 0.1). The value of the intragroup variability index (harmony of composition) amounted to 1.4 and the code of internal proportions of tennis players’ body composition — to 6—2—4. The proportions of internal features of the stoutness index (natural indices of features within a factor) showed the advantage of the forearm perimeter (1.62) and elbow width (0.36). The knee width (–1.30) and pelvic width (–0.60) were disproportionate to the total value of this factor. The input of features characterizing the length factor was relatively proportional.Keywords: tennis, training, body composition, internal proportions.

Anthropometric Profile

Profiling of beach handball players is required to optimize sports performance, talent identification, and injury prevention. The study aimed to describe the anthropometric characteristics, somatotype, and body composition of elite male and female beach handball players classified by playing positions. Thirty elite beach handball players (15 male, 15 female) of the Spanish National Beach Handball Team, which ranked fifth and first in the VII World Championships, respectively, were categorized as front (wings/specialists), back (pivots/defenders) players and goalkeepers. Independent from position, male players showed larger values of anthropometric characteristics, girths, breadths, and absolute components of body composition than female players. Contrastingly, skinfolds, and body fat mass percentage were higher in female players. All these results were statistically significant (p < 0.05) with large to extremely large effect sizes (d = 1.4–5.4). The position-related differences indicated that male back players were taller (p = 0.008; ηp2 = 0.56), heavier (p = 0.016; ηp2 = 0.50) and showed larger arm span (p = 0.036; ηp2 = 0.42) than front players. In contrast, female goalkeepers showed larger body mass (p = 0.007; ηp2 = 0.57) and BMI (p = 0.035; ηp2 = 0.43), whereas back players showed higher muscular mass than goalkeepers (p = 0.022; ηp2 = 0.47). The present study provides anthropometric reference values of elite beach handball players, and indicates differences between playing positions, providing normative data for talent identification of male and female players.

Anthropometric Profile

The anthropometric profile has a fundamental role in rowing performance and young talent detection. The objective of this study was to analyze the anthropometric profile, body composition, and somatotype in traditional rowers, and to analyze which variables can be used as predictors of rowing performance. Twenty-four rowers competing at national level participated in this study, thirteen men and eleven women. Significant differences (p < 0.001) were observed in the height of male rowers (large effect size, d = 1.8) and in body mass (very large effect size, d = 2.4). Also, muscle mass reached a higher percentage in male rowers (d = 3.7), whereas the sum of seven skinfolds (d = 2.0) and body fat percentage (d = 2.0) reached higher values in female rowers, all their difference being significant (p < 0.001) with very large effect size. The somatotype of male rowers was ecto-mesomorph (1.8-4.5-3.0), and the somatotype of female rowers was in the balanced mesomorph (2.8-3.8-2.6). A very strong correlation between height (r = 0.75; p = 0.002) and rowing performance was found in male rowers. Body mass (r = 0.70; p = 0.009) and muscle mass (r = 0.83; p = 0.001) showed also very strong correlation in female rowers. Finally, height was the best predictor of performance for male rowers (R2 = 0.56, p < 0.003) and muscle mass for female rowers (R2 = 0.68, p < 0.002). The anthropometric profile of male and female traditional rowers showed differences to be considered in training programs and talent selection.

Background: Os acromiale is a rare condition mostly reported in the literature through case reports, imaging studies, or reports of surgical treatment. This condition is the result of nonunion of growth plates of the acromion during the natural developmental process that occurs between 15 and 25 years of age. Its incidence is low, and few studies are available in the literature on athletes with high functional demands, and particularly on athletes within a specific sport. Purpose: To collect epidemiological data and to report the amount of time out of play as well as the type of treatment and its efficiency in professional tennis players. Study Design: Case series; Level of evidence, 4. Methods: We performed a retrospective study using the medical data of athletes within our national tennis league who complained about their shoulder between 2011 and 2016. Nine professional tennis players (mean age, 20 years) with painful shoulders were diagnosed with os acromiale; 3 of them played at an international level, with the other 6 playing at a national level. The diagnosis was confirmed using radiography, including the axillary view, and magnetic resonance imaging (MRI). One female player had associated subacromial bursitis. Results: All cases of os acromiale were classified as involving the mesoacromion, following the Lieberson classification. No patient underwent surgery, and no patient was treated with local or subacromial infiltration. Patients stopped competition and training throughout the rehabilitation period. All patients received medical treatment with nonsteroidal anti-inflammatory drugs (NSAIDs), ice, and physical therapy with a specific rehabilitation program. All athletes returned to their former level of play after a mean of 37 days. No patient suffered from recurrent pain. One patient underwent MRI after 2 years, showing a normal bone signal and complete healing of the acromion. Conclusion: Conservative treatment including NSAIDs, rest, ice, and physical therapy allowed for good recovery and return to the former level of play. Surgical treatment is usually not indicated for os acromiale in the professional tennis player.

Anthropometric Characteristics

Introduction. Anthropometric and anaerobic profile of elite athletes are fundamental for the assessment of their respective performance. The present study was designed to evaluate the anthropometric parameters, body composition and anaerobic characteristics of elite male handball players and rowers, and to compare them in relation to specific sport demands. Material and Methods. The study group consisted of 41 elite national level athletes: 20 handball players (aged 23.7?3.72) and 21 rowers (aged 19.7?2.84). Anthropometric characteristics (body mass, body height, skinfold thickness, body circumferences), and body fat mass were evaluated, and Wingate anaerobic test for anaerobic power assessment was applied. Results. The significant differences were noted in chest, upper arm, waist and hip circumferences, and supraspinal and calf skinfolds between the two investigated groups. Rowers showed higher values of fat body mass (13.2?3.76 vs. 10.7?3.76%), but lower body mass index (22.0?1,92 vs. 25.7?2.31 kg/m2) compared to handball players. When analyzing the Wingate test parameters, significantly higher values of absolute anaerobic power (786?127 vs. 691?140 W), absolute explosive power in the handball players compared to the rowers were recorded (118?26.3 vs. 105?27.8 W/s), while rowers achieved higher relative anaerobic capacity (192?31.2 vs. 177?20.8 J/kg). Conclusion. Specific body composition and anthropometrical assessment as a part of morphological analysis should complement physiological profile of elite athletes. The analysis of the anaerobic performance shows that the handball players have greater alactic anaerobic and explosive power component, compared to the rowers in whom the anaerobic endurance and specific training have the greatest effect on the consumption of dominant metabolic substrate during the race.
