The Relationship

The purpose of the present study was to investigate the relationship between body composition, anaerobic performance and sprint performance of amputee soccer players. Fifteen amputee soccer players participated in this study voluntarily. Subjects’ height, body weight, body mass index, body fat percentage (Jackson and Pollock formula) and somatotype characteristics (Heath-Carter system) were determined. The sprint performance at 10m, 20m and 30m was evaluated, whereas the counter movement jump (CMJ), relative CMJ (RCMJ), squat jump (SJ) and relative SJ (RSJ) tests were used for the determination of anaerobic performance. The results of the Pearson Product Moment correlation analysis indicated that body composition was significantly correlated with CMJ and SJ (p < 0.01), on the other hand, no measure of body composition was significantly related to the other component (p > 0.05). A significant correlation was found between CMJ, RCMJ, SJ, 10 m, 20 m and 30 m sprint performance (p < 0.05); whereas, in contrast, no measure of body composition was significantly related to the 10 m, 20 m and 30 m sprint performance (p > 0.05). In conclusion, the findings of the present study indicated that sprint performance was described as an essential factor in anaerobic performance whereas body composition and somatotype play a determinant role in anaerobic and sprint performance in amputee soccer players.

Before And After

The aim of the study was to determine the effects of short-term (4 weeks, twice a week: 8 sessions) plyometric training on agility, jump, and repeated sprint performance in female soccer players. The study comprised 17 females performing this sports discipline. The players were randomly divided into two groups: with plyometric training (PLY) and the control (CON). All players followed the same training program, but the PLY group also performed plyometric exercises. Tests used to evaluate physical performance were carried out immediately before and after PLY. After implementing the short PLY training, significant improvement in jump performance (squat jump: p = 0.04, ES = 0.48, countermovement jump: p = 0.009, ES = 0.42) and agility (p = 0.003, ES = 0.7) was noted in the PLY group. In the CON group, no significant (p > 0.05) changes in physical performance were observed. In contrast, PLY did not improve repeated sprint performance (p > 0.05) among female soccer players. In our research, it was shown that PLY can also be effective when performed for only 4 weeks instead of the 6–12 weeks typically applied.

The Relationship

Background:The purpose of this study was to assess the relationship between intensity of physical activity (PA) and body composition in 343 young women.Methods:Physical activity was objectively measured using accelerometers worn for 7 days in women 17 to 25 years. Body composition was assessed using the BOD POD.Results:Young women who spent less than 30 minutes a week performing vigorous PA had significantly higher body fat percentages than women who performed more than 30 minutes of vigorous PA per week (F = 4.54, P = .0113). Young women who spent less than 30 minutes per day in moderate to vigorous PA (MVPA) had significantly higher body fat percentages than those who obtained more than 30 minutes per day of MVPA (F = 7.47, P = .0066). Accumulating more than 90 minutes of MVPA per day was associated with the lowest percent body fat. For every 10 minutes spent in MVPA per day, the odds of having a body fat percentage above 32% decreased by 29% (P = .0002).Conclusion:Vigorous PA and MVPA are associated with lower adiposity. Young women should be encouraged to accumulate at least 30 minutes of MVPA per day, however getting more than 90 minutes a day is predictive of even lower levels of adiposity.

The Relationship

2D:4D ratio is determined by balance between androgens and estrogens. Low level estrogen reduces bone mineral density (BMD) and incurs negative changes to bone microarchitecture, increasing the risk of osteoporosis and, as a consequence, fracture risk in women. The purpose of this study was to investigate the relationship between 2D:4D, muscle strength and body composition to BMD in young women. One hundred twenty-seven young women (age range 24-36 years) voluntarily participated in this study. Lengths of the second (index) and fourth (ring) fingers, upper and lower body strength and body composition (body mass index, BMI; waist to hip ratio, WHR) and body fat percentage were estimated. Also, blood levels of calcium and 25-hydroxyvitamin D (25OHD) were evaluated and dual-energy X-ray absorptiometry device was used to measure BMD in the lumbar spine (LS) and femoral neck (FN). The results showed that digit ratios, upper body and lower body muscle strength, BMI and fat percentage had a positive relationship with LS and FN BMD (LS BMD: r=.47, r=.56, r=.46, r=.34, r=.28, p≤.001, respectively; FN BMD: r=.34, r=.49, r=.51, r=.45, r=.27, p≤.001, respectively). In addition, there was no significant relationship between WHR and BMD of LS and FN (p˃.05). Multiple linear regression analysis showed the upper body strength was a stronger determinant of LS BMD and the lower body strength was a stronger determinant of FN BMD. Based on the results, the researchers concluded that upper and lower body strength, 2D:4D ratios and BMI were important determinants of young women’s BMD. Also, it seemed that some of these factors may be able to help predicting the osteoporosis potential in young women

Background and Study Aim: The aim of this research was to determine the differences between the young soccer players (U19) in terms of anthropometric characteristics and body composition. We considered players of three the most successful clubs in three countries of the southern region of the Balkan Peninsula. Material and Methods: The first sub-sample of the subjects was consisted of 17 players of OFC Titograd from Montenegro of the average age 17.12±.69. The second sub-sample was consisted of 14 players of FC Siroki Brijeg from Bosnia and Herzegovina of the average age of 18.14±.86. The last sub-sample of the examinees was consisted of 15 players of FC Feronikeli from Kosovo of the average age 18.07±.46. Anthropometric characteristics in the body composition were evaluated by a battery of 11 variables. The significance of the differences between the young soccer players in the anthropometric characteristics and variables for assessing body composition were determined by ANOVA and LSD Post Hoc test. Results: The young soccer players of the three mentioned clubs have statistically significant differences by the two variables that estimate the upper leg skinfold and fat percentage. The young soccer players of OFC Titograd are significantly better in variable upper leg skinfold than other players. The young soccer players of FC Feronikeli are significantly better in variable fat percentage than players of OFC Titograd. Conclusions: The results can be useful for coaches of other clubs for making a comparison of their soccer players with the young soccer players in this research.

The Relationship

Se propuso determinar la relación que existe entre la composición corporal y el rendimiento físico de jugadores de fútbol soccer universitario. Participaron 26 jugadores de sexo masculino con edad promedio de 20.7 años (DT = 1.7), pertenecientes a los equipos representativos de fútbol soccer de dos universidades mexicanas. Se midieron características morfológicas, de composición corporal y físicas para las posiciones de defensa, mediocampo y delantero. Se determinó el nivel de asociación entre las variables. Los resultados muestran que los defensas presentan mayor masa corporal, diámetro de húmero y circunferencia de cadera que los delanteros (p < .05), no así respecto a los jugadores de mediocampo. No se presenta diferencia en la expresión de las capacidades físicas y del porcentaje de masa grasa de los jugadores por posición de juego (p > .05). La masa grasa se asoció de manera directa con la velocidad (.427*, p < .05). Se encontraron diferencias en la masa ósea y corporal por posición de juego entre defensas, mediocampistas y delanteros. Los hallazgos sugieren la influencia de la composición corporal en el rendimiento físico de los participantes.  Abstract. The aim of the study was to determine the relationship between body composition and physical performance in college soccer players. Twenty-six male players with an average age of 20.7 years (SD = 1.7), belonging to the representative soccer teams of two Mexican universities participated in the research. Morphological, body composition, and physical characteristics were measured for the defense, midfield, and forward positions. The level of association between variables was determined. The results show that defenders have greater body mass, humerus diameter, and hip circumference than forwards (p <. 05), whereas no differences were found in comparison to midfielders. There is no difference in players’ expression of physical abilities and percentage of fat mass by playing position (p > .05). Fat mass was directly associated with speed (.427 *, p < .05). Differences were found in bone and body mass by playing position between defenders, midfielders, and forwards. The findings hint at an influence of body composition on participants’ physical performance.

The Relationship

Tumor resection is the first-line therapy for acromegaly patients. In some cases, unsatisfactory intraoperative neuromuscular blockades (NMBs) lead to failed operations. The purpose of this study was to investigate and quantify the NMB status of acromegaly patients and explore the relationship between NMB status and hormone levels and body composition. Twenty patients with untreated acromegaly and seventeen patients with nonfunctioning pituitary adenomas as controls were enrolled in this study. NMB was assessed using the train-of-four (TOF) technique with TOF-Watch® SX. The onset time of NMB, deep neuromuscular blockade duration (DNMBD), and clinical neuromuscular blockade duration (CNMBD) were monitored. We found a significantly longer onset time (110.25 ± 54.90 vs. 75.00 ± 27.56, s, p = 0.017 ), shorter DNMBD (21.99 ± 5.67 vs. 34.96 ± 11.04, min, p < 0.001 ), and shorter CNMBD (33.26 ± 8.09 vs. 46.21 ± 10.89, min, p < 0.001 ) in acromegaly patients compared with the controls. DNMBD and CNMBD decreased in patients with decreasing body fat percentage and increasing growth hormone (GH) level, insulin-like growth factor 1 (IGF-1) level, and GH and IGF-1 burden. The onset time increased with increasing IGF-1 level and GH and IGF-1 burden. Taken together, a unique NMB status was identified in acromegaly patients with the following characteristics: prolonged onset time and shortened DNMBD and CNMBD. Changes in the levels and burdens of GH and IGF-1 and body composition were linearly correlated with intraoperative NMB in acromegaly patients.

Especially for bicycle motocross (BMX) cyclists, transfer of muscular force-velocity (Fv) characteristics between common strength training exercises and cycling is important. This study investigated the relationship between Fv characteristics in a common training exercise (squat jumps) and a sport-specific task (cycling) in high-level BMX racers by exploring the degree to which Fv and torque–cadence (Tc) characteristics correspond. Twelve BMX racers performed an Fv (multiple loaded squat jump) and two Tc tests (ramp starts and flat-ground sprints). Results revealed very large correlations between F 0 and T o r 0 s t a r t (r = 0.77) and between P m a x j u m p and P m a x s t a r t (r = 0.85). On the other hand, the relationships between v 0 and C a d 0 s t a r t (r = –0.25) and between S F v and S T c s t a r t (r = –0.14) were small and negative. Similar results were observed for sprints. Based on dichotomous classifications (greater or less than group median), several discrepancies occurred, particularly for the profile slopes and high-speed variables. Thus, we recommend performing both jump-based and cycling-specific F v testing. Of additional note, T c characteristics on flat ground were similar to, but slightly different from those on the start ramp. Therefore, where possible, Tc tests should be carried out on a ramp.

This study aimed to investigate the effects of a five-week compound training (with strength and plyometric exercises performed on separate days) on sprint, change of direction, and vertical jump in young soccer players. Eighteen novices in strength and plyometric training were assigned to either a compound training (CMPT) or a control condition (CNT). Both groups trained three times per week. One session was dedicated to soccer-specific drills. The other two weekly sessions were dedicated to circuit-based training routines employing on one-day strength exercises and on the other day plyometric exercises in the CMPT group. At the same time, the CNT group performed two weekly soccer-specific training sessions. All players were tested by 15-m sprint, change-of-direction and acceleration test (CODAT), squat jump, and countermovement jump with arms swing tests. CMPT group improved CODAT, squat jump and countermovement jump to a higher extent compared to CNT group (large vs small or trivial effects, p < 0.05), while both groups had similar 15-m sprint performance (p > 0.05). These results support the use of compound training to improve change of direction and vertical jump performances in young novice soccer players, which are unfamiliar with structured and advanced strength and plyometric training.

The Relationship

Using the concept of mediatization, in this article, we analyze the relationship between sport and media from a sport-centered perspective. Examining the autobiographies of 14 German and English soccer players, we investigate how athletes use media outlets, what they perceive as the media’s influence and its logic, and—crucially—how this usage and these perceptions affect their own media-related behavior. Our findings demonstrate the important role of the media for the sports systems from the athlete’s point of view and demonstrate the research potential of mediatization as a fruitful concept in studies on sport communication. On the one hand, the sport stars reflect in their autobiographies that their status and income depend on media coverage; and on the other hand, they complain about the omnipresence of the media, especially offside the pitch and feel unfairly treated by the tabloid press, both in England and in Germany.

The Relationship

Context:Body-composition assessments of high-performance athletes are very important for identifying physical performance potential. Although the relationship between the kinanthropometric characteristics and performance abilities of Olympic swimmers is extremely important, this subject is not completely understood for Paralympic swimmers.Objective:To investigate the relationship between body composition and sport performance in Brazilian Paralympic swimmers 6 mo after training.Design:Experimental pre/posttest design.Setting:Research laboratory and field evaluations of swimming were conducted to verify the 50-m freestyle time of each athlete.Participants:17 Brazilian Paralympic swim team athletes (12 men, 5 women).Main Outcome Measures:Body-composition assessments were performed using a BOD POD, and swimming performance was assessed using the 50-m freestyle, which was performed twice: before and after 6 mo of training.Results:Increased lean mass and significantly reduced relative fat mass and swimming time (P < .05) were observed 6 mo after training. Furthermore, a positive correlation between body-fat percentage and performance (r = .66, P < .05) was observed, but there was no significant correlation between body density and performance (r = –.14, P > .05).Conclusions:After a 6-mo training period, Paralympic swimmers presented reduced fat mass and increased lean body mass associated with performance, as measured by 50-m freestyle time. These data suggest that reduced fat-mass percentage was significantly correlated with improved swimming performance in Paralympic athletes.
