Issue Date: | 2015 | Publisher: | 0212-1611 | Journal: | Nutrición Hospitalaria | Abstract: | The effects of basketball on basal concentrations of testosterone and cortisol and its associations to body composition and physical performance remain to be de-termined.Aim:the main aim of this study was to determine the effects of playing position on physical fitness, percentage of body fat and hormonal profile in professional basket-ball players (BP).Method:jump performance (SJ, CMJ and ABK), 30 m running speed and treadmill VO2max tests were con-ducted in 12 male BP (24.1 years) from the first division league of Spain (ACB). The percentage of body fat was determined from anthropometry, and hemoglobin, glu-cose, testosterone and cortisol concentrations were mea-sured from fasting blood samples. BP were divided into 3 groups depending on playing positions: guards (GU), forwards (FW) and centers (CE) (n = 4 in each group).Results:GU had greater percentage of body fat (%BF) than CE (p < 0.05). CE developed greater positive mecha-nical impulse than GU in all jump types (p < 0.05) and achieved higher maximal instantaneous power than GU and FW in the SJ and ABK (p < 0.05). Centers had more plasma testosterone than guards (p < 0.05). All groups a similar relative VO2max.Conclusion:center position was associated to lower adiposity and higher jumping performance than playing as guards. All playing positions induced a similar effect on aerobic power. | URI: | http://hdl.handle.net/10553/48341 | ISSN: | 0212-1611 | DOI: | 10.3305/nh.2015.31.6.8977 | Source: | Nutricion Hospitalaria[ISSN 0212-1611],v. 31, p. 2624-2632 |
