Introduction: Sports performance has currently developed in a fast and concrete way, requiring hence an efficient evolution of different areas of sports sciences, offering scientific support necessary to the continuity of this phenomenon. Objetive: The present study aimed to develop a prediction mathematical equation for bone age of young athletes, based on anthropometric variables. Methods: In order to achieve the final result, skinfolds, body circumferences and bone diameters, chronological age and bone age have been measured. The statistical treatment used correlation between variables, a multiple linear regression model with backward. Results: The study presented as final result a model equation which explains 75.4% (r = 0.868; R2 = 0.754) of the variation of the bone age using chronological age, height, triceps skinfold, arm corrected perimeter and femur and humerus diameters. Conclusion: It was concluded from the results that this type of model shows approximate values to those observed through hand and wrist radiography, which makes it important in the observation of maturational stage through tests of easy application performed by professionals of the sports field.

Resistance training (RT) can provide several benefits for individuals with Type 2 diabetes. The aim of this study was to investigate the effects of resistance training on the strength levels and uric acid (UA) concentration in individuals with Type 2 diabetes. The study included 68 patients (57.7±9.0 years) that participated in an organized program of RT for 12 weeks. The volunteers were divided into two groups: an experimental group (EG; n=34) that performed the resistance training program consisting of seven exercises executed in an alternating order based on segments; and a control group (CG; n=34) that maintained their normal daily life activities. Muscle strength and uric acid were measured both pre- and post-experiment. The results showed a significant increase in strength of the subjects in the EG for all exercises included in the study (p<0.001). Comparing the strength levels of the post-test, intergroup differences were found in supine sitting (p<0.001), leg extension (p<0.001), shoulder press (p<0.001), leg curl (p=0.001), seated row (p<0.001), leg press (p=0.001) and high pulley (p<0.001). The measured uric acid was significantly increased in both experimental and control groups (p<0.001 and p=0.001, respectively). The intergroup comparison showed a significant increase for the EG (p=0.024). We conclude that the training program was effective for strength gains despite an increase in uric acid in Type 2 diabetics. © 2014 by Moisés S.S. R. Sousa. Source
