- Plyometric exercise combined with high-intensity interval training improves metabolic abnormalities in young obese females more so than interval training alone(2016) RACIL, Ghazi; ZOUHAL, Hassane; ELMONTASSAR, Wassim; ABDERRAHMANE, Abderraouf Ben; SOUSA, Maysa Vieira De; CHAMARI, Karim; AMRI, Mohamed; COQUART, Jeremy B.The aim of this study was to compare the effects of 12 weeks of high-intensity interval training (HIIT) with the effects of 12 weeks of plyometric exercise combined with HIIT (P+HIIT) on anthropometric, biochemical, and physical fitness data in young obese females. Sixty-eight participants (age, 16.6 +/- 1.3 y; body mass, 82.8 +/- 5.0 kg; body fat, 39.4% +/- 3.3%; body mass index z score, 2.9 +/- 0.4) were assigned to 1 of 3 groups: HIIT (2 blocks per session of 6-8 bouts of 30-s runs at 100% velocity at peak oxygen uptake, with 30-s active recovery between bouts at 50% velocity at peak oxygen uptake (n = 23)); P+HIIT (2 blocks per session of 3 different 15-s plyometric exercises with 15-s passive recoveries, totaling 2 min for each plyometric exercise + the same HIIT program (n = 26)); or control (no exercise (n = 19)). Anthropometric (body mass, body mass index z score, body fat, lean body mass, and waist circumference), biochemical (plasma glucose, insulin, leptin and adiponectin concentrations, leptin/adiponectin ratio, and homeostasis model assessment of insulin resistance (HOMA-IR)), physical fitness (peak oxygen uptake, velocity at peak oxygen uptake, squat jump, and countermovement jump performances), and energy intake data were collected. Both training programs improved the anthropometric, biochemical, and physical fitness variables. However, the P+HIIT program induced greater improvements than did the HIIT program in lean body mass (+3.0% +/- 1.7%), plasma glucose and leptin concentrations (-11.0% +/- 4.7% and -23.8% +/- 5.8%, respectively), plasma leptin/adiponectin ratio (-40.9% +/- 10.9%), HOMA-IR (-37.3% +/- 6.2%), and squat jump performance (22.2% +/- 7.5%). Taken together, these findings suggest that adding plyometric exercises to a HIIT program may be more beneficial than HIIT alone in obese female adolescents.
article 7 Citação(ões) na Scopus Body dissatisfaction and the wish for different silhouette is associated with higher adiposity and fat intake in female ballet dancers than male(2016) SILVA, Camila Lacerda Da; OLIVEIRA, Erick Prado De; SOUSA, Maysa Vieira De; PIMENTEL, Gustavo D.BACKGROUND: It is known that behavioral disorders and altered food intake are linked to ballet dancers. Thus, the aim of the present study was to investigate the body composition, dietetic profile, self-perceived body image and social desirability in professional ballet dancers. METHODS: This study was conducted from April to October 2010 in athletes screened for nutritional evaluation. Anthropometric, dietary, social desirability and self-perceived body image evaluation were performed to attend the aim of study. RESULTS: We found that ballet dancers are highly trained and eutrophic, although female dancers had higher adiposity and fat intake than male dancers. In addition, it was observed low consumption of calcium, dietary fiber, potassium, magnesium and vitamin A. Moreover, 30% of male ballet dancers have a strong desire for social acceptance. When the body image was evaluated by Body Shape Questionnaire (BSQ), was reported that 40% of the ballet female dancers have of moderate to severe alteration in body image and 20% of male dancers had slight alteration. Furthermore, the Drawings and Silhouettes Scale showed that 80% of male dancers wish to have a smaller or larger silhouette than the current self-perceived and 60% of the female dancers would like to have a silhouette lower than the self-perceive as current. CONCLUSIONS: Collectively, our results shown that most of the dancers were eutrophic, but female athletes have higher adiposity and present strong desire for a different shape of current. Furthermore, was found increased fat intake in female group; however, deficiencies in consumption of dietary fiber, calcium, potassium, magnesium and vitamin A were found in both gender.
