High performance sport has a major impact on the physiological adaptations of the respiratory system. The importance of the optimal functioning of this system is essential to achieve top results in high performance sport but also in maintaining a long term health status. Science journals present numerous studies that highlight the benefits of practicing Tai Chi on the general population, with effects ranging from improving cardiac function, to influencing the immune system. The purpose of this study is to identify whether by practicing Tai Chi forms a athlete can change their breathing pattern and develop their respiratory amplitude. The subjects of the study were 22 fencing practitioners, accredited at the Iași Municipal Sports Club (C.S.M. Iași), aged between 14 and 18 years, with over 3 years of competitive activity. Materials and method: The study participants were evaluated initially and at the end of 7 months of practice. The frequency was 3 sessions per week, and the duration of each session was 20-30 minutes. The evaluation consisted in measuring the circumference of the thorax at 3 different levels: subaxillary, medial thorax (T6-T7) and lower rib (diaphragmatic) in maximal inspiration and expiration. Conclusions: A constant evolution is observed in most of the exposed cases. In cases where this evolution is not visible, a change in the breathing mode can be noticed, transforming from an upper rib breathing into a thoracic or abdominal breathing. With the exception of one case, all subjects had an improvement of the value in the lower rib level.

AbstractExploring low-cost and earth-abundant oxygen reduction reaction (ORR) electrocatalyst is essential for fuel cells and metal–air batteries. Among them, non-metal nanocarbon with multiple advantages of low cost, abundance, high conductivity, good durability, and competitive activity has attracted intense interest in recent years. The enhanced ORR activities of the nanocarbons are normally thought to originate from heteroatom (e.g., N, B, P, or S) doping or various induced defects. However, in practice, carbon-based materials usually contain both dopants and defects. In this regard, in terms of the co-engineering of heteroatom doping and defect inducing, we present an overview of recent advances in developing non-metal carbon-based electrocatalysts for the ORR. The characteristics, ORR performance, and the related mechanism of these functionalized nanocarbons by heteroatom doping, defect inducing, and in particular their synergistic promotion effect are emphatically analyzed and discussed. Finally, the current issues and perspectives in developing carbon-based electrocatalysts from both of heteroatom doping and defect engineering are proposed. This review will be beneficial for the rational design and manufacturing of highly efficient carbon-based materials for electrocatalysis.

This study examined the choices made by adolescent girls in physical education classes when allowed to choose from among a variety of walking activities. Following the TARGET (Epstein, 1988; Treasure & Roberts, 1999) structures, nine walking activities were created to reflect one of four themes: social, exercise/fitness, game-like, or competition. Participants were 570 girls from 21 intact 7th and 8th grade classes from five schools in two school districts. Every 3 days for 9 days, students chose from a list of three activities representing a combination of the four themes. They were significantly more likely to choose (a) a social activity over two exercise and fitness activities; (b) either a game-like or competitive activity over an exercise/fitness activity; and (c) a social activity over a game-like activity or a game-like activity over a competitive activity. Adolescent girls may benefit from activities that are designed to be social, game-like, and/or competitive.

Objectives: 1) To compare ability to return to prior competitive sports activity after arthroscopic hip surgery by gender, with an emphasis on the rate of return to the same level of competition. 2) To compare gender differences in type of sports activities, diagnosis and treatment in athletes requiring hip arthroscopy. Methods: Prospectively obtained data on all high-level elite athletes (professional, NCAA collegiate and/or Olympic) treated between 2007 and 2014 were retrospectively reviewed. The clinical and surgical records of 547 hips in 484 consecutive patients who underwent primary hip arthroscopy by the senior author for non-arthritic hip pain during the study period were included. Elite athletes who had a Hip Sports Activity Score (HSAS) of over 6 were identified. Patients completed a pre-operative questionnaire that included medical and sports activity history and level of competition, hip-specific outcome scores (Modified Harris Hip Score [MHHS] and International Hip Outcome Tool-33 [iHOT-33]) at baseline and most recent follow-up. Surgical findings and time to return to competitive sports activity were documented. Results: A total of 98 elite athletes with a mean follow up period of 18.8 months (±12.7) were identified. There were 49 females and 49 males. 27 athletes had bilateral hip arthroscopy, 5 of which had 1 operation elsewhere. All patients were available for follow up. Of the 80 patients desiring to return to their original competitive activity, 38 were female (42 hips) (Female Athlete group [FA]) and 42 were male (54 hips) (Male Athlete group [MA]) their mean ages were 21.5(±3.9) and 20.5(±1.9), duration of pain prior to surgery was 12.1 (±10.3) months and 15.1 (±1.9) months, respectively. 84.2% of FA and 83.3% of MA were able to return to the same level of competition at a mean of 8.3 (±3) and 8.8 (±2.9) months, respectively. Statistically significant improvements between pre- and post-operative mean MHHS and iHOT-33 scores were seen in both groups (p <.0001; p <.0001). FA had significantly higher proportions of hips that were diagnosed with Pincer type FAI (p =.0004), and Instability (p <.0001). Conversely, the MA had significantly higher proportions of hips that were diagnosed with Combined type FAI (p <.0001), had more extensive acetabular cartilage rim damage (p =.0002), and in particularly had more hips that required microfracture treatment (p =.001). When comparing cam lesions (includes Cam and Combined type FAI) the alpha angle was statistically greater in MA (mean 74°±6.7) compared to FA (mean 65.4°±6.8) (p <.0001). The category of sports the FA participated in were more flexibility (11%) and endurance (24%) type sports. MA participated more in cutting (33%), contact (14%) and asymmetric (31%) type sports. Patients who were able to return to same level of competitive activity had a significantly shorter duration of pre-operation symptoms compared to those who could not (p < 0.05). Microfracture treatment did not affect the ability to return to sports. Conclusion: A similar high percentage of both female and male elite athletes were able to return to competitive sports activity after arthroscopic treatment of FAI and/or hip instability. Distinct differences in diagnosis, treatment and participating type of sports activities were seen when comparing female and male athletes. Duration of symptoms negatively correlated with outcomes. Extensive cartilage damage and Microfracture did not affect outcome / return to sports.
