ABSTRACT Studies on running biomechanics and energetics are usually conducted on a treadmill. To ensure that locomotion on a treadmill is comparable to locomotion overground, participants need to be expert in the use of the device. This study aimed to identify the number and duration of sessions needed to obtain stable measurements for spatiotemporal and metabolic parameters in unexperienced treadmill runners. Fourteen male recreational runners performed three 15-min treadmill running trials in different days at a submaximal speed. Spatiotemporal and metabolic parameters were registered at minutes: 5, 10, 15 and their within-trial and between-trial changes were analysed using a two-way repeated measures ANOVA and Bonferroni post-hoc test. Within-trial differences were found in step frequency (decreased over time), Step Length and Contact Time (increased), reaching stability at different time points. Ventilator parameters increased, reaching stability after 5–10 min, while heart rate increased progressively over time. The only between-trial differences were an increase in step length and a decrease in step frequency at min 1, between trials 1 and 3. In conclusion, at least three running trials of 15 min are required to familiarize with the device. The last 5 min of the third trial can be regarded as stable measurements. 相似文献

Expectant and new parents have many concerns regarding the relationship between sexuality and breastfeeding. How is a new mother''s libido affected by breastfeeding? Why do some women get sexually excited when breastfeeding? Is this frequent or normal? How does the partner feel about breasts full of milk? Why do breasts leak during a woman''s orgasm? Perinatal educators are in a privileged position to reassure these parents about this relationship while promoting the breastfeeding bond between the mother and child and the intimacy bond between the parents. 相似文献

Positive school environments and school belonging have been associated with a variety of positive academic, social, and psychological outcomes among youth. Yet, it is not clear how these constructs are related, and few studies have focused on urban at‐risk youth with disabilities. This study examines baseline survey data from 136 low‐income African American and Latino students in grades 5 to 12, most of whom have disabilities, recently transferred following a school closure. Using structural equation modeling, we tested a model that examined the relationships among school stressors and resources, school belonging, academic outcomes (school satisfaction and academic self‐efficacy), and psychological outcomes (anxiety and depression). This model was an excellent fit with the data, and findings indicate that school belonging plays a central role in explaining how school context can affect both psychological and academic outcomes. This model has implications for school‐based interventions that can enhance student success and well‐being. © 2008 Wiley Periodicals, Inc. 相似文献

Current undergraduate medical curricula provides relatively little time for cadaver dissection. The Department of Human Anatomy and Physiology at the University of Padova has organized a pilot project with the University Hospital for the donation of body parts that are surgically removed for therapeutic purposes and destined under Italian law for destruction. The aim of the project is to improve residents' practical training skills. A survey over the last two years has shown that about 60 body parts were available each year. These included 13 upper limbs or their parts (i.e., forearm with hand, hand, and fingers) and 47 lower limbs or their parts (i.e., legs with feet, feet, or toes). The residents explained the aim of the project to potential donors, and, if patients were willing to donate, their informed consent was obtained. The residents were present in the operating theater during the surgical procedure. In the post-operative phase, the same residents performed dissections on the body part(s), following a teaching schedule prepared by a clinical anatomist, who also assisted residents during their studies. Residents also acted as tutors for undergraduate medical students who attended these dissections. The underlying pathology for which the body part was removed was examined, and surgical procedures were practiced on the body part itself. Our project provided an opportunity for a close relationship between anatomists and surgeons, reinforcing core knowledge of anatomy by appreciation of its clinical importance. The active involvement of residents as learners and as teachers in the various steps of this project improved their knowledge of surgical techniques and helped to establish a sense of ethical responsibility and respect for the human body. This approach involves study of anatomical structures from new perspectives and leads to improved surgical practice. 相似文献

Translation is a process that involves transformation and reproduction. This essay discusses some useful techniques of translating practice by introducing a simple model. A few examples of good translation are presented to support explaining the model clearly. 相似文献

The anatomical theatre played a pivotal role in the evolution of medical education, allowing students to directly observe and participate in the process of dissection. Due to the increase of training programs in clinical anatomy, the Institute of Human Anatomy at the University of Padova has renovated its dissecting room. The main guidelines in planning a new anatomical theatre included: (1), the placement of the teacher and students on the same level in a horizontal anatomical theatre where it is possible to see (theatre) and to perform (dissecting room); (2), in the past, dissection activities were concentrated at the center of the theatre, while in the new anatomical theatre, such activities have been moved to the periphery through projection on surrounding screens—thus, students occupy the center of the theatre between the demonstration table, where the dissection can be seen in real time, and the wall screens, where particular aspects are magnified; (3), three groups of tables are placed with one in front with two lateral flanking tables in regards to the demonstration table, in a semicircular arrangement, and not attached to the floor, which makes the room multifunctional for surgical education, medical students and physician's continued professional development courses; (4), a learning station to introduce the students to the subject of the laboratory; (5), cooperation between anatomists and architects in order to combine the practical needs of a dissection laboratory with new technologies; (6), involvement of the students, representing the clients' needs; and (7), creation of a dissecting room of wide measurements with large windows, since a well‐illuminated space could reduce the potentially negative psychological impact of the dissection laboratory on student morale.

The present paper describes the activity carried out to investigate the aerodynamic effects of cycling shoes for time trial
competitions. This subject has not been widely studied but can be important for an accurate aerodynamic optimisation of a
time trial cyclist. The study was carried out by means of wind tunnel testing: an appropriate test setup and an appropriate
test procedure (based on “effective angle of attack approach”) were developed in order to produce realistic test conditions.
The developed testing procedure was applied to two different shoe models, differently fastened. Furthermore, an important
point was the investigation of the overshoe effect. The results showed that the power required to overcome the shoe’s drag
is almost a tenth of the total power and that differences between the shoes can affect the cyclist’s performance. 相似文献
