Over 1,500 events and activities are held annually in all 50 states to celebrate and promote female participation in sport. This article introduces the sport/activity-clinic model of the NGWSD event hosted annually at Idaho State University (ISU) and provides planning strategies—such as volunteer recruitment and organization, facility planning, marketing and promotion, and risk management—that can be use to plan your own NGWSD event.

Swimming. This study was quantitative and focused on the development and field-testing of standardized training intensity guidelines, based on the blood lactate curve and energy metabolism. The findings showed that as intensity increased so did participants’ blood lactate concentration, heart rate, and ratings of perceived exertion. A Pearson product-moment correlation analysis between the mean values of blood lactate concentration, heart rate, and ratings of perceived exertion, and the corresponding training intensity ranges revealed significant positive correlations between mean blood lactate values (r = 0.99, p < 0.001), mean heart rate (r = 0.96, p < 0.001); and ratings of perceived exertion (r = 0.99, p < 0.005). Correlation analyses between heart rate and measures of blood lactate were positive (r = 0.70, p >0.05), as were heart rate and ratings of perceived exertion (r = 0.96, p < 0.005). Measures of blood lactate were positively and significantly correlated to ratings of perceived exertion (r = 0.82, p <0.05). These findings validated the training intensity guidelines model.

Quiet-eye training, perceived control and performing under pressure

While previous studies have explored how quiet-eye (QE) training optimizes objective (visual attention) control in aiming tasks, this study examined whether QE training influences perceived (psychological) control and how changes in control beliefs correspond to changes in anxiety, visual attention and performance under pressure.
Two groups of ten experienced soccer penalty takers followed either a QE training program or a practice program where penalty kicks were practiced with no instruction. Measurements of anxiety, gaze, performance and perceived control were recorded over baseline, retention and a competitive, ’shoot-out’ transfer condition.
Not only did the QE training optimize aiming behavior and performance, but these changes in visual attention were mirrored in changes in control beliefs. QE participants significantly reduced their perceptions of outcome uncertainty (contingency) and increased their perceptions of shooting ability (competence) and ability to score and cope with the pressure (control), compared to practice participants. Furthermore, there was an overall and significant relationship between high perceptions of control beliefs and aiming behavior. Specifically, those participants with high control beliefs were more likely to aim optimally and further from the goalkeeper, whereas participants with low control beliefs experienced suboptimal and more centralized aiming behavior.
These findings are the first to highlight the relationship between control beliefs, anxiety and attentional control in sport and offer further explanations regarding the benefits of QE training for performance under pressure.

Nineteen participants with low-level soccer experience practised a left-footed, soccer-chip shot, which required them to land a ball on a target, while clearing a height barrier. Information concerning how to achieve the task goal was manipulated. Participants either received demonstrations of an expert performing the skill (i.e., BODY, n = 10) or they received a demonstration of the expert's ball flight path (BALL, n = 9). The participants were asked to match the criterion flight or form to achieve the task goal. Feedback concerning ball flight and movement form was controlled, although all participants received KR. Trials were videotaped for analyses and feedback and movement kinematics were collected using 3D cameras on a selection of trials. Both groups improved during acquisition although there was no significant difference between the groups in terms of outcome attainment (i.e., height success and radial error). In retention, the BALL group showed more accurate performance relative to the BODY group, when demonstrations and feedback were withheld. Only in acquisition were any differences between the two groups noted in terms of movement kinematics. The BODY group showed a closer approximation to the model in terms of how various joint displacement angles were obtained (but not the actual angles) in comparison to the BALL group. These results provide initial evidence to support the use of end-point template matching strategies for teaching complex movement skills, such as those common in sports which require the accurate displacement of some external object (such as a ball or disc).
High-intensity training improves airway health in inactive non-asthmatic children.

The purpose of this study was to determine whether 8 wk of high-intensity exercise training would improve airway responsiveness in prepubescent, nonasthmatic, inactive children. Methods: 16 healthy, prepubescent children were randomized [training group (TrG) n = 8, control group (ConG) n = 8]. Prior to and following 8 wk of training (or no training), children completed pulmonary function tests (PFTs): forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), forced expiratory flow at 25–75% of vital capacity (FEF25–75), and exhaled nitric oxide (FENO). Children completed an incremental cycle V̇O2max test, eucapnic voluntary hyperventilation (EVH), anthropometric tests, and blood tests to determine fasting blood glucose, total cholesterol, HDL, LDL, and triglycerides. Body fat percentage was determined using dual-energy X-ray absorptiometry pretraining and bioelectrical impedance pre- and posttraining. Results: there were no differences (P > 0.05) in anthropometric measures or PFTs between TrG and ConG at baseline. In the TrG, there was a significant increase in V̇O2max (∼24%) and a decrease in total cholesterol (∼13%) and LDL cholesterol (∼35%) following training. There were improvements (P < 0.05) in ΔFEV1 both postexercise (pre: −7.60 ± 2.10%, post: −1.10 ± 1.80%) and post-EVH (pre: −6.71 ± 2.21%, post: −1.41 ± 1.58%) with training. The ΔFEF25–75 pre-post exercise also improved with training (pre: −16.10 ± 2.10%, post: −6.80 ± 1.80%; P < 0.05). Lower baseline body fat percentages were associated with greater improvements in pre-post exercise ΔFEV1 following training (r = −0.80, P < 0.05). Conclusion: these results suggest that in nonasthmatic prepubescent children, inactivity negatively impacts airway responsiveness, which can be improved with high-intensity training. Excess adiposity, however, may constrain these improvements.
