Beaudoin, CM, Cox, Z, Dundore, T, Thomas, T, Kim, J, and Pillivant, D. Effect of bench press load knowledge on repetitions, rating of perceived exertion, and attentional focus. J Strength Cond Res 32(2): 514-519, 2018-Few studies have examined the role of the teleoanticipation during resistance training. The purpose of this study was to examine the effect of bench press (BP) load knowledge on repetitions completed, ratings of perceived exertion (RPEs), and attentional focus (% associative). Thirty-six recreationally active resistance-trained men (n = 25) and women (n = 11) participated in this study (age = 20.97 ± 1.87 years; ht = 174.12 ± 9.41 cm; and mass = 80.14 ± 14.03 kg). All subjects completed 3 testing sessions: (a) 1 repetition maximum (1RM) BP determination; (b) submaximal BP repetitions to fatigue known load (KL); and (c) submaximal BP repetitions to fatigue unknown load (UL). Known load and UL sessions were randomized and counterbalanced and both completed at 70% 1RM. An estimated weight ratio was computed using the subject's estimate of the UL weight relative to the KL weight. An independent samples t-test revealed no significant testing order difference for the estimated weight ratio. Two-way repeated-measures analysis of variances revealed no significant differences in the number of repetitions (p = 0.63), RPE (p = 0.18), or attentional focus (% associative) (p = 0.93) between the KL and UL conditions. Pearson correlations found a moderate positive association between KL repetitions completed and % associative focus when the UL was completed before the KL. Load knowledge did not influence the number of repetitions, RPE, or attentional focus while completing the BP. Further research examining the use of pacing strategies, RPE, and attentional focus during KL and UL conditions are warranted.

Mood and Performance Anxiety in High School Basketball Players: A Pilot Study.

Participation in competitive sport may impact psychological measures, such as mood and performance anxiety, which in turn may impact enjoyment, adherence, continued participation, and so on. This study assessed the feasibility - in terms of process, resources, management, and potential scientific value- of measuring the effect of varying competitive challenges upon the mood and performance anxiety measures of high school athletes. The participants (n=12) consisted of the boys' varsity basketball team at a high school in a rural Midwestern community. Participants completed the Profile of Mood States (POMS) to assess mood and the Sport Anxiety Scale-2 (SAS-2) to assess performance anxiety, respectively. Survey administration occurred at baseline and prior to games designated as non-conference, conference, and state tournament. A-priori feasibility measures were achieved in this prospective design. Significant correlations on the subscale measures were found on the POMS and SAS-2 administered before the four conditions in this study; Chronbach's alpha ranged from 0.54-0.94 across conditions for POMS subscales, and Chronbach's alpha ranged from 0.73-0.97 across all conditions for SAS-2 subscales, respectively. Significant differences were found across conditions in the POMS subscale confusion [F(3,33) = 5.71, p = 0.01] and in the SAS-2 subscale worry [F(3,33) = 6.13, p=0.01]. These preliminary findings suggest that the competitive conditions in this study significantly affected some measures of mood and performance anxiety in high school basketball players. These findings warrant further investigation, as well as suggest coaches could gather such information from their players, ultimately aiding in player development and team performance.

Can Dance Exergames Boost Physical Activity as a School-Based Intervention?

BACKGROUND: Children need opportunities to have physical activity (PA). Using exergames could be a feasible and acceptable way to boost PA in middle schools. Our goal was to increase PA by 40 minutes per week and to determine how much time, if any, was spent in moderate-to-vigorous PA (MVPA). SUBJECTS AND METHODS: Eighty-four middle school youth were in a pilot study for 20 weeks: half in the Generation Fit (GenFit) intervention group and half in the control group. The GenFit group played the exergame for the first 10 weeks (Session 1), and the control group joined from 10 to 20 weeks (Session 2). The main outcome was exergaming time per student per week. RESULTS: Fifty-eight students completed the pilot after 26 youth at School C were excluded for administrative reasons. Of those remaining, 40 students at School A and 18 students at School B, the average age of the sample was 13.7 years (SD=0.6), and average body mass index percentile was close to 70. During Session 1, the average dance time per child was 49 minutes per week, versus 54 minutes per week in Session 2. Mean body mass index percentile decreased by 5.6 for children who participated in GenFit, compared with 0.2 for children in the control group. At end point, accelerometers showed over half of the dance time was spent in MVPA. Qualitative data showed that most children found the exergame acceptable. CONCLUSIONS: A dance exergame in middle schools offered opportunities for PA. About half of the exergame time was spent in MVPA. Exergames may be feasible and acceptable in middle schools to boost PA, and access could provide a way for schools to support the health of students.

Location of food stores near schools does not predict the weight status of Maine high school students.

OBJECTIVE: To examine the relationship between stores selling calorie-dense food near schools and student obesity risk, with the hypothesis that high availability predicts increased risk. METHODS: Mail surveys determined height, weight, and calorie-dense food consumption for 552 students at 11 Maine high schools. Driving distance from all food stores within 2 km (1.24 miles) of schools (or the closest store) was computed, and the impact of food store density and proximity to schools on student body mass index was determined by logistic regression. RESULTS: Ten schools had ≥ 1 store selling soda, and 8 schools had ≥1 fast-food restaurant within 1 km (0.62 miles). There were no significant relationships between the proximity or density of food stores around schools and student obesity risk. Students obtained sugar-sweetened beverages in many locations including at school. CONCLUSIONS AND IMPLICATIONS: Unhealthful food choices are ubiquitous. Consequently, stores selling these food items near schools have no significant affect on student obesity.

Impact of Maine's statewide nutrition policy on high school food environments.

INTRODUCTION: We assessed the effect on the food environments of public high schools of Maine's statewide nutrition policy (Chapter 51), which banned "foods of minimal nutritional value" (FMNV) in public high schools that participated in federally funded meal programs. We documented allowable exceptions to the policy and describe the school food environments. METHODS: We mailed surveys to 89 high school food-service directors to assess availability pre-Chapter 51 and post-Chapter 51 of soda, other sugar-sweetened beverages, and junk food. Frequency data were tabulated pre-Chapter 51 and post-Chapter 51, and Fisher exact test was used to assess significance in changes. We conducted food and beverage inventories at 11 high schools. RESULTS: The survey return rate was 61% (N = 54). Availability of soda in student vending significantly decreased pre-Chapter 51 versus post-Chapter 51 (P = .04). No significant changes were found for other sugar-sweetened beverages and junk food. Exceptions to Chapter 51 were permitted to staff (67%), to the public (86%), and in career and technical education programs (31%). Inventories in a subset of schools found no availability of soda for students, whereas other sugar-sweetened beverages and junk food were widely available in à la carte, vending machines, and school stores. Candy, considered a FMNV, was freely available. Soda advertisement on school grounds was common. CONCLUSION: Student vending choices improved after the implementation of Chapter 51; however, use of FMNV as the policy standard may be limiting, as availability of other sugar-sweetened beverages and junk food was pervasive. School environments were not necessarily supportive of the policy, as advertisement of soda was common and some FMNV were available. Furthermore, local exceptions to Chapter 51 likely reduced the overall effect of the policy.

Reduced availability of sugar-sweetened beverages and diet soda has a limited impact on beverage consumption patterns in Maine high school youth.

OBJECTIVE: To examine change in high school students' beverage consumption patterns pre- and post-intervention of reduced availability of sugar-sweetened beverages (SSB) and diet soda in school food venues. DESIGN: A prospective, quasi-experimental, nonrandomized study design. SETTING: Public high schools. PARTICIPANTS: A convenience sample from control (n = 221) and intervention (n = 235) high schools. INTERVENTION: Schools aimed to reduce (n = 4) or not change (n = 3) availability of SSB and diet soda in food venues for 1 school year. MAIN OUTCOME MEASURES: Subjects' beverage servings/day was determined from a food frequency questionnaire pre- and post-intervention. ANALYSIS: Two-by-two mixed analysis of variance model compared pre- to post-intervention servings/day between control and intervention subjects, stratified by gender. RESULTS: Consumption of SSB decreased in both intervention and control boys (F = 53.69, P < .05) and girls (F = 22.87, P < .05). Intervention girls decreased diet soda consumption as compared to control girls (F = 6.57, P < .05). CONCLUSION AND IMPLICATIONS: Reducing availability of SSB in schools did not result in a greater decrease in SSB consumption by intervention as compared to control subjects. The impact of reducing availability of SSB at school may be limited. A better understanding of beverage consumption patterns may be needed to determine the efficacy of school food policies on those youth susceptible to obesity.

Implementation of low-fat, low-sugar, and portion-controlled nutrition guidelines in competitive food venues of Maine public high schools.

BACKGROUND: The prevalence of childhood "overweight" and "at risk for overweight" has become a major public health concern. School food environments can affect key nutritional risk factors, especially in high schools where foods of poor nutrient value are pervasive in à la carte and vending programs. This study examines à la carte and vending programs in Maine public high schools at baseline and following implementation of low-fat (defined as items

The vending and à la carte policy intervention in Maine public high schools.

BACKGROUND: A healthy school nutrition environment may be important for decreasing childhood overweight. This article describes a project to make healthier snacks and beverages available in vending machines and à la carte programs in Maine public high schools. CONTEXT: Seven public high schools in Maine volunteered to participate in this project. Four schools made changes to the nutrition environment, and three schools that served as controls did not. The nutrition guidelines were to offer only low-fat (not more than 30% of total calories from fat) and low-sugar (not more than 35% by weight of sugar) items in vending machines and à la carte programs. METHODS: Strategies to implement the project included early communications with school officials, monetary stipends for participation, identification of a school liaison, and a committee at each school to promote the healthy changes. Baseline nutrient content and sales of all competitive foods and beverages were assessed to develop the guidelines for changes in the four schools. Student volunteers at all seven schools were measured for height, weight, diet quality, and physical activity level to assess the impact of the change to the nutrition environment. Baseline measures were taken in the spring semester of 2004. Nutrition changes were made to the à la carte programs and vending machines in the four intervention schools at the start of the fall semester of 2004. Follow-up nutrition assessment and student data collection occurred in the spring semester of 2005. CONSEQUENCES: Healthy changes in vending machines were more easily achieved than those made in the à la carte programs. Technical assistance and ongoing support were essential for successful implementation of this intervention. INTERPRETATION: It is possible to improve the nutrition environment of Maine public high schools. Stakeholder support is essential to sustain healthy changes.

Physical activity patterns and maternal well-being in postpartum women.

OBJECTIVE: To examine changes in activity prepregnancy to postpartum; examine postpartum activity and sociodemographic predictors of maternal well-being; and, examine maternal well-being in subjects on the basis of sport/exercise activity prepregnancy to postpartum. METHODS: Ninety-one postpartum women completed a Kaiser Physical Activity Survey (KPAS) Ainsworth BE, Sternfeld B, Richardson MT, Jackson K. Evaluation of the Kaiser Physical Activity Survey in women. Med Sci Sports Exerc 2000; 32:1327-38. and the Lederman Postpartum Questionnaire (PPQ) Lederman RP, Weingarten CT, Lederman E. Postpartum self-evaluation questionaire: Measures of maternal adaptation. In: Raff BS, Carrol P, editors. Perinatal parental behaviour: Nursing research and implications for newborn health. New York: Alan R. Liss, 1981:201-31. Subjects recalled activity prepregnancy and postpartum for the KPAS indexes that included household/care giving (HC), active living habits (AL), occupation (0), and sports/exercise (SE). The PPQ has seven well-being subscales. RESULTS: Subjects with older infants or no other children increased HC and decreased O prepregnancy to postpartum compared to subjects with younger infants or > or =1 other child. Predictors of the variance in the PPQ subscales included SE and AL (21% in subscale one), SE (6.0% in subscale two), HC (5.3% in subscale three), socioeconomic status (19.7% in subscale four), O (5.0% in subscale five), education (5.2% in subscale seven). Subjects who maintained or increased SE showed better well-being as compared to subjects who reported no SE or decreased SE prepregnancy to postpartum. CONCLUSIONS: In this group of women, subjects with older infants or no other children reported higher HC and lower O prepregnancy to postpartum. Postpartum SE, education, and socioeconomic status were predictors of maternal well-being. In general, better maternal well-being was found among subjects maintaining or increasing SE compared to no SE or decreased SE prepregnancy to postpartum. Support from partner/husband, family, and friends were significant factors in maintaining or increasing SE.
