Effects of After-School Volleyball Program on Body Composition in Overweight Adolescent Girls

The current study aimed to investigate the effects of an after-school volleyball program on body composition in overweight adolescent girls. Forty-two girls were randomly divided into a volleyball group (VG) (n = 22 age: 15.6 ± 0.5 years) and control group (CG) (n = 20; age: 15.5 ± 0.7years). Both groups continued with their usual physical education activities, while VG was included as small-sided games, two times a week, after school, on modified volleyball courts. Body mass, body mass index (BMI), body fat in kg, body fat percentage, and muscle mass were analyzed by a bioelectrical impedance method. There was a significant interaction of group (VG vs. CG) x time (pre-vs. post) for weight [F1, 40 = 7.933; p = 0.004] and BMI [F1, 40 = 5.764; p = 0.015]. Additionally, a significant main effect of time was found for body fat (kg) [F1, 40 = 17.650; p < 0.001] and body fat (%) [F1, 40 = 18.721; p < 0.001]. The results of the current study show that a twelve-week after-school volleyball program, including two sessions a week, can improve body composition in overweight adolescent girls.

The Beneficial Effects of Moxibustion on Overweight Adolescent Girls

Among adolescent girls, overweight or obesity has both physical and psychological involvement. We conducted a randomized controlled trial of moxibustion using a moxa burner. Fifty-four eligible girls aged 15–18 years with a body mass index (BMI) greater than 25.3 were enrolled in the study. The girls were randomly allocated to the treatment (n = 27) and control (n = 27) groups. The girls underwent treatment three times per week for 8 weeks (24 treatments). Moxibustion was applied to the RN12, RN6, ST25, ST36, and SP6 acupoints. Physical assessments were BMI, waist-to-hip ratio (WHR), and body fat ratio (BFR). Psychological outcomes were measured using the Rosenberg Self-Esteem Scale (RSE). Data were collected at the beginning of the study (baseline), week 4, and week 8. Of the 54 participants, 46 completed the trial. The difference in mean BMI from baseline between the two groups was 0.097 ( p = 0.655 ) at week 4 and −0.794 ( p = 0.001 ) at week 8. The mean WHR of the treatment group was significantly reduced compared with baseline, with a −0.011 ( p = 0.017 ) and −0.035 ( p < 0.001 ) mean change at weeks 4 and 8, respectively. The mean BFR was slightly reduced (−0.253; p = 0.474 ) at week 4 compared with baseline in the treatment group. At week 8, it was significantly reduced (−2.068; p < 0.001 ) from baseline in the treatment group. The mean RSE in the treatment group showed no significant increase from baseline at week 4 (0.155 points, p = 0.803 ), but it improved significantly from baseline at week 8 (1.606 points, p = 0.021 ) compared to that in the control group. No obvious adverse effect was reported during this study. Moxibustion using a moxa burner may be an effective and safe intervention for overweight adolescent girls, having both physical and psychological benefits.

Effects of School-Based Exercise and Nutrition Intervention on Body Composition and Physical Fitness in Overweight Adolescent Girls

Regular exercise during school hours is encouraged since childhood obesity has reached epidemic proportions. Moreover, a great majority of adolescents do not meet the recommendations for moderate-to-vigorous physical activity. The present study aimed to determine the effects of school-based high-intensity interval training (HIIT) and nutrition intervention on body composition and physical fitness in overweight adolescent girls. Forty-eight girls were included in the study, of whom 24 (age = 15.5 ± 0.7 years) were randomized to a experimental group (EXP) (HIIT and nutrition intervention school-based program) and 24 (age = 15.7 ± 0.6 years) to a control group (CON) that maintained their usual physical education activities. HIIT consisted of 10 stations of own bodyweight exercise and was done three times per week for eight weeks. Moreover, the EXP participated in the nutrition program led by a nutritionist two times a week. Apart from body composition assessment, participants performed countermovement jump (CMJ), medicine ball throw, hand-grip test, and Yo-Yo Intermittent Recovery Level 1 Test (YYIRT1). A significant effect of group (EXP vs. CON) x time (pre vs. post) interaction was observed for weight [F(1,44) = 7.733; p = 0.008], body mass index [F(1,44) = 5.764; p = 0.020], body fat (in kg) [F(1,44) = 17.850; p < 0.001], and body fat (in %) [F(1,44) = 18.821; p < 0.001]. Moreover, a significant interaction was observed for the medicine ball throw [F(1,44) = 27.016; p < 0.001] and YYIRT1 [F(1,44) = 5.439; p = 0.024]. A significant main effect for time was found for hand grip [F(1,44) = 9.300; p = 0.004] and CMJ [F(1,44) = 12.866; p = 0.001].The present study has demonstrated that just eight weeks school-based HIIT and nutrition intervention, including three sessions a week, can improve body composition and muscular and physical aerobic performance in overweighted adolescent girls.

Change in the Motivation to Receive Treatment by Overweight Adolescent Girls in the Course of Counseling

The purpose of this study was to reveal changes in the motivation to receive treatment by overweight adolescent girls in the course of counseling. Methods and Results: The study included 2 groups of overweight girls with gynecological disorders aged between 14 years and 16 years. Group 1 comprised 20 girls admitted to a hospital for the first time; Group 2 consisted of 20 girls who had undergone treatment earlier (were admitted repeatedly). The motivational-personal sphere was studied using the following methods: (1) McClelland’s method for testing social and psychological activity motivators; (2) S.R. Panteleev’s research method of self-attitude; (3) EAT-26; (4) The body satisfaction method by Collins. The results obtained showed that changing motivation to receive treatment is a complex process implying changes in motivational induction: Achievement Motive, Affiliation Motive, Help Motive, Development Motive, and Cognition Motive. It was also revealed that directly acting motives prevailed over those emerging due to awareness of the treatment’s purpose. Conclusion: a specially developed counseling process comprising diagnostic, informational, correctional and developmental aspects of working with adolescent girls individually and in groups contributed to changing motivation to receive treatment by overweight adolescent girls.

Importance of Self-Efficacy in Eating Behavior and Physical Activity Change of Overweight and Non-Overweight Adolescent Girls Participating in Healthy Me: A Lifestyle Intervention with Mobile Technology

Very little is known about how multicomponent interventions directed to entire populations work in selected groups of adolescents. The aim was to evaluate the effectiveness of the Healthy Me one-year program on changes in healthy eating and physical activity among overweight and non-overweight female students. Randomization involved the allocation of full, partial or null intervention. The randomized field trial was implemented in 48 secondary schools (clusters) all over Poland among 1198 15-year-old girls. In this study, a sample of N = 1111 girls who participated in each evaluation study was analyzed. Using multimedia technologies, efforts were made to improve health behaviors and increase self-efficacy. The main outcome was a health behavior index (HBI), built on the basis of six nutritional indicators and one related to physical activity. HBI was analyzed before and immediately after intervention and at three months’ follow-up, and the HBI change was modeled. Statistical analysis included nonparametric tests and generalized linear models with two-way interactions. Comparing the first and third surveys, in the overweight girls, the HBI index improved by 0.348 (SD = 3.17), while in the non-overweight girls it had worsened. After adjusting for other factors, a significant interaction between body weight status and level of self-efficacy as predictors of HBI changes was confirmed. The program turned out to be more beneficial for overweight girls.

Effect of Psychological Need-Supportive Summer Camp: FIT-Dawg Girls Summer Camp

Physical activity (PA) is a major factor related to obesity risk. Research has shown PA interventions among adolescents to be moderately successful in short-term but limited to longer-term. Self-determination theory (SDT) postulates that a psychological need-supportive environment (i.e. one that supports competence, autonomy, and social relatedness) is effective in maintaining volitional motivation which can lead to sustained positive behavioral changes including PA. Although research has supported the central tenets of the SDT, there is limited evidence examining whether a summer camp intervention can sustain improvements in PA motivation and behavior. Thus, this study examined the acute and 12-weeks longer-term effectiveness of a five-day psychological need-support centered summer camp on healthy weight and overweight adolescent girls’ weight management behaviors. A single-group case series study with pre-, post, and 12-week follow-up-test analyses. A sample comprised 42 (Mage = 11.70±1.12) adolescent females. Exercise motivation, PA intention, and PA and dietary behaviors were measured. The findings showed a between-group effect on daily steps (F(1, 19) = 15.83, p = .001, ?p 2 = .46), moderate-to-vigorous intensity PA (F(1, 19) = 4.58, p = .046, ?p 2 = .19), energy intake (F(1, 19) = 7.23, p = .013, ?p 2 = .27), PA intention (F(2, 18) = 6.25, p = .024, ?p 2 = .28), intrinsic motivation (F(2, 18) = 6.25, p = .024, ?p 2 = .28), and amotivation (F(2, 18) = 16.25, p < .001, ?p 2 = .54). A need-supportive summer camp may be especially effective in improving PA motivation and behavior in overweight girls.

Habitual Breakfast Patterns Do Not Influence Appetite and Satiety Responses in Normal vs. High-Protein Breakfasts in Overweight Adolescent Girls

Differences in postprandial insulin, glucose, and/or free fatty acid concentrations, following the consumption of breakfast, have been demonstrated to be dependent on habitual breakfast patterns. This study examined the effects of habitual breakfast patterns on postprandial appetite, satiety, and hormonal responses along with daily food intake following the consumption of normal-protein (NP) vs. higher-protein (HP) breakfasts in overweight adolescents. Thirty-seven girls (age: 19 ± 1 year; BMI: 29.0 ± 3.4 kg/m2) participated in the semi-randomized crossover design study. Participants were grouped according to whether they habitually skipped (SKIP, n = 18) or consumed breakfast (CONSUME, n = 19), and consumed a NP (350 kcal; 13 g protein) or HP (350 kcal; 35 g protein) breakfast for 3 days/pattern. On day 4, breakfast was provided, and appetite questionnaires and blood samples were collected throughout an 8 h testing day. Daily food intake was also assessed. Regardless of habitual breakfast patterns, the consumption of HP breakfast led to greater daily fullness (29,030 ± 6,010 min × mm) vs. NP breakfast (26,910 ± 5580 min × mm; p = 0.03). Daily protein consumption was greater (98 ± 15 g vs. 78 ± 15 g), and carbohydrate consumption was lower (331 ± 98 g vs. 367 ± 94 g) with HP vs. NP (both, p < 0.001). No other differences were observed. These data suggest that the recommendation to consume a HP breakfast for improved satiety and ingestive behavior is appropriate for overweight adolescent girls, regardless of habitual breakfast patterns.
