It has been associated to a higher risk of cardiovascular diseases, diabetes type II, difficulties in breathing, and osteoarthritis. Studies suggested that daily physical activity, dietary behaviors and genetic influences were the main factors determining weight gain. This study aimed to investigate the relationship between the daily physical activity, food consumptions, and weight gain among King Faisal University (KFU) students. 290 subjects were recruited from 4 colleges of the KFU by systematic random sample from 1120 students enrolled in the course "Health and Fitness'' one of the university mandatory requirements. For each subjects, anthropometric characteristics were measured, daily physical activity was assessed using pedometer, and dietary behaviors were evaluated using a survey questionnaire developed for this study. The validity and reliability of this questionnaire were established before testing. Results noted that the prevalence of overweight and obesity among KFU students was 38.27% with 13.1% obese and 26.9% overweight. Data indicated also that subjects had greater susceptibility to be obese if they are engaged in a daily physical activity lesser than 5000 steps/day, consumed vegetables and fruits lesser than five times/week, and used sugar-sweetened drinks and French fries/potato chips more than five times/week. In conclusion this study noted that KFU students were less obese than other Saudi subgroups. Nevertheless, a specific program may be proposed to implement the theoretical knowledge, including limiting the use of fast foods and sugar-sweetened drinks, and increasing vegetables consumption and the daily physical activity.

However, the feasibility of this approach is problematic. This study aims to compare two multidisciplinary programs used to improve weight loss. Methods: Fifty-two obese individuals were subjected to an Enhanced Lifestyle Counselling associated with, according to their own choice, dieting (N ¼ 11), or dieting þ aerobic training (n ¼ 18), or dieting þ resistance training program (n ¼ 23). The study experiment spanned 16 weeks divided into two phases. The first phase lasted 04 weeks and was oriented to enhance motivation and establishing changes in behaviours related to dietary and sedentary lifestyle. The second phase lasted 12 weeks and was oriented to add aerobic or resistance training. Body compositions, cardiovascular disease risk factors, and cardio-respiratory fitness were assessed. Results: Data demonstrated that all obesity treatment programs were able to improve all studied variables. Weight loss levels were À6.03 ± 2.08, À10.5 ± 2.33, and À9.37 ± 1.99 kg in Dieting, DAT and DRT groups, respectively. Our results noted also that exercise training could play an important role in reducing obesity and its consequences. Nevertheless, modifications were more important in DRT at the explosivity and muscle strength and in DAT at fat percentage, aerobic capacity, SA, and CVR factors. Conclusion: The current evidence noted that both multidisciplinary weight loss programs were efficient in the treatment of obesity and its comorbidity. Moreover, the use of aerobic exercises was more effective in reducing body fat and improving cardiorespiratory fitness. However, using resistance exercises appeared to be more appropriate to enhance the muscle potential.

and treating metabolic syndrome (MetS). This randomized trial aims to examine the effectiveness of a
weight reduction intervention based on caloric restriction, low-impact aerobics (LIA), and a resistancetraining
program in improving body composition, metabolic parameters and cardiovascular disease
(CVD) risk factors among obese students diagnosed with MetS.
Methods: In all, 23 male participants, aged 19e24 years, were randomly introduced to a dieting program
(the diet group, or DG ¼ 09) or to dieting associated with a supervised physical training program (the
diet plus training group, or DTG ¼ 14). Before and after the intervention, the participants’ anthropometric
measures and cardiovascular disease risk factors were assessed.
Results: Following the diet-based intervention, significant improvements were noted in BMI (p ¼ 0.39),
PBF (p ¼ 0.022) and LDL-c (p ¼ 0.024). However, in response to the diet plus aerobic and resistance
exercise intervention, obese participants had significant reductions in body weight (p ¼ 0.018), WC
(p ¼ 0.042), BMI (p ¼ 0.001), BFP (p < 0.001), DBP (p ¼ 0.013), SBP (p ¼ 0.016), TG level (p ¼ 0.026), TC
(p ¼ 0.016), LDL-c (p ¼ 0.001) and VLDL-c (p ¼ 0.026). Notable differences were also observed between
groups in terms of changes inWC (p ¼ 0.003), BFP (p ¼ 0.05), WHR (p ¼ 0.029), FBG level (p ¼ 0.022), TG
level (p ¼ 0.001), TC (p ¼ 0.006), LDL-c (p ¼ 0.014) and VLDL-c (p < 0.001).
Conclusion: Diet-based intervention could be an effective tool in reducing body composition and some
MetS components. However, adding three weekly aerobic and resistance-training sessions to the dieting
program may deliver better outcomes, particularly in terms of reducing WC, BFP, WHR, FBG level, TG
level, TC, LDL-c, and VLDL-c.

Crowd-Reflecting: A Counterproductive Experience of Arab Adult Learning Via Technology Abstract T... more Crowd-Reflecting:
A Counterproductive Experience of Arab Adult Learning Via Technology
Abstract
This methodological piece theorises the limitations of transitioning reflection from individualistic to participatory practice. It addresses the question: what are the challenges of introducing ‘crowd-reflecting’ into Arab academia? To answer this, 140 Arabs from an academic organisation were invited to ‘crowd-reflect’, online, on their institution, using a five-phase model. The data analysis showed that crowd-reflecting was challenged by limited ‘cultures’ of collaboration, healthy conflict, cross-gender communication, integrity and critical thinking in Arab academia. Despite implementing strategies to overcome these challenges, crowd-reflecting resulted in chaos at the institution, forcing management to intervene to stop the project. This chaos was because crowd-reflecting, unlike individualistic reflection, entailed numerous individuals and intersubjectivity—which complicated reflectiveness, turned thoughtful Arab individuals into a ‘mob’ and jeopardised the well-documented gains of individualistic reflection. Although crowd-reflecting was initiated to improve organisations, it ripped apart organisational soul, turning the institution into a ‘counter-learning organisation’ and leading it over a cliff. This implies that, in Arab academia, beyond micro-level small groups, the more participants there are in reflection, the less effective the learning outcomes may be. In Arab academia, meso-level reflection (and, by implication, macro-level reflection such as the ‘mega-reflecting’ of the Twittersphere) can risk ruining the ‘art’ of reflectiveness.
