Height, body mass, and body fat percentage were measured prior to and at the end of each program. Height was measured in centimeters using a wall-mounted altimeter to the nearest 0.1 cm, while weight was measured using an Omron Karada Scan (model HBF-356) to the nearest 0.1 kilogram (kg). When being measured, participants were allowed to wear only light clothing and no shoes. BMI was calculated by dividing weight (kg) by height (square meter (m²)) and classified according to the World Health Organization criteria: normal weight (18.5–24.9 kg/m2), overweight (25.0–29.9 kg/m2), and obese (>30 kg/m2).31 Body fat percentage was measured according to the bio-impedance analysis technique using an Omron Karada Scan (model HBF-356). WC and HC were measured using a measuring tape to the nearest 0.1 cm. WHR was calculated according to the ratio between WC and HC. Fat mass was calculated by multiplying body weight by body fat percentage, and lean body mass (LBM) was calculated by subtracting the fat mass from total body weight.
Karada scan
Manufactured by Omron
Sourced in Japan
The Karada Scan is a self-measurement device designed to provide users with information about their body composition. It uses bioelectrical impedance analysis (BIA) technology to measure parameters such as body weight, body fat percentage, muscle mass, and other related metrics. The Karada Scan is a compact and portable device that allows users to track their health and fitness progress over time.

The participants' height was measured using a stadiometer (Seca, Hamburg, Germany) while they were in a standing position with shoulders and hips against a wall and without shoes. Weight was measured using a digital scale (808Seca, Germany) while wearing light clothes and without shoes and recorded to the nearest 0.1 kg. Body mass index (BMI) was calculated by dividing weight by height squared and expressed in kg/m2.
The waist circumference (WC) was measured according to a standard protocol using a tape measure placed between the lower rib and iliac crest. Waist circumference (cm) was then divided by hip circumference to determine the waist-to-hip ratio (WHR) (cm). Muscle mass, body fat mass, and visceral fat percentage were evaluated using bioelectric impedance analysis (Omron KaradaScan).

Body composition measurement included weight, BMI, TF, SF, SMM, and VF. Body composition was evaluated using the Omron Karada Scan Body Composition & Scale (HBF-701). It consists of eight-contact electrodes at an anatomical landmark, namely both footpads and handles. BIA analyzers introduce a small electrical current into the body and measure the impedance to current flow. The Omron Karada Scan uses an electrical current of 50 kHz, 500 μA. Participants refrained from consuming food, tea, coffee, alcohol, and smoking. They were also restricted from performing strenuous physical activities for at least 2 h before the body composition examination.29 Participants wore loose and comfortable clothing that did not consist of metallic or electronic items. The hands and feet of each participant were clean and dry before handling the instrument. Measurement was taken from the person's standing position, with their arm at a 90° angle with the body.

During both sessions, the students filled out a questionnaire regarding background variables that could influence their cognitive performance and/or physical activity behavior. Health and medical issues, including medication use, were measured via a short questionnaire.
Medication use was categorized as not reported, directly impairing cognitive performance, indirectly impairing cognitive performance by potentially causing sleepiness, dizziness, or a headache, or, unknown to affect cognitive performance. Learning disabilities were asked in a similar manner and were categorized as not reported, or, potentially related to cognitive performance. Disabilities that affected PAB were also asked in a similar manner and were categorized as either reported or not reported. Participants also indicated whether they had color-blindness. Height was measured in meters. Weight, visceral fat, fat, and muscle percentages were measured without shoes, with empty pockets and heavy vests or sweaters removed with the KaradaScan, a body composition monitor (Omron, BF511). Height and weight were used to calculate body mass index (BMI; i.e., weight in kilograms divided by height in meters squared). Visceral fat (fat around organs) is measured on a scale ranging from 1–30, where 1–9 is normal, 10–14 is high, and 15–30 is very high.

Body composition was measured at the end of the dietary data collection period. Body mass (to the nearest 0.1 kg) and body fat percentage were measured using a portable bioelectrical impedance monitor (Karada Scan, model HBF-362, Omron, Osaka, Japan). Participants were dressed in light clothing and bare-footed when the measurement was taken. Participants provided a self-reported estimate of height.

After entering age, gender and height taken by stadiometer subject were allowed to stand on the instrument after its calibration. A digital, portable noninvasive instrument Omron KaradaScan ( Model HBF-510, Japan) working on principle of tetrapolar bioelectrical impedance analysis was used that passes electric current of 500 μAmp at frequency 5 kHz to scan the whole body to derive regional body composition.

Four-electrode bioelectric impedance analyzer (HBF-362 Omron Karada Scan) was used to measure the total body fat percentage and visceral fat levels. It was ensured that the participants did not consume food or water for at least 1 hour prior to the measurement. Test–retest reliability examined in the present study for total body fat percentage and visceral fat levels was found to be excellent with standard measurement errors ranging from 0.8% to 2% and 0.5% to 1.5%, respectively.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
