Clinical Trial Summary

According to sample size calculation and after achieving the inclusion criteria, sixty patients with non-alcoholic fatty liver (NAFL) of both genders will be enrolled in this study and their ages will be ranged from30s-40s; they will be selected from internal medicine-outpatient clinics, Cairo University Hospitals; they will participate in the study for 8 weeks, and randomly be assigned into two equal groups in number.

Group (A) (n =30) will receive calisthenics exercise three times /week for eight weeks, group (B) (n =30) will receive HIIT for three times /week for eight weeks and all patients in both groups will receive their prescribed medication (Statin 5mg ).

Description:

A) Evaluation equipment:

All patients will be evaluated before and after treatment protocol.

1. Body composition analyzer (in body 230):- It will be used for estimating body composition, to measure the percentage of the body free fat mass, lean body mass and body mass index (BMI).

Fig (1) Body composition analyzer (in body 230)

2. Mercury and digital sphygmomanometer and stethoscope: it will be used to measure blood pressure. (Niscomed PW-216)

3. Pulse oximeter: It will be used to monitor heart rate and oxygen saturation continuously during exercise (SantaMedical Generation 2 Fingertip).

Fig (2) Pulse oximeter

4. Bruce protocol:-to assess functional capacity (Vo2) max and intensity of exercise.

5. Tape measurement: - to assess waist circumference, waist / hip ratio.

6. Clini-chem 2 analyzer: - to analyze blood lipid profile and liver enzymes.

Fig (3) Clini-chem 2 analyzer

7. Abdominal Ultrasonography (USG) (Siemens, ACUSON NX3 ELITE, and German):- to measure size of the liver, thickness of fat outside liver, as well as severity of the fat infiltration.

8. International Physical Activity Questionnaire-Short Version (IPAQ)):- to assess level of physical activity that patients do as part of their daily lives.

9. Borg scale: - to estimate effort, exertion, breathlessness and fatigue during physical work.

B. Training equipment:-

• A motorized treadmill device (KETTLER, laufband alpha run 600, German) with a minimum speed of 0.5km/hr and capability to display the distance in kilometer per hour will be used in this study.

• Weighted vest progressions and elastic bands: - for calisthenics exercise. -Procedure of the study:- -Assessment procedure:-

A) History and physical examination:

Complete history taking will be conducted to collect data about patient's general condition, physical activity, current medication, and measuring blood pressure.

B) Anthropometric measurement:

1. Body composition analysis: - By using body composition analyzer device (In body 230). The patient will put off his shoes and socks and stand on the device. The device measures his weight and height automatically then the patient will hold the arms of the device to measure total body fat (free fat mass), lean mass and body mass index (BMI). Free fat mass (FM) % 18-24%for men; 25-31%for women and lean mass (LBM) for men 76-82%; for women 69-75% according to The American Council on Exercise (ACE) .

2. Waist circumference (WC) and Waist to hip ratio (WHR):-: Placing a tape horizontal in the midpoint between iliac crest and last rib, and take the measure just after expiration.

Hip circumference will be measured from the widest point of the hip; then dividing waist circumference by hip circumference to calculate waist to hip ratio. According to world health organization, normal cut off values of waist circumference (WC < 88 cm for men; WC < 102 cm or less for women) and waist to hip ratio (WHR < .95 cm for men ; WHR < .80 cm for women).(World Health Organization .2000) 3- Functional capacity (VO2 max):- Using Bruce protocol for multistage treadmill testing of maximal exercise testing will be used as the following 3-min stages: Stage I (2 mph, 10% grade), Stage II (2.5 mph, 12% grade), Stage III (3.4 mph, 14% grade), and Stage IV (4.2 mph, 16%). (Bruce et al., 1963) VO2 max will be estimated from treadmill time based on following equation: For Men VO2 max = 14.8 - (1.379 x T) +(0.451 x T²) - (0.012 x T³) For Women VO2 max = 4.38 x T - 3.9 T = Total time on the treadmill measured as a fraction of a minute i.e.: A test time of 9 minutes 30 seconds would be written as T=9.5 .(Khurana and Oommen 2016) C) Liver enzymes analysis:- According to American Gastroenterological association ,the normal values of liver enzymes (alanine amino transferase ( ALT) 7-55 U/L, aspartate aminotransferase (AST) 8-48 U/L ,gamma glutamyl transferase (GGT) 9-85U/L ). (American Gastroenterological association. 2002)

D) Blood lipid profile analysis:- According to The National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III), the normal reference range of lipid profile (total cholesterol < 200 mg\dl, low- density lipoprotein cholesterol (LDL-C) <100 mg\dl, triglyceride (TG) <150 mg\dl, high density lipoprotein cholesterol (HDL-C) ≥60mg\dl, LDL/HDL3.5/1 mg\dl). (Cleeman et al., 2001) E) Abdominal Ultrasonography (USG):- A 10 MHZ sonosite 180 plus US sanner (penetration depth of 2.2 cm) will be used, Ultrasonographic findings in the liver will be as the following:-

• Increase in hepatic echogenicity.

• Decreased penetration of the deep part of the liver.

• Decreased echogenicity of the diaphragm and intrahepatic portal vessels. (Ma et al., 2011)

F) The International Physical Activity Questionnaire-Short Version (IPAQ)):-It is self - report questionnaire, It consists of seven Open-ended questions surrounding individuals' last seven-day recall of physical activity. The IPAQ records the activity of four intensity levels: 1) vigorous-intensity activity such as aerobics, 2) moderate-intensity activity such as leisure cycling, 3) walking, and 4) sitting. Appendix II G) Borg scale: - It is a scale of 0-10;. The scale will allow individuals to subjectively rate their level of exertion during exercise or exercise testing. Appendix III (2) Treatment procedure:- Group (A):- that included 30 non-alcoholic fatty liver patients will participate in calisthenics exercise for eight weeks, Three times/week based on the following program:-

Exercise prescription:

• Mode of exercise: Strengthening exercise.

• Modality of exercise: Bodyweight exercises and require little equipment.

• Forms of exercises:

1. Sit-Ups that work on Lower abs, mid abs, upper abs, hip flexors, chest, shoulders, quads, and hamstrings.

• Duration: 5-10 minutes warming-up in the form of simple stretching exercises .This is followed by the active phase (20 to 30 minutes) during which a 5-10 seconds passive rest will be allowed in-between repetitions and 1-2 minute passive recovery will be permitted in-between sets. There will be also a cooling down phase for 5 minutes simple stretching exercises.

• Frequency: 3 days/week for 8 weeks.

• Progression: the exercise program will be progressed gradually by increasing the number of sets, repetitions and by using elastic bands and weighted vest progression.

Group (B): that included 30 non-alcoholic fatty liver patients will participate in high intensity interval training on treadmill for eight weeks, three times/week based on the following program:-

1. Warming up period for 5 min at intensity corresponding to 65-75% of heart rate maximum (HRmax).

2. Training phase for 30 min divided into four sets of 4-min length each at intensity equals 85- 90% of HRmax interspersed by 3 minutes low intensity walking at the level of 65-75% of HRmax.

3. Cooling down period for 5 min of at 50-60% of the HRmax. (El-Deeb et al., 2018)

All patients will be trained at the lower intensity limit for the first 2 weeks of the program before increasing the intensity levels toward the upper limit.
