Renal Insufficiency, Chronic

Interventions

This is a two-arm, randomized, controlled clinical trial. There will be no masking. The sample will consist of 32 resident high school students from the Federal Institute of Rondônia (Ariquemes Campus

21 participants will be allocated to the Exercise Group and 11 to the Control Group. Participants in the Exercise Group will undertake a combined physical exercise program consisting of resistance and

s capacity. Following the resistance exercises, aerobic exercises will be performed on a treadmill or stationary bicycle, with a progressive duration of 15 to 20 minutes and an intensity corresponding

Exclusion criteria

Exclusion criteria: Psychological disorders preventing comprehension of research procedures; lower-limb amputation or disability; pregnancy; high cardiovascular risk; musculoskeletal complications contraindicating physical exercise; issues identified in the Physical Activity Readiness Questionnaire (PAR-Q) that contraindicate participation; or any clinical condition or other relevant factor identified by the researchers that could compromise participant safety or interfere with the implementation of the intervention and assessments

Design outcomes

Primary

Measure	Time frame
Expected outcome 1: An increase in glomerular filtration rate is expected, estimated by measuring serum cystatin C concentration using the Pierce equation, assessed at the beginning of the first two months and at the end of the second two months after sixteen weeks of combined physical exercise intervention	—

Secondary

Measure	Time frame
Expected outcome 1: A reduction in glycated hemoglobin, assessed using an immunoturbidimetric method certified by the National Glycohemoglobin Standardization Program, is expected to be observed between the beginning of the first two-month period and the end of the second two-month period;Expected outcome 2: An increase in high-density lipoprotein concentration, determined by an automated enzymatic method, is expected at the beginning of the first two-month period and at the end of the second two-month period;Expected outcome 3: A reduction in low-density lipoprotein concentration, determined by an automated enzymatic method, is expected at the beginning of the first two-month period and at the end of the second two-month period;Expected outcome 4: A reduction in systolic blood pressure measured by sphygmomanometry is expected at the beginning of the first two months and at the end of the second two months;Expected outcome 5: A reduction in diastolic blood pressure measured by sphygmomanometry is expected at the beginning of the first two months and at the end of the second two months;Expected outcome 6: Increased muscle mass and reduced body fat percentage, as assessed by bioelectrical impedance analysis, are expected at the beginning of the first two months and at the end of the second two months;Expected outcome 7: It is expected that there will be a reduction in abdominal circumference and an improvement in the waist-to-height ratio and waist-to-hip ratio, as assessed by anthropometry, at the beginning of the first two months and at the end of the second two months;Expected outcome 8: It is expected that urine specific gravity will remain within normal values ??as assessed by refractometry at the beginning of the first two months and at the end of the second two months;Expected outcome 9: A reduction in anxiety symptoms, as assessed by the Depression, Anxiety, and Stress Scale for Adolescents, is expected at the beginning of the first term and at the end of the	—
