Effects of Concurrent Training on Serum PCSK9 Levels in Adults With Overweight
Effects of Concurrent Training on Serum PCSK9 Levels in Adults With Overweight: A Randomized Controlled Trial
Being overweight can increase the risk of heart disease. PCSK9 is a protein that helps regulate cholesterol levels in the blood. Exercise may affect PCSK9 levels, but previous studies have reported conflicting results.
The purpose of this study is to determine whether a program combining aerobic exercise and resistance training changes blood PCSK9 levels in adults with overweight. The researchers will also examine changes in blood cholesterol levels and body composition.
A total of 42 adults aged 18-40 years with overweight will be randomly assigned to one of two groups. One group will participate in a supervised exercise program three days per week for eight weeks. Each session will last approximately 60 minutes and include aerobic exercise, resistance training, warm-up, and cool-down periods. The other group will continue their usual daily activities without participating in a structured exercise program provided by the study.
Blood samples and body measurements will be collected before the program, after four weeks, and after eight weeks. Participants will also record their usual food intake and physical activity during the study.
The researchers expect that the combined exercise program may reduce blood PCSK9 levels compared with maintaining usual daily activities. The findings may help improve understanding of how exercise affects cholesterol regulation in adults with overweight.

Подробное описание
Background and Rationale
Overweight is associated with an increased risk of cardiovascular disease, partly through adverse changes in blood lipid levels. Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a protein involved in cholesterol regulation. It binds to low-density lipoprotein receptors (LDLR) and promotes their degradation, thereby reducing the removal of low-density lipoprotein cholesterol (LDL-C) from the bloodstream.
Regular exercise is an important lifestyle strategy for improving cardiovascular health and lipid metabolism. Previous research suggests that exercise may influence circulating PCSK9 levels, potentially contributing to changes in cholesterol regulation. However, studies investigating the effects of physical activity and exercise on PCSK9 have reported conflicting findings, with some showing reductions and others reporting increases. Therefore, the effects of structured exercise training on circulating PCSK9 levels remain unclear.
Study Objectives
The primary objective of this study is to investigate the effects of an eight-week concurrent aerobic and resistance training program on serum PCSK9 levels in adults with overweight, compared with a control group maintaining their usual daily activities.
The study will also examine changes in blood lipid levels, glucose concentrations, anthropometric measurements, and body composition. Additionally, the relationship between serum PCSK9 levels and body composition will be investigated.
Study Design and Procedures
This study is designed as a single-center, two-arm, parallel-group randomized controlled trial. Participants will be randomly allocated to either a supervised concurrent training group or a non-exercising control group using block randomization with a 1:1 allocation ratio.
The exercise program will combine aerobic and resistance training under professional supervision. Participants in the control group will be asked to maintain their usual daily activities without receiving a structured exercise intervention.
Biochemical, anthropometric, and body composition assessments will be performed at baseline, 4 and 8 weeks after baseline. Blood samples will be collected after an overnight fast to assess serum PCSK9 and metabolic markers.
To help account for potential changes in lifestyle behaviors, dietary intake and habitual physical activity will be monitored throughout the study using three-day dietary records and three-day physical activity records at the specified assessment periods.
Expected Contribution
This study is expected to provide evidence regarding the effects of concurrent aerobic and resistance training on circulating PCSK9 levels in adults with overweight. The findings may contribute to a better understanding of the relationship between exercise, PCSK9, and cholesterol metabolism and may help inform future research on exercise-based approaches to cardiovascular risk management.

Экспериментальный: Concurrent Training Group
Participants assigned to this group will perform supervised concurrent aerobic and resistance training three times per week for eight weeks. |
Participants in the intervention group will complete an eight-week supervised concurrent aerobic and resistance training program, consisting of three sessions per week. Each 60-minute session will include a 5-minute warm-up, 25 minutes of aerobic exercise, 25 minutes of resistance exercise, and a 5-minute cool-down. Aerobic exercise will be performed on a treadmill or cycle ergometer at 40-60% of heart rate reserve. Resistance training will include eight exercises targeting major muscle groups: chest press, lat pull-down, hamstring curl, quadriceps extension, shoulder press, biceps curl, triceps extension, and abdominal crunch. Participants will perform two sets of 8-16 repetitions at 50-80% of their 10-repetition maximum, with approximately one minute of rest between sets. All sessions will be conducted under professional supervision. Heart rate and perceived exertion will be monitored during exercise using a heart rate monitor and the Borg Rating of Perceived Exertion Scale. |

Без вмешательства: Control Group
Participants assigned to the control group will not receive a structured exercise intervention. They will be instructed to maintain their usual physical activity, dietary habits, and daily routines throughout the eight-week study period. |
