Resistance Training and Fish Oil May Help Improve Strength and Blood Pressure
As we age, we lose muscle mass. This leads to declines in muscular strength, metabolic rate, and respiratory function. A recent study suggests that resistance training combined with fish oil supplementation may help mature adults enhance strength and improve blood pressure.
Twenty-eight healthy adults with an average age of 66 participated in the study. They were divided into three groups: control, resistance training only for 12 weeks, and resistance training with fish oil containing 2,100 mg EPA and 720 mg DHA for 12 weeks. The researchers evaluated handgrip strength, physical function, timed up and go, sit to stand, a six-minute walk, and blood pressure at baseline and at the end of the study.
Handgrip strength increased by 5.3% in the resistance training only group, and by 9.4% in the fish oil group. It decreased by 3.9% in the control group. All physical function outcomes increased in the resistance training and fish oil groups. The control group saw a decrease in timed up and go and sit to stand.
In addition, blood pressure significantly improved in the fish oil group, with a 7.8 mmHg decrease in systolic blood pressure and a 4.5 mmHg decrease in diastolic blood pressure. No change in blood pressure was seen in the control group or the resistance training group.
The study was conducted by researchers from New Mexico State University and California State Polytechnic University. It was published online ahead of print on July 9, 2019 in the journal Sports.
