Why they did it?
A poor blood lipid (fat) profile is referred as dyslipidaemia, and is strongly related to cardiovascular disease and other health complications (stroke, peripheral artery disease etc.). Common dyslipidaemia-related biomarkers include; low-density lipoprotein (LDL) aka ‘bad’ cholesterol, high-density lipoprotein (HLD) aka ‘good’ cholesterol and triglycerides. Regular exercise is known to decrease the risk of dyslipidaemia. However, the mode, intensity and duration of exercise needed to reduce the risk of dyslipidaemia have not been well quantified. The purpose of this research was to review the published studies to establish which mode and type of exercise has the most favourable effects on blood lipid profile.
How they did it?
These authors conducted a literature search of published studies examining the blood lipid response to exercise in three population groups; 1) healthy adults, 2) adults with dyslipidaemia and 3) adults with dyslipidaemia and limited mobility (disabled, elderly populations etc.). The specific exercise modes examined were;1) aerobic exercise, 2) resistance training and 3) combined aerobic and resistance training. A total of 13 intervention studies and two review articles meet the inclusion criteria and were included in the final analysis.
What they found?
An analysis of the studies resulted in with the following recommendations:
Healthy adults
- Physical activity for 30 minutes/day, 5 times weekly of prolonged MPA exercise combined with low-intensity resistance training at 50% one repetition maximum (RM)
Adults with dyslipidaemia
- Physical activity for 30 minutes/day, 5 times weekly of prolonged MPA and VPA exercise combined with high-intensity resistance training at 75-80% of RM
Adults with dyslipidaemia and limited mobility
- Engage in physical activity as much as feasible and encourage circuit sessions which include moderate intensity resistance training progressing from 50 to 75 % RM in major muscle groups.
Ok, what does this mean to me?
Depending on the population group, there are different training modes, frequencies and intensities used in the prevention and treatment of dyslipidaemia. Clients wishing to assess their risk of dyslipidaemia should ask their GP for a full a blood lipid profile. The recommendations presented here may be useful in determining exercise delivery to clients depending on their dyslipidaemia and mobility status. Client risk profile should always be measured using a recognised pre-exercise screening protocol and referred for guidance on exercise programming where appropriate.
