As per a recent study by researchers it is found that moderate-intensity exercise such as brisk walking, water aerobics or cycling can have the most beneficial effect on memory performance. These findings, published in the journal Neurobiology of Learning and Memory, suggest that it is not necessary for people to carry out highly strenuous exercise to achieve observable improvements in long-term memory, as moderate exercise can have a more positive influence.
For the study, three experiments were performed, each with a three-armed crossover design measuring the extent to which physical exercise and wakeful rest can influence long-term memory performance.
In experiment 1, the effects of continuous moderate-intensity exercise, passive rest (no cognitive engagement) and active rest (cognitively engaged) were explored.
In experiment 2, continuous moderate-intensity exercise was compared to a type of high-intensity interval training (HIIT) and passive rest. Experiment 3 observed the effects of low, moderate, and high-intensity continuous exercise.
