Walnut consumption while doing concurrent training improves strength, sleep quality, standing support, cognitive performance and postural balance in elderly men.
Randomised Controlled Trial Sleep Walnut
In the study, twenty healthy elderly men were grouped into two randomly controlled cohorts. There were three training sessions per week featuring a concurrent combination of strength and endurance training. One group received a diet supplemented with 15 grams per day of walnuts (CTW) over six weeks while the other didn't (CT). Their strength, sleep quality, cognitive performance and postural balance were evaluated using an isokinetic strength test, Spiegel questionnaire, Montreal cognitive assessment and balance measurements respectively, 48 hours before and after the intervention period.
The results pointed that both groups experienced significant improvements in strength and sleep quality with CTW showing a greater increase in sleep quality. CTW group showed improvements in cognitive performance and postural balance while CT group did not see these benefits. Hence it's observed that combination of concurrent training and walnut consumption was found to be effective in improving strength, sleep quality, cognitive performance and postural balance in elderly men.
