Effects of 24-week resistance exercise training on carotid peak systolic and end diastolic flow velocity in healthy older adults

Abstract

[Purpose] The aim of this study was to examine the effect of resistance exercise on carotid intima-media thickness, luminal diameter, peak systolic flow velocity, end diastolic flow velocity, and wall shear rate in healthy elderly men. [Subjects and Methods] Thirty healthy elderly men (age ≥65 years) were randomly divided into a control (n=15) and resistance exercise (n=15) groups. The 24-week exercise intervention consisted of 3 days of resistance exercise per week using an elastic band per week. Body composition, physical function, blood pressure, and carotid variables were measured at baseline and after 24 weeks. [Results] Body fat percent, skeletal muscle mass, systolic blood pressure, grip strength, arm curl, chair stand up, sit and reach, maximum walking speed, time up and go, and two-minute step test showed significant interaction. Peak systolic flow velocity, end diastolic flow velocity, and wall shear rate also showed significant interaction. [Conclusion] A 24-week resistance exercise program, using elastic bands, effectively improves carotid flow velocity and wall shear rate in healthy elderly men.

Intradialytic exercise improves physical function and reduces intradialytic hypotension and depression in hemodialysis patients

“…However, there were cases that had reduced blood pressure [30] or no blood pressure changes [31] after the exercise. Also, the blood pressure decreased [32] or did not alter [33] after anaerobic elastic band exercise.…”

Effects of elastic band resistance training on the physical and mental health of elderly individuals: A mixed methods systematic review

“…Most were published between 2013 and 2022, and the majority were quantitative studies, including 7 quantitative non-randomized studies [ 42 , 46 , 48 , 54 , 58 , 65 , 66 ], 1 quantitative descriptive study [ 39 ], and 17 quantitative randomized controlled trials [ 40 , 41 , 43 – 45 , 47 , 49 – 53 , 59 – 64 ]. The subjects were all 60 or older; six of the studies looked specifically at older women [ 41 , 51 , 52 , 60 , 64 , 65 ], and one specifically at older men [ 44 ].…”

“…Twelve of the 25 quantitative studies measured the effects of elastic band resistance training on upper and lower limb flexibility in older adults. Six were randomized controlled trials [ 40 , 44 , 50 , 52 , 53 , 64 ], five were non-randomized controlled trials [ 46 , 48 , 54 , 58 , 66 ], and one was a quantitative descriptive study [ 39 ].…”

“…Of the ten studies, statistically significant improvement in upper limb flexibility after intervention was noted in seven studies (p<0.05) [ 40 , 46 , 48 , 52 – 54 , 58 ], and a non-significant improvement was noted in three studies [ 39 , 64 , 66 ]. Of the studies measuring lower limb flexibility, eight used the chair sit and reach test [ 39 , 40 , 46 , 52 – 54 , 58 , 64 , 66 ], and two used the sit and reach test [ 44 , 50 ]. All studies found statistically significant improvement in lower limb flexibility after intervention (p<0.05).…”

“…A total of 18 of 25 quantitative studies evaluated the effect of elastic band resistance training on upper and lower limb endurance in older adults. Eleven studies were randomized controlled trials [ 40 , 41 , 43 , 44 , 49 , 52 , 53 , 59 , 60 , 63 , 64 ], six were non-randomized controlled trials [ 42 , 46 , 48 , 54 , 58 , 65 ], and one was a quantitative descriptive study [ 39 ]. Sixteen of the studies assessed the effect of elastic band resistance training on upper and lower limb endurance in older adults using the 30-s arm curl test and the 30-s chair rise test [ 39 – 44 , 46 , 48 , 49 , 52 , 53 , 59 , 60 , 63 – 65 ], and two studies used the 60-s chair rise test [ 54 , 58 ].…”
