Comparison between walking and moderate to vigorous physical activity: the association with metabolic syndrome components in older adults.

ABSTRACT:

Objectives

The purpose of this study was to compare moderate-to-vigorous physical activity (MVPA) with walking in terms of the association with metabolic syndrome components in Korean older adults.

Methods

A total of 1,388 older adults (age?65 years) from the Korea National Health And Nutrition Examine Survey 2018 were included in this study. MVPA time and walking time per week were used as physical activity variables and blood pressure, waist circumference, glucose, high-density lipoprotein, and triglyceride were used as metabolic syndrome components. Partial correlation, analysis of covariance, and multinomial logistic regression were used for statistical analysis after adjusting for age, sex, smoking, and alcohol consumption.

Results

High-density lipoprotein was significantly higher in the MVPA low/walking high and MVPA high/walking high group compared to the MVPA low/walking low group. Triglyceride was significantly lower in the MVPA high/walking high group compared to MVPA low/walking low and MVPA low/walking high group. If MVPA was less than 150 min/week the likelihoods to have abnormal blood pressure and metabolic syndrome were 1.8 times and 1.9 times higher than MVPA more than 150 min/week, respectively. If walking was less than 180 min/week the likelihood to have abnormal high-density lipoprotein was 1.3 times higher than walking more than 180 min/week.

Conclusion

Not only MVPA but also walking is significantly associated with metabolic syndrome components in Korean older adults. Considering the preference and exercise barriers among older adults, walking should be considered as an essential component of the physical activity guideline to prevent chronic diseases in older adults.

Project description:The positive association between the total duration of physical activity and performances of physical function may vary at different times of the day as circadian rhythm regulates individuals in response to external stimulations. We aimed to examine the association of timing-specific and overall moderate-to-vigorous physical activity (MVPA) with performances of physical function in older adults. A cross-sectional analysis was conducted among 118 older adults (mean age?=?70.0?±?5.0 years). We assessed and identified timing-specific (morning: 06:01-12:00; afternoon: 12:01-18:00; evening: 18:01-24:00) and overall MVPA using a triaxial accelerometer. Different measures of physical function were evaluated including handgrip strength (by grip dynamometer), gait speed (5-m walk test), basic functional mobility (timed up and go test), and lower limb strength (five times sit-to-stand test). Multivariate linear regression models adjusting for covariates were used to investigate the associations. Participants spent 25.0 (±?26.2) minutes in MVPA per day on average, half the time spent during the morning (47.7%), followed by during the afternoon (29.9%) and evening (21.6%). The time spent on overall MVPA was generally associated with better physical function performances. There was statistical evidence for the percentages of MVPA engagement during the morning [B?=?0.214, 95% confidence interval (CI) 0.001 to 0.428] and afternoon (B?=?-?0.273, 95% CI -?0.518 to -?0.027) associated with basic functional mobility but with contrary directions; the percentage of MVPA engagement during the evening was associated with less time spent in gait speed performance (B?=?-?0.237, 95% CI -?0.468 to -?0.006). Our findings inform implications that the overall MVPA engagement was more important than timing-specific MVPA to older adults' physical function performances. Strategies for accumulating time of MVPA is more practical and effective than encouraging to engage MVPA in specific timing for the enhancement of functional ability and therefore prevent disability among older adults.

Project description:BACKGROUND:Adults and older adults are recommended to engage in 150 minutes of moderate (MPA) to vigorous (VPA) aerobic physical activity (MVPA) per week, with the heuristic message of 3000 steps in 30 minutes (100 steps per minute [spm]). However, this message is based on adult populations, with a paucity of research on step-rate thresholds that correspond to absolute MVPA (moderate=3 metabolic equivalents [METs], vigorous=6 METs) and relative MVPA (moderate=40% estimated METmax, vigorous=60% estimated METmax) in older persons, who have lower stride lengths and a lower exercise capacity. Also, there is a need to consider the influence of anthropometric differences when quantifying the relationship between step rate and intensity-related physical activity. OBJECTIVE:This study assessed absolute and relative MVPA step-rate thresholds and anthropometric factors (ie, height, leg length, and body mass index [BMI]) in older adults. METHODS:Nineteen older adults (7 females; age 69 years, SD 2, BMI 26 kg/m2, SD 4) completed a staged treadmill walking protocol: six minutes at 2.4, 3.2, 4.0, 5.6, and 6.4 km/h. Steps were manually counted and volume rate of oxygen consumed (VO2) was measured via indirect calorimetry. Aerobic fitness was estimated via the submaximal single-stage treadmill protocol. RESULTS:When BMI was considered, mixed effects modeling revealed absolute and relative MPA step-rate thresholds of 108 spm and 117 spm, respectively. Absolute and relative VPA corresponded to step rates of 135 spm and 132 spm, respectively. Neither height nor leg length improved the ability of the model to predict stepping cadence from METs. CONCLUSIONS:In general, older adults need to walk faster than 100 spm (ie, approximately 110 spm) to reach MPA and in excess of approximately 130 spm to achieve VPA, depending on BMI status. Health care professionals and researchers should adjust cadence-based recommendations for differences in BMI in their older patients and consider using relative intensity to most appropriately tailor their physical activity recommendations.
