While cardiorespiratory fitness is strongly related to survival, there are limited data regarding musculoskeletal fitness indicators. Our aim was to evaluate the association between the ability to sit and rise from the floor and all-cause mortality.

Retrospective cohort.

2002 adults aged 51-80 years (68% men) performed a sitting-rising test (SRT) to and from the floor, which was scored from 0 to 5, with one point being subtracted from 5 for each support used (hand/knee). Final SRT score, varying from 0 to 10, was obtained by adding sitting and rising scores and stratified in four categories for analysis: 0-3; 3.5-5.5, 6-7.5, and 8-10.

Median follow up was 6.3 years and there were 159 deaths (7.9%). Lower SRT scores were associated with higher mortality (p < 0.001). A continuous trend for longer survival was reflected by multivariate-adjusted (age, sex, body mass index) hazard ratios of 5.44 (95% CI 3.1-9.5), 3.44 (95% CI 2.0-5.9), and 1.84 (95% CI 1.1-3.0) (p < 0.001) from lower to higher SRT scores. Each unit increase in SRT score conferred a 21% improvement in survival.


Musculoskeletal fitness, as assessed by SRT, was a significant predictor of mortality in 51-80-year-old subjects. Application of a simple and safe assessment tool such as SRT, which is influenced by muscular strength and flexibility, in general health examinations could add relevant information regarding functional capabilities and outcomes in non-hospitalized adults.

Hypertension, or the chronic elevation in resting arterial blood pressure (BP), is a significant risk factor for cardiovascular disease and estimated to affect ~1 billion adults worldwide. The goals of treatment are to lower BP through lifestyle modifications (smoking cessation, weight loss, exercise training, healthy eating and reduced sodium intake), and if not solely effective, the addition of antihypertensive medications. In particular, increased physical exercise and decreased sedentarism are important strategies in the prevention and management of hypertension. Current guidelines recommend both aerobic and dynamic resistance exercise training modalities to reduce BP. Mounting prospective evidence suggests that isometric exercise training in normotensive and hypertensive (medicated and non-medicated) cohorts of young and old participants may produce similar, if not greater, reductions in BP, with meta-analyses reporting mean reductions of between 10 and 13 mmHg systolic, and 6 and 8 mmHg diastolic. Isometric exercise training protocols typically consist of four sets of 2-min handgrip or leg contractions sustained at 20-50 % of maximal voluntary contraction, with each set separated by a rest period of 1-4 min. Training is usually completed three to five times per week for 4-10 weeks. Although the mechanisms responsible for these adaptations remain to be fully clarified, improvements in conduit and resistance vessel endothelium-dependent dilation, oxidative stress, and autonomic regulation of heart rate and BP have been reported. The clinical significance of isometric exercise training, as a time-efficient and effective training modality to reduce BP, warrants further study. This evidence-based review aims to summarize the current state of knowledge regarding the effects of isometric exercise training on resting BP.
