“…Although associations among the fitness components in the present study were weaker than in previous studies on people with ScI, they do appear to be stronger than what has been found in able-bodied groups (16,18,35). In these groups, no or weaker associations were apparent among upper-body and lower-body fitness components of able-bodied people (16,18,35).…”

“…In these groups, no or weaker associations were apparent among upper-body and lower-body fitness components of able-bodied people (16,18,35). A possible explanation for this difference is that, on a group level, wheelchair users with ScI are more homogenous in their development of upper-body aerobic, lactic and alactic metabolism compared with upper-body and lower-body metabolism of able-bodied people (36).…”

“…If the outcomes of different components are strongly associated, it implies that separate tests for each component are not necessary, since an outcome of 1 component could be used to predict another, which may reduce measurement burden (16)(17)(18). Furthermore, strong associations may also imply that different exercise forms can improve various…”

Objectives: To describe wheelchair-specific anaerobic work capacity, isometric strength and peak aerobic work capacity of physically inactive people with long-term spinal cord injury using outcomes of tests that are feasible for use in rehabilitation centres, and to determine associations among these fitness components. Design: Cross-sectional study. Participants: Manual wheelchair users with spinal cord injury for at least 10 years, who were inactive based on a norm score of a physical activity questionnaire (n = 29; 22 men; 20 with paraplegia; median age 53 years). Methods: Participants performed 3 exercise tests in their own wheelchair to determine: highest 5-s power output over 15-m overground sprinting (P5-15m); highest 3-s isometric push-force (Fiso); and peak power output (POpeak) and peak oxygen uptake (VO 2 peak) over a peak test. Conclusion: All fitness components measured in this sample were at relatively low levels, implying a specific need for interventions to improve wheelchair-specific fitness. The weak-to-moderate associations among components imply that separate tests should be used when monitoring wheelchair-specific fitness in rehabilitation centres.

“…Fitness and muscle strength have previously been shown to have no or minor association (r=0.05-0.2). 19,20 In contrast, we found a moderate association (r=0.25), although it should be noted that our analysis is based on correlating stanines and not raw data. Although muscle strength seems to be associated with measures of combined cardiovascular disease risk independently of aerobic fitness, 11 only high muscle strength showed a protective effect, although a relatively weak one (relative risk reduction, 12%).…”

Stroke afflicts ≈1 in 6 people in their lifetime, 1 causing 6.2 million deaths worldwide.2 To improve stroke prevention, knowledge of key risk factors, especially those that are modifiable such as physical activity, is essential. In middle-aged men 3 and women, 4 it has been shown that higher levels of physical activity are associated with reduced risk of future ischemic stroke (IS). Specifically, in 2 meta-analyses on 16 original studies of middle-aged men and women undertaking more intensive versus lower levels of physical activity, the overall risk reduction was 19% to 27%. 5,6 However, in these and most other such studies, physical activity is assessed by self-report in questionnaires and interviews in large numbers of subjects, yet it has been shown that self-report leaves the true degree of physical activity vulnerable to bias. 7Aerobic or cardiovascular fitness (henceforth fitness), however, can be measured objectively. Although measurement requires relatively time-consuming ergometric tests, and so has generated fewer observations and studies, it has been shown to be a more accurate predictor of cardiovascular risk Background and Purpose-Low cardiovascular fitness (fitness) in mid-and late life is a risk factor for stroke. However, the respective effects on long-term stroke risk of fitness and muscle strength in early adulthood are unknown. Therefore, we analyzed these in a large cohort of young men. There were stronger associations for fatal stroke. All 3 stroke types displayed similar associations. Associations between fitness and stroke remained when adjusted for muscle strength, whereas associations between muscle strength and stroke weakened/disappeared when adjusted for fitness. Conclusions-At the age of 18 years, low fitness and to a lesser degree low muscle strength were independently associated with an increased future stroke risk.

“…A similar pattern of results has been reported in a study of cyclists with cerebral palsy, which found that isokinetic muscle strength in the best leg was more strongly correlated with peak aerobic capacity than strength in the worst leg (de Groot et al 2012). This pattern may be partly explained by the fact that athletes whose best leg is relatively unimpaired are also likely to have a relatively unimpaired worst leg.…”
