The phrase "accurate physical activity" is correct and usable in written English.
It can be used when discussing the precision or correctness of physical activities, such as exercise or movement.
Example: "To achieve optimal health, it is essential to engage in accurate physical activity that aligns with your fitness goals."
Alternatives: "precise physical exercise" or "correct physical movement".
Observational and biomechanical measurements would provide more accurate assessment of physical activity.
Observation and biomechanical measurements might be more accurate in measuring physical activity.
The main strength of this study was yearly measurements of the outcome, which enabled us to get accurate estimates of physical activity during the actual retirement transition.
Therefore, this accurate measurement of physical activity in daily life in this population is important and can add valuable information regarding this subject.
The accurate measurement of physical activity (PA) and sedentary behaviour is essential to evaluate their health impact in terms of amount and intensity [ 1, 2].
A more comprehensive examination of various knee structures and the implementation of objective and accurate assessments of physical activity may also enhance our understanding of the mechanism by which physical activity affects the knee joint.
Although the difficulties in accurate assessment of physical activity levels in epidemiological studies are well known (IARC Working Group, 2002), there is no evidence that reporting varies by level of anxiety.
While the accurate assessment of physical activity may be important for the quality of the research [ 5], using accelerometers is more expensive than using other commonly used methods such as questionnaires or pedometers [ 10] and it is unrealistic to expect that devices could be issued to every participant simultaneously when the sample size is large.
Studies performed in patients with CF have validated the use of the SenseWear Armband and have shown that the hypersalinity of sweat does not affect the accuracy of EE estimation, and have demonstrated that the device provides an accurate estimate of physical activity in the free-living environment [ 23, 24].
To elucidate these mechanisms will likely require the application of accurate and precise measures of physical activity to appropriately designed studies.
