The Gram matrix is symmetric in the case the inner product is real-valued; it is Hermitian in the general, complex case by definition of an inner product. The Gram matrix is positive semidefinite, and every positive semidefinite matrix is the Gramian matrix for some set of vectors. The fact that the Gramian matrix is positive-semidefinite can ...

The exercise paradox, [1] also known as the workout paradox, [2] refers to the finding that physical activity, while essential for maintaining overall health, does not necessarily lead to significant weight loss or increased calorie expenditure. [3]
The energetic cost of running can be quantified through the measurement of oxygen consumption (VO2) during running at a given submaximal speed. During aerobic activities (like submaximal running), VO2 provides an indirect estimate of energy expenditure. [8]
