Possible Interaction: Dietary Fiber and Calcium Supplement

“The maximum level of force production (per unit cross‐sectional area) in fast twitch fibres in Old subjects was lower than in Young subjects, and the fibres were also less sensitive to activation by calcium.”

“The effect of other nutriments is less clear, although an excessive consumption of sodium, caffeine, or fibres exerts negative effects on calcium balance.”

“This structural disturbance allows Ca++ to enter the fibre down its electrochemical gradient, precipitating the Ca++overload phase.”

“The fibre area per CA decreased by about 10%.”

“This binding by the non-cellulosic fraction of fibre will reduce the availability of calcium for small-intestinal absorption, but the colonic microbial digestion of uronic acids will liberate the calcium.”

“ Fecal calcium content correlated significantly with fecal fiber in two subjects, and fecal fiber and zinc in one.”

“The presence of soluble fibres increased viscosity by ca.”

“For the same reason, one could still suspect that the experimental conditions may have hindered the potency of mouse fibres to produce CICR because of, for instance, a lost physiological RyR1-sensitizing component necessary in mouse but not in frog.”

“We conclude that calcium uptake is a limiting factor in the ability to sustain the trains of high frequency, non-fused synchronous contractions of which these fibres are capable.”

“The time resolution was about 5 s.The initial rise in ATPase activity was delayed when a fibre was activated by Ca , and ATPase activity reached its plateau at the same time as fibre tension.”
