1. According to studies, consuming up to 2-3 coffee in front of the gym can help us to burn more calories after physical activity!
2. Coffee consumption in front of the gym helps in the best circulation of blood and in turn the best oxygenation of each cell of our body.
3. 1 cup of 2 cups helps us to have less pain and muscle contraction.
4. Less carbohydrate coffee, like a little milk or sugar, helps us get more energy to carry out physical activity!
Smooth muscle cells contract in response to neuronal or hormonal stimulation, either of which results in an increase in intracellular calcium as calcium enters through membrane channels or is released from intracellular storage sites.
The elevated level of calcium in the cell cytoplasm results in force generation.
The rise in the level of intracellular calcium, however, initiates contraction through a mechanism that differs substantially from that in striated muscle.
In striated muscle, myosin cross bridges are prevented from attaching to actin by the presence of the troponin-tropomyosin system molecules on the actin filament (see above the Striated muscle).
In smooth muscle, although tropomyosin is present, troponin is not, which means that an entirely different regulatory scheme operates in smooth muscle.
Regulation of the contractile system in smooth muscle is linked to the myosin filament; regulation in striated muscle is linked to the actin filament.
In order for the smooth muscle myosin cross bridge to interact cyclically with actin, a small protein on the myosin molecule called the light chain must be phosphorylated (receive a phosphate group).
This phosphorylation is the result of a series of interdependent biochemical reactions that are initiated by the rise in intracellular calcium.
For the cell to relax, the concentration of intracellular calcium falls, thus inactivating these biochemical processes associated with light chain phosphorylation.
The phosphate molecule that was added in the previous steps, however, still must be removed from the light chain so that attachment of the cross bridge to actin is prevented.
Phosphatases are enzymes in the muscle cell that cleave the phosphate group from the myosin light chain.
