What is the recommended intake of carbohydrate during intermittent, high-intensity sports?

1 answer:

6 0

I think the recommended intake of carbohydrates during intermittent, high-intensity sports is 7-12 g/kg Body weight daily. For very high intensity training (4 hrs) is 10-12 g/ kg BW daily, while for moderate intensity training (about 1 hour daily) is 5-7 g/ kg BW daily and for very light training is about 3-5 g/ kg BW daily.

Please also describe how actin-binding sites are made available for cross-bridging with myosin heads during contraction.

Answer: The calcium ion binds to troponin, and this slides the tropomyosin rods away from the binding sites.

Explanation:

Contraction and relaxation of muscle cells brings about movements of the body. The contractile myofilament called sarcomeres are bounded at each end by a dense stripe called the Z - line, to which the myosin fibres are attached, and lying in the middle of the sarcomere are the actin filaments, overlapping with the myosin.

When action potential spreads from the nerve along the sarcolemma (muscle cell membrane), it penetrates deep into the muscle cell through the sarcoplasm (cytoplasm of muscle cell), and releases CALCIUM from the intracellular stores.CALCIUM triggers the binding of myosin to the actin filament next to it forming CROSS BRIDGES.

For this to occur, ACTIN BINDING SITE has to be made available. TROPOMYOSIN is a protein that winds around the chains of the actin filament and covers the myosin-binding sites to prevent actin from binding to myosin. The first step in the process of contraction is for calcium ions to bind to troponin so that tropomyosin can slide away from the binding sites on the actin strands.
