まとめ
運動前に米を食べると 初めは血糖値が上がります 運動中に血糖値が低下し,呼吸器交換比率が上昇します.
科学分野:
- 栄養生理学
- 運動 代謝
- 内分泌学
背景:
- マクロ栄養素の摂取順序は食後の血糖値に影響する.
- 食事のマクロ栄養素配列が運動による血糖値と代謝反応に与える影響は十分に理解されていません.
研究 の 目的:
- タンパク質と野菜の前後に米を摂取すると,運動中の血糖と呼吸器の交換にどのような影響があるかを調べる.
- 食事のマクロ栄養素の順序が,運動の前と運動中の代謝反応に与える影響を決定する.
主な方法:
- 18人の健康な成人を対象としたランダム化クロスオーバー試験です.
- 参加者は最初または最後に米を食べ,その後60分間の休憩と30分間のランニングを行いました.
- 休息と運動期間中,血糖と呼吸器交換比率をモニタリングした.
主要な成果:
- 米を最初に摂取した状態は,食後30分後に,米を最後に摂取した状態と比較して,血糖値が有意に高かった.
- 運動前と運動後の血糖値の減少は,米を第一に摂取したグループで観察されました.
- 米を最初に食べるパターンは 休息時の呼吸器交換比率が高くなり 運動中に持続した.
結論:
- タンパク質と野菜より先に米を摂取すると,最初は血糖が高くなり,運動後にはより顕著な血糖低下が起こります.
- 米を最初に食べる戦略は,休息と運動中の呼吸交換比率の増加によって示される基板の利用に影響を与えます.
- 食事のマクロ栄養素配列は,運動に対する糖質と代謝の反応を調節する役割を果たします.

2.4K
Carbohydrates consumed through foods are converted into glucose, a crucial energy source for the body. In the prandial state, high blood glucose levels stimulate the secretion of insulin from the pancreas. Insulin inhibits hepatic glucose production and stimulates glucose uptake and metabolism by muscle and adipose tissue. The excess glucose is converted into glycogen and stored in the liver and muscles.

Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

01:18Metabolic States of the Body: The Postabsorptive State
534
The postabsorptive state usually starts about four hours after a meal and lasts until the next meal is eaten. During this time, the digestive system stops absorbing nutrients, and the body uses stored energy reserves to maintain stable blood glucose levels.
Initially, glycogen stored in the liver is broken down to release glucose into the bloodstream, while glycogen in the muscles is broken down to supply glucose for energy directly within the muscle cells. As glycogen stores diminish,...

01:25Metabolic States of the Body: The Absorptive State
789
During the absorptive state, which lasts approximately four hours after a meal, the body absorbs nutrients from the gastrointestinal tract. The carbohydrates, proteins, and lipids we consume are broken down into monosaccharides, amino acids, and free fatty acids for absorption. While carbohydrates and proteins are absorbed as-is, lipids are absorbed in their broken-down forms and then re-esterified into triglycerides within enterocytes before being packaged into chylomicrons. These absorbed...

01:16Hormones Regulating Blood Glucose
4.0K
Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...

01:24Metabolic States of the Body: Fasting and Starvation
1.7K
During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...
