まとめ
乳酸の蓄積が高く,午後と夕方にはパフォーマンスのピークがあります. 夜型に近い個体は,その日の後半に乳酸クリアランスを改善し,トレーニング戦略に影響を与えます.
科学分野:
- 運動 生理学
- クロノバイオロジー
- スポーツ科学
背景:
- シルカディアンリズムは神経筋機能を含む生理機能に影響します.
- アナーロビック容量と代謝反応の1日間の変動は完全に理解されていません.
- クロノタイプは,運動選手におけるこれらの昼間の変動を調節する可能性があります.
研究 の 目的:
- アナーロビック性能と血中乳酸動態に対する昼間の影響を調査する.
- 中間型 (IT) と夕方型 (CET) に近いクロノタイプの潜在的な違いを調べる.
- サーカディアンリズムに基づいたトレーニングと回復戦略の情報提供
主な方法:
- 訓練を受けた20人の男性選手 (ITとCETクロノタイプ) は,垂直ジャンプとスプリント能力のテストを繰り返しました.
- テストは午前7時~8時,午後13時~14時,夕方18時~19時に行われました.
- 血液中乳酸のレベルは,試験開始時,試験終了後3分,および試験終了後33分で測定された.
主要な成果:
- アナエロビック性能 (垂直ジャンプのピークと平均パワー,繰り返しスプリントの能力) は,午前と比較して午後と夕方には著しく高かった.
- 乳酸の蓄積は,すべてのアスリートで午後と夕方 (3分後) より大きい.
- 夜間型 (CET) の運動選手は,夜間型 (IT) の運動選手とは異なり,乳酸クリアランスが優れていた.
結論:
- 訓練されたアスリートの無酸素性能と乳酸代謝に大きく影響する.
- 神経筋機能と代謝反応に対する日々の影響は明らかである.
- クロノタイプは乳酸クリアランスに作用し,個別化されたトレーニングと回復スケジュールを提案します.

Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

01:24Muscle Recovery and Fatigue
2.5K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

4.1K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

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...
