概括
身体活动会根据炼强度和个人的身体状况不同,对唾液成分和味觉有不同的影响. 适度的运动可以增强活动人士的甜味,而高强度的运动可以增强久坐不动的人的甜味.
科学领域:
- 运动生理学 运动生理学
- 口服生物化学口服生物化学
- 感官科学是一种感官科学.
背景情况:
- 运动的生理效应已经得到了充分的证据,但它对唾液,食欲和口腔生物化学,包括味觉,的影响尚未完全理解.
- 了解运动引起的唾液变化对于探索其与味觉的相互作用至关重要.
研究的目的:
- 研究高强度间歇训练 (HIIT) 和中等强度持续训练 (MICT) 对唾液组成和感知味道强度 (甜味和苦味) 的影响.
- 为了比较活跃和久坐的人之间的这些影响.
主要方法:
- 在MICT和HIIT课程之前和之后,评估了36名参与者 (18名活跃,18名静坐) 的非刺激的唾液样本和口味强度等级.
- 分析了唾液分泌率,总蛋白质度和蛋白质组概况 (SDS-PAGE,2-DE).
- 使用味道带评估甜 (糖) 和苦 () 的味道强度.
主要成果:
- MICT增加了活跃个体的甜味强度;HIIT增加了久坐的人. 苦味的味道感知保持不变.
- 运动后唾液分泌率下降,而蛋白质度增加.
- 运动改变了基于身体健康水平和运动类型的唾液蛋白质概况. 在活跃个体中,白蛋白和-α2-糖蛋白+碳酸 VI降低,后者与味道强度的变化有关. 在活跃个体中,氨酶在HIIT后增加.
结论:
- 身体活动对唾液和味觉的影响取决于运动强度和个人的生活方式 (活跃或久坐).
- 这些发现表明,在涉及体育活动的营养策略中,应考虑运动类型和参与者的健康状况.

Salivary Glands and Saliva
2.2K
The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...

The Physiology of Taste
7.1K
The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the...

Taste Buds and Receptors
4.5K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Gustation
51.8K
Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.

The Tongue and Taste Buds
40.5K
The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.
