肌肉與運動

Exercise that is relatively low intensity but long duration (popularly called "aerobic exercise"), such as running or swimming, produces increases in the number of mitochondria in the fibers that are recruited in this type of activity. In addition, the number of capillaries around these fibers also increases. All these changes lead to an increase in the capacity for endurance activity with a minimum of fatigue. (Surprisingly, fiber diameter decreases slightly, and thus there is a small decrease in the maximal strength of muscles as a result of endurance training.) As we will see in later chapters, endurance exercise produces changes not only skeletal muscles but also in the respiratory and circulatory systems, changes that improve the delivery of oxygen and fuel molecules to the muscle.

In contrast, short-duration, high-intensity exercise (popularly called "strength training"), such as weight lifting, affects primarily the fast-glycolytic fibers, which are recruited during strong contractions. These fibers undergo an increase in fiber diameter (hypertrophy) due to increased synthesis of actin and myosin filaments, which form more myofibrils. In addition, glycolytic activity is increased by increasing the synthesis of glycolytic enzymes. The result of such high-intensity exercise is an increase in the strength of the muscle and bulging muscles of a conditioned weight lifter. Such muscles, although very powerful, have little capacity for endurance, and they fatigue rapidly.

Fast-glycolytic fibers have relatively fast contractions and primarily use anaerobic glycolysis.

bulging: swollen with contents

Enhancing cardiovascular fitness can lead to substantial health benefits. High-intensity interval training (HIT) is an efficient way to develop cardiovascular fitness, yet comparisons between this type of training and traditional endurance training are equivocal.

equivocal: uncertain as an indication or sign

Endurance training and HIT both elicit large improvements in the VO2max of healthy, young to middle-aged adults, with the gains in VO2max being greater following HIT when compared with endurance training.

Growth in cell numbers is limited to the prenatal and immediately postnatal period, with the animals and man being born with or soon reaching their full complement of muscle cells.

管教問題

上次外甥女到公公婆婆屋企食飯,發生一段小插曲。當我返家時,大家已經吃完晚餐。公公婆婆前幾日睇中醫,餅乾罐有兩三筒山楂餅。我眼見地上有山楂餅包裝紙碎,便道︰「地上有紙屑,誰弄出來的?」正在吃山楂餅的外甥女沒有理會我,隔一會姐夫拾起紙屑放在臺面上,而不是直接掉進垃圾桶。

有次聽阿媽講︰「阿女、女婿和孫女番來吃飯,成日煮沙巴龍躉(按︰中價魚)都有點悶,有一次買了一尾游水黃花。阿女以為魚脊附近沒有魚骨,便夾給孫女吃。孫女食到有幼骨即吐,阿女、女婿不覺得有什麼問題。」如果我在場,應該會說一兩句。不理平貴,浪費食物,始終不對。

外甥女快六歲了,一直由印傭和任職保險的姐夫照顧,家姐在家工作那段期間才多了參與。我覺得,自理能力、禮貌有時比起上哪間名校、鋼琴彈奏得多動聽更加重要。
