年紀和肌肉發展的關係
年紀大等於較小訓練效果⁉️

🤔🤔🤔
頂級運動員退休的原因是他們太老嗎？
頂級運動員年齡平均值為20多歲［10］。而奧林匹克舉重選手的年齡平均值為26歲 。［9］但我們細心想想，頂級運動員退休的原因通常都是傷患、有關藥物使用的風險(drug-related health risks)、較佳的工作機會等等...

當我們更加深入探討有關力量和肌肥大的時候，我們會發現健力運動員都會在35歲(平均值)時達到最佳的狀態[11]。而有關健美運動員的研究不多，但當我們細心觀察那些傑出的健美選手時，會發現他們達到職業巔峰的時期通常都是在30-40多歲。
例子：Ronnie Coleman, Phil Heath, Dorian Yates, Arnold Schwarzenegger, Jay Cutler...

研究背景
研究對象為18至39歲的男性和女性，使用磁力共振掃描(MRI)檢測肱二頭肌橫截面面積和測試肘屈肌群的一下最大力量(1RM)，然後進行為期12星期的單邊手臂(非主用手)重量訓練。
訓練期結束後，再次使用磁力共振掃描(MRI)檢測肱二頭肌橫截面面積和測試肘屈肌群的一下最大力量。對比訓練前和訓練後的結果，最後得出當中的改變。

圖2A, 對象的肱二頭肌經歷12星期的重量訓練後，都有所增長。而各年齡層的肌肉增長沒有實際分別。在成年初期，年齡不會影響肌肉對重量訓練的反應。

圖2B,
年紀和二頭彎舉一下最大力量(1RM)有着負相聯的關係。

標題: Epidemiology of Sarcopenia [1]
研究背景及設計:
在明尼蘇達州的人群研究 (population-based study in Rochester, Minnesota)
年齡層抽樣方式提取數據 (Age stratified sample of men and women from the community)

😨😨😨
大眾而言，肌少症在大約20歲開始。不論性別，隨着人們年紀的增長，肌肉量都會穩定地下降。
既然肌少症在20歲開始...但是為什麼健力和健美運動員會在30～40多歲時達到運動表現的巔峰？

流失肌肉量·真正的成因⁉️
研究要點✅

1️⃣引致肌少症的主要成因，包括缺乏運動的生活方式和營養不良。[7]

2️⃣年紀令肌肉機能弱化，不使用(遺棄 disuse)肌肉會加劇這個問題 [8]

3️⃣要點:長期不使用肌肉(chronic disuse)，是肌肉量流失和力量下降最主要的成因，並非老化(aging) [6]

4️⃣年紀不影響肌肉對力量訓練的反應 [4]

5️⃣年輕和老年的女性有着差不多的肌肥大及力量增長 [5]

6️⃣年輕和老年的個體有著差不多的肌肥大增長 [3]

BMW M135i vs Mercedes AMG A35 vs Mini Clubman JCW

For years now, #BMW has been insisting that the vast majority of 1-Series customers are not worried about whether the engine drives the front or rear wheels. It would therefore be a shame for the same customers that the new 1-Series switched to front-wheel drive, unless in that case as #M135i ... which is now systematically linked to the xDrive four-wheel drive. What about the sporty temperament without the typical driving behavior of a rear-wheel driver? And what driving sensations can we expect from a chassis that is ultimately designed for a front wheel tractor? Does the 135i actually deserve its M badge? These are all questions we try to answer based on a comparative test of BMW's youngest sportsman with two of his biggest competitors: the #Mercedes-#AMG A 35 4Matic and the #Mini #Clubman JCW All4.

The changeover to the BMW front-wheel-drive architecture is reflected in the new proportions and flowing, elongated lines of the all-new BMW 1-Series. The shorter bonnet melts into the windscreen, while the long roofline drops away slightly towards the rear. A wide tail with an athletic shoulderline above the rear wheel arches emphasises the car's powerful, sporty presence when viewed from behind. At the same time, the compact body offers significantly more space within a footprint almost identical to the predecessor model's and so makes the car even more versatile in everyday use. At 4,319 millimetres, the new BMW 1-Series is five millimetres shorter than its predecessor. In terms of width (now 1,799 millimetres), this third-generation model has grown by 34 millimetres while its height (1,434 mm) has increased by 13 millimetres. At 2,670 millimetres, the wheelbase is 20 millimetres shorter than that of the predecessor model.

Of the various engines available for the new BMW 1-Series, it is the newly developed four-cylinder unit under the bonnet of the BMW M135i xDrive that really steals the show. It is the BMW Group's most powerful four-cylinder engine, extracting 225 kW (306 hp) from its 2.0-litre displacement between 5,000 and 6,250 rpm with the help of BMW TwinPower Turbo technology. Its peak torque of 450 Nm (332 lb-ft) comes on stream at 1,750 rpm and stays there up to 4,500 rpm. The flagship model races to 100 km/h (62 mph) from rest in just 4.8 seconds (4.7 seconds with M Performance package, available from 11/2019), while top speed is limited to 250 km/h (155 mph). Despite such breathtaking performance figures, the BMW M135i xDrive makes do with 7.1 - 6.8 litres of fuel per 100 kilometres (39.8 - 41.5 mpg imp) on the combined cycle and emits just 162 - 155 grams of CO2 per kilometre.

Emotional, agile and digital: with the A35 4MATIC Mercedes-AMG is presenting a completely new entry-level model to the world of driving performance. It is based on the new Mercedes compact vehicle platform and is powered by a new 2.0-litre four-cylinder turbo engine with output of 225 kW (306 hp). Body shell, suspension, all-wheel drive, transmission, drive programs, fine tuning - every detail has been designed for maximum driving dynamics without compromising on everyday comfort. The performance at sports car level (acceleration 0-100 km/h in 4.7 seconds) and the specific design also strengthen its identity as a member of the performance family. A true AMG for the Hot Hatch stage!

The AMG SPEEDSHIFT DCT 7G dual-clutch transmission also contributes to the agile and dynamic character of the new A35 4MATIC. The gear ratios have been configured so that the driver experiences very spontaneous acceleration in all speed ranges, combined with fast shifting and optimum connections when shifting up. The standard RACE-START function allows maximum acceleration from stationary and is a highly emotional experience. The functions of the AMG SPEEDSHIFT DCT 7G transmission are rounded off with a temporary M mode activated by operating the steering wheel shift paddles in any driving mode, and with the manual transmission mode "M" for manual gear shifting with the shift paddles.

As the power source for extreme driving fun, the comprehensively redesigned 4-cylinder engine has been consistently oriented towards maximum output. It is based on the 2.0 litre drive from the MINI Cooper S Clubman and MINI Cooper S Countryman but has now undergone model-specific modifications to the crankshaft drive and also benefits from the latest generation of MINI TwinPower Turbo technology. These modifications are based on the John Cooper Works' racing know-how and comprise a reinforced crankshaft, a main bearing with an extended cross-section, specific pistons, connecting rods, and a new vibration damper with optimised cooling.

The high-performance drive of the new MINI John Cooper Works Clubman and the new MINI John Cooper Works Countryman generates a maximum torque of 450 Nm in the broad engine speed range between 1 750 and 4 500 rpm, which is around 28 percent higher than that of the previous engine. The maximum output of the new 4-cylinder engine has been increased by approximately 32 percent. The new top level of 225 kW/306 hp is reached between 5 000 and 6 250 rpm. The resulting pulling power enables the new engine of the MINI John Cooper Works Clubman to produce an acceleration performance of 0 to 100 km/h in 4.9 seconds, while the figure for the new MINI John Cooper Works Countryman is 5.1 seconds, ensuring an impressive level of elasticity during spontaneous speed bursts. For the first time with MINI vehicles, the maximum speed of the new top sports performer is now electronically limited to 250 km/h.
