However, some studies do show that even just six sessions of interval training can lead to improvements in maximal oxygen uptake (V02 max), which is a measure of overall fitness. In addition, these sessions improve how efficiently our body is able to fuel itself using the sugar stored in our cells during exercise. For strength training, a number of different gains in muscle force may be shown in as little as two weeks, however changes in muscle size won\u2019t be seen until around 8-12 weeks.<\/p>\n

<\/a><\/strong><\/h2>\nBecoming Unfit Takes Place In Stages<\/strong><\/h2>\nDifferent systems in our body lose fitness<\/a> at different rates, but generally speaking, it takes about between three and four weeks to notice a considerable change in one’s fitness levels.<\/p>\nLet’s take recreational exerciser, Jane, for instance. Jane is someone who logs about three days a week of physical activity and still has sufficient levels energy to run around after her terrible two-year old. Jane developed an illness and was down and out for a month before she felt reasonable enough to resume her exercise programme.<\/p>\n
The first system that lost fitness was Jane’s cardiovascular system. With no physical activity over the last month, Jane’s ability to consume \u2013 as well as utilise oxygen – had considerably diminished. In fact, after just 10 to 14 days of sedentary behaviour, a person’s aerobic system begins to decline.<\/p>\n
The muscular system<\/a> is also affected by not training, albeit less dramatically as opposed to the cardiovascular system. We lose muscular strength and endurance after about four weeks of inactivity. During the first few weeks, the effects are hardly noticeable, but after the four-week mark, muscle fibres start to shrink. Muscles lose their “bulky” feeling, becoming softer, smaller as well as weaker. But there is a bit to be said for muscle memory, and typically upon resumption of training, it is fairly easy to regain muscular performance.<\/p>\nContact Trifocus Fitness Academy<\/strong><\/a><\/h2>\nIf you are keen to discover more about fitness \u2013 and teaching others how to become fitter \u2013 then you need to do our Personal Training Diploma.
