This is primarily due to the cologne in connective tissues becoming denser as we age, but also reduction selectivity within the cartilage, the ligaments and the tendons. There’s also a clear link between the levels of physical activities and flexibility. Summing up simple as regular walking, for instance, has been proven to have a positive influence of mobility within the hips and spine. And believe it or not the time of day can actually affect your level of flexibility due to Circadian Rhythms, affecting body temperature and hormonal activity.
Now improvements in your flexibility are achieved through was referred to Developmental Stretch, a static stretch that’s carefully applied and aims to lengthen the elastic muscle beyond its original length. The result is that each muscle’s cell that normally contains protein filaments, that are overlapped, begins to elongate. In addition to this, the collagen fibres within the connective tissue, that surrounds the muscle, sort to align themselves with this direction of tension. This later point explains why rehabilitation for muscle injury always in bone stretching has scat issue that forms, is made primarily of collagen fibres.
The American College of Sports Medicine recommends including flexibility training 3 times per week. Now later lecture we have, we’ll focus entirely on the topic of stretching together with reviewing the various techniques and the body’s responses to them.
The final health related fitness component is Body Composition. This element is more important measure than weight to lowing that allows us to access the percentage of our body weight that is true be to the fat. Now this is a valuable statistics that since the medical fertility universally agrees that excess of body fat can lead to increased risk of:
- Cardiovascular Disease
- Joint Problems
- Respiratory Issues
- High Blood Pressure
- Differences in the body composition explain why two women or two men may be having similar weight but totally different shapes. The tricky part is to get you head around is that lean body weight, I’m talking about muscles & bones are more dense than fat. So you could be looking someone who is in great shape but actually weighs way more than the cuddly friend standing next to them.
This principle also explains why it’s possible that you can make yourself to an exercise rate and burning fat and you’re looking great. But why you’re not losing any weight? In fact, you might gain weight. But if it’s not body fat, if it’s instead muscle, if its healthy weight, then that can’t be a bad thing. Starting to thinking that why many of us have become obsessed with our weight doesn’t it? So such a complex person, that later in the series, we’ll take time to look at this issue specifically.
So what are the recommendations for percentage of your body fat, the National Institute of Health target guidelines are:
- 20%-21% for women (>30% is considered as obese)
