Critical Thinking and Reading Science . Logical Fallacies . Hasty Generalization. This is a conclusion based on insufficient or biased evidence. In other words, you are rushing to a conclusion before you have all the relevant facts. . Shifting the burden of truth . Argument from ignorance .
Assuming a claim is true because it has not been proven false or cannot be proven false.
“Once seated you need to keep at least 20 percent tension in your abs to maintain a rigid spine” – kellystarret
During standing and walking the trunk muscles are minimally activated . In standing the deep erector spinal, psoas and quadratuslumborum are virtually silent! In some subjects there is no detectable EMG activity in these muscles. During walking rectus abdominis has a average activity of 2% maximal voluntary contraction (MVC) and external oblique 5% MVC . During standing “active” stabilisation is achieved by very low levels of co-contraction estimated at less than 1% MVC rising up to 3% MVC when a 32 Kg weight is added to the torso. – science
(1) The fall of the postural-structural-biomechanical model in manual and physical therapies: exemplified by lower back pain
Studies in humans, for the most part, fail to replicate this; this may be related to less actual activity of de novo lipogenesis in humans and a much higher level in rats. Some isolated studies do note weight loss, but it appears to be quite variable and unreliable. Many studies also do report subjective appetite decrease, but tend to record dropout rates (how often people leave the study due to being unable to maintain the diet protocol) rather than food intake; even then the benefits are still unreliable and sometimes not present.
(2) Total body weight did not change at delta 48 or delta 80. Mean (+/- SE) lean weight in kg increased from 42.9 +/- 1.2 at baseline to 44.8 +/- 1.2 at delta 80 (P = 0.002). We have reported previously that at delta 48 the subjects had evidence of mild thyroidal impairment, which consisted of decreased T3 and rT3, and an exaggerated TSH response to TRH. With more prolonged training (delta 48 to delta 80) there were significant increases in T4, rT3, and unstimulated TSH, while the ratios of T4/rT3 and T3/rT3 and the TSH response to TRH decreased significantly. Some of the thyroidal changes that occurred between delta 48 and delta 80 are similar to those seen in other stressful non-thyroidal conditions.
(3) 17 freshmen (group 1) before and after six months of competition rowing; controls (group II) were 19 senior rowers, already participating in a training program for more than 2 years.
(4) The estimated net energy deficit induced by training was 244 MJ and was associated with a 5-kg body weight loss that was almost entirely explained by body fat loss. Resting metabolic rate (RMR) was significantly decreased by 8% after training despite the preservation of fat-free mass (FFM)
