Sex Without Arms Or Legs



The aim of the present study was to compare arm and leg anaerobic peak and mean power after normalisation for body mass (W/kg) and fat-free mass (W/kg FFM) of 12 female and 10 male wrestlers, members of the Polish Olympic team. Power outputs were assessed by 30 seconds leg cycling and 30 seconds arm cranking. It was determined that males had higher peak power (11.4 W/kg and 13.2 W/kg FFM for legs, 9.6 W/kg and 11.2 W/kg FFM for arms) as well as mean power (8.7 W/kg and 9.6 W/kg FFM for legs, 6.9 W/kg and 7.9 W/kg FFM for arms) than females (peak power 8.6 W/kg and 11.3 W/kg FFM for legs, and 5.9 W/kg, 7.8 W/kg FFM for arms, mean power 6.8 W/kg, 9.0 W/kg FFM for legs and 5.9 W/kg, 7.8 W/kg FFM for arms). Post-exercise maximal blood lactate concentration after 30 seconds leg cycling and 30 seconds arm cranking was also higher in male wrestlers (11.9 and 11.8 mmol/l, respectively) than in female wrestlers (10.4 and 9.1 mmol/l, respectively). However the ratios of lactate concentration to mean power expressed in W/kg FFM for males and females in leg cycling (1.18 and 1.17, respectively) and in arm cranking (1.48 and 1.50, respectively) were similar. These findings suggest that the amount of energy derived from glycolysis is not sex-dependent. Additionally it seems that the higher ratios for arms when compared to legs reflect closer relation of arm muscle energy metabolism to carbohydrate utilisation.

Scott was born with Tretra-amelia syndrome, resulting in her having no arms or legs, and was celebrated in the local and regional press in 2018 after becoming the first Kentuckian to receive a robotic arm.


By this age, your baby probably will be sitting without support. Although she may topple from time to time, she'll usually catch herself with her arms. As the muscles in her trunk strengthen, she'll also start leaning over to reach objects.


When lying on a flat surface, your baby is now in constant motion. When on her stomach, she'll arch her neck to look around, and when on her back, she'll grab her feet (or anything else nearby) and pull them to her mouth. She won't be content to stay on her back. She can turn over at will now and flip without a moment's notice. This can be dangerous during diaper changes, so you may want to retire her changing table, using instead the floor or bed, from which she's less likely to fall. Never leave her alone for an instant at any time.


ll this activity strengthens muscles for crawling, a skill usually mastered between seven and ten months. For a while she may rock on her hands and knees. Since her arm muscles are stronger than her legs, she may even push herself backward. But with time and practice she'll discover she can propel herself forward across the room toward the target of her choice.


Newborn reflexes. In addition to rooting, your baby may show other reflex movements these first weeks. To see the step reflex in action, hold your baby securely under his arms (support his head, too!) as his feet touch a flat surface; he may put one foot in front of the other in a sort of "walking" motion. This reflex disappears after the first couple months, and most babies don't take their first "real" steps until about a year old.


Hand to mouth. During these weeks, your baby may begin to wave his arms around more when excited. Increasingly, his hands will catch his attention. He may spend a lot of time trying to move them in front of him where he can see them. After many tries, he may be able to move them to his mouth. His finger motion is still limited, though, so his hands will likely still be clenched in tight little fists. Sucking on them may become a way for him to soothe himself.


Straightening out. You might notice your baby's whole body now looks more relaxed. His hands will no longer be balled up in fists all the time. In fact, he may entertain himself by carefully opening and shutting them. He'll also enjoy more actively kicking his legs, which are straightening out from their pulled-up newborn position.


Let's bounce. When held up and supported in a "standing" position on a surface such as your lap, your baby may discover the joy of bouncing. This is a fun way to play together as your baby begins to hold some of his weight in his legs. It's best to avoid leaving babies in bouncer seats or harnesses. These can actually slow your baby's movement progress because they don't let her practice using her muscles as much.


To learn more about what that's like, VICE recently spoke to Ali Lapper, an artist born with no arms and shortened legs, and her partner Si Clift about the realities of sex as and with a person with limb differences.


Lichen planus can be managed without treatment. But most cases will require treatment. If you have lichen planus on your skin, it may take a few months or a few years to go away. If you have oral lichen planus, it may take up to five years to go away. Therapy and home remedies can provide relief if you experience any symptoms.


Dandelions, like all flowers, have the proper organs (stamen and pistil) necessary for sexual reproduction, but do not use them. Dandelions reproduce without fertilization; they basically clone themselves, and they are quite successful at it. Look at any lawn for the proof. If dandelions were to revert to sexual reproduction, they might not retain whatever traits they have that allow them to be pests to gardeners everywhere. If flowers can begin reproducing in this manner, does that mean animals, even humans could too? Asexual reproduction can be a good strategy in an environment that is constant if a species is well suited to those conditions. It doesn't take a scientist to figure out that humans wouldn't last long if the condition set forth was no sexual contact with others. Therefore, the human sexual organs are probably in no danger of becoming vestigial.


Biologists believe that for 100 million years the only vertebrates on Earth were water-dwelling creatures, with no arms or legs. At some point these "fish" began to develop hips and legs and eventually were able to walk out of the water, giving the earth its first land lovers. Once the land-dwelling creatures evolved, there were some mammals that moved back into the water. Biologists estimate that this happened about 50 million years ago, and that this mammal was the ancestor of the modern whale. Despite the apparent uselessness, evolution left traces of hind legs behind, and these vestigial limbs can still be seen in the modern whale. There are many cases where whales have been found with rudimentary hind limbs in the wild, and have been found in baleen whales, humpback whales, and in many specimens of sperm whales. Most of these examples are of whales that had only leg bones, but there were some that included feet with complete digits. It was reported recently that whales and hippos were distantly related.


The herpes simplex viruses are latent, meaning they can live in the body without causing symptoms. After the initial infection, the virus gets into the nerve roots and spreads to the sensory nerve ganglia, the junctions where nerves from different parts of the body come together. For the genital area, the ganglia are adjacent to the spinal cord in the lower back. For orofacial herpes (cold sores), the ganglia are located behind the cheek bone.


Achondroplasia is caused by a change (mutation) in the fibroblast growth factor receptor 3 (FGFR3) gene. This prevents bone growth and mainly affects the long bones in the arms and legs. People with achondroplasia have a short stature, with an average height under 4 feet 6 inches (137 centimeters).


The test began with a braking force of 30 N for legs and 20 N for arms. In every subsequent sprint, 10 N was added. During each sprint, participants were encouraged to reach their maximal velocity as soon as possible. This value of peak velocity was recorded and used to calculate F-v relationship (Figure 1).


Potential differences between arms and legs could be explained primarily due to muscle mass and muscle fibre type distribution. Muscle strength or force generating capacity is found closely related to muscle mass (Lanza et al., 2003; Metter et al., 2004) and muscle cross-sectional area (Maugha et al., 1984). It is proposed that upper limbs muscle mass is 22% (Abe et al., 2003) to 25% of lower limbs (Zatsiorsky, 2002). Our data additionally suggest that other factors, e.g. sport discipline in swimming, training, individualized technique and injuries, might also influence these differences. As shown in the Figure 2, there was a case of three female swimmers who had similar force in legs (120 N, 121 N and 122 N), but their corresponding force in arms differed (84 N, 66 N and 36 N) resulting in a wide range of ratio between upper and lower limbs (0.70, 0.54 and 0.30).


Phocomelia is a condition that involves malformations of human arms and legs. Although many factors can cause phocomelia, the prominent roots come from the use of the drug thalidomide and from genetic inheritance.


The symptoms of phocomelia syndrome are undeveloped limbs and absent pelvic bones; however, various abnormalities can occur to the limbs and bones.[2] Usually the upper limbs are not fully formed and sections of the "hands and arms may be missing". Short arm bones, fused fingers, and missing thumbs will often occur. Sometimes hands or fingers will be present but limp due to having no bones or being loosely attached. Legs and feet are also affected similarly to the arms and hands. Individuals with phocomelia will often lack thigh bones, and the hands or feet may be abnormally small or appear as stumps due to their close "attachment to the body".[3]


Thalidomide was released onto the market in 1958 in West Germany under the name Contergan. Primarily prescribed as a sedative or hypnotic, thalidomide also claimed to cure "anxiety, insomnia, gastritis, and tension".[6] Afterwards it was used against nausea and to alleviate morning sickness in pregnant women. Thalidomide became an over-the-counter drug in Germany around 1960, i.e. it could be bought without a prescription. Shortly after the drug was sold, in Germany between 5,000 and 7,000 infants were born with phocomelia. Only 40% of these children survived. [6]
