Load Weight

It is well established nowadays the benefits that physical activity can have on the health of individuals. Walking is considered a fundamental method of movement and using a backpack is a common and economical manner of carrying load weight. Nevertheless, the shock wave produced by the impact forces when carrying a backpack can have detrimental effects on health status. Therefore, the aim of this study was to investigate differences in the accelerations placed on males and females whilst carrying different loads when walking. Twenty nine sports science students (16 males and 13 females) participated in the study under 3 different conditions: no weight, 10% and 20% body weight (BW) added in a backpack. Accelerometers were attached to the right shank and the centre of the forehead. Results showed that males have lower accelerations than females both in the head (2.62 ± 0.43G compared to 2.83 + 0.47G) and shank (1.37 ± 0.14G compared to 1.52 ± 0.15G; p<0.01). Accelerations for males and females were consistent throughout each backpack condition (p>0.05). The body acts as a natural shock absorber, reducing the amount of force that transmits through the body between the foot (impact point) and head. Anthropometric and body mass distribution differences between males and females may result in women receiving greater impact acceleration compared to men when the same load is carried.

AimTo compare the available brands of rugby headguards and evaluate their impact attenuation properties at various locations on the cranium, with regard to concussion prevention.MethodsSeven different branded headguards were fitted onto a rigid headform and drop-tested in three different positions. An accelerometer measured the linear acceleration the headform experienced on impact with the ground. Each test involved dropping the headform from a height that generated 103.8 g on average when bare, which is the closest acceleration to the upper limit of the concussion threshold of 100 g. A mean peak acceleration for each drop position was calculated and compared with the bare baseline measurement.ResultsEach headguard demonstrated a significant decrease in the mean peak acceleration from the baseline value (all p≤0.01). Overall the Canterbury Ventilator was the most effective headguard, decreasing the impact force on average by 47%. The least effective was the XBlades Elite headguard, averaging a force reduction of 27%. In five of the seven headguards, the right side of the headwear was the most effective at reducing impact force.ConclusionOverall, the results indicate that it would be beneficial to wear a headguard during rugby in order to reduce the impact forces involved in head collisions. There was also a clear difference in performance between the tested brands, establishing the Canterbury headguard as the most effective. However, only one model of headguard from each brand was tested, so further research evaluating all other models should be considered.

The aim to conduct this research is to enlighten the impact of body image dissatisfaction on an individual’s self-esteem and to examine whether there is a gender difference in this case or not. There are a total of 220 numbers of participants, with equal number of males and females in the sample set. The tool that’d be using here is a modified short version of the Body Shape Questionnaire (BSQ) by Cooper et. Al. in the year in 1987 and The Rosenberg self-esteem scale by Morris Rosenberg (RSES) in the year 1965. The current research proved that whenever there’ll be higher body image dissatisfaction, it’ll result in less self-esteem. Other than that, it stated that females (M= 22.69 and SD= 3.64) have a higher mean score in body image dissatisfaction than and males (M=23.28 and SD= 3.6), therefore, the men have a higher mean score of self-esteem than females.

In this article, an attempt is made to determine the legal status of the human body (organs and tissue) both while a person is alive and after a person dies. The article discusses the points of view of various authors in relation to the possibility of considering the human body, its organs and tissue, after their separation from the body, as objects of a person’s property rights, and also as an object of a person’s non-property rights. The article argues the impossibility of qualifying the human body and the organs that were not separated from it during life as parts – and perhaps critical parts – of the existence of the total human being, as objects of real (property) rights including the rights of the persons themselves. The human body as a single object is a personal non-property benefit. The organs and tissue separated from the body may be considered objects of real rights, but on several conditions: if they were indeed separated from the body and if the person gave permission for this in a will. The specific characteristics of the legal status of the separated organs and tissue of a human being are analyzed as things (possessions) with limited turnover. The specific characteristics of the legal status of the organs and tissue separated from the body as possessions in limited turnover are reviewed as well as the impact of personal non-property rights on this status. The main focus of the article is on the legal status of the human body and the organs separated from it after death in view of the fact that transplantology and postmortem organ donation are becoming more and more widespread. This issue is analyzed in terms of the body as a whole and as it applies to the organs and tissue that are not used for transplantation. The proposal is to base our analysis on the status of the human body after death which as a rule cannot be the object of property rights. The human body is disposed of within the framework of the protection of the personal non-property rights of the deceased, including the right of physical inviolability that covers the organs and tissue separated from the body. The article characterizes the legal nature of living wills when people give instructions as to the procedure of their burial and other means of handling their body, including donation of their bodies to science. The article examines the possibility of the right of ownership to organs and tissue separated from the body after death. This right can exist if a complex legal construct is present, including a direct or assumed living will of the person. The specific characteristics of living acts concerning the possibility of after-death organ and tissue harvesting for further use, including for transplantation purposes, and the differences between such acts and last wills are determined.

The aim of the paper was to investigate health aspects of high altitude trekking such as preparation for the physical exertion during trekking at high altitude, the impact of mountaineering on the daily life before and after the expedition, the effect of high-mountain conditions on health and well-being. It was found that in the pre-departure period trekkers commonly train to ensure that they are physically fit for the expedition. They train alone or under the supervision of a trainer. Self-prepared workouts may turn out to be insufficient due to the lack of appropriate training plans. The most challenging aspects of high altitude trekking for the body include carrying too heavy equipment, dealing with illegibly marked routes, wearing inappropriate clothing, having an unbalanced diet, not having enough water, which can lead to dehydration and infections. Misconduct by other people poses a risk. The specific type of effort involved in mountaineering requires balanced nutrition in terms of both micro- and macro-elements. To find the right combination, one has to either experiment or seek advice from a dietitian. However, relatively few people consult a nutrition coach. Among sanitary problems, the most serious one is inappropriate human waste disposal, the resulting lack of drinkable water. Some of the observed problems result from insufficient regulations regarding the conduct in the mountains and from trekkers’ lack of awareness regarding good practices in such extreme conditions.

Abstract Feeding behaviour is a dynamic process, especially if an individual is dealing with an infection. Here, we used Tenebrio molitor beetles to evaluate the effects of changes in diet macronutrients (protein:carbohydrate) on: (i) feeding behaviour before and after infection (using the entomopathogenic fungus Metarhizium robertsii) in males; and (ii) body condition, measured as the amount of proteins, carbohydrates, and lipids in the body, in males and females. Given that females also depend on the nutrients from the spermatophore, we also addressed the impact on female condition of using spermatophores from males whose diets differed in macronutrients whether they were confronting an infection. We found that males with different diets and regardless of their infection status, and females with different diets, all consumed less of the protein-rich diet but more of the carbohydrate-rich diet. In addition, infection in males produced anorexia. The infection resulted in males and the females they mated with, with fewer body proteins and lipids. This suggests that unlike studies in other insects, T. molitor does not consume large amounts of protein during the adult stage, even during an infection. Females’ condition depended strongly on that of their mates, improving even when paired with infected males. This implies that females may be using the nutrients that the males transfer during mating for maintenance.

AbstractImpact forces, due to the foot contacting the ground during locomotion, can be considered input signals to the body that must be dissipated to prevent impact-related injuries. One proposed mechanism employed by the body to damp the impact is through vibrations of the skeletal muscles. However, there is yet to be direct in vivo measures of muscle oscillations during locomotion. This study investigated the use of 2D ultrasound imaging to quantify transverse muscle oscillations (deep-superficial displacement of the muscle boundary relative to the skin) in response to impact forces elicited by walking and running at a range of speeds. Increases in vertical impact forces with faster walking and running was consistent with changes in both magnitude and frequency in the measured oscillations of the soleus muscle; one of the main human ankle plantar flexors. Muscle oscillations contained more higher frequency components at fast running (50% signal power in frequencies below ~ 14 Hz) compared with slow walking (50% signal power contained in frequencies below ~ 5 Hz). This study provides a platform for ultrasound imaging to examine muscle oscillation responses to impact forces induced by changes in external interfaces such as shoe material, locomotion type and ground surface properties.
