Aim. The article deals with assessing the effect of different types of motor activity performed during physical education classes on myopia development. Materials and methods. 42 female university students aged 18 years participated in the study. All participants are characterized by acquired uncomplicated myopia. Three homogenous groups of fourteen were formed. The first group performed Nordic walking at PE classes, the second group used a fitness game (Just Dance), the third group was exempted from attending practical PE classes. All female students underwent an ophthalmic examination at the beginning and at the end of the study. The level of physical development and functional abilities of the body was established in all participants. The assessment was conducted based on the dynamics of indicators. Results. It was established that Nordic walking and lessons with a fitness game (Just Dance) did not influence significantly myopia development (р > 0.05). In the first group, myopia development was registered at the level of 0.34 diopter/year, and in the second group – 0.31 diopter/year. However, the comparison of the data obtained with those of the third group revealed a statistically significant difference (р < 0.01). Myopia development in the group exempted from attending practical PE classes was 0.75 diopter/year. Positive dynamics in motor coordination was registered in 57.1% of the first group and 64.3% of the second group. The majority of people from these groups demonstrated an increase in the indicators of the muscular strength of the leading arm and chest excursion. Moreover, more significant changes were registered for the group with a fitness game (Just Dance). The indicators of the third group remained at the same level or even worsened. Conclusion. Different types of motor activity at PE classes reduce  myopia development approximately in the same way. A negative dynamics reveled for certain indicators in the third group can be probably determined by the deficit of motor activity due to huge academic load.

1. Isolated unmated female body-lice were worn in pillboxes between the skin and the clothes. They were kept constantly on the body but, by a simple device, groups of ten were permitted feeding periods of different length. These groups were fed for 4, 8, 12, 16, 20 and 24 hr. per day respectively. Another group of ten were never allowed to feed after the last moult.2. Some of the figures for egg yield were high. Lice in the 24 hr. group were able to maintain a rate of ten eggs per day for 4−5 days at a time.3. No significant difference in longevity or rate of egg-laying was found to exist between the 12, 16, 20 and 24 hr. groups nor between the 4 and 8 hr. groups but a pronounced and significant difference exists between the 8 and 12 hr. groups. Below 12 hr. there is a sharp fall in longevity and rate of egg production. The unfed group all died, without laying, on the third day.4. The rate of laying as shown by the mode increases progressively with increase in time allowed daily for feeding.5. With regard to the mean eggs per louse the position is less clear. It is felt that the 24 hr. group may differ significantly from the 12, 16 and 20 hr. groups but this is uncertain.

The practice of gross motor coordination allows the infant to perform experiential actions to reach maturity, evidencing the passage from practical action to the action of thinking. In this way, feelings and sensations are promoted; discovering one's own body, space and time. The objective of the research was to describe the level of gross motor coordination presented by five-year-old children from I.E.I. N° 0345, Lima and I.E.I. N° 166 "Warma Kuyay", Callao, 2020. The research approach was quantitative, basic type and comparative descriptive design. The technique used was observation and the instrument was the checklist validated through the expert judgment technique and the reliability was 0.911, according to Cronbach's alpha. The results obtained describe the differences presented by five-year-old students in relation to gross motor coordination; the main indicators being the prioritization of the body through movement and the orientation to the development of motor activities, especially in the first years of life. This, because it favors the physical, emotional, socio-affective and cognitive levels, which evidences the differences between the samples investigated.

The aim of the research was to find out the growth rate of the marine lobster, Panulirus versicolor, fed different types of diets.   The experiment was conducted at the Laboratory of Aquaculture Technology, Faculty of Fisheries and Marine Sciences, Sam Ratulangi University.  The experiment was set up  in 3 treatments, which were three different types of diet: treatment-A: papaya leaves, treatment-B: coconut flesh, treatment-C: skipjack-fish flesh.  Each treatment was triplicated.  The tested lobsters were collected from the marine waters of the Likupang village, North Minahasa Regency.  The tested lobsters were weighed at the beginning,  at the end of the experiment, and at the interval of 14 days during the experiment period. The data of the body weight change were statistically analysed using the analysis of the homogeneity of the 3 different linear regression coefficients, between time (X) and the body weight of the lobsters (Y) fed different types of feed, at the confidence test level a = 5% and 1%.  The results show that the body weight of the tested lobsters fed skipjack-fish flesh increased 4 grams after 30 days of the rearing period.  The body weight of the tested lobsters fed papaya leaves decreased 11 g, and the body weight of those fed coconut flesh decreased 3 g after 30 days of the rearing period.  The result of the regression analysis shows, the assumption that the 3 regression coefficients are homogenous is rejected.  In other words, there is a significant difference among the growth rates of the tested lobsters fed different type of diets.  Compared to skipjack-fish flesh, the papaya leaves and coconut flesh significantly slow down the level of the water quality degradation during experiment period.Keywords:  diets, growth, marine-lobster

The purpose of the study is to determine the age-related peculiarities of functional and motor preparedness of students of higher educational institutions. Materials and methods. The study participants were first-year (n=67), second-year (n=66), third-year (n=62), fourth-year (n=45), fifth-year (n=56) male students. The following research methods were used to solve the tasks set: analysis of scientific literature, pedagogical observation, pedagogical testing; index method and medical-biological methods. Pedagogical methods were used to study the peculiarities of functional state of the body and motor abilities of the 1st-5th year students of higher educational institutions; discriminant analysis was used for data processing. Results. There was no statistically significant difference between the 1st-5th year students by the results of test 5 “100 m run”, test 6 “Standing long jump”. The third-year students had the worst results in functional tests and Romberg’s test. The third-year students had the best results in test 7 “Arms’ bending and straightening in a hanging position”. Conclusions. Discriminant analysis made it possible to reveal that the third year of study is the most problematic period in students’ physical education; to answer the question as to the significance of difference between the 1st-5th year students by the level of motor and functional preparedness; to define what indicators most significantly influence the differences between the students’ preparedness; what class the object belongs to based on the values of discriminant variables. The discriminant function structure coefficients show that the most significant difference between the test results of the students in different years of study is observed in coordination preparedness.

The article presents a theoretical analysis and summarizes approaches to the use of kinesioplasty in the training of young football players to optimize motor activity and functional reserves of individual movements. The analysis of the literature showed that the anatomical-physiological and psychological features of the development of the body of young football players are most favorable for the development of most physical qualities of man. Based on the generalization of educational and methodological and scientific literature, it was found that the mechanisms of interaction of posture and arbitrary precise movements are closely interrelated and depend on the state of postural balance and the general center of gravity of the athlete's biomechanics. The expediency of expanding the range of means of the training process of young football players aimed at optimizing their motor activity has been studied. In the sports and training process of young football players found that it is extremely important to develop both cortical mechanisms of motor coordination and the manifestation of various forms of motor coordination in the distal parts of the body, and through muscular activity - changes in spatial, force, temporal characteristics of voluntary movement, biodynamic characteristics of the athlete's posture. It is proved that in order to obtain a positive effect of kinesioplasty methods on the optimization of coordination abilities of young players, it is necessary to restructure the pathological motor stereotype formed as a result of spontaneous development, which adapts the athlete to increase stress and energy expenditure during sports training. And the ability to regulate a variety of parameters of movements is determined by the accuracy of motor sensations and perceptions. The pedagogical experiment was carried out on the basis of FC "Kudrivka". The experiment was carried out by stretching the grass-sickle 2021 rock. It was attended by (n = 30 people) of which (n = 15 people) control group and (n = 15 people) experimental group). The age of the subjects was 8-11 years.

Cooling Methods

The rise in body core temperature associated with continuous exercise in hot and humid environments is known to possess a particularly stressful challenge to the maintenance of normal body temperature and fluid homeostasis. Recent evidence has shown that internal cooling methods, such as drinking cold fluids, are able to lower core temperature and enhance endurance performance in the heat. Pre-cooling (before exercise) and per-cooling (during exercise) methods were use, as ingesting cold fluids is easily implemented on site and provides additional benefit of hydration for athletes. Therefore, this study examines the effectiveness of pre-cooling and per-cooling methods on endurance exercise towards heart rate, rectal temperature, sweat rate, and power output of athletes ingesting different types of cold fluids. 3 female high-performance cyclists were asked to complete a 30km time trial on a cycle ergometer. The familiarisation and experimental sessions were identical, however application of fluid ingestion at 4-5°C before and during exercise differs (plain water = PW, Guava juice = GJ, isotonic drink = ID). Fluid is ingested every 15 minutes during the exercise sessions. As different athletes possess different work intensities, results showed that there is no significant difference on the effects of different types of cold fluid ingestion towards thermoregulation of the body as each fluid succeeded in enhancing athletes’ performance. Therefore, it is suggested that the consumption of any types of fluid at cold temperature could help in body thermoregulation as well as enhancing continuous exercise performance.

Two Bodies ◽  
Traditional Communities

In contemporary anthropology there are two prevailing ideas on the ways in which the human body is culturally thought of: dualism and monism. The first idea is linked to Western societies, and the second is linked to traditional communities, which are the most frequent frame of reference for anthropological research, from the inception of the discipline up to contemporary times. The third, less prevalent idea suggests that there is no substantial difference between these different types of society, that all people, essentially, think about the body in a dualist way. The idea behind this paper is to set a basis for research which might come to show that, indeed, there is no substantial difference between ways in which people conceptualize the body and its cultural aspects in different societies, but that this is not the case because "we are all dualists", but because both dualist and monist cultural conceptualization of the body is contextual, and both of these can be found in societies and cultures which we signify as "modern" or "western".

Abstract Introduction: Down syndrome (DS) of all genetic syndromes is the most common. In Hippotherapy, three-dimensional movements, provided by horse walking, awaken in the body of children with DS a large amount of sensory and neuromuscular stimuli, which directly interfere with overall development and the acquisition of motor skills. Objective: To analyze the effects of an Hippotherapy program on global motor coordination variables in individuals with DS of both genders and to compare individuals with the same syndrome who do not practice Hippotherapy. Methods: 41 individuals participated in the study, 20 of them practicing Hippotherapy (EG) and 21 who did not practice Hippotherapy (CG). The Körperkoordinations test für Kinder (KTK) test was used, consisting of four tasks: Balance on beams, Single-lever jump, Side-jump and Transfer on platform for analysis of motor coordination for individuals. Results: Comparing the groups, a significant difference (p < 0.01) was observed for the Lateral Leap Motor Quotient, the EG presented a better score (114.10) than the CG (88.47), and also in the Total Motor Ratio (EG = 115.10, GC = 102.47). The individuals that practice Hippotherapy presented better results in the global motor coordination, with significant difference (p < 0.05). In EG, 5% had high global motor coordination, 40% good and 55% normal, whereas in CG only 10% had good global motor coordination and 90% normal global motor coordination. Conclusion: It can be emphasized that equine therapy presents benefits of improvement in global motor coordination. Specifically in tasks such as the balance beam, single jump and side jump, besides global motor coordination.

Neuromuscular Development

This little book (first published in 1943 and re-issued with new introduction and bibliography is a useful reminder that human neuromuscular development is not a straightforward, simple, single-line graph but is the result of waves of motor development of different sorts occurring at different stages. The work set out to attempt to correlate various motor activities in the infant with developmental observations in the cerebral tissue of infants. While this was not effectively accomplished the observations did point out that motor development goes through various stages with waxing and waning of different types of involuntary activity, which eventuate into well-integrated motor activity.
