Discriminant analysis: peculiarities of impact of sports specialization on 3rd-year female students’ functional and motor fitness

Background and Study Aim. The objective of the study was to determine the peculiarities of impact of sports specialization on 3rd-year female students’ functional and motor fitness. Materials and methods. The study involved 3rd-year female students of the Donbas State Engineering Academy in Kramatorsk, who practiced badminton (n = 43), aerobics (n = 43), and callanetics (n = 43). To solve the tasks set, the following research methods were used: analysis of scientific literature, pedagogical observation, pedagogical testing; index method and medical-biological methods. Pedagogical methods were used to study the peculiarities of students’ functional state of the body and motor abilities; for data processing discriminant analysis was used. Sectional classes were held in groups according to the schedule – twice a week. Results. The study revealed the peculiarities of impact of attending badminton, aerobics, and callanetics sports sections on the level of 3rd-year female students’ functional and motor fitness. The female students who play badminton show better results in the 100-meter dash and the Standing long jump. In the exercise “Push-ups”, better results are shown by the female students who do aerobics. Conclusions. The results of classification of students by the level of motor and functional fitness and the analysis of multidimensional averages (centroids) point to the peculiarities of dynamics of female students’ state depending on sports specialization. The results of the following tests are most important for differentiated assessment of the state of motor and functional fitness at the first level: Romberg test (r = 0.662), 100-meter dash (r = 0.491), Push-ups (r = 0.491). At the second level – Stange test (r = 0.417), Standing long jump (r = 0.412).

Brain Oxygenation in Post-concussion Combat Sport Athletes

Purpose: Investigate the feasibility of a non-invasive method to evaluate the physical and cognitive repercussions of long-lasting post-concussion effects in professional combat sports athletes. To help athletes return to professional combat, there is a need for unbiased objective tools and techniques used as a prognostic method of recovery after Sport Related Concussion (SRC).Methods: Six mild Traumatic Brain Injury (mTBI) athletes, age 20 ÷ 43 yr (1 female, 5 males) and 7 not concussed (NC) participants (amateur), age 24 ÷ 38 yr (3 females, 4 males), were tested Inspired/expired gas concentration, Cerebral changes in oxygenated hemoglobin (Δ[HbO2]) and deoxygenated hemoglobin (Δ[HHb]) were measured using near infrared spectroscopy (NIRS) with a 3-step protocol: rest before maximal oxygen uptake (VO2max) test, hypercapnia, and recovery after VO2max test. The brain oxygenation and respiratory parameters of both sample sets were calculated using a non-parametric test (Mann-Whitney U test). Aerobic fitness outcome was quantified through mean average using the Bruce test. Participants performed Fitt's test using a laptop and analysis of medio-lateral and anterior-posterior range of oscillation was carried out via a force platform Romberg test.Results: mTBI group showed statistically significant differences in saturated hemoglobin Δ[HbO2] (p < 0.001) during rest and recovery phase after maximal incremental exercise, in medio-lateral sway eyes open (p = 0.008, NC 25.35 ± 4.11 mm and mTBI 17.65 ± 4.79 mm). VO2max revealed no significant differences between the two groups: NC 47.47 ± 4.91 mTBI 49.58 ± 5.19 ml/kg/min−1. The 2 groups didn't differ for maximum power output (NC 220 ± 34, mTBI 255 ± 50 W). End-tidal fractional concentration of O2 (FetO2 NC15.20 ± 0.41, mTBI 16.09 ± 0.68) throughout hypercapnia, saturated blood hemoglobin (Δ[HbO2]) revealed significant differences with the mTBI group. No differences emerged from Fitt's test.Conclusions: It emerges that NIRS is able to reveal differences in long time outcomes of mTBI. The medio-lateral variations cannot be considered as a marker of long-term damage in athletes specifically trained for balance.

An Assessment of Balance through Posturography in Healthy about Women: An Observational Study

The incidence of falls in adults constitutes a public health problem, and the alteration in balance is the most important factor. It is necessary to evaluate this through objective tools in order to quantify alterations and prevent falls. This study aims to determine the existence of alteration of balance and the influence of age in a population of healthy women. Static posturography was performed on 49 healthy adult women with no history of falls in four different situations using the Romberg test with the NedSVE/IBV® platform. The variables studied were the body sway area and the anteroposterior and mediolateral displacements. The situation of maximum instability occurred in RGC (p = 0.001), with a significant increase in anteroposterior oscillations regarding the ML (p < 0.001), with no correlation to age. Age alone does not influence the balance in the sample studied, other factors must come together to alter it. The joint cancellation of visual and somatosensory afferents could facilitate the appearance of falls, given that it is a situation of maximum instability. Proprioceptive training is interesting as a preventive strategy for falls.

Physical Impairments, Sensory Disturbance and Functional Ability in Cancer Patient With and Without Chemotherapy-induced Peripheral Neuropathy Symptoms

ObjectiveThe present study examined the objective and patient-reported measures of physical impairments, sensory disturbance and functional ability between cancer patients with and without chemotherapy-induced peripheral neuropathy (CIPN) symptoms.Methods41 cancer survivors exposed to neurotoxic chemotherapies were conveniently recruited and completed a single cross-sectional assessment of patient-reported outcomes (VAS for pain intensity and ABC scale) and objective assessments (SWM test, TUG test, 5xSTS test, Romberg test with eyes open and eyes closed, 6MWT, and FAB scale).ResultsCancer patients who had undergone chemotherapy with CIPN symptoms did significantly worse in the SWM test, TUG test, 5xSTS test, Romberg test with eyes closed, 6MWT, FAB scale, and ABC scale (p<0.05) when compared with cancer survivors without CIPN symptoms.ConclusionCancer survivors with CIPN symptoms have lower physical performance, sensory perception, and functional ability, which may increase the risk of falling and disability. These findings further emphasize the need for effective rehabilitation and interventions to treat CIPN symptoms and related physical impairment and functional deficits.

INFORMATIVE VALUE OF COMPUTER STABILOMETRY IN THE DIAGNOSIS OF VIBRATION DISEASE FROM THE EFFECTS OF GENERAL VIBRATION

A statistical analysis of stabilometric study results of 50 male patients with vibration disease (VD) from the effects of general vibration (GV) (average work experience 26,7±6,2) has been carried out. The control group (CG) included 50 men who have not been exposed to the general vibration. The compared groups were comparable by age: the average age of patients with vibration disease was 56.34+5.15, patients of the control group-58.22+-7.05. The study of the support symmetry and equilibrium function was carried out using the Romberg test on the St-150 stabiloplatform (Biomera, Moscow) in a vertical stand with European installation of feet in the positions of open (OE) and closed eyes (CE). A comparative analysis of the parameters of support symmetry in patients with VD from GV revealed a statistically significant sagittal asymmetry in the phases of OE and CE than in individuals of CG. Among the balancing parameters, the most informative parameters of computer stabilometry in patients with VD from GV were: an increase in the area of the statokinesiogram, a decrease in energy efficiency in both phases of the study, and an increase in the speed of the statokinesiogram in phase with CE. Computer stabilometry can be recommended as an additional objective research method in the diagnosis of early stages of VD from GV to improve the quality of periodic medical examinations.

Comparative Analysis of Psycho-physiological Parameters of the Deaflympic Karate Champion and Healthy Karate Women

The article compares psycho-physiological indicators of an elite athlete in karate - the champion of the Deaflympics and healthy, highly qualified athletes. The researched indicators were: work efficiency, degree of employment, mental stability, time of simple reaction to a moving object, reaction to a moving object, frequency of movements, the reaction time of choice, Romberg test, concentration and switching of attention according to the Bourdon test. For the analysis, 24 measurements of psycho-physiological indicators of the researched sportswoman were compared with corresponding indicators of highly skilled healthy karate girls, 29 people in total. The measurements of the studied athlete’s indicators were performed during the annual macrocycle at the beginning of a series of shock microcycles, which meant that she was in her optimal physical and psychological shape. It was found that the studied karate person has an invalid type of nervous system, which is not typical for this sport. Work efficiency, speed of work and mental stability also differ in favour of healthy karate women.

CHARACTERISTICS OF STATIC BALANCE IN BADMINTON PLAYERS OF VARIOUS AGE AND QUALIFICATION GROUPS

The ability to maintain static balance in badminton players may decrease due to prolonged asymmetric locomotor loads while training. The aim of this study was to assess the peculiarities of maintaining static balance in badminton players of various age and qualification groups. Materials and Methods. The study involved 88 badminton players, who had various sports experience and skills. Static balance was assessed with a stabilographic hardware-software complex “Stabilan 01-2” and the Romberg test (eyes open/eyes closed) during the preparatory and transitional periods of the annual training cycle. The authors assessed the following indicators: MO(x), mm; MO(y), mm. Statistical data processing was carried out using Microsoft Excel and STATISTICA 8.0 data analysis package. To compare the samples, we used the parametric Student’s t-test. Normality of distribution was checked with the Shapiro-Wilk test. Statistical data represented both arithmetic mean and standard error of the mean. The parameters were considered statistically significant at p<0.05. Results. Badminton players of all groups under consideration demonstrated an asymmetry of the vertical posture with center-of-pressure movement to the right in both tests (eyes open/eyes closed) (p<0.05). In badminton players, aged 8–12, the posture stereotype was characterized by a forward center-of-pressure movement (p<0.05), in adolescents, aged 13–16, and young people, aged 17–21, we observed backward center-of-pressure movement (p<0.05). Conclusion. Badminton players, aged 8–12, demonstrated a higher level of maintaining static balance with visual control. Adolescents and young people are able to maintain body balance with visual deprivation, which, apparently, indicates more perfect mechanisms of proprioceptive and tactile sensitivity. Keywords: badminton, asymmetric motor loads, static balance. Способность к сохранению статического равновесия тела у бадминтонистов может снижаться вследствие длительных асимметричных двигательных нагрузок в тренировочном процессе. Целью исследования явилась оценка особенностей сохранения статического равновесия у бадминтонистов различных возрастно-квалификационных групп. Материалы и методы. В исследовании приняло участие 88 бадминтонистов различного спортивного стажа и квалификации. Статическое равновесие тела оценивалось с помощью стабилографического аппаратно-программного комплекса «Стабилан 01-2» с использованием пробы Ромберга в тесте с открытыми и закрытыми глазами в подготовительный и переходный периоды годичного тренировочного цикла подготовки. Оценивались следующие показатели: MO(x), мм; MO(y), мм. Статистическая обработка данных проводилась с использованием программы Microsoft Excel и пакета анализа данных Statistica 8.0. Для сравнения выборок использовался параметрический t-критерий Стьюдента. Нормальность распределения проверялась с помощью критерия Шапиро–Уилка. Статистические данные представлены как среднее арифметическое и стандартная ошибка среднего. Исследуемые параметры считались статистически значимыми при p<0,05. Результаты. У бадминтонистов всех исследуемых групп отмечена асимметрия вертикальной позы с девиацией центра давления вправо как в тесте с открытыми, так и в тесте с закрытыми глазами (р<0,05). У бадминтонистов группы второго детства (8–12 лет) стереотип позы характеризовался смещением центра давления вперед (р<0,05), у испытуемых подросткового (13–16 лет) и юношеского (17–21 год) возрастов отмечена девиация центра давления назад (р<0,05). Выводы. Для бадминтонистов группы второго детства при зрительном контроле характерен более высокий уровень сохранения статического равновесия, тогда как спортсмены подросткового и юношеского возрастов и при депривации зрения способны удерживать равновесие тела, что, по-видимому, указывает на более совершенные механизмы проприоцептивной и тактильной чувствительности. Ключевые слова: бадминтон, асимметричные двигательные нагрузки, статическое равновесие.

Manual Acupuncture Effect on Vertigo and Tinnitus in Patient with Labyrinthitis: A Case Report

Labyrinthitis is an inflammatory disease of the inner ear perilymphatic cavity and the most common cause of prolonged spontaneous vertigo. Other symptoms are tinnitus and sensorineural hearing loss. Acupuncture is one of the non-pharmacological therapeutic modalities to improve symptoms of labyrinthitis. A 54-year-old woman complained of vertigo that is preceded by tinnitus in both ears since the last 6 months. She was diagnosed with labyrinthitis. Had taken amoxicillin and decadryl for 5 days, betaserc and dimenhydrinate when she felt dizzy, and amlodipine as a routine drug for her hypertension. Physical examination showed vital signs within normal limits, grade 2 obesity, positive Romberg test, and THI score 18. Manual acupuncture was performed at acupoints GV20, GB20, TE17, TE21, SI19, GB2, GB8, TE5, LI4, KI3, PC6 and LR3 with 20 minutes retention. After the first therapy, vertigo complaints disappeared and after 12 treatments (twice a week), frequency and intensity of tinnitus became less, with THI score of 6. Therefore, acupuncture can relieve vertigo and improve tinnitus which can be seen by a decrease of THI score. Keywords: acupuncture, labyrinthitis, tinnitus, vertigo
