Сharacteristics of age dynamics of general and special physical fitness indicators of acrobats of different genders at stages of long-term improvement

The analysis of the age-related dynamics of the general and special physical fitness indicators of acrobats from different age and gender groups at various stages of long-term improvement is presented, along with the identification of specific changes in the athletes' physical abilities depending on gender and age, with the aim of optimizing the training process and developing the athletes' physical fitness. A group of experts selected 9 tests for the age categories of 9-11, 12-16, and 17-23 years, justifying their choice based on the fact that these tests best and most accurately correspond to the age characteristics, preparation level, and stage of long-term improvement. All selected tests, in terms of their structure, correspond to the specifics of pair acrobatics and are informative for complex coordination sports. In the experimental groups, special authorial complexes of general and special physical fitness exercises were proposed, which, in their structure, are similar to competitive acrobatic movements. This, in turn, led to an increase in the level of leading motor qualities of acrobats in the experimental groups. Considering the gender aspect, the experiment showed a difference between female and male acrobats, which is due to physiological differences, with a focus on the leading qualities characteristic of male and female athletes separately. Age-related features and the dynamics of the general and special physical fitness indicators of acrobats, both in pairs and group events, are characterized by significant changes throughout all stages of long-term improvement. In the 9-11 and 12-16 age categories, an increase in general and special physical fitness is observed, while in the 17-23 age category, these indicators stabilize. Therefore, continuous improvement of the training process is necessary to achieve high sports results. The study revealed the presence of a relationship between technical preparation (evaluated by a universal exercise) and specific indicators of general and special physical fitness. For example, in female acrobats and male acrobats in the 12-15 age category, the test "5 push-ups in a headstand (c)" showed r=0.74 and r=0.78, respectively; in boys aged 17-23 years, the test "push-ups in a lying position (number of repetitions)" showed r=0.82, and in girls, it was r=0.70. The regular relationship between motor qualities is connected with motor skills since acrobatic movement technique is realized through motor skills. To achieve high sports results and optimize the process of athlete development, special physical fitness is one of the leading factors in acrobatics, and its level depends on the individual, age, and gender characteristics of the athletes.

Mosque-Based Empowerment in Providing Services to the Community (Case Study of Al-Abrar Grand Mosque, Makassar City)

The mosque is the house of Allah Subhanahu Wata'ala which is a sacred place and is one of the religious symbols for Muslims. The mosque has the potential to become the center of civilization of the people and also as a place of empowerment that can be maximized. However, the reality that occurs today is that there are still many Muslims who think that the mosque is nothing more than a place of prayer. In fact, if we look back at the time of the Prophet Shallallahu 'Alaihi Wasallam. The mosque plays so many roles such as the center of education, government, economy, and other centers of social life. This research aims at the efforts made by the Al-Abrar Grand Mosque of Makassar City in optimizing the potential of the mosque in providing services to Muslims and to the community in general. This research uses a descriptive qualitative approach that refers to information related to the research topic. The place of this research is located at the Al-Abrar Grand Mosque located on Jl. Sultan Alauddin, Gunung Sari Village, Rappocini District, Makassar City. The results of this study indicate that, the efforts of the Al-Abrar Grand Mosque in providing services to the community are carried out by forming various activity programs, including: a) dawn lectures and breakfast together; b) physical fitness exercises for the elderly (elderly); c) free Al-Qur'an Education Park (TPA), d) zakat, infaq, and alms facilitators; e) services for sick people, and f) services for organizing funerals and takziah lectures. This mosque-based empowerment must continue to be carried out massively and continuously through programs that are in favor of the people and in favor of the community in general. Thus, the mosque can provide services that can bring many benefits from all aspects of life, as exemplified by the Prophet Muhammad Shallallahu 'Alaihi Wasallam.

Effect of Traditional Chinese Fitness Exercises on bone mineral density of middle-aged and elderly people–A systematic review and network meta-analysis

Impact of fitness coach behavior on exercise motivation, commitment, and enjoyment: A longitudinal study.

Fitness coaches seem to play an essential role in the field of exercise as they help prevent sedentary lifestyles and promote overall health, quality of life, and well-being. This study aimed to explore the effects of fitness coaches' behavior perceptions, intrinsic motivation, and enjoyment of exercisers on their long-term fitness and health, as well as their commitment to exercise. A total of 202 individuals participated in the study that was developed over three data gathering occasions (baseline, three months and six months). To this end, three psychometric scales were used as part of a multi-section survey: FCBS-Fit (perception of the fitness coach's behavior), IMIp (intrinsic motivation of exercisers), and PACES (enjoyment in exercise), along with the assessment of four health/fitness variables: anthropometry (i.e., waist-hip ratio), strength (i.e., handgrip strength), flexibility (i.e., sit-and-reach), and cardiorespiratory fitness (i.e., VO2máx.). Overall, the results suggested that the perception of the fitness coach's behavior, the exerciser's intrinsic motivation, and enjoyment were predictors of the health/fitness outcomes, and seemed to be related to the exercise commitment at the end of three and six months. The novelty of this study is the examination of psychological and physiological factors in an integrated and longitudinal manner within the scope of exercise in fitness and health clubs. Therefore, these findings shed light on fitness coaches as an important element in the propagation and maintenance of exercise habits, accomplishment of tangible outcomes by exercisers, health promotion and the fitness sector's growth.

Gym-Related Injuries and its Prevention and Treatment Strategies

In contemporary society, health and fitness have received more and more attention and become an important venue for the public to pursue physical health and good posture. However, in the actual fitness exercise, because most exercisers lack the correct cognition of their own athletic ability, physical condition and movement norms, in the daily exercise process, there will often be unpredictable sports injuries. At the same time, the lack of professional knowledge in the self-treatment of injury leads to the aggravation of injury, which has a negative impact on all aspects of daily life such as my study and work. However, current research on fitness related sports injuries is relatively limited. Through the analysis of the characteristics of sports injuries, understanding the causes of sports injuries in current fitness exercises can provide an important reference basis for how to correctly deal with and prevent common sports injuries, and then improve the fitness consciousness of our people at the social level, and help the construction of a well-off society in an all-round way.

COMBINED ASSOCIATION OF CARDIORESPIRATORY FITNESS AND PHYSICAL ACTIVITY WITH ADOLESCENT INHIBITORY CONTROL

Adolescents undergo intense physical and hormonal changes that impact cognition. Although there is evidence linking cardiorespiratory fitness (CRF) and physical exercise to inhibitory control in adolescents, the combined association of these predictors is limited. Therefore, this study aimed to investigate the combined association of cardiorespiratory fitness (CRF) and physical activity (PA) with inhibitory control in adolescents. A total of 180 adolescents (16.7 ± 1.2 years) from IFPB were included in this cross-sectional study. CRF was assessed using the Progressive Aerobic Cardiovascular Endurance Run (PACER) test, and participants were classified as having “low CRF” or “high CRF.” The Habitual Physical Activity Questionnaire for Adolescents was used to categorize participants as either “exercisers” or “sedentary.” Participants were divided into four groups: “low CRF + sedentary,” “low CRF + exercise,” “high CRF + sedentary,” and “high CRF + exercise.” Inhibitory control was assessed using the modified Flanker task (E-Prime v3.0), considering reaction time (RT) and accuracy rate. A generalized gamma model was used to estimate coefficients (β) and 95% confidence intervals (CI) between groups, with “High CRF + Exercise” as the reference group, adjusting for confounding variables. The “Sedentary + Low CRF” group showed longer RTs in both the congruent (β = 58.3 ms; 95% CI: 15.1; 100.8; p = 0.007) and incongruent phases (β = 59.2 ms; 95% CI: 14.7; 103.6; p = 0.009) compared to the reference group. No significant differences were found in other group comparisons for either the incongruent or congruent phases (p > 0.05). In conclusion, the negative relationship between CRF and sedentary behavior is associated with poorer inhibitory control performance in adolescents.

Habitual and Demographic Determinants of Sleep Quality of Community Development College Students in Tanzania

This study intended to examine personal habits and demographic determinants of sleep quality in a sample of 640 students in the community development colleges in Tanzania. Two questions guiding the study sought to identify personal habits reported by college students that are likely to influence their sleep quality; and explain sleep problems from personal habits and demographic variables of community Development college students. Participants concurrently responded to the Sleep Quality Scale (SQS) and to the Sleep Deprivation scale (SDS). Other items in the questionnaire assessed the demographic information of the participants and personal habits presumed to determine sleep quality. Data were analyzed using techniques such as Principle Component Analysis (PCA), Pearson’s Moment Correlation Coefficient, and Direct Logistic Regression Analysis with an assistance of the Statistical Package for Social Sciences (SPSS). It was found that students’ sleep quality was uniquely explained by personal habits and demographic variables such as the number of times one wakes up at night, level for year of study, sleep deprivation and sex. It was concluded that sleep quality of college students is a product of a multifaceted influences including sex differences and daily habitual practices of the students. It has been recommended that policies should explicitly indicate it as a requirement for students to participate in fitness exercises, early sleep in the hostels as well as late start of studying schedules. In addition, policies should consider establishing psycho-social counselling desks where educative programs on sleep problems and their relationship with mental health should be taught.

Factors Affecting Work Fatigue in Nurses at RSU Dr. H. Yuliddin Away Tapaktuan, Tapaktuan District, South Aceh Regency

The professionalism of a nurse can be seen in carrying out routine work in the field of nursing in accordance with the specified capacity and competence.

Cardiorespiratory Responses to Flywheel-Based Inertial Training Squats With Varying Moments of Inertia.

Mitchinson, CJ, Best, S, Caruso, J, and Bollinger, LM. Cardiorespiratory responses to flywheel-based inertial training squats with varying moments of inertia. J Strength Cond Res XX(X): 000-000, 2024-Flywheel-based inertial training (FIT) has gained popularity as a means to enhance muscle hypertrophy. Other applications, such as aerobic exercise training, remain unexplored. The aim of this study was to determine the cardiorespiratory responses to acute FIT with varying moments of inertia (MOIs). Methods: Overall, 20 (10 M, 10 F) healthy, physically active subjects underwent maximal graded exercise testing and completed 3 bouts of FIT exercise (1 familiarization session and 2 identical data collection sessions). Subjects completed quarter squats (60° peak knee flexion) at a pace of 50 squats·minute-1 until volitional fatigue. Flywheel-based inertial training MOI was increased by 0.005 kg·m2 every 3 minutes until a final workload of 0.020 kg·m2. Heart rate and gas exchange data were collected continuously and averaged over the final 60 s of each stage. Data were analyzed by a linear mixed model. Results: During the final testing session, there was a main effect of MOI to increase heart rate (HR), V̇o2, and RER. Men displayed greater oxygen consumption, but asimilar %V̇o2peak compared with women. We noted a significant inertia × sex interaction where RER tended to be lesser in women at higher MOI. In the final stage of exercise (MOI: 0.020 kg·m2), HR and V̇o2 were approximately 75-80 and 55% of peak, respectively, and RER was approximately 0.95-1.00. Conclusions: FIT quarter squats elicit moderate HR and V̇o2 responses, but near-maximal RER suggests a novel metabolic training stimulus. This exercise may supersede thelactate threshold and may not be sustainable for prolonged times. The physiological and performance effects of training in this manner are unclear.

Investigation of the Effects of 12 Week Aerobic and Fitness Workouts on Individuals Diagnosed with Scoliosis: A Case Study

The study was conducted to examine the effects of aerobic and fitness exercises on scoliosis. A 19-year-old male patient, 1.65 cm tall and weighing 57 kg, with idiopathic S scoliosis was included in the study. The ethics committee report dated 01.07.2021-15974 was received from Muş Alparslan University Ethics Committee. Aerobic and fitness exercises were performed 4 days a week, one day apart, and warm-up exercises were applied before and after. Aerobic and fitness movements such as bench row, reverse butterfly, face pull and low row were included in the exercise program. The exercises were carried out by academics who are experts in their field, under the supervision of an orthopedic doctor. X-rays were used to evaluate the effect of the exercise program on scoliosis. X-rays were taken before and immediately after the exercise program. The orthopedic doctor reported that the scoliosis degree of the patient included in the study was 22.5 degrees before the exercise program, but after the 12-week exercise program, the degree decreased to 21.6 degrees and an improvement of 0.9 degrees was achieved. It was concluded that aerobic and fitness exercises applied specifically to the patient gave positive results in patients diagnosed with scoliosis.

Background/Aims This study to evaluate the effects of different training modalities on blood lipids in type II diabetic patients by Network Meta-analysis, and provide a relevant basis for patients to develop exercise prescriptions to regulate blood lipids. Methods Randomized controlled trials (RCTs) were retrieved from Zhiwang, Wanfang, Wipu, PubMed, EBSCO, Cochrane Library, and Web of Science that were published from the establishment to February 2023. Relevant statistical analyses were performed using Stata 17.0 software and Revman 5.4. Results A total of 35 randomized controlled trials with 2771 patients with type II diabetes were finally included. The results of Network Meta-analysis showed that, compared with the control group, Chinese traditional fitness exercise (CTF), resistance training (RT), and aerobic training (AT) could reduce total cholesterol (TC) levels; CTF, RT, whole body vibration training (WBV), and AT could reduce triacylglycerol (TG) levels; CTF, WBV and AT could increase High-density lipoprotein cholesterol (HDL) levels; CTF, RT and AT could reduce Low-density lipoprotein cholesterol (LDL) levels. SUCRA probability ranking results showed that CTF was the most effective in reducing TC[SMD= −0.57, 95% CI (−0.83, −0.31), p < 0.001], TG[SMD= −0.24, 95% CI (−0.36, −0.12), p < 0.001], LDL[SMD= −0.52, 95% CI (−0.70, −0.35), p < 0.001]; RT was the most effective in increasing HDL[SMD = 0.14, 95% CI (0.03, 0.26), p < 0.05]. Conclusions CTF is more effective in improving TC, TG and LDL levels, while RT is most effective in improving HDL levels.

Research on the application of scientific training methods in the prevention of muscle injuries in young taekwondo athletes

The Taekwondo project originated in the Korean Peninsula. Since it was introduced to my country in the 1990s, it has attracted the attention of many people because of its high degree of appreciation. Taekwondo, characterized by its combative nature and technical demands, poses inherent sports risks, with research indicating that a significant percentage of athletes’ experience sports injuries during their careers. Therefore, this study selected high-level Taekwondo athletes of S University as the survey object, and analyzed the collected data by using literature data method, questionnaire survey method, interview method and other research methods. Aiming at the injury factors of boxing practitioners’ sports injuries, this research proposes the following related countermeasures: (1) The countermeasures against the practitioners themselves and the physical injury factors are: strengthen the protection or exercise of vulnerable parts; the coaches check the physical condition of the students before class; strengthen physical fitness exercises; improve self-protection awareness and ability. (2) The countermeasures against the factors that cause the practitioner’s emotional and rational emotions include: exert the influence of social relations on the practitioner; eliminate fear, cultivate self-confidence; strengthen the cultivation of will quality and self-will! Relaxation and concentration training. (3) The countermeasures for coaches to prevent exercises from sports injuries include: coaches improve their own technical level and teaching skills; reasonable grouping and training methods; leading students to prepare for activities; controlling sports negatives, and technical exercises step by step. (4) Improve the problems of venue facilities that easily cause sports injuries.

A wearable hip exoskeleton for anaerobic exercise in healthy adults

Guidelines encouraging social distancing, limited outings, and remote work due to COVID-19 have increased sedentary periods and reduced levels of physical activity. These habits increase the risk of metabolic diseases, obesity, cardiovascular disease, and diabetes mellitus. The World Health Organization recommends muscle-strengthening exercises as well as regular physical activity to promote overall health. This study investigates the effect of a wearable hip exoskeleton on muscle activity and heart rate during anaerobic exercise in 40 healthy adults (mean age of 40.00 ± 11.51 years; n = 20 females). Bot Fit, a wearable hip-type robotic exoskeleton, was developed by Samsung Electronics Co., Ltd. (Suwon, Republic of Korea) to enhance the effects of both aerobic and anaerobic exercise. All study participants performed a fitness exercise protocol, including knee-ups, good mornings, squats, mountain climbs, kick-backs, reverse lunges, and split jacks, with and without a Bot Fit. To evaluate the effect of anaerobic exercise with the Bot Fit, muscle activity and heart rate were measured during fitness exercises with and without a Bot Fit. Measured muscles were the rectus abdominis (RA), erector spinae (ES), rectus femoris (RF), vastus lateralis (VL), vastus medialis (VM), biceps femoris (BF), tibialis anterior (TA), gastrocnemius medialis (GCM), and gluteus maximus (GM). During anaerobic exercises with the Bot Fit, there was a significant increase in muscle activity compared to exercising without the Bot Fit. Muscle activity increased significantly in the RA, RF, VL, BF and TA muscles during knee-ups; in the ES, BF, and GM during good mornings; in the RF, VL, VM, BF, and GM during squats; in RA, RF, VL, VM, and GM during mountain climbs; in the RA and BF during kick-backs; in the RF, BF, and GCM during reverse lunges; and in the RF and VL during split jacks (p < 0.05). Heart rates showed a statistically significant increase during good mornings, mountain climbs, and reverse lunge exercises while wearing the Bot Fit (p < 0.05). This study demonstrated that anaerobic exercises by healthy adults using a Bot Fit led to enhanced activation of abdominal and lower-limb muscles as well as an improved heart rate, maximizing the effect of anaerobic exercise compared with the same exercise protocol without a Bot Fit. This suggests that use of a Bot Fit can increase the effectiveness of anaerobic exercise in healthy adults.

Analysis of changes in lower limb joints of athletes during the movement of wild horses’ mane parting based on biomechanics

In the era of fitness, more and more young people are familiar with Taijiquan, a kind of physical fitness exercise. By conducting biomechanical analyses of the movements of Taijiquan, it is possible to exercise the body better. Numerous techniques in Taijiquan make it difficult to study each individually. Therefore, this paper studied the movement of “wild horses’ mane parting” in terms of biomechanics by analyzing the joint angle, stiffness, and impulse during this movement. Twenty male athletes were selected as subjects and divided into a professional group and a beginner group according to their training periods. High-speed cameras were used to shoot the “wild horses’ mane parting” movement. The angles of lower limb joints in these athletes were measured to calculate joint impulse and stiffness. The results showed that, compared with the professional group, there were significant differences in the adduction and abduction angle and the internal and external rotation angle between the beginner group and the professional group in the single-leg support movement stage (P&lt; 0.05). There were also significant differences in joint impulse and stiffness (P&lt; 0.05). Compared with beginners, long-term professional practitioners can make their movements more standardized. By comparing movements and data analysis, beginners can make their movements more standardized when practicing Taijiquan and avoid the risk of sports injury. The novelty of this article lies in the use of high-speed cameras to capture athletes’ movements, enabling accurate analyses of their joints and providing effective references for precise training.

The long-term intervention effect and persistence analysis of the baduanjin mental sub -health of college students

In recent years, with the rapid development of society and the increase in academic and living pressure of college students, the psychological sub-health problems of college students have become increasingly prominent. Psychological sub -health refers to the state of the state of health and disease, manifested as a diagnostic criteria for poor individual mental state but not reaching the diagnosis of mental illness. As a special group, college students are in a critical period of psychological and physiological development, and facing multiple pressures such as academics, employment, and social networking. Long -term psychological health state will not only affect its academic and life quality, but also may lead to serious psychological problems such as emotional disorders, anxiety, and depression. Therefore, how to effectively intervene and improve the mental sub -health status of college students have become an important issue for the current psychological health education of colleges and universities. The eight -segment brocade of traditional fitness exercises, as part of ancient Chinese qigong, has gradually been widely used in modern health management in recent years. Baduanjin helps individuals to achieve physical and mental balance by regulating physical movements, breathing and mentality, and have the potential to improve mental health. Existing studies have shown that Baduanjin has certain effects on psychological problems such as relieving stress, improving anxiety, and depression, but there are still fewer long -term intervention effects and continuity research on the healthy sub -healthy health of college students. Therefore, this study aims to discuss the long -term intervention effect and its continuity of the eight -stage brocade of the psychological sub -health of college students, and provide new theoretical support and practical basis for colleges and universities' mental health intervention. This study adopts a random control experimental design. The research object is the college student of the School of Huanghe Science and Technology college. It is included in the standard of the SCL-90 (Symptom Self-Evaluation Table). The research objects are divided into the experimental group and control group. The experimental group participated in the two month Baduanjin, 2 times a week, 60 minutes each time; the control group does not perform Baduanjin to maintain daily life. After the experiment, the SCL-90 symptoms of SCL-90 symptoms and CPSS pressure perception table were performed for the experimental group for 1 month and 2 months to evaluate the continuity of the intervention effect. At the end of the intervention, the psychological sub-health symptoms of the experimental group improved significantly, and the overall scores of the SCL-90 decreased significantly. Compared with the control group, the experimental group improved greater improvement in anxiety, depression, and pressure perception. Especially in terms of anxiety and depression, the improvement of the experimental group is particularly significant. In summary, this study provides a wealth of experimental data and theoretical basis for the long -term intervention effect and sustainability of the Baduanjin for the healthy sub -health of college students through random control experiments. The results of the research not only provide an effective means of intervention for colleges and universities, but also open up a new direction for the modern application of traditional fitness methods. In the future practice, Baduanjin is hoping to become an important means of psychological and health intervention in colleges and universities, and provide theoretical basis for college students' physical and mental health.

E-waste driven eco-friendly highly sensitive wearable capacitive sensors for physical activity monitoring and sign language recognition

Owing to the continual and rapid advancement in technology, there has been a significant surge in electronic waste (e-waste) in recent decades, resulting in a harmful impact on our environment. Due to the growing demand for battery-powered devices, non-rechargeable batteries are a significant source of e-waste. This study describes fabricating a paper-based graphite strain sensor that is eco-friendly, inexpensive, biodegradable, and sensitive to the applied strain. Readily accessible materials are employed to design and fabricate MIDC strain sensors. The Modified Interdigital Capacitor (MIDC) structure is formed on basic printing paper, and the conductive substance made with the ink of a gel pen and graphite from a drained dry cell is painted on the paper and used as electrode material. The suggested sensor has a high gauge factor value of 1998.578 and fast response and recovery time of 112 ms and 100 ms, respectively. The proposed prototype has also been utilized to inspect fitness exercises and physical activities on the human body, inspiring the potential for its integration into wearable systems for various applications. Reliable detection and differentiation of finger positions are achieved, highlighting the sensor's potential for more advanced sign language applications. It’s a good option to integrate the suggested strain sensor in wearable systems, such as telemedicine systems, electromechanical detection, healthcare, and physical activity monitoring of humans.

Features of the development of strength and flexibility of middle school children by means of fitness with elements of martial arts

The article is devoted to the study of the peculiarities of the development of flexibility and strength of schoolchildren aged 13-14 under the influence of martial arts fitness. The purpose of the study is to determine the effectiveness of using fitness exercises with elements of martial arts for the development of flexibility and strength abilities of secondary school children. The research involved 20 boys and 20 girls who studied in the 8th grade of a secondary school. The following methods were used to solve the research tasks: studying and analyzing literary sources on the research topic; pedagogical experiment; pedagogical testing of the level of physical abilities development, methods of mathematical statistics. To conduct the pedagogical experiment all participants of the experiment were divided into two groups: experimental (10 girls and 10 boys) and control (the same composition). The essence of the experiment was that for children who were included in the experimental group during 5 weeks during physical education lessons an experimental variable module on fitness with elements of martial arts was introduced. When developing the variable module on martial arts fitness, we adhered to the requirements for variable modules in the current physical education curriculum for schools. Girls and boys in the control group attended physical education classes based on the educational material of the variable module gymnastics. The study proved that the use of a variable fitness module based on the use of classical aerobics exercises and martial arts elements during physical education lessons in middle school contributes to a statistically significant improvement in flexibility (forward bending) and strength (flexion and extension of the arms in a lying position and lifting the torso from a lying position in 30 seconds). At the same time, such exercises are emotional and can have a positive impact on adolescents' functional fitness, well-being, and mood.

Exploring Whole-Body Vibration Transmission Through the Human Body in Different Postures on a Large Vibration Platform

The positive effects of whole-body vibration exercise in rehabilitation, sport, fitness and preventive medicine have led to a proliferation of vibrating platforms. However, discrepancies have been claimed between the manufacturers’ vibration parameters and the vibration applied by the platforms. In addition, the dimensions, materials and motors used in their manufacture mean that each platform behaves differently. These factors can influence their transmission to the human body and, consequently, their effects. Thus, measured vibration parameters were recommended to report the vibration parameters as accurately as possible. Therefore, the present study aimed to determine the feasibility of a large vibration platform. Measurements of vibration parameters and their transmission were added. These parameters were measured using six accelerometers (platform, ankle, knee, hip, third lumbar vertebra, and head) throughout five postures (toe-standing, erect, high squat, deep squat, and lunge) and three vibration frequencies (20 Hz, 25 Hz, and 30 Hz). On the platform, peak accelerations of 1 ± 0.2 g, displacements of 1 ± 0.1 mm at 20 Hz and 25 Hz and 0.6 mm at 30 Hz, and a frequency from the setting of +0.5 Hz were obtained. In the human body, peak accelerations can exceed 2 g, and these transmissibility amplifications were found at the ankles and knees. However, at the hip, accelerations plummet and transmissibility attenuation occurs all the way to the head. The signal purity was highly satisfactory, although at the hip and third lumbar vertebra when adopting the toe-standing and lunge, some less satisfactory results were found—especially at 20 Hz and 30 Hz. Present data indicate that the long vibration platform can be used for exercise and health in a safe way, although its specific behaviours have to be taken into account in order to optimise its applicability.

Effect of Programed Walking Exercise Using Bot Fit in Younger Adults

IntroductionPhysical inactivity and sedentary behavior both increase the risk of chronic disease and mortality. Regular participation in physical activity and reducing sedentary behavior play important roles in maintaining physical health and disease prevention.ObjectiveThe purpose of this study was to investigate the effect of programed walking exercise using a wearable hip exoskeleton, Bot Fit on muscle strength, muscle effort, and the kinematics of the pelvis in younger adults.MethodsWe designed three parallel experimental conditions and randomly assigned participants to one of three groups: those assigned to exercise using an interval program of Bot Fit (interval group), those who used a power program of Bot Fit (power group), and a control group who exercised without Bot Fit. A total of 45 young adults participated in 18 exercise-intervention sessions over six weeks, and all participants were assessed at two time points: before and after the 18 exercise sessions. Each assessment evaluated muscle strength, muscle effort, and the kinematics of the pelvis during walking. In addition, the number of steps, distance, energy expenditure, and heart rate for 30 min during the exercise sessions were recorded.ResultsA significant increase in the maximum voluntary contraction (MVC) of the left biceps femoris (BF) was evident in the interval group, while significant changes in the MVC of the bilateral BF were seen in the power group after Bot Fit exercise. A significant decrease of muscle effort in the right BF in the interval group and right lumbar erector spinae and bilateral BF in the power group were also observed. In addition, the symmetry index of pelvic tilt significantly improved in the interval group, and greater exercise volume and intensity in both the interval and power groups compared with the control group were confirmed as measured by the number of steps, distance, energy expenditure, and heart rate.ConclusionsThe results of this study confirmed the beneficial effect of programed walking exercise using the Bot Fit on muscle strength of trunk and lower extremities, muscle effort, and pelvic movement symmetry in younger adults. Personalized exercise programs can be provided for younger adults using various resistance or assistance modes of robotic device with the Bot Fit.Trial RegistrationClinicalTrials.gov, NCT05862077.
