A history study on the reason why scientific theory was separated from aerobic dance in Japan : focusing on the process of aerobic dance\u27s acceptance (1982-1986)

This study examines how aerobic dance was separated from aerobics theory and lead to injuries to many people on the process of aerobic dance’s acceptance. In addition, we figure out why it happened from internal and external causes. In the early 1980s, aerobic dance was introduced into Japan and spread across the whole country. Afterwards, some enterprises started to make videos and TV programs about aerobic dance, and incorporated aerobic dance into the advertising campaign about their own corporations and merchandise. In the meanwhile, leotard, widely used for training clothes of Yoga, Jazz dance, also is used for Aerobic dance. And sexy image began appearing in aerobic dance with the change of leotard. In that way, Aerobics theory, the essential part of aerobic dance, was ignored, because people only pay attention to the topicality and sexy image of aerobic dance after its introduction to Japan. On the other hand, in the first half of 1980s, people in aerobic dance field started to learn the ropes about the training of program and instructor. Although professional aerobic dance mentors were not enough, besides the research on program did not follow up, yet the program and unsystematic guidance spread with the increase of aerobic dance studio and Fitness club. Eventually, All-Japan Aerobic Championships were held in 1983, then“aerobic” was developed as a competitive sport. Many events and athletic meetings were held everywhere in Japan. Thus, Aerobic dance became a competitive sport as the name of “aerobic”. So, the public thought aerobic dance is a very violent sport, and instructors assess it with the scores, leading to the situation that amateurs prefer violent aerobic dance. For the internal and external causes above, in the first half of 1980s, aerobic dance was separated from aerobics theory on the process of aerobic dance’s acceptance

KINETIC COMPARISON BETWEEN HIGH-IMPACT AND LOW-IMPACT STEP AEROBIC DANCES

Step aerobic dance is one of the most popular aerobic exercises. There are two kinds of aerobic dances, high-impact (HI) and low-impact (LI). High-impact aerobic dance is defined as the exercise involving bouncing, hopping or jumping in which both feet are often taken off the ground. Low-impact aerobic dance is defined as the exercise in which there is always one foot on the ground during the exercise. One of the major causes of sports injury in aerobic dance is overuse injuries of the lower extremity (60%; Francis et al., 1985; Mutoh et al., 1988). This high injury rate in aerobic dance may be due to the repetitive, high joint loads in the lower extremities. Therefore, the purpose of this study was to evaluate the effect of impact level on the joint kinetics of lower limb in step aerobic dance

Examining of the effects of aerobic dance and step dance exercises on some hematological parameters and blood lipids

The aim of the study was to examine the the effects of aerobic and step dance exercises on hematological and blood lipids parameters. 32 university students were voluntarily participated in this study. They were randomly assigned to aerobic dance (N=16) and step dances (N=16). All groups were participated an hour aerobic or step dance exercise session 2 times in a week during 3 months. Wilcoxon Sign test was used to analyze pretest and posttest results of variables. As results, significant differences were found in the pre- and post-intervention scores for triglycerides (TC), red blood cell (RBC), and hematocrit (HCT) in Step dance group. Although there were decreases in triglycerides levels for both aerobic dance and step dance groups, only significant reduction was found in step dance group. Step dance exercises was better than aerobic dance in terms of increasing RBC and decreasing cholesterol, low density lipoproteins (LDL) cholesterol level. Aerobic dance exercises were better than step dance in terms of increasing high density lipoproteins (HDL). Moreover, when comparing the level of decreasing of Hemoglobin (HGB) significantly, aerobic dance group were better than step dance group. HCT increased significantly more in step dance group as compared with aerobic dance group. Step dance cause more increment than aerobic dance in terms of platetes (PLT) level. The data of this study indicates that step dance is more effective than aerobic dance in terms of decreasing LDL cholesterol, triglycerides and cholesterol for university students

The Effects of a Six-Week Aerobic Dance Programme on Selected Fitness Components and Waist-Hip-Ratio in Adult Males

This study examined the effects of a six-week low-impact aerobic dance on selected fitness components (trunk flexibility, leg power and abdominal muscle endurance) and waist-hip-ratio (WHR) in adult males. A total of fifteen (15) Lagos State University male undergraduates (age range: 19-28 years) from the Faculty of Education volunteered to take part in the study. The one-group pre-test - post-text quasi-experimental research design was employed. Both pre-test and post-test measurements were taken from each participant under the same conditions. Participants were all exposed to a low-impact aerobic dance for a duration of six weeks. While the descriptive statistics of mean, range and standard deviation were used to describe the data; inferences were drawn using the Students‟ paired T-test. Results revealed that a six-week low - impact aerobic dance programme can significantly reduce the waist-hip-ratios, improve trunk flexibility, leg power and abdominal endurance/strength in male undergraduate students. Keywords: Hypokinetic diseases, Low-impact aerobic dance, Sedentariness, Waist-hip-rati

COULD LONG-TERM EXERCISE IMPROVE THE OBSTACLE-CROSSING ABILITY OF ELDERLY WOMEN? EFFECTS OF TAI CHI AND AEROBIC DANCE EXERCISES

The purpose of this study was to evaluate the effects of long-term exercises (TaiChi (TC), aerobic dance) on the obstacle-crossing ability of elderly women, as well as to identify whether the exercise could considerably improve stability. Forty-five elderly women include TC, aerobic dance and no exercising groups participated in our study. They walked a short distance to cross the obstacle (30% of leg length). Results showed that long-term exercise had a positive effect on muscle strength and the practitioners used an obstacle-crossing strategy that increasing the force in medial–lateral and anterior-posterior directions of the trailing foot to cross obstacle. The TC strategy was better than aerobic dance in improving balance and increasing the height of the leg during obstacle-crossing

Effects of combined aerobic dance exercise and honey supplementation on bone metabolism, muscular strength and immune functions in women

INTRODUCTION: Although combination of physical activity with supplementation has being investigated on its effects in maintaining and enhancing bone health, little is known about the effectiveness of combination of aerobic dance exercise with honey supplementation on bone metabolism markers, muscular strength and immune function in women. PURPOSE: The aim of this study was to investigate the effects of combined aerobic dance exercise and honey supplementation on bone metabolism, muscular strength and immune function in women. METHODS: Forty four subjects, healthy sedentary women (25-40 year-old) were age and body mass matched, and subsequently being assigned into four groups with n=11 per group: Control group (C), honey supplementation group (H), aerobic dance exercise group (Ex) and combined aerobic dance exercise with honey supplementation group (HEx). Aerobic dance exercise was carried out for one hour per session, three times per week for eight weeks. Honey drink was consumed by H and HEx groups, in a dosage of 20g of honey diluted in 300ml of plain water, for 7 days per week for a total of 8 weeks duration. In HEx group, the subjects were required to consume honey drink 30 minutes before performing exercise on the exercise days. Before and after 8 weeks of experimental period, subjects’ anthropometry, muscular strength and power were measured. Meanwhile, blood samples were taken in order to determine the concentrations of serum total calcium, osteocalcin (bone formation marker), serum C-terminal telopeptide of type 1 collagen (1CTP) (bone resorption marker), and parathyroid hormone (PTH), and immune functions determination through full blood counts and immunophenotyping measurements. RESULTS: The end of 8 weeks of experimental period, combination of aerobic dance exercise with honey supplementation (HEx) exhibited more discernable beneficial effects on left and right lower limb peak torque (muscular strength) and power compared to the other three Ex, H and C groups. Regarding bone metabolism, the percentage of increment in 1CTP, a bone resorption marker, and PTH concentrations in HEx group were the lowest compared to the other experimental groups. With regards to immune functions, significant increases in T cytotoxic (CD8) and total B cells (CD19) counts (p<0.05) were observed in HEx group after 8 weeks of experimental period. Additionally, the percentage increase in lymphocyte counts, T helper (CD4), T cytotoxic (CD8) and total B cells (CD19) counts after 8 weeks were the highest in HEx group compared to the other three experimental groups. CONCLUSION: The results of present study suggest that combination of aerobic dance exercise and honey supplementation elicited more beneficial effects on bone health, muscular strength and power, and immune functions generally compared to aerobic dance exercise or honey supplementation alone in sedentary women

Aerobic Dance on an Air Dissipation Platform Improves Cardiorespiratory, Muscular and Cellular Fitness in the Overweight and Obese Elderly

Background: Obesity is a global health problem associated with a high number of comorbidities that decrease functional capacity, especially in elderly people. Aerobic dance is considered a viable strategy to prevent the effects of aging, mainly in obese and overweight elderly people. This study aimed to evaluate the effects of aerobic dance on an air dissipation platform (ADP) on body composition, oxidative stress and muscular and cardiorespiratory fitness in elderly people. Methods: In total, 32 elderly adults (67.1 ± 3.6) were divided into 3 groups based on body mass index: healthy (HG), overweight (OWG) and obese (OG). Training program of aerobic dance on an ADP was carried out twice a week for 12 weeks. Results: OWG (p = 0.016) and OG decreased their weight (p < 0.001). There was a significant decrease in malondialdehyde concentrations in all experimental groups (p < 0.05). OWG and OG significantly improved their peak oxygen uptake (p < 0.01). HG increased the vertical jump height (p < 0.05), and HG and OG improved the power output of the lower extremities (p < 0.05). Conclusions: The aerobic dance on an ADP may be an effective alternative to lose weight, prevent oxidative stress and improve cardiorespiratory fitness in obese and overweight elderly people

Twelve Weeks of Aerobic Dance Impact on Cardiovascular Parameters of Male Obese Adults

The purpose of this study was to investigate the twelve weeks of aerobic dance impact on cardiovascular parameters of male obese adults. To achieve sixty (60) obese men were selected as samples for the experimental study. These subjects age ranged between 25 and 40 years. For this, a purposive sampling technique was used. Those who are diagnosed as obese by the consultant physician of the Pondicherry institute of medical sciences if the body mass index (BMI) was more than normal limits &gt; 27.8. Further, the sample subjects were randomly assigned into almost two equated groups, namely Aerobic dance group (ADG) (n=30) and Control group (CG) (n = 30). All these subjects were residing within radius of one to three kilometers range in grater Puducherry. Blood pressure and heart rate was selected as criterion variable and measured with Omron Blood pressure and heart rate monitor. The aerobic dance training was administered 60 minutes per day for 6 days in a week for total period of 12 weeks. The data was collected before and after 12 weeks of training and analysed using ANCOVA. The result of the study showed that systolic and diastolic blood pressure between the groups was significant, F (1,57) = 7.69 and 4.488, indicating that after adjusting pre-test scores, there was a significant difference between the two groups on post- test scores on systolic and diastolic blood pressure. In contrast, heart rate found to be not significant, F (1,57) = 3.33. The findings of the study show that systolic and diastolic blood pressure tends to decrease as a result of aerobic dance training. It is concluded that aerobic dance is the proper physical activity form for 30-40 years old men obese subjects for developing cardiovascular system capacity. The stress on the cardiovascular system is minimised due to aerobic dance which was fun and recreative. This might improve the life status of the obese subjects

Effect of Selected Yogic Practices and Aerobic Dance on Health Related Physical Fitness Variables among Nicobari Women Students

The purpose of the study was to find out the effect of selected yogic practices and Aerobic dance on health related physical fitness variables among Nicobari women students. Seventy-five students were selected from JNRM College, Port Blair, Andaman&amp; Nicobar Island. The age of the subjects ranged from 18 to 22 years. The selected subjects were divided into two experimental groups and one control group by random. Group I underwent Yogic practices in selected asanas and pranayama; Group II underwent Aerobic dance and Group III acted as Control Group for three alternate days in a week for a period of six weeks. The dependent variables selected for this study were Cardio vascular endurance, Muscular strength/endurance, Flexibility and Body composition. The dependent variables namely Cardio Vascular Endurance measured by Cooper?s 1-mile run/walk test, Flexibility measured by Sit and Reach Test, Muscular Strength/ Endurance measured by Bent Knee Sit ups and Body Composition measured by Skin fold caliper. The data were collected from each subject before and after the training period and statistically analyzed by using dependent „t? test and analysis of covariance (ANCOVA). It was found that Aerobic dance group was found to be better in improving cardio vascular endurance and muscular strength/endurance when compared to the yogic practices group. Yogic practices group was found to be better in improving flexibility when compared to the aerobic training group. Both yogic practices and aerobic dance groups were developed the body composition equally

Using dance to improve executive funcitoning [i.e. functioning] in older adults

Can age-related declines in cognition be reversed? Previous research has used two fundamentally different approaches for addressing this theoretical question, mentally stimulating activities and aerobic exercise. The current study extends this prior research by combining these two approaches through the use of aerobic dance with steps of varying cognitive difficulty. The cognitive performance of three groups of older adults was measured before and after engaging in six weekly dance classes. One group completed an aerobic dance class with simple steps intended to create little cognitive demand. A second group completed an aerobic dance class involving more complex, cognitively challenging choreography. A final group did not receive any dance training between pre- and post-testing. It was hypothesized that the two dance groups would show more gain than the no-dance group with the most gain observed for participants in the cognitively challenging dance class given its combination of mental and physical exercise. Neither of these hypotheses was supported. Both methodological and theoretical explanations for this failure to find training gains are discussed
