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
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
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
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
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.

Comparing Executive Functions in Dancers Versus Aerobic Exercisers: A Study on Older Adults
Many older adults may experience cognitive decline with aging, and with a rising aging population it is important to investigate interventions that improve cognitive functions. The purpose of this study was to assess differences in executive functioning between older adult dancers and older adult aerobic exercisers. Given that dance involves the use of executive functions, in addition to engaging in aerobic exercise, older adult dancers were expected to score higher on the executive functioning tasks than the older adult aerobic exercisers. Using the Cambridge Brain Sciences Battery to assess executive functioning, this study sought to compare older adults, 50 years old and above, with 10 or more years of experience in dance or aerobic exercise and a control group with less than or equal to 1 year of experience in these activities. Because no participants were available for the aerobic exercise group, the study simply compared two older adult dancers with six older adults in the control group. A one-way between-groups analysis of variance indicated that the dance group and the control group did not differ significantly on any executive function measures. Specifically, the dance group and the control group did not differ in inhibitory control, planning, or working memory. However, these findings need to be interpreted with caution as the low sample size in both groups resulted in the study to be underpowered. Therefore, it cannot be definitively concluded that dance is not associated with higher cognitive functioning compared to the control group or the aerobic exercise group
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
