This study examined the effects of rhythmic step aerobics on movement smoothness and core dynamics in middle-aged women, focusing on forward and reverse stepping. While step aerobics enhances balance and musculoskeletal function, its impact on kinematics—especially movement smoothness and synchronization—remains underexplored. This study analysed centre of mass motion using inertial measurement units in three dimensions. Nine middle-aged women (age: 53.38 years, BMI: 24.45 ) completed 24 training sessions, with evaluations every 12 sessions. Step detection was performed using continuous wavelet transform, stance-to-swing ratio assessed temporal adaptation, and jerk cost analysis quantified movement smoothness. Hierarchical clustering (Ward’s method) identified motor adaptation patterns. Results showed significant kinematic adaptations, particularly in backward stepping, with increased stance duration and smoother motion. Notably, the third step (first backward step) reflected adaptation, especially from the 12th to 24th sessions, suggesting the central nervous system prioritized this particular step for initial stability. In contrast, no significant adaptation was observed in the fourth step, indicating asymmetry in lower limb trainability. Alternating the leading step every minute may reduce asymmetry. These findings highlight rhythmic step aerobics as a promising intervention for mobility enhancement, with stance-to-swing ratio and smoothness as valid trainability metrics for prehabilitation and rehabilitation programs.

Improving physical education means and methods among children, adolescents and youth is an urgent and indemand area of activity for specialists in this field. The low rate of improvement in the indicators of physical health of the population, its insufficient motivation for physical activity makes it necessary to search for effective methods of wellness orientation. Research aim. To develop and experimentally substantiate a program for motor qualities and coordination abilities development fitness in 12-14-years-old girls in the process of extracurricular step aerobics classes. Materials and methods. The experimental project was carried out on the basis of a comprehensive school in Chelyabinsk (Russia). There were 30 girls under observation, aged 12-14, who had no medical restrictions on physical activity. The girls were divided into two groups: control (CG, n=15) and experimental (EG, n=15). As part of additional physical education in school conditions, girls of both groups studied three times a week for 45 minutes according to the general education program «General physical training». The program used complexes of general developmental physical exercises to develop the students basic motor qualities and coordination abilities. The educational process for the EG girls followed our developed program. EG girls engaged in a traditional general educational curriculum twice a week, while incorporating special aerobic exercise complexes using a step platform once a week. Rigorous testing was conducted to assess the level of general physical fitness and coordination abilities. Results. Upon project completion, it was evident that EG girls exhibited significantly higher values in almost all motor and coordination tests, along with notable growth rates than the CG girls. At the end of the project, 60.0% of girls were classified as «high» in terms of motor skills and 53.3% in coordination skills, which is significantly more than in CG. A positive vector for the motivation to engage in wellness fitness development has been established not only among EG girls, but also among their classmates. Conclusions. The proposed program for the general physical fitness and coordination skills development has shown its effectiveness. It can be used in regular and additional physical training of students, studying at educational institutions.

Step-aerobic training (SAT) has been effective exercise pattern on balance. Very few studies focused on female badminton players. Objective: was to compare the effects of SAT on balance in female badminton players. Methods: twenty female participants were divided into the experimental group (EG), practiced a step aerobics tempo using a speed controller at a speed range of 125-140 beats per minute (bpm) and height of 4, 6, and 8 inches practice for 30 minutes 3 days a week, together with the 8 week badminton training program (n=10, age: 16.70±1.15 years; body weight = 54.19±2.86 kg; body height = 164.10±3.66 cm; fat = 23.32±2.07 percent; muscle mass = 41.47±2.24 kg). The control group (CG) performs the badminton program training. (n = 10, age: 16.60±1.17 years; body weight = 53.98±3.09 kg; body height = 164.20±3.32 cm; fat = 23.52±2.36 percent; muscle mass  Conclusion: the SAT at 6 - 8 inches in height using 125 - 140 bpm has a beneficial effect on balance, which allows athletes to be more efficient in moving quickly in a short training period without losing balance.  

Background: Step-aerobics training is one of the most exercise popular which is safe, a low-impact form of exercise, and does not cause any impact on the knee and ankle joints, it is ideal for developing the power of muscle and agility in a change of direction, that is essential for athletes. Objective: This study was to examine muscle power and agility following step-aerobic training in male badminton players. Methods: The study was an experimental research design conducted on a study recruited twenty male badminton players (aged 19-22) who were randomly divided into two groups. The subjects were initially tested for muscle power by a vertical jump and agility test. Thereafter, the experimental group underwent step-aerobic training for 30 minutes three days a week for eight weeks, and the control group continued its badminton training routine without step-aerobic training. After eight weeks, the study tested all groups for muscle power and agility. Result: A group x time interaction for the muscle power of the experimental group after four weeks (p 0.003) and eight weeks (p 0.001) increased than before and after eight weeks (p 0.001) was significantly increased than the control group. The agility time of the experimental group after step-aerobic training for four weeks (p 0.001) and eight weeks (p 0.001) decreased than before and after eight weeks (p 0.002) was significantly decreased than the control group. Conclusion: This study showed that the step-aerobic training pattern in increasing the rhythm movement of 125-140 beats per minute and the 6-8 inches height of step-aerobic can help badminton players enhance their muscle power and agility in four weeks.

The article is devoted to the search of the new, modern and effective methods for conducting the physical education classes for the students. The effectiveness of these methods is determined by an increase in the level of the development of the basic physical qualities and an increase in the volume of the motor activity of those who are engaged in it. The possibility of using the Kangoo Jumps exercise complexes on the physical education classes with the female students with an experience in aerobic exercise is considered. In the course of the studies a significant (P <0.05) increase in the rates of the girls' development of speed and endurance using Kangoo Jumps was found. The indices of the development of the muscle strength and flexibility in the experimental and control girls' groups increased slightly. The average body weight of the girls under study did not undergo significant changes during the study. You can recommend Kangoo Jumps exercises for the physical activity to people who have experience in step aerobics.

Suzan Sayegh, Mercia Van Der Walt, Mohamed Ghaith Al-Kuwari Exercise is Medicine Department, Aspetar Orthopedic and Sports Medicine Hospital, Doha, Qatar Background: Physical inactivity is a growing health concern and has been identified as the fourth leading risk factor for global mortality. The Arab region includes countries with some of the world's highest physical inactivity levels, such as Qatar, more specifically the Qatari female population.Objective: The objective of this study is to assess the physical activity levels of Qatari national female adults during a 1-year pedometer-based program.Materials and methods: A total of 549 Qatari national females aged between 18years and 64years were included. Data extracted from \"Step into Health\" program web database in Qatar were used for analyses. Daily habitual physical activity (daily total step count and aerobic steps) was assessed through the Omron HJ-324U pedometer. Step counts were classified as follows:<5,000 steps/d, sedentary; 5,000-7,499 steps/d, low active; and ≥7,500 steps/d, physically active. Statistical significance was set at P-value ≤0.05. Descriptive statistics were used, and habitual physical activity was calculated through repeated measures analysis of variance to determine the difference across the monitored days.Results: Mean age was 37.4±11.7years, and median body mass index of 28.8 kg/m2 (interquartile range 24.8-33.5). Daily steps for the overall population ranged from 3,505 steps/d to 10,010 steps/d, with a median of 6,008 steps/d. A total of 242 (44.1%) females were sedentary, 178 (32.4%) were low active, and 129 (23.5%) were physically active. The physically active group showed a median of 927aerobic steps/d (interquartile range 0-4,248).Conclusion: Based on the results of this study, Qatari females are not meeting the global recommendations of physical activity. Future research might need to consider barriers to physical activity as well as social, cultural, and environmental factors. Keywords: aerobic steps, daily steps, step count, community-based program

The objectives of this study were to compare the energy expenditure and heart rate responses between three commercial group fitness classes (group resistance exercise [PUMP]; indoor stationary cycling [RIDE]; and step aerobics [STEP]). One-Way Repeated Measures incorporating a Latin Square Design for class randomisation. Ten participants (5 males and 5 females) completed each group fitness class in random order with energy expenditure and heart rate determined using an Actiheart monitor. STEP and RIDE produced significantly (p<0.05) higher average heart rates (HRavg) (85.8±5.1% and 86.4±4.3% of HRmax, respectively) compared to PUMP (73.7±7% of HRmax). HRpeak was also significantly (p<0.05) higher in STEP and RIDE (97.1±4.7% and 95.6±4.5% of HRmax, respectively) when compared with the PUMP class (90±5.9% of HRmax). Total energy expenditure (TEE), both absolute and relative, were significantly (p<0.05) higher for STEP (2101.7±560.2kJ and 0.59±0.07kJkg−1min−1) and RIDE (1880.4±420kJ and 0.58±0.03kJkg−1min−1) when compared with the PUMP class (1385.1±504kJ and 0.36±0.07kJkg−1min−1). These data suggest that overall exercise intensity and energy expenditure was highly comparable between RIDE and STEP, which suggests these group fitness classes are more effective for developing cardiovascular fitness and assisting with weight management compared with group resistance exercise classes when performed on a regular basis.
