The present study focuses on elucidating the effects of an eight-week combined turning exercise program on the physical performance of female students with Down syndrome (DS), a genetic disorder characterized by intellectual disability and often associated with weaker muscle strength. Individuals with DS typically exhibit reduced muscle strength due to a lower percentage of slow-twitch muscle fibers and a diminished overall number of muscle fibers.

In this semi-experimental clinical trial, the authors used purposive sampling to enroll 26 female students diagnosed with DS. Participants were randomly divided into an experimental group (n=13; mean age: 12.15±1.62 years, mean height: 139.23±8.94 cm, mean weight: 42.62±13.44 kg, mean IQ: 63.02±5.54) and a control group (n=13; mean age: 12.23±1.53 years, mean height: 141.15±10.31 cm, mean weight: 45.46±15.94 kg, mean IQ: 63.05±5.49). The authors evaluated muscle strength using a hand-held digital dynamometer, push-up test, long jump, and sit-up before and after the eight-week training period. The experimental group underwent a combined turning training program lasting 45-60 minutes daily, thrice a week, for eight weeks. We analyzed the data using repeated measures analysis of variance (ANOVA) with a significance level set at p≤0.05.

The findings revealed a significant enhancement in physical performance among participants in the experimental group compared to those in the control group (p≤0.05). Specifically, the combined turning exercise program positively influenced upper body, middle body, and lower body muscle strength in female students diagnosed with DS.

The results of this investigation imply that incorporating combined turning exercises could serve as an effective strategy for enhancing muscle strength among female students diagnosed with DS. Integrating these exercises into rehabilitation programs tailored for individuals with DS may improve their physical performance and enhance their overall quality of life.

Beyond biological changes, ageing is often associated with degenerative and progressive changes in functional and physiological performance. Different types of exercise and rehabilitation method were introduced for resolving or preventing aging complications. The aim of this study was to investigate the effects of 8- week- dynamic neuromuscular stabilization (DNS) training on functional performance and quality of life in healthy elderly men. Twenty-eight old men were selected by convenience sampling manner and divided randomly in two groups of experimental (n=13, age: 65.8±4.3 years, height: 1.63±5.92 cm, weight: 69.1±7.4 kg) and control (n=15, age: 66.3±3.8 years, height: 1.64±4.89 cm, weight: 70.1± 6.3 kg). The experimental group received neuromuscular stabilization training for 8 weeks and 3 sessions for 1 hour in a clinic in Baghdad. Static balance (by functional reach test), dynamic balance (by time-up and go test), functional performance (by Berge test), and quality of life (by Leiden-Padua (LEIPAD e questionnaire) were measured before and after training. Data was analyzed by repeated measure ANOVA in SPSS software. P value was set at P≤0.05. The results showed that the intergroup interaction in the variables of functional performance (F=53.3, P=0.00), quality of life (F=65.04, P=0.00), static (F=106.7, P=0.00) and dynamic (F=26.99, P=0.00) balance was significant with the superiority of the DNS group. Postural control, functional performance and quality of life improved after training protocol. Therefore, DNS training can be used as a complementary method for rehabilitation of elderly.

This study aimed to investigate stance phase characteristics and asymmetry in females with non-specific low back pain (LBPP) which they adopt different strategies in walking to reduce pain and enhance walking quality. The results of this research can provide new insight into gait characteristics for individuals with LBPP by examining temporal characteristics and asymmetry in their stance phase during walking.
In this cross-sectional study, 36 females were purposefully recruited and divided into two groups: one consisting of 18 individuals with low back pain (LBPP) and the other without LBPP. Data were collected using the Footscan system and analyzed with the Footscan Gait 7 gait generation software. Independent t-tests were employed to compare the outcomes between the two groups.
The results indicated that the right (p=0.001) and left (p=0.001) foot progression angles in the low back pain group were higher than those in the healthy group. Additionally, the low back pain group exhibited higher asymmetry in the timings of the initial contact phase (p=0.02) and forefoot contact phase (p=0.02), as well as in foot progression angle asymmetry (p=0.009) compared to the healthy group.
Given the higher foot progression angle and observed asymmetries in individuals with low back pain, rehabilitative exercises need to consider these differences when evaluating and planning rehabilitation procedures.

Aging is related to a decrease in physiological and functional capacity which can increase disability, decrease balance and fall. The widespread problems in the elderly that occur as a result of the aging process are the loss of balance, increase in vertical fluctuations, and the possibility of falling. The purpose of the current study was to investigate the effect of eight weeks of RNT exercises on balance, strength, and quality of life of elderly women.  The statistical population of the present study included 18 elderly women living in Isfahan selected as available sampling and after taking the pre-test, they were randomly divided into two experimental (9 people) and control (9 people) groups. The subjects were trained for 8 weeks and 3 sessions per week for 1 hour at Parsia Clinic. The research tools included functional reach test to measure static balance, timed back and forth test to measure dynamic balance, sit-to-stand test to measure lower limb muscle strength, and Lipad quality of life questionnaire. After the end of the training period, both groups were tested again by SPSS software version 24. The results were analyzed using the ANOVA statistical test for repeated measurements to check the research hypotheses. According to the results, eight weeks of dynamic neuromuscular stability exercises significantly improved the static balance and dynamic balance of elderly women(05/0>p). Also, eight weeks of RNT exercises significantly improved the strength of the lower limb muscles of elderly women and improved the quality of life of elderly women (P<0.05). The present study showed that eight weeks of RNT exercises can be effective in improving static balance, dynamic balance, lower limb muscle strength and quality of life of elderly women. These factors are among the most important factors related to the health of the elderly. Therefore, RNT exercises can be effective for treatment and rehabilitation and are recommended as an effective method to improve these components in elderly women.

Down syndrome is one of the most common genetic diseases in people with intellectual disabilities, which leads to delays in motor skill. Therefore, this study was performed to determine the effect of eight weeks of turning exercises on the motor skills in femaile students with Down syndrome.

In this semi-experimental research, 26 female students with Down syndrome were selected in an accessible and purposeful manner and then divided into experimental group (with an average age of 12.15 ± 1.62, height 139.23 ± 8.94, weight 42.62 ± 13.44 and IQ 63.02 ± 5.54) and control group (with mean age 12.23 ± 1.53, height 141.15 ± 10.31, weight 45.46 ± 15.94 and IQ 63.05 ± 5.49) were randomly paired. Before and after the training period, gross and fine motor skills was evaluated using Short form of Bruininks-Oseretsky test. The subjects of the experimental group underwent 24 sessions (each session lasting 45-60 minutes). Analysis of variance for duplicate data was used to analyze the data at a significance level of 0.05.

The findings revealed a significant interaction in gross motor skills (P < 0.001, F = 113.60), fine motor skills (P = 0.040, F = 4.40) and composite score (P < 0.001, F = 68.56) in the experimental group compared to the control group. These results indicate that the implementation of combined turning exercises had a significant impact on enhancing the motor skills of students with Down syndrome.

According to the results of this study, these exercises can be used as an effective method to improve the gross motor skills of students with Down syndrome.

Inactive lifestyles and neurological disorders among mentally retarded people have caused them to suffer from weaknesses in physical fitness and social adjustment factors. Breathing exercises along with the reconstruction of movement patterns from the first year of life in Dynamic Neuromuscular Stabilization (DNS) exercises, in addition to treatment, can be effective in preventing many disorders. Therefore the present study aims to study the effect of eight weeks of DNS training on respiratory function, functional tests and quality of life (QOL) of educable mentally retarded students.

Twenty-six educable mentally retarded female students with a mean age (17.19 ± 1.50) and IQ (61.15 ± 6.07) were selected semi-experimentally and purposefully based on IQ and two paired into experimental groups (n = 13) and a control (n = 13) randomly. Before and after the training intervention, respiratory function, functional test and QOL variables were assessed through the Rockport walking test, the FMS test and the Cummins questionnaire, respectively. Analysis of variance for duplicate data at a significance level of 0.05 was used to analyze the data.

According to the results of this study, after performing eight weeks of DNS training, there was a significant difference in respiratory function (P = 0.001, F = 82.93), right FMS (P = 0.011, F = 51.00), Left FMS (P = 0.001, F = 46.09) and QOL (P = 0.001 F = 34.25) were created in the experimental group compared to before the training protocol and also in the control group (P < 0.05). Therefore, DNS exercises showed a significant effect on respiratory performance, functional tests, and quality of life of students with intellectual disabilities.

Based on the current results, it appears that DNS exercises can be used as an effective method for improving the breathing performance, functional tests, and quality of life of mentally disabled female students.

Energy Consumption (EC) and Body Mass Index (BMI) are the major complications associated with Spinal Cord Injury (SCI), which can be improved by exercise rehabilitation. Thus, the present study aimed to evaluate the efficiency of using rebound therapy (exercise on a trampoline) on EC and BMI in individuals with SCI.

Sixteen individuals with SCI (ASIA classification: A=6, B=6, C=2, D=2) were selected and randomly divided into two groups of experimental (rebound exercise) and control. The experimental group performed the exercise program by a modified trampoline for 12 weeks (10-30 minutes; 3 sessions a week). EC was measured by the Physiological Cost Index (PCI) and BMI was calculated by standard formula before and after the exercise intervention. Finally, the obtained data were analyzed by Repeated-Measures Analysis of Variance (RM-ANOVA) in SPSS.

The results of RM-ANOVA revealed significant interaction in both criteria (P<0.01). In other words, the experimental group changes were substantial, compared to that of the control group.

The collected results indicated that rebound therapy could, in effect, improve the SCI individuals’ EC and BMI. Furthermore, it was suggested that rebound exercise can be a useful sports rehabilitation method for patients with SCI.
