To prevent these injuries, individuals at risk should be diagnosed and involved in functional corrective interventions. This study was conducted to investigate the effectiveness of a six-week exercise intervention based on functional training on chest wall mobility, respiratory function, and the quality of functional movement patterns among female bodybuilders. Methods: The current study was a semi-experimental, conducted over six weeks, investigating the effect of a functional training protocol on chest mobility, respiratory function, and functional movement patterns in 40 female volunteers aged 19-39 years. The participants were assigned to two groups, an intervention group (n=20) and a control group (n=20), using a randomization technique. Upper chest mobility (UCM), lower chest mobility (LCM), inspiratory breath-hold time (IBHT), expiratory breath-hold time (EBHT), respiratory rate (RR), functional movement screen (FMS), and closed kinetic chain upper extremity stability test (CKCUEST) were measured at baseline and at the end of the study. Six weeks of functional training (three sessions per week) was implemented. The data were analyzed using repeated-measures analysis of variance (RM-ANOVA) by SPSS software, version 23. Results: A significant improvement was observed only in chest mobility (UCM: 3.74±1.26 vs 8.13±1.26, P<0.001 and LCM: 4.36±1.84 vs 7.63±1.53, P<0.001), CKCUEST (18.42±3.77 vs 21.67±3.23, P<0.01), and overall score of the FMS tests (14.55±1.93 vs 16.65±1.87, P<0.003), and the RR (18.00±3.43 vs 17.00±3.46, P<0.001) in the functional training group. Conclusion: It seems that doing the functional exercises program can improve chest mobility, respiratory function, and the quality of functional movements of female bodybuilders. It is recommended for coaches and athletes to use these exercises along with specific bodybuilding exercises.

Twenty three healthy athletes (7 women, 16 men) and 15 athletes with PFPS (3 women, 12 men) ranging in age from 20 to 30 years took part in the current study. A bi-armed goniometer was used to measure range of motion of knee flexion and extension, and hip flexion, extension, abduction, adduction, internal and external rotation in the groups. No significant differences were demonstrated in range of motion of knee and hip between the patients with PFPS and control group (P>0.05). It may be assumed that athletes with PFPS had no restricted ROM of knee and hip joints in comparison to the control group.

DNS exercises are used to assess and activate the spinal stabilizers to improve the performance of the posture and respiratory systems. Methods: In this semi-experimental study, 60 participants were randomly assigned to two groups as follows: The DNS group (n=30) and the control group (n=30). To start, in a random order, each participant completed a pre-test of the upper chest mobility, lower chest mobility, upright sitting height, and QoL. The DNS protocol was then implemented, with participants undergoing training six times a week for six weeks. After the completion of training, a post-test was conducted to measure all parameters. The data was analyzed using descriptive statistical analysis and repeated measures analysis of variance in the SPSS software, version 23. Results: In the DNS group, significant improvements were observed in the post-test compared to the pre-test for upper chest mobility (2.1±1.6 vs 3.7±1.8 cm, P<0.001), lower chest mobility (2.9±1.4 vs 3.8±1.4 cm, P<0.001), upright sitting height (86.1±3.8 vs 87.7±3.8 cm, P<0.001), and QoL (63.7±17.8 vs 68.2±14.9, P<0.001). On the other hand, the control group did not show statistically significant changes in these parameters. Conclusion: DNS which prioritizes ideal alignment, is an effective protocol for enhancing upper chest mobility, lower chest mobility, upright sitting height, and QoL. It is recommended to incorporate breathing exercises to enhance chest mobility and posture. By doing so, physiological stabilization can be achieved, leading to improvements in the overall health and performance of obese individuals, ultimately enhancing their QoL.

This study aimed to determine whether an aquatic training intervention improves QoL among healthy elderly men. A total of 40 elderly men aged 66–86 years were recruited from the Department of Education Retirees. Participants were randomly assigned in a 1:1 ratio to a 12-week aquatic training regimen (exercise group) or a non-exercise control group. The exercise group performed three 45-min sessions per week. Data were collected using a Survey short form-36 (SF-36) questionnaire before and after the intervention. The aquatic training intervention induced significant improvements in physical (84.6% vs − 1.4%; P < 0.001) and mental (57.1% vs − 11.3%; P < 0.001) health component score in comparison with the control condition. The findings showed that the aquatic training intervention could be an efficient strategy that helps to ameliorate the physical and mental aspects linked to aging and may be an important preventive approach for the future risks in this population.

The effect of different warm-up stretch protocols on 20-m sprint performance in trained rugby union players. J. Strength Cond. Res. 18(4):000-000. 2004.-The purpose of this study was to determine the effect of different static and dynamic stretch protocols on 20-m sprint performance. The 97 male rugby union players were assigned randomly to 4 groups: passive static stretch (PSS; n ϭ 28), active dynamic stretch (ADS; n ϭ 22), active static stretch (ASST; n ϭ 24), and static dynamic stretch (SDS; n ϭ 23). All groups performed a standard 10-minute jog warm-up, followed by two 20-m sprints. The 20-m sprints were then repeated after subjects had performed different stretch protocols. The PSS and ASST groups had a significant increase in sprint time (p Յ 0.05), while the ADS group had a significant decrease in sprint time (p Յ 0.05). The decrease in sprint time, observed in the SDS group, was found to be nonsignificant (p Ն 0.05). The decrease in performance for the 2 static stretch groups was attributed to an increase in the musculotendinous unit (MTU) compliance, leading to a decrease in the MTU ability to store elastic energy in its eccentric phase. The reason why the ADS group improved performance is less clear, but could be linked to the rehearsal of specific movement patterns, which may help increase coordination of subsequent movement. It was concluded that static stretching as part of a warm-up may decrease short sprint performance, whereas active dynamic stretching seems to increase 20-m sprint performance.

But the outcomes of this approach remain unclear. So changes in some spirometry indices in response to DNS breathing exercises in sedentary students with poor posture will be explored. Methods: In this single-group pretest-posttest study design, we involved 26 male volunteer sedentary students with poor posture. First, a pretest of the spirometry indices (Maximum Voluntary Ventilation (MVV), Forced Expiratory Volume in first second (FEV1), Forced Vital Capacity (FVC), and FEV1/FVC ratio) were done each participant in random order. DNS breathing exercise protocol (six times a week, for six weeks) were trained and after completion of training, the post-test of the same parameters was performed. Descriptive statistical and the paired-sample test were used to analyze. Results: The findings of data analysis indicated that the effect of DNS breathing exercise on respiratory function and significant improvements were observed in post-test compared with pre-test in the following parameters: MVV (178.0±21.
