Shahid Beheshti University of Medical Sciences The Scientific Journal of Rehabilitation Medicine 2251-8401 11 5 2022 11 22 Physiological and Neurophysiological Effects of Sports Massage on the Athletes’ Performance: A Review Study Physiological and Neurophysiological Effects of Sports Massage on the Athletes’ Performance: A Review Study 680 691 1101337 10.32598/SJRM.11.5.12 FA Hasan Shamsi Department of Physiotherapy, Faculty of Rehabilitation, Shahid Beheshti University of Medical Sciences, Tehran, Iran. 0000-0003-3221-5420 Farshad Okhovatian Department of Physiotherapy, Faculty of Rehabilitation, Shahid Beheshti University of Medical Sciences, Tehran, Iran. 0000-0003-3891-5647 Khosro Khademi Kalantari Department of Physiotherapy, Faculty of Rehabilitation, Shahid Beheshti University of Medical Sciences, Tehran, Iran. 0000-0001-7599-751X Journal Article 2021 01 13 Background and Aims: Massage therapy is widely used by athletes for various reasons such as recovery from fatigue, preventing injury, and relaxation. It is believed that massage improves the performance of the athletes by increasing their blood flow, removing lactic acid, and stimulating the nervous system. This review study aims to investigate the physiological and neurophysiological effects of sports massage on the athletes’ performance, to find out whether the clinical beliefs of sports physiotherapists about the effects of sports massage on sports injuries are supported by scientific evidence or not. Methods: In this review study, a search was conducted in Google Scholar PubMed, and ScienceDirect databases on studies published in English from 1975 to 2020 using the keywords: Sports massage, sports injuries, physiological mechanisms, neurophysiological mechanisms, and performance of athletes. Fifty articles about the effects of sports massage were assessed for eligibility. Finally, 14 clinical trial studies and one case report study were included in the review. Results: Few studies have been conducted on the effect of sports massage on the athletes’ performance. The existing studies are heterogeneous, i.e., they have examined the effect of massage on different factors and reported contradictory results. It seems that the effects of sports massage on the athletes’ performance are more due to its psychological effects rather than its clinical effects. The effects of sports massage on athletes’ performance have not yet been supported by scientific evidence. Conclusion: Many scholars consider that the effects of sports massage are due to increasing blood flow, but there is insufficient scientific evidence. In treatment of tendonitis and muscle strains, there is insufficient evidence that sports massage can reduce pain and accelerate healing. It seems the therapeutic effects of sport massage are more psychological and less physiological.

The olfactory stimuli can activate the brain areas involved in balance activities. This study aims to investigate the effect of balance exercises combined with olfactory stimuli on the balance of patients with stroke. Methods: In this randomized clinical trial, 32 patients with stroke were randomly assigned into groups of balance+olfactory stimulation and balance. The first group performed the balance exercises while wearing a mask containing the lavender essential oil. The second group performed the balance exercises while wearing a mask containing distilled water. Both groups performed the exercises for 20 min at one session. The timed up & go (TUG) test, 10-m walk test with self-selected speed, and Mini-Balance Evaluation Systems Test (Mini-BEST) were used for assessments. The data were analyzed in SPSS software, version 22. P<0.05 was statistically significant. Results: The mean score of 10-m walk test before and after the intervention was significantly different (decreased) in the combined group (P=0.001) and balance group (P<0.001). The mean TUG score before and after the intervention was also significantly different (decreased) in the combined group (P= 0.008) and balance group (P=0.003). The mean score of mini-BEST before and after the intervention was also significantly different (increased) in the combined group (P=0.001) and balance group (P= 0.008). No significant difference was observed in the mean scores of 10-m walk test (P=0.386), TUG test (P=0.720) and mini-BEST (P=0.152) between the two groups before and after the intervention. Conclusion: One session of balance exercise can improve the static and dynamic balances of patients with stroke. Including the olfactory stimulation by the lavender essential oil in the balance exercise program has no significant effect. It is recommended that the effects of long-term use of different olfactory stimuli on the balance of patients with stroke should be investigated in the future studies.

This study aims to examine the morphological differences of these knee extensor muscles between women with and without LPCS. Methods: In this causal-comparative study, 15 women with LPCS aged 18-30 years and 15 women without LPCS as controls participated who were selected by a convenience sampling methhod. For muscle imaging, the anteromedial (VM) and anterolateral (VL) thigh distal ends were scanned by using a two-dimensional digital ultrasound device (SonoSite Co., USA). The muscles’ cross-sectional area at the patellar base was measured in square centimeters and the muscle-fiber pennation angles of these muscles was measured in degree. Independent t-test was used to compare the variables between the two groups. The significance level was set at 0.05. Results: The cross-sectional area of VM in the control group was significantly higher than in the LPCS group (P=0.001), while the cross sectional area of VL was not significantly different between the two groups (P>0.05). The muscle-fiber pennation angle of VM in the LPCS group was significantly lower than in the control group (P=0.016), while the muscle-fiber pennation angles of VL in the LPCS group was significantly higher than in the control group (P=0.021). Conclusion: The morphology of VM and VL in women with LPCS symptoms shows a significant muscle imbalance that can change the patella position from normal to a more lateral position and increase the contact between the lateral facet of the patella and the lateral femoral condyle, resulting in increased pressure on this area and eventually knee pain.Muscle morphology, Cross-sectional area, Muscle-fiber pennation angle, Lateral patellar compression syndrome, Knee extensors Background and Aims: The morphology of knee joint extensor muscles including vastus medialis (VM) and vastus lateralis (VL), is one of the important and effective factors in lateral patellar compression syndrome (LPCS). This study aims to examine the morphological differences of these knee extensor muscles between women with and without LPCS. Methods: In this causal-comparative study, 15 women with LPCS aged 18-30 years and 15 women without LPCS as controls participated who were selected by a convenience sampling methhod. For muscle imaging, the anteromedial (VM) and anterolateral (VL) thigh distal ends were scanned by using a two-dimensional digital ultrasound device (SonoSite Co., USA). The muscles’ cross-sectional area at the patellar base was measured in square centimeters and the muscle-fiber pennation angles of these muscles was measured in degree. Independent t-test was used to compare the variables between the two groups. The significance level was set at 0.05. Results: The cross-sectional area of VM in the control group was significantly higher than in the LPCS group (P=0.001), while the cross sectional area of VL was not significantly different between the two groups (P>0.05). The muscle-fiber pennation angle of VM in the LPCS group was significantly lower than in the control group (P=0.016), while the muscle-fiber pennation angles of VL in the LPCS group was significantly higher than in the control group (P=0.021).

Hand injuries can significantly affect participation in these activities. Therefore, any factors that interferes with the treatment of hand injuries and postoperative recovery such as smoking should be controlled. Smoking cigarettes use is a public health problem worldwide. The present study aims to investigate the relationship between smoking cigarettes and hand function after tendon repair in men. Methods: This cross-sectional study was conducted on 40 men (20 smokers and 20 non-smokers) who had undergone at least 10 sessions of physiotherapy and 10 sessions of occupational therapy one and a half months after tendon surgery. In order to collect the information, a demographical form and the shortened disabilities of the arm, shoulder and hand questionnaire (QuickDASH) were used. The collected data were analyzed in SPSS software, version 22. Results: There was a significant difference in hand function after tendon repair between smokers and non-smokers (P=0.006). There was no significant relationship between the number of cigarette consumed per day and hand function (P=0.3) Conclusion: It seems that there is a significant relationship between smoking and hand function after tendon repair, but there is no significant relationship between the number of cigarettes smoked per day and hand function. Individual counseling to smokers with hand injuries and expressing the possible negative effects of smoking on their hand function can increase the effectiveness of rehabilitation in them.

Aliasghar Norasteh Department of Physiotherapy, Faculty of Medicine, Guilan University of Medical Sciences, Guilan, Iran. 0000-0003-3540-4470 Journal Article 2020 08 11 Background and Aims: The present study aims to compare the effects of two types of hopping and strength-balance exercises on the balance and strength of selected muscles in athletes with chronic ankle instability. Methods: Participants were 30 male athletes with chronic ankle instability, who were selected using a purposive sampling method and randomly divided into two groups of hopping and strength-balance exercise. A questionnaire was used to record demographic characteristics and the information about the history of sports. To measure strength, a dynamometer was used. The Standing stork test and Y balance test were used to measure static and dynamic balances, respectively. Analysis of covariance and the Least Significant Difference post hoc test were used to compare the means. Results: There was a significant difference in the static balance (P<0.001) and the total dynamic balance between the two groups (P<0.001). The strength-balance exercise group in all directions of the Y balance test performed better than the hopping exercise group. Moreover, hip abduction strength (P=0.02) and the inversion (P=0.005) and eversion strengths (P=0.002) of ankle were significantly different between the two groups after training, where the strength-balance group had higher scores. There was no significant difference between the two groups in other factors. Conclusion: Both hopping and strength-balance exercises can be effective in improving the balance and strength of male athletes with chronic ankle instability, where the strength -balance exercise program seems to be more useful due to its comprehensiveness and given that it emphasizes the improvement of balance, proprioception, trunk strength, and lower limb strength, and can have a greater effect on the fast recovery of athletes.

One of the common methods of correcting these malalignments is corrective exercises. So far, different approaches have been used to correct this malalignment. Given the physical distance during epidemics and the lack of participation in correctional programs, it is not known whether distance training approaches can be as effective as face-to-face training. Methods: The present study was semi-experimental with a pre-test and post-test design. In the present study, 60 female employees were selected and assigned to four groups randomly. The first experimental group performed corrective exercises, the second experimental group performed postural reeducation training at home during the same period of the training program, the third group performed combination exercises, and the fourth group was considered as control. Before and after the intervention of the forward head angle, the kyphosis and rounded shoulders of the individuals were measured. One-way analysis of variance and paired t-test were used to analyze the data. Results: All three experimental groups showed a significant difference before and after the intervention on the forward head angle, kyphosis, and rounded shoulder (P˂0.05). The results also showed that the rate of improvement in the combined training group was higher than that of the two training groups. Conclusion: According to the test of research hypotheses on the effectiveness of corrective exercise and postural reeducation training on the upper cross syndrome, probably combined exercises are more effective than independent corrective and postural reeducation training. Therefore, it is recommended to trainers and corrective exercise specialists that correctional exercises not be limited to the clinical environment and they can be combined with postural reeducation training at home to get better results.

Regular exercise is needed to control and delay the negative effects of aging. This study aims to investigate the effect of a combined exercise program on balance and respiratory fitness of active older men. Methods: In this quasi-experimental study, 40 active older men (Mean age= 62±12.74 years) participated who were selected by a convenience sampling method and randomly assigned into control and exercise groups. Their balance and respiratory readiness were measured using a static balance gauge and spirometry test, respectively before and after the intervention. The exercise group participated in combined exercise program (aerobic, resistance, and balance exercises) for eight weeks, three sessions per week, each for 60 minutes. The control group continued to perform their daily activities during this period. Data analysis was performed in SPSS software version 22 using paired t-test and independent t-test. The significance level was set at 0.05. Results: The combined exercise program had a significant effect on improving static balance in both groups (P=0.002), but not on forced vital capacity (P>0.05). Regarding the forced expiratory volume over 1 second, its effect was significant only in the exercise group (P<0.05). Conclusion: It seems that the combined exercise program can improve static balance and respiratory fitness of older men. It is suggested that the older men use this combined exercise program to increase their balance and respiratory fitness.

In athletes, the position of the scapula have a direct effect on their athletic performance due to its relationship with shoulder function. This study aims to investigates the scapulohumeral rhythm, kyphosis and forward shoulder in Iranian Wushu athletes and non-athletes. Methods: This is a quasi-experimental study. Participants were 27 wushu athletes (Age: 23.29±1.72 years, height: 1.72±0.20 m, weight: 69.50±11.50 kg, body mass index: 22.25±3.29 kg/m2) and 27 non-athletes (Age: 25.92±2.85 years, height: 1.75±0.07 m, weight: 69.36±11.73 kg, body mass index: 22.53±3.08 kg/m2) which were selected using a convenience sampling method. The kyphosis angle was assessed with a flexible ruler and the forward shoulder was assessed using the photographic method. The distance of the scapula from the spine was assessed using the lateral scapular slide test. Independent t-test was used to examine the differences between the groups, and Pearson correlation test was used to examine the relationship between the study variables. Statistical analysis was performed in SPSS software, version 24. The significance level was set at 0.05. Results: The angles of kyphosis and forward shoulder had a significant relationship with the distance of the scapula from the spine at 0, 45 and 90 degrees of arm abduction (P≥0.05) such that with increasing kyphosis and forward shoulder angles, the distance increased. In non-athletes, there was a significant difference between the distances of dominant and non-dominant scapula from the spine in 0 degree (P=0.01) and 45 degrees (P=0.02) of arm abduction; in 90 degrees, no significant difference in non-athletes was observed. Results of independent t-test showed a significant difference in kyphosis and forward shoulder angles and in the distance of the scapula from the spine at different degrees of arm abduction between the two groups (P≤0.05), which were greater in athletes than in non-athletes.
