Background and Study Aim: Sport exercises play a major role in many hormonal factors which related to happiness in human. Therefore, the short-term effects of three anaerobic, aerobic and resistance exercises on (BDNF) and hormones related to happiness such as serotonin and beta-endorphin has been studied in young men in this research. Materials and Methods: Thirty-two students (19 to 25 years old) who did not have regular physical activity were randomly divided into four groups, after the subjects were eaten the same breakfast, the blood of them were taken before and after the various short aerobic exercises (Exhaustive exercise with 70% of maximum heart rate) and anaerobic (Exhaustive exercise with maximum intensity) and exhaustive resistance exercise (with 8 stations). Control group did not practice any activity. Specific kits and ELISA method have been used to determine their values. Data were analyzed using ANOVAand ANCOVA method at a significant level of 5%. Results: Beta-endorphins showed a significant increase in resistance and aerobic training sessions compared to control group. However, serotonin and BDNF had a significant intra-group change in the aerobic group. Conclusion: It seems that aerobic exercises are the best practice for increasing some of the hormones associated with happiness.

Resistance Exercises

Combined exercise training (CT) including aerobic plus resistance exercises could be more effective in comparison with aerobic exercise (AT) alone in reducing blood pressure variability (BPV) in hypertensive patients. We report that CT was indeed more effective than AT in reducing short-term BPV, and both exercise modalities reduced BP levels to the same extent. CT appears to be a more appropriate exercise modality if the objective is to reduce BPV in addition to BP levels.

AbstractPrior research about the effects of the amount of exercised muscle mass upon cardiovascular responses (CVR) has neglected a potential bias related to total exercise and concentric/eccentric duration. Autonomic responses and perceived exertion (RPE) were compared in resistance exercises performed with larger and smaller muscle mass and matched for total exercise and concentric/eccentric duration. Twelve men performed 4 sets of 12 repetitions of unilateral (UNI) and bilateral (BIL) knee extensions at 70% of 12RM. Increases in CVR were always greater at the last set of BIL over UNI, as were SBP (35% vs. 23%), DBP (36% vs. 23%), HR (40% vs. 26%), RRP (90% vs 53%) and CO (55% vs 39%). No difference between protocols was found for autonomic modulation before and after exercise, but BIL induced significantly greater changes than UNI from baseline for R-R intervals (−13% vs. −7%), SDNN (−38% vs. −17%) and rMSSD (−41% vs. −21%). The rate of perceived exertion in the last set was higher in BIL than UNI (7.6±0.5 vs. 6.6±1.4 OMNI-RES; P<0.05) and did not correlate with any CVR. Thus, CVR were greater in resistance exercise performed with larger than smaller muscle mass. This information is relevant for patients with high cardiovascular risk.

Abstract Introduction Pectus carinatum (PC) is a congenital chest wall deformity which is characterized by the protrusion of the sternum and costal cartilages. Although orthotic and exercise therapies are commonly offered by physicians for PC treatment, there is a lack of evidence on the benefits of exercises and how long the orthosis should be worn. The aim of this study is to investigate the effects and feasibility of custom-made compression orthosis and exercises in the treatment of PC. Materials and Methods Patients with PC aged 7 to 17 years old were randomized into three groups: compression orthosis 23 hours, compression orthosis 8 hours, and control group. All groups received exercises for 1 hour a day for 3 weeks. Additionally, compression orthosis 23 hours group wore the orthosis for 23 hours a day, while compression orthosis 8 hours group wore the orthosis for 8 hours a day. PC protrusion, pressure of correction, thorax lateral and anteroposterior parameters, external chest wall measurements, and Nuss Questionnaire were evaluated before and after the treatment. Also, adverse effects, retention, and compliance were assessed. Feasibility was evaluated by calculating the percentages of recruitment, retention, and safety. Results The compression orthosis 23 hours group showed greater improvements than the other groups. After treatment, all groups showed significant changes in protrusion, pressure of correction, and external chest wall measurements. Adverse events occurred with similar frequency across groups. Retention percentages did not differ among groups. Conclusion Compression orthosis use for 23 hours can be recommended rather than its use for 8 hours because 23 hours of orthosis use has better correction and similar adverse effects.

Background: Osteoarthritis is the most common joint disease (arthropathy) and a cause of disability in aging ages. The prevalence rate of the osteoarthritis is different and is related to different indicators. Objectives: The purpose of the present study was to investigate the effect of eight weeks of hand-selected exercises and cinnamon supplementation on inflammatory biomarkers in elderly women with osteoarthritis. Methods: The participants of this study were 48 women with hand-osteoarthritis. They divided into four groups (strength exercises, cinnamon-honey supplementation, combinatory and control) randomly. The first group underwent the hand-selected strength exercises. The second group used the supplementations for 8 weeks. The third group also applied hand-selected exercises and supplements simultaneously. The fourth group also participated as a control group without any exercise or supplementation. Patients’ TNfα and IL6 levels were measured before and after applying the independent variables and were compared. The dependent t-test was used to compare between pre and posttest and the ANOVA test to compare TNfα and IL6 levels between the four groups. The significance level P ≤ 0.05 was considered. Results: The results showed that by applying variables, the strength exercises and cinnamon-honey supplementary as well as the combination of exercises and supplementary have had a positive effect on inflammatory biomarkers and in fact, 8 weeks of resistance exercises and using cinnamon-honey supplements in women with hand osteoarthritis have led to a decrease in IL 6 and TNfα levels. Conclusions: Therefore, it is recommended to use wrist resistance exercises with supplements (cinnamon and honey) to accelerate the recovery of the disease and improve the wrist inflammatory.

Background: The use of HMB supplement is prevalence among athletes to reduce proteolysis and increase muscle mass. Therefore, the purpose of this study was to investigate the effect of short-term beta-hydroxy-beta-methylbutyrate (HMB) supplementation on serum cortisol and testosterone levels in wrestling men following an exhaustive exercise. Methods: Sixteen male wrestlers were randomly divided into two groups including: HMB supplementation (40 mg/kg body weight; n=8) and placebo (n=8). Both groups, after two weeks of supplementation, performed an exhaustive exercise. Blood was obtained before supplementation (Base), before exhaustive exercise, immediately after exhaustive exercise, one hour and 24 hours’ after exhaustive exercise. Circulating concentrations of cortisol and testosterone were assayed. Results: The results of this study indicated that there was no significant difference between the two groups at serum cortisol levels of resting state (before exhaustive exercise) and after exhaustive exercise (immediately, one hour and 24 hours later) (p<0.05). However, there was significant difference between the HMB and placebo groups at serum testosterone levels and testosterone/cortisol of resting state (before exhaustive exercise) and after exhaustive exercise (p<0.05). Conclusion: In general, short-term beta-hydroxy beta-methyl butyrate (HMB) supplementation does not affect the serum cortisol in male wrestlers before and after an exhausting exercise. However, HMB supplementation can lead to a significant increase in serum testosterone and T/C before and after an exhausting exercise.

Objective: Ventilation attenuation often happened in professional divers due to long-term cumulative effects in diving exercises. By case-control experiments, we observed the immediate effects of pulmonary ventilation before and after the exposure of 12m-depth underwater for 20 min to discuss the relationships between the short-term and long-time effects caused by diving environment. Methods: Participants were randomly assigned into the Experimental Group (EG) who stayed for 20 min under 12-m water environment or the Control Group (CG) who stayed in hyperbaric chamber under the pressure of 2.2ATA. Pulmonary ventilation function parameters including VC, FVC, MVV and MV were detected respectively before and after hyperbaric exposure by the Spirometer. Immediate effects of pulmonary ventilation before and after diving were compared by paired t test to reveal the different influence caused by environmental pressure. Results: The value of VC appears to rise while the MV, MVV were detected decreased after the exposure of 2.2ATA of environment pressure for 20min in the two groups. VC increased more significantly in the CG (t=-1.26, p=0.23) after hyperbaric exposure, that leads to the FEV1.0%t (=FEV1.0/VC %) increase in EG (t=-0.73, p=0.48) while decrease in CG (t=0.42, p=0.17). The same trend in VC, MV and MVV after high pressure exposure in the two groups mainly due to the effect of common factors –the pressure. In addition to the impact of the pressure itself, EG members also face diving related immersion effect, influence of diving equipment load and water under low temperature. The FVC is detected decreased in EG (t=1.21, P =0.25) while it increased in CG (t=-0.42, P =0.68) , but the differences are not significant and couldn’t affect the measured FEV1.0% (=FEV1.0/FVC %) values showed both increasing in EG (t=-1.48, P =0.16) and in CG (t=-0.23, P =0.82). The expiratory flow rate including PEF, FEF25-75, MEF75, MEF50 increased in EG (t are -0.72, -0.69, -0.87 and -0.36 respectively with P all greater than 0.05) while decreased in CG (t are 1.67, 0.50, 1.53 and 0.71 respectively with P all greater than 0.05). MEF25 is the expiratory flow index of not affected by respiratory muscle force and the measured values of MEF25 increased in the EG (t=-0.68, P =0.51) and in the CG (t=-0.36, P =0.72). Conclusion: Water immersion and water temperature during diving exposure could cause and accelerate hemodynamic changes in pulmonary circulation induced pulmonary interstitial edema and led to the increase of external respiratory work. Instant effects of diving exposure in the study are quite consistent with the long-term cumulative effect of professional divers in previous research, which is FVC reduced because small airway become narrower. The results illustrate even the small depth of short-range diving exercise have definite influences on pulmonary ventilation, which mainly comes from the environmental factor but not the pressure increases.

This study researched whether pertaining to a global strategic alliance brought significant benefits to the ‘bottom line’ of allied airlines. The study used two groups: a group of airlines which had joined one of three global alliances against a control group of airlines which had not joined any alliances. The research compared the net return of those two groups before and after airlines joined their alliances (or equivalent measure), as well as their relative net performance both in the short-term and in a longer term. Results showed a sensible deterioration in net profitability for the alliance group and a perceptible improvement in net profitability for the nonalliance group. The latter also differed from the former in having a positive relative net performance in the short-term.

AbstractRecently, it has been reported that tear osmolarity (Tosm) is correlated with plasma osmolarity and will increase during exertion. We aimed to assess whether inhaling oxygen-enriched air between exercises could significantly change the Tosm value. Thirty men aged 24.9 years were included in the study. A cycloergometer was used to perform the exercise protocol. We recorded the participants’ Tosm (mOsm/L), heart rate (HR, beats/minute), oxygen saturation, and blood pressure values. After the first exhaustive exercise (T1), participants inhaled oxygen in the experimental group and a placebo in the control group. After the second exercise (T2), another set of measurements was obtained. The Tosm value before exercise was 297.4 ± 1.21 and 296.53 ± 1.11 mOsm/L (p = 0.61718) and the HR was 72.6 ± 2.59 and 73 ± 2.59 beats/minute (p = 0.39949) in the study and the control group, respectively. At T1, Tosm was 303.67 ± 1.25 and 302.2 ± 1.25 mOsm/L (p = 0.41286) and the HR reached 178.04 ± 2.60 and 176.4 ± 2.60 beats/minute (p = 0.65832), respectively. At T2, Tosm in the study group reached 305.73 ± 0.86 mOsm/L (correlation with the use of oxygen: r = −0.3818), and in the control group, it was 308.4 ± 0.86 mOsm/L (p = 0.0373), while the HR reached 172.20 ± 2.53 beats/minute in the study group and 178.2 ± 2.53 beats/minute in the control group (p = 0.057). It was concluded that inhaling oxygen before and after exercise could increase the rate of recovery after exhaustive exercise.

This study investigated the short-term effects of a workshop for 22 immediate supervisors designed to reduce musculoskeletal pain injuries. One group of supervisors received training on how to deal with musculoskeletal injuries, while the control group of 14 received no training. 36 male immediate supervisors and 171 male employees within the Swedish railroad system completed questionnaires before and after the intervention. The trained supervisors' ratings showed that they enjoyed the workshop and believed that it improved their skills. Moreover, trained supervisors significantly more often than the controls showed target behaviors and attitudes compatible with course content. Finally, employees of the trained supervisors reported significantly more often than the control group that their supervisor used target behaviors. It is concluded that an educational program for immediate supervisors is viable and may lead to changes in attitude and behavior. Teaching supervisors to work with employees is a rich field for future investigation; the long-term effects of such programs need to be studied.
