Rosemary Essential Oil

Muscle soreness is a problem associated with physical activities. Recently, the medicinal herbs are strategies to prevent muscle soreness. The present study aims were to determine the effect of rosemary essential oil on the responses of lactate dehydrogenase, creatine kinase (CK), lymphocytes, neutrophils, muscle swelling (MS) and muscle pain (MP) following eccentric leg curl exercise in non-active women. 24 non-active females voluntarily participated in this study and were randomly assigned into three groups: rosemary dose 1 (RD1) (n=8; 0.25 ml), rosemary dose 2 (RD2) (n=8; 0.5 ml) and placebo (n=8; 0.5 ml olive oil). Participants in supplement groups consumed the desire amounts of rosemary essential oil every 8 h per day for 14 days. Then, the eccentric leg curl exercise was performed. The supplementation continued until 72 h after exercise. The serum variables, as well as, MS and MP were measured before, 24, 48 and 72 h after exercise. Data were analysed using repeated measure analysis of variance and P≤0.05 considered as significant. The results showed that rosemary significantly decreases CK in RD2 compared with placebo and RD1 48 h after exercise. There was no other significant difference in other serum variables. In conclusion, the present study showed a beneficial effect of rosemary on 48-h post-exercise serum CK concentration (a muscle damage indicator).

The design of this study is a quasi-experimental. The sample used in this study was eight respondents with certain criteria. Treat physical activity twice on different days with 4 measurements of uric acid levels. The method of this study is repeated measure analysis. When subjects are measured repeatedly, requiring fewer subjects per experiment, then repeated measures analysis can be used. The results showed that the treatment of badminton had a significant effect on changes in uric acid levels with a probability value of 0,038. These results were obtained by using the Greenhouse-Geisser test where the assumptions of normality and homogeneity were satisfied. From the marginal test results using pairwise comparisons, there was a significant difference in the average uric acid levels at 15 minutes after exercise and 9 hours the following day, where there was a decrease of 1.169 mg/dl. Badminton can reduce uric acid levels, which is indicated by a decrease of 0.15 mg/dl at 09.00 the next day compared to before exercise. Marginally, this decrease is not statistically significant, but regular badminton can be an option for physical activity for those who want to reduce uric acid levels.

Abstract The present study investigated the acute effect of eccentric exercise on blood plasma actin, gelsolin (GSN) and orosomucoid (AGP) levels in untrained and moderately trained individuals, and their correlation with exercise induced muscle damage (EIMD) markers (CK, intensity of muscle soreness and maximal voluntary contraction torque deficit). Healthy physical education students (6 untrained, 12 moderately trained) participated in this research. Actin, GSN, AGP and CK levels were measured in blood plasma at baseline, immediately, 1 h, 6 h and 24 h post-exercise comprising 90 eccentric quadriceps contractions performed on a dynamometer. There was significant time main effect for GSN, AGP, CK and significant difference was found between baseline and the lowest value of post-exercise GSN (p < 0.05), as well as baseline and the highest value of post-exercise AGP (p < 0.05). Relationships were found between GSN levels and other indirect EIMD markers (between all GSN levels at post-exercise and CK activity at 6 h, p < 0.05; GSNMIN and muscle soreness at post-exercise, p < 0.04), GSN and AGP; however, actin did not correlate at any time points with GSN. Actin, GSN, AGP and CK responses after eccentric exercise do not seem sensitive to training status. The plasma actin level is used as an indicator of injury, however, our results suggest that it is not an accurate marker of EIMD, while plasma GSN concentrations show a better relationship with EIMD and the post-exercise inflammatory process. The elevated plasma AGP and the correlation between GSN and AGP seem to be promising for assessment of exercise-induced muscle injury.

Platelets are a primary source of pro- and anti-angiogenic cytokines. However, the evidence of their role in retinopathy of prematurity (ROP) is controversial. This retrospective study aimed to compare mean weekly platelet counts between infants with and without ROP over the first 6 weeks of life. A total of 93 infants matched by gestational age and birth weight were recruited (31 with ROP, 62 without ROP). Weekly mean platelet counts and other related risk factors were documented. The repeated measure analysis of variance (ANOVA) and the repeated measure analysis of covariance (ANCOVA) were used to compare mean platelet counts over time between the two groups, with and without adjusting for confounders. We found significant differences in the weekly mean platelet counts of infants with and without ROP over the first 6 weeks of life (p = 0.002). These differences disappeared after adjusting for covariates (p = 0.489). Lower mean platelet counts in ROP infants are not directly related to ROP, but rather to the presence of other risk factors for ROP, such as culture-proven sepsis, blood transfusion and bronchopulmonary dysplasia.

Background: In military environment, soldiers regularly practice or undergo different types of extreme training activities. However, globally the literatures available on the physiological and biochemical demand of different extreme military training activities are very scanty and less reported. Aims and Objective: The present study was undertaken to quantify the cardio-respiratory and biochemical responses of military training event in jungle environment. Materials and Methods: Mathew’s Mad Mile (MMM) activity is a type of specialized run of 1.5 mile in jungle environment. This training activity was conducted on rugged jungle terrain comprised of undulated uphill, downhill, muddy surface. Twenty-five SHAPE-1 healthy soldiers were volunteered into training event. Cardiorespiratory data was recorded continuously throughout the event and venous blood sample was drawn before and immediately after completion of the event. Statistical significance was considered at p<0.05. Results: There was no significant difference observed in heart rate and breathing rate while core body temperature was significantly (p = 0.02) higher in slow finisher as compared to fast finisher. In fast finisher, post exercise level of BDNF, BNP, SDH, cortisol and UCP1 increased significantly (p<0.05), whereas, BHB (p<0.01) decreased significantly in comparison to pre-exercise. In slow finishers, post exercise level of cortisol, KYNA and UCP1 increased significantly (p<0.05), whereas, BDNF, BNP and SDH decreased significantly (p<0.05), in comparison to pre-exercise. Conclusion: The outcome of this study indicated that the slow finishers were more susceptible to risk of injury due to higher exercise induced thermogenesis and mental stress in comparison to fast finisher.

Summary Background In orthodontic trials, longitudinal designs with multiple outcome measurements over time are common. The aim of this epidemiological study was to examine whether optimal statistical analysis approaches have been used in longitudinal orthodontic trials. Methods Pubmed was searched in August 2021 for longitudinal orthodontic trials with at least three time points of outcome assessment published in the 2017–20 period. Study selection and data extraction were done independently and in duplicate. The analysis approaches undertaken were tabulated and associations between study characteristics and the use of optimal analysis or not were assessed using Fisher’s exact test and logistic regression. Results One hundred forty-seven out of 563 unique records were deemed eligible for inclusion. Only 26.50% of these trials used an optimal statistical analysis for longitudinal data where the data structure is accounted for. None of the study characteristics except the statistical significance of the results were associated with the appropriateness of the statistical analysis. The odds of significant results in studies with suboptimal analyses were higher than that in studies with optimal longitudinal analyses (odds ratio: 3.48, 95% confidence interval: 1.62, 7.46, P = 0.001). For the studies with optimal analysis, the most frequent test was repeated-measure analysis of variance (RM-ANOVA). The reporting of the statistical analysis section was suboptimal in the majority of the trials. Conclusion Most longitudinal orthodontic trials are not analysed using optimal statistical approaches. Inferences and interpretation of their results are likely to be compromised.

The present study examined if the magnitude of changes in indirect muscle damage markers could be predicted by maximal voluntary isometric contraction (MVIC) torque changes from immediately to 1 day after eccentric exercise. Twenty-eight young men performed 100 maximal isokinetic (60°/s) eccentric contractions of the knee extensors. MVIC torque, potentiated doublet torque, voluntary activation (VA) during MVIC, shear modulus of rectus femoris (RF), vastus medialis and lateralis, and muscle soreness of these muscles were measured before, immediately after, and 1–3 days post-exercise. Based on the recovery rate of the MVIC torque from immediately to 1-day post-exercise, the participants were placed to a recovery group that showed an increase in the MVIC torque (11.3–79.9%, n = 15) or a no-recovery group that showed no recovery (−71.9 to 0%, n = 13). No significant difference in MVIC torque decrease immediately post-exercise was found between the recovery (−33 ± 12%) and no-recovery (−32 ± 9%) groups. At 1–3 days, changes in MVIC torque (−40 to −26% vs. −22 to −12%), potentiated doublet torque (−37 to −22% vs. −20 to −9%), and proximal RF shear modulus (29–34% vs. 8–15%) were greater (p &lt; 0.05) for the no-recovery than recovery group. No significant group differences were found for muscle soreness. The recovery rate of MVIC torque was correlated (p &lt; 0.05) with the change in MVIC torque from baseline to 2 (r = 0.624) or 3 days post-exercise (r = 0.526), or peak change in potentiated doublet torque at 1–3 days post-exercise from baseline (r = 0.691), but not correlated with the changes in other dependent variables. These results suggest that the recovery rate of MVIC torque predicts changes in neuromuscular function but not muscle soreness and stiffness following eccentric exercise of the knee extensors.

Background and Purpose: Recently raised questions on adaptability of native tree species to climate changes pointed to Douglas-fir as a species suitable for rapid reforestation and increase of stand resistance. The first results on provenance research need to be confirmed in later stages of stand development, so the paper answers the following two questions: (i) are there differences in growth of 14 Douglas-fir provenances still in the fifth decade of stand development, and (ii) which provenances should be used and which omitted from further use in the hilly area of Croatia? Materials and Methods: Productivity of 14 provenances was evaluated on the basis of height, diameter at breast height and volume in the 46th year after planting. Growth dynamics was also statistically analysed using a repeated measure analysis of variance, for which purpose we partially used published data from the 2010. Results: The analysis excluded Castle Rock and Shady Cove (Oregon) provenances due to their low values of all analysed growth indicators, as well as Castle Rock, Elma and Hvidilde provenances due to their high values. Average values of tree volume ranged from 0.53 m3 (Shady Cove) to 2.05 m3 (Castle Rock), while the tallest trees belonged to Elma provenance (29.6 m). Conclusions: Different growth dynamics of provenances were confirmed for later development stage, so further monitoring is still required. Clear guidelines for the selection of provenances for practical forestry distinguish provenances from lower altitudes of the State of Washington, Denmark and Bulgaria as the most productive. Shady Cove and Salmon Arm provenances are not advised to be used in the future.

A family counseling intervention grounded in systemic family therapy was conducted in a Title I school-based setting with ( N = 48) kindergarten through sixth-grade student-clients and their primary caregivers. Families’ perception of family communication and satisfaction on the Family Adaptability and Cohesion Evaluation Scale-IV was investigated to determine changes in the percentile score at three benchmarks. A repeated measure analysis of variance indicated a statistically significant difference over time in caregivers’ perception of family communication and satisfaction after 5 and 10 weeks. There was no difference in relationship to gender. School-based family counseling programs can contribute to improved family communication and satisfaction. School-based counselors can partner with institutions of higher education to provide free and accessible counseling for students and families in the greatest need.
