Botanical Supplements

The present investigation evaluated the efficacy of a botanical supplement that delivered a concentrated dose of Echinacea purpurea (8 grams day−1). The participants were 13 apparently healthy, recreationally active college students (VO2 max: 51 mL O2/kg*min). The participants were provided with a 30-day supplementation regime. Data regarding maximum aerobic capacity was collected through pre- and posttesting surrounding the 30-day supplementation regime. The participants were instructed to maintain normal levels of physical activity and exercise during the experimental period. The levels of physical activity and exercise were monitored via the Leisure and Physical Activity Survey. The participants did not report any significant increases in aerobic physical activity or exercise during the supplementation period. Paired samples t-test analysis did not reveal a significant difference in maximum aerobic capacity, t12=0.67, P=.516. Presupplementation maximum aerobic capacity (M=51.0, SD=6.8) was similar to postsupplementation values (M=51.8, SD=6.5). This study suggests that botanical supplements containing a concentrated dose of Echinacea purpurea is not an effective intervention to increase aerobic capacity of recreationally active individuals.

Maximum Aerobic Capacity

This study was intended to investigate the effect of aerobic gymnastic training at the menstrual cycle phase and perceptions of female students of Sport Science Faculty of State University of Padang on maximum aerobic capacity. The research was conducted using repeated factorial design 2 x 3. Aerobic gymnastic training was a treatment given to the menstrual cycle phase as independent variables, perception as the attribute variable, and the maximum aerobic capacity as the dependent variable. 40 students were taken by using purposive sampling technique as the samples from 170 female students enrolled at 2010/2011 academic year. The data of menstrual cycle phase and perception were collected by using questionnaires while the data of maximum aerobic capacity were taken by using MSFT (beep test). The data of maximum aerobic capacity were then analyzed using by inferential statistics ANOVA 2 x 3 two paths .The data analysis and interpretation indicate that: (1) as the whole, there is a significant difference of the effect of aerobic gymnastic training during premenstrual, menstrual, and postmenstrual phases on the maximum aerobic capacity; (2) there is an interaction between the effects of aerobic gymnastic training during the menstrual phases and the perception on maximum aerobic capacity; (3) there is no significant effect of aerobic gymnastic training during premenstrual and menstrual phases of the students whose positive perception on maximum aerobic capacity; (4) there is a significant effect of aerobic gymnastic training during premenstrual and postmenstrual phases of the female students whose positive perception on maximum aerobic capacity; (5) there is no significant effect of aerobic gymnastic training during menstrual and postmenstrual phases of the female students whose positive perception on maximum aerobic capacity; (6) there is a significant effect of aerobic gymnastic training during premenstrual and menstrual phases of the female students whose negative perception on maximum aerobic capacity; (7) there is no significant effect of aerobic gymnastic training during premenstrual and postmenstrual phases of the female students whose positive perception on maximum aerobic capacity; and (8) there is a significant effect of aerobic gymnastic training during menstrual and postmenstrual phases of the female students whose negative perception on maximum aerobic capacity. The findings imply that the lowness of maximum aerobic capacity of the students during menstruation is not mainly due to the menstruation itself but more to the negative perception during on the maximum aerobic capacity. Therefore, the teachers, lecturers, and trainers are expected to provide the female students (at any levels of education) with better explanation on the menstrual cycle phases and their effects on physical activities (sports)

Mean Differences

Eighteen cardiorespiratory parameters were measured in a five-minute bicycle ergometer test applied before and after four hours of resting (control days) or four hours of treadmill walking at 40, 50, and 60% of the maximum aerobic capacity (exercise days) of four volunteer subjects. There was no significant difference between control and exercise days in 16 out of 18 responses when the mean differences between the results obtained in the “before” and “after” tests were compared. The two exceptions were resting and exercise heart rate at 50 and 60% of the maximum aerobic capacity. Consequently, nine parameters showing the largest changes on exercise days were selected for calculation of a cardiorespiratory variance score (CVS). Subjective feeling of fatigue quantitated by the feeling tone checklist of Pearson was significantly correlated with CVS. There was also a significant relationship between work strain and the CVS. These results suggests that the physiological manifestations of fatigue after strenuous work are not reflected in consistent changes of single parameters but rather in the composit deviation of several responses from the control level. Within equal CVS values, deviation of single parameters may vary day by day in the same individual at identical work loads indicative of instability of homeostatic control during fatigue.

Conceptual Change Model

This study contributes to a growing literature that investigates vocational students’ conceptual understanding of electricity by proposing a multidimensional and pragmatic approach to conceptual change. Conceptual change model-based activities were designed in a six-stage conceptual change model and were incorporated into a four-week course. The effectiveness of these activities was measured in terms of changing these students’ misconceptions about simple electric circuits towards scientifically accepted ideas in terms of their revolutionary versus evolutionary nature and the extent of transfer of learning. Transformative mixed methods research design was used consisting mainly of a one-group pre-test post-test design with DIRECT Test 1.2 as a research instrument. Paired samples t-test analysis for 15 students’ test scores indicated that there was a statistically significant difference between students’ pre- and post-test scores. The results of the frequency analysis in both pre- and post-tests show a significant percentage drop in the number of students having the identified misconceptions. The majority of students during post pre-test interviews justified their answers incorrectly, but more than 80% answered correctly in the post post-test interview. Key words: conceptual change, conceptual change model, electric circuits, misconceptions, vocational education.

Background:Rheumatoid Arthritis (RA) is a rheumatic disease that may coexist many symptoms clinically. These clinical symptoms progress in a vicious cycle in many patients. Physical activity and exercise are known to improve many symptoms in RA patients.Objectives:This study was designed to investigate the effects of clinical pilates exercises on fatigue, depression, aerobic capacity, pain, sleep quality and quality of life.Methods:Thirty voluntary RA patients were included in this study. Patients were separated into three groups equally and each group was applied treatment for eight weeks. Clinical pilates exercises were practiced to the first group, aerobic exercises were practiced to the second group and combined training which was a combination of pilates exercises and aerobic exercises was performed to the third group. Fatigue, depression, aerobic capacity, pain, sleep quality and quality of life were evaluated by Fatigue Severity Scale (FSS), Beck Depression Inventory (BDI), Six minute walk test (6MWT), Short- Form McGill Pain Questionnaire (MPQ), Pittsburg Sleep Quality Index (PSQI) and Rheumatoid Arthritis Quality of Life (RAQoL), respectively.Results:According to our results, statistically significant improvements were found for clinical pilates exercises on fatigue, depression, aerobic capacity and quality of life (p<0.05). Improvements in all parameters except from pain were concluded for aerobic exercises and combined training (p<0.05). Also, there was no statistically significant difference among the treatment groups in assessments (p>0.05).Conclusion:Pilates exercises were found effective and safe for RA patients. Clinical pilates training may be as effective as aerobic exercises in patients with RA according to our study. Therefore, addition of clinical pilates exercises to the routine treatment of RA may enhance the success of rehabilitation.References:[1]Hegarty RS, Conner TS, Stebbings S, Treharne GJ.

Summary Study aim: Physical activity is crucial for a child’s development, as well as for the development of the foot. The aim of this study was to assess the correlation of the level of physical activity and physical fitness with the arches of the foot in children in non-weight-bearing and weight-bearing conditions.Material and methods: The study population consisted of 92 children aged 10 to 14 years. We assessed their physical fitness with a modified Zuchora test. The modification consisted in choosing three (speed, jumping ability, and flexibility) out of a total of six trials. To assess the physical activity, we used a screening test - the anonymous Moderate to Vigorous Physical Activity questionnaire. To analyze the arches of the foot, we used computer equipment based on the Moiré projection method.Results: Pearson’s chi-squared test did not reveal any significant correlation between physical activity, physical fitness, and longitudinal and transversal arches in children. The percentage of normal and high foot arches increased with increasing levels of physical activity and physical fitness. A Wilcoxon signed-rank test analysis confirmed a statistically significant difference (with p < 0.001) in the longitudinal and transversal arches in measurements in non-weight-bearing and weight-bearing conditions.Conclusions: 1. In the examined group, there were functional lateral and longitudinal flat feet. 2. A lowered longitudinal arch foot might reduce physical activity and fitness in adolescents.

AbstractBackgroundThe purpose of this study was to examine the level of physical activity (PA) and maximal aerobic capacity (VO2max) among office workers of the Pars Special Economic Energy Zone in Iran with different body mass indexes (BMIs).Materials and methodsThis research was descriptive, and a correlation of variables was applied as its execution method. Administrative staff of two centers were randomly selected from 20 to 30 administrative centers of the Pars Special Economic Energy Zone, Assaluyeh, Iran, and included 294 male employees who were willing to participate in this research and who met the inclusion criteria (being in the age range of 20–60 years, lacking specific diseases, and who had enough physical fitness to do PA) who were purposefully selected.ResultsThe age-adjusted means for the PA score (7.93 ± 1.12) and VO2max(48.66 ± 6.95) mL/min/kg were calculated. After adjusting for other variables, significant difference was found between BMI and age (β = 0.20; p = 0.005), BMI and VO2max(β = 0.302; p = 0.001), as well as BMI and the total PA score (β = −0.304; p = 0.045).ConclusionsThe results of this study showed low levels of PA (work, exercise and leisure) and respiratory capacity in the administrative staff of the oil and gas industry, which is associated with overweight and obesity.

Objective: To determine changes in flexibility, dynamic balance, agility, vertical jump, aerobic capacity, anaerobic capacity, and muscle strength performances in women in the early follicular and midluteal phases of the menstrual cycle. Material and Methods: The study included eumenorrheic women over 18 years of age. Ovulation was detected using LH urine kits. Physical activity levels were determined using the "International Physical Activity Questionnaire-Short Form". Flexibility was evaluated with the sit-and-reach test, dynamic balance with the Y balance test, agility with the hexagon agility test, anaerobic power with the vertical jump test, aerobic capacity with the 20-meter shuttle run test, anaerobic capacity with the Wingate test, and muscle strength with an isokinetic dynamometer. Results: Twenty women participated in the study. The average age was 22.4 ± 0.9 years, and the average level of physical activity was 1162.2 ± 189.1 MET-min/week. The average menstrual cycle was 30.3 ± 0.5 days. The ‘minimum power’ value in Wingate test was higher during the midluteal phase compared with the follicular phase (p=0.048). The remaining parameters were not statistically different for the two menstrual phases (p>0.05). Conclusion: We conclude that different phases of the menstrual cycle affect performance parameters minimally and do not cause a statistically significant difference. Nevertheless, instead of establishing these changes as ‘clinically non-significant’, each athlete should be evaluated on an individual basis to develop individual training programs by taking into account the phases of the menstrual cycle.

Social development requires the removal of barriers so that all citizens can live with confidence and dignity. This development is driven with integrity, to sustain society trust and wellbeing with the help of local enforcement officers. However, local enforcement integrity issues become more serious since they serve public interest and constantly deals with law offenders and public criminals. This study therefore, examines the effects of demographic, experience and organisational factors on the integrity of local enforcement officers. The data was collected in 2017 from Pusat Latihan Penguatkuasa Selangor, a training centre for local enforcement officers in Malaysia. Based on vignettes survey of 216 respondents, a paired-samples t-test analysis was carried out. The results indicate that there is a significant difference between self-proclaim and colleague perception only in the ‘willingness to report’ and not ‘offence seriousness’ category. This study helps local authorities, government, private organisation and the policy makers to ensure integrity issues can be prevented thoroughly in all areas.
