Abstract: Excessive body heat while doing physical exercise will be excreted by sweating. Potassium is one of the electrolyte compounds incorporated and washed away together with sweat. In turn, the excessive lost of potassium in sweat can decrease the concentration of extracellular potassium level. Physical exercise can also lead to an increase in serum potassium concentration. The present study was aimed to determine the differences of potassium level before and after physical exercise at moderate intensity at students year 2010 Faculty of Medicine Sam Ratulangi University. Thirty students (27 men and 3 women) were involved in the present pre-experimental study designed with pretest-posttest. Samples were colected using purposive sampling method and analyzed further using wilcoxon test. Data was collected by determine the serum potassium levels before and after moderate intensity physical exercise. Exercise is done in the form of fast walking on a treadmill to maintain heart rate target 64-76 % of maximum heart rate (200 - age) for 30 minutes. The result showed that the average of serum potassium levels before moderate intensity exercise was 4,253±0,3683 mEq/L, and the average of serum potassium levels after moderate intensity exercise was 4,363±0,3908 mEq/L. Wilcoxon test significance values ​​in this study were p=0.110  (p>0,05). It can be concluded that there was no difference of potassium level before and after physical exercise at moderate intensity at students year 2010 Faculty of Medicine Sam Ratulangi University.

Abstract: Sweat losses during exercise that is not balanced by adequate fluid intake can lead to increased concentrations of electrolytes, including sodium in the extracellular fluid. Excessive sweating can also cause loss of electrolytes, particularly sodium and chloride. Excessive sodium loss in sweat may cause a decrease in the concentration of sodium in the extracellular fluid. This study aimed to determine the differences of serum sodium levels before and after moderate intensity exercise in the students of the Faculty of Medicine, Sam Ratulangi University. This study was a pre-experimental with one group pre-post test design. Thirty respondents did brisk walking on the treadmill to maintain target heart rate 64-76% of maximum heart rate (200-age) for 30 minutes. The results showed that the average of serum sodium levels before moderate intensity exercise was 142,37±1,771 mEq/L, while after moderate intensity exercise was 143,07±1,639.

Abstract: Physical exercise stimulates sweat from inside the body to transfer the heat out of it. Sweat consists of both water and electrolytes, including chloride ion, so if the excretion of water and electrolytes is not corrected can disturb the body’s homeostasis and health. This study aimed to determine the differencesof serum chloride levels before and after light intensity physical exercise. This study was a pre - experimental with one group pretest – posttest design. There were 30 respondents obtained by using purposive sampling method. The respondents did a brisk walk on a treadmill at 50-63 % heart rate maximum intensity for 30 minutes. Blood was taken before and after the exercise in order to examine the levels of serum chloride. The results of this study were processed by using Wilcoxon test. Averagely, the level of serum chloride before exercise was 106,23 ± 2,208 mmol/L, and 106,90 ± 1,9 mmol/L after exercise. Statistical test result showed p = 0,007. It is concluded that there is a significant difference on the levels of serum chloride before and after light intensity exercise in the students of Medical Faculty Sam Ratulangi University.

Background: Sedentary behavior is one of the leading modifiable risk factors for cardiovascular disease and all-cause mortality. Physical exercise exerts beneficial physiological effects on cardiovascular fitness. Different grades of physical exercise have different effects on cardiovascular health. Objective: To compare the effect of moderate and high intensity exercise training on heart rate variability (HRV) in sedentary office workers. Methods: This study was conducted on 40 healthy sedentary volunteers aged between 20-40 years of both the genders. Participants were distributed into two groups of 20 subjects each. Subjects of group I and group II performed moderate intensity and high intensity exercise respectively on bicycle ergometer for 12 weeks. Their 5- minute ECG recording was done by three channel physiograph, and frequency domain indices of HRV and heart rate (HR) were analyzed and compared before and after exercise training. Their blood pressure was also recorded and compared before and after exercise training. Independent sample t-test and paired sample ttest were used for statistical analysis. Results: HF, systolic and diastolic blood pressure reduced significantly after exercise in group II (p=0.015, 0.005, and 0.015 respectively) while HR and LF/HF ratio reduced in both group I and group II (p=0.000 for HR, and 0.034, 0.001 for LF/HF). The decrease in HR was greater after high intensity exercise than moderate intensity exercise (p= 0.025). Conclusion: Parasympathetic activity improves after moderate and high intensity exercise but improvement is more after high intensity exercise training. Therefore, high intensity exercise training is more beneficial than moderate intensity exercise training. J Bngladesh Soc Physiol 2021;16(1): 16-23

Cardiometabolic Profile

Background: Menopause is associated with negative cardiovascular adaptations related to estrogen depletion, which could be counteracted by physical exercise (PhE). However, the impact of total adherence-rate (TA) to PhE and sedentary time (SedT) on cardiometabolic profile in this population has not been elucidated. Methods: For 13-weeks, 43 women (57.1 ± 4.7 years) participated in a 4-days-a-week moderate-intensity walking training. They underwent laboratory, anthropometric and echocardiographic assessment, before and after training (T0–T1). Spontaneous physical activity (PhA) was assessed with a portable multisensory device. The sample was divided according to TA to PhE program: <70% (n = 17) and ≥70% (n = 26). Results: TA ≥ 70% group experienced a significant T1 improvement of relative wall thickness (RWT), diastolic function, VO2max, cortisol, cortisol/dehydroandrostenedione-sulphate ratio and serum glucose. After adjusting for SedT and 10-min bouts of spontaneous moderate-to-vigorous PhA, TA ≥ 70% showed the most significant absolute change of RWT and diastolic function, body mass index, weight and cortisol. TA ≥ 70% was major predictor of RWT and cortisol improvement. Conclusions: In a group of untrained, postmenopausal women, a high TA to a 13-weeks aerobic PhE program confers a better improvement in cardiometabolic profile, regardless of SedT and PhA levels.

Background: The death of β cells Langerhans islets in Diabetes Mellitus (DM) can cause  loss of Langerhans islet function and worsen the progression of DM. Physical exercise plays a major part in DM treatment.Aim: to observe the effect of moderate intensity exercise to β (beta) cell numbers and Langerhans islets area size in Streptozotocin (STZ) induced diabetes in rats.Methods: Thirty adult male Wistar rats (Rattusnorvegicus) divided into 3, Group 1 as the control, Group 2 received 35 mg/kg streptozotocin induction treatment, Group 3 received 35 mg/kg streptozotocin induction and physical exercise, swimming, with moderate intensity 70% from the swimming maximal ability, 9% of body weight load, 4 times a week for 4 weeks. Datas collected were in the form of histopathology slide of pancreatic tissue after receiving treatment for 28 days.Results: There are significant differences of β-cell pancreas number between group K1 and K2 (p<0,001), group K2 and to K3 (p<0,001). No significant difference between group K1 and K3 (p=0,102). The Langerhans islets area sizes of pancreas tissue between group K1, K2, and K3 are significantly different (p<0,001).Conclusion: This study shows moderate-intensity physical exercise can increase the number of β cell and average area size of Langerhans islets. The effect of physical exercise depends on the intensity of exercise and the capacity of pancreatic function left of the diabetic.

The purpose of the present study was to investigate training-specific adaptations to eight weeks of moderate intensity continuous training (CT) and sprint interval training (SIT). Young healthy subjects (n = 25; 9 males and 16 females) performed either continuous training (30–60 min, 70–80% peak heart rate) or sprint interval training (5–10 near maximal 30 s sprints, 3 min recovery) three times per week for eight weeks. Maximal oxygen consumption, 20 m shuttle run test and 5·60 m sprint test were performed before and after the intervention. Furthermore, heart rate, oxygen pulse, respiratory exchange ratio, lactate and running economy were assessed at five submaximal intensities, before and after the training interventions. Maximal oxygen uptake increased after CT (before: 47.9 ± 1.5; after: 49.7 ± 1.5 mL·kg−1·min−1, p < 0.05) and SIT (before: 50.5 ± 1.6; after: 53.3 ± 1.5 mL·kg−1·min−1, p < 0.01), with no statistically significant differences between groups. Both groups increased 20 m shuttle run performance and 60 m sprint performance, but SIT performed better than CT at the 4th and 5th 60 m sprint after the intervention (p < 0.05). At submaximal intensities, CT, but not SIT, reduced heart rate (p < 0.05), whereas lactate decreased in both groups. In conclusion, both groups demonstrated similar improvements of several performance measures including VO2max, but sprint performance was better after SIT, and CT caused training-specific adaptations at submaximal intensities.
