“…Same study conducted by Freeman et al (2006) argued that heart recovery rate is indicated by the difference between peak level of heat rate through exercise and reduced heart rate after one minute to exercise. In this connection, Malandish et al (2020) confirm that girls with moderate intensity exercise, by using bicycles and jogging for three months, got improved HRR, autonomic system and reduced breast cancer were noted among them in diverse situations.…”

The existing stud was aimed to observe effects of moderate intensity aerobic exercises upon heart recovery of college girls. The study was experimental by using longitudinal data collection approach i.e., pre-test and post-test. Total participants in study were 40. The selected population was randomly being divided into two groups, “experimental and control group”. The experimental group gained special treatment for a period of 8 weeks. The heart beat was checked through Radial artery which is easily felt on thumb side of the wrist of arm. For radial artery, three fingers of hand used. After the completion of eight-week exercise protocol data of RHR the data of pretest and posttest was recorded and analyzed “using paired sample t test” to see the difference between the RHR score of girls in pre-test and post-test. It was concluded that the “there is significant impact of Moderate intensity aerobic exercises upon Resting” Heart Rate. Study provides significant information in reaching the conclusion of the current research study.

“…Finally, it was important to monitor ECG readings before and after exercise, as it was not previously examined. The approximately 9 ms increase in PR interval following exercise ( Table 2 and Supplemental Table 2 ) was not unexpected, as first-degree atrioventricular blocks are commonly seen in healthy aerobically trained individuals ( 28 , 29 , 42 ). Furthermore, a recent clinical trial in DM1 patients reported similar increases in the PR interval following a 6-month follow-up period in both the placebo and mexiletine groups ( 38 ), indicating a partial effect of aging per se.…”

Background Myotonic dystrophy type 1 (DM1) is a complex life-limiting neuromuscular disorder characterized by severe skeletal muscle atrophy, weakness, and cardiorespiratory defects. Exercised DM1 mice exhibit numerous physiological benefits that are underpinned by reduced CUG foci and improved alternative splicing. However, the efficacy of physical activity in patients is unknown. Methods Eleven genetically diagnosed DM1 patients were recruited to examine the extent to which 12 weeks of cycling can recuperate clinical and physiological metrics. Furthermore, we studied the underlying molecular mechanisms through which exercise elicits benefits in skeletal muscle of DM1 patients. RESULTS DM1 was associated with impaired muscle function, fitness, and lung capacity. Cycling evoked several clinical, physical, and metabolic advantages in DM1 patients. We highlight that exercise-induced molecular and cellular alterations in patients do not conform with previously published data in murine models and propose a significant role of mitochondrial function in DM1 pathology. Finally, we discovered a subset of small nucleolar RNAs (snoRNAs) that correlated to indicators of disease severity. Conclusion With no available cures, our data support the efficacy of exercise as a primary intervention to partially mitigate the clinical progression of DM1. Additionally, we provide evidence for the involvement of snoRNAs and other noncoding RNAs in DM1 pathophysiology.

“…In present study, we show the increase of 25(OH)D 3 concentration by the average of 2.9 and 3.0 nmol L −1 , 15 min and one hour after the exercise, respectively. Previously, a study on postmenopausal women showed that 12-week of moderate-intensity aerobic exercise, with no additional vitamin D supplementation, increased serum vitamin D concentration, as severe vitamin D deficiency status (below 10 ng mL −1 ) was improved to vitamin D deficiency status (between 10 and 20 ng mL −1 ) 39 . The recent investigation also reported that 20 weeks of human resistant training, without vitamin D supplementation, increased plasma 25(OH)D 3 concentration from 42.4 to 51.2 nmol L −1 , as well it induced the expression of CYP27B1, which positively correlated with an up-regulation of VDR 9 .…”

“…Nevertheless, both WAnT and VO 2max tests could change the 25(OH)D 3 concentration. Previously mentioned studies 41,42 show that the increase of 25(OH)D 3 concentration was maintained for 24 h after acute endurance exercises and that resistance 9 and endurance 39 training can enhance the change in the blood 25(OH)D 3 concentration. It is well documented that acute training cannot cause as profound adaptive response in the organism as training does.…”

Vitamin D is necessary for musculoskeletal health, however, the supplementation of vitamin D above the sufficiency level does not bring additional bone mass density (BMD), unlike physical exercise which enhances the bone formatting process. Regular physical activity has been shown to upregulate VDR expression in muscles and to increase circulating vitamin D. Here we investigate whether a single bout of exercise might change 25(OH)D3 blood concentration and how it affects metabolic response to exercise. Twenty-six boys, 13.8 years old (SD ± 0.7) soccer players, participated in the study. The participants performed one of two types of exercise: the first group performed the VO2max test until exhaustion, and the second performed three times the repeated 30 s Wingate Anaerobic Test (WAnT). Blood was collected before, 15 min and one hour after the exercise. The concentration of 25(OH)D3, parathyroid hormone (PTH), interleukin-6 (IL-6), lactate, non-esterified fatty acids (NEFA) and glycerol were determined. 25(OH)D3 concentration significantly increased after the exercise in all boys. The most prominent changes in 25(OH)D3, observed after WAnT, were associated with the rise of PTH. The dimensions of response to the exercises observed through the changes in the concentration of 25(OH)D3, PTH, NEFA and glycerol were associated with the significant increases of IL-6 level. A single bout of exercise may increase the serum’s 25(OH)D3 concentration in young trained boys. The intensive interval exercise brings a more potent stimulus to vitamin D fluctuations in young organisms. Our results support the hypothesis that muscles may both store and release 25(OH)D3.
