Evidence in both humans and animals has shown that exercise before or during pregnancy may effect fetal outcome. The purpose of this investigation was to examine the effects of an exercise program on fetal development in the rat. Prior to impregnation one group of animals was exercise-trained on a Quinton shock-stimulus rodent treadmill. The exercised group was trained to run 5 days/wk, for 2.0 h/day at 31 m/min up an 8 degree incline for 8 wk before mating. Following mating the training intensity was reduced to 27 m/min up a 5 degree incline, and the exercise period decreased to 1 h/day. On day 19 of gestation, 24 h postexercise for the trained mothers, the animals were killed in the fed state and the maternal and fetal characteristics were measured. The sedentary controls gained significantly (P less than 0.05) more body weight during pregnancy. This can be attributed to three factors: higher number of fetuses, 14.83 +/- 0.04 vs. 12.2 +/- 0.85 for the trained; larger litter weights, 44.25 +/- 4.97 vs. 26.17 +/- 1.82 g/dam for the trained; and slightly larger lipid stores. In addition to having fewer pups the trained mothers had a greater number of fetal resorptions; 0.9/dam as opposed to 0.17/dam for the sedentary control. Analysis of fetal body composition showed no difference in total body water, protein, or fat between the pups of sedentary and trained dams. The results of this study indicate that exercise training prior to and during pregnancy influences fetal development in the rat.

The purpose of this investigation was to examine the relationship between an exercise program and fetal development to determine whether training could influence insulin sensitivity in the pregnant rat. Prior to impregnation one group of animals was exercise trained on a Quinton shock-stimulus rodent treadmill. The exercised group was trained to run 5 days/wk, for 2.0 h/day at 31 m/min up an 8 degree incline for 8 wk before mating. Following mating the training intensity was reduced to 27 m/min up a 5 degree incline, and the exercise period decreased to 1 h/day. On day 19 of gestation, 24 h postexercise for the trained mothers, the animals were killed in the fed state and the parametrial fat pads were removed. The parametrial depot of the trained mother was smaller than the sedentary control dam. This was due to a change in cell size and did not involve alterations in cell number. Isolated adipocytes of the parametrial fat pads were used to measure the rates of 2-deoxy-D-[3H]glucose uptake and D-[1–14C]glucose oxidation to 14CO2. The results indicated that the adipocytes from the dam trained prior to and during pregnancy were significantly (P less than 0.05) more responsive to insulin than those of animals remaining sedentary during the same period. At the maximal insulin concentration tested, the fat cells from trained mothers were able to take up and metabolize approximately twice as much glucose as the sedentary control dams. However, the increase in insulin responsiveness induced by the training program did not match the changes observed in trained nonpregnant rats of prior investigations.

Aerobic exercise training has many known cardiovascular benefits that may promote healthy aging. It is not known if long-term aerobic exercise training is also associated with structural benefits (e.g., lower fat mass, higher areal bone mineral density (BMD) and greater muscle mass). We evaluated these parameters in middle-aged long-term endurance runners compared to sex-, age-, height-, and weight-matched non-running controls. Total and regional lean and fat mass and areal BMD were assessed by dual-energy X-ray absorptiometry. Sagittal magnetic resonance images captured the cross-sectional area and thickness of the lumbar multifidus. Runners (n = 10; all male) had a mean (standard deviation; SD) age of 49 (4) years, height of 178.9 (4.9) cm, weight of 67.8 (5.8) kg, body mass index (BMI) of 21.4 (1.4) kg/m2 and had been running 82.6 (27.9) km/week for 23 (13) years. Controls (n = 9) had a mean (SD) age of 51 (5) years, height of 176.0 (5.1) cm, weight of 72.8 (7.1) kg, and BMI of 23.7 (2.1) kg/m2. BMI was greater in controls (p = 0.010). When compared to controls on average, runners had a 10 percentage-point greater total body lean mass than controls (p = 0.001) and 14% greater trunk lean mass (p = 0.010), as well as less total body (8.6 kg; p < 0.001), arm (58%; p = 0.002), leg (52%; p < 0.001), trunk (73%; p < 0.001), android (91%; p < 0.001), and gynoid fat mass (64%; p < 0.001). No differences were observed between groups for BMD outcomes or multifidus size. These results underscore the benefits of endurance running to body composition that carry over to middle-age.

Background and objectives: Faced with the serious problem of an aging population, exercise is one of the most effective ways to maintain the health of the elderly. In recent years, with the popularization of smartphones, the elderly have increasingly accepted technological products that incorporate artificial intelligence (AI). However, there is not much research on using artificial intelligence bracelets to enhance elders’ motivation and participation in exercise. Therefore, the purpose of this study is to evaluate the effectiveness of the combination of sports smart bracelets and multi-sport training programs on the motivation of the elderly in Macau. Materials and Methods: The study was conducted with a randomized trial design in a 12 week multi-sport exercise training intervention. According to the evaluation, a total of sixty elders’ pre- and post-test data were included in this study. Results: After 12 weeks of multi-sport exercise training, the evaluation scores on the exercise motivation scale (EMS) increased significantly in the group wearing exercise bracelets and those taking part in the multi-component exercise program, and the degree of progress reached a statistically significant level, but the control group did not show any statistically significant difference. The influence of the combination of sports smart bracelets and multi-sport training programs on elders’ motivation is clearer. Conclusions: The use of sports smart bracelets by elderly people in conjunction with diverse exercise training can effectively enhance elders’ motivation and increase their participation in regular exercise. The combination of sports smart bracelets and multi-sport training programs is worth promoting in the elderly population.

This study investigated the acute effect of exercise on sleep outcomes among healthy older women by comparing days with structured exercise versus days without structured exercise during 4 months of exercise training. Participants (n = 51) in this study had wrist-worn actigraphic sleep data available following at least 3 days with structured exercise and 3 days without structured exercise at mid-intervention and at the end of intervention. The exercise intervention was treadmill walking. Multilevel models were used to examine whether structured exercise impacted sleep outcomes during the corresponding night. Overall, 1,362 nights of data were included in the analyses. In unadjusted and adjusted models, bedtimes were significantly earlier on evenings following an acute bout of structured exercise than on evenings without structured exercise. No other sleep parameters differed between exercise and nonexercise days. Understanding the effects of exercise on sleep in this understudied population may help to improve their overall sleep quality.

The purpose of this study was to examine the effects of 10 weeks of aerobic endurance training (AET), resistance exercise training (RET), or a control (CON) condition on absolute and relative fat mass (FM) or fat-free mass (FFM) in the total body (TB) and regions of interest (ROIs) of sedentary overweight middle-aged males and females. Following prescreening, 102 subjects underwent anthropometric measurements, dual-energy X-ray absorptiometry, and strength and aerobic exercise testing. Randomized subjects (male RET, n = 16; female RET, n = 19; male AET, n = 16; and female AET, n = 25) completed supervised and periodized exercise programs (AET, 30–50 min cycling at 70%–75% maximal heart rate; RET, 2–4 sets × 8–10 repetitions of 5–7 exercises at 70%–75% 1 repetition maximum) or a nonexercising control condition (male CON, n = 13 and female CON, n = 13). Changes in absolute and relative TB-FM and TB-FFM and ROI-FM and ROI-FFM were determined. At baseline, and although matched for age and body mass index, males had greater strength, aerobic fitness, body mass, absolute and relative TB-FFM and ROI-FFM, but reduced absolute and relative TB-FM and ROI-FM, compared with females (p < 0.05). After training, both female exercise groups showed equivalent or greater relative improvements in strength and aerobic fitness than did the male exercise groups (p < 0.05); however, the male exercise groups increased TB-FFM and reduced TB-FM more than did the female exercise groups (p < 0.05). Male AET altered absolute FM more than male RET altered absolute FFM, thus resulting in a greater enhancement of relative FFM. Despite equivalent or greater responses to RET or AET by female subjects, the corresponding respective increases in FFM or reductions in FM were lower than those in males, indicating that a biased dose–response relationship exists between sexes following 10 weeks of exercise training.

This study aims to observe the possible negative effects that might occur on bio-chemistry and hemogram values of tennis players during the intense competition period by comparing the blood values of pre-competition period with 10 days of intense exercise. Blood samples were obtained from tennis team players who do not have any specific health problems and who study in university and regularly exercise. Mean age of the athletes are 22,40 ± 3,20 years and mean height is 179,83 ± 7,57 cm. This study is performed with 14 volunteer tennis players. Blood samples are obtained during the first day of the intense exercise program after the exercise, last day of the exercises and also right after the exercises. As per the obtained data, descriptive statistics are run (mean and standard deviation) and in order to compare the values of before and after the 10 days of intense exercise, Wilcoxon two related sample test was used. As per the results of the blood tests from before and after the exercise period, it is seen that values such as AST, ALT, MCH, MCHC and CK showed statistical significance (P<0.05). The athletes who prepared for the competitions with these values showed positive increases in bio-chemistry and hemogram values.

Objective: The goal of our study was to investigate the effect of different type of exercise training on C-reactive protein level in middle age men. Methods: A total of 20 male subjects’ mean age 45±5 years were investigated at the University of Jordan Hospital to evaluate CRP level after training. Subjects were divided randomly into two groups they participated in supervise exercise training resistance and endurance exercise for 11 weeks. CRP level was measured pre-post training. Results: Mean C-reactive protein level measured before training program was 1.82 mg/L. And 1.81 mg/L for endurance and resistance groups respectively. Measurement of the CRP after the completion of the exercise program was 1.654 mg/L and 1.764 mg/L for both groups the endurance and the resistance respectively. TC was significantly reduced from 199.1 ml/dl to 176.1 ml/dl, for the endurance group and from 193.50 ml/dl to 181.60 ml/dl, for the resistance group. TG reduced significantly from 172.2 ml/dl to 161.50 ml/dl for the endurance group, and from 163.50 ml/dl to 159.20 ml/dl for the resistance group. HR at rest reduced from 79.63 b.pm to 74.47 b.pm for the endurance group, and from 77.50 b.pm to 74.6 b.pm for the resistance group. Fat % reduced significantly from 25.25 to 23.22 for the endurance group and from 23.03 to 21.60 for the resistance group. BMI reduced from 28.82 to 27.41 for the endurance group and from 27.63 to 27.40 for the resistance group.VO2max increased significantly from 37.13 to 43.30 ml.kg.min for the endurance group, and from 37.67 to 39.3 for the resistance group. HDL also increased from 46.12 mi/dl to 48.25 mi/dl for the endurance group, and increased from 42.70 mi/dl to 44.30 mi/dl for the resistance group Training gropes had lower CRP, weight, BMI, and body fat after the completion of the exercise program. Conclusions: Plasma C-reactive protein levels are reduced in response to both strength and endurance exercise training in sedentary healthy men (there was no different in the type of exercise in reducing CRP level.

Forearm Vascular Resistance

Exercise training of a muscle group improves local vascular function in subjects with chronic heart failure (CHF). We studied forearm resistance vessel function in 12 patients with CHF in response to an 8-wk exercise program, which specifically excluded forearm exercise, using a crossover design. Forearm blood flow (FBF) was measured using strain-gauge plethysmography. Responses to three dose levels of intra-arterial acetylcholine were significantly augmented after exercise training when analyzed in terms of absolute flows (7.0 ± 1.8 to 10.9 ± 2.1 ml · 100 ml−1 · min−1 for the highest dose, P < 0.05 by ANOVA), forearm vascular resistance (21.5 ± 5.0 to 15.3 ± 3.9 ml · 100 ml forearm−1 · min−1, P< 0.01), or FBF ratios ( P < 0.01, ANOVA). FBF ratio responses to sodium nitroprusside were also significantly increased after training ( P < 0.05, ANOVA). Reactive hyperemic flow significantly increased in both upper limbs after training (27.9 ± 2.7 to 33.5 ± 3.1 ml · 100 ml−1 · min−1, infused limb; P < 0.05 by paired t-test). Exercise training improves endothelium-dependent and -independent vascular function and peak vasodilator capacity in patients with CHF. These effects on the vasculature are generalized, as they were evident in a vascular bed not directly involved in the exercise stimulus.

Objectives: To study the effect of four weeks of aerobic exercise training, on sleep quality and quality of life parameters like anxiety, depression and physical functioning in Post Myocardial Infarction (MI) patients. Methods: ST elevated MI patients (n=21, <65years age) were voluntarily divided into 2 groups, control group (n=11) and exercising group (n=10). The patients in experimental group followed an exercise program of 3 sessions per week for 4 weeks. The subjective quality of life, anxiety and depression levels were assessed by the SF 36 questionnaire and Hospital Anxiety & Depression Scale (HAD scale) and the sleep quality was assessed using Pittsburgh Sleep Quality Index (PSQI). Poor sleep quality and short sleep duration was defined as PSQI > 5 and total sleep time <6hrs. respectively. After 4 weeks of the program the questionnaires were repeated for all 21 patients. Wilcoxon rank order test and Student T test were used. P<0.05 was considered statistically significant Results: Intergroup analysis showed statically significant reduction in anxiety score (9vs0.5) and depression score (3vs0) in exercise group as compared to control group respectively. As compared to control group, exercise group also showed statistically significant improvement in the quality of life parameter score [physical functioning (750vs1000), role functioning physical (0vs400) & emotional (0vs300), energy level (215vs400), emotional well-being (400vs500), social functioning (120vs200), general health (230vs462.5) & health changes (50vs100)]. Intra group analysis also showed significant changes only in exercise group. After 4 weeks of exercise training, PSQI score improved in the experimental group from 9.5±4.11 to 1.13±0.35 (p=0.00029) indicating better sleep quality and duration. While it remained comparable to the baseline values in the control group i.e. from 9.9±4.70 to 10.33±3.87 (p value= 0.514). Conclusion: Four weeks of exercise program improves the quality & duration of sleep and quality of life in MI patients after 2 weeks of index event.

Abstract Background Although the evidence suggests that general fatigue is a strong indicator of rapid aging, frailty, and disability, general fatigue is undertreated in gerontological care. Objective The aim of this study is to investigate whether an individualized exercise program with and without behavioral change enhancement (BCE) strategies for older people who are frail and have general fatigue will reduce their fatigue and symptoms of frailty. Design A 3-arm, single-blind, cluster randomized controlled trial registered with ClinicalTrials.gov (NCT03394495) will be conducted. Setting The study will be conducted in a community setting. Participants Two hundred eighty-five community-dwelling older people with general fatigue will be recruited from 12 district community health centers. Intervention People from each center will be randomized to one of three groups. The combined group will receive a 16-week combined intervention consisting of individualized exercise training and the BCE program, plus two booster sessions at 2 and 6 months after the program. The exercise group will receive exercise training and health talks only. The control group will receive health talks only. Measurements Outcome measures will be collected at baseline, at the midpoint (week 8) of the program, and then at 1 week, 6 months, and 12 months after the end of the program. The primary outcome---level of fatigue---will be measured using the Multidimensional Fatigue Inventory. Secondary outcomes will include the participants’ frailty status, strength, mobility, exercise self-efficacy, and habitual physical activity. Limitations A self-reported level of fatigue will be used. Conclusions The effect of exercise and BCE strategies on general fatigue among older people who are frail is not known. This study will be a pioneering interventional study on how general fatigue among older people who are frail can be managed and how fatigue-related frailty can be prevented or minimized.
