Effect of a High-Intensity Circuit Training Program on the Physical Fitness of Wildland Firefighters.

Wildland firefighting implies high physical and psychological demands for the personnel involved. Therefore, good physical fitness can help increase the work efficiency of wildland firefighters (WFFs) and safeguard their health. High-intensity circuit training (HICT) could be a good alternative to improve the physical condition of WFFs since it stands out for its functionality and economy. Therefore, the objective of this study was to analyze the effects of HICT on the WFFs' physical fitness. The study involved 9 WFFs (8 males and 1 female; 29.8 ± 2.8 years; 175.6 ± 6.7 cm) who completed a training program and 9 WFF candidates (8 males and 1 female; 24.7 ± 6.6 yr, 176.5 ± 7.0 cm) as a control group. WFFs performed an 8-week HICT program (two weekly training sessions). The training sessions lasted approximately 45 min and were performed at an intensity >80% of maximal heart rate and RPE values >7.5. At the beginning and the end of the intervention, subjects' physical fitness (i.e., aerobic capacity, cardiorespiratory endurance, muscular resistance and explosive strength) was assessed through different tests. After completing the training program, WFFs had significantly increased (p < 0.05) the speed at which the ventilatory thresholds were determined (12.4 ± 13.9 and 5.7 ± 7.3% for the ventilatory and respiratory compensation thresholds, respectively) and also their abdominal (31.2 ± 17.2%), lumbar (34.1 ± 13.5%) and upper limb (13.3 ± 16.0%) strength. Moreover, improvements (p < 0.05) in the explosive strength of legs (7.1 ± 5.8%) and performance in a specific physical employment test (12.2 ± 6.1%) were observed. In conclusion, the results of this study show that an 8-week high-intensity circuit training program could be an effective and safe method to improve WFFs' physical fitness and performance.

Effect of resistance circuit training on health-related physical fitness, plasma lipid, and adiponectin in obese college students.

The purpose of this study is to investigate the effects of resistance circuit training on health-related physical fitness, plasma lipid and adiponectin in obese college students. Twenty male college students participated in this study and they were randomly divided into the sedentary group (SG, n=10) and the resistance circuit training group (RCG, n=10). The exercise group underwent the resistance circuit training program for 60 min 3 times a week for 12 weeks, while the sedentary group continued activities of daily living as usual. The levels of health-related fitness, blood lipid, and adiponectin were measured twice before and after the experiment. To analyze the statistically significance of collected data, Two-way repeated measure analysis of variance was used to determine the changes in the groups over the training period. A paired t-test was used to verify the difference within each group, and an independent t-test was used to verify the difference between the groups. In this study, the body composition including body fat mass, percent body fat and body mass index were significantly decreased in RCG compared to those in SG, and the health-related fitness showed a significant difference between RCG and SG. In addition, RCG positively modulated blood concentration of total cholesterol, triglycerides, high-density and low-density lipoprotein cholesterol. However, plasma adiponectin concentration did not show any significant differences between the two groups. Therefore, the present data suggested that resistance circuit training might be regulator to improve health-related physical fitness and decrease the level of plasma lipid in obese male college students.

Effect of 8-Week Circuit Training on the Development of Different Forms of Muscle Strength in Physical Education

The aim of the research was to determine the effect of an 8-week circuit training program on explosive strength and strength endurance in physical education classes intended for high school students. The research included 60 students of two second-grade high school classes. Both classes attended regular physical education classes, where, within the main part of the class, one class had a special program for developing strength through circuit training (circuit group), while the other one had no modifications to the regular physical education program (control group). The classes were randomly marked as circuit group (n = 28) and control group (n = 32). Five strength tests were used in the study: squat jump, countermovement jump, squats, push-ups, and sit-ups. The results showed that the 8-week strength development program organized as circuit training contributed to a significant improvement in strength. The results of all tests showed a significant effect of training on students’ strength. It has been determined that short-term circuit training in physical education classes is an effective way to develop students’ physical performance.

Abstract CT531: A 16-week circuit interval-based exercise intervention reduces systemic inflammation in obese, sedentary cancer survivors

Abstract Introduction: Obesity and a lack of physical activity lead to systemic and chronic inflammation among cancer survivors, which are highly associated with various comorbidities (e.g., type 2 diabetes, hypertension, and metabolic syndrome) and poor oncologic prognosis. Exercise, optimized to benefit physiological responses, can be an effective strategy to reduce systemic inflammation. The objective of the study was to investigate the effects of a 16-week circuit, interval-based exercise training program on proinflammatory cytokines in cancer survivors who are obese and sedentary. Methods: This study was a single center, pilot randomized controlled trial in 90 survivors of breast, prostate, and colorectal cancers who were sedentary (&amp;lt;60 mins of exercise per week) and overweight/obese (body mass index &amp;gt; 25.0 kg/m2). Participants were randomly assigned to either the exercise group (n=60) or the usual care group (n=30). The exercise intervention was moderate to vigorous intensity aerobic (65-85% of VO2max) and resistance (65-85% of 1-repetition maximum) exercise training in a supervised, circuit, interval-based format performed thrice-weekly for 16 weeks. Blood samples were obtained at baseline and post-intervention to measure serum levels of proinflammatory cytokines, including interleukin (IL)-6, IL-8, tumor necrosis factor-α (TNF-α), and high-sensitive c-reactive protein (hsCRP). Paired t-test and repeated measure ANOVA were used to determine the between-group differences. Results: Participants were aged 63.2±10.8 years and diagnosed with breast (35%), prostate (30%), and colorectal (35%) cancers. 55% were female and mean BMI was 34.7±5.9. 75% completed chemotherapy and/or radiation therapy. Retention and adherence rates to the exercise intervention was high (100% and 92%, respectively). Compared to usual care, circuit, interval-based exercise significantly reduced IL-6 (between group mean difference, -1.2 pg/mL; p&amp;lt;0.001), IL-8 (-2.4; p&amp;lt;0.001), TNF-α (-1.9 pg/mg; p&amp;lt;0.001), and hsCRP (-0.8 mg/L; p=0.02). Conclusions: A 16-week circuit, interval-based aerobic and resistance exercise training program induced a reduction in systemic levels of proinflammatory cytokines among sedentary and obese breast, prostate, and colorectal cancer survivors. Our findings suggest that combined aerobic and resistance exercise may be an effective strategy to offset elevated systemic inflammation associated with obesity and sedentary behavior in cancer survivors.

Effects of Circuit Training Program on Cardiovascular Risk Factors, Vascular Inflammatory Markers, and Insulin-like Growth Factor-1 in Elderly Obese Women with Sarcopenia.

Sarcopenic obesity is caused by a decrease in muscle mass and an increase in body fat due to aging, and has been the cause of cardiovascular diseases such as hypertension, diabetes, hyperlipidemia, and arteriosclerosis and high inflammatory conditions. However, there is a lack of research on the effects of long-term exercise training as regards to the body composition and blood-related physiological indicators. Therefore, the purpose of this study was to investigate the influences the effect of circuit exercise training for 12 weeks on cardiovascular risk factors, vascular inflammatory markers, and insulin-like growth factor-1 (IGF-1) in elderly obesity women with sarcopenia. A total of 28 elderly obese Korean women with sarcopenia (75.0 5.1 years) were randomly assigned either to a control group (CG, n = 14) or an exercise group (EG, n = 14). The EG performed circuit exercise training for 25-75 minutes (gradually incremental) three times per week over a period of 12 weeks, while the CG maintained their usual daily lifestyle during the intervention period. Pre- and post-intervention evaluations were performed on selected cardiovascular risk factors, inflammatory markers, and IGF-1. The EG group exhibited improved body composition (i.e., body mass index, fat-free mass, % fat mass, waist-to-hip ratio; all p 0.030, 2 0.169), Cardiovascular risks factor (i.e., heart rate, systolic blood pressure, rate pressure product, high-density lipoprotein cholesterol, total cholesterol/HDL-C ratio, triglyceride/HDL-C ratio, low-density lipoprotein cholesterol/HDL-C ratio, brachial-ankle pulse wave velocity, fasting plasma insulin, homeostasis model assessment-insulin resistance; all p 0.042, 2 0.150), Inflammatory markers (i.e., high sensitivity C-reactive protein, interleukin-6; all p 0.045, 2 0.146), and IGF-1 (p = 0.037, 2 = 0.157). Conversely, there were no significant changes observed in CG. Twelve weeks of circuit training had a positive effect on the improvement in cardiovascular risk factors, vascular inflammatory markers, and IGF-1 in elderly obese women with sarcopenia.

Civilians Have Higher Adherence and More Improvements in Health With a Mediterranean Diet and Circuit Training Program Compared With Firefighters.

To examine the relationship between diet adherence and cardiovascular disease (CVD) risk-reduction between civilians and firefighters with a 6-week Mediterranean diet and tactical training intervention. Forty firefighters and 30 civilians participated. Blood pressure, body composition, lipid levels, vascular measures, and aerobic capacity were measured pre- and post-intervention. Diet was self-report based on number of servings consumed. Weekly diet-scores were calculated. Both groups had improvements in blood pressure and body composition. Civilians had improved lipid levels, higher overall adherence, a relationship between total Med-diet score and cholesterol (R = 0.68), and higher servings consumed in foods typical of Mediterranean-dietary pattern ( P < 0.05). This is the first exercise and diet intervention comparing firefighters to civilians. Adherence to a Mediterranean-dietary pattern coupled with exercise is effective at improving cardiac health. These findings substantiate the need for wellness interventions in firefighters.

Effects of Intensity Modulated Total-Body Circuit Training Combined with Soccer Training on Physical Fitness in Prepubertal Boys after a 6-Month Intervention.

The purpose of this study was to examine the effects of a 6-month high- or moderate-intensity total-body circuit training (CT) program on physical fitness in prepubertal soccer players. Sixty-seven prepubertal boys with a mean age of 11.2 ± 0.7 years completed the study. Participants from a soccer academy were randomly assigned either to a high-intensity CT group (HCT, n = 22) or a moderate-intensity CT group (MCT, n = 24). A control group (CON, n = 21) comprised age-matched individuals who were not involved in any regular training regime. CT protocols were included in the experimental group’s training sessions 3 times per week over 24 weeks as part of their usual weekly training regime. Based on the HR zone method, CT protocols included high- or moderate-intensity (85–95% HRmax or 75–85% HRmax) series of 3 different sets of upper- and lower-body strength exercises with articular and muscular mobilization, all culminated with 40-m sprints. Physical fitness was evaluated by the Eurofit test which included the flamingo balance (FLB), plate tapping (PLT), sit-and-reach (SAR), standing broad jump (SBJ), handgrip (HG), sit-ups (SUP), bent arm hang (BAH), 10×5 m shuttle run (SHR), and the Physical Working Capacity test (PWC170). The two-way ANOVA indicated group×time interaction effects for 5 components: the largest was for the SBJ (F2,63 = 42.895, p < 0.001, η2 = 0.577), and the lowest for the SHR (F2,63 = 5.006, p < 0.01, η2 = 0.137) indicating better improvements in the HCT compared to the MCT group. Furthermore, for HCT and MCT groups the highest pre- to post-intervention percentage changes were for the FLB and the SAR, while in the CON group the changes of all physical fitness components were not significant (p < 0.05). In conclusion, the intensity-controlled total-body CT protocol incorporated into a standard soccer training program is effective for enhancement in physical fitness performance in prepubertal soccer players.

COMPARATIVE STUDY OF CIRCUIT AND AEROBIC DANCE TRAINING IN NUTRITIONAL STATUS AND BODY FAT OF OVERWEIGHT URBAN SCHOOL GIRLS

Centering upon the suffering from chronic energy deciency due to overweight and high body fat is very common problem in urban school girls of our society. In present days, in this pandemic situation, a compulsion practice and system of staying inside the home and intake of more amount of food without having any physical exercise, gives the gift birth of overweight status of our children. From this point of view, the researcher intends to investigate a comparative study of circuit and aerobic dance training programmes to reduce body fat and for adopting heathy weight and BMI and also to investigate which programme is more effective. Ninety, seventh and eight standard obese girls of Kalitala girls high school (N = 45) and Mission Girls High School (N = 45) mean age (13+1) years of Bankura district of West Bengal, India were randomly selected as the subjects for the study. For experimental purpose total ninety subjects were sub-divided systematically on the basis of over-weight status into three equal groups (n = 30). The circuit training and aerobic dance programs were randomly assigned to two groups which were designated as experimental groups: Group A (Circuit Training) and Group B (Aerobic Dance) and were imparted 12 weeks of circuit training and aerobic dance training programs, respectively whereas the remaining group was designated as the control group (Group C).

Firefighters On Medication Have Worse Health Profiles But Larger Improvements With Diet &amp; Exercise

Heart disease and sudden cardiac death account for an overwhelming number of on- and off-duty deaths in firefighters (FF). The alarm response, the FF lifestyle, and the heavy work of the job all add to the stress of firefighting. These inherent risks aggravate existing CVD, many FF are on medication regimen, yet it is unknown whether medication status affects vascular health in FF. Furthermore, using ambulatory BP (ABP) monitors to quantify the BP surge with alarm is a novel way to assess CVD risk in FF. PURPOSE: To compare changes in health after a 6-wk Mediterranean diet & circuit training program between medicated (MedFF) or non-medicated (NmFF) FF. METHODS: We included 40 FF who completed a 6-wk intervention. Pre- and post-testing included ABP monitoring, a fasted clinical appt, and fitness test. FF wore the ABP cuff for 12-hrs and were paged by emergency service dispatch or by a pager app (OnPage). When the pager sounded, they forced an ABP reading to measure BP surge. Fasted visit included BP, body fat, lipid panel, blood draw, and vascular health measures. VO2peak was measured on treadmill. Serum was isolated for ELISA analysis of superoxide dismutase (SOD) and C-reactive protein (CRP). RESULTS: MedFF were on medication for BP, cholesterol, and multiple other types. Nine of the FF reported multiple medications. MedFF (N = 19, 48.4 ± 2 yrs) had worse health and higher BP surges, but more improvements with diet+exercise compared to NmFF (N = 21, 31.7 ± 2 yrs), P < 0.05 with differences. MedFF had higher BP (130.2/81.3 vs 121.6/77.7 mmHg), higher average ABP (133.7/80.4 vs 123.7/75.2 mmHg), lower VO2peak (33.3 vs 37.1 ml/kg-min), lower FMD (8.5 vs 10.2 %), higher PWV (7.4 vs 5.7 m/s), and higher CRP (3.8 vs 3.1 mg/L) levels. MedFF also tend toward larger SBP and DBP surges with alarm (15.9 vs 13.9 mmHg SBP and 9.9 vs 8.1 mmHg DBP) and an improvement in surge after intervention (SBP surge 15.9 to 8.6 in MedFF vs 13.9 to 15.8 mmHg in NmFF; DBP surge 9.9 to 3.7 in MedFF vs 8.1 to 5.4 mmHg in NmFF). With intervention we found that BP lowered, body composition, vascular health, and VO2peak improved in MedFF. CONCLUSION: With this subset of data, we show that FF on medication have worse health profiles but may have larger improvements with exercise + diet. Data confirms the importance of wellness programs in the firehouse, in particular for FF already on medication.
