Effects of circuit weight training by intensity on stress hormones and antioxidant capacity in high-school wrestlers.

We aimed to investigate the effects of 8-week circuit weight training by intensity on blood stress hormones and antioxidant capacity in high-school wrestlers. This study involved 27 male wrestlers with >2 years of wrestling experience who were randomly assigned to either a low intensity (n=13) or a high-intensity circuit weight training group (n=14). The participants performed circuit weight training for 60 min per session, 3 times per week for 8 weeks. The low- and high-intensity circuit weight training exercises were performed at 50%-60% and 70%-80% of one-repetition maximum for 10 stations, respectively, and 8-15 repeated sessions per station were performed in order. No changes were observed in adrenocorticotropic hormone (ACTH), cortisol, epinephrine, and norepinephrine levels between the two training groups. When compared to levels before the training, ACTH and epinephrine levels decreased, whereas cortisol levels increased. However, no difference was observed in norepinephrine levels. Further, no differences were observed in malondialdehyde (MDA) and glutathione peroxidase (GPX) levels between the two groups. However, MDA and GPX levels were increased from those before training. Changes in superoxide dismutase levels were observed between the two groups, but the change was significant only in the high-intensity circuit weight training group. Long-term training did not increase lipid peroxidation, but increased the activity of antioxidant enzymes that defend against oxidative stress. The antioxidant defense system in tissues can be regulated by exercise intensity as well as physical training status.

Effect of circuit weight training on aerobic fitness, body fat percentage, muscle mass percentage, and hand grip strength in the elderly

The purpose of this study was to determine the effect of weight training using circuit methods on aerobic fitness, body fat percentage, muscle mass percentage, and hand grip strength. This study is a one-group pretest-posttest quasi-experimental study with a sample of the elderly gymnastics group Sehat Bugar Ceria in Karanganyar Regency, Indonesia. Twenty-seven study subjects aged 60–75 participated in the exercise for 12 meetings. All research subjects can take all pretests and posttests in the form of a six-minute walk test, a hand grip strength test using a handgrip dynamometer, and body composition testing using bioelectrical impedance analysis. Changes that occurred before and after exercise were analyzed using paired t-tests. This study showed that aerobic fitness increased significantly (p = 0.001), body fat percentage decreased significantly (p = 0.008), but there was no significant change in the percentage of muscle mass (p 0.05) or hand grip strength (p 0.05). The results of this study showed that weight training using circuit methods can improve aerobic fitness and reduce body fat percentage in the elderly group.

The purpose of this study was to investigate the effects of circuit weight training and weight training on aerobic capacity and health-related fitness in obese male college students. In this study 16 obese male college students attending G-city University without medical history were selected as subjects. These subjects were randomly assigned to circuit weight training group (n=8) and weight training group (n=8). The subjects in circuit(three circuits using a work-to-rest ratio of 30s:30s) and weight training program performed for 8 weeks, 3 times a week on non-consecutive days at 40 and 80% of one-repetition maximum(1RM), respectively. The maximum oxygen uptake(VO₂max) and oxygen uptake(VO₂) at anaerobic threshold(AT) were measured as the aerobic capacity. Also, body composition, muscular strength, and muscular endurance were measured and analyzed as the health-related fitness. Based on the results of the study, the following results were obtained. First, the maximum oxygen uptake and oxygen uptake at anaerobic threshold were significantly increased (p<.01) in the circuit weight training group, but there was no significant difference in the weight training group. Second, there was a significant decrease (p<.01) in body weight in the circuit weight training group, and a significant decrease (p<.001) in body fat(%) in both groups. In contrast, lean body mass was increased in both groups, but there was no significant difference. Third, There was a significant difference (p<.001) in muscular strength and muscular endurance in both groups. Therefore, circuit weight training may also be an effective exercise method for increasing potential aerobic capacity and reducing body fat in changes in body composition.

The Effects of Circuit Weight Training and Weight Training on Foot Pressure in Healthy Adults

Objectives: This study aims to identify the effects of circuit weight training and weight training on foot pressure. Methods/ Statistical Analysis: The 20 young participants were divided into a Circuit Weight Training Group (CWTG) and a Weight Training Group (WTC) with ten participants in each group. A gait analyzer was utilized to assess on plantar pressure of subjects. The plantar pressure of ten spots was measured and analyzed. A paired samples t-test was used before and after the exercise in the CWTG and the WTG. Findings: This study shows the two groups’ changes in plantar pressure after the exercise as compared to before the exercise. The CWTG saw a significant increase in plantar pressure in two of the ten areas (F6, R1) and the WTG saw a significant increase in five of the ten areas (F4, F5, F6, R3, R4). After the four-week exercise program, the WTG’s plantar pressure significantly increased in five of the ten areas of the sole, with a significant increase in the middle foot. The CWTG’s plantar pressure significantly increased in two of the ten areas of the sole, the great toes and the outer areas of the heels. This means that the CWTG’s plantar pressure is closest to the normal movement of plantar pressure. Improvements/Applications: The CWTG exercise method resulted in a normal gait pattern, which had a more positive effect on gait than weight exercise.

Impact of Resistance Circuit Training on Neuromuscular, Cardiorespiratory and Body Composition Adaptations in the Elderly

Declines in maximal aerobic power and skeletal muscle force production with advancing age are examples of functional declines with aging, which can severely limit physical performance and independence, and are negatively correlated with all cause mortality. It is well known that both endurance exercise and resistance training can substantially improve physical fitness and health-related factors in older individuals. Circuit-based resistance training, where loads are lifted with minimal rest, may be a very effective strategy for increasing oxygen consumption, pulmonary ventilation, strength, and functional capacity while improving body composition. In addition, circuit training is a time-efficient exercise modality that can elicit demonstrable improvements in health and physical fitness. Hence, it seems reasonable to identify the most effective combination of intensity, volume, work to rest ratio, weekly frequency and exercise sequence to promote neuromuscular, cardiorespiratory and body composition adaptations in the elderly. Thus, the purpose of this review was to summarize and update knowledge about the effects of circuit weight training in older adults and elderly population, as a starting point for developing future interventions that maintain a higher quality of life in people throughout their lifetime.

Effects of Circuit Weight Training on Fitness in College-Aged Women

Circuit weight training (CWT) has been a popular form of exercise for more than three decades. However, little research has examined the effects of a single CWT program on multiple components of fitness. PURPOSE: The purpose of this study was to assess the effects of CWT on body composition (BC), VO2peak, bone mineral density (BMD), bone mineral content (BMC), muscular strength (MS) and muscular endurance (ME). METHODS: Twenty-four young adult women 18 to 35 years of age were randomly assigned to one of two groups: circuit weight training group (CTG; n=12) or control group (CN; n=12). The CTG exercise sessions (20 min, 3d wk−1 for 8 wk) consisted of a 5 minute warm-up on the treadmill followed by a CWT routine (10 stations, 30/30 sec work-to-rest ratio). Resistance was initially set at 60% of 1-repetition maximum and increased 2.5 lb every two weeks. CN was asked to remain inactive throughout the 8-wk study. CTG and CN were asked to maintain their usual dietary patterns throughout the 8-wk study and completed a 3-day dietary log during week one and week eight to verify compliance. RESULTS: Compared to CN, CTG improved (p <0.05) on several measures: BMD (1.8%), lean body mass (LBM) (1.2%), fat mass (FM) (−2.4%), body fat percentage (BF %) (−1.9%), upper MS (22.7%), lower MS (22.9%), upper ME (23.3%) and lower ME (20.8%). Although VO2peak did not improve (−2.9%) in CTG, there were some identifiable tendencies within CN that may have affected the results of this variable. CTG observed no improvements for height, weight, and BMC. CONCLUSION The results of this study indicate that this CWT program enhances LBM, FM, BF%, BMD, MS, and ME in college-aged women. Additional research is needed to identify the effects of CWT dosage (sets, repetitions, frequency, intensity, duration, work-to-rest ratio) on these fitness parameters.

Spinal shrinkage in females: circadian variation and the effects of circuit weight-training.

Compressive loading of the spine leads to spinal shrinkage and a loss of stature. The aim of this study was to measure the circadian variation in the stature of females and to examine differential effects of spinal loading with the time of day. Ten females aged 20–30 years were studied in nine measurements on a 24-hour period. Between rising and retiring to bed, the mean peak-to-trough variation was 15·4 mm (0·92% of stature). Subjects underwent two sequences of 20 min circuit-training with weights, followed by 20 min reclining in Fowler's position and 20 min standing erect, these being first thing in the morning after 7 hours of sleep and before retiring at midnight. Mean loss of height from circuit-training was 5·4 mm in the morning and 4·3 mm in the evening (P < 0·001): mean height regained in Fowler's position was 4·5 mm and 3·4 mm respectively (P<0·05). There were significant height losses in the subsequent standing posture but no time of day effect. Height losses with exercise were related to the is...

Self-efficacy mediates strength gains during circuit weight training in men with coronary artery disease

Motivation to engage in health-promoting exercise has been ascribed to global personality traits such as self-esteem or athletic self-confidence. Self-Efficacy Theory challenges this view by proposing that highly specific estimates of personal capabilities mediate adoption of new or difficult behavior patterns. We tested this assumption by measuring self-efficacy perceptions in 40 men with coronary artery disease who participated in an experiment evaluating effects of circuit weight training (CWT). Specific self-efficacy estimates were assessed during baseline strength/endurance testing and after 10 wk participation in CWT or volleyball. Correlational analyses of self-efficacy in relation to performance on strength/endurance tests strongly supported the contention that adoption of novel activities is governed by highly specific self-perceptions. Participation in CWT produced greater strength and endurance gains than did volleyball, and these changes were accompanied by increased self-efficacy in CWT subjects for activities resembling the training tasks. The assertion that self-efficacy perceptions directly mediate involvement in challenging physical activities was supported by multiple regression analyses. These revealed that pre-training self-efficacy judgments predicted post-test strength gains even after controlling for baseline strength, type of training and frequency of participation in exercise sessions.
