... Tabata training consists of a series of movements involving several muscle groups of the body that can assist build muscle endurance and develop strength (Lee et al., 2021). High-intensity exercise, such as tabata, can increase the body metabolism, causing it to burn more calories even after training (Lu et al., 2023) Meanwhile, circuit training incorporates a variety of movements, such as weight training, cardio, strength, and flexibility (Heinrich et al., 2012), and is not usually performed at a high intensity (Wilke et al., 2019). Circuit training can be designed by integrating cardiovascular exercises, such as running in place or jump rope, between the strength training sets. ...

    Volleyball matches can be very long, especially if the two teams are evenly matched. Physical endurance is essential to maintain high performance during matches that may last up to five sets. Athletes who have good endurance can continue to move, jump, and perform fast movements throughout the game without experiencing excessive fatigue. Tabata training and circuit training are two types of training that focus on improving physical fitness with different methods, such as training duration and training format. The aim of this study was to examine the effect of tabata training and circuit training on increasing the endurance of volleyball athletes. In this research, researchers applied an experimental method with a pre-test post-test control group design. The research samples consisted of 30 athletes from the Tectona club in Cianjur Regency. The instrument for measuring the endurance of volleyball athletes was the yoyo test. Samples were receiving treatments 3 times a week with a total of 18 meetings. Hypothesis testing used paired sample-test and independent sample-test analysis. The research results showed that both tabata training and circuit training had an effective influence in increasing endurance of volleyball athletes, but the circuit training showed a more effective result compared to the tabata training. The study concludes that both of the training models have positive effects on increasing endurance of volleyball athletes, but the circuit training model has a more effective influence on increasing endurance.

In addition, training high-intensity functions increased Brain-derived neurotrophic factors (BDNF) that caused the development in cognitive performance in attention, executive functions, cognitive flexibility, and working memory (Yarrow et al., 2010). Furthermore, Strategy game play in handball consists in remembering movements and deviations, and in associating them to visual landmarks or to experienced events, and to draw a mental map of the environment that can help to improve cognitive flexibility and executive function (Di Tore, 2016;Kiss & Balogh, 2019) Moreover, high-intensity functional training programs can increase Intrinsic motivation and improve muscle function and the cardiovascular system (Wilke et al., 2019;Menz et al., 2019). Therefore, the experimental group in the part of attention, executive functions, cognitive flexibility, and working memory more than the control group and was related to improve the achievement of sports skills in the experimental group. ...

    This research aims to develop cognitive performance on the success of sports skills in physical education in Buriram Province. The sample group of 80 people was divided into 2 groups of 40 people each. The control group was taught a regular strategy of handball instruction. The experimental group was taught a strategy of handball instruction with high-intensity functional training. Both groups were taught for 1 hour per week according to the normal teaching schedule of the school for a period of 8 weeks. All students were assessed by a computerized cognitive test battery and Sports skills achievement test in pre- and post-experimental. Analysis of the research data was performed by testing differences between the groups using the parametric and non-parametric statistics. After 8 weeks of the experiment, analysis of the difference between the experimental group and the control group in the experimental data was carried out showing that the cognitive performance in terms of attention, executive function, cognitive flexibility, and working memory takes less time in the experimental group than in the control group, including Sports skills achievement scores in the test where the experimental group had more scores than the control group, which is statistically significant at .05. Conclusions. High-intensity functional with strategy sports training program in physical education class can develop cognitive performance in terms of attention, executive functions, cognitive flexibility, and working memory in high school students.

    Background and Study Aim. Basketball involves skills that must be applied dynamically, explosively and repeatedly. Players must be able to speed up and slow down with control, especially when dribbling, shooting or bouncing the ball. The purpose of the study was to test a circuit training-based physical condition training model to increase speed, agility, arm power, and leg muscle power for basketball athletes. Materials and Methods. This type of research is an experiment with two groups, namely the experimental group (n = 28) and the control group (n = 28). The samples were male athletes aged 15-18 years. Subjects had participated in competitions and all players were healthy with no history of illness or injury reported in the previous 3 months. The instruments were 20-meter running test speed, agility (Illinois Test with Dribbling the Ball), arm power (MEDBALL), and leg power (Counter Movement Jump Test). The data analysis technique was a t-test. Results. The results of the study can be concluded that the circuit training-based physical condition training model consisting of 6 posts, is effective for increasing speed (0.017 < 0.05), agility (0.000 < 0.05), arm power (0.000 < 0.05), and leg muscle power (0.036 < 0.05) of basketball athletes. We recommend that basketball coaches consider incorporating a circuit training-based physical condition training model in training, as a simple and practical model to improve athletes' physical condition. Conclusions. We recommend that basketball coaches consider including a circuit training-based physical condition training model in training, as a simple and practical model for improving athletes' physical condition. For researchers who intend to continue or replicate this study, it is recommended to conduct tighter control in the entire series of experiments.

    This study explored the relationship between university students' exercise efficacy and behavioral intention to participate in winter sports. Using a self-efficacy scale, exercise motivation scale, satisfaction with life scale, and the theory of planned behavior questionnaire, the intentions and behaviors of 862 university students were investigated. Based on the Health Action Process Approach (HAPA) model and customer satisfaction theories, a model of the relationship between university students' exercise efficacy and behavioral intention was constructed. The results showed that there was a significantly positive correlation between sports efficacy, motivation, satisfaction, experience perception, and behavioral intention. Sports efficacy had a direct and positive effect on university students' behavioral intention to participate in winter sports (SE = 0.052, Z = 10.673 > 1.96, P = 0.000); The indirect effect of sports efficacy on behavioral intention via motivation and satisfaction was 0.077 (SE = 0.016, Z = 4.813 > 1.96, P = 0.000); the indirect effect of sports efficacy on behavioral intention via experience perception, motivation, and satisfaction was 0.037 (SE = 0.009, Z = 4.111 > 1.96, P = 0.000). Our results not only verify and expand on the HAPA and customer satisfaction theories but also highlight the need for interventions targeting university students' behavioral intention of participating in winter sports from the perspective of improving their sports efficacy, improving the perception of winter sports participation experience, and enhancing their motivation for engaging in exercise and satisfaction with exercise.

    Many observations have demonstrated great heterogeneity in the magnitude of the response to the physical exercise stimulus. Only a few studies have investigated the effects of high-intensity interval training (HIIT) on the prevalence of non-responders (NRs) in adolescents while considering health-related fitness measurements and other co-variables. Therefore, the aim of the current work was twofold: (1) to assess the effects of ten weeks of school-based HIIT on the prevalence of responders (Rs) and NRs for body composition, resting blood pressure (BP), cardiorespiratory and musculoskeletal fitness, and (2) to assess the relationship of this prevalence with sex, body mass category, and biological maturation status, while estimating the likelihood of a response. Adolescents aged 16 years (n = 73) were included in the study. Waist-to-hip ratio, body fat percentage (BFP), skeletal muscle mass (SMM), BP, cardiorespiratory fitness (CRF), and musculoskeletal fitness were the primary outcomes. Co-variables included sex, body mass index (BMI), and maturity offset. The percentages of the Rs and NRs were analyzed based on changes (Δ) between post-intervention and pre-intervention values. The typical error (TE) method was used to identify Rs and NRs. Results showed a variation in the relative size of changes (% of changes) depending on the variable and sex. The greatest changes were observed in females’ abdomen muscle strength (Δ% = 23.89%), and the difference from that of males (Δ% = 5.98%) was statistically significant (p < 0.001) with very large effect size of (Cohen’s d = 0.941). Similar significant differences in relative changes were observed in body composition, but in the reverse direction. Males gained more from HIIT in the decrease in the body fat percentage (Δ% = −8.24%) and increase in skeletal muscle mass (Δ% = 3.38%) comparing to females (Δ% = 0.46, p = 0.040 and Δ% = 1.06%, p = 0.007, respectively). Effect size for body fat was small (Cohen’s d = 0.469), and for skeletal muscle mass it was moderate (Cohen’s d = −0.659). The results also showed positive significant differences in the prevalence of Rs compared to NRs in BFP, SMM, systolic BP (SBP), diastolic BP (DBP), CRF, and abdominal muscular strength (ABS) (p = 0.047, p = 0.047, p < 0.001, p = 0.003, p = 0.014, and p = 0.014, respectively). The effect was greatest and largest for SBP (Cohen’s ω = 0.67). Sex was related to the prevalence of Rs for ABS and close to significance for SMM. More males than females benefited from HIIT in SMM (p = 0.058), but more females than males had ABS benefits (p = 0.050). Males were more likely (2.5-fold) to be Rs than females in SMM. BMI was not related to the prevalence of Rs and NRs. Biological maturation was related to the prevalence of Rs and NRs in SMM (p = 0.036) and SBP (p = 0.016). In SBP, 100% of the early matured derived benefit from HIIT, but the effect size was small (Cramer’s V = 0.27). Those who maturated later were more likely (almost 70%) to be Rs. Thus, the HIIT program introduced to a typical physical education (PE) lesson can be considered partially effective. Therefore, there is a need to continue the search for an optimal and effective program for all health-related parameters. The close relationship between analyzed values and sex and biological maturation, but not BMI, indicates that the intervention programs should be tailored specifically for males and females.

    Previous studies indicated different acute adaptations between obese and lean individuals, while there is limited information with conflicting results regarding long-term adaptations. The aim of this study was to compare the efficacy of a 3-month integrated combined training between obese and lean middle-aged untrained premenopausal women. In total, 72 women (36 obese/36 lean) were divided into four groups: (a) obese exercise (OB-EG), (b) obese control (OB-CG), (c) lean exercise (L-EG), and (d) lean control (L-CG). The exercise groups followed a 3-month (3 times/week) integrated combined aerobic and strength training program. Health indices (body composition, body circumferences, blood pressure, respiratory function), functional capacity (flexibility, balance), and physical fitness (strength, aerobic capacity) were measured before and after the 3-month time period. Participants’ enjoyment was also assessed following the program. OB-EG and L-EG significantly improved (p < 0.05) similarly across all functional capacity and physical fitness indices (10–76%; depending on the evaluation index), except balance and strength indices of the non-preferred limb where OB-EG showed greater improvement (reducing the existing pre-training strength/balance asymmetries) than L-EG. Furthermore, both obese and lean individuals showed similarly high levels of enjoyment. This program could be effectively used in fitness settings causing similar neuromuscular and cardiovascular adaptations in obese and lean women.

    Background/objective: Bodyweight exercises performed at home could be a complementary approach to improve health-related fitness in people having little spare time and during stay-at-home periods. This study then investigated body composition, cardiorespiratory fitness, and neuromuscular adaptations to a home-based, video-directed, whole-body high-intensity interval training (WB-HIIT). Methods: Fourteen subjects participated to an 8-week WB-HIIT (6 females, 23 ± 1 years) and fourteen were included in a non-exercise control group (CTL; 6 females, 24 ± 4 years). All took part to pre- and post-intervention assessments of body composition, peak oxygen uptake (VO2peak) and first ventilatory threshold (VT1; index of aerobic capacity), dynamic (leg press 3-repetition maximum) and isometric strength (knee extensors maximal isometric contractions with assessment of voluntary activation), and muscle endurance during an isometric submaximal contraction maintained till exhaustion. WB-HIIT consisted in 30-s all-out whole-body exercises interspaced with 30 s of active recovery. Training sessions were performed at home by means of videos with demonstration of exercises. Heart rate was monitored during sessions. Results: WB-HIIT increased VO2peak (5%), VT1 (20%), leg lean mass (3%), dynamic (13%) and isometric strength (6%), and muscle endurance (28%; p < 0.05), while they did not improve in CTL. VO2peak increase was correlated (r = 0.56; p < 0.05) with the time spent above 80% of maximal heart rate during training sessions. Isometric strength increase was correlated with change in voluntary activation (r = 0.74; p < 0.01). Conclusion: The home-based WB-HIIT induced concomitant cardiorespiratory fitness and neuromuscular improvements. The predominant effect was observed for aerobic capacity and muscle endurance which could improve exercise tolerance and reduce fatigability.
    ... This divergence from the typical increase in push-up performance could be explained by smaller sample size (n = 7), or the fact that their training sessions were unsupervised [15]. In other populations, there is evidence that HIFT/MM-HIIT increased squat endurance performance [20], sit-up performance [39,40], bench press repetitions with submaximal loads [39,40], and time-to-exhaustion during cardiovascular tasks [40]. Thus, HIFT/MM-HIIT can be used to increase muscular endurance for training academies and beyond, which may ultimately have a positive effect on firefighting performance [41]. ...

    Background: Firefighters typically undergo a 16-24-week training academy during which they perform a variety of traditional exercise programs such as cardiovascular, resistance, and concurrent training. Because of limited facility access, some fire departments seek alternative exercise programs, such as multimodal high-intensity interval training (MM-HIIT), which essentially combines resistance and interval training. Objective: The primary purpose of this study was to assess the effect of MM-HIIT on body composition and physical fitness in firefighter recruits who completed a training academy during the coronavirus (COVID-19) pandemic. A secondary purpose was to compare the effects of MM-HIIT to previous training academies that implemented traditional exercise programs. Methods: Healthy and recreationally-trained recruits (n = 12) participated in 2-3 days/week of MM-HIIT for 12 weeks and had several components of body composition and physical fitness measured before and after the program. Because of COVID-19-related gym closures, all MM-HIIT sessions were performed outdoors at a fire station with minimal equipment. These data were retroactively compared to a control group (CG) that previously completed training academies with traditional exercise programs. Results: Subjects in the MM-HIIT group significantly improved several components of body composition and fitness, including fat mass, fat-free mass, body fat percentage, aerobic capacity, and muscular endurance (p < 0.005). Moreover, there were no significant differences for any dependent variable when MM-HIIT was compared to the CG (p≥0.005). Conclusion: These results suggest that MM-HIIT may serve as an effective substitute for traditional concurrent training paradigms that are typically used for firefighter academies.
    ... Nevertheless, studies that apply circuit training are seldom conducted in ID individuals as compared to normal individuals. Interestingly, it is acknowledged that the circuit training does not only give positive effects to physical fitness, but it is also enjoyable, thus, it may enhance individuals' motivation and interest to do exercise (Wilke et al. 2019). Moreover, circuit training can be adopted as an essential part of physical training, rather than assigning similar training programme that might lead to boredom. ...

    Participation in exercise benefits health and fitness among Intellectual Disability (ID) individuals. Circuit training is one of the exercise programme that can be tailored by manipulating the intensity, time and types of exercise. The purpose of the present study is to examine the effects of six weeks of circuit training on anaerobic fitness and simple reaction time in ID individuals. Thirty participants with mild to moderate ID were selected from individuals who are registered with the Pusat Pemulihan dalam Komuniti (PDK) and Yayasan Orang Kurang Upaya (YOKUK) in the Kelantan state. Participants were randomly divided into Circuit Training and Control groups. Participants in Circuit Training group followed a circuit training exercise programme, two times per week for six weeks, whereas participants in Control group were not involved in circuit training and carried out their regular activities. The anaerobic peak power was significantly decreased (. < 0.001) in Control group after six weeks. The anaerobic power of post-test was significantly improved (p = 0.042) from the pre-test in Circuit Training group and it was also significantly higher (p = 0.001) than Control group. There were no significant differences for the anaerobic capacity and simple reaction time between and within groups. Circuit training can be conducted to enhance anaerobic power in ID individuals, however longer participation may be needed to improve anaerobic capacity and simple reaction time.
