Background: This study aims to assess the effects of 8 weeks of plyometric jump training (PJT) conducted on sand or a rigid court surface on jump-related biomechanical variables and physical fitness in female indoor volleyball players. Methods: Seventeen participants were randomly divided into a sand surface group (SsG, n = 8) and rigid surface group (RsG, n = 9). Both groups completed equal indoor volleyball training routines. Participants were assessed pre and post the 8-week PJT for jump-related biomechanical variables (countermovement jump (CMJ) RSI; drop jump (DJ) reactive strength index (RSI); spike jump (SJ) height; CMJ height; CMJ rate of force development (RFD); CMJ velocity at take-off; DJ height and CMJ peak force), 20 m linear sprint time, t test for change-of-direction sprint (CODs) time, Wingate test peak power (PP), cardiorespiratory endurance, and leg-press one-repetition maximum (1RM). Results: A two-way mixed analysis of variance (group × time) revealed that there was a significant group × time interaction between DJ height (p = 0.035) and CMJ peak force (p = 0.032) in favour of RsG and SsG, respectively. A significant interaction was also observed for cardiorespiratory endurance (p = 0.01) and 1RM (p = 0.002), both favouring the SsG. No other group × time interaction was observed. Conclusions: The type of surface used during PJT induced specific adaptations in terms of jump-related biomechanical variables and physical fitness in female indoor volleyball players. Based on the individual needs of the athletes, practitioners may prescribe one type of surface preferentially over another to maximize the benefits derived from PJT.

The current research aimed to incorporate appropriate circuit resistant training protocol in the current literature and device that could help improve cardio-respiratory endurance of soccer players.  A pre-test and post-test longitudinal research format was applied because the suggested parameters of cardiorespiratory endurance were appropriately calculated by such research designs. A sample of (n=40) healthy volunteers equally distributed into two different groups namely, an experimental group (EG) and a control group (CG). The circuit resistant training (CRT) 3 times per week with specified intensity, repetition, set and rest period continued for 06 weeks among experimental group. Results of the analyzed data revealed a significant increase in the cardiorespiratory indices (CO, SV, IRV, ERV) among the participants of experimental group (p < .05). These results tend to interpret that cardiorespiratory fitness of soccer’s players can be improved with the help of 06 week (CRT) program. Apart from this, health and physical education teachers, physiotherapists and other relevant persons can recommend CRT for lifestyles improvement.

We investigated whether a 1-week stay in the mountains may have a positive impact on Exercise-Induced Bronchoconstriction (EIB) and cardiorespiratory endurance in asthmatic children from an urban area. Spirometry was performed before and 10 min after a 20 m shuttle run test (20mSRT) on the first and seventh day of a summer asthma camp in the Italian Alps at 900 m of altitude. Spirometry z-scores were derived from the Global Lung Initiative 2012 prediction equations, and percentiles of the 20mSRT performance were assigned according to De Miguel-Etayo’s and Tomkinson’s predictive equations. A FEV1 decrease ≥10% after the exercise was defined as EIB. Particulate matter pollution was monitored during the camp and in the urban area of provenience. Twenty-four subjects (age range 7–16 years) were included. Frequency of EIB decreased from 58% (14/24) at day-1 to 33% (8/24) at the end of the camp (p = 0.08). Most subjects with a 20mSRT in the lowest quartile at day 1 had EIB (9/11). The proportion of children with a 20mSRT <25° percentile decreased from 45% (11/24) at day-1 to 16% (4/24) at day-7 (p = 0.02). Conclusion: One-week climate therapy in the mountains improved both bronchial hyperreactivity and cardiorespiratory endurance in our cohort of asthmatic children.

The purpose of this study was to meta-analyze the effects of yoga intervention on physical fitness in the elderly. The following databases were systematically searched in 25 March 2021: Cochrane, PubMed and Embase. A total of 656 papers was identified through key word combinations, finally, 12 studies were included in the meta-analysis. The main conclusions are as follows. First, yoga practice showed moderately positive effects on muscle strength, balance, mobility, and lower body flexibility, but had no significant effect on cardiorespiratory endurance and upper body flexibility. Second, sub-group analysis showed that subjects in their 60s and 70s and yoga practice for 9–12 weeks had a large positive effect on physical fitness. Yoga is a multimodal activity that improves muscle strength, balance, and flexibility in the elderly, and physical activity policies should continue to promote yoga as an activity that enhances physical and mental wellbeing in this population.

Abstract Background Physical fitness is an essential marker of health. The literature regarding the question of whether individuals with asthma have reduced physical fitness compared to their non-asthmatic peers is inconsistent and focuses on the cardiorespiratory endurance dimension. This study provides a comparison of different dimensions of physical fitness in individuals with and without asthma on the basis of the German population-based study “KiGGS” (German Health Interview and Examination Survey for Children and Adolescents) and its in-depth study “MoMo” (2009–2012: wave 1 and 2014–2017: wave 2). Methods In total, 7731 individuals aged 6–30 years were included in this cross-sectional analysis at two measurement waves, including 353 individuals with and 7378 without asthma. The 12-month prevalence of physician-diagnosed asthma was assessed by interview. Physical fitness was measured by six test items of the MoMo test profile. “Cardiorespiratory endurance” was measured by an ergometric test, “muscular strength” by standing long jump, push-ups and sit-ups and “coordination” by jumping sideways and balancing backwards. Because of the broad age range of the sample, age- and sex-specific percentiles were used. Physical activity, age, gender and general state of health were assessed by questionnaire. Results The individuals with asthma reported a poorer general state of health at both measurement waves. However, the results of the fitness tests indicated that they were as physically fit as their peers without asthma in relation to cardiorespiratory endurance and muscular strength. The mean percentiles were all within the same range. The results of the comparisons of coordination performance were inconsistent. At wave 1 they were within the same range, at wave 2 individuals with asthma showed a poorer coordination performance (p = 0.041; HL = 4.125, CI of HL 0.155–8.125). Conclusions To the best of our knowledge, this is the first study to compare the physical fitness of individuals with and without asthma by considering several dimensions of physical fitness. The study demonstrates that cardiorespiratory endurance and muscular strength are not reduced in individuals with asthma. The results of the comparisons at the two measurement waves were remarkably stable.

This narrative review evaluates strength or resistance training on cardiorespiratory endurance, blood pressure, contractile function, contractile protein synthesis rate, bone turnover, gait and balance, and neuromuscular adaptations in elderly populations. Seventy-eight studies spanning from 1999 through 2020 were reviewed. Database sources including PubMed, Science Direct, Web of Knowledge and Google Scholar were searched in accordance with the purpose of the study. A majority of the studies reported that resistance training reduces blood pressure and increases contractile functions, contractile protein synthesis rate, bone turnover, gait and balance, cardiorespiratory endurance, and neuromuscular adaptations in the elderly. Furthermore, combined training (CT), also known as concurrent training (strength plus endurance training) may also be as effective as traditional endurance training or traditional strength/resistance training alone for improving cardiorespiratory endurance and functional performance. According to the evaluation of studies included in this review, we concluded that training modalities that involve low-load, high velocity strength training combined with endurance training might be the best training strategy in improving cardiovascular fitness, functional capacity and musculoskeletal health in the elderly populations. Elderly people should be encouraged to participate in a concurrent training or a combination of strength and endurance training to delay, or even reverse the negative effects of aging. <p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0875/a.php" alt="Hit counter" /></p>

This study aims to determine the effect of skipping combination with body weight training on cardiorespiratory endurance and BMI as an effort to prevent Covid 19 for overweight adolescents. This research is an experimental research. In this study, treatment was given in the form of skipping exercise combined with body weight training for 8 weeks with a frequency of 3 times / week, an intensity of 60%-70% MHR with a duration of 30 minutes. The population in this study were teenagers. Sampling was done by purposive sampling on adolescents aged between 17-21 years and overweight. Instrument used to measure VO2 max with MFT (multistage fitness test) and measurement of height and weight to determine BMI. The data analysis technique used prerequisite test and paired t test. Based on the results of the cardiorespiratory endurance data analysis, the t-count value was 10.495 with a significance value of 0.000, it can be concluded that there is a significant effect of skipping combination with body weight training on cardiorespiratory endurance in overweight adolescents. The mean value of the cardiorespiratory endurance pretest was 34.92 and the posttest average increased to 40.05. While the results of the analysis on BMI data obtained a t-count value of 15.293 with a significance value of 0.000, it can be concluded that there is a significant effect of skipping combination with body weight training on BMI in overweight adolescents. The mean value of the BMI pretest was 26.60 and the posttest average BMI decreased to 22.19. So it can be concluded that skipping exercises combined with body weight training can increase cardiorespiratory endurance and reduce BMI as an effort to prevent Covid 19 for overweight adolescents.

Abstract Cricket-bowling performance is known to be influenced by speed of ball release and accuracy. Currently, training sessions typically involve fielding-specific drills and conditioning exercises. Scientific evidence for inclusion of a comprehensive yoga intervention in daily training and exercise sessions remains unexplored. The present study explored the effect of yoga on bowling performance and physical fitness in cricket bowlers. Sports fitness testing and training were conducted among 60 non-elite recreational-club male cricket players aged 13–25 years. Cricket-bowling speed was e valuated using a speed radar gun, accuracy with a test developed by Portus et al., cardiorespiratory endurance using the yo-yo intermittent recovery test, lower-extremity and trunk strength using a back-leg dynamometer, upper-limb power using a medicine ball–throw test, power using a vertical-jump test, and flexibility using a sit-and-reach test. In addition to bowling practice, the yoga intervention group (n = 30) performed pranayama and standing and prone asana, whereas the control group (n = 30) practiced conventional conditioning exercises, for 45 minutes/day, three times a week, for 12 weeks. Improvement in bowling speed, accuracy, cardiorespiratory endurance, muscle strength, and flexibility were comparable between the two groups. Statistically significant improvements in baseline scores in bowling speed, accuracy, cardiorespiratory endurance, muscle flexibility, strength, and power were comparable between the two groups of non-elite male cricket players. Bowling speed improved by 6.52% in the yoga group and by 5.18% in the control group. Bowling accuracy improved by 35.40% in the yoga group and by 31.29% in the control group. Additional research on long-duration intervention in elite players may help to establish the role of yoga in conventional cricket-bowling training.
