Karate is an ancient martial art practiced by around 100 million people worldwide. In Brazil, it is estimated that approximately 250,000 people practice this modality. However, limited data are available outlining the physical capabilities of these athletes. The purpose was to analyse changes in physical capabilities of muscular strength, power and flexibility in karate athletes during a state championship. Data were collected during a karate state championship. From a total of approximately 200 participating athletes, data were collected from male (n = 34, 19.0 ± 9.84 years, 67.6 ± 21.8 kg, 165 ± 11.2 cm, 24 .3 ± 5.99 kg/m²) and female athletes (n = 12, 16.0 ± 4.47 years, 59.1 ± 11.8 kg, 156 ± 6.35 cm, 24.1 ± 4.35 kg/m²). Measurements: body mass, height, flexibility, handgrip muscular strength and lower limb power were performed before and after competition fights by a team of trained evaluators. Data were analysed between sexes, pre and post-competition, as well as by age group and number of fights performed. After the fights, there was a significant increase in muscular strength (+5.2%, p = .004), with no difference between different age groups (p = .141), sexes (p = .196), and number of fights performed (p = .072). There were no significant changes in muscle power performance (p = .124) and flexibility (p = .241) across fights or between sexes. A karate tournament in which athletes are involved in one to three fights does not seem to impair their performance in terms of muscular strength, power and flexibility, regardless of age, sex and number of fights performed.

Amarante do Nascimento, M, Nunes, JPA, Pina, FLC, Ribeiro, AS, Carneiro, NH, Venturini, D, Barbosa, DS, Mayhew, JL, and Cyrino, ES. Comparison of 2 weekly frequencies of resistance training on muscular strength, body composition, and metabolic biomarkers in resistance-trained older women: Effects of detraining and retraining. J Strength Cond Res 36(5): 1437–1444, 2022—This study aimed to compare the effects of 2 weekly frequencies of resistance training (RT) on muscular strength, body composition, and metabolic biomarkers in previously resistance-trained older women after detraining and retraining. Forty subjects (>60 years) performed RT (8 exercises, 1 set of 10–15 repetitions maximum) 2 (G2x) or 3 (G3x) times per week over 12 weeks of training and retraining. After training, subjects were detrained for 12 weeks. After detraining, there were significant decreases (p < 0.05) in upper-body (∼12%) and lower-body (∼14%) muscular strength, fat-free mass (FFM) (∼2%), and testosterone (∼26%), whereas increases were revealed for fat mass (FM) (∼4%), relative body fat (∼3%), fasting glucose (∼8%), low-density lipoprotein cholesterol (LDL-C) (∼21%), and triglycerides (∼24%), with no differences between groups (p > 0.05). Following retraining, there were significant increases (p < 0.05) for upper (∼7%) and lower (∼10%) muscular strength, FFM (∼2%), and testosterone (∼20%). In contrast, decreases were found for FM (∼7%), relative body fat (∼3%), fasting glucose (∼6%), LDL-C (∼14%), and triglycerides (∼21%), also with no differences between groups (p > 0.05). Gains after retraining were lower than after training (p < 0.05) only for upper- and lower-body muscular strength (∼6%) and testosterone (∼11%). Total cholesterol, high-density lipoprotein cholesterol, IGF-1, and C-reactive protein did not change at any point in the study for either group (p > 0.05). Our results suggest that older women can regain previous RT program benefits following detraining, regardless of the weekly training frequency. However, some fitness components may take longer to reestablish than the initial training level. [ABSTRACT FROM AUTHOR]

This study aimed to analyze whether the frequency and duration of physical activity and sedentary behavior interfere with the risk of sarcopenia in elderly attending social groups. Cross-sectional study to evaluate 207 elderly people attending social groups in the municipality of Sarandi, state of Paraná. The International Physical Activity Questionnaire (IPAQ) and the SARC-F were used. Data were analyzed using inferential statistics (p<0.05). The prevalence of elderly people with active level of physical activity (93.2%) and no risk of sarcopenia (75.8%) was observed. Elderly people at risk of sarcopenia spend more time sitting on weekdays than elderly people with no risk of sarcopenia (p=0.043). Duration and frequency of physical activity do not affect the risk of sarcopenia. However, the risk of sarcopenia is associated with sedentary behavior of the elderly. [ABSTRACT FROM AUTHOR]

Objective: To investigate the difference in the proportion of students with metabolic syndrome, diagnosed according to different criteria. Methods: The sample consisted of 241 students (136 boys and 105 girls) aged 10 to 14 years, from public and private schools in Paranavaí, Paraná. We used three distinct diagnostic criteria for metabolic syndrome, considering the presence of at least three of the following risk factors: increased waist circumference, hypertension, fasting hyperglycemia, low HDLC, and elevated triglycerides. Results: The prevalence of metabolic syndrome found was 1.7% (confidence interval of 95% – 95%CI 0–3.3) for the IDF criterion; 3.3% (95%CI 1.0–5.6) for Cook; and 17.4% (95%CI 12.6–22.3) for Ferranti. Analyzing the criteria in pairs, the agreement between IDF and Cook was 97.5% (k=0.95); between IDF and Ferranti, 83.4% (k=0.67); and between Cook and Ferranti, 85.9% (k=0.72). Only one student (0.4%) was diagnosed with metabolic syndrome solely by the IDF criterion, while 34 (14.1%) were diagnosed exclusively by Ferranti. The comparison of the three criteria showed that Ferranti presented the highest proportion of metabolic syndrome (p<0.001), and Cook had a greater proportion than IDF (p<0.001). Conclusions: We found a significant difference in the proportion of metabolic syndrome in the three criteria. The choice of which criterion to use can compromise not only the percentage of metabolic syndrome prevalence but also interfere in strategies of intervention and prevention in children and adolescents with and without metabolic syndrome, respectively.
