“…Regarding the location of these studies, it was identified that the Southern and Southeastern regions of Brazil were those that most published articles on MS in children and adolescents, with 18 studies 7-9,12-27 . Regarding the design of included studies, 22 had cross-sectional 3,7-9,14-21, [23][24][25][27][28][29][30][31][32][33][34][35] and five longitudinal design 12,13,22,26,36 (Table 1). The studies covered different primary goals as can be observed in Table 1; however, all of them performed MS measurements as defined in the present study.…”

HJ was used to identify MS levels in 16 studies 12,13,15,16,[19][20][21]23,27,[29][30][31][32][33]35,36 ; in 15 studies, MS was investigated through HGS 3,8,9,12,15,17,20,22,[24][25][26]28,33,35,36 ; in four studies, vertical jump without the aid of arms (VJWAA) was used to evaluate MS 12,20,22,26 ; in four other studies, TMB was used 16,23,29,30 ; in two studies the isokinetic strength of knee extensors (IFKE) was used as a reference for MS 14,21 ; in two other studies, MS was investigated through vertical jump using arms (VJUA) 14,21 ; the maximal repetition in the horizontal bench press (1MRBP) and a maximal repetition in the leg press (1MRLP) tests were used to measure MS levels in one study 7 ; the tests of a maximal repetition in the extensor table (1MRET) and a maximum repetition in the biceps curl (1MRBC) thread were used in another study…”

Muscle strength (MS) is considered important indicative of global health regardless of age or clinical condition. The aim of this study was to summarize evidence from research carried out in Brazil that investigated MS in school children and adolescents, showing the objectives, tests, protocols and quantitative of youngsters who met the health criteria for MS. Systematic review conducted in the PubMed, Web of Science, Scopus, Sportdiscus, LILACS and Scielo databases, with complementary searches in reference lists. In all articles, the risk of bias was analyzed. Of the 15,609 articles initially identified, 27 were included, comprising data from 29,604 children and adolescents. The 27 studies included presented moderate (37%) and low risk of bias (63%). Three out of four studies investigating MS in children and adolescents were carried out in southern and southeastern Brazil (77.7%). It was found that 65.9% of boys and 58.2% of girls had adequate levels of MS for health, with results varying from 14.8% to 66.0% in girls and from 20.4% to 76.9% in boys. Several MS measurement protocols were identified; however, horizontal jump was the most used test to evaluate MS (59.2%). MS is a physical valence searched in children and adolescents and a variety of protocols are used. In addition, it is necessary to propose MS cutoff points based on health criteria for the accurate estimation of this physical valence in children and adolescents in Brazil.

“…An analysis for a proxy measure of "muscle fiber ratio" 26 was estimated by calculating the ratio of myosin 7 (MYH7), the slow-twitch fiber isoform, and the sum of fast-twitch fiber isoforms (MYH1, MYH2 and MYH4) ( Figure S2A1-A4); as expected, the fiber ratio of slow/fast was higher with older age ( Figure S2A5). The slight change of slow/fast fiber ratio was significant and outweighed the wide variability among individuals (p=0.005); BMI was adjusted because obese persons tend to have muscle fat infiltration and lower muscle quality and muscle-fat interaction may affect muscle composition and function 4,27 . Gender may also have an impact on protein expression in skeletal muscle, as males and females are known to have differences in muscle mass; however, because of the limited sample size, we did not stratify the analysis by gender.…”

A progressive decline of skeletal muscle strength with aging is a primary cause of mobility loss and frailty in older persons, but the molecular mechanisms of such decline are not fully understood. Here, using quantitative discovery proteomic data from skeletal muscle specimens collected from 58 healthy persons aged 20 to 87 years show that ribosomal proteins and proteins related to energetic metabolism, including those related to the TCA cycle, mitochondria respiration, and glycolysis were underrepresented in older persons.Proteins with important roles in innate and adaptive immunity, involved in proteostasis and regulation of alternative splicing were all overrepresented in muscle from older persons.Changes with aging of alternative splicing were confirmed by RNA-seq. Overall, older muscle has a profound deficit of energetic metabolism, a pro-inflammatory environment and increased proteostasis. Upregulation of the splicing machinery maybe an attempt to compensate for these changes and this could be tested in future studies. 20 30 40 50 60 70 80 −0.4 0.0 0.2 0.4 r 2 = 0.05, p = 0.13872 Figure 7Supplemental Information Aging Skeletal Muscle Proteomics Finds Changes in Spliceosome, Immune factors, Proteostasis and Mitochondria

“…The increase in the time spent in sedentary behaviors is another aspect that can directly contribute to body fat accumulation due to the reduction of energy expenditure 2 , and loss of tone and muscular volume, resulting in the reduction of strength levels 2,14 . Several studies have investigated the relationship of muscular strength in adolescents according to sexual maturation; however, much of the content described in literature refers to strength performance in the upper limbs [15][16][17] and abdomen 15 . In addition, information regarding lumbar force in adolescents is scarce 8 , although greater knowledge regarding lumbar force could help in the early diagnosis of health problems related to lower levels of lumbar force, such as musculoskeletal pain and postural deviations 8. Thus, the aim of this study was to compare the performance of the lumbar force test between pubertal and post-pubertal adolescents by controlling the interference of physical growth, body fat, screen time and physical activity.…”

-Aim:To compare performance in the lumbar force test in pubertal and post-pubertal adolescents by controlling the interference of physical growth, body fat, screen time and physical activity. Methods: A cross-sectional study with 933 adolescents (492 girls) aged 14-19 from the city of São José, Brazil. Lumbar strength was assessed using the isometric lumbar extension test proposed by the Canadian Society of Exercise Physiology. Sexual maturation was classified according to Tanner's criteria. Physical growth variables (age, body weight, stature, BMI), body fat (triceps and subscapular skinfolds), sedentary behavior based on screen time and overall physical activity were controlled in the Analysis of Covariance (ANCOVA), with a significance level of 5%. Results: Post-pubertal boys presented higher lumbar force compared to pubertal ones only when interference of BMI, body fat, screen time and physical activity was controlled. Pubertal girls presented higher lumbar force compared to post-pubertal ones, both when controlling the analysis for the studied variables and when not controlled by them. Conclusion: BMI, body fat, screen time and physical activity interfere in the difference in lumbar strength of boys, in which post-pubertal boys presented better performance in lumbar force compared to pubertal ones. Regardless of interference or not of these variables, pubertal girls presented better performance in lumbar force when compared to post-pubertal ones.
