Correlação do teste de 1RM com aspectos maturacionais, neuromotores, antropométricos e a composição corporal em crianças e adolescentes

Abstract

ABSTRACT1 Repetition Maximum (1RM) tests have been used in research on strength training effects in children and adolescents. However, little is known about the association between 1RM tests and morphologic, neuromotor and biological maturation variables. Therefore, the purpose of the present study was to analyze the relationship between 1MR tests and body composition, anthropometric variables, neuromotor tests and biological maturation. For such purpose, correlational methodology was used. The study involved 10 boys with average age of 10.28 (±2.20) years old. The variables analyzed were: body mass, stature, circumferences, skinfolds and biological maturation (pubic and axillary pilosity and genital development). Hence the sample was submitted to a battery of five neuromotor tests and six 1RM tests sessions for upper (UL) and lower (LL) limbs. Data analysis was developed using the Shapiro-Wilk's test (p≤0.05), descriptive statistics and the Spearman Correlation Coefficient (p< 0.01; P≤ 0.05). A strong correlation between age and the 1RM load for UL and moderate for LL was found. Stature presented a moderate correlation with 1MR of UL and strong correlation for 1RM of LL; absolute lean body mass presented moderate and strong correlation for UL and LL, respectively. The 1RM test for UL presented moderate correlation for pubic hair and strong correlation for axillary pilosity. These results indicated a multifactorial influence in the 1RM test loads demonstrating the importance in the use of morphological aspects, biological maturation and/or chronological age in the results analysis. Considering the weak relationship between the neuromotor and the 1RM tests, although they have been well used in research related to strength training on children and adolescents, their results should be carefully used when the purpose is to get information on the magnitude effects of strength training in that age range.

Diversity of parameters in the muscle strength evaluation of Brazilian school children and adolescents: a systematic review

“…Freitas et al, 35 Montes Claros, MG No study was classified with low methodological quality / high risk of bias. Moderate methodological quality/moderate risk of bias was verified in ten studies (37.0%) 7,12,13,15,19,21,23,26,28,29 , while seventeen studies … continue (67.0%) 3,8,9,14,16,17,20,22,24,25,27,[30][31][32][33]35,36 were classified with high methodological quality / low risk of bias (Table 2). MS was investigated in fourteen different ways.…”

“…MS was investigated in fourteen different ways. 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…”

“…In the present review, 27 studies that investigated MS in children and adolescents were identified, and a large number of these studies were published after 2010 [7][8][9]17,[19][20][21][22][23][24][25][27][28][29][30][31]33,35,36 , demonstrating that the subject has current research in the Brazilian scenario. Although the body of evidence regarding the cardiovascular and metabolic health benefits attributed to MS are unambiguous 4,5 , it is speculated that the contemporary consolidation of recommendations for MS improvement in children and adolescents 1 could justify the recent research relating MS in studies with children and adolescents.…”

Effects of Strength Training on Sleep Parameters of Adolescents: A Randomized Controlled Trial

“…Before beginning the ST program, the adolescents performed a 1RM test to determine exercise workload, as previously recommended (1,11,18). In each exercise, the test was started with a warm-up (10 repetitions), using approximately 50% of the load established for the first 1RM attempt.…”

Effects of exergame training on the health promotion of young adults

“…To evaluate the PMS the following tests were performed: sit and reach test to measure the lexibility of the lower limbs (18); abdominal test to estimate abdominal strength and endurance (19); arm lexion test to assess strength and endurance of the upper limbs (UL) (20); shuttle run test to evaluate the agility and speed (21); and running 50 meters test to analyze the speed of movement (22).…”
