Influence of Exercise Order on Muscle Damage During Moderate-Intensity Resistance Exercise and Recovery

Abstract

This study aimed to investigate the role of exercise order on total number of repetitions and to evaluate the possible importance on muscle damage and on rating perceived exertion (RPE). Ten trained participants completed two sequences: sequence A (SEQA) was leg press (LP), leg extension (LE), leg curl (LC), bench press (BP), shoulder press (SP), and triceps extension (TE) and in sequence B (SEQB), the order of execution of the exercises was reversed. Highest creatine kinase (CK) concentrations were observed 24 hours following both sessions, but no differences were found at any time between them, revealing that muscle damage has occurred. There were significant differences between SEQA and SEQB in the total number of repetitions for TE, LE, and LC. Our results suggest that differences in total strength production when exercise order is changed must be explained by some other mechanisms besides muscle damage and RPE.

Muscle damage produced during a simulated badminton match in competitive male players

“…Indirect markers of muscle damage (e.g., myoglobin, CK, and LDH) were significantly increased at the end of the simulated 45-min match. The presence of these proteins in the blood is an indication of damage to the muscle cell membrane, which has been noted after several modalities of intensive/ prolonged exercise (Chaves et al, 2013;Del Coso et al, 2012Souglis et al, 2015;Takarada, 2003). Several authors have established a relationship between the increase in blood markers of muscle damage and the decrease in the muscle performance (Byrne et al, 2004;Del Coso et al, 2012.…”

“…The increase in the concentration of the blood proteins is a reflection of what is released by the tissue and what is cleared from the circulation (McKune, Semple, & Peters-Futre, 2012). In the literature most studies that analysed muscle damage after training or competition have used blood myoglobin, CK, and LDH concentrations to detect the presence of muscle injuries produced during exercise because they properly reflect the level of muscle damage produced during exercise and they are easy to assess (Chaves et al, 2013;Majumdar et al, 1997;Takarada, 2003;Yang, 2007).…”

Influência da ordem de execução de exercícios com pesos sobre o volume total de treino quando a carga é ajustada de acordo com a sequência

“…Embora não tenha sido observada diferença significante entre as sequências para o volume total das sessões de treino, quando analisado o volume total de cada exercício, verificaram-se diferenças significantes (P < 0,05) nos exercícios supino reto e tríceps no pulley, sendo que no supino reto o volume foi maior na SEQA, na qual este exercício estava no início da sessão, ao passo que no tríceps no pulley, que estava no meio da sequência, o volume foi menor nesta mesma sequência. A literatura indica que exercícios realizados ao final da sessão podem sofrer influência negativa em comparação ao mesmo exercício realizado no inicio da sessão [4][5][6]8,[12][13][14][15][16] . Entretanto, esta hipótese não foi confirmada na maioria dos exercícios testados no presente estudo.…”

“…Neste sentido, a literatura aponta que a ordem de execução dos exercícios é uma importante variável a ser considerada na prescrição de um programa de TP 1,3 , visto que a adoção de diferentes ordens pode influenciar o número de repetições executadas [4][5][6] , a ativação neuromuscular [7][8][9] , a percepção subjetiva de esforço 10 e algumas respostas hormonais 11 . Assim, alguns pesquisadores advogam que os exercícios representativos dos grupamentos musculares a serem priorizados devem ser realizados no início da sessão de TP, visto que o rendimento dos exercícios posicionados no final do programa de treinamento parece ser afetado negativamente [4][5][6]8,[12][13][14][15][16][17] . Entretanto, ao se analisar os estudos publicados até o presente momento sobre a ordem de execução dos exercícios em programas de TP, observase que as mesmas cargas têm sido aplicadas a cada exercício (cargas fixas), independente da sequência a ser analisada (dos grandes para os pequenos grupos musculares ou vice-versa), desconsiderando a fadiga residual desenvolvida ao longo da sessão de treinamento.…”

Acute Effects of Different Intensities of Resistance Training on Glycemic Fluctuations in Patients With Type 1 Diabetes Mellitus

“…Nevertheless, including resistance training in a physical exercise program for subjects with T1D is recommended for minimizing cardiac risks and increasing muscle strength, and it appears to improve the body's resistance to insulin (Albright et al, 2000). In addition, increasing muscle strength is generally deemed as an important consideration for training programs with the purpose of improving general health, physical fitness, and performance (Chaves et al, 2013).…”
