“…These findings are in accordance with authors who reported greater TRICEP activation with push-ups on a Swiss ball (Lehman et al, 2006) than on the floor. On the other hand, Freeman et al (2006) found no differences between conditions, although the unstable device used in this study consisted of two basketballs that probably lacked the appropriate degree of instability to lead to changes in muscle activation.…”

“…Other studies reported similar DELT activation during push-ups with the hands on two separate balls (Freeman et al, 2006) in comparison with a stable surface. Despite variations in gleno-humeral joint position during the exercise and different instability degrees may change muscle activity results.…”

“…Each subject performed three consecutive repetitions in all conditions. A 2-second rate for descent and ascent of an individual push-up cycle was maintained by a 30-Hz metronome (Ableton Live 6, Ableton AG, Berlin, Germany) to standardize speed of movement (Freeman et al, 2006). Each subject used a standardized grip width of 150% of biacromial width (distance in centimeters between the tips of right and left third digits).…”

“…One possible modification is varying the height of the hands and performing the exercise in unstable conditions. Several authors reported muscle activity changes when they compared unstable pushups with standard floor push-ups (Freeman, Karpowicz, Gray, & McGill, 2006;Lehman, Macmillan, MacIntyre, Chivers, & Fluter, 2006). Lehman et al (2006) discovered that push-ups performed using unstable devices activate the triceps brachii in a greater extent.…”

“…Lehman et al (2006) discovered that push-ups performed using unstable devices activate the triceps brachii in a greater extent. Freeman et al (2006) found that unstable push-ups lead to a higher percentage of maximum voluntary isometric contraction (MVIC) especially for the abdominal wall. Similarly, Marshall and Murphy (2005) found higher rectus abdominis muscle activation during the unstable condition than in the stable condition.…”

This study was designed to analyze upper extremity and core muscle activation performing push-ups under different stability conditions and body positions. Trained university male students (n= 29) performed 3 push-ups each under stable conditions and using suspension device (AirFit Trainer ProTM) with their hands at 2 different heights (i.e., 10 and 65 cm). Push-up speed was controlled using a metronome and the testing order was randomized. The average amplitudes of the electromyographic root mean square of the Triceps Brachii, Upper Trapezius, Anterior Deltoid, Clavicular Pectoralis, Rectus Abdominis, Rectus Femoris, Lumbar Erector Spinae and Gluteus Maximus were recorded and normalized to the maximum voluntary isometric contraction. A repeated-measures analysis of variance with a Bonferroni post hoc test was used to analyze data. Suspended push-ups provided greater activity than the stable condition, except for the Anterior Deltoid and Clavicular Pectoralis. Therefore, suspended push-ups are especially advantageous if the goal of the exercise is targeting the TRICEP, TRAPS and/or core training. Overall, performing push-ups at 65 cm from the floor decreases exercise intensity and muscle activity in comparison with the 10 cm position. Keywords: EMG, suspension training, core, body position RESUMO Este estudo foi realizado com vista a analisar a ativação muscular do tronco e "core" na realização de flexões sob diferentes condições de estabilidade e posições corporais. Estudantes universitários do sexo masculino treinados (n= 29) realizaram três flexões de braços em condições estáveis e em suspensão (AirFit instrutor ProTM) com as mãos em duas alturas diferentes (10 e 65 cm). A velocidade de execução foi controlada usando um metrónomo sendo a ordem dos testes aleatória. A amplitude média da atividade eletromiográfica do Triceps Brachii, Upper Trapezius, Anterior Deltoid, Clavicular Pectoralis, Rectus Abdominis, Rectus Femoris, Lumbar Erector Spinae e Gluteus Maximus foram registados e normalizados tendo por base a contração isométrica máxima. Foi utilizada a análise de variância para medidas repetidas, com o teste de Bonferroni para análise dos dados. Flexões de braços suspensas proporcionam maior atividade muscular do que realizadas em condição de estabilidade, com exceção do Anterior Deltoid e Clavicular Pectoralis. Portanto, flexões de braços suspensas são especialmente vantajosas se o objetivo for o treino dos Triceps Brachii, Upper Trapezius e/ou dos músculos do "core". A realização de flexões a 65 cm do chão diminui a intensidade do exercício e a atividade muscular comparativamente com a posição a 10 cm.
