PURPOSE This study was conducted to quantify the normalized amplitudes of the abdominal wall and back extensor musculature during a variety of push-up styles. We also sought to quantify their impact on spinal loading by calculating spinal compression and torque generation in the L4-5 area. METHODS Ten university-age participants, nine males and one female, in good to excellent condition, volunteered to participate in this study. All participants were requested to perform a maximum of 12… Expand
Abdominal muscles dominate contributions to vertebral joint stiffness during the push-up.
TLDR
The goal of this study was to quantify the relative contributions of each muscle group surrounding the spine to vertebral joint rotational stiffness (VJRS) during the push-up exercise to suggest the orientation of the abdominal muscles suggests that each muscle primarily controls theRotational stiffness about a single axis. Expand
Muscular contribution to low-back loading and stiffness during standard and suspended push-ups.
TLDR
Compared to the standard version of the exercise, suspended push-ups appear to provide a superior abdominal muscle challenge, however, for individuals unable to tolerate high lumbar IVJ compressive loads, potential benefits gained by incorporating suspended Push-ups into their resistance training regimen may be outweighed by the risk of overloading low-back tissues. Expand
Muscle Activation during Push-Ups with Different Suspension Training Systems.
TLDR
A one-anchor system with a pulley is the best option to increase TRICEP, TRAPS, LUMB and FEM muscle activity and more stable conditions such as the standard push-up or a parallel band system provide greater increases in DELT and PEC muscle activation. Expand
Muscle activation differences between stable push-ups and push-ups with a unilateral v-shaped suspension system at different heights
TLDR
Overall, performing push-ups at 65 cm from the floor decreases exercise intensity and muscle activity in comparison with the 10 cm position, therefore, suspended push-up are especially advantageous if the goal of the exercise is targeting the TRICEP, TRAPS and/or core training. Expand
Selective Activation of Shoulder, Trunk, and Arm Muscles: A Comparative Analysis of Different Push-Up Variants.
TLDR
The narrow-base variant to emphasize triceps and pectoralis activity and the BP variant for total upper body strength conditioning should be implemented carefully in participants with low back pain because of the greater activation of abdominal and back muscles. Expand
Muscle Activity Levels in Upper-Body Push Exercises With Different Loads and Stability Conditions
TLDR
Elastic-resisted push-ups induce similar EMG stimulus in the prime movers as the bench press at high loads while also providing a greater core challenge. Expand

TLDR
Stable push-ups elicit similar PEC and higher DELT muscle activation, being greater at 10 cm; whereas suspended push-up elicit greater TRAPS and TRICEP muscle activation at 65 cm, which determines different muscle activation patterns. Expand
Muscular activities during sling- and ground-based push-up exercise
TLDR
Results supported the hypothesis and indicate that sling-based push-up exercise can provide greater activation in upper limb and anterior trunk muscles than the ground-based Push-up Exercise. Expand
Comparison of Scapular Stabilizer and External Oblique Abdominis Muscle Activity on Push-up
TLDR
The results suggest that QP push-up plus exercise can be a very useful to improve safety and to selectively train serratus anterior for patients with shoulder instability for the future. Expand
Muscle activation during push-ups performed under stable and unstable conditions.
TLDR
Not all unstable devices enhance muscle activation compared to traditional push-ups, and the suspended device was the only condition that elicited higher LUMB and FEMactivation compared to the other conditions. Expand

TLDR
The relatively low levels of normalized myoelectric activity during maximal twisting efforts coupled with large levels of agonist–antagonist cocontraction caused the model to severely underpredict measured torques, which suggests that stabilization of the joints during twisting is far more important to the iumbar spine than production of large amounts of axial torque.

Mechanical stability of the in vivo lumbar spine: implications for injury and chronic low back pain.
TLDR
It appears that there is an ample stability safety margin during tasks that demand a high muscular effort, however, lighter tasks present a potential hazard of spine buckling, especially if some reduction in passive joint stiffness is present. Expand

TLDR
This study supports the clinical use of push-up progressions to facilitate activation of the serratus anterior and the upper trapezius during upper extremity rehabilitation. Expand

TLDR
Comparing the electromyographic activity of the trunk muscles during seven stabilization exercises using a gym ball found that push-up exercise resulted in the highest activity of all abdominal muscles, and an exercise of the lifting the gym ball up, holding it actively between both legs with both knees flexed in supine position results in the lowest muscle activity of back extensor muscles. Expand
Quantitative intramuscular myoelectric activity of lumbar portions of psoas and the abdominal wall during a wide variety of tasks.
TLDR
Consideration of deep muscle activity, provided in this report, is important for choosing the best abdominal exercise, together with activation profiles during lifting, during twisting, and during hip rotation. Expand
Relative Balance of Serratus Anterior and Upper Trapezius Muscle Activity during Push-Up Exercises
TLDR
Clinical selection of exercises for improving scapular control should consider both maximum serratus activation and upper trapezius/serratus anterior ratios and the push-up plus is an optimal exercise. Expand
Abdominal muscle response during curl-ups on both stable and labile surfaces.
TLDR
Performing curl-ups on labile surfaces changes both the level of muscle activity and the way that the muscles coactivate to stabilize the spine and the whole body, which suggests a much higher demand on the motor control system, which may be desirable for specific stages in a rehabilitation program.

TLDR
Results indicated that the frequency response of both the upper and lower erector spinae musculature can be modelled with a cut-off frequency between 2 and 2.5 Hz and that these values are not significantly modulated by changes in muscle length or tension. Expand
Cost-benefit of muscle cocontraction in protecting against spinal instability.
TLDR
Antagonistic cocontraction was found to be most beneficial at low trunk moments typically observed in upright postures, and empirically measured antagonistic coc ontraction was recruited less in high-moment conditions and more in low-moments. Expand
Trunk stiffness increases with steady-state effort.
TLDR
The measured increase in trunk stiffness probably results from increased muscle stiffness with increased muscle activation at higher steady-state efforts, which is believed to stiffen and stabilize the trunk. Expand
