Effects of Angle Variations in Suspension Push-up Exercise

Abstract

Gulmez, I. Effects of angle variations in suspension push-up exercise. J Strength Cond Res 31(4): 1017-1023, 2017-This study aimed to determine and compare the amount of loads on the TRX Suspension Trainer (TRX) straps and ground reaction forces at 4 different angles during TRX push-ups. Twenty-eight male (mean age, 24.1 ± 2.9 years; height, 179.4 ± 8.0 m; weight, 78.8 ± 9.8 kg) physical education and sports university students participated in this study. The subjects were tested at TRX angles (0, 15, 30, 45°) during the TRX push-ups. Force data were recorded by a force platform and load cells integrated into the TRX straps. The results show that as the TRX angle was reduced, the load applied to the TRX straps increased and simultaneously the load measured by the force platform decreased. This was true for both the elbow joint changing from flexion to extension and vice versa. When the TRX angle was set at 0° and subjects' elbows were at extension during TRX push-up, 50.4% of the subjects' body weight, and when the elbows were at flexion, 75.3% of the body weight was registered by the sensors on the TRX straps. The results of this study can be used in the calculation of the training load and volume (resistance training programming) during TRX push-up exercises at varying angles.

Short-Term Effects of Suspension Training on Strength and Power Performances

“…In particular, males showed significant increases in MVC (dominant limb: +7.7%; non-dominant limb: +6.1%), whereas no effects emerged in females. During ST sessions, the evaluation of the load distribution during each exercise could be affected by several biomechanical aspects, such as the body inclination, the length of ST device, the feet position, and the combination of these factors [3,7,15]. Therefore, it is possible that participants performed each exercise in the most comfortable position, thus leading to exercise-related arousal rather than fatigue in strength parameters.…”

“…Body weight resistance training is an inexpensive way to exercise effectively [1], with suspension training (ST) promoting multi-planar and multi-joint bodyweight exercises using two independently moving handles suspended by two straps with a fixed anchor position above the exerciser [2][3][4][5]. The load imposed by ST exercises is determined by three fundamental principles: vector-resistance (the inclination of the exerciser's body relative to the ground determines the intensity of the exercise), stability (the size and positioning of the base of support relative to the centre of gravity determines the stability of an exercise), and pendulum (the positioning of the centre of gravity relative to the anchor point determines the intensity of the exercise) [4,6,7].…”

“…Considering the popularity of ST, several studies were performed in the last 5 years to investigate the cardiovascular [8,9], neuromuscular [10][11][12][13][14] and biomechanical [3,7,15] characteristics of this activity. The unstable nature of the base of support characterizing ST has been reported to stress the neuromuscular system with greater muscular demands than traditional resistance exercises performed on stable surfaces [13,14,[16][17][18] with subsequent increases in strength, attributable to changes in muscle cross-sectional area and neuromuscular coordination [13,19].…”

Research on the education reform of TRX suspension training method applied in physical fitness course in Police Colleges

“…The principle of TRX suspension training is the body of some or all of the above, suspended from the fixed point of the rope or sling, or removed by adjusting the effect of special exercise treatment techniques of gravity and friction action factors, including technical suspension neck, upper and lower limbs and trunk [3]. TRX suspension training aims at restoring proprioceptive control, motor control, increased core stability, muscle strength, endurance, and cardiovascular function to improve the overall functioning of the motor system.…”

Progressive Overload Thera-Band Direnç Antrenmanlarının Esneklik Ve Yüzme Performansına Etkisi

“…When resistance training exercises are performed with clearly labeled masses such as dumbbells, weight plates and machines, the training volume and intensity can be easily calculated as a percentage of the maximum loads. However, it can be said that TRX push-up training results are a viable method for calculating the training load and volume in programming of resistance training (Gülmez, 2016;1017). Elastic bands are thought to be safe, effective and alternative resistance training methods in the training programs of athletes with specific physical and physiological needs, which are safe in terms of health and carry no risk (Colado, Garcia-Masso, Triplett, Flandez, Borreani & Tella, 2012: 3018;Agopyan, Ozbar & Özdemir, 2018: 73).…”
