The electromyographical-threshold (EMGT) has been previously validated as a means to predict the work rate at which lactate-threshold (LT) occurs. The reliability of these measures has yet to be examined after a bout of exercise. The purpose was to determine the agreement between EMG and LT after a 30-minute bout of steady-state aerobic exercise. P...
Snarr, RL, Tolusso, DV, Hallmark, AV, and Esco, MR. Validity of wearable electromyographical compression shorts to predict lactate threshold during incremental exercise in healthy participants. J Strength Cond Res XX(X): 000-000, 2018-Determination of lactate threshold (LT) is an important variable in improving cardiovascular endurance and performa...
The relationship between the lactate and electromyographical (EMG) thresholds have previously been established via graded exercising testing during cycling. Currently, no published literature exists comparing the most appropriate and efficient filtering methods of EMG analyses to estimate the workload at which lactate threshold (LT) occurs. PURPOSE...
The purpose of this investigation was to compare the electromyographical (EMG) activity of the latissimus dorsi (LD), posterior deltoid (PD), middle trapezius (MT), and biceps brachii (BB) while performing two pull-up variations. Resistance-trained men and women (n = 13, age = 24.26 ± 6.24) volunteered to participate in this study. All participants...
Strengthening muscles of the back may have various implications for improving functions of daily living, aiding in the transfer of power in throwing, and assist in injury prevention of the shoulder complex. While several versions of the pull-up exist, there is currently no literature comparing their differences. The purpose of this investigation wa...
Proper determination of lactate threshold (LT) is an important variable in improving cardiovascular endurance and performance. Unfortunately, monitoring LT during exercise is a costly, invasive blood analysis, which requires either capillary blood samples or an indwelling venous catheter. However, electromyography (EMG) is a potential new method of...
Monitoring physiological markers during aerobic conditioning and performance is a key determinant of success. Several laboratory methods have previously been used to determine appropriate training levels such as lactate threshold, ventilatory threshold, and heart rate deflection point. Heart rate deflection point and lactate threshold are typically...
Purpose:
The purpose of this investigation was to compare the electromyographical differences of the rectus abdominis (RA), external oblique (EO), erector spinae (LSES), and rectus femoris (RF) during pike variations performed on various surfaces.
Methods:
Twenty men and women volunteered for this study. All subjects performed five variations of...
The purpose of this study was to compare the electromyographic (EMG) activity of global trunk musculature during common training exercises. Twenty apparently healthy men (age 25.9 ± 5.6 years; height 175.22 ± 8.46 cm; weight 81.28 ± 6.86 kg) and women (age 22.8 ± 1.81 years; height 166.06 ± 8.47 cm; weight 63.03 ± 10.38 kg) volunteered to participa...
As instability devices and unstable training rise in popularity in athletic conditioning programs, fitness centers, and rehabilitation clinics determining the effectiveness and safety of these devices is important. Instability devices are primarily used with the intent of increasing the intensity of traditional exercises by providing further muscul...
The pull-up is a closed kinetic chain exercise that is aimed to increase muscular strength and endurance in the upper extremities and torso. Therefore, this exercise may be beneficial for improving functions of daily living, aiding in the transfer of power in throwing movements, and preventing injuries of the shoulder joint complex. There is limite...
