The effects of training the biceps brachii muscle to failure
… A series of experiments measuring the size, maximum force, and relationship between force and electromyographic signal of the biceps muscles was used to test the effectiveness of the failure routine. The month long training program was found to produce significant size and strength gains in …

Force generating capacity of human muscle
The proportion of maximum force (% PF max) utilised during cycling exercise was determined within a group of trained and untrained subjects. Maximum forces were determined isokinetically and submaximum forces were measured during continuous progressive exercise tests.

Objective gait analysis in humboldt penguins (spheniscus humboldti) and domestic ducks (cairina moschata domestica) using a pressure sensitive walkway
… up to 24 hours post injection identified that maximum force and impulse were significantly lower for the affected limb at the 3- and 4-hour time points. This model allowed for repeatable objective assessment of lameness in domestic ducks with maximum force and impulse serving as the most …

A Tale of Two Studies: A Biomechanical Comparison of Extrapelvic and Intrapelvic Fixation for Acetabular Fractures among the Elderly and a Comparison of Dosage Accuracy and Precision for Traditional and Incremental Syringes
… significance (p < 0.05) reached for yield force, maximum force, and plastic energy. From these results it might be concluded that the intrapelvic plate does not begin contributing significantly towards the strength of the acetabulum until higher loads are reached. However, reoccurring …

The Impact of Lower Limb Dominance on Side-to-Side Symmetry in Daily Living and Sports-related Tasks
… USA), plantar loading data such as peak impact force and loading rate was calculated. Participants completed one sit-to-stand trial and three 10-meter walking trials, as these serve as prime examples of daily activities. The secondary purpose of this study was to assess the impact of lower limb …

A multi finger electromagnetic actuator apparatus for biomechanical studies on the hand
… were designed and constructed and a position and force feedback control system was implemented for each. The maximum continuous force output for each actuator ranged from 12-16 N, which is about 15%-30% of the maximum force that can be exerted by an individual finger. The bandwidth of the …

In Vivo Forces of Male Urethral Catheterization
… to quantify typical urethral catheter insertion forces of male anatomy in vivo. This provided a quantitative range of forces that may be used to objectively evaluate trainees or educational simulators. A custom-made Handheld Catheter Insertion Force Assessment tool (+/- 0.29N accuracy) was used …

The Role of Calcium in the Mechanism of Muscle Fatigue in Intact, Single Muscle Fibres of Mice at Physiological Temperature
… submaximal stimulation until 40% of initial force. A force-[Ca2+]m relationship was determined prior to fatigue and during a 35 min recovery period. During fatigue, [Ca2+]m at 50% of maximum force (Ca50) increased significantly, demonstrating a decrease in Ca2+ sensitivity. Early in the …

The use of antagonist muscle as a "catch" in explosive movement/
… It was shown that for loads below 30% of the maximum force of the muscle, using an antagonist muscle as a catch could produce beneficial power amplifications. These amplifications increase as the load and muscle release rates decrease.

The development and characterization of soft robotic contractile actuators
… would be required to generate physiological force for blood ejection. However, McKibben PAMs with thermoplastic polyurethane (TPU) bladders were too bulky and prevented the embedding of additional actuators. Therefore, multiple alternate PAM designs which occupy minimal unpressurized volume …

Maximum Isometric Force Production Characteristics in Five Muscle Groups in Physically Active Young, Middle-Aged, and Older Men
… function was assessed in terms of the static force production capacity of the finger flexors, thumb abductors, forearm extensors, plantar flexors and dorsiflexors, reflected by variables representing parameters of force, time, rate of force production, and cumulative force over time (impulse). …

Die Wirkung moderater Hypothermie auf Kontraktilität und calciuminduzierte Inotropie von humanem atrialen Myokard
… ventricular myocardium. We measured contraction force, time relationship and its reaction to different positive inotropic agents such as calcium, isoproterenol and the phosphodiesterase inhibitor milrinone. Temperatures ranged between 37° C and 31°C. Human atrial muscle stripes were obtained from …

Effects of Prolonged Running on Ground Reaction Force Patterns Wearing Shoes of Different Midsole Durometers (Fatigue)
Selected force events and the relative timing of their occurrence, were chosen for evaluation from the GRF curves obtained from 15 subjects, 18 to 49 years, running "as hard as possible." GRFs were measured on a force platform at the start, middle, and end of one hour of running. Testing took place …

Experimental study of the development of plastic solitary waves in one-dimensional granular media
… wave speed of this pulse was seen to depend on maximum force, as in the elastic as, although it was measured to be less than the elastic wave speed. In addition, the plastic velocity varied with the 1/9th power instead of the 1/6th power for the elastic speed. For the case of brass, the plastic …
