Comparing the use of free weight or machine resistance for the power clean performed from the mid-thigh position, Jones et al. (2008) found that 1RM and average power were greater when using free weights but velocity (average and peak) was greater when using the machine loading.
Comparing squat variations, Russell and Phillips (1989) reported that peak hip extensor moments were greater during the back squat than in the front squat, even when each variation was performed to a standardized depth and with the same relative load.
Wretenberg et al. (1996) similarly observed that peak hip extensor moment was greater when heavier loads were used, although this was likely also a function of differences between powerlifting and Olympic weightlifting styles of squat.
Also comparing the effect of load but using near - maximal and maximal loads, Harbili & Alptekin (2014) found that when comparing the maximal load to the near - maximal load, there was a reduction in both peak barbell vertical displacement (1.25 vs 1.27 m) and peak vertical barbell velocity (1.72 vs. 1.82 m / s).
However, increases in muscle fascicle length are also likely dependent on the mechanical load incurred by the prime mover, as knee flexion (hamstring only) exercise seems to lead to greater adaptations in the hamstrings than hip extension (hamstring, gluteus maximus, and adductor magnus) exercise, even when muscle length at peak contraction is shorter (Bourne et al. 2016).
For example, when comparing constant load (free weight) and constant resistance (pneumatic machine) bench presses, the constant resistance bench presses involve higher peak velocities, because they allow greater acceleration at the start of the movement (Frost et al. 2008).
And assuming that maximal bar speed is attempted, this produces a different peak velocity for the same force when using each external load type.
In contrast, they found no difference in peak bar velocity at all loads except 75 % of 1RM when comparing the bench press throw immediately preceded by a fast eccentric muscle action and the concentric - only muscle action condition.
Comparing the effects of different training variables, Swinton et al. (2011a) found that there was no difference in peak knee joint angles when using relative loads ranging between 10 — 80 % of 1RM with the straight bar and hexagonal bar deadlifts.
Are there peak periods, such as the start of the day or immediately after breaks and lesson changeovers when the system will be under particularly heavy loads?
Having it operate at it's peak RPM & load all the time with no transmissions saves fuel, as well as recapturing much of the energy when braking; the new Jake Brake would be regenerative braking.
When energy use approaches peak loads (where the less efficient power plants come online), they start taking action.
The ability to program the charging or discharging of the battery at off peak times making use of late at night energy when there is access wind power not being utilized or shifting day tome loads to night time battery storage.
These technologies minimize a consumer's load during peak periods or shift a consumer's load when renewables are generating electricity.
Modeling has also shown that it's relatively inexpensive to increase the reliability of the total wind output to a level equivalent to a coal - fired power station by adding a few low - cost peak - load gas turbines that are opearated infrequently, to fill in the gaps when the wind farm production is low (Diesendorf 2010).
High atmospheric moisture loading will continue to pump up peak storm potentials when storms do form.
The rapid growth came as lawmakers wrestled with how to deal with the solar incentive policy, which required revision when rooftop solar capacity reached 3 % of peak load.
«An aggregated fleet of vehicles or chargers can act as a [demand response] resource, shifting load in response to price signals or operational needs; for example, vehicle charging could be shifted to the middle of the day to absorb high levels of solar generation and shifted away from evening hours when solar generation disappears and system net load peaks
«This form of renewable energy is a long way from being able to be a base - load supplier of power when it is needed most at peak demand.»
The duck curve shows a major drop in electric load in midday when solar hits its peak, swamping the grid at a period of low demand and potentially pushing net load below the point where older baseload plants can ramp down to compensate.
