REPORT Activity 2: Twitch Contractions and Summation PREDICTIONS Effect of Muscle Fiber Length on Contraction 1. As muscle fiber length increases: contraction force increases‚ becoming maximum at an optimal length‚ then decreasing at longer lengths. Effect of Stimulation Frequency on Contraction 2. As the frequency of stimulation increases‚ the force of contraction: increases. MATERIALS AND METHODS Measurement of Threshold Stimulus 1. Dependent Variable: contraction force. 2. Independent

Paula Radcliffe Skeletal The long term effects of Paula’s skeletal system is that her bones will get stronger‚ this is due to the bones density increasing‚ and calcium increasing in the bones. Another effect is that her ligaments would become more flexible. This is due to the elasticity increasing‚ therefore reducing any risk of injury from a pulled/ripped ligament. The amount of synovial fluid she produces would also go up. This would help her‚ because synovial lubricates the

The Fiscal Stimulus‚ Flawed but Valuable But I’m also an empirical economist who’s spent a career trying to estimate the effects of monetary and fiscal policy. So let me put on my empiricist’s hat and evaluate what we know about the legislation’s effects. After listening to Representative Paul Ryan in the vice-presidential debate‚ you might think that careful evaluation isn’t needed. In his view‚ we spent $800 billion on the stimulus‚ yet unemployment still rose to 10 percent — so obviously it

In December 2008 the government introduced a $10.4 billion stimulus package; the Economic Security Strategy‚ and in February 2009 the $42 billion National Building and Jobs plan was introduced (see Appendix A for details of the Stimulus). The aim of both stimulus packages was to stimulate the economy as

The muscle was consistently moistened by Ringer’s solution throughout the entire experiment. The Achilles tendon was removed at the heel of the frog. The tibiofibular bone was cut below the knee and the femur below the knee (Frog Skeletal Muscle Experiement). The baseline value of the force transducer was set to zero. This zeroing
