In what way the energy cost per hop differ at the two frequencies and also how this is related to energy storage in tendons. Concept introduction: The locomotion is one of the most important characteristics of animals. It helps them to find mates, forage and to escape from enemies. The locomotion on land is mediated in animals by the structural adaptations that evolved over the time to overcome the force of friction and force of gravity that opposed the movement on land. The adaptations for movement include the presence of powerful leg muscles, strong skeletal support and storage of energy in the tendons while hopping (in some animals). Given data : The energy consumed when standing is 159 joules/sec. The energy consumed during hopping at different frequency is given as follows: Frequency (hops/sec) Energy used (joules/sec) 1.85 735 0.92 716

Summary Introduction

To determine: In what way the energy cost per hop differ at the two frequencies and also how this is related to energy storage in tendons.

Concept introduction: The locomotion is one of the most important characteristics of animals. It helps them to find mates, forage and to escape from enemies.

The locomotion on land is mediated in animals by the structural adaptations that evolved over the time to overcome the force of friction and force of gravity that opposed the movement on land. The adaptations for movement include the presence of powerful leg muscles, strong skeletal support and storage of energy in the tendons while hopping (in some animals).

Given data:

The energy consumed when standing is 159 joules/sec.

The energy consumed during hopping at different frequency is given as follows:

Frequency (hops/sec) Energy used (joules/sec)
1.85 735
0.92 716

Preoperative Diagnosis: Torn medial meniscus, left knee Postoperative Diagnosis: Combination horizontal cleavage tear/flap tear, posterior horn, medial meniscus, left knee. Operation: Arthroscopic subtotal medial meniscectomy, left knee Anesthetic: General endotracheal Description of Procedure: The patient was placed on the operating table in the supine position and general endotracheal anesthesia was administered. After an adequate level of anesthesia was achieved, the patient's left lower extremity was prepped with Betadine scrubbing solution, then draped in a sterile manner. Several sites were then infiltrated with 1% Xylocaine solution with Epinephrine to help control bleeding from stab wounds to be made at these sites. These stab wounds were made anterolaterally at the level of the superior pole of the patella for insertion of an irrigation catheter into the suprapatellar pouch area, anterolaterally at the level of the joint line for insertion of the scope and anteromedially at…
