Question

Group Exercise Chapter 7 Wrist and Hand Joint After analyzing each exercise in the chart, break each into two primary movement phases, such as a lifting phase and a lowering phase. For each phase, determine the wrist and hand joint movements occurring, and the list the wrist and hand joint muscles primarily responsible for causing/controlling those movements. Beside each muscle in each movement, indicate the type of contraction as follows: I-isometric; C- concentric; E-eccentric. Exercise Initial movement (ifting) phase Secondary movement (lowering) phase Movement(s) Agonist(s)-(contraction type) Movements) Agonists)-(contraction type Push-up Bench press Ball squeeze risbee throw
