Principles of Strength Training Overload Strength, power, & endurance of muscle can only increase when a muscle performs workloads ______ ________________________________________ To improve, the system must be ______________and gradually challenged or placed under additional stress. 9. Principles of Strength Training Overload . . . Overload might be achieved by increasing the Resistance Repetitions or sets Rate (intensity) of work or exercise Duration of work or exercise Training load should be used so that the workload is difficult enough that the final set is difficult to complete. 10.Principles of Strength Training Progressive Resistance Exercise (PRE) __________________, but does so in a progressive, gradual manner avoiding overtraining and fatigue. Specificity (SAID – Specific Adaptations to Imposed Demands) Training must be______________________________. 11.Principles of Strength Training Specificity . . . Effects of the conditioning program are ________to the type of stress applied and to the particular ________of the body that is exercised. “If the body is placed under stress of varying intensities and durations, it attempts to overcome the stress by adapting specifically to the imposed demands” (Allman 1974). 12.Principles of Strength Training Specificity . . . Stress should not be so severe as to ___________ from being able to cope or adapt.

Allow the athlete to “______” during the competitive season. Helps to decrease the possibility of __________by varying exercise selection, intensity, volume, and load. 15. Periodization Phases _______________ (Preparatory) Phase High volume, low intensity workouts. Focus on proper technique and provide foundation. Power & strength workouts introduced during second half of this phase. ______________ (Competitive) Phase Focus on technique. High intensity technique exercises during brief workouts. Bring performance to “peak”. 16. Periodization ______________ (Transition) Phase Active rest, where the athlete should engage in recreational physical activity so that a psychological as well as physiological break can occur.

Strength Training Considerations Muscle Soreness Delayed onset muscle soreness DOMS can occur after strength training lasting 2-3 days, generally presenting on the day following activity.__________________. ____________is a by-product of muscle use and can cause the “burning” sensation felt during strength training. Seek medical attention if there is unusual pain, swelling, or if injury is suspected. 26. Testing Strength Manual muscle testing Resisting the active contraction of a muscle group and comparing with the opposite extremity or an expected level. Test throughout the functional range of motion. Standardized Grading: Normal = grade 5, 100% Good = grade 4, 75% Fair = grade 3, 50% Poor = grade 2, 25% Trace = grade 1, 10% No contractility = grade 0, 0% 27.

Testing Flexibility ____________Test Good for indicating low back & hamstring tightness. Sit with legs straight, placing both feet against a box, and reach the fingertips of both hands over a ruler attached to a box. Measure in inches, either plus or minus with minus scores indicating tightness. 37. Testing Flexibility ___________r Test Athlete stands with arms flexed at 90°, elbows fully extended. Externally rotate both arms as far as possible. “Loose” if they can rotate their palms beyond horizontal (if little finger is higher than thumb). _________Test Active dorsiflexion of the ankle measured with a goniometer. 15° is normal. 38. Testing Flexibility ____________Test Athlete lies supine and pulls one knee up to the chest with both arms while extending the opposite leg onto the floor. Should be able to extend the leg fully. Reverse for the opposite hip. All of these test determine tightness or looseness of muscles. Any athlete found to have a deficit should be placed on a specialized stretching program. 39.
