311 Exam Two
Circuit training
performing exercises with minimal rest periods
• Rowing
power clean, clean pull, snatch pull, bent-over row, angled leg press, horizontal leg press, deadlift, stiff-leg deadlift, good morning
Power exercises and multiple-RM testing
power exercises do not lend themselves well to multiple-RM testing above 5 reps for repeated testing sets because technique can deteriorate rapidly.
• Freestyle swimming (including start & turns):
pull-up, lateral shoulder raise, forward step lunge, upright row, barbell pullover, single-leg squat
Core exercises
recruit one or more large muscle areas, involve two or more primary joints, receive priority because of their direct application to the sport
Assistance exercise
recruit smaller muscle areas, involve only one primary joint, considered less important to improving sport performance, used for injury prevention & rehabilitation (often isolate a specific muscle or muscle group)
Overload
refers to assigning a workout or training regimen of greater intensity than the athlete is accustomed to. To overload the athletes, increase the load assigned in the exercise, increase the number of sessions per week or per day, adding exercises or sets, emphasizing complex over simple exercises, increasing the length of the rest periods between sets and exercise, or any combination of these or other changes.
Somatic age
reflects the degree of growth in overall stature or smaller, subdimensions of the body (limb length).
Biomechanical advantage
short arms and a large chest cavity are a biomechanical advantage in upper body pressing exercises, whereas long legs and a long torso are a disadvantage in squatting movement.
Single-effort power events
shot put, high jump, weightlifting
Assistance exercises multiple-RM testing
should be at or above 8RM to minimize the isolative stress on the involved joint & connective tissue.
• Running, sprinting
snatch, clean, front squat, forward step lunge, step-up, leg (knee) extension, leg (knee) curl, toe raise (dorsiflexion)
Vertical jumping
snatch, power clean, push jerk, back squat, front squat, standing calf (heel) raise
Resistance training goal for preseason
sport and movement specific (strength, power, or muscular endurance, depending on the sport)
Youth resistance training program guidelines
static stretching after resistance training, begin with light loads, 1-3 sets, 6-15 reps, advanced multijoint exercises may also be included, 2-3 nonconsecutive training sessions per week, adult spotters should be nearby
Power exercises
structural exercises that are performed very quickly or explosively (maintaining a rigid torso and a neutral spine during the back squat)
Load
the amount of weight assigned to an exercise set (most critical aspect of a resistance training program)
SAID (specific adaptation to imposed demands):
the more similar the training activity is to the actual sport movement, the greater the likelihood that there will be a positive transfer to that sport
Agonist
the muscle or muscle group actively causing the movement
Repetition-volume for plyometric exercises
the number of foot or hand contacts
Training frequency
the number of training sessions completed in a given time period. The general guideline is to include at least 1 rest or recovery day, but not more than 3 between sessions that stress the same muscle groups.
Ossification
the process of laying down new bone material by cells called osteoblasts.
Exercise order
the sequence of resistance exercises performed during one training session (usually exercises are arranged so that an athlete's maximal force capabilities are available to complete a set with proper exercise technique). Power exercises (snatch, hang clean, power clean, push jerk) should be performed first, followed by other nonpower core exercises, then assistance exercises. If power exercises are not selected in exercise selection, then the recommended order of exercises is core and then assistance.
Antagonist
the sometimes passive muscle or muscle group located on the opposite side of the limb
Repetition-volume
the total number of repetitions performed during a workout session
Volume-load
the total number of sets multiplied by the number of repetitions per set, multiplied by the weight lifted per rep.

• Ball kicking
unilateral hip adduction & abduction, single-leg squat, forward step lunge, leg (knee) extension, leg raise
Postseason (active rest) training frequency
0-3 sessions per week
Inseason training frequency
1-3 sessions per week
1RM Testing Protocol :
1. Instruct the athlete to warm up with a light resistance that easily allows 5-10 reps. 2. 1 min rest 3. Estimate a warm-up load that will allow the athlete to complete 3-5 reps by adding: 10-20 lb or 5-10% for upper body exercises; 30-40 lb or 10-20% for lower body exercises. 4. 2 min rest 5. Estimate a conservative, near-max load that will allow the athlete to complete 2-3 reps by adding: 10-20 lb or 5-10% for upper body exercises; 30-40 lb or 10-20% for lower body exercises. 6. 2-4 min rest 7. Load increase: 10-20 lb or 5-10% for upper body exercises; 30-40 lb or 10-20% for lower body exercises. 8. Instruct the athlete to attempt a 1RM 9. If successful, 2-4 min rest and go back to step 7 10. If failed, 2-4 min rest, then decrease the load by subtracting: 5-10 lb or 2.5-5% for the upper body exercises and 15-20 lb or 5-10% for the lower body exercises.

Proper grip width & hand placement: • Fist-to-shoulder measurement: measuring the distance from the edge of the clenched fist of one hand to the opposite shoulder when the arm is straight out at the side. • Elbow-to-elbow: arms straight out to the side. Starting position: feet hip-to-shoulder width apart with the toes pointed slightly outward. Hand grip: closed, pronated. First pull: lift off to just above the knees. Transition (scoop): knees and thighs move forward and under the bar. Second pull (Power Phase): upward movement to where the lower body joints are fully extended. Catch: bar moves to an overhead position, arms & body are fully extended. Major muscles involved: gluteus maximus, semimembranousus, semitendinousus, biceps femoris, vastus lateralis, vastus intermedius, vastus medialis, recuts femoris, soleus, gastrocnemius, deltoid, trapezius. Common technique errors: the bar too far away from the body during the second pull (power phase), fast forward and upward jumping motion.
Hang Clean
Position the bar on the thighs just above the knees. Starting position: feet hip-to-shoulder width apart with the toes pointed slightly outward. Catch: bar is caught on the anterior deltoids and clavicles. Major muscles involved: gluteus maximus, semimembranousus, semitendinousus, biceps femoris, vastus lateralis, vastus intermedius, vastus medialis, recuts femoris, soleus, gastrocnemius, deltoid, trapezius.

Push Press & Push Jerk
Pushing the bar over the head quickly and forcefully. Push press: hip and knee thrust drives the bar ½ to 1/3 the distance overhead with hips and knees extended. Push jerk: hip and knee thrust more forceful and bar thrown or jerked upward. Starting position: bar in front of the shoulders, feet hip-to-shoulder width distance. Dip: not to exceed a quarter-squat, the catch position of the power clean or 10% of the athlete's height. Drive: reverse the movement forcefully and quickly extending the hips, knees and elbows to move the bar overhead. Catch (push press): similar to second half of the shoulder press, deltoids and triceps need to press the bar overhead. Catch (push jerk): bar caught overhead, elbows extended, knees flexed. Major muscles involved: gluteus maximus, semimembranousus, semitendinousus, biceps femoris, vastus lateralis, vastus intermedius, vastus medialis, recuts femoris, soleus, gastrocnemius, deltoid, trapezius. Common technique errors: exceeding the depth of the dip, a spotter is present.

Recommended frequency is 2 times per week to start with and progress to more frequent resistance training sessions. Warm up for 5-10 minutes before each exercise session, static stretching before or after or both before and after each resistance training session, avoid Valsava maneuver, allow 48-72 hours of recovery between exercise sessions.

Preactivation & cocontraction
muscle activity before (preactivation) and immediately following (cocontraction) contact with the ground is an important mediator of breaking and dynamic stabilization in both young and old individuals. Increased preactivation helps increase stiffness of the limb using fast stretch reflex to better prepare the limb for ground contact. Cocontraction is a motor control strategy that dynamically stabilizes the joint. Research shows that seniors (65 years of age and older) rely on increased levels of muscle cocontraction as a compensatory mechanisms to offset their increased balance difficulties and to minimize postural sway. Recommended exercises specifically designed to offset these natural reductions in preactivation are: low-intensity plyos, balance & dynamic stabilization exercises, and proprioception training to develop the ability to react more efficiently with the ground.
