Chapter 4: Training and Conditioning Techniques What is one of the primary causes of sports injury? Lack of physical fitness What is periodization? An approach to conditioning that brings about peak performance while reducing injuries and over-training in the athlete through a training and conditioning program that is followed through-out the various seasons What are the three seasons of sports conditioning? Off-season Pre-season In-season How does periodization organize a training and conditioning program? Cycles The complete training period (which could be a year in the case of seasonal sports or perhaps four years for an Olympic athlete) is referred to as what? Macrocycle The series within a macrocycle are referred to as what and how long do they last? Mesocycle, which may last for several weeks or even months How are mesocycles divided? Transition period Preparatory period Competition period When does the transition period begin? After the last competition and comprises the early part of the off-season What type of training activity is involved with the transition period? Unstructured and recreational What is the idea behind the transition period? To allow the athlete to escape both physically and psychologically from the rigor of a highly organized training regimen When does the preparatory period occur? During the off-season when there are no upcoming competitions What are the three phases of the preparatory period? Hypertrophy/endurance phase, strength phase, power phase When does the hypertrophy/endurance phase occur? In the early part of the off season in the early part of the preparatory period What type of training activity is involved with the hypertrophy/endurance phase? Low intensity with a high volume of repetitions, using activities that may or may not be directly related to a specific sport What is the goal of the hypertrophy/endurance phase? To develop a base of endurance on which a more intense training can occur How long does the hypertrophy/endurance phase last? From several weeks to two months When does the strength phase occur? During the off season in the middle of the preparatory period What type of training activity is involved with the strength phase? Intensity and volume progress to moderate levels, where weighttraining activities become more specific to the sport or event When does the power phase occur? Pre-season, end of preparatory period What type of training activity is involved with the power phase? High intensity at or near the level of competition. The volume of training is decreased so that full recovery is allowed between sessions How long does the competition period last? In certain cases the competition period may last for only a week or less. With seasonal sports, however, the competition period may last for several months. What type of training activity is involved with competition period? High intensity training at a low volume. As the training volume decreases, an increased amount of time is spent on skill training and strategy sessions. During the competition period, what may be necessary to establish? Microcycles What is a microcycle? Periods which last from one to seven days What type of training activity is involved with a microcycle? Training should be intense early in the week and should progress to moderate and finally light the day before the competition. What is the goal of the microcycle? To make sure that the athlete will be at peak levels of fitness and performance on days of competition What is the concept cross training? An approach for a specific sport that involves substitution of alternative activities that have some carryover value to that sport (swimmer engages in jogging, running or aerobics to maintain levels of cardiorespiratiory conditioning) When should cross training not be used and why? Pre-season because it is not sportsspecific What are the ten principles that should be applied in all programs of training and conditioning to minimize the likelihood of injury? Warm-up/cool-down Motivation Overload (SAID principle, specific adaptation to imposed demands) Consistency Progression Intensity Individuality Minimize stress Safety What is the function and purpose of the warm-up? To prepare the body physiologically for some upcoming physical work. To gradually stimulate the cardiorespiratory system to a moderate degree, thus producing an increase blood flow to working skeletal muscles and resulting in an increase in muscle temperature. What does the cool down enable the body to do? Cool and return to a resting state How long should the cool down last? Five to ten minutes What does a proper cool down help rapidly decrease? Blood and muscle lactic acid levels What is flexibility? The ability to move a joint or a series of joints smoothly and easily throughout a full range of motion What does a lack of flexibility result in? Uncoordinated or awkward movements and predisposes the athlete to muscle strain What are the factors that limit flexibility? Bony structure Fat Skin Muscles and their tendons Connective tissue What is active range of motion (dynamic flexibility)? The degree to which a joint can be moved by a muscle contraction, usually through the mid-range of movement What is passive range of motion (static flexibility)? The degree to which a joint may be passively moved to the endpoints in the range of motion. No muscle contraction is involved to move a joint through a passive range. Why is passive range of motion important for injury prevention? In many sports situations, the muscle is forced to stretch beyond its normal limits. If the muscle does not have enough elasticity to compensate for this additional stretch, the musculoskeletal unit will likely be injured What is ballistic stretching? Bouncing movement in which repetitive contraction of the agonist muscle are used to produce quick stretches of the antagonist muscle. Although ballistic stretching is effective in improving range of motion, why has it been criticized? Because the increased range of motion is achieved through a series of jerks or pulls on the resistant muscle tissue. The forces generated by the jerks are greater than the tissues extensibility which may cause muscle injury. What is static stretching? Passively stretching an antagonist muscle by placing it in a maximal stretch and holding it there. What are the recommendations for the optimal time for holding the stretched position? It ranges from as short as three seconds to as long as sixty seconds What has recent data indicate as the optimal time for holding a stretch? Thirty seconds How many times should the static stretch be repeated? Three or four times What is PNF? Stretching techniques that involve combinations of alternating contractions and stretches What does PNF stand for? Proprioceptive Neuromuscular Facilitation If weight training is done properly through a full range of motion, what will not be impaired? Flexibility What is muscular strength? The ability of a muscle to generate force against some resistance (the maximum force that can be applied by a muscle during a single maximum contraction) What is muscular endurance? The ability to perform repetitive muscular contractions against some resistance for an extended period of time (the ability to perform repetitive muscular contractions against some resistance) What are the three types of contractions skeletal muscle is capable of? Isometric Concentric Eccentric What is an isometric contraction? Contracts the muscle statically without changing its length What is a concentric (positive) contraction? The muscle shortens while contracting against resistance What is an eccentric (negative) contraction? The muscle lengthens while contracting against resistance What is hypertrophy? Enlargement of a muscle caused by an increase in the size of its cells in response to training What is atrophy? Decrease of a muscle caused by the decrease of the size of its cells because of inactivity
