what has been shown to be a better indicator of aerobic endurance performance than both lactate threshold & V02 max?

maximal lactate steady state

what is the best indicator of aerobic endurance performance out of the 3: lactate threshold V02 max maximal lactate steady state

maximal lactate steady state

maximal aerobic capacity (V02 max)

maximum rate of oxygen consumption measured during incremental exercise

exercise economy

measure of energy cost of activity at a given exercise velocity

metabolic rate is closely related to what?

mechanical power production

if V02 max testing is not available, what can you use to regulate exercise intensity?

-HR (most frequently used) -ratings of perceived exertion -metabolic equivalents -exercise velocity

what is the work to rest ratio for interval training?

1:1 there should be as much work as there is rest. i.e. if there is 3 min of work, there should be 3 min of rest

what are the benefits to cross training?

-adaptations of respiratory, cardiovascular, & musculoskeletal systems -maintain some level of conditioning in single event athletes

metabolic equivalent (MET)

-also may be used to prescribe exercise intensity -one MET = 3.5ml x kg x min of 02 consumption & is considered the amount of 02 need by the body at rest

Farlek training:

-combo of several of the other types of training (LSD, pace/tempo, HIIT) but is generally associated with running -easy running combo with sprints -challenges all systems of the body & may help reduce the boredom & monotony associated with daily training -benefits: enhance V02 max, increase lactate threshold, improve running economy & fuel utilization -intensity: varies between LSD & pace/tempo training intensities -duration: about 20-60min -frequency: 1x/week

pace/tempo training

-employs an intensity at or slightly higher than race competition intensity -perform 1-2days/week -duration: 20-30min

what are the physiological benefits derived from LSD training? all of those changes will in turn, be able to do what?

-enhanced cardiovascular & thermoregulatory function -improved mitochondrial energy production & oxidative capacity of skeletal muscle -increased utilization of fat as fuel these changes will help clear out lactate faster, therefore meaning that lactate threshold will be improved. there also might be a shift to type 1 muscle fibers if this training method is used chronically

frequency of training sessions depend on what (4)?

high intensity interval training (HIIT)

-form of training that uses repeated high intensity exercise bouts interspersed with brief recovery periods -intensity: several minutes spent above 90% V02 max -short & long HIIT intervals can be used to elicit different responses -benefits: improves running speed & economy; helps in final "push" or "stretch" of race/competition -duration: 30-90sec with work ratio of 1:5 -frequency: 1x/week

what are the factors that play a significant role in successful aerobic endurance performance?

-maximal aerobic capacity (V02 max) -lactate threshold -exercise economy -high efficiency in using fat as a fuel source -high percentage of type 1 muscle fibers

cross training

-mode of training that can be used to maintain general conditioning in athletes during periods of reduced training due to injury or during recovery from a training cycle -may reduce likelihood of overuse injuries bc it distributes the physical stress of training to muscle groups different from those used during training

what are the most accurate methods for regulating exercise intensity?

-monitor oxygen consumption during exercise to determine V02 max -periodically measure the blood lactate concentration to determine the relationship to the lactate threshold

describe the training program for an athlete in season:
