energy systems
fuel - in body + cp stores
efficiency - very limited
duration - 2s + 8-10
fatigue - depletion of co
by products - heat
rate of recovery - 2-5 min
fuel - carbs
efficiency - limited
duration - 30s
fatigue - build up faster than quantities removed
by products - pyruvic acid
rate of recovery - 30-60min
fuel - carbs, fat and protein
efficiency - metabolism of fuel
duration - 12hr to 1 hour of work
fatigue - switch from glycogen to fat
by-products - co2 and water
rate of recovery - depends on duration
types of training
continuous (20+ mins, 3-4 times a week)
fartlek (anaerobic and aerobic, 2-3times a week for 20-30 min)
interval (alternating)
circuit
speed (all year)
agility (rapidly change direction)
acceleration (1-2 times a week)
power (degree of strength)
factors (age, gender, temperature)
benefits (reciprocal inhibition, less tension)
static (30-120s)
dynamic (active stretching)
ballistic (repeated jerking)
pnf (static, isometric contraction, relax, stretch)
machines
free weights
resistance bands
stability balls
medicine balls
principles of training
most common
improve by 10%
prevents plataeu in performance
targeted towards goals of the athlete
effects of training if it ceases
greater gains = greater loses can be made
prevents boredom
aerobic - 60%
anaerobic - 85%
enhance performance, range of motion and prevent injury
warm up (10-15 min)
cool down (remove blood lactate)
physiological adaptations
bpm
declines as training
blood ejected in one contraction
increases with training
hr x sv
stays same
air exhaled in one breath
doesn’t change
protein that assists with oxygen transportation
aerobic training increases it
increased muscle cross-sectional size
length doesn’t change but size will
slow (endurance)
fast (short)
