Beneficial to endurance athletets ( marathon runners, 10,000m runners and cyclists ) as they predominantly use aerobic energy system to create ATP
What does altitude training involve and what it aims to develop
training for a minimum of 30 days at an altitude of at least 1500m above sea level, although most choose to train at 2500M + above sea level
to develop aerobic energy system and is used to increase a performers VO2 max
What happens to pressure of oxygen during altitude training
At altitude, partial pressure of oxygen is lower, so haemoglobin isn't fully saturated, which lowers the oxygen carrying capacity of the blood
At first, athletes won't be able to train as hard as normal due to lower oxygen levels
After a period of time, the body responds to low pressure of O2 by producing more of the hormone EPO which stimulates the production of red blood cells
Red blood cells contain haemoglobin so body can carry more oxygen
Advantages of altitude training
Increase in the number of red blood cells.
Increased capacity to carry oxygen
Increased capillarisation
Increased concentration of haemoglobin and myoglobin
Increased lactate tolerance / delay OBLA
Develops aerobic energy system
Increased VO2 max
Benefits last for up to 6 to 8 weeks
Disadvantages of altitude training
altitude sickness
loss of fitness may occur as performer is unable to train at same intensity at altitude
benefits lost quickly when back at sea level
body only produce limited amount of EPO
psychological problems ( time away from home )
not suitable for sports using anaerobic energy systems
Describe HIIT training
involves periods of high intensity exercise followed by periods of rest or low intensity exercise
uses ATP-PC and AG systems during high intensity exercise
uses aerobic system during low intensity exercise or rest
total duration = 20 - 60 minutes / 6-8 cycles
work intensity = high intensity work at 80-95% of max heart rate
work duration = short exercise duration ( 5 seconds - 8 mins )
recovery = short period working at low or rest at 40-50% of max heart rate
Advantages of HIIT
develops both anaerobic and aerobic energy systems
good for games players as use of all 3 systems replicates the game
intensity / rest can be altered to meet specific demands of a sport/position
can improve range of components of fitness ( aerobic endurance, anaerobic power )
completed in shorter time compared to continuous training
develops performers ability to buffer lactic acids and reduce fatigue in a game
Disadvantages of HIIT training
not appropriate for all sports and positions ( weight training better for rugby players )
Increases risk of injury due to high intensity intervals and INC stress on joints
SAQ more effective for games players
High intensity can negatively impact skill and lead to a loss of technique
Rest intervals differ by positions and sports so can be difficult to accurately work out
Explain plyometrics
high intense explosive exercises ( hopping,bounding and depth jumps )
aims to develop power ( strength x speed ) & explosive strength
improves ATP-PC system due to rapid breakdown of ATP required
uses TYPE 2X fast twitch fibres
an eccentric contraction immediately followed by a concentric one
Explain the stretch-shortening cycle. - 3 phases in plyometric training
PRE-STRETCH - on landing, muscles perform eccentric contraction ( lengthens under tension )
AMORTISATION- is the time between eccentric and concentric contractions, during which elastic energy is stored. This time needs to be short so stored energy isn't lost
MUSCLE CONTRACTION - the concentric contraction phase uses the stored energy to increase force of contraction ( elastic recoil )
Role of proprioceptors in plyometrics
MUSCLE SPINDLES detect stretch of muscles on landing and sends impulses to the CNS ( a protective mechanism to avoid over stretching )
the STRETCH REFLEX occurs causing a rapid shortening of the muscle fibre ( concentric contraction)
this drives the performer up, and overtime will increase power of the jump
Advantages of plyometrics
increased size of fast twitch muscle fibres
increased speed of contraction
increased power of muscle contraction
increases strength of tendons reducing injury
no specific equipment needed so can easily be incorporated into session
could be combined with weight training to develop explosive power
Disadvantages of plyometrics
high risk of injury so must only be attempted after thorough warm up
correct technique must be used during training to avoid injury
could be argued that other components of fitness more important than power for games players ( like agility or aerobic endurance )
Describe SAQ training ( speed agility quickness )
aims to develop multidirectional movement, speed, dynamic balance, explosive strength
involves being coached correct techniques for movements
involves progression exercises to improve motor abilities to do skills faster more accurately
involves use of ladders, cones, poles, hurdles and parachutes
specifically develops ATP-PC as it focuses on short movement at high intensity ( 5-10 sec )
relies on rapid contraction of type two x fibres
drills focus on speed rather than endurance with rest intervals to allow PC replenishment
Advantages of SAQ training
improved reaction time
improves motor skills so develops coordination
improved spatial awareness allows players to notice teammates, opponents and the ball
increased muscular power and speed allows sprints to the ball
improved agility due to multi directional work, allows games players to change direction quickly ahead of opponents
Disadvantages of SAQ training
requires specialist equipment
can lose technique as skill carried out at fast speeds
not appropriate for long distance events
for unilateral explosive power events like high jump plyometrics more effective
