Q

outline the training guidelines for muscular strength/ endurance using FITT

A

T-no specific time (10-15 for beginners,15-20for endurance
sets-singles good for beginners, 2-4 for adults, more than 2 for advanced, rest= intervals of 2-3mins between sets)

Q

muscular fitness for adults?

A
  • 2-4 sets of 8-12 reps
  • 2-3min rest between sets
  • 60-70%1rm
21
Q

muscular fitness for older/deconditioned adult

A
  • 1set of 15
  • mid intensity
  • 40-50%1rm
22
Q

what are the long term effects of muscular strength/endurance?

A
  • stronger bines tendons ligaments
  • more joint mobility
  • increased muscle tone
  • increased hypertrophy
  • more neuromuscular connections/motor unit recruitment
  • improved posture
23
Q

flexibility=

A

range of motion around a joint/series of joints

24
Q

what determines flexibility?

A
  • shape of bones, cartiliage, length of connective tissue crossing over the joint
  • PERSON TO PERSON CHARACTERISTICS
25
Q

what is dynamic stretching?

A
  • moves limbs to lengthen muscles to the end of their ROM under control
  • no bouncing in movement
  • perform around 8-10 reps of each movement
26
Q

eg of dynamic stretches

A

leg curls raising heels to the buttocks to stretch the quads

27
Q

what is ballistic stretching ?

A
  • quick, repetitive bouncing/bobbing actions at the end of muscles’ normal ROM
  • momentum, speed, body weight activate stretch reflex in short term. Counterproductive as it shortens rather than lengthens muscles
  • in long term, this may increase firing threshold of stretch reflex to enable more ROM
  • not advised for beginner as can damage connective tissue
  • sometimes used in physiotherapy as a way of breaking down adhesions/ scar tissue
28
Q

eg of ballistic stretching

A

flexing from hip to reach toes and bouncing body weight down

29
Q

what is the FITT principle for dynamic stretches?

A

F-2-3days a week
I-to point of mild tension/discomfort
T-static stretches (10-30secs)
older adults may benefit from longer holds
2-4reps
PNF-static contraction 3-6secs followed by 10-30sec static stretch

30
Q

define immobility

A

significant lack of flexibility can dramatically affect posture/force production at a joint and impair performance/daily movements

31
Q

factors leading to immobility:

A
  • inactivity
  • certain sports limit flexibility (jogging, football-where muscles don’t go through full ROM= muscle tightness and adaptive shortening)
32
Q

define hypermobility

A

high degree of flexibility leads to a reduced joint stability and higher incidence of injury

33
Q

what is active static stretching? and eg

A

activity contracting 1 muscle group (agonist) to bring a stretch to the antagonist group
-eg=contracting tibias anterior will stretch out the gastrocnemius and actively stretching hamstrings lengthens quad muscles

34
Q

what is passive static stretching and eg?

A

where another body part/external force (wall/partner) used to facilitate the stretch, enabling both against and antagonist to relax
-eg=holding onto toes with hand or strap will relax tibalis anterior and will bring increased stretch of gastrocnemius

35
Q

what are the static stretching appllications?

A
  • used to lengthen muscles prior to exercise =

- maintain existing ROM and return muscles to normal length after finishing work

36
Q

what are maintenance stretches?

A
  • short stretches
  • used in warm up/cool down to maintain flexibility in muscles that are not particularly tight
  • taken to point of mild tension and held for 10-15 secs
37
Q

what are developmental stretches?

A
  • stretches held for longer 30-60secs
  • used in cool down in areas of tightness
  • not recommenced in warm ups
  • when tensions eases (stretch reflex relaxes), stretch taken further to improve ROM. process can be repeated moving further into stretch when muscle relaxes
38
Q

what is the FITT principle for improving motor fitness?

A

F-2-3days per week
I-n/a
T-20-30mins
T-balance,agility,power,coordination

39
Q

what are the considerations for FITT principle for improving motor fitness?

A
  • what components?
  • purpose of training?
  • ability of the individual?
40
Q

what are the factors affecting health/skill related fitness?

A
  • during formative years consideration needed on effects of exercise on developing bones/muscles/body systems
  • as people age muscles get weaker, bones loose density and joints get stiffer so have a lower training potential
  • negative effects of ageing on the body normally occurs around age of 50-65
41
Q

what age are most people when they are their most fittest?

A

in their 20s

42
Q

name some LT benefits of flexibility training:

A
  • improved ROM
  • lower muscle tightness/soreness
  • improved mobility
  • improved posture
43
Q

define body composistion

A

% of fat,bone,muscle in human body

44
Q

what are the % of body fat for athletes?

A

men=7-19%

women=10-25%

45
Q

what are the body fat % considered normal/healthy for adults ?

A

men=10-22%
women=20-32%
*of total body weight!!!

46
Q

what are the components of skill related fitness?

A
  • speed (how fast a movement can be performed in a shirt space of time)
  • power (ability to exert max muscular contraction instantly in an explosive burst of movement)
  • reaction time (ability to respond to stimuli quickly)
  • coordination (ability to smoothly move 2 or more body parts under control, accurately and efficiently)
  • balance (ability to control body position when stationary)
  • agility (ability to move direction/position of body quickly)
47
Q

outline some body composition traits for males/females

A
  • males tend to have less body fat and higher muscle mass
  • if women have lower body fat levels (significantly), then there is less oestrogen meaning cessation of menstral cycle leading to lower calcium levels and thus higher chance of osteoporosis
48
Q

what are the 3 body types?

A
  • ectomorph (naturally thin, narrow shoulders/hips, long levers, hard to gain weight)
  • mesomorph (naturally muscular, wipe shoulders, narrow hips, athletic)
  • endomorph (wide shoulders/hips, increased muscle fat,)
