Answer 1

prolonged reduction in absolute strength and endurance of a muscle due to excessive activity

Question 2

What are some symptoms of overwork weakness

Answer 2

delayed onset muscle soreness

decreased max force

Question 3

What did Dal Bello Haas find about strength exercises in MND

Answer 3

significant improvement in activity
7% improvement in function
no evidence of adverse effect

Question 4

What conclusions did the evidence for respiratory muscle training in MND come up with

Answer 4

used inspiratory tool that provided resistance on inspiration vs control who usesd same device, no resistance - both increased max inspiratory pressure

What are strategies to provide strengthening exercise without producing overwork weakness

Answer 5

begin with mild/moderate intensity
monitor fatigue
restrict high intensity training of each muscle group to 3x per week
progress by changing one training parameter at a time
