00:00:20,630 --> 00:00:18,800
hi everyone this is uh mike hopkins

3
00:00:22,470 --> 00:00:20,640
astronaut with nasa coming to you from

4
00:00:24,550 --> 00:00:22,480
the countermeasures training room here

5
00:00:26,230 --> 00:00:24,560
at nasa jsc

6
00:00:27,990 --> 00:00:26,240
and today or this morning i want to talk

7
00:00:30,710 --> 00:00:28,000
to you a little bit about the treadmill

8
00:00:32,790 --> 00:00:30,720
that we use when we're up on orbit now

9
00:00:34,709 --> 00:00:32,800
you may look at it it seems very similar

10
00:00:36,790 --> 00:00:34,719
to the treadmills you use at home but

11
00:00:38,389 --> 00:00:36,800
there are a lot of differences with this

12
00:00:40,950 --> 00:00:38,399
treadmill particularly in how we're able

13
00:00:43,110 --> 00:00:40,960
to use it but we also have an isolation

14
00:00:45,030 --> 00:00:43,120
vibration isolation system with this

15
00:00:47,670 --> 00:00:45,040
treadmill and what that does is as we're

16
00:00:49,750 --> 00:00:47,680
running it keeps those vibrations uh as

17
00:00:51,510 --> 00:00:49,760
we pound on the treadmill from being

18
00:00:52,709 --> 00:00:51,520
transferred to the space station itself

19
00:00:53,990 --> 00:00:52,719
and that's actually pretty important

20
00:00:55,750 --> 00:00:54,000
because here on earth when you run

21
00:00:56,549 --> 00:00:55,760
you've got a great damping system called

22
00:00:58,150 --> 00:00:56,559
earth

23
00:01:00,709 --> 00:00:58,160
but we don't have that up in space and

24
00:01:02,150 --> 00:01:00,719
so we need to make sure that we're not

25
00:01:03,349 --> 00:01:02,160
impacting the station while we're

26
00:01:05,030 --> 00:01:03,359
working out

27
00:01:07,590 --> 00:01:05,040
now one of the other major differences

28
00:01:08,630 --> 00:01:07,600
with with the treadmill is that we have

29
00:01:10,550 --> 00:01:08,640
to

30
00:01:12,390 --> 00:01:10,560
use a harness much like a backpacking

31
00:01:14,789 --> 00:01:12,400
harness that you have

32
00:01:17,429 --> 00:01:14,799
when you when you go hiking and so what

33
00:01:18,950 --> 00:01:17,439
we use this for is to help hold us down

34
00:01:21,109 --> 00:01:18,960
on the treadmill because remember when

35
00:01:23,190 --> 00:01:21,119
we're in space we're floating around and

36
00:01:25,350 --> 00:01:23,200
so it's hard to stay down on the track

37
00:01:27,510 --> 00:01:25,360
so we put this

38
00:01:29,670 --> 00:01:27,520
little harness on

39
00:01:31,030 --> 00:01:29,680
and then we have to strap ourselves

40
00:01:33,030 --> 00:01:31,040
to the treadmill

41
00:01:35,190 --> 00:01:33,040
so once we get strapped in with the

42
00:01:37,510 --> 00:01:35,200
harness and the bungees we have a

43
00:01:39,270 --> 00:01:37,520
computer that we actually use that has

44
00:01:40,950 --> 00:01:39,280
different workouts on it and the neat

45
00:01:42,550 --> 00:01:40,960
thing about this as well is

46
00:01:43,990 --> 00:01:42,560
not only does it have a workout on it so

47
00:01:45,990 --> 00:01:44,000
we can change the speed and whether

48
00:01:48,149 --> 00:01:46,000
we're doing interval workouts or longer

49
00:01:49,749 --> 00:01:48,159
distance but while we're working out

50
00:01:51,429 --> 00:01:49,759
it'll actually record our heart rate

51
00:01:53,109 --> 00:01:51,439
it'll record the force

52
00:01:55,830 --> 00:01:53,119
that the bungees are pulling down it'll

53
00:01:57,590 --> 00:01:55,840
record our footfalls and so then on the

54
00:01:59,510 --> 00:01:57,600
ground we can actually use that analyze

55
00:02:01,510 --> 00:01:59,520
it and see how i'm doing in my workouts

56
00:02:03,990 --> 00:02:01,520
and so when we're ready to go

57
00:02:07,429 --> 00:02:04,000
all we have to do is uh hit the start

58
00:02:26,949 --> 00:02:08,550
and

59
00:02:31,350 --> 00:02:28,949
so that gives you a little sense of how

60
00:02:32,790 --> 00:02:31,360
we get to use the treadmill up on orbit

61
00:02:34,070 --> 00:02:32,800
i've done a lot of training with it down
