00:00:20,230 --> 00:00:18,710
hey everyone this is mike hopkins nasa

2
00:00:21,910 --> 00:00:20,240
astronaut getting ready to launch the

3
00:00:25,269 --> 00:00:21,920
international space station as part of

4
00:00:26,790 --> 00:00:25,279
expeditions 37 and 38. and i'm in the

5
00:00:29,349 --> 00:00:26,800
countermeasures training room here at

6
00:00:31,429 --> 00:00:29,359
nasa jsc and today i'm going to talk to

7
00:00:33,830 --> 00:00:31,439
you about the exercise bike that we use

8
00:00:36,150 --> 00:00:33,840
up on orbit now right now it looks very

9
00:00:38,709 --> 00:00:36,160
similar to the bike that you might see

10
00:00:40,549 --> 00:00:38,719
in a gym here on earth but in reality

11
00:00:43,270 --> 00:00:40,559
when we get up on orbit it looks quite

12
00:00:45,670 --> 00:00:43,280
different in fact this is a picture of

13
00:00:47,910 --> 00:00:45,680
astronaut jeff williams on orbit and you

14
00:00:49,910 --> 00:00:47,920
can see we don't have the handlebars or

15
00:00:51,590 --> 00:00:49,920
we don't have the seat because you are

16
00:00:52,790 --> 00:00:51,600
able to float so you just have to strap

17
00:00:55,350 --> 00:00:52,800
your feet in

18
00:00:57,029 --> 00:00:55,360
with the with the normal biking shoes

19
00:00:59,029 --> 00:00:57,039
and away you go

20
00:01:01,510 --> 00:00:59,039
now how do we start

21
00:01:04,549 --> 00:01:01,520
well much like the treadmill we actually

22
00:01:06,469 --> 00:01:04,559
have a control uh computer here and

23
00:01:08,230 --> 00:01:06,479
it'll not only give us the the different

24
00:01:10,469 --> 00:01:08,240
workouts that we might have on orbit but

25
00:01:11,990 --> 00:01:10,479
it'll record our heart rate it'll record

26
00:01:13,990 --> 00:01:12,000
what watts we're using what kind of

27
00:01:15,749 --> 00:01:14,000
loads and how fast we're going and so

28
00:01:17,670 --> 00:01:15,759
again we can look at that

29
00:01:18,950 --> 00:01:17,680
at the end of a workout and decide how

30
00:01:21,350 --> 00:01:18,960
well we're doing

31
00:01:22,310 --> 00:01:21,360
and then another little piece much like

32
00:01:27,590 --> 00:01:22,320
the

33
00:01:29,590 --> 00:01:27,600
because again we don't want to impart

34
00:01:31,510 --> 00:01:29,600
these loads into the station

35
00:01:33,990 --> 00:01:31,520
and so the bike is actually mounted on a

36
00:01:36,630 --> 00:01:34,000
rack like this and it has vibration

37
00:01:38,069 --> 00:01:36,640
isolation system as well and that system

38
00:01:39,749 --> 00:01:38,079
is these springs and so there will be

39
00:01:42,069 --> 00:01:39,759
springs at each of these corners and

40
00:01:44,469 --> 00:01:42,079
they're basically designed

41
00:01:46,870 --> 00:01:44,479
to absorb the load as you're biking a

42
00:01:48,789 --> 00:01:46,880
little interesting tidbit here

43
00:01:50,469 --> 00:01:48,799
so on orbit when they first started

44
00:01:52,310 --> 00:01:50,479
using this there was a lot of times when

45
00:01:54,550 --> 00:01:52,320
this spring would bottom out

46
00:01:56,149 --> 00:01:54,560
and so to overcome that well

47
00:01:58,230 --> 00:01:56,159
they found a good use for dirty old

48
00:02:00,550 --> 00:01:58,240
socks and uh so this we can put right in

49
00:02:03,030 --> 00:02:00,560
the middle there and that'll help us

50
00:02:04,950 --> 00:02:03,040
keep from bottoming out and so again

51
00:02:07,109 --> 00:02:04,960
this is our exercise bike that uh that
