http://www.swimsmooth.com/strokerate.html
Most TI swimmers are emphasizing stroke count or strokes per length, and
thinking the lower the stroke count the better.
However now I'm thinking maybe I should concentrate on SPM, strokes per
minute, first.
This video is saying 76 spm is the magic stroke rate!

the stroke would be more efficient, and then the stroke count (strokes per

Background and Purpose— The role of anticoagulant treatment for acute
cardioembolic stroke is uncertain. We performed an updated meta-analysis of
all randomized trials to obtain the best estimates of the efficacy and
safety of anticoagulants for the initial treatment of acute cardioembolic
stroke.
Methods— Using electronic and manual searches of the literature, we

fine, then I just drop back down to my normal cruising pace after a

The breaststroke is the slowest stroke!
Swimmers are "belly-down" and use a simultaneous arm pull, with the arms
pressing out (a "Y" shape), then sweeping in, with the hands meeting under
the face then extending forward. The elbows must be underwater during the
pull and the hands are not allowed to pull past the waist/hips (with one
exception on pullouts).

发帖数: 1995 | 28 今天第一次拿出来pull buoy试着pull了几个length，很快掌握了平衡。
计了一下50米的时，大概我kick是122"左右，pull是62"左右，full stroke是52"。大
致上pull是kick 速度的两倍。这个比例合理吗？
让我觉得意外的是，我的catch-up dill 50米只比full stroke慢4秒，可能是我的滑行
时间还是有点长？
今天间歇游，有一个50米的前25米游进了1m/s的速度，yeah!终于摸到边了！
前一阵发现左手习惯性catch尚未做完全就开始pull，今天着重改善左手的高肘。catch
时左边的肱二头肌有点疼痛。两侧划水都有挤腋下的球的感觉，也感觉划水距离更长了
。还在习惯变长的划水距离，感觉上划水距离变长后有点吃力。今天的划水次数还是9-
10 stroke cycle/length较多，8stroke cycle也出现两次！
出来后摸摸后背，尽管游的时候感觉后背用力了，但摸起来好像没有三角肌那么硬邦邦
的。
下周开始闭馆三周，没有泳游了。:( |

发帖数: 41236 | 29 算不上坏习惯吧，我觉得stroke rate从快变慢难，从慢变快容易..
TI我还是觉得是最好的成人入门练法..
我昨天试了试，为了提高划水效率，的确stoke rate很低，才40/min,
不过我觉得新手的确还是应该以提高dps(或者说降低stroke/length)
为第一目标,stroke/length低，基本表示动作没啥大问题..
我因为以前是玩跑步的，所以体力不是问题，游泳心跳才100左右吧...
你可能动作啥的都基本到位了，剩下就是多练了，只要体力上去了，
