Part II: Training Fast Twitch Muscle Fibers: Why and How |

Written by Ernest W Maglischo

|
Abstract
With the finding that short, intense sprints can improve aerobic capacity (Tabata, et al, 1996), there has been a huge increase in the number of experts who advocate this kind of training over traditional endurance training. Several successful swim coaches are among those recommending more high-intensity training while an equal or even greater number are warning of the pitfalls of training in this manner. A theory is presented in this paper that high-intensity training is essential for improving aerobic endurance. An argument is also presented for a balanced approach to training that includes adequate quantities of moderate-, and low-intensity swimming.

Abstract
This paper reviews methods of identifying and measuring asymmetries in swimmers. A model of factors associated with testing asymmetries in swimming was used as a basis for discussion. The testing includes ‘dry-land' assessment and assessment of the swimmer while swimming.

Swimming Relay Exchange Times: 2008 Olympics |

Abstract
Competitive swimming relay teams with shorter exchange times have been shown to place ahead of teams with equal or shorter swim times. Training relay exchanges to a standardize-time which is shorter than the expected mean has been proposed in order to minimize the possibility of the team being out-placed by teams with average exchange times. This study investigated whether standardized relay exchange time training is consistent with competitive swimming relay performance results.
Swimming relay competition results from the 2008 Beijing Olympics were analyzed using the mean of team relay exchange times. Teams with shorter exchange times (0.52 seconds) out-placed teams with longer exchange times (0.91 seconds). The mean team exchange time for teams other than the above was 0.70 seconds. All three means were significantly (p < .05) different from one another.
Swimming relay performance data from the 2008 Olympics supports training to a standardized relay exchange time. Attainment of this goal may increase the probability that finish places would be based on swimming performance. The training of a team’s relay exchange times should be considered in line with a team’s tolerance for risk taking which may change over a competitive season.

Asymmetries in Swimming: Where Do They Come from? |
|
Written by Ross Sanders, Jacqueline Thow, and Malcolm Fairweather
|
|
Abstract
This paper reviews the causes of asymmetries in swimming. A model of factors related to asymmetries was used as a basis for discussion. Asymmetries can include bilateral asymmetries and muscle imbalances leading to postural changes. The link between asymmetries and swimming performance is highlighted throughout.

Overuse Shoulder Injuries In Swimmers |
|
Written by Theodore J Becker, PhD, RPT, CET, CEAS, CDE, CD A, FACFEI
|
|
Abstract
Shoulder injury is a significant barrier to the training regime and competition experience of the swimmer, both male and female. Both male and female swimmers have a unique potential for the onset of clinical shoulder symptoms. This review of shoulder symptom onset includes information related to growth, stroke biomechanics and signs and symptoms.
