Abstract

1.
1. The duration of the exercise was found to be important in producing fibre hypertrophy than the intensity.
2.
2. Long duration exercise caused significant fibre hypertrophy whereas short duration exercise caused significant hypotrophy.
3.
3. These changes in fibre diameter were accomplished after 19 days.
4.
4. Swimming exercises caused no significant changes in fibre diameter.
5.
5. The increment in oxygen consumption was used as an indication of the the work done during exercise.

Quadriceps Exercises for Osteo-arthritis of the Knee — A Single Case Study Comparing Short-term versus Long-term Training Effects
1994, Physiotherapy (United Kingdom)
This single case study compared the strengthening effect of a short-term (six-week) versus a long-term (13-month) quadriceps strength training regimen for one 58-year-old woman diagnosed as having osteo-arthritis of the knee who was not receiving any other form of intervention.
The strengthening regimen was initially carried out three times a week for six weeks under supervision using a standardised protocol of six bi-lateral maximal isometric quadriceps contractions at an angle of 60°. After a six-week detraining period, the same exercises were carried out in a similar manner at home for a further 13 months.
The results indicated that the isometric exercises were associated with a 40% increase in maximal isometric quadriceps torque at six weeks, a 10% torque decline with detraining, with an additional torque increase of 30% after 13 months of further training.
Based on these findings, it is suggested that isometric quadriceps exercises carried out over a protracted period for the treatment of mild knee joint disease could improve the efficacy of this treatment.
Effects of chronic rotation and hypergravity on muscle fibers of soleus and plantaris muscles of the rat
1975, Experimental Neurology
Three lines of F₃ Sprague-Dawley rats derived from a single mating were raised either outside the centrifuge at earth gravity (earth control), or under chronic rotation in the center of the centrifuge at 1.03g (rotation control), or in the rim of the centrifuge at 2g (rotation experimental). The rats were killed at 3 months of age, and serial sections of plantaris and soleus muscles were stained for succinic dehydrogenase activity, and for actomyosin ATPase activity following preincubation at pH 10.2. Muscle fibers in a cross-sectional unit area of soleus and both the superficial and deep regions of plantaris were identified as to fiber type according to an enzyme profile and counted. The proportion of each fiber type was calculated, and the diameter of 24 fibers of each type was measured. Analysis of variance was used to determine the effect of experimental treatment and sex on populations and diameters. In soleus, the fiber population shifted from 82% slow oxidative fibers in the controls to 100% slow oxidative fibers in the rotation experimentals in response to the stress of hypergravity. In plantaris, chronic rotation resulted in an increase in fast glycolytic fibers and a corresponding decrease in fast oxidative glycolytic fibers, in both the rotation control and experimental rats. The population changes were similar in both sexes. Muscle fiber diameters were similar in both controls, indicating no response to the stress of chronic rotation. A sexual dichotomy was noted in response to hypergravity, with muscle fiber diameters increasing in females, but decreasing in males.
