“…Thus, with concurrent contraction (plantarflexion) during push-off (an eccentric contraction) greater forces will be exerted, 28 and therefore, increase the likelihood of damage to the musculotendinous structure. [29][30][31] Very recently, Huang et al 32 attempted to develop an animal model of Achilles tendon overuse injury using Soslowsky's shoulder injury protocol. 19 However, their results suggested that the cross-sectional area and biomechanical properties of Achilles tendons from running and nonrunning rats were not significantly different.…”

The purpose of this study was to design an animal model that induces histological changes in Achilles tendons consistent with those cited in the literature for human Achilles tendon disease. Sprague-Dawley rats were subjected to 10 degrees uphill treadmill running on a custom-designed rodent treadmill and at a speed of 17 meters per minute for 1 h, five times per week, over a 12-week treatment period. Subsequent histological analysis revealed alterations in the rat Achilles tendon that were generally consistent with those described in the literature for diseased human tendon tissues. These features include: decreased collagen fiber organization, more intense collagen staining, and increased cell nuclei numbers. Interestingly, though, immunohistochemical cell typing suggests that the observed increased cellularity does not include a significant inflammatory component but is secondary to increased numbers of endothelial cells (i.e., vascularization) and fibroblasts. These histological features likely represent a biological repair/remodeling response resulting from overuse running.

“…One of the challenges ahead, is the pressure and force of exercises which, sometimes, causes injury, such as acute and delayed muscle bruising resulting from unusual exercise, in the athlete and his estrangement from sport and training environment [11,12]. Acute bouts often occur during or immediately after an intense physical activity which, ultimately, causes fatigue, which is mistakenly associated with anemia and the accumulation of metabolic waste [13].…”

Creatine Kinase is an enzyme that consumes and metabolizes energy in the body, especially in the bloodstream. Although this enzyme is found in very low amounts, there are higher levels of this enzyme in different tissues. The main objective of the present study is evaluating the impact of omega 3 supplementation intake on CK index after one session of resistance training in inactive individuals. In this study, 40 patients with inactive women in Karaj, with an average age of 28.16±2.45 years, height 161.58±3.45 cm and weight 59.97±4.30 kg, randomly targeted in four groups of 10 patients (dose groups 2000, 3000, 4000 and placebo) were enrolled. Initially, the subjects participated in a place of resistance training and then practice immediately and 24 hours after their blood samples to estimate the rate of 5cc,LDH serum was used (pre-test). After a period of thirty days omega-3 supplementation in the form of two doses of thousand mg (for 2000), three doses of thousand mg (for 3000), and four doses of thousand mg (for 4000) per day received in capsule form. During this period, the control group received omega-3 free capsules. One day after the supplementation period, the test subjects were taken. For data analysis used from SPSS version 18. The results showed that omega-3 supplementation at a dose of 2000 no significant effect on the level of LDH in women, disabled, immediately after resistance exercise had (P>0.05). But the effect of supplementation with doses of 3000 and 4000 had a significant effect on the level of LDH in non-active women immediately and 24 hours after a resistance training (P<0.05). The effects of doses higher than the dose in 2000 was 3000 and 4000. According to the results, we can say that omega-3 supplementation for a month with a daily intake of 3000 or 4000mg/day for disabled women to be effective.
