“…In future investigations, these differences might be avoided by using more accurate descriptors to define each type of training modality. 95 Despite the efforts made to include only studies in which the eccentric part of the movement was isolated, this was not always possible. Both eccentric and concentric actions are repeated cyclically during normal human locomotion, and, therefore, it is difficult to isolate one phase from the other.…”

Purpose: The capacity of eccentric actions to produce muscle hypertrophy, strength gains, and neural adaptations without stressing the cardiopulmonary system has led to the prescription of eccentric training programmes in patients with low tolerance to exercise, such as elders or those with chronic health conditions. The purpose of this systematic review was to analyze the evidence regarding the effectiveness and suitability of eccentric training to restore musculoskeletal function in patients with chronic diseases. Summary of Key Points: Relevant articles were identified from nine databases and from the reference lists of key articles. Articles were assessed to determine level of evidence and scientific rigour. Nine studies met the inclusion criteria. According to Sackett's levels of evidence, 7 studies were graded at level IIb, 1 study at level IV, and the remaining study at level V. Articles were also graded for scientific rigour according to the PEDro scale. One study was rated as high quality, 4 studies were rated as moderate, and 2 studies were graded as poor quality. Conclusions: Eccentric training may be safely used to restore musculoskeletal function in patients with some specific chronic conditions. However, the heterogeneity of diseases makes it very difficult to extrapolate results and to standardize clinical recommendations for adequate implementation of this type of exercise. More studies are needed to establish the potential advantages of eccentric training in chronic conditions.

“…This will also help to get an idea how to implement research results into real life settings. For strength training, the scheme of Toigo and Boutellier [8] is helpful. In general, emphasizing the methods section of a paper may enlarge it.…”

“…Therefore, it is not surprising that studies containing some sort of strength training lead to contradictive results or are not comparable. Toigo and Boutellier [8] identify new determinants and recommend to standardize the design and description of all future resistance exercise investigations by using a set of 13 mechanobiological determinants (classical and new ones), including fractional and temporal distribution of the contraction modes per repetition, duration of one repetition, rest in-between repetitions, time under tension, muscular failure, range of motion, recovery time, and anatomical definition.…”

“…The conventional of exercise-induced hypertrophy subsequent with the effect of traditional (RT) program results from an increase of sarcomeres and myofibrils [25]. A serial increase in sarcomeres results in a given muscle length corresponding to a shorter sarcomere length [29]. In particular, bodybuilders tend to display a greater proliferation of fibrous endomysial connective tissue and greater glycogen content compared to power-lifter athletes [22], Even though sarcoplasmic hypertrophy is often described as non-functional, it is plausible that chronic adaptations associated with its effects on cell swelling may mediate subsequent increases in protein synthesis that lead to greater contractile growth.…”

Introduction: Underweight (UW) individuals face lot of problems in increasing muscle size and also increasing body weight and fitness levels. Resistance training (RT) plays a very important role in increasing hypertrophy of the muscles one and all in general. (ACSM, 2009) stated that the resistance exercise for healthy adults provides program design recommendations for muscle hypertrophy [3]. The purpose of this study is to find out the influence of low, Medium and high intensity of (RT) on the muscular hypertrophy and selected health related fitness variables among the underweight males. Method: A group of (N=40) subjects was selected randomly to participate in this study. The age of the participants was in the range of 18-24 years, (RT) program was employed for 12 weeks, two days in a week, 45 minutes of training per session. The subjects were segregated into two groups namely Group-A (n=20, experimental group), Group –B (n=20 control group). The (RT) was employed on experimental group. Control group was not given any above mentioned special training program. The tests (pre and post) considered for this study was health related fitness variables are as follows; body composition, muscular strength, muscular endurance, Flexibility and cardio-vascular endurance. And test for muscular hypertrophy i.e. (neck, shoulders, chest, arms, waist, hips, thigh and calf; To compare the mean differences from pre to post test, mean, standard deviation, and t-test was computed by the help of statistica software. Results & Discussion: 12 weeks of training protocol had revealed significant performance from pre to posttest among the subjects with regard to the selected fitness variables and presented by percentages i.e. BMI (4.45%), bench press (35.12%), sit-ups test (22.34%), sit & reach test (26.83%), and 12 min run & walk test (26.94%). Furthermore the muscular hypertrophy was enhance among the underweight students i.e. Neck (2.61%), shoulder (2.95%), chest (6.75%), arms (10.43%), waist (8.23%), thighs (11.15%), calves (4.08%) ; and lastly hip circumference by (3.33%) had shown reduction in size from pre to post test. Conclusion: It is concluded that the influence of training had shown significant performance among the (UW) students with regard to the selected fitness test i.e. (BMI), bench press, sit-ups test, sit & reach test and 12 min run & walk test. Furthermore the selected muscular hypertrophy of the (UW) students i.e. Neck, shoulder, chest, arms, waist, thighs, calves circumference had shown increased in the muscular size and hip circumference had shown reduction in size from pre to post test.
