Hypertrophy training adaptations -
While protein synthesis rates were measured herein, it is notable that muscle protein breakdown rates were not assessed. The former are commonly measured, whereas the latter are rarely measured given the technical challenges that are often cited [reviewed in Tipton et al.
We speculate that protein breakdown rates are likely volume-dependent, and over longer time courses i. However, no data exist supporting this contention, and this needs to be formally assessed. In spite of collecting training volume throughout the course of the study, we lack time under tension data and this would have been insightful to include in the current dataset.
In spite of this limitation, Jenkins et al. Thus, while we lack these data, we suspect that our participants experienced time under tension stimuli between legs. A final limitation of the current study is the length of training as well as our programming.
In this regard, we posit that the training status of the cohort in the current study may have precluded our ability to detect any meaningful training adaptations over the 6-week training period. With regard to programming, we contend that a strength includes the real-world applicability; namely, HV and HL load progressions would likely follow similar patterns in recreational gym-goers.
However, limitations to our approach include a priori programming being a bit arbitrary as well as weekly volume loads being more accelerated in the HV versus HL condition. In conclusion, HV training elicited VL hypertrophy, whereas HL training resulted in a greater increase in leg extension strength.
The current data challenge our prior muscle-molecular findings given that no alterations were observed in myosin heavy chain and actin protein abundances following either training protocol. However, the current iNon-MyoPS findings suggest some muscle-molecular differences exist between HV and HL training and warrant further research.

Practical Application: A Resistance Training Prescription for Health It is evident from a number of the adaptations that occur with resistance training that there are several health-related benefits.
Resistance training has been shown to reduce factors associated with coronary heart disease, diabetes and osteoporosis. Further research is needed to elucidate the effects of resistance training on blood lipids, lipoproteins and blood pressure in hypertensives , and to ascertain what type of training programs may best alter these risk factors.
From this overview, there are some practical guidelines for the health fitness professional and personal trainer who wish to prescribe resistance training programs for health status improvement.
They are as follows: 1. Develop programs that will utilize a greater amount of energy expenditure during the workouts. Programs that utilize the larger muscle groups provide a structural basis for the preferred loading that is recommended for improvements in bone mass and mineral density.
This will also contribute to the caloric cost of the programs, helping to facilitate weight management goals. Use moderate intensity programs, with multiple sets of 8 to 12 repetitions Stone et al.
A frequency of 2 - 3 times a week of resistance training appears applicable and attainable. Programs designed to increase total workout volume total repetitions x weight are encouraged.
As with any effective exercise prescription, individualize the program, with a carefully planned, progressive overload. Be guarded in the use of isometric contractions and high-intensity load training due to the marked increase observed in diastolic and systolic blood pressure.
Incorporate a variety of exercises. In order to avoid the effects of overtraining, muscle soreness, and injury, a prescription of resistance training using a variety of exercises is prudent.
With certain organic conditions, such as musculoskeletal conditions i. Take the time to teach the correct performance techniques of the resistance exercises. In the methodology sections in a number of the studies, the researchers emphasized the importance of teaching the subjects safe and correct resistance training mechanics.
Be aware that the training demands of resistance training may be greater for novice, low-fitness level, and elder individuals, due to the unique physiological challenges of the activity, and the level of fitness of the individuals.
Often times, the use of longer rest periods between sets may be beneficial to help these populations adapt to the training demands. Multiple-joint exercises are more demanding than single-joint exercises, and thus suggest that the training frequency days per week may need to be provide adequate recovery up to 48 hrs for the clients, especially when just beginning a resistance training program.
Develop an effective dialogue with your students. In an attempt to keep the training regimen satisfactory for the study, some researchers mentioned the importance of communication with the subjects in order to sustain the investigation.
Effective communication is also consequential in developing and maintaining effective training programs for your students. References : Behm, D. Velocity specificity of resistance training.

Body Gut health solutions adxptations strength tests were performed at each testing session, and Adaptatinos assays were performed on muscle tissue after study completion. Two-way within-subject repeated measures ANOVAs were performed on most dependent variables, and tracer data were compared using dependent samples t-tests. Six-week integrated non-myofibrillar protein synthesis iNon-MyoPS rates were also higher in the HV versus HL condition, while no difference between conditions existed for iMyoPS rates. No interactions existed for other strength, VL morphology variables, or the relative abundances of major muscle proteins.

To achieve different results, you need to make modifications to your resistance program by making changes to what is known as the acute training variables.
