Challenging the American College of Sports Medicine 2009 Position Stand on Resistance Training

Background:To examine the effectiveness of the American College of Sports Medicine (ACSM) and the American Heart Association (AHA) resistance training (RT) guidelines to improve physical function and functional classification in older adults with reduced physical abilities.Methods:Twenty-five at-risk older adults were randomized to a control (CON = 13) or 8-week resistance training intervention arm (RT = 12). Progressive RT included 8 exercises for 1 set of 10 repetitions at a perceived exertion of 5–6 performed twice a week. Individuals were assessed for physical function and functional classification change (low, moderate or high) by the short physical performance battery (SPPB) and muscle strength measures.Results:Postintervention, significant differences were found between groups for SPPB—Chair Stand [F(1,22) = 9.14, P < .01, η = .29] and SPPB—Total Score [F(1,22) = 7.40, P < .05, η = .25]. Functional classification was improved as a result of the intervention with 83% of participants in the RT group improving from low to moderate functioning or moderate to high functioning. Strength significantly improved on all exercises in the RT compared with the CON group.Conclusions:A RT program congruent with the current ASCM and AHA guidelines is effective to improve overall physical function, functional classification, and muscle strength for older adults with reduced physical abilities.

Objective: To accurately quantify percentage changes in strength gains and correlate it with percentage changes in plasma myostatin levels. Study design: Same Subject Experimental Study. Setup: Faculty of Sports Medicine and Physiotherapy, Guru Nanak Dev University, Amritsar, India. Method of study: We used a longitudinal experimental design in which our subjects were assessed before and after the resistance training programs designed to induce muscle hypertrophy. A total of 18 subjects were selected, including both males (N = 15) and females (N = 3), to begin the study. Subjects were given circuit resistance training program for a period of six weeks. Subject's maximal isometric voluntary contraction for both the limbs knee extensors and flexors were measured using HUR 5340 Leg Extension/curl computer controlled machine prior to the training and after the training. The plasma myostatin levels were determined by ELISA analysis. Results: We have found a strong negative correlation of -0.73 (p < 0.01) and -0.75 (p < 0.05) between percentage change in plasma myostatin and percentage peak torque gains in bilateral knee extensors and flexors, respectively. Conclusion: Myostatin is negatively correlated to the strength gains in the bilateral knee extensors and flexors with resistance training.

Physical Medicine

For rehabilitation and sports medicine, resistance training (RT) has been known to increase muscle strength. Several latest reports showed the changes in muscle and fat tissues by RT and endurance training (ET). Systematic review and meta-analysis from 58 papers included about 3000 subjects, 45-60min session, 2.7 times a week and 5 months. As a result, RT group showed 1.46% reduction in body fat, which is equivalent to 0.55kg of fat mass. When one emphasizes the weight result by the scale, clinical effect of RT cannot be evaluated correctly, because RT brings increased muscle mass and decreased fat mass.

Essential Components

IntroductionLimb muscle dysfunction is a common manifestation in patients with chronic obstructive pulmonary disease (COPD). Optimising of limb muscle function is therefore an important goal during pulmonary rehabilitation of patients with COPD. Resistance training (RT) is the best available intervention to achieve this goal. Previous systematic reviews on RT primarily focused on methodological quality. However, the intervention holds the essence of each experimental study. Replication of RT interventions requires clear, complete and accessible reporting of the essential components. The American College of Sports Medicine (ACSM) provides evidence-based guidelines for RT prescription and recommends RT models specific to desired outcomes, that is, improvements in strength, muscular hypertrophy, power or local muscle endurance. The aim of this review is to investigate if the application of the RT principles and key training variables is described sufficiently in current evidence on the effects of RT interventions in patients with COPD.Methods and analysisAny research study (randomised, non-randomised controlled, controlled pre–post studies and observational studies) with an RT intervention in patients with COPD will be considered for this systematic review. Potentially relevant studies published in English from inception to 1 October 2017 will be identified from Embase, Cochrane Library, Cumulative Index of Nursing and Allied Health Literature (CINAHL) and Physiotherapy Evidence Database (PEDro). Studies exploring the effects of RT following a single session and RT interventions limited to other respiratory chronic diseases will not be included. Additionally, studies including non-COPD participants will be excluded, if the COPD data are not separated. Pairs of reviewers will independently extract data using data collecting sheets. Quality appraisal of RT description will be performed in timeframes according to the latest published ACSM position statement on exercise or RT.Ethics and disseminationThis protocol is a systematic review and therefore ethical approval is not required. The results of this review will be disseminated through peer-reviewed publication and presented at scientific conferences.PROSPERO registration numberCRD42017067403.
