Article: Evidence-Based Resistance Training Recommendations
[show abstract] [hide abstract]
ABSTRACT: Resistance training produces an array of health benefits, as well as the potential to promote muscular adaptations of strength, size, power and endurance. The American College of Sports Medicine (ACSM) regularly publish a position stand making recommendations for optimal achievement of the desired training goals. However, the most recent position stand (as well as previous ones) has come under heavy criticism for misrepresentation of research, lack of evidence and author bias. Therefore this paper proposes a set of scientifically rigorous resistance training guidelines, reviewing and summarising the relevant research for the purpose of proposing more logical, evidence-based training advice. We recommend that appreciably the same muscular strength and endurance adaptations can be attained by perform-ing a single set of ~8-12 repetitions to momentary muscular failure, at a repetition duration that maintains muscular tension throughout the entire range of motion, for most major muscle groups once or twice each week. All resistance types (e.g. free-weights, resistance machines, bodyweight, etc.) show potential for increases in strength, with no significant difference between them, although resistance machines appear to pose a lower risk of injury. There is a lack of evidence to suggest that balance from free weights or use of unstable surfaces shows any transfer-ence to sporting improvement, and explosive movements are also not recommended as they present a high injury risk and no greater benefit than slow, controlled weight training. Finally, we consider genetic factors in relation to body type and growth potential.Medicina Sportiva Med Sport. 01/2011; 15:147-162. -
Article: Influence of vibration training on energy expenditure in active men.
[show abstract] [hide abstract]
ABSTRACT: The aim of the present study was to analyze the effect of whole-body vibration on energy expenditure, as well as on exercise intensity, during and immediately after a typical set of exercises for muscle hypertrophy in physically active subjects. Seventeen male university students (mean age 18.3 +/- 0.24 years) volunteered to perform 2 different training exercises: half squat (HS), and half squat with vibration (HSV). Both exercises were performed by all subjects on the vibration platform (with vibration only for HSV), the sequence order being assigned randomly. Energy expenditure (EE), respiratory exchange ratio, perceived exertion (PE), and heart rate were recorded for baseline, exercise, and short-recovery conditions. Training consisted of 5 sets of 10 repetitions of HS and HSV, with a 2-minute recovery interval between sets. Analysis of variance with repeated measurements and Bonferroni correction, as well as effect size were used for statistical calculations. Results indicated that EE and PE were significantly higher in the HSV group, during both exercise and recovery. Heart rate did not differ significantly between groups. Thus, it would appear that HS strength training could be rendered more energy-efficient through the addition of vibration. Moreover, it would be feasible to introduce vibration exercises into regular training programs, particularly those whose key objective is muscle hypertrophy along with fat reduction.The Journal of Strength and Conditioning Research 06/2007; 21(2):470-5. · 1.83 Impact Factor -
Article: Psychological benefits of virtual reality for patients in rehabilitation therapy.
[show abstract] [hide abstract]
ABSTRACT: Whether virtual rehabilitation is beneficial has not been determined. To investigate the psychological benefits of virtual reality in rehabilitation. An experimental group underwent therapy with a virtual-reality-based exercise bike, and a control group underwent the therapy without virtual-reality equipment. Hospital laboratory. 30 patients suffering from spinal-cord injury. A designed rehabilitation therapy. Endurance, Borg's rating-of-perceived-exertion scale, the Activation-Deactivation Adjective Check List (AD-ACL), and the Simulator Sickness Questionnaire. The differences between the experimental and control groups were significant for AD-ACL calmness and tension. A virtual-reality-based rehabilitation program can ease patients' tension and induce calm.Journal of sport rehabilitation 06/2009; 18(2):258-68. · 1.07 Impact Factor
