The primary aim of this study was to systematically compare the effectiveness of blood flow restriction training (BFR) versus traditional resistance training (TRT) to improve muscle size in healthy adults. Secondary outcomes were improvements in muscle strength and endurance. We performed a systematic searchwithmeta-analysis. Using predetermined criteria, 541 unique articles were identified through databases and bibliographies. After screening titles, abstracts, and full texts, 20 articles were included in the review. All 20 articles evaluated muscle hypertrophy, 19 evaluated strength, and 1 evaluated endurance in response to BFR and TRT. Data from 10 articles were included in the meta-analysis. In the qualitative analysis, TRT and BFR increased muscle size without differences between conditions for at least 1 hypertrophy outcome in 13 studies, and TRT or BFR differentially improved hypertrophy in 5 studies. TRT and BFR increased strength without differences between conditions for at least 1 outcome in 15 studies, and TRT or BFR differentially improved strength in 9 studies. Results from the meta-analysis indicate no differences in muscle size (ES 5 0.045, 95% CI [20.278 to 0.367]) or strength (ES520.149, 95% CI [20.439 to 0.141]) improvements with BFR versus TRT. Practitioners can implement BFR training to increase muscle size and strength as appropriate, especially for training periods of 8 weeks or longer.

Resistance training (RT) is a nonpharmacological complement to cancer treatments due to its effectiveness in attenuating sarcopenia, cardiotoxicity, fatigue, and emotional disorders common in oncology patients. To adequately program and evaluate the acute or long-term effects of this type of training, a proper evaluation of the patients’ strength levels is necessary. Strength evaluations traditionally applied to this population required reaching muscle or technical failure, which could increase their discomfort levels, risk of injury, or other complications associated with the disease. In this regard, this manuscript described different dynamic and isometric evaluations recommended to accurately and safely evaluate the strength of the oncology population. Concerning dynamic evaluations, the velocity based method is recommended to determine the capacity of the patient to apply force against maximal (i.e., 1 repetition maximum) and submaximal loads. The sit-to-stand or vertical jump tests are also proposed as alternatives to evaluate dynamic strength using body weight. For isometric assessments, the knee extension and handgrip tests could complement dynamic evaluations or replace them for patients with very low strength levels. Besides describing in depth the aforementioned evaluations, the current review proposes important methodological aspects to ensure their accurate, reliable, and safe implementation.

The use of exercise interventions to maximize athletes’ performance is a common practice in competitions. This systematic review aimed to compile research that explored the effectiveness of priming strategies to maximize physical performance in track and field. The literature search was conducted from PubMed and Scopus. One hundred eighty-two studies were assessed against the inclusion criteria: (a) minimum 1-year participation/competition experience; (b) randomized controlled trials with pre-post intervention outcomes; and (c) studies involving exercise interventions applied #6 hours before outcome measures were collected. Fifteen studies satisfied the criteria and were categorized according to the exercise interventions used (i.e., resistance training, plyometric/ ballistic training, resisted sprints, and modified warm-ups). Heavy-loaded resistance training (i.e., .85% 1 repetition maximum) and resisted sprints increased subsequent sprint performance. Plyometrics/ballistic training also positively impacted subsequent jumping (i.e., long jump) and throwing performance (i.e., shot put). Modified warm-ups (i.e., high-intensity sprints and heavier throwing implements) also improved subsequent running and throwing performance. Overall, exercise interventions performed at high intensity and low volume augment subsequent physical performance as close to 4 minutes before the event. However, a sufficient recovery interval must be considered for a positive performance response.

From the 2021 Personal Training Virtual Conference, Andrea Leonard thoroughly details the impact of various cancer surgeries on muscle balance and range of motion and necessary program considerations. She also discusses the acute and chronic side-effects of cancer treatment and how they may affect exercise programming. Another area that is highlighted is lymphedema. She details the cancer-related risk factors and how it can be prevented and/or managed with proper exercise programming and progression.
