BFR & Electrostimulation – combining modalities to accelerate injury recovery

November 19, 2019 Snippit Sports Science Podcast

Hi everyone,

This episode builds on the last one which started to look at the role that EMS can assist with strength and muscle gains. The addition of Blood Flow Restriction with EMS prior to this paper hadn’t been investigated so this was a novel investigation.

As always we appreciate the support of Eliteform (www.eliteform.com) so if you are into velocity based training make sure you check them out as I am sure you’ll be excited with their product.

The Effects of Blood Flow Restricted Electrostimulation on Strength and Hypertrophy.

Slysz JT, Burr JF.

J Sport Rehabil.2018 May 1;27(3):257-262. doi: 10.1123/jsr.2017-0002. Epub 2018 May 22.

Abstract

CONTEXT:

The combined effect of neuromuscular electrical stimulation (NMES) and blood flow restriction (BFR) on muscle mass and strength has not been thoroughly investigated.

OBJECTIVE:

To examine the effects of combined and independent BFR and a low-intensity NMES on skeletal muscle adaptation.

MAIN OUTCOME MEASURES:

Subjects had each leg randomly allocated to 1 of 4 possible intervention groups: (1) cyclic BFR alone, (2) NMES alone, (3) BFR + NMES, or (4) control. Each leg was stimulated in its respective intervention group for 32 minutes, 4 days per week for 6 weeks. Mean differences in size (in grams) and isometric strength (in kilograms), between week 0 and week 6, were calculated for each group.

Considerations for optimising BFR pressures during aerobic exercise

October 7, 2019 Snippit Sports Science Podcast

Hi there,

We are finally back – Jared and I have finally synced our schedules to do an episode together. We are trying some new software called SquadCast to try and improve the quality of the internet recording – I think the audio is much better on this episode.

We are quite busy at the moment so we have decided in the short term to push our podcast release to every 2 weeks. Jared in particular is in the back-end of his thesis writing so it is great he is able to take a little bit of his valuable time out to come onto the podcast.

As always we are grateful to our sponsor EliteForm who have integrated Velocity Based Training through the use of 3D camera system with an online Strength planner so please give them a visit at Eliteform.com (Also we forgot to acknowledge them in the introduction so hence our extra shout out here.)

Today’s episode from a practical standpoint helps to understand the optimisation of Blood Flow Restriction pressures when doing aerobic (stationary-based) exercise. I personally have found that dropping my pre-determined BFR pressure by around 20mmHg works best and that if I stayed at this pressure (I usually do my strength training at) it is just doesn’t feel right and is too high. The debate of BFR pressures is an ongoing on and this article helps shed some light as to some great evidence.

Effects of Different Percentages of Blood Flow Restriction on Energy Expenditure.

Pfeiffer PS¹, Cirilo-Sousa MS¹, Santos HHD².

Int J Sports Med. 2019 Mar;40(3):186-190. doi: 10.1055/a-0828-8295. Epub 2019 Jan 31.

Abstract

The study aimed to analyze the effect of different levels of blood flow restriction (BFR) on energy expenditure (EE) and subjective perceptions of discomfort (SPD) during aerobic exercises.

A sample group of 24 young men was required to walk on a treadmill for 14 min at 40% of their maximum speed, with 4 different percentages of BFR (0, 50, 80 and 100%) applied in the lower limbs (LL) once a week with a 7-day interval between the 4 evaluations. EE data were collected during the exercise periods; SPD data were collected after the exercises.

There was a significant increase in EE at 50, 80 and 100% BFR compared to the condition without BFR, and between 50 and 100% BFR; however, there were no differences between 50 and 80% and 80 and 100% BFR. Discomfort showed a significant increase according to the increase in BFR. During the walking exercises with BFR, the EE strongly increased until 50% of BFR; after this level the additional increases slowed.

It can be concluded that when performing aerobic exercises with BFR, there is no need to use BFR levels above 50% to reach satisfying level of EE with only a moderate level of discomfort to the practitioner.

Snippit 44 ► BFR with Dr Christopher Brandner

May 13, 2019 Snippit Sports Science Podcast

Snippit is made possible by listeners like you.

Please help support the podcast:

Hi there, and thanks for tuning in each week.

This week, we are honoured to have first author Dr. Christopher Brandner talking about one his papers currently in the process for publication called:

Muscular Adaptations to Whole Body Blood Flow Restriction Training and Detraining.

We got to cover many topics on BFR aside from his paper.

Dr. Christopher Brandner is a Sports Scientist and Strength and Conditioning Coach at Aspire Academy for Sports Excellence in Doha, Qatar. In 2016, he received his PhD from Deakin University in Melbourne, Australia, where his research examined the acute and chronic training adaptations to resistance exercise with blood flow restriction.
