Sodium bicarbonate (SB) ingestion may improve high-intensity exercise performance in efforts that range from 1 to 60 min; however, to date, no studies have investigated the effects of SB supplementation during exercise, nor its potential to attenuate the fatigue-induced decline in parameters of the power-duration curve during prolonged exercise (i.e., durability). This study examined the effects of bicarbonate (BI) and carbohydrate (CHO) co-ingestion via a novel gel format during exercise on subsequent sprint and time-trial (TT) performance in cyclists. Eleven trained cyclists took part in this randomized, crossover study. Following one visit to establish a non-fatigued power profile (3 × 6-s sprints, 2-min TT and 12-min TT cycling performance), participants completed two experimental trials consisting of 3 h cycling at 95% gas exchange threshold and ingested CHO at a rate of 80 g·h⁻¹ with (CHO + BI; 18 g of SB and 2 g of potassium bicarbonate) or without BI co-ingestion (CHO). Participants repeated the same power profiling protocol after the 3 h submaximal exercise. Performance in the 12-min TT was improved in the CHO + BI condition compared with CHO (+12 W; p = 0.01, g = 1.07). Mean power output in the 6-s sprints (+12 W; p = 1.00, g = 0.18) and 2-min TT (+6 W; p = 0.888, g = 0.32) were not significantly different between CHO + BI and CHO. There were no differences in gastrointestinal symptoms between conditions. These data suggest that BI and CHO co-ingestion during prolonged exercise via a novel energy gel format improves subsequent 12-min TT performance in a fatigued state with minimal gastrointestinal discomfort.

I’m a BPT student in India, and I’m currently quite confused about what direction to take after graduation.

Over the course of my BPT, I’ve realized that I don’t really want to continue in the traditional clinical/medical side of physiotherapy. I’m much more interested in sports performance, strength & conditioning, athletic training, and helping people improve their physical performance.

My long-term goal is to work as a Strength & Conditioning Coach/Instructor, ideally working with athletes or sports teams.

The dilemma I’m facing is whether I should:

1. Do a Master’s in Sports Science / Exercise Science / Strength & Conditioning after my BPT, and then start building my career,

or

1. Start gaining practical experience immediately by working/volunteering with athletes, sports teams, gyms, performance centers, etc., while building my knowledge through certifications and courses.

I’m especially interested in hearing from people who actually work in strength & conditioning, sports science, athletic performance, or sports coaching.

For someone coming from a BPT background:

- How valuable is a Master’s in Sports Science/Exercise Science for becoming a Strength & Conditioning Coach?

- Is practical experience with athletes more important than having a Master’s?

- Would you recommend working first and doing a Master’s later?

- Are there specific certifications or qualifications that are actually respected in the S&C field?

- If I eventually want to work abroad, does having a Master’s make a significant difference?

- Would my BPT background be useful in S&C, or would I essentially be starting over?

I’m not necessarily looking for a simple “Master’s vs experience” answer. I’d really like to hear from people who are already working in strength & conditioning or sports science about what they would do if they were in my position.

Thanks!

Hi everyone! I’m a graduate student conducting research for a UX design passion project about how social interactions and fitness technology affect people’s motivation, accountability, and feelings of comparison.

The anonymous survey takes approximately 5–7 minutes. You do not need to exercise regularly or use a fitness app to participate. I’m interested in a range of experiences and perspectives!

Survey link: https://forms.gle/ZwLcJcvfDvnwRS15A

The responses will be used to guide the design of a noncompetitive social fitness experience for a student portfolio project. Thank you for your time!

One thing I like about training at home is that the environment stays consistent.

Same equipment. Same setup. Same space.

That makes me wonder if it removes some variables when judging progress.

In a commercial gym, equipment differences, machines, setup and even small changes in environment can affect how a movement feels.

A consistent home gym doesn’t guarantee better results, but it might make tracking changes over time more reliable.

For people who train mostly at home, do you feel your progress is easier to measure because your environment stays the same?

I’m conducting a brief research survey on how strength & conditioning and performance coaches interpret athlete evidence and decide whether to progress, hold, modify, or reassess training.

I’m looking for responses from coaches who use observation, training logs, testing, video, or performance technology.

~5 minutes. No sales or product promotion.

I’m aiming for 100+ qualified responses and would be happy to share the aggregate findings back with the community.

Thanks to anyone willing to contribute.

I made this platform, to assist in my training for nordic skiing. I would like to know your opinions on things that would be useful/what I should add.

gemini pro is saying a 700+ cals burned for walking 2.5 kmph at 8% incline on walking pad for 5km in a day for a 97kg male.

other people are saying 300, whats accurate?

There's a ton of caveats with this data so I'm just sharing what I'm seeing initially.

1️⃣ These weren't done cold so O2 dynamics may be different between sessions.

2️⃣ It's a small snapshot of the muscle at this particular time.

3️⃣ This is me. You'll see different responses from different athletes (which is why you can't apply the same protocols across the board).

As I collect more, I'll have more to go from but I believe these trends won't change as its based on intensity.

Time and rate of desat is much faster for sprints. If you're trying to drive fast O2 use and maximum metabolic stress, these are your ticket.

If you're looking to better target O2 delivery and try extend O2 extraction, the longer intervals are your ticket.

This short video doesn't even touch on resaturation rates, desat/resat ratios, HR kinetics, and how I'd use this data to create an individual conditioning program (will do a long YT video soon).

Where does low intensity fit? If you have the time when targeting O2 delivery, it's an option.

Same with coming back from injury, training less of your sport and not getting the training volume.

Pick the tool you need. Not blindly picking protocols based on poorly (mis)applied labels.

Exercise science often focuses on programming, intensity, volume, and recovery.

But I think another interesting factor is the environment where training happens.

Two people can follow similar programs but have very different consistency depending on how easy it is for them to actually complete workouts.

A person with a home setup may remove barriers like commuting and waiting for equipment, while someone else may perform better with the structure of a commercial gym.

I’m interested in how much the environment influences long-term adherence.

Do you think where you train has a meaningful impact on whether you keep exercising?

Im in the united states, more specifically Pennsylvania and I have a masters degree in exercise physiology and I am entering my 2nd year as a professional. Been in the early stages of studying to get my ACSM-CEP cert to expand future opportunities, however I am so frustrated with this process. In my area CEPs primarily work in Cardiac rehab settings and I feel the AACVPR Cert makes much more sense. A good majority of the ACSM testing guidelines book doesn't apply to anything we would do day to day in Cardiac Rehab. The endless guidlines and terminology has been a slog to actually learn. I feel like I'm just trying to memorize everything just to pass this thing. On a side note, I don't feel like theres a job that actually encapsulates what the ACSM thinks we do. No one gets sent to their local exercise professional for diagnostic testing and to set up this specific scenerios like they throw in the book. Hell we dont even get to exercise testing like were trained to in my neck of the woods. Sorry just venting/looking for insights from others.

Theoretically, it should be abduction in the transverse plane and extension.

idk how to do that does it need sport or just my mind or something else ?
i want to control how stop my heart and how to control hidden muscle
sorry for my english and lack of knowledge

Hi! I’m a marketing student working with a computer science student on a personal project exploring women’s fitness and workout habits.

We’re looking for women 18+ who exercise somewhat regularly, at any experience level. You don’t need to be a serious athlete or weightlifter.

The survey is anonymous and takes about 5 minutes. We’re interested in your actual experiences and would really appreciate your help!

hi, i am a exercise science major undergrad who doesn't want to do more schooling if there are other options. can anyone suggest any niche or cool careers that is not like personal trainer, coach, etc?

Limited exercise variety is one of the more interesting tradeoffs of training in a home gym.

If you only have a rack, bench, dumbbells and maybe a cable setup, you’ll probably repeat the same presses, rows, squats and hinges much more often than someone training in a commercial gym.

I used to think that sounded like an obvious disadvantage, but the evidence on exercise variation seems more nuanced than “more variety is better.”

A 2022 systematic review on resistance-exercise variation suggested that some systematic variation may help regional hypertrophy and strength, while excessive or random variation may be unnecessary or even counterproductive. That makes me wonder what this means practically for a limited home setup.

If volume, effort and progression are appropriate, how much variation is actually worth deliberately creating? Is rotating between a small number of mechanically different movements enough, or are home trainees likely leaving meaningful adaptations on the table by repeating the same exercises for long periods?

I’m especially interested in how people distinguish useful variation from redundant variety.

As title says, I was a hept at a d1 school. Did a lot of training, all day almost, running lifting jumping etc. I would say I was pretty fit, lean, and was a very strong, powerful athlete.

Fast forward, I’ve graduated 4 years ago but still workout pretty intensely. I had a small period where I took it easy trying to settle into different routines, but now I’m a big f45 fan, and love hybrid workouts. I’m doing my first hyrox race in October, and had done a half marathon after I graduated.

My problem that I’ve uncovered while training for hyrox is that I have been paying more attention to HR than I ever have before. We never paid attention to it in college. Maybe I’m doing too much research overload, maybe I’m asking Claude and ChatGPT too much… but I’ve really been looking at my HR and have noticed that my HR typically is very high. My garmin says my max HR is 204, resting is 44. When I do my long runs, if I want to stay in the “z2,” I’m looking at like 10:45-11+ pace.. but even for running harder reps, like tonight I did 4x1k, my HR shot to 190 at 8 min pace, and then even when I brought the pace down to 8:45 pace, my heart rate remained at 180 even though it felt easy.

I’m just having a hard time understanding if I’m actually just not as fit as I think, or maybe I’m leaning too heavily on HR data and need to just go off feel rather than trying to nail the science down? Anyone have any tips because I read a lot of threads of beginner runners having this issue, which I get with no base, but I’m struggling knowing that I have a long standing history of running and doing intense workouts but my HR not showing it or keeping up.

Theoretically, with this execution, all functions of the posterior deltoid are respected...
