Ok, you Endurance Athlete…yes, YOU!\u00a0 I know how much you LOVE your long cardio workouts.\u00a0 I know how much you LOVE your mileage.\u00a0 I know how much you LOVE your volume.\u00a0 I too look forward to my long swims & long runs.<\/p>\n
But we’re all getting older.\u00a0 And that means we absolutely need to shift our focus away from all that enduro training & towards training that targets our fast-twitch muscle fibers.<\/p>\n
So why do aging (“aging” = ANYONE over 30 yrs old) athletes need to train their fast-twitch muscles?\u00a0 Oh my…lots of reasons!\u00a0 But first, a quick tutorial on muscle fiber types (for a visual, here’s a good video<\/a>).<\/p>\n Type 1:\u00a0 Slow Oxidative<\/strong> – These fibers aerobically (i.e., oxygen is used) break down glucose (sugar) into lots & lots of ATP (the muscle’s main energy source).\u00a0 They contract slowly & are highly resistant to fatigue.<\/p>\n Type 2a:\u00a0 Fast Oxidative<\/strong> – These fibers are a combo of Type 1 & Type 2.\u00a0 They use both aerobic & anaerobic (also called “glycolytic”) (i.e. oxygen is not used) means to create ATP.\u00a0 They contract quite strong & fast & will fatigue more quickly than Type 1.<\/p>\n Type 2b:\u00a0 Fast Glycolytic<\/strong> – These fibers produce ATP at the slowest rate via anaerobic glycolysis.\u00a0 As a result, these fibers have the fastest contractions, but also are the quickest to fatigue.<\/p>\n Now that we understand the types of muscle fibers a bit better, let’s move on to why fast-twitch fibers are important…especially for athletes as we age.<\/p>\n So…yep…it’s quite important to maintain your fast-twitch muscles.\u00a0 I’m sure your next question is “How exactly do I train them?”\u00a0 Luckily there are multiple ways…each with pros & cons.<\/p>\n 1. Speed Work\u00a0<\/b>– This is perhaps the most common way that endurance athletes think to train fast-twitch muscles.\u00a0 Although I will say that when endurance athletes tell me they’ve been doing “speed work”…their definition & mine are often different.\u00a0 In my book “speed work” truly means short duration (05-15sec) maximal efforts with long rest intervals.\u00a0 What it is NOT is Tempo work or longer interval training.<\/p>\n Pro:<\/em>\u00a0 Direct transfer to actual sport…you’re doing the sport movements only at a very fast rate.\u00a0 Con:<\/em>\u00a0 High level of injury risk if mobility, technique & base aerobic & strength conditioning are not solid.<\/p>\n 2. Plyometrics<\/strong> – By now most athletes have heard of plyometric (jumping, hopping, bounding, skipping) exercise.\u00a0 These types of movements are focused on explosiveness, speed & power.<\/p>\n Pro:<\/em>\u00a0 Fun, high intensity movements that can transfer well to actual sport.\u00a0 Cons:<\/em>\u00a0 Again, high level of injury risk.\u00a0 Careful consideration must be given to which exercises best match the sport(s).\u00a0 A base level of strength is needed prior to starting a plyo program.<\/p>\n 3. Heavy, Fast Strength Training <\/strong>– The goal is to move heavy weights as fast as possible for a small number of reps (usually 1-6).\u00a0 This is the gym equivalent of sprint training.<\/p>\n Pro:<\/em>\u00a0 Usually done with big powerful exercises like Power Cleans<\/a>, Deadlifts, Squats which work multiple muscle groups.\u00a0 Cons:<\/em>\u00a0 High level of injury risk.\u00a0 Must have excellent joint mobility & perfect technique.<\/p>\n 4. Time Under Tension (TUT) <\/strong>– The exact opposite of #1-3.\u00a0 TUT lifting uses ultra-slow movements to gradually fatigue Type 1, then Type 2a & finally Type 2b fibers.\u00a0 By doing so you can train your fast-twitch muscles with significantly less weight & slow, controlled movement patterns.\u00a0 Key training components of TUT are:<\/p>\n For more info on TUT training, see my Counterintuitive blog post<\/a>.<\/p>\n Pro’s:<\/em>\u00a0 Very safe, very effective.\u00a0 If using machines, technique is less of an injury risk issue.\u00a0 Con:<\/em>\u00a0 This is perhaps the most mentally challenging method.\u00a0 It burns, it hurts, it makes you want to puke!<\/p>\n Over the past year I’ve made it a priority to train my fast-twitch muscles.\u00a0 Here’s how I integrate it…maybe it’ll give you a few ideas!<\/p>\n So, there you have it!\u00a0 If you have questions about how to get started with fast-twitch training…or how to adjust what you’re currently doing…or you’d like some new program ideas…let me know!\u00a0 The key is to just do it.\u00a0 You can’t afford not too!<\/p>\n Happy training!<\/p>\n","protected":false},"excerpt":{"rendered":" Ok, you Endurance Athlete…yes, YOU!\u00a0 I know how much you LOVE your long cardio workouts.\u00a0 I know how much you LOVE your mileage.\u00a0 I know how much you LOVE your volume.\u00a0 I too look forward to my long swims & long runs.
