How to Develop Stronger, Healthier Fingers and Tendons for Climbing

Achy tendons and joints are the bane of hard-training athletes. Sound familiar? Learn the research-based strategy for developing stronger, healthier tendons and pulleys.

For a passionate rock climber, tweaky tendons and sore elbows can stall your training advances—and maybe even ruin your climbing season. Sound familiar?

If so, you’ll be excited to learn that recent research has discovered ways that you can promote healthier and stronger connective tissues! You can delve deeper into the fascinating scientific details by reading the articles under the “Science” dropdown menu at PhysiVantage.com, but here’s the short version.

Tendons Are Plastic, Not Static

Tendons and ligaments have been traditionally viewed as inert structures that did not respond to regular training and nutrition tactics, except in response to injury. Over the last decade, however, researchers have discovered that connective tissues are in fact “smart tissues”. This means they can sense and adapt to chronic mechanical loading. Via specific training and nutritional interventions, climbers can in fact improve the strength of their ligaments, tendons, and muscle matrix. Strength in these areas translates to better performance (via a higher rate of force development and increase muscle efficiency) and reduced injury risk (via increasing collagen synthesis in tendons and ECM). These findings are revolutionary for climbers who train hard and possess the discipline to employ these techniques!

Tendons and Ligaments Compared to Muscle Fibers

It’s been shown that tendon and ligaments degrade slightly as a result of training, and then regenerate to regain homeostasis and strengthen slightly during the recovery period (see figure to the right). This is quite similar to the process by which contractile muscle fibers hypertrophy from training. One critical difference between muscle and connective tissue, however, comes down to the limited blood flow and nutrient supply available to tendons and ligaments.

While well-perfused muscle recovers rather quickly (typically in 24 – 48 hours), connective tissues can take 48 – 72 hours or more to recover from an intense workout or day of hard climbing. Submaximal climbing and training are possible during this recovery period, but back-to-back days of high-intensity or high-volume training will result in a homeostasis perturbation that may come across as slight transient pain in your finger tendon pulleys, elbows, and shoulders. Chronic over-training and under-resting may escalate the condition to the point of an acute tear (e.g. A2 pulley) or tendinosis. This may help explain why climbers and other elite strength/power athletes so frequently succumb to tendinopathy, and incur tendon and ligament injury at a higher rate than other athletes.

How to Nourish Tendons and Ligaments

Connective tissues receive poor blood flow, so nourishment occurs primarily by way of synovial fluid diffusion during mechanical loading (see figure to the left). Consider the fact that tendons and ligaments are comprised mostly of collagen and water. During mechanical loading and deloading, fluid is squeezed out of (and flows back into) the connective tissue similar to the squeezing and releasing of a sponge in a bucket of water. This flow of fluid brings amino acids into the loaded tendons and ligaments. This delivery of nourishment mostly ceases with the end of exercise.

Now consider that climbers (like other serious power athletes) tend to train and perform largely on an empty stomach. Significant meals are typically consumed post-workout, which great for nourishing muscles but less than ideal for nourishing tendons. The resulting undernourishment of connective tissues, combined with chronic intensive training and climbing, then leads to progressive degradation of the most strained tendons and ligaments.

The bottom line: You can best nourish connective tissues 30 to 60 minutes before training, whereas the optimal feeding time of muscle is during the post-workout period of elevated blood flow.

Supercharged Collagen

The collagen structure of tendons and ligaments consists of a repeating sequence of amino acids. Glycine makes up one of every three amino acids. Proline or hydroxyproline cover another third of the amino acid chain. Hydrolyzed collagen has been shown to spike serum glycine and proline concentrations within one hour. This practice bathes tendons and ligaments with glycine, proline, and hydroxyproline during a workout, climbing, or rehabilitative session.

Studies by Greg Shaw and Keith Baar have shown that consuming vitamin C-enriched hydrolyzed collagen before tendon and ligament training approximately doubles collagen synthesis after exercise. Interestingly, consuming hydrolyzed collage without vitamin C did not lead to an increase in collagen synthesis! This is not surprising, however, as vitamin C is an essential co-factor in collagen synthesis. In a fasted pre-workout state, vitamin C levels in the blood and tissues remain too low to support collagen synthesis. Therefore, Grandma’s “hair & skin support” hydrolyzed collagen won’t be very effective for feeding the highly-stressed connective tissues of climbers.

Maximizing the synergy of these training and nutritional interventions requires proper timing of the right exercises and the right nutrients. To provide tendon cells with the necessary amino acids for strengthening structural and force transfer proteins, you must consume the vitamin C-enriched hydrolyzed collagen 30 to 60 minutes before training. Supercharged Collagen from PhysiVantage is the only product designed specifically for hard-training climbers and other tendon-straining power athletes! Supercharged Collagen is further enhanced with the anabolic-signaling amino acid l-leucine and, additionally, further fortified with l-tryptophan. This makes Supercharged Collagen the only collagen powder on the market that is both a complete protein source and vitamin-C enriched.
