Lunges, squats and holds for stronger tendons and ligaments
(SACRAMENTO)

UC Davis Health molecular exercise physiologist Keith Baar specializes in sports medicine. He studies the effects of exercise on bone, muscle and tendon health.

In this Q&A, he discusses how intensive exercising after injury or when overweight can cause damage to ligaments and tendons. He also talks about the importance of integrating isometric or static exercises into our fitness routines.

Baar is a professor in the Departments of Neurobiology, Physiology and Behavior and Physiology and Membrane Biology.

Isometric or static exercises can enhance skeletal health.

Many people who are overweight may find it hard to start exercising. Why is this, according to your research?

People who have type 2 diabetes, and in many cases are overweight or obese, have metabolic problems. Society always says that if these people just ate better and exercised more, they would be fine. But data from Denmark shows that if they aggressively start exercising, they will actually rupture tendons. In fact, they are three times more likely to develop tendon problems if they do this, than if they were to decrease their weight slowly and then gradually increase their activity. Our research is starting to explain why.

People with kidney disease, are older, on bad diets, or are overweight or obese make less collagen. Yet, we’re telling them all to go out and exercise more. But that is putting them at a pretty big risk for catastrophic injuries to their tendons. If they do get a serious tendon or ligament injury, this increases their risk for heart attacks and further metabolic diseases.

What is a safe way for people recovering from injuries or who are overweight to exercise?

Classically, most people think about running, walking and rhythmic exercises that are associated with impact forces on the ground. Those impact forces are basically absorbed by our tendons, cartilage and bones. If we go out and start running when we are not in the best shape, there is a greater risk that we will cause injuries to these tissues, even if we are not overweight.

For example, our data have shown that when a person who has had a leg in a cast for a while goes back to exercising and normal activities, the leg that was not in a cast gets stronger and better, and the previously casted leg does not improve nearly as much — about threefold less. We think that is a really big issue for how people recover after any injury.

If we’re going to start exercising, we can’t only go out and run or walk. Instead, our research shows that when we add long isometric holds, the tissues, like our tendons and muscles, improve better. Adding these exercises helps build muscular strength and endurance.

What are isometric exercises?

Isometric or static exercises are moves that involve contracting or tightening the muscles without changing their length. They are positions that hold the body or limbs in a fixed position for a period of time. They include planks, squats, lunges and many more positions.

We hear about walking 10,000 steps a day. Is there a golden number for how many times per week to do isometric exercises?

It is totally fine for people to go out and get their steps. When they finish their steps, we would have them do a couple of simple movements, like holding a lunge for 10-30 seconds. To do this, they simply put one foot in front of the other. Then, they bend down so their back knee is just above the ground. That’s a great movement because it will strengthen the Achilles tendon on one leg and the patellar and the quadriceps on the other leg. We would do that kind of exercise at the end of our walk or run or whatever best fits into the person’s routine.

And then you do two or three different moves like that. You hold them for 10-30 seconds each. That’s all you need to do to keep those tissues healthier in the long run.

In another study, we worked with a professional rock climber who helped us get over 500 people to participate in training using a hangboard. A hangboard or a fingerboard is a training tool to increase hand and finger strength. The study showed that when they do these 10-second isometric holds, where people put only part of their body weight on their fingers, their tendons get this long low-intensity isometric that actually increases the strength of those tendons as much as if they were to lift or hold as heavy a weight as possible.

What you want to do is add in those low-intensity, longer-hold isometrics (especially for the legs) to your walking, running or pickleball exercise. The two types of exercise have an additive effect that keeps you healthy and actually makes you stronger.

Prepare for Ski Season With These Workouts

Skiing can be a whole lot of fun when the snow starts flying. But your body can take a beating on the slopes if it’s not properly prepared.

Sports medicine specialist Molly McDermott, DO, shares how to get ready for ski season with some workouts and strategies.

Ski training routine

Some elite skiers start training at the tail end of spring — about six months before they ever hit the slopes. Others may need less time. In general, Dr. McDermott recommends training at least six to eight weeks before your first outdoor adventure.

As part of your routine, you’ll want to focus on ski workouts that build:

  • Strength
  • Endurance
  • Flexibility
  • Neuromuscular control (also known as muscular coordination)

Trying to jump into a sport when you haven’t intentionally trained is difficult and challenging, says Dr. McDermott. That’s especially true given the physical demands that come with skiing.

“You want to train your brain, nerves and muscles to really build stability and balance so you can have more control over how you jump and land,” she notes.

Ski exercises

Ski-focused training puts a strong emphasis on lower-body exercises, targeting everything from your glutes to your ankles. But you’ll want to take a full-body approach to ski exercises, which means working on your core and upper body as well.

“You’re going to have to make real-time decisions when you’re out on the slopes,” stresses Dr. McDermott. “You’ll need to strengthen your whole body to be able to do things like pivot or change direction, keep your balance, propel yourself forward and withstand the impact of skiing.”

Dr. McDermott recommends starting with just bodyweight exercises if this is your first go at it. More experienced athletes can focus on higher weights or machines. In general, she recommends doing three sets of 10 to 15 reps each. Then, as you work through your training, you can progressively load your weight, sets, reps or how long you exercise to continue building strength and endurance.

Here are some workouts that lend themselves to skiing.

Dynamic warm-up

Warming up before any workout is key, especially right before you hit the slopes. The International Ski and Snowboard Federation agrees. Dynamic warm-ups and cool-downs are highly effective for preventing injury and improving performance.

Consider starting and ending your ski workout with five to 10 minutes of:

  • Jogging
  • Using an elliptical
  • Walking on a treadmill

“You’re warming up your muscles and then stretching them, as opposed to static, cold stretching,” explains Dr. McDermott.

Squats

“Squat maneuvers help make sure you have the coordination of your nerves and your muscles working together so your muscles are strong and keep your body aligned — in particular, keeping your knees from turning in,” says Dr. McDermott. “As squats become easier, you can progress to squat jumps.”

  1. Stand with your feet shoulder-width apart with your toes pointed slightly outward.
  2. Hinge at your hips, bend your knees and slowly lower your body (as if sinking into a chair).
  3. Lower until your thighs are parallel to the ground, keeping your knees in line with your toes and your weight on your heels.
  4. Hold the position for three to five seconds.
  5. Shoot up quickly to your starting position by pushing through your heels.
  6. Repeat this process for 10 to 15 reps.

Side-lying hip abductors

Hip abductor exercises help with skiing because they focus on balance, control and building strength in your hips, glutes and thighs.

  1. Lie down on your side with your legs extended straight. Your right leg should be on top of the other and you should rest your head on your left arm.
  2. Keeping your hips steady, lift your right leg so your knees are no longer touching. You should feel a stretch in your upper thigh and hip.
  3. Slowly lower your right leg.
  4. Repeat for 10 to 15 reps, then switch sides and continue.

Calf raises

Calf raises help improve ankle mobility and calf strength — all needed for those quick turns while skiing.

  1. Stand with your feet hip-width apart, with your arms hanging at your sides.
  2. Slowly lift the back of your heels until you’re standing on the balls of your feet.
  3. Hold this position for one to two seconds before lowering back down.
  4. Repeat for 10 to 15 reps.

Skater hops

“Skater hops are single-leg hops from side-to-side,” describes Dr. McDermott. “These are really going to help you in certain ski maneuvers.”

  1. Stand with your feet hip-width apart and your hips and knees bent at a 45-degree angle.
  2. Push off the floor with your left leg so that you jump to the side, landing on your right leg.
  3. Keep your knees bent and your left leg crossed behind your right (as if you’re skating).
  4. Then, jump back to the opposite side, crossing your right leg behind your left.
  5. Repeat this process in quick succession for 10 to 15 reps, jumping as fast and far as you’re able.
  6. To maintain momentum, it helps to swing your left arm forward as you’re pushing off with your left leg and vice versa.

Shoulder shrugs

“Shoulder shrugs are a good ski exercise because they help build the upper trapezius muscles that connect with your neck,” says Dr. McDermott. “They really work on your posture.”

  1. Start by standing tall, feet hip-width apart.
  2. While looking straight ahead, lift both of your shoulders and slowly roll them backward in a circle for 10 seconds.
  3. Repeat the process by circling your shoulders in the opposite direction for 10 seconds.

Chin tucks

Chin tucks involve a gentle range of motion to improve posture and strengthen neck muscles.

  1. While sitting or standing in a relaxed position, look straight ahead and lightly touch the bottom of your chin with your index finger.
  2. Gently pull your head and neck back so your chin moves away from your finger.
  3. Hold this tucked-chin position for up to 10 seconds before slowly extending your head and neck forward to the starting chin position.
  4. Repeat this process for 10 to 15 reps.

Push-ups

“Push-ups are good for strengthening your shoulders, chest and core, which helps with balance and stability when you’re skiing,” says Dr. McDermott.

  1. Kneel on all fours with your palms flat on the floor in front of you and your fingers facing forward. Hands should be shoulder-width apart and directly below your shoulders.
  2. Lift your knees off the floor and straighten your legs.
  3. Bend your elbows and tuck them to your sides as you slowly lower your chest and chin to the floor.
  4. Push through your palms until your arms are fully extended. Don’t let your hips or back dip to the ground — your head, spine and butt should all be aligned.
  5. Repeat this process for 10 to 15 reps.

Planks

This exercise targets your wrists, forearms, core and upper body — all areas that promote stability and strength while skiing.

  1. Get into a push-up position, with your legs extended and your elbows directly beneath your shoulders.
  2. Hold this upright push-up position for 10 to 15 seconds, with your abs engaged and butt and back aligned.
  3. For a modified challenge, you can lower your knees to the floor while holding this position.
  4. For a deeper stretch, you can rock your hips back and forth, or lower down to your elbows for a low plank.

Bridges

Bridges help strengthen your glutes, which help guide and direct your skis.

  1. Lie on your back with your knees bent, feet on the floor and arms at your sides.
  2. Squeezing your butt and abdominal muscles, push through your heels to slowly lift your hips toward the ceiling.
  3. Keep your back straight and your arms pressed into the floor at your sides.
  4. Hold this position for a few seconds, before slowly lowering your hips to the floor.
  5. Repeat this process for 10 to 15 reps.

Oblique twists

Also known as a Russian twist, this exercise focuses on your abdominal muscles and core strength. It helps with skiing because it supports your ability to rotate, turn and move quickly.

  1. Sit on the floor with your knees bent and your feet flat.
  2. Lean back at a 45-degree angle and squeeze your abdominal muscles.
  3. Extend your arms out straight in front of you and clasp your hands together.
  4. Engage your core as you twist slowly to the right as far as you feel comfortable, moving your arms in the direction you’re turning.
  5. Return back to center, pause and then twist to the left side.
  6. Repeat this process for 10 to 15 reps.

Cardio exercises

Skiers can also benefit from cardio exercises that get their blood flowing and build aerobic endurance, like:

  • Cycling
  • Running
  • Swimming
  • Rowing

“Build cardiovascular and low-impact activities into your training routine to help improve your performance and increase your endurance,” advises Dr. McDermott. “Some days you can break it up into sets or you can do 30 minutes straight.”

A note before hitting the slopes

A big part of ski training is getting your body acclimated to cold-weather exercises. For athletes who live in areas where winter runs strong, it helps to train early and get that outdoor exposure as temperatures begin to drop during the fall.

Others who live in warmer climates might benefit from taking cold showers, ice baths or lowering indoor temperatures weeks before heading out on a ski trip.

Once ski season begins, make sure you warm up before heading outdoors, stay hydrated and keep moving to keep your body warm.

“When you’re skiing, a lot of unexpected things happen,” cautions Dr. McDermott. “The weather changes and things happen really fast. So, you want to be physically and mentally prepared before you hit the slopes, making sure you’ve got the right equipment, the right clothing and you’re prepared in case of injury.”
